The synthesis of nanostructured NiCrAlY powders for plasma sprayed thermal barrier coatings

Author(s):

Mohammad Sakhawat Hussain -- Mohammadreza Daroonparvar


Abstract
| Pages: 1-9
Thermal barrier coatings (TBCs) are used to protect hot sections of industrial gas turbine blades against high temperature corrosion and oxidation. They usually consist of a thermally insulating ceramic top layer (Yittria Stabilized Zirconia or YSZ) and an oxidation resistant metallic bond coat (MCrAlY) thermally sprayed onto the nickel-based superalloy substrate surfaces. Currently MCrAlY powders, up to 100μm in diameter are used in the production of thermal barrier coatings by the industrial gas turbine component manufacturers. It has been found that the nanocrystalline MCrAlY layer provide better oxidation behavior than the currently used microstructured MCrAlY layer at elevated temperatures. In this research work, nanocrystalline NiCrAlY powders were manufactured using a conventional Ni22Cr10Al1.0Y powder as the base material using a planetary ball mill device. The microstructural characterization of NiCrAlY powders before and after milling were explored using X-ray diffraction, scanning electron microscope equipped with energy dispersive spectrometer. The results indicated that the synthesized NiCrAlY powders mainly consists of two phases: γ (Ni,Cr-rich) and γ’ (Ni3Al).

Distribution of Radionuclide Concentration with Proximity to the Lagoon in Lagos State, Southwestern Nigeria

Author(s):

T. J Ojo -- B. O Afolayan


Abstract
| Pages: 1-4
The radioactivity of Lagos State in the Southwestern Nigeria was determined using an HpGe based, low level passive gamma-counting system. The main radinouclides analyzed in the samples were the progenies of 238U and 232Th. The other two isotopes were the naturally occurring 40K and the anthropogenic 137Cs. The results of the study showed that the average specific activity concentration of 238U, 232Th and 40K have consistent values with published data for many other countries in the world. The presence of the fission product 137Cs could be traced to the fallout of the nuclear tests in the Sahara desert and probably, some effects of the more recent nuclear reactor accident at Chernobyl in 1986.

A general theoretical design of semiconductor nanostructures with equispaced energy levels: preliminary report for quantum wells in semiconductor ternary alloys (AxB1-xC)

Author(s):

Arthur Imooah Ejere -- Godfrey E. Akpojotor


Abstract
| Pages: 1-10
The purpose of this study is to formulate a general theoretical design of equispaced energy levels for semiconductor nanostructures. Here we present a preliminary report for the design of equispaced energy levels for quantum wells (QWs) in semiconductor ternary alloys (AxB1-xC). The procedure is by mapping the envelope function Schrodinger equation for a realistic QW, with the local conduction-band edges as the potential experienced by an electron in the QW into an effective-mass Schrodinger equation with a linear harmonic oscillator potential by the method of coordinate transformation. The electron effective mass and potential are then obtained as the signatures for the equispaced energy levels for QWs in semiconductor ternary alloys.

Author(s):

Alpana Tiwari -- N. K. Gaur


Abstract
| Pages: 1-5
We have incorporated the translational rotational (TR) coupling effects in the framework of three body force shell model (TSM) to develop an extended TSM (ETSM). This ETSM has been applied to reveal the second order elastic constants (C11,C12 and C44) in the dilute regimes 0≤ x ≤ 0.50 as a function of temperature for 0K≤T≤320K. The anomalous elastic behaviour in C44 has been depicted well by ETSM results in the orientationally disordered (NH4Br) x(KBr)1-x mixed crystals. In order to present a visual comparison of the TRcoupling effect on second order elastic constants, we have evaluated the SOECs with and without TR coupling term in ETSM.

Matter-Antimatter : An Accentuation-Attrition Model

Author(s):

K. N. Prasanna Kumar -- Alberto Molina-Martinez


Abstract
| Pages: 1-113
A system of matter dissipating antimatter and parallel system of antimatter that contribute to the dissipation of the velocity of production of matter is investigated. It is shown that the time independence of the contributions portrays another system by itself and constitutes the equilibrium solution of the original time independent system. With the methodology reinforced with the explanations, we write the governing equations with the nomenclature for the systems in the foregoing, by concatenation process, ipso facto. We discuss following systems in all its predicational anteriorities, character consonations, ontological consonances, primordial exactitude, accolytish representation, differential relations, and concomitant contiguous similarities. (1) Antimatter as an integral part of the electromagnetic phenomena. (2) Electricity consists of the flow of electrons and positrons in opposite directions along a conductor (not only of electrons, as current accepted knowledge describes), induced by the crossing of a magnetic field through the conductor. (3) When a charged particle passes through matter at rest it will cause the production of electron pairs, that is, electrons and positrons, but if nothing separates them by force, they will reunite after the passing of the charged particle, nullifying each other, and the atoms of matter will be back at rest. (4) In order to preserve the law of conservation of energy, the amount of energy required to break free the electron and the positron from a bielectron (a theoretical dual particle containing an electron and a positron) must be equal to the amount of energy released by a matter-antimatter encounter of the same particles. (5) When a conductor is at rest all the bielectrons are located at their respective orbits in the conductor's atoms, generating no electric charge. (6) When a conductor is placed under a moving magnetic field, its otherwise stable bielectrons will break apart into electrons and positrons, which will flow in opposite directions along the conductor. At the closing of the circuit, electrons and positrons, attracted to each other by their opposite charge, reunite into bielectrons releasing an equal amount of energy as initially required to separate them. (7) Matter gormandizes antimatter (Antimatter has to pre-exist to be able to appear in a collision of particles. We are not creating antimatter; antimatter is there, intermingled with matter. Particle collisions do not “produce” antimatter; they separate antimatter from the particles of which it is part). (8) We assume that should there be another force in physics: the force of attraction between matter and antimatter and give a model. We shall call it Bundeswehr (German for "Federal Defense"). So Bundeswehr binds matter and antimatter. (9) At the closing of the circuit the free electrons and positrons, pushed forward by their own “pressure”, are irresistibly pulled by the attraction of their antimatter counterpart. It is this process of mutual attraction and continuous reunification into bielectrons which causes the flow of electrons and positrons along the conductors. Paper answers, not wholly or in full measure, but substantially the relationship between dark matter and antimatter and speculates in epiphenomena and phenomenological form the circumspective jurisprudence of consideration of the antimatter as dark matter. This also answers the long standing question in cosmology that why matter is prevalent in the universe in contrast to antimatter. The paper seems to confirm antimatter as an intrinsic constituent of ordinary matter; antimatter as an integral part of the electromagnetic phenomena; the existence of a new particle namely bielectron, consisting of an electron and a positron joined together within the atom; that matter and antimatter preceded the big-bang and their violent encounter may have been the actual cause of the big-bang itself; that matter and antimatter have a pacific coexistence in today’s universe, after the big-bang; the possible existence of a new force in physics namely Bundeswehr, which would recombine and keep matter and antimatter particles together.

| Pages: 1-3
We have studied statistically correlative analysis of long-term modulation of cosmic ray intensity (CRI) with coronal mass ejections and solar flare index for the period of 1997 to 2010 (23rd and 24th solar cycle). Inverse correlation has been found between solar activity parameters cosmic ray intensity (CRI), coronal mass ejections, solar flare index. Negative correlation with correlation coefficient -0.83 has been found between cosmic ray intensity and coronal mass ejections. Negative correlation with correlation coefficient -0.70 has been found between cosmic ray intensity and solar flare index number.

Analytical Model for the Effect of Pressure on the Electronic Structure of Germanium Nanocrystals

Author(s):

Noor H. Aysa -- Bashaeer S. Mahdi -- A.M. Abdul-Lettif


Abstract
| Pages: 1-9
The electronic structure modification of germanium nanocrystals under the condition of external pressure has been investigated, in order to gain a better understanding of their relevant properties. In this paper, an atomistic insight into the effect of size-pressure variation on the electronic structure of germanium nanocrystals (of 8, 16, 54 atoms) is performed. The effect of pressure on the structural and electronic properties of germanium nanocrystals has been investigated using the large unit cell within the framework of ab initio restricted Hartree- Fock theory and the linear combination of atomic orbital approximation included in Gaussian03 software by considering the effects of size and pressure. Cohesive energy, indirect band gap, valence bandwidth and bulk modulus are all obtained, which is consistent with understanding the interdependence of these quantities and their common atomistic origin originates with size- and pressure-induced change, leading to a variation of the crystal potential. Theoretical results are compared with the experimental measurements. The calculations show an agreement of the calculated lattice constant at equilibrium point, cohesive energy, valence bandwidth, and bulk modulus with the experimental data. Computed band gap is greater than the experimental value. That is what expected from Hartree-Fock method. Band gap shows a good trend compared to theoretical values. The calculations of the effect of pressure on the aforementioned properties are investigated. It is found that the valence bandwidth decrease with the increase of pressure, and cohesive energy decrease with the increase of tensile pressure in 8 atoms while it increase in both 16 and 54 atoms. Lattice constant increase with pressure in three crystals, and energy gap decrease with pressure in both 8, and 16 atoms crystals and increase with pressure in 54 atoms nanocrystal. The maximum value of pressure is taken to be 7.6 GPa, because beyond this value, the phase of Ge transforms from nanocrystals to another phase.

Problem of Integration with Respect to Unbounded Measures on the Set of Projections

Author(s):

Bassi, I. G. -- Markus Samaila -- Okechukwu C. E.


Abstract
| Pages: 1-7
We note if j is a normal weight on M, then n M j| is a measure on projections and if a measure on projections can be extended to a normal weight, then the problem of constructing an integral with respect to this measure reduces to the problem of constructing an integral with respect to the weight. We therefore present several methods of constructing noncommutative integration which gives a survey of the contemporary state of the theory in the von Neumann algebra (M) with respect to weightj. For every aÎ [0,1], the Banach space p, L a ( ) j is isometrically isomorphic to the space Lp(t) and the space p, L a ( ) j is, by definition, the Banach space completion of 1/ p ma in the norm p, . . a .We construct the scale of Lp(j) spaces (1£ p £ ¥) with respect to a faithful normal semifinite (f.n.s.) weight j on a von Neumann algebra M. These spaces are realized by operators. This is achieved by extending the original algebra M, and the Hilbert space where M originally acted is altered, as well. In the construction of the scale, the concept of an operator-valued weight is used. We discuss the problem of integration with respect to measures on projections which remains open for unbounded measures (m(1) = +¥) and their structure has been studied only for the algebra ℒ(ℋ).

Abstract
| Pages: 1-17
Cracks on concrete and walls could be bothersome for quality of life and for property claims. Geophysical investigations was carried out around Faculty of Science and BACOSA buildings of Bowen University Temporary site, Iwo with a view to establish the possible cause(s) of failure of buildings within the study area. The geophysical methods used for the investigation were the Very Low Frequency Electromagnetic (VLF-EM) and the Electrical Resistivity (ER) methods. The VLF-EM measurements were taken at an interval of 10m along six traverse lines in the E-W and S-N directions. From the result of the VLF-EM, six VES stations were occupied in the study area involving Schlumberger configuration with half current electrode separation (AB/2) varying from 1 to a maximum of 65m. The 2-D VLF-EM models generated showed a network of suspected linear (geological) structures such as fractures, faults and contacts within the study area. The VES curve types obtained in the area include HA, KH, QH and AA with HA type curve dominating. Four subsurface geologic layers were delineated in the study area. These include the topsoil, weathered layer, clayey sand and fresh basement with resistivity ranging from 121.3 to 771.2 ohm-m, 134.4 to 595.8 ohm-m, 81.6 to 951.9 ohm-m and 1474.7 to 5134.4 ohm-m respectively. The thickness range from 0.5 to 2.4m, 1.8 to 9.8m and2.7 to 24.5m. Depths to the bedrock are generally less than 40m. The resistivity of the weathered layer beneath the topsoil in which the foundation is seated was found to be low within the study area, ranging from 134.4 to 595.8 ohm-m typical of clayey materials. From the models generated from VLF-EM and resistivity data, the distressed structures were found to be situated within the areas with a fairly high concentration of fractures, faults and contacts and relatively low resistivity values(less than 1000 ohm-m) typical of incompetent clayey formation.

Author(s):

Margarita Kuqali


Abstract
| Pages: 5-10
A large-scale circulation velocity, often called the "wind", has been observed in turbulent convection in the Rayleigh- Benard apparatus with a container of an aspect ratio of unity. Temperature fluctuations measured in different positions inside the container for Rayleigh numbers of the order of 1011 when the flow is fully turbulent, are analyzed with auto and cross correlation. It is found that the trajectory of the mean wind has the shape of one convection cell with the size of the order of the container.

Author(s):

F. M. Abou El-Ela -- A. Z. Mohamed


Abstract
| Pages: 11-19
Inverse of Dielectric Function of highly doped GaN has been calculated by using Lindhard formalism. For simplicity collisional damping, nonparabolicity and the coupling between various electrons and holes were neglected. The inverse of the dielectric function for both Fermi- Dirac and Maxwell Boltzman distribution showed antiscreening peak at small phonon wave vector. On the contrary, both Thomas Fermi and Debye inverse of dielectric function showed screening as expected at same phonon wave vector. There is a sharp growth in the antiscreening peak in the inverse of dielectric function at carrier temperature 77 K and 300K, accompanied with a singularity at carrier concentration greater than 24 3 5 10 − x m .

Author(s):

E.I Ugwu -- H.U Igwe -- D.U Onah -- N.N. Nwafor


Abstract
| Pages: 9-13
Two groups of cadmium selenide thin films deposited at 250C and 740C respectively on glass substrates by chemical bath deposition method were studied. A moderately stable sodium selenosulphite (Na2SeSo3) was used as a source of Se2- ions. To prevent spontaneous precipitation and ensure ion-by-ion deposition on the substrate, TEA was used as a complexing agent. The optical characterization was centered on transmittance, reflectance for the annealed and various annealing temperature of thin film. The structural nature was obtained from X-ray diffraction (XRD) analysis. The optical properties were obtained from absorption and transmittance data within the range of 200-to-1000nm. Some of the films were found to have a good transmittance and low reflectance hence suitable for window coatings for cold climates and antireflection coatings.

Estimation of Flow Accelerated Corrosion (FAC) in Feeder Pipes using CFDd Software Fluent

Author(s):

Dheya Al-Othmany


Abstract
| Pages: 4-8
Flow Accelerated Corrosion (FAC) is a corrosion mechanism induced by a combination of various physical, chemical and hydrodynamic factors that results into wall thinning of piping. Prediction and modeling of this phenomena is needed to account for local and non uniform distribution flow and mass transport characteristics This can be done by using CFD software FLUENT. In a number of nuclear reactors a feeder wall thing rate of 0.1084 mm/EFPY has been reported. In this study emphasis is given on two objectives. The first one was to perform CFD analysis using FLUENT. Feeder channel of a typical reactor was modeled as it showed the maximum wall thinning rate of 1.1 mm per year. However in this analysis no consideration was given to the chemical treatment of working fluid. The experimental studies of FAC were done at various temperatures in order to determine the threshold temperature for FAC. However, due to experimental limitations no significant FAC was found for water temperatures up to 90°C.

Author(s):

Timothy Yakubu Woma -- Ayoola W. Fagbenro


Abstract
| Pages: 5-10
Time lapse seismic also called 4D seismic is one of the recent techniques employed in petroleum production monitoring and management within the last two decades, it involves taking two or more 3D seismic at different calendar times over the same reservoir .Case study of 4D seismic in the USA, North sea, Indonesia and of course Nigeria have shown that the expenditure on 4D seismic is justified. Key benefits of 4D seismic include optimising injector profile management, optimising well placement, defining barriers to flow or compartments, assessing zones of undrained and bypassed oil, all of which leads to cost effective increase in oil and gas production. Onshore oil fields in Nigeria should also have 4D seismic and more publications from companies operating in Nigeria is encouraged.

Author(s):

Bassi, I. G. -- Markus Samaila -- Okechukwu C. E.


Abstract
| Pages: 8-14
Important information about stationary flows (BI)IÎI is contained in moments of the corresponding Lé vy process. We consider the case where we have an order invariance of the moments of the increments, in the sense that such moments do not change if we shift the increments against each other, as long as we do not change the relative position of the intervals. We then show that for large classes of quantum Lé vy processes one can make precise statements about the time behaviour of their moments.

Author(s):

Abo-el-nour N. Abd-alla -- Fatimah Alshaikh


Abstract
| Pages: 20-33
The objective of this paper is to investigate some aspects of dispersion relation of flexural waves propagation in a transversely isotropic hollow circular cylinder of infinite extent placed in a primary magnetic field. A frequency equation appropriate to the hollow circular cylinder is obtained by using the lame (Helmholtz) potentials for arbitrary values of the physical parameters involve as well as the primary magnetic field. Numerical calculations have been carried out when the cylinder is made of the material of Zinc Oxide. This study shows that waves in a solid body propagating under the influence of a superimposed magnetic field can differ significantly from those propagating in the absence of the magnetic field. Also, one may see that the effect of the primary magnetic field is to increase the values of the materials constants. Finally the results are given for different values of the primary magnetic field and presented graphically. The standard results of the previous investigations have also been deduced as particular cases.

Abstract
| Pages: 20-24
The paper presents a method which allows the calculation of the atmospheric distortion of radar pules, provided that the influence of the atmosphere is to transfer the transmitted signal through a duct. The polarization of the primary sources, whose moment varies arbitrarily in time, is chosen in such a way that it allows the exact determination of the electric field strength at some field point above the duct layer. We can determinate the transient behavior of the electric field strength at any distance above the duct.

Abstract
| Pages: 11-14
The partial replacement of rare earth cation by sodium introduces large size and charge mismatch at A-site affecting the bulk modulus and thermal properties of RMnO3 which in turn makes them suitable candidates for thermoelectric applications. Thermal, elastic, cohesive properties of sodium doped Rare Earth manganites R1- xNaxMnO3 (R3+= La, Pr, Tb) has been studied by means of a Modified Rigid Ion Model (MRIM) and AIM theory. Lattice specific heat (Cp) of Pr0.8Na0.2MnO3, and Tb0.85Na0.15MnO3 as a function of temperature (1K≤T≤ 350K) is found to be in agreement with the published data. The trend of variation of Debye temperature (θD), thermal expansion (α), bulk modulus (B) and cohesive energy (φ) with A-site cationic radius is predicted probably for the first time for these technologically important doped rare earth manganites.

Abstract
| Pages: 9-17
ZnS nanoparticles were synthesized using wet chemical co-precipitation method. During synthesis, polyethylene glycol (PEG) and carboxylmethly cellulose (CMC) molecule were used as capping agents. The effect of the capping materials was analyzed for their effectiveness in limiting the growth of ZnS nanoparticles. The prepared ZnS nanoparticles were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-rays (EDX). The estimated crystal sizes from XRD are 3.92 nm and 3.89 nm for ZnS/PEG and ZnS/CMC nanosize semiconductors respectively. The effect of capping agent on the energy band gap of the capped ZnS nanoparticles were blue shifted at 0.16 eV and 0.28 eV for ZnS/PEG and ZnS/CMC respectively. Fourier transform infrared spectroscopy (FTIR) confirms the interaction of the capping agents with ZnS.

The nuclear optical model has been used in the analysis of elastic scattering for the reaction He B 4 +10 . This model has six optical parameters; the depth, Coulomb radius and the diffuseness on both the real part and imaginary part potentials. Out of the six, five parameters were chosen and for this case diffuseness parameter on the imaginary part was kept constant. The five parameters were used to calculate the partial wave S-matrix, the differential cross section and the reaction cross section as a ratio to Rutherford cross section. The partial wave scattering data was obtained basing on the quantum mechanical optical code for all the stated Laboratory energies. The angular distribution for the reaction He B 4 +10 for both reaction cross section to the Rutherford cross-section and differential cross section ranging from centre of mass angles ( ) cm θ of 0 0 0 −180 were also obtained for all the energies, ( = 5, Lab E 7, 12 and 15 MeV) and whose data and graphs are presented.

Abstract
| Pages: 15-30
This study deals a new concepts of some physical reciprocally quantities which are vectors or scalars and its relationship with the fundamental quantities. The reciprocal of kinematics dimension quantities of moved particle for linear, rotational and circular movement are resulted the quantities that so called the time quantities such as time velocity, time acceleration . Other derivative quantities were derived from the principle equations to produce reciprocal movement equations. For dynamical mechanics, the quantities were derived from the principle equation such as time force, momentum, torque, energy,…ect. Also some reciprocal quantities due to electricity equations include the reactance, electric current, conductivity, …ect, and its derivative quantities are introduced time current density, time power. The results show that the concept of reciprocal of some quantities describes the quantity from two faces, first the principle quantities as were known, which depend on time and second the reciprocal of this quantity, that independent on time and gives a new concept to the same quantity, describe the motion of particle or field. This will add a complete meaning of movement of a particle , if a particle is a moving neutral or charged particle, or intrinsic quantity.

Author(s):

Abo-el-nour N. Abd-alla -- Fatimah Alshaikh


Abstract
| Pages: 34-45
The propagation of extensional and flexural motions of generalized thermoelastic waves in a homogeneous, transversely isotropic plate of finite width is considered. The frequency equations for the plates in closed form and suitable mathematical conditions for symmetric and antisymmetric wave modes propagation are derived. Numerical calculations for three various theories of generalized thermoelasticity is carried out. In each case the real and imaginary parts of the frequency equation as a function of phase velocity for different values of thermal relaxation times are illustrated graphically. It is found that, the frequency equations of the extensional and flexural motions can be oscillate with respect to the medial of the plate. Moreover, it gets modified due to the thermal relaxation times and anisotropic effects. Finally, the results for the coupled thermoelasticity can be obtained as particular cases of the results by setting thermal relaxation times equal to zero

Abstract
| Pages: 18-23
Kalman filtering is a multiple-input, multiple-output filter that can optimally estimate the states of a system, so it can be considered a suitable means for deformation analysis. The states are all the variables needed to completely describe the system behavior of the deformation process as a function of time (such as position, velocity etc.). The standard Kalman filter estimates the state vector where the measuring process is described by a linear system. While, in order to process a non-linear system an optimized aspect of Kalman filter is appropriate. Engineering Geodesy is the application of only geodetic methods for mapping certain geometric shape or of the topographic surface with respect to accurately define reference frame. Geodetic methods configure positions in Space with respect to the Earth and interpret the geodetic measurements in terms of a Euclidean Geometry. However Geodesy as discipline may unravel not only the geometric but also the kinematical and the physical nature of the Earth via geometric measures. At present, like in other Earth disciplines, Geodesy measurements depend on the dynamical and physical features of the Earth. One of the main issues of Engineering Geodesy is accurate prediction of value of structural deformation. Above storage Tank is like other deformable structure whose shape, form and safety is of interest to Engineering fields. The main purpose of structural deformation monitoring scheme and analysis is to detect any significant movements of the structure. Presented here is geodetic methods of determination of Velocity and Acceleration of deformable object in Time domain and predict deformation value using Kalman Filter. Analysis of the result indicated that there are correlations between the observed and the predicted deformation value for year 2004, 2008, 2010 and 2012 respectively.

Chagok, N.M. D. -- Fom, T. P. -- Izam, M. M. -- Domtau, D. L. -- Jwanbot, D. I.


Abstract
| Pages: 19-23
In this work, the empirical formula derived by Chagok and Gyang (2012)in conjunction to the AAO-1979 rule was used to predict values for the monaural impairment and the hearing handicap for exposure to steady-state broad-band industrial noise. The predicted values for the monaural impairment and the hearing handicap increase with exposure levels and therefore support the Equal Energy Hypothesis (EEH). The values of the hearing handicap are always higher than the corresponding values of the monaural impairment. The values of the monaural impairment and the hearing handicap show that all the values increase with sound pressure level, exposure time and age and that values of the impairment and handicap could be obtained for sound pressure level of 70dBA if the table is expanded to consider entries for higher ages and more exposures.

Abstract
| Pages: 31-37
Indium tin oxide (ITO) thin films have been prepared by spray pyrolysis using a very low concentration of indium precursor. The spray process parameter like the concentration of SnO precursor in spray solution, have been optimized for obtaining optically transparent, structure and device-quality ITO films. The material properties are reported by studying the structural and optical properties of the ITO films prepared at a relatively lower temperature of 574K. The surface morphology has been studied by atomic force microscopy it was found ITO films have nanostructured. The grain size and the roughness of the films doping concentration 2%, 4% and 6% was (76, 87 and 127)nm and (0.969, 2.56 and 1.61)nm respectively. The concentration rate 2% produces an overall shift to lower photon energies of the optical constant spectra and the optical transmission of greater than 85%, which is related to the increase in electrical resistivity. Characterization of ITO on glass and silicon has shown that increasing the concentration rate will increase in the optical band gap of the ITO films. Samples deposited at doping concentration 2%, 4% and 6% the optical gaps of 3.74 eV, 3.9 eV and 3.73 eV respectively.

Abstract
| Pages: 36-47
As watershed models become increasingly functional and useful, there is a need to extend their applicability to other locations to explore the possibility of calibrating and evaluating them in such new locations. This study used the “abcd” monthly water balance model for three catchments in different places in the United States in order to investigate the feasibility of this model in different regions. Although the regional calibration led to nearly perfect regional relationships between catchment model parameters and basin characteristics in catchments with little or no snow, practicality of this model in regions dominated by snow was questionable.

Himanshu Chauhan -- Swati Rawal -- R.K. Sinha


Abstract
| Pages: 38-45
The proposed paper presents the analysis of electromagnetic waves meeting at a point in terms of their particle characteristics. The observation that light beams moves un-deviated when encountered at a point, which is commonly justified on the wave characteristics of light, is now presented as momentum and wavelength exchange phenomenon of photon collision. Theoretical and mathematical justification of photon’s inter-collision, on the basis of their quasi-point particle behavior is offered and the observation of the non-variation of wavelength of light beams is explained. Thus, the observation of light’s non-deviation at the crossing point is explained as momentum exchange phenomenon on the basis of particle characteristics of light.

Abstract
| Pages: 28-36
The polymer composite used in the present study were made of polyvinyl alcohol (PVA) as a matrix and Iraqi egg shells as filler. Polymer composites were fabricated by mixing PVA with (5, 10, 15, 20, 25, 30, 40 and 50) wt.% of egg shells powder by using a magnetic stirrer at temperature 900C for 4hr to obtain homogeneous solution then samples were prepared by casting techniques. The ultrasonic measurements (transmittance, absorption coefficient and relaxation amplitude, acoustic impedance, compressibility and compressibility) of composites were carried out by using ultrasound technique. Measurement of DC conductivity and coefficient of thermal conductivity were done as a function to wt. % of egg shells. It was found that the samples contain additives of eggshells 5%, 10%, 20% and 30%, the attenuation decreased by increasing frequency up to 40 KHz and then increased after this frequency; while the sample contains 15% of the eggshells, the attenuation not alter significantly with increasing frequency. Sample with 50 % egg shell has two peaks at 20 and 30 kHz. As can be seen that the samples which contain a proportion of eggshells 5, 10, 20, 25, 30 and 40%, the transmittance coefficient increases with increasing frequency up to 40 kHz and then decreases and relaxation amplitude decreases with increasing frequency from 5 to 50 KHz. Generally observed acoustic impedance decreases with increasing eggshells except percentage 20%, where the highest value for the impedance. Compressibility generally increases with increasing of eggshells up to 40 % and then decreases. The electrical conductivity increase as concentrations of egg shells increase up to 30 % then conductivity decreases at 40 % then increases slightly at 50 %. It was found that coefficient of thermal conductivity increases with increasing of egg shells up to 40 % then decreases.

Abstract
| Pages: 24-29
The structural and mechanical properties of alkaline earth oxides mixed compound MgxSr1-xO (0 ≤ x ≥ 1) have been investigated under high pressure. Phase transition pressures are associated with a sudden collapse in volume. Phase transition pressure and associated volume collapses [ΔV (Pt)/V(0)] calculated from this approach are in good agreement with experiment for the end point members (x=0 and x=1). The results for the mixed crystal counter parts are also in fair agreement with experimental data generated from the application of Vegard’s law to data for the end point members.

A key component of the Millennium Development Goals is a call to halve by the year 2015 the proportion of persons without sustainable access to safe drinking water and basic sanitation in developing nations. This paper reports a study of the terrestrial radioactivity around Aluu landfill in Obiakpor Local Government Area of Rivers State, Nigeria. Measurements were carried out in the North, South, East and West directions of the Aluu landfill. An in- situ measurement was done using two well calibrated nuclear radiation meters (Radalert-100 and Digilert-50) and a geographical positioning system (GPS). Ten readings were taken in each direction of the landfill at intervals of ten (10) meters away from the landfill making a total of forty (40) sampling points. The mean site radiation levels all the four cardinal points ranges from 0.0123 0.0026 mR/hr (1.034mSv/y) to 0.0151± 0.0012mR/h (1.270mSv/y). The equivalent dose has an average value range of 1.001mSv/y to 1.270mSv/y which is slightly above the recommended dose limit of 1.0mSv/y for the general public. Comparison of the measured radiation level of site locations with the normal background levels show 21 locations representing 53% of the sampled area exceed the normal background level of 0.013mR/h. This study indicates that there is no immediate radiological health hazard for the general public, however there may be long-term health challenges.

Abstract
| Pages: 26-30
A 2D RZ VENTURE model has been developed for the Nigeria Research Reactor-1 (NIRR-1) and this model was used to perform neutronic analysis for the system using the code “VENTURE-PC”. The major homogenized regions in the 2D VENTURE model include the active fuel region and the control region while the remaining components in the system geometry where modelled as closely as possible. The reactor physics parameters generated from the neutronic calculations include excess reactivity, control rod worth, shim worth, shutdown margin. The model predictions of these parameters for NIRR-1 system were in good agreement with experimental results as well as the results from similar calculations using different nuclear analysis tools. This 2D RZ VENTURE model gives an excellent simulation of the Nigeria Research Reactor-1 and the model will be very helpful in the future analysis of the system, as well for developing an LEU core model for future conversion of NIRR-1 from HEU to LEU fuelled research reactor.

The nonlinear optical properties of an azo dye (1.8-Dihydroxy-naphthalin-3, 6 disulfonic acid- [2- (4-azo)]- N-(5-methyl-3-isoxazolyl)-benzene sulfonamide) are studied by using z-scan and diffraction ring technique with continuous wave (cw) laser at a wavelength of 532 nm. The obtained results for the nonlinear refractive index , 2 n , and the thermo-optic coefficients , dn / dT , are found to be of the order of 10−8 Wcm-2 and 10−6 K-1 respectively. The transmitted beam profiles, the distribution of intensity corresponding to the sample positions and D- distribution of rings number of each pattern variation for the azo dye samples have been studied. These results indicate that the azo dye is a promising candidate for applications in nonlinear optical devices.

Author(s):

A.Belahmar -- A.Chouiyakh


Abstract
| Pages: 38-46
Gold-Silica nanocomposite thin films were prepared by RF-magnetron sputtering technique on glass substrate at room temperature. Subsequent thermal treatment was used to promote nanocluster formation. The prepared samples were characterized by X-ray diffraction and optical absorption spectroscopy. After annealing, an increase of size accompanied by an increase of the lattice constant parameter is observed. A value of the surface stress coefficient of gold is f = 3.20 N/m has been obtained. Broad band absorption, with maximum absorbance at around 500 nm, characteristic of gold nanoclusters was observed after heat treatment. Experimental optical absorption spectra were modeled by the modified Mie theory. The plasmon peak red shift obtained from the simulation curves is compared to the calculated one from the variation of lattice constant parameter.

Abstract
| Pages: 39-47
Measurement of noise sound pressure levels in food processing industries, a social survey to determine the extent to which the workers were disturbed by the noise in the same industries, in Jos, were carried out. In all the industries, only one had equivalent continuous noise level below 85dBA. The results of the physical measurements showed that the noise was predominantly broad-band, continuous and steady state. Noisiness and perceived noise levels were obtained from the results of the physical measurements. The result showed that perceived noise levels were not more than 2dB higher than their corresponding equivalent continuous noise levels implying that the human ear perceives noise (2 dB maximally) higher than that measured by a sound level meter on A-weighting scale. For noise levels at 90dB and above small increase would result to higher noisiness increase. However, noise level and perceived noise level have continuous and steady dependence at all values. The correlation coefficient for noise rating and perceived noise level ϒ1=0.8599, and the correlation coefficient for noise annoyance and perceived noise levels ϒ1=0.8892, both showing strong positive correlations between objective and subjective assessment of noise.

Abstract
| Pages: 24-32
The structural, electronic, elastic, mechanical and thermal properties of transition metal aluminides (CoAl, NiAl and RuAl) have been investigated systematically using first principle density functional theory (DFT). Ground state properties such as lattice constant (a0), bulk modulus (B) and its pressure derivative (B′) are calculated which show well agreement with the experimental and other theoretical results. The electronic properties have been analyzed quantitatively. The values of elastic constants are also reported. The ductility of these compounds has been analyzed using the Pugh’s rule, Cauchy’s pressure (C12-C44) and electronic structure. Our calculated results indicate that NiAl is ductile while CoAl and RuAl are brittle. The elastic properties such as Young's modulus (E), Poisson's ratio (σ) and anisotropic ratio (A) are also reported. We have also correlated the ductility and bonding behaviour of these compounds.

Abstract
| Pages: 31-35
A piezoelectric thin film sandwiched between two metal electrodes is basic structure for high frequency bulk acoustic wave devices. For that propose, the RF magnetron sputtering deposition for piezoelectric ZnO film formation and its such application for film bulk acoustic resonator (FBAR) devices are presented. Several critical parameters of the RF magnetron sputtering process deposition pressure, RF power, substrate temperature, O2 concentration and the target to substrate distance were determined to clarify their effects on the material characteristics of the ZnO. Highly c-axis oriented thin films as thick as 5.7 μm were grown and analyzed. Compressive stresses were observed. The FBAR devices with the ZnO films exhibited a pronounced resonance peak centred at 537 MHz with a k2 coupling coefficient of 7 %. It found therefore that the impedance matching of the FBAR could be easily achieved simply by controlling the resonance the resonator.

Abstract
| Pages: 58-75
In this paper some microphysical and optical properties of urban aerosols were extracted from OPAC to determine the effect of hygroscopic growth at the spectral range of 0.25μm to 2.5μm and eight relative humidities (RHs) (0, 50, 70, 80, 90, 95, 98, and 99%). The microphysical properties extracted were radii, volume mix ratio, number mix ratio and mass mix ratio as a function of RH while the optical properties are scattering and absorption coefficients and asymmetric parameters. Using the microphysical properties, growth factors of the mixtures were determined while using optical properties we determined the enhancement parameters and were then parameterized using some models. We observed that the data fitted the models very well. The angstrom coefficients which determined the particles’ sizes distribution increases with the increase in RHs except at the delinquent point where it decreases with the increase in RHs. The mixture was determined to have bimodal type of distribution with the dominance of fine mode particles.

Determining the quality of the hazy image is difficult problem, thus these images need to analyzing after determined the quality or dehazing. In this paper, we analyzed the hazy(by the dust) images depending on YIQ color space. First we designed the system captured images which graded for high to very low hazy (by adding the dust) by using HeNe laser, in these images we calculated the Normalize Mean Square error (NMSE) for each components in YIQ and RGB color space, and the basic components in the Structure Similarity Index (SSIM) are (contrast, structure and luminance) moreover the mean for all has been calculated. We can see the lightness (in YIQ) and luminance ( in SSIM) component are not effected by the dust whereas the chromatic components are highly effected by the dust.

High Temperature Electronic Properties of a Microwave Frequency Sensor – GaN Schottky Diode

Author(s):

Michael Olusope Alade


Abstract
| Pages: 47-53
The potential energy barrier height, depletion layer thickness and junction capacitance properties of a microstructure GaN Schottky diode as a microwave frequency sensor have been estimated at extreme temperature (300 – 950K), under applied external bias (0 – 20V) by computational method based on the analytical expression obtained by the application of rule of thumb on the existing energy gap of n-GaN and existing solutions (depletion thickness and capacitance) of Poisson’s equation. The results of the calculation shown that the barrier height decreases as the temperature increases, but abrupt increase in the barrier height was observed as the temperature continues to increase above 900K. This behaviour may be linked to thermal stability demonstrated by n-GaN Schottky diode at high temperature. Also, the depletion thickness decreases as the temperature increases and the capacitance decreases as the bias increases. The decrease of the capacitance is much at high temperature under the same applied bias condition. The GaN Schottky diode can be employed as microwaves frequency sensor at very high temperature.

Today, cell phone technology is an integral part of everyday life and its use is not only restricted to voice conversations but also conveying news, high resolution pictures and internet. As the number of mobile phone usage increased exponentially nowadays, issues related to the electromagnetic radiation produce by mobile phone is becoming a big concern in the society. Mobile phone produced electromagnetic waves and when placed near the ear skull, will produce electromagnetic radiation so called thermal effect. The transfer of electromagnetic field to the body producing thermal effect leads to heating of body tissue at specific rate. This effect is differ depending on the period of time the mobile phone being used and type of mobile phone. This paper discussed on the result of thermal distribution generated by handheld mobile phone towards human head via collection of image from thermal imaging camera. The analysis is conducted in an anechoic chamber with average of 45 minutes talking hour with two different types of mobile phone, internal and external antenna serving different radio frequency range, 900 MHz and 1800 MHz . The results showed an increased of heat especially at the place near the ear skull after 45 minutes of operation. When comparing both different types of mobile phone, mobile phone with external antenna produce more heat compared to mobile phone with internal antenna.

Abstract

The aim of this study is to investigate the dynamic mechanical characteristics of HIV/AIDS in the human blood circulating system. In this work, we developed a constitutive carrier wave equation which we used as a solution to a second-order differential equation. It seems from the results, that the physical dynamic components of the HIV responsible for their destructive tendency are bl , n¢l , e ¢l and k ¢l with l as a raising multiplier, whose physical range of interest is 0 £ l £ 19332. It is established in this study that when the HIV enters the human blood circulating system, it takes about 73 days before its absolute effects would begin to manifest. This study revealed that AIDS actually results when these destructive dynamic components of the HIV gradually become equal to their corresponding active dynamic components in the human blood circulating system. This is when 19234 £ l £ 19332and the time it takes the HIV infection to degenerate to AIDS is about 8years (96months). The constitutive carrier wave equation that describes the biological system of man finally goes to zero - a phenomenon called death, when the multiplier approaches the critical value of 19332 and the time it takes to attain this value is about 12 years (144 months).

Abstract
| Pages: 36-43
In this study, we analyse the effects of thermal radiation on unsteady natural convective flow of a nanofluid past an impulsively started infinite vertical plate. The nanofluid contains heat treatable nickel chromium iron alloy (Nimonic 80A) nanoparticles with Ethylene Glycol as base fluid. The partial differential equations governing the flow are solved numerically by MATALB pde solver package. The effects of various parameters on velocity and temperature profiles, as well as Nusselt number and Skin friction coefficient are examined and presented graphically .It is found that rate of heat transfer increases by increase in thermal radiation and change of particle shape. Also we observed that the decrease in radiation parameter leads to fall the value of skin friction coefficient. Shape of nanoparticles doesn’t effects velocity of the fluid.

Using the microphysical properties, hygroscopic growth factors of the mixtures were determined while using optical depths we determined the Angstrom coefficients, enhancement parameters and the relationship between optical depth and RHs. The growth factors and the enhancement parameters were then parameterized using some models to determine their relationships with RHs. The data fitted the models very well. The angstrom coefficients show that the mixture have bimodal type of distribution with the dominance of fine mode particles and the mode sizes increase with the increase in RH and soot and water soluble concentrations.

The solution of Schrodinger equations for q-deformed modified Poschl-Teller and hyperbolic Scarf II potentials are investigated using Nikiforov-Uvarov method and a mapping method. By applying a translation of spatial variable non-deformed potentials are mapped on to deformed potential or vice versa and as a product the potential’s parameters scaling obtained. The bound state energy spectra obtained using NU method are given in the close form and the corresponding wave functions are formulated in terms of the Jacobi Polynomials. The energy spectra and the radial wave functions of the system are also produced by a mapping using potential’s parameters scaling from the non-deformed to the deformed potential.

Abstract
| Pages: 54-60
The coexistent of superconductivity (SC) with antiferromagnetism (AFM) and ferromagnetism (FM) as U →∞ is studied in CeCu2Si2 on application of the Exact Diagonalization technique to the Single site Impurity Anderson Model and the Periodic Anderson Model. The results obtained show that magnetic instability is the key to understanding superconductivity in Heavy Fermion compounds as increasing the onsite coulomb repulsion, U, suppresses all ferromagnetic tendencies and enhances superconductivity. The results obtained here is in qualitative agreement with the inelastic neutron scattering experimental results obtained by Stockert et al (2011) on increasing the copper content in CeCu2Si2. U in this theoretical study behaves as Cu in the inelastic neutron scattering experiment.

Abstract
| Pages: 38-48
Microwave and Millimeter wave integrated circuits (MICs) have experienced a tremendous growth over the last 50 years. Microstrip line is one of the popular lines in these MICs. Due to the layout necessities, an electromagnetic wave that propagates down a microstrip line may encounter discontinuities such as T-junctions, Bends and vias. A simulation model is presented here for analysing these discontinuities in microstrips through Sonnet Software. The parameters of microstrip lines are determined from the empirical formulae which are based on full wave analysis. The simulation work has been performed on Alumina substrate. The discontinuities are simulated and compensated which gives important results for designing high frequency microwave circuits.

Abstract
| Pages: 54-58
The design of future-generation mobile communication systems depends critically on the pathloss prediction methods and their suitability to various signal propagation regions. An accurate estimation of radio pathloss is useful for predicting coverage areas of base stations, frequency assignments, determination of electric field strength, interference analysis, handover optimization, and power level adjustment. The radio path loss will also affect other elements such as the required receiver sensitivity, the form of transmission used and several other factors. As a result, it is necessary to understand the reasons for radio path loss, and to be able to determine the levels of the signal loss for a given radio path. In this paper, we investigated the radio signal path attenuation behavior, by conducting an experimental measurement survey in a UMTS network transmitting at 2100MHz band in Government Reservation Area (GRA), Benin City. The measured field strength data collected at various distances from the base stations was used to estimate the pathloss. Firstly, the effect of different parameters, such as distance from base stations was studied and it is observed that path loss increases with distance from the signal source due to a corresponding decrease in field strength. Secondly, the calculated pathloss data have been compared with data from other existing pathloss prediction methods. We find that the Okumura-Hata model pathloss values were closest of all the propagation models considered classifying the environment into consideration. Thus, the performance of Okumura-Hata model shows its suitability for path attenuation loss prediction in UMTS networks in GRA.

The structural, electronic, elastic, optical and thermodynamical properties of the ordered SiGe, SiSn and GeSn cubic alloy in zinc-blende (B3) structure are investigated using the plane-wave ultrasoft pseudopotential based on the first principles density functional theory (DFT).The ground state properties such as the lattice parameter, bulk modulus, energy derivative, elastic constants Cij, Young’s modulus, Poisson’s ratio and the Zener anisotropy factor were calculated. The results are in favorable agreement with a previous work. The complex dielectric function, refractive index, extinction coefficient, complex conductivity function, energy loss spectrum, absorption coefficient and optical reflectivity were calculated and the peak position distributions of imaginary parts of the complex dielectric function are explained. The calculated elastic properties are consistent with other calculated results and predicted the Debye temperature, the isochoric heat capacity, the entropy, enthalpy and free energy.

Nanocomposites are used in many industries such: solar cells, light emitting diodes, optoelectronic device, aircraft and cars. This paper is aimed to preparation of (PVA-CNTs) nanocomposites to using the new materials in many industries. Using the nanocomposites in these applications need to study the electrical, optical and mechanical properties which investigated in this paper. The samples of nanocomposites are prepared by using casting technique with different concentrations of carbon nanotubes. The optical properties of nanocomposites are measured in the wavelength range (200-800) nm. The results showed that the absorption coefficient, extinction coefficient, refractive index and real and imaginary dielectric constant of nanocomposites are increasing with increase the carbon nanotubes concentrations.

The results found the electrical conductivity is increased with increasing the carbon nanotubes concentration and temperature. The activation energy is decrease with increasing the weight percentages of carbon nanotubes. Also, the mechanical properties of (PVA-CNTs) are investigated. Results showed that velocity of ultrasonic wave, specific acoustic impedance, bulk modulus and compressibility change with increase the concentration of carbon nanotubes.

Author(s):

A. K. Borah -- P. K. Singh -- P. Goswami


Abstract
| Pages: 75-87
This paper deals main physical processes arising during phase change have been investigated. The heat exchange within a single phase, many engineering technologies involve multiphase systems. Hence the problems dealing with phase change is the movement of phase interface with the release with the absorption of latent heat at this interface. The problems are highly nonlinear and thermophysical properties are typically different on each side of the phase interface. Therefore, analytical solutions are available only for a limited class of one-dimensional problems- pure materials or fluids in infinite or semi-infinite domains. In the present paper we demonstrate phase change heat transfer in pure liquids and materials as well as multicomponent systems. The multiphase systems have (i.e., solid, liquid, or gas phase) including one or more components. Although the governing equations vary for each type of multiphase system (i.e solidliquid, liquid-gas, etc.,), the overall features of the physical and mathematical models are analogous. Theses continuum models are based on a mixture formulation or an interface tracking formulation. In the mixture approach, the control volume consists of a homogeneous mixture encompassing both (or all) phases. Mixture of interface tracking formulations are demonstrated in this studies.

Superexchange Driven Singlet-Triplet Transition in Quantum Dots Array Embedded in Kagome Lattice System

Author(s):

Godfrey E. Akpojotor


Abstract
| Pages: 69-77
The envisaged revolutionary impact of the quantum computer has continued to elucidate diverse means to design and build physical quantum computers. In condensed matter physics, one of the means is to design materials to host twoelectron quantum dots (QDs) which can be manipulated into singlet-triplet (S-T) transition. This transition which is read as the quantum bits (qubits) that is considered as a possible logic gate for the quantum computers is enhanced by external magnetic field which is a potential source of decohenrence. In the study here therefore, the possibility of using a superexchange induced internal magnetic field to drive the S-T transition in QDs embedded in a kagome lattice system (KLS) is examined. The design is by embedding the two-electron QDs into the frustrated sites of the KLS and then filling the other sites with single electrons. The parameter space of this KLS to achieve the S-T in the QDs array are obtained from the superexchange interaction in correlated variational study of the system.

Abstract
| Pages: 49-53
The ab-initio calculations were performed to investigate structural, electronic, thermal and elastic properties of the binary ductile intermetallic compounds PdSc and PtSc with B2 (CsCl-type) structure using full potential linear augmented plane wave method (FP-LAPW) on the basis of density functional theory (DFT).The generalized gradient approximation (PBE-GGA and WC-GGA) is applied for PdSc and PtSc. The calculated equilibrium properties such as lattice constant (a0), bulk modulus (B) and its first derivative (B') are in better agreement with experimental and theoretical results. The elastic constants (C11, C12 and C44) of these compounds are reported first time. The value of B/GH ratio for both the compounds are larger than 1.75, indicating the ductile manner of these materials. From density of states and Band structure, it is observed that these intermetallic compounds are metallic in nature. We report first time mechanical and thermal properties which are predicted from the calculated values of elastic constants.

Topology of Charge Density from Pseudopotential Density Functional Theory Calculations

Author(s):

Nawzat Saeed Saadi


Abstract
| Pages: 92-104
The absence of core electrons in pseudopotential electronic structure calculations poses some important problems on determining the topology of density. The key feature of valence-only densities is the lack of critical points (CPs) at the nuclear positions affected by core removal, which are sometimes substituted by local minimum CPs, the substitution of a maximum by a minimum must be necessarily accompanied by the creation of other compensating CPs, including at least either one maximum or one ring CP. As density is relatively unaffected at distance points far enough the removed cores, these new CPs are expected to lie in the proximity of the latter, and the topology of density to closely resemble that of the AE density in the chemically relevant valence regions. This difficulty is well-known in literature, and several works have been devoted to elucidate how to bypass it (Cioslowski and Piskorz, 1996). The correct topologies may be obtained from corereconstructed pseudo-AE densities. This paper will show how the correct topology can be obtained from pseudopotential calculations. In order to analyze the problems that arise from the core electrons, results obtained for Alanine (CH3CH (NH2) COOH), Aminophenol (C6H4 (OH) NH2), Ethene (C2H4), and Propanone ((CH3)2CO) using all-electron, pseudo-valence wavefunctions are reported.

Abstract
| Pages: 80-92
Negative dispersion curves in a typical type of high negative chromatic dispersion photonic crystal fiber(PCF) have been investigated in this paper. The depended class of (PCF) has double-core structure (coreregion: which has inner core and outer core) with a honeycomb photonic lattice in the cladding region. Negative dispersion curves deviated from core-region of this type of fibers will be investigated. The investigation has depended an estimation process using an approximation function to create a mathematical model that enables us to measure negative dispersion curves. The influence of inner-core parameters (dcore d1 and d2) on dispersion curves has been investigated by varying the values of these parameters. Negative dispersion curves that were introduced by a previous study using finite-difference frequency-domain (FDFD)method for this class of(PCFs) are directly included in this work in order to measure matching ratio with our results. Gaussian approximation function has been considered to estimate our mathematical model.

Phase Transformation and Volume Collapse of SmBi under High Pressure

Author(s):

Faisal Shareef M. -- Sadhna Singh


Abstract
| Pages: 54-57
The present study reveals the high pressure phase transition and associated volume collapse of SmBi which crystallize in NaCl (B1) structure. To achieve the goal we have used the modified three body interaction potential model (TBIPM) which is applying probably the first time for any compounds in high pressure model study. These interactions arise due to the electron shell deformation of the overlapping ions in the crystals. During phase transition there is an intermediate tetragonal phase which can be viewed as distorted CsCl (B2) structure and finally it transforms to CsCl (B2) phase. The values of phase transition pressure and associated volume collapse estimated by us are found to be well suited with experimental values. Thus our modified TBIPM is in good agreement with available measured data of SmBi.

Half-metallicity in EuN: A First-Principles Calculation

Author(s):

Mona A. Huleil -- Samy H. Aly -- Sherif Z. Yehia -- M. Fadly


Abstract
| Pages: 93-98
We report on the electronic and magnetic properties of the rock salt (RS) and cesium chloride (CsCl) phases of EuN. Our calculation was performed within the framework of the density functional theory (DFT), as implemented in the Wien2k package. We have used the generalized gradient approximation (GGA) for the exchange correlation potential and, in certain, cases the Local Spin Density (LSDA) approximation, with the Hubbard interaction taken into account. Our calculation demonstrates the presence of an energy gap in both of the RS and CsCl structures when only spin-polarized calculation is used. However, taking the Hubbard potential into consideration, via the LSDA+U scheme, led to the disappearance of the energy gap, and hence to the absence of the half-metallic behavior in this system.

Author(s):

Ahmad Hussain -- Dheya Al-Othmany


Abstract
| Pages: 79-89
There are a number of liquid processes and waste streams at nuclear facilities (i.e. nuclear power plants, fuel reprocessing plants, nuclear research centers, etc.) that require treatment for process chemistry control reasons and/or the removal of radioactive contaminants. These processes may be for reactor primary coolants, the cleanup of spent fuel pools, liquid radioactive waste management systems, etc. One of the most common treatment methods for such aqueous streams is the use of ion exchange, which is a well developed technique that has been employed for many years in both the nuclear industry and in other industries. Nuclear power plant process water systems have typically used organic ion exchange resins to control system chemistry to minimize corrosion or the degradation of system components and to remove radioactive contaminants. Organic resins are also used in a number of chemical decontamination or cleaning processes for the regeneration of process water by reagents and for radionuclide removal. In this report we will describe the method to solidify this waste by cementization techniques methods. There are several techniques are available for treating and conditioning of ion exchange resins. One of such technique uses a matrix material, which can be used in the conditioning process. There is wide rang of potential materials available for the conditioning of low and intermediate level liquid wastes and at the end we will mechanically (compression strength) testify these cubes of different cement and resin composition, according to IAEA standards.

Abstract
| Pages: 58-62
The electronic, elastic and thermal properties of RECd (RE =La, Ce and Pr) intermetallic compounds crystallizing in B2-type structure have been studied using first principles density functional theory within generalized gradient approximation (GGA), and the local spin density approximation (LSDA) for the exchange correlation potential. From energy band structure and density of states we found that these intermetallics are metallic in nature. The thermal and mechanical properties are predicted from the calculated values of elastic constants. The ductility of these compounds is determined by calculating the bulk to shear ratio B/GH. Our calculated results indicate that PrCd is most ductile amongst all the RECd compounds. To the best of our knowledge this is the first theoretical prediction of the elastic properties of these compounds.

Relationship between earthquake fault triggering and societal behavior using ant colony optimization

O P Mishra -- P K Dutta -- M.K. Naskar


Abstract
| Pages: 99-108
In this analysis, we use the ant behaviour in simulating a framework for analysis of complex interplay amongst short time-scale deformation, long time- scale tectonics for positive stress coupling and slip interactions in earthquake genesis modeling. Using the proposed improved ant colony algorithm for global optimization the best solution ants within the search and the circulation of the optimal solution as the initial solution search, to expand its search, to avoid falling into local optimum of trigger zones analysis for earthquake occurrences. In order to validate the avalanche behaviour and corresponding nucleation we best solution as the initial solution is adopted in order to widen searching scope to avoid getting into local optimum . In this proposed framework, an ant colony model is simulated to identify the physical framework of identifying trigger basins for the precursors to geodynamic model of propagation for precursory stress-strain signals. The disturbances at trigger basins cause the collapse of a subsystem leading to stress evolution and slip nucleation. Trigger basins help identify the zone of earthquake source nucleation as an index of α and μ for strain analysis. The stress strain network can be interpreted by the increase in steady-state energy transmitted due to redistribution of stress accumulation into the earth tectonic framework. Sand pile behaviour model has been modeled through ant colony optimization for forecasting of likelihood time of triggering influences of lithosphere on the basis of critical zones of lithosphere where dump of elastic pressure is possible. The ant colony adaptive framework consisted of vertices representing the stress-strain component and edges, representing scored transformations for global coupling effects have been constructed for dynamic monitoring of stress and strain behaviour. Triggering basins serve as harbingers of large earthquake where stress-strain interactions have been analyzed by the quasi-static mechanics of seismic precursory stress-strain propagation in the crustal lithosphere. The study shows that dynamic variation of stress drop due to saved up pressure can be modeled by ant colony framework for steady state release due to trigger and global correlation framework. The simulation framework shows that with time, spatial triggering points can be negatively coupled and these interact with lesser impact, while positive coupling occurs only with more distant zones of stress generation for geodynamic frameworks, suggesting that the structural heterogeneities within the causative rocks associated with cracks and pores can dictate the pattern of stress – strain interactions and earthquake generating processes.

Jagdish Pataiya -- Chandrabhan Makode -- A. Singh -- Mahendra Aynyas -- Sankar P. Sanyal


Abstract
| Pages: 63-66
We have examined the pressure induced structural and electronic properties of neptunium monobismuthides. The total energy as a function of volume is obtained by means of self-consistent tight binding linear muffin-tinorbital (TB-LMTO) method within the local density approximation (LDA). It is found that NpBi is stable in NaCl – type structure under ambient pressure. We predict a structural phase transition from NaCl-type (B1-phase) sructure to CsCl-type (B2-phase) structure for NpBi in the pressure range of 11 GPa. We also calculate the lattice parameter (a0), bulk modulus (B0), band structure and density of states. From energy band diagram it is observed that NpBi exhibit metallic behaviour. The calculated equilibrium lattice parameters and bulk modulus are in general good agreement with available experimental data.

Abstract
| Pages: 120-128
The presence of natural radioactivity in brick and other building materials results in internal and external exposure to the general public. Therefore, it is desirable to determine the concentration of naturally occurring radionuclides. Bricks are one of the main components in building construction beside cements, granites and sand. Thus, this research has been carried out in order to investigate the levels of natural radioactivity and associated radiation hazard in Algerian red brick. The natural radioactivity due to the presence of 226Ra, 232Th and 40K in brick samples used as building materials in Tlemcen province - Algeria was measured by gamma spectrometry using NaI(Tl) scintillation well-shaped detector. In this context, brick samples were collected from two manufactories Tafna and Tounan. The mean values of activity concentrations for 226Ra, 232Th and 40K were found to be in the main value of 15.5Bq.kg-1, 11Bq.kg-1, and 196.5Bq.kg-1, respectively. The concentrations of these natural radionuclides were compared with the reported data for other countries and were found significantly lower than the world wide average (1,2). Radium equivalent activities were calculated (41.3 to 51.4) Bq.kg–1 for the analyzed samples to assess the radiation hazards arising due to the presence of these radionuclides in the samples. The calculated radium equivalent activities are lower than the limit set by the OECD report 370 Bq.kg–1 (3). The measured representative level index values for the investigated samples varied in the range (0.31 to 0.38) Bq.kg1. External and internal hazard index (Hex,Hin), the specific dose rates in door (D) and the annual effective dose (DE) due to gamma radiation from building materials was calculated.

Abstract
| Pages: 109-128
We analyze the effects of radiation and chemical reaction on MHD boundary layer flow over a moving vertical porous plate with heat source. The partial differential equations governing the flow are solved numerically using the shooting technique. The influence of various parameters on velocity, temperature and concentration profiles, as well as Nusselt number and skin-friction coefficient are examined and presented graphically and through tables. We observed that rate of heat transfer are more influenced by radiation and chemical reaction parameters.

Abstract
| Pages: 67-72
First principles study of structural, electronic, elastic and mechanical properties of ferromagnetic GdSn3 and nonmagnetic YbSn3 rare-earth intermetallics, which crystallize in AuCu3-type structure, is performed using density functional theory based on full potential linearized augmented plane wave (FP-LAPW) method. The ground state calculations are carried out within PBE-GGA, PBE-sol GGA and LSDA approximations for the exchange correlation potential. The calculated ground state properties such as lattice constants and bulk moduli agree well with the experiment as well as other theoretical results. We report elastic constants for these compounds for the first time. Both these compounds are found to be ductile in nature. The computed electronic band structures show metallic character. We also report mechanical properties of these compounds for the first time.

Jyotsna Chauhan -- Gargi bhattacharya


Abstract
| Pages: 73-77
Chlorothalonil (2,4,5,6-tetrachloroisophthalonitrile) is a polychlorinated aromatic mainly used as a broad spectrum, contact fungicide. A rational approach to test these fungicides is to know the three dimensional structure of these compounds and macromolecular receptor sites as well as their molecular complex .The structures of these compounds can be obtained by X-ray diffraction method in crystalline form and they will invariably be similar to their structure in solutions. The activity of fungicides is intimately related to its chemical structure. Knowledge about the chemical structure of a chemical is useful for the synthesis of new compounds with more specific actions and fewer adverse reactions, to increase/decrease the duration of action of the original drug or to get a more potent compound, to restrict the action to a specific system of the body and to reduce the adverse reactions, toxicity and other disadvantages associated. We can understand the basic chemical groups responsible for drug action. Recently it has been observed that some of the fungicides are losing their effects. So analogous compounds can be designed as substitute, if their structures are known

Madhu Sarwan -- Bashir Ahmed Mir -- Faisal Shareef M -- Vasudev Thakre -- Sadhna Singh


Abstract
| Pages: 78-82
The structural phase transition, volume collapse and second order elastic constants of 5d-transition metal mononitride (IrN) have been investigated by using interaction potential model (IPM) which consists of Coulomb interaction, three-body interaction and short range overlap repulsive interactions. The present theoretical approach has predicted pressure-volume relationship curves which shows that IrN exhibits a zinc-blend (ZB) type structure at an ambient pressure and undergoes a structural phase transition from B3 to B1 phase at pressure 72 GPa. The equation of state shows volume collapse of 9.09 %. The phase transition pressure and associated volume collapses obtained from this model show a reasonable agreement with other theoretical results. The second order elastic constants are also investigated for ZB phase.

Mani Shugani -- Sunil Singh Chouhan -- Mahendra Aynyas -- S. P. Sanyal


Abstract
| Pages: 83-89
First principles density functional calculations were performed to study the structural, electronic, elastic and mechanical properties of erbium copper intermetallic compound (ErCu). The calculations are carried out within the generalized gradient approximation (GGA) for the exchange and correlation potential. The total energy as a function of volume is obtained by performing spin-polarized calculation. Magnetically the ErCu compound is stable in ferromagnetic (FM) state and its crystal structure is CsCl-type. Ground state properties such as lattice constant (a0), bulk modulus (B), its pressure derivative (B′) and magnetic moment (μB) are calculated. The density of states at the Fermi level, N(EF) and specific heat coefficient are also estimated in majority and minority spin channels. The electronic properties such as band structure and density of states (DOS) reveal that no band gap lead to metallic character of ErCu. The elastic constants (C11, C12 and C44) and mechanical properties such as Poisson’s ratio (σ ), Young’s modulus (E), shear modulus (GH), anisotropic factor (A) are also calculated . Ductility for these compounds is further analyzed by calculating the ratio of (B/GH ) and Cauchy pressure (C12 - C44).

Abstract
| Pages: 90-93
In the present paper, we have investigated the high-pressure structural phase transition of rare-earth antimonide. We studied theoretically the structural properties of this compound (DySb) by using the three-body potential model with the effect of electronic polarizability (TBIPEP). These compounds exhibits first order crystallographic phase transition from NaCl (B1) to CsCl (B2) phase at 22.6 GPa respectively. The phase transition pressures and associated volume collapse obtained from present potential model(TBIPEP) show a good agreement with available experimental data.

Abstract
| Pages: 94-96
We have applied an Extended Three Body Force Shell Model (ETSM) by incorporating the effect of translational- rotational coupling for the investigation of thermoelastic properties such as cohesive energy( ,  molecular force constant(f), compressibility(β), Restrahlen frequency ( ), Debye temperature (θD), Gruneisen parameter (γ), second Gruneisen parameter (q), Moelwyn Hughes constants (F1), and ratio of volume expansion coefficient (αv) to volume specific heat (cv ) of superoxide materials NaO2 and KO2 at 300K. Besides this we have calculated static shear modulii (c44). The shear modulii computed between the temperatures ranges 50K to 500K. Here, we could compare our result with experimental data for thermal properties only at room temperature and the magnitudes of SOECs seem to be correct, also the ETSM method produces the sign of SOECs correctly.

We have studied geomagnetic storm (Dst≤-150 nT), associated with Coronal Mass Ejections (CMEs), observed during the period of 2000-2011 with Interplanetary Magnetic Fields. It is observed that coronal mass ejections (CMEs) related geomagnetic storms are found to be association rates of halo and partial halo CMEs are 18(90%) and 02(10%) respectively. From the further analysis, positive co-relation has been found between magnitude of CMEs related geomagnetic storms and speed of coronal mass ejections (CMEs), with correlation coefficient 0.50. Positive co-relation has been found between magnitude of CMEs related geomagnetic storms and magnitude of change in interplanetary magnetic fields, with correlation coefficient 0.55, positive co-relation has been found between magnitude of CMEs related geomagnetic storms and peak value of change in interplanetary magnetic fields, with correlation coefficient 0.56.

Abstract
| Pages: 101-104
Nanocrystalline (Pb1-xBix)S thin films were successfully deposited on suitably cleaned glass substrate at constant room temperature, using the chemical bath deposition technique. After deposition the films were also annealed at 4000C for 1 hour in air. The crystal structures of the films were determined by X-ray diffraction studies. The films are adherent to the substrate and well crystallized according to cubic structure with the preferential orientation (200). The crystallite size of the pure PbS thin films at optimized deposition time 30 min was found to be 40.4 nm, which increased with Bi content in pure nanocrystalline PbS thin films. The surface roughness of the films was measured by AFM studies. Experiments showed that the growth parameters, doping and annealing influenced the crystal structure of the films.

Specific heat and Thermodynamics of Titanate Perovskite Materials

Author(s):

Renu Choithrani -- N. K. Gaur


Abstract
| Pages: 105-108
Specific heat and thermodynamical properties of the LaTiO3+δ/2 have been investigated for the first time using extended rigid ion model (ERIM). With the increase of nominal hole doping δ, the system undergoes a phase change from an insulating phase to a metallic phase at δc IM = 0.05 and the low-temperature antiferromagnetic phase disappears at δc mag = 0.08. LaTiO3+δ/2 has been suggested to have promising scientific and technological applications. Our computed specific heat results follow the same trends of variation with corresponding experimental data. The values of specific heats also increase with temperature. The theoretically computed thermodynamical properties of LaTiO3+δ/2 compound are in good agreement with the available experimental results.

Structural Analysis and Elastic Behaviour in CEN with NaCl– type Structure

Author(s):

Ritu Dubey -- Sadhna Singh


Abstract
| Pages: 109-112
we have expressed the Gibbs free energy for CeN compound as a function of pressure and charge transfer though improved interaction potential model (IIPM). The lattice energy in it has been represented by an IIPM consisting of the long range coulomb interaction, three body interaction, polarizability effect and overlap repulsive interaction effective up to the second neighbour ions. Using this approach high pressure phase transition phenomena in CeN have been explored. The phase transition pressure, volume collapse and elastic properties for CeN predicted from this approach are found to be the experimental data in future. This shows that the inclusion of three body interaction effects and polarizability effects makes the present model suitable for high pressure studies. Moreover, the elastic properties of CeN are also investigated.

Abstract
| Pages: 118-121
The dual frequency Global Positioning System (GPS) receiver provides an opportunity to determine Total Electron Content (TEC) over the crest of equatorial ionization anomaly region Bhopal by taking advantage of the dispersive nature of the ionospheric medium. The TEC values observed for the geomagnetic storm of the January 2005 is used in this paper to discuss the behaviour of ionospheric total electron content (TEC) during geomagnetically disturbed period. Variation of TEC is studied in correlation with the geomagnetic index Dst and southward component of interplanetary magnetic field Bz. The TEC variability is found to vary between with the maximum negative excursion of Dst index during the geomagnetic storms days. Positive phase is observed. Maximum TEC variability is observed during the recovery phase of the storms. Electron and ion density measurements from the DEMETER satellite are compared with the TEC measurements. The study of storm time TEC behaviour is very important due to recent increase in satellite-based navigation applications.

Effect of Magnetic activity on scintillation at Equatorial Region during Low Solar Activity

Author(s):

Sunita Tiwari -- Shivalika Sarkar -- Asha Vishwakarma -- A. K. Gwal


Abstract
| Pages: 122-129
Single and dual frequency GPS receivers used in low-latitude regions can suffer from rapid amplitude and phase fluctuations known as scintillation. Intense signal fluctuations cause GPS receivers to stop tracking the signals from GPS satellites in a process sometimes called “loss of lock”. This may increase navigation errors or, in some cases, cause navigation failure. Data recorded from ground-based GPS scintillation monitors (GSV 4004A GPS receiver) installed at the Space Science Laboratory, Department of Physics, Barkatullah University, Bhopal (23.2ºN, 77.4ºE; Geomagnetic 14.2ºN) are used. Different phases of geomagnetic storms affect the generation and development of ionospheric irregularities differently. Results shows that occurrence of scintillation observed during summer months are relatively weak as compared to those recorded during winter and equinox months. The enhancement in magnetic activity leads to a suppression of pre-midnight scintillations during the equinox and during the winter, whereas as enhancement is observed in summer months. The generation or inhibition of irregularities during the main phase/recovery phase of a magnetic storm depends upon the location of the station and local time.

Abstract
| Pages: 130-134
The study of perovskite manganites La0.67Sr0.33Mn1-xCrxO3 (0≤ x ≥0.10) has been carried out. The structure and magneto-transport properties of La0.67Sr0.33Mn1-xCrxO3 manganites are strongly dependent on the doping level x. Polycrystalline samples of La0.67Sr0.33Mn1-xCrxO3 (0≤ x ≥0.10) were prepared by solid state reaction method. The little difference between the ionic radii of Cr3+ and Mn3+ causes no change in the structure, the structure remains rhombohedral. The temperature dependence of the resistivity is measured from 5 – 400 K without and with magnetic field upto 5 T. The value of metal-insulator (M-I) transition temperature (TP) decreases when resistivity increases for all the samples while doping level x increases. The value of magnetoresistance (MR %) increases with increases Cr doping level for all samples. We have calculated energy band gap (Eg) for all samples and it is revealed that as per doping level increases Eg increases which is comparable with experimental data. So, the structure and magneto-transport behavior pretentious by Cr doping.

Abstract
| Pages: 149-153
The electronic, elastic and thermal properties of RECd (RE =La, Ce and Pr) intermetallic compounds crystallizing in B2-type structure have been studied using first principles density functional theory within generalized gradient approximation (GGA), and the local spin density approximation (LSDA) for the exchange correlation potential. From energy band structure and density of states we found that these intermetallics are metallic in nature. The thermal and mechanical properties are predicted from the calculated values of elastic constants. The ductility of these compounds is determined by calculating the bulk to shear ratio B/GH. Our calculated results indicate that PrCd is most ductile amongst all the RECd compounds. To the best of our knowledge this is the first theoretical prediction of the elastic properties of these compounds.
