Abstract
| Pages: 1-5
In general sense, education is form of learning in which there is transfer of knowledge, skills and attitude from generation to generation by the means of teaching, training, research, or by self-directed learning. (Dewey, 1916/1944)The word teaching is defined in Oxford dictionary as ‘’ to impart knowledge to or instruct (someone) as to how to do something’’.  Dolmens defines learning as a collaborative, constructive, contextual and self directed process. (Dolmans et al., 2005)Large group teaching is a commonly utilized methods deployed for imparting quality teaching. With the use of lectures, efficient transfer of knowledge and concepts can be ensured. The main objective behind using Large group teaching has been to achieve better student understanding of concepts and help them acquire the core subject knowledge; give them a direction for self-directed learning. Better motivation of student is known to have positive impact upon their desire to learn. 4Medical education has been known to utilize LECTURES and LARGE GROUP TEACHING methods for undergraduate/postgraduate teaching. Imparting core knowledge of new concepts in life sciences can be tough for new learners as well as the conventional teacher. Lectures constitute an efficient means for achieving the curriculum aims and objectives.A good learning experience may depend upon involvement of students by problem solving practices, learning activities during sessions to motivate deep subject learning rather than just have superficial or strategic knowledge base or an achieving type only.

Abstract
| Pages: 6-13
The fully sequenced genomes of five species within the Saccharomyces sensustricto complex provided a wealth of information for molecular-evolutionary inference. Yet virtually little thing was known about population-genetic variation within these species, including the molecular-biological and genetic-model organism S. cerevisiae. Here we investigated the population genetic variation and population structure of S. cerevisiae by analyzing the sequence of the MF(alpha)1 loci in 41 strains. Sequence analysis demonstrated a distinct population structure in S. cerevisiae, distinguishing strain collected from Kunming grape juice and other strains. Our findings indicated that strains clustered together might mainly due to ecological rather than geographic factors.

Tuned Simulated Annealing Based on Boltzmann and Bose-Einstein Distribution Applied to Maxsat Problem

Author(s):Juan Frausto-Solis

Abstract
| Pages: 14-26
In this paper, a hybrid Simulated Annealing algorithm using Boltzmann and Bose-Einstein Distributions (SABBE) is proposed. SABBE was designed for solving satisfiability (SAT) instances, and it has three phases: i) BP (Boltzmann Phase), ii) BEP (Bose-Einstein Phase), and iii) DEP (Dynamical Equilibrium Phase). BP and BEP are simulated annealing searching procedures based on Boltzmann and Bose-Einstein distributions respectively. BP ranges from high to low temperature values, while BEP goes from low to very low temperatures. Another simulated annealing search procedure, DEP, is applied at the final temperature of the second phase. However, DEP uses a particular heuristic for detection of stochastic equilibrium by employing a least squares method during its execution. Finally, SABBE parameters are tuned with an analytical method, which considers the maximal and minimal deterioration of SAT instances.

Abstract
| Pages: 39-46
The primary causes of undernutrition in Bangladesh are its poverty, large population, socio-economic differences and inadequate access to health facilities. Adolescent are the most susceptible group for under nutrition and having great implication as they will be parent in future. Studies on the assessment of nutritional status of adolescents are less in number and have great implication for intervention. The present cross-sectional investigation evaluates the prevalence of undernutrition among rural adolescents (10 years - 17 years) from Chowhali subdistrict, Serajgonj, Bangladesh.The present investigation was conducted among 726 rural school-going adolescents (376 boys and 350 girls) belonging to the rural Muslim and Hindu communities. The nutritional status was assessed by anthropometry in terms of stunting (Height-for-age below 3rd percentile) and thinness (BMI-for-age below 5th percentile). The prevalence of stunting and thinness were high and estimated to be 46.6% and 42.4% respectively. The prevalence of stunting was estimated among boys (43.1%) and girls (50.3%) (p>0.05).Incase of boys of 17 years (63.6% )and girls of age 15years (70%) prevalence is the highest. The mean Body Mass Index (BMI)  of girls were more than the boys (16.8 ± 3.4 kg/m2 and 15.9 ± 2.1 kg/m2 respectively). The prevalence of thinness among boys (32.0) was more than the girls (32.0).The prevalence of thinness and stunting is high in the study area. Gender is a significant demographic factor of undernurition in the study area. Nutritional intervention  and communication is necessary to improve their nutritional status.

The empirical studies investigating a direct relationship between Strategy, Organizational structure, Financial aspect and Performance of Research and Development (R&D) have attracted criticisms, including the use of a bivariate methodology. While this relationship is critical to organizations using Strategy, Organizational structure, Financial aspect, the critics suggest that other factors will effect on the relationship between Strategy, Organizational structure, Financial aspect and Performance of Research and Development (R&D). In this article, the authors propose that dimensions of Government policy are important moderators on relationship between Strategy, Organizational structure, Financial aspect and Performance of Research and Development (R&D).

Copper sulphate, CuSO4.5H2O (Fine Chemical, India), Purity (99%) and CAS No. 7758-98-7, a broad-spectrum inorganic pesticide, has many-fold uses as fungicide, molluscicide and weedicide. The adult Indian skittering frog, Euphlyctis cyanophlyctis was treated In vivo with different sublethal concentrations of CuSO4 (3.5, 5.0, 6.5 and 8.0mg/kg) after calculating the LC50 value which was found to be 10mg/kg. Each dose was injected intraperitoneally once in the treatment period for 24, 48, 72 and 96hrs to study its potential toxic effect using micronucleus test. It was observed that copper sulphate induced a significant increase in frequency of micronuclei at different concentrations in frog for 24, 48, 72 and 96hrs when compared with the control. The results lead us to the conclusion that there is a dose-effect relationship in the induction in the frequencies of MN in different somatic tissues of the frog due to its genotoxic and cytotoxic properties.

Abstract
| Pages: 70-82
The purpose of the study was to evaluate the serum level of calcium (Ca) and iron (Fe) in type 2 diabetes mellitus (T2DM) with periodontitis subjects. A total of 450 subjects participated in the study, who were all distributed equally into three groups as control healthy individuals (group I), T2DM without periodontitis (group II), and T2DM with periodontitis (group III), matched for age, sex, and duration of diabetes. Serum concentrations of glucose, HbA1c, Ca, and Fe were measured using various methods. Student’s t-test, Pearson correlations, and analysis of variance (ANOVA) tests were used for statistical analysis. The serum Ca and Fe level was found to be significantly increased in T2DM with periodontitis (group III) and lowered in T2DM without periodontitis (group II) (P < 0.0001) when compared to control. Patients with T2DM with periodontitis has increased serum Ca level which are mainly released from the alveolar bone loss and increased Fe level further induces more complications in T2DM with periodontitis.

Abstract
| Pages: 83-98
The coastal marine ecosystem of Zanzibar is experiencing a decline of natural habitats and biodiversity. due to the changes in land use and land cover caused by increasing human. This study investigates the changes that have occurred between 2001 and 2011. Landsat ETM+ images were used to locate and quantify the changes. The intensity analysis method was employed to get quantitative information at interval and category levels only. The interval level examined how the size and speed of change vary across time intervals, and the category level examined how the size and intensity of gross losses and gross gains in each category vary across categories for each time interval. Results show that between 2001 and 2011, mangrove, cultivated land/shrubs and bareland covers declined by 127.4 ha, 46.0 ha and 10.2 ha respectively while mixed trees, “jangwa la bahari” and water increased by 147.2ha, 35.8ha and 0.6 ha respectively in Kisakasaka. Between the same time, cultivated land/shrubs, mangrove and mixed trees covers declined by 262.2 ha, 86.3 ha, 49.4 ha respectively while rice pads, barelends, “jangwa la bahari” and water has been increased by 165.6 ha, 109.7 ha, 103.9 ha and 18.7 ha respectively in Bumbwini.
