The project presents the comprehensive explanation to thermoelectronics and is intended to provide the details overview of all the techniques that are used throughout this research as well as the change in behaviors of the samples due to their doping levels and nanowire lengths. As examples of practical realization of the measurement principles, the setup is for Seebeck coefficient measurements which are the result of the slope of voltage gradient over temperature gradient. The comparisons among the measurements of each setup are done in order to understand and observe the electrical contacts and transport behaviors of the samples. Throughout the investigation, an interesting result has been found that is, the control sample without any grown nanowire gives very different results from the rest of them for almost all the measurements and the current - voltage curves seem to be more ohmic with the grown nanowires samples. © 2013 IEEE.

Fast food industry is a high growing sector of Bangladesh. It is concerned with the tastes and habits of the people. The food-taking habit especially in fast food segment has been changing very fast over last decade among the people of Dhaka - the capital city of Bangladesh. The reasons could be attributed by the increase of awareness, growth of education, development of information technology, and expansion of television channels and print media in Bangladesh. Hence, this paper aims at identifying the preference factors of fast food consumers living in Dhaka city. This study was conducted among the university students who usually eat fast food at their leisure time. To conduct the study, a total of 250 respondents were interviewed with a structured questionnaire. Both descriptive and inferential statistics were used in analyzing the data. Multivariate analysis technique like factor analysis was performed to identify the preference factors of the fast food student-consumers of Bangladesh. Multiple regressions were run to identify the relationship between the factors identified and the overall preference of the consumers. Results show that the consumers give most importance on brand reputation of the food item followed by nearness to receive and accessibility, similarity of taste with previous experience, cost and quality of the food, discount and taste, cleanliness and hygiene, salesmanship and decoration, fat and cholesterol level, and self-service factors. This study suggests that the brand reputation, nearness and accessibility, similarity in taste, and cost and quality relationship should be emphasized to improve the attraction of the university students towards the fast food items in Bangladesh.

The Mughal settlements are an integral part of Old Dhaka. Uncontrolled urbanization, changes in land use patterns, the growing density of new settlements, and modern transportation have brought about rapid transformation to the historic fabric of the Mughal settlements. As a result, Mughal structures are gradually turning into isolated elements in the transforming fabric. This study aims to promote the historic quality of the old city through clear and sustainable integration of the Mughal settlements in the existing fabric. This study attempts to analyze the Mughal settlements in old Dhaka and correspondingly outline strategic approaches to protect Mughal artifacts from decay and ensure proper access and visual exposure in the present urban tissue. © 2013 Higher Education Press Limited Company.

In vitro Dissolution behaviour of a poorly water-soluble drug, atorvastatin calcium (ATC) from its solid dispersion (SD) systems with poloxamer 407 (P407) has been investigated to develop a novel formulation with enhanced dissolution rate. Solid dispersion of drug-carrier ratios (1:0.5, 1:1, 1:1.5 and 1:2) prepared by solvent evaporation method, were premeditated for drug loading, saturation solubility and dissolution behavior. Saturation solubility study and dissolution test were carried out in both phosphate buffer (pH 7.4) media and distilled water. Solid dispersions were found effective to enhance the solubility of ATC significantly in all the media. In the dissolution study, SD at the ratio of 1:1 (drug: carrier) was found to be most effective, showed fastest and higher drug release. The higher ratios of poloxamer 407 (1:1.5 and 1:2) in SD were found to sustain the release rate of drug which might be owing to its gelling tendency in higher proportion at elevated temperature. Fourier Transform Infrared Spectroscopy (FT-IR) of solid dispersions with pure drug revealed no drug-carrier interactions. Thermogram and short term stability studies ensured that the prepared SDs were stable. So, solid dispersion may be an effective technique to prepare immediate and sustain release atorvastatin calcium. Source

The problem of steady conjugate heat transfer through an electrically-conducting fluid for a vertical flat plate in the presence of transverse uniform magnetic field taking into account the effects of viscous dissipation, Joule heating, and heat generation is formulated. The general governing equations which include such effects are made dimensionless by means of an apposite transformation. The ultimate resulting equations obtained by introducing the stream function with the similarity variable are solved numerically using the implicit finite difference method for the boundary conditions based on conjugate heat transfer process. A representative set of numerical results for the velocity and temperature profiles, the skin friction coefficients as well as the rate of heat transfer coefficient and the surface temperature distribution are presented graphically and discussed. A comprehensive parametric study is carried out to show the effects of the magnetic parameter, viscous dissipation parameter, Joule heating parameter, conjugate conduction parameter, heat generation parameter and the Prandtl number on the obtained solutions. © 2010 Elsevier Ltd.
