BRAC University is a private university in Dhaka, Bangladesh. The university was established by BRAC in 2001 under the Private University Act 1992. BRAC University had its first convocation in January 2006. Sir Fazle Hasan Abed, KCMG is the Chairperson of the Board of Trustees of BRAC University. Wikipedia.

Background: In Bangladesh, particularly in urban slums, married adolescent womens human rights to life, health, and reproductive and sexual health remain adversely affected because of the structural inequalities and political economic, social and cultural conditions which shape how rights are understood, negotiated and lived. Methods. The focus of the research and methods was anthropological. An initial survey of 153 married adolescent women was carried out and from this group, 50 in-depth interviews were conducted with selected participants and, from the in-depth interviews, a further eight case studies of women and their families were selected for in-depth repeated interviews and case histories. Results: This paper speaks of the unanticipated complexities when writing on reproductive rights for poor adolescent women living in the slums, where the discourses on universal human rights are often removed from the reality of adolescent womens everyday lives. Married adolescent women and their families remain extremely vulnerable in the unpredictable, crime-prone and insecure urban slum landscape because of their age, gender and poverty. Adolescent womens understanding of their rights such as the decision to marry early, have children, terminate pregnancies and engage in risky sexual behaviour, are different from the widely accepted discourse on rights globally, which assumes a particular kind of individual thinking and discourse on rights and a certain autonomy women have over their bodies and their lives. This does not necessarily exist in urban slum populations. Conclusions: The lived experiences and decisions made pertaining to sexual and reproductive health and rights exercised by married adolescent women, their families and slum communities, allow us to reflect on the disconnect between the international legal human rights frameworks as applied to sexual and reproductive health rights, and how these are played out on the ground. These notions are far more complex in environments where married adolescent women and their families live in conditions of poverty and socioeconomic deprivation. © 2011 Rashid; licensee BioMed Central Ltd.

This article reports the results of a qualitative study conducted in two villages of Matlab to explore the cultural dimensions of depression. Participants included adult men and women with and without a history of depressive episode (n=42), formal and informal healthcare providers (n=6), and caregivers (n=2). Adults (n=10) with a history of depressive episode were selected from a 2005 survey conducted by ICDDR,B. A case vignette was used for eliciting local terms for depression, perceived causes, impact, and treatments. Hardly anyone recognized the term bishonnota (literal translation of depression) used in the past survey. The participants thought that the vignette was about chinta rog (worry illness), and they spoke of somatic symptoms in relation to this condition. When explored further, they mentioned sadness and psychological complaints. Men felt that it affected them more while women felt the opposite. They associated chinta rog with poverty and social issues with impacts on marriage, work, and education. From their responses, it seemed that they preferred a psychosocial framework attributing the cause to thoughts and emotions, resulting from social causes. Commonly-suggested treatments were more income, better relationships, and tablets. Former health providers were often the first choice for help-seeking. The study hopes to 'culturally inform' the formal healthcare providers and programme planners. © International Centre for Diarrhoeal Disease Research, Bangladesh. Source

Improvement of cell coverage and network capacity are two major challenges for the evolving 4G cellular wireless communication networks such as LTE-Advanced networks. In this context, hierarchical layering of cells with macro base stations coexisting with low-power and shortrange base stations (corresponding to picocells or femtocells) in a service area is considered to be an efficient solution to enhance the spectralefficiency of the network per unit area. Also, such a hierarchical cell deployment, which is referred to as a heterogeneous network, or Het-Net, provides significant improvement in the coverage of indoor and cell edge users and ensures better QoS to the users. Interference mitigation between different layers is one of the key issues that needs to be resolved for successful deployment of HetNets. To this end, fast frequency response, FFR, is considered to be an efficient intercell interference coordination technique for OFDMA-based HetNets. This article focuses on evaluating three state-of-the-art FFR deployment schemes: strict FFR, soft FFR, and FFR-3 schemes for OFDMA-based two-tier HetNets comprising macrocells overlaid with femtocells. Also, a variation of the FFR-3 scheme, which is referred to as the optimal static FFR (OSFFR) scheme, is proposed. A broad comparison among all these FFR schemes is performed by using Monte Carlo simulations considering performance metrics such as outage probability, average network sum rate, and spectral efficiency. Simulation results show that, the average gains in spectral efficiency (b/s/Hz) of the network are significantly higher for the proposed scheme when compared to the strict FFR, soft FFR, and FFR-3 schemes. © 2002-2012 IEEE.

In this article, new (G′G)-expansion method and new generalized (G′G)-expansion method is proposed to generate more general and abundant new exact traveling wave solutions of nonlinear evolution equations. The novelty and advantages of these methods is exemplified by its implementation to the KdV equation. The results emphasize the power of proposed methods in providing distinct solutions of different physical structures in nonlinear science. Moreover, these methods could be more effectively used to deal with higher dimensional and higher order nonlinear evolution equations which frequently arise in many scientific real time application fields. © 2013 Copyright 2013 Author(s).

Structural and magnetic properties of Cu substituted Ni 0.50-xCuxZn0.50Fe2O4 ferrites (where x=0.00.25) prepared by an auto combustion method have been investigated. The X-ray diffraction patterns of these compositions confirmed the formation of the single phase spinel structure. The lattice parameter increases with the increase in Cu2 content obeying Vegards law. The particle size of the starting powder compositions varied from 22 to 72 nm. The theoretical density increases with increase in copper content whereas the Néel temperature decreases. The bulk density, grain size and permeability increases up to a certain level of Cu2 substitution, beyond that all these properties decrease with increase in Cu2 content. The bulk density increases with increase in sintering temperatures up to 1250 °C for the parent composition, while for substituted compositions it increases up to 1200 °C. Due to substitution of Cu2, the real part of the initial permeability increases from 97 to ∼390 for the sample sintered at 1100 °C and from 450 to 920 for the sample sintered at 1300 °C. The ferrites with higher initial permeability have a relatively lower resonance frequency, which obey Snoeks law. The initial permeability strongly depends on average grain size and intragranular porosity. The saturation magnetization, M s, and the number of Bohr magneton, n(μB), decreases up to x=0.15 due to the reduction of the AB interaction in the AB 2O4 spinel type ferrites. Beyond that value of x, the Ms and the n(μB) values are enhanced. The substitution of Cu2 influences the magnetic parameters due to modification of the cation distribution. © 2011 Elsevier B.V.
