From vulnerability to resilience : A study of the livelihood struggles of tiger widows in Bangladesh
Nahid Sultana,Soma Dey 이화여자대학교 한국여성연구원 2021 Asian Journal of Women's Studies(AJWS) Vol.27 No.1
Livelihood management is a severe challenge in the coastal area near the Sundarbans mangrove forests of Bangladesh. Human-tiger conflict in the area further complicates the situation and generates a group of women known as tiger widows who have lost their husbands because of attacks by tigers. They are therefore socially stigmatized as cursed and harbingers of bad luck. As a result, the lives of these widows in rural and geographically remote locations are full of suffering and hardships, especially with respect to their being able to manage livelihoods. This article discusses their vulnerabilities and difficult lives in this antagonistic eco-social setting. It also reveals their adoption of different livelihood strategies backed by some NGOs’ development assistance, whereby they become able to secure the survival and well-being of their families. Furthermore, our findings show how the widows have developed capacities to transform their own lives from utter misery to gain socioeconomic stability by fighting patriarchal constraints and also influencing other women to become self-reliant.

A New Mathematical Model for Optimum Production of Neural Stem Cells in Large-scale
Hossain, S.M. Zakir,Sultana, Nahid,Babar, S.M. Enayetul,Haki, G.D. The Korean Society of Toxicogenomics and Toxicopro 2007 Molecular & cellular toxicology Vol.3 No.2
Millions of individuals worldwide are currently afflicted with neurodegenerative disorders such as Parkinson's disease and multiple sclerosis which are caused by the death of specific types of specialized cells in the Central Nervous System (CNS). Recently, Neural Stem Cells (NSCs) are able to replace these dead cells with new functional cells, thereby providing a cure for devastating neural diseases. The clinical use of neural stem cells (NSCs) for the treatment of neurological diseases requires overcoming the scarcity of the initial in vivo NSC population. Thus, we developed a novel 3-dimentional cellular automata model for optimum production of neural stem cells and their derivatives in large scale to treat neurodegenerative disorder patients.

The study was conducted to know the cyclic changes in gonadal maturation and to investigate the developmental stages of oocytes and testicular germ cells of an air-breathing fish, Channa striata. Fish were sampled monthly from lentic and lotic environments of three geographical locations of Bangladesh from December to November and the histological analysis of their gonad was done to evaluate the objectives. The highest mean GSI was 5.95 ± 0.20 for female in July and 0.14 ± 0.01 for male also in July showing that the gonadal development reached its peak during this month. The highest mean oocyte diameter was 1257.50 ± 24.17 μm observed in July implying that the oocyte reached maturity in this month. Histological study of ovary revealed the evidence of early yolk granule stage and late yolk granule stage from April to July. In case of male four stages of spermatogenesis were distinguished and spermatozoa were highly abundant in June and July. So the monthly pooled values of GSI and the analysis of gonadal histology indicated that the peak breeding season of C. striata occurred in July in the lentic and lotic environments. Samples collected from lentic and lotic habitats are suggestive of no difference in the development of the gonad. The results of the present study will be useful for selective breeding programme, conservation and sustainable fishery management of C. striata in its natural habitat.
