Because trees cover only 6.4% of the total land area of Bangladesh, while agricultural expansion continues to massively deplete the natural forests, a well-managed homestead forestry practice is vital for reversing the existing trend and promoting the ecological balance of the country. An understanding of the decision-making process of the farmers who(More)
Let p ≥ 5 be a prime number and Fp−1(τ) be the solution of the above differential equation for k = p−1 which is modular on SL2(Z) (such a solution exists and is unique up to a scalar multiple). For any zero τ0 in H of the form Fp−1(τ), the value of the jfunction at τ0 is algebraic and its reduction modulo (an extension of) p is a supersingular j-invariant(More)
The parameter k always stands for a non-negative integer or half an integer throughout the paper. This differential equation originates in the work [1] where in some cases (k ≡ 0, 4 mod 6) solutions which are modular on SL2(Z) were found and studied in connection with liftings of supersingular j-invariants of elliptic curves. The purpose of this paper is to(More)
This paper includes a review of international sustainable forestry development followed by an analysis of forest policies in Bangladesh. There have been four different government forest policies in Bangladesh since 1894. The first two forest policies (1894 and 1955) were exploitative in nature. Most of the regulatory documents were developed during the(More)
Forests represent more than just a livelihood to many people in developing countries. In Bangladesh, for example, overwhelming poverty and socio-economic pressures have resulted in an unstable situation where intensive pressure on forest resources is having increasingly negative consequences for the population. Some studies have evaluated the benefits of(More)
Natural forests offer numerous benefits to indigenous communities and society at large. Incomes from forest sources play an important role in rural households. In addition to this, environmental sources in the forests contribute significantly to rural households’ livelihoods and economic well-being. This paper examines the contributions of forests to the(More)
Wide acceptance of sustainable development as a concept and as the goal of forest management has shifted forest management policies from a traditional to a people-oriented approach. Consequently, with its multiple new objectives, forest management has become more complex and an information gap exits between what is known and what is utilized, which hinders(More)
A study was conducted to investigate the land-use pattern change over a period of 18 years (1988–2006) by using remote sensing and Geographical Information System (GIS) technologies, in the West Bhanugach Reserved Forest, a hill forest, in Sylhet Forest Division of Bangladesh. The images were processed using ERDAS Imagine software. Both supervised and(More)
Light and electron microscopic findings in papillary endothelial hyperplasia of the mandible in a 49-year-old female are reported. The endothelial cell-lined papillary projection into a cystic lumen was examined by light microscopy and characteristic features of the endothelial cells were found by electron microscopy. Factor VIII-related antigen was(More)
Traditional systems of medicine have become a topic of global importance recently. Increased commercialization of economically important medicinal plants has resulted in overharvesting, threatening their survival. The present study was carried out to document the indigenous uses of medicinal plants by the local communities in and around Rema-Kalenga(More)
