The river Sitalakhya, one of the most important and prominent rivers in the flood plain region of Bangladesh is located in Narayanganj, an industrial zone of the country. The present deterioration of its water quality is not related to the water itself but also to the danger of diffusion of toxic substances into the ecosystem....

In the first chapter some basic notions and results from commutative algebra are being introduced along with a description on the progress towards the Stanley\'\'s conjecture. In the second chapter, we have discussed the Stanley\'\'s conjecture for a polynomial ring over a field in four variables....

The aim of this book is to explore the algebraic and combinatorial properties of simplicial complexes. Let S = k[x1, x2, ..., xn] be a polynomial ring over an infinite field k. Note that, there is a natural bijection between the square-free monomial ideals (so called non facet ideals) and simplicial complexes introduced by R.P. Stanley....

Mulberry, Morus alba L., as a non-toxic natural therapeutic agent, belongs to the family of Moraceae, and has been cultivated in many Asian countries such as China, India, Korea, Japan and Thailand where the leaves were used as food for silkworms....
