    Rahman, Md. Sajidur (University of Rajshahi, 2008)
    In the present work the functioning of a coupling of multi type data like remote sensing data, geophysical data, climatic data and other ancillary information, has been studied to address the driving forces related with ...
  • Mortality Trends, Differentials and Modeling for Mortality Forecasting in Bangladesh 
    Rouf, Abu Sayeed Md. Ripon (University of Rajshahi, 2017)
    Mortality is one of the most important vital events and it is a crucial indicator of socio-economic development in any nation. It is said that socio-economic development should be measured in terms of mortality. Bangladesh, ...
  • N-Ideals of a Lattice 
    Latif, Md. Abdul (University of Rajshahi, 1994)
    This thesis studies the nature of n-ideals of a lattice. The topic arose out of a study on the kernels, around a particular element n, of a skeletal congruence on a distributive lattice. The idea of n-ideals in a lattice ...
  • New Approximate Solution of Non-Linear Differential Systems 
    Pervin, Mst. Razia (University of Rajshahi, 2014)
    Most of the perturbation methods are developed to find periodic solutions of nonlinear systems; transients are not considered. At first, Krylov and Bogoliubov introduced a perturbation method which is well known as “asymptotic ...
  • A New Ledin from the Pulp of Punica granatum: Isolation, Charactemation and Antiproliferative Activities 
    Nurujjman, Md. (University of Rajshahi, 2017)
    A lectin (designated as PgL) was purified from the pulp of pomegranate (Punica granatum) by using Ion-exchange chromatography on DEAE cellulose column with the molecular mass of 28.0 ± 1.0 KDa as estimated by SOS-PAGE both ...
  • Nutritional, Phytochemical & Antidiabetic Properties of Oyster Mushroom (Pleurotus ostreatus) 
    Karim, Md. Rezaul (University of Rajshahi, 2013)
    Plants are often condemned as non-scientific and inactive. But various phytochemical and biological investigations have proved its therapeutic utility and functional properties. Now-a-days, the use of plant constituents ...
  • On Connectedness Concepts in Fuzzy Topological Spaces 
    Shayid, Md.Abu (University of Rajshahi, 2013)
    The goal of the thesis is to find out some new connectedness concepts in fuzzy topological spaces. Some concepts of connectedness in fuzzy topological spaces that already exist in the literature are recalled here also. In ...
  • On Finitely Generated n-ldeals of a Nearlattice 
    Rahman, Md. Mizanur (University of Rajshahi, 2006)
    The thesis studies extensively the nature of finitely generated n-ideals of a near lattice. Many authors including [1], [34] and [35] have studied about n-ideals of a lattice. A convex sublattice containing a fixed element ...
  • On Fuzzy Compactness 
    Talukder, Md. Abdul Mottalib (University of Rajshahi, 2015)
    The fundamental concept of a fuzzy set and fuzzy set operations was first introduced by L. A. Zadeh [175] in 1965 and it provides a natural foundation for treating mathematically the fuzzy phenomena, which exists pervasively ...
