Determinants of Perception and Impact of Climate Change Induced Events on Livelihood of People in the Haor Area of Kishoreganj, Bangladesh
(IOS Press, 2021-11-19)Abstract: Bangladesh is prone to the danger of different natural calamities and is going to be most affected due to climate change-induced events in the upcoming decades. This study attempted to assess the farmers’ ... -
Development of appropriate structured mathematical models for fish population dynamics along with efficient numerical schemes for the solutions of the developed and other models of engineering problems
(Shahjalal University of Science and Technology(SUST), 2017-11)This thesis is mainly concentrated to obtain numerical solutions of real world problems encountered in continuum mechanics and other branches of sciences like development, management and production oriented ... -
INVESTIGATION OF NONLINEAR OPTICAL RESPONSES OF BOVINE SERUM ALBUMIN AND SOME AMINO ACIDS USING Z-SCAN TECHNIQUE
(Shahjalal University of Science and Technology(SUST), 2023-07)The Z-scan technique is a relatively simple but sensitive technique for studying third-order Nonlinear optical effects in materials. In this research work, we have implemented the continuous wave (CW) ... -
Multiple Beam Interferometry for Third Order Optical Nonlinearity
(2017-08)An experimental research work has been done to estimate the nonlinear refractive index of 2, 5 - dimethylaniline (DMA) by multiple (three) beam interferometry using a Mach-Zehnder interferometer. 2, 5 - dimethylaniline was ... -
RURAL-URBAN MIGRATION IN BANGLADESH: PATTERN AND IMPACT
(SUST, 2014-07)It is well-documented that migration in general and rural-urban migration in particular contributes a lot to the socioeconomic transformation of both global and national economies. Keeping this ... -
Spin Lattice order in frustrated Nickel- Zinc-Chromite (Ni x Zn 1-x Cr 2 O 4 ) System
(Shahjalal University of Science and Technology(SUST), 2016-04)ZnCr 2 O 4 compound is well known to show the frustration of the spin structure. At 12 K, ZnCr 2 O 4 distorts to break symmetry of the degenerated frustrated spin states by the spin- Peierls-like phase transition, ... -
A study of quality of different kinds of bricks and other building materials available in Bangladesh using neutron radiography technique and design of a small scale neutron radiography facility
(Shahjalal University of Science and Technology(SUST), 2015-10)Manufacturing building materials has become very good option of business in the developing countries like Bangladesh. Quality control of these materials and environmental friendly structure assurance ... -
A Study of Recognition and Enumeration for Decomposable Ordered Sets
(Shahjalal University of Science and Technology, 2021-11)In this research, we consider mainly two repeatedly studied combinatorial problems in the theory of posets (partially ordered sets). The first one, known as the Recognition Problem, is to recognize those classes of posets ... -
A Study on P-algebras and Its Underlying Lattices
(Shahjalal University of Science and Technology(SUST), 2016-03)In this thesis we study p-algebras and its underlying lattices. An algebra L = ⟨L, ∧, ∨, ∗ , 0, 1⟩ is called a p-algebra if (i) ⟨L, ∧, ∨, 0, 1⟩ is a bounded lattice, and (ii) for all x, y ∈ L, x ∧ x ∗ = 0 and x ∧ y ... -
Third Order Optical Nonlinearity with Far Field Diffraction Rings
(SUST, 2017-08)An experimental work has been done to study the third order optical nonlinearity of 2,5- dimethylaniline (DMA). The nonlinear phase shift and the nonlinear refractive index of DMA were estimated using the Far Field ... -
TREATMENT OF WATER-SOLUBLE DYES USING DIFFERENT PHYSICOCHEMICAL METHODS
(Shahjalal University of Science and Technology(SUST), 2023-06)Water quality is crucial for human welfare, yet industrial activities continue to contaminate freshwater sources with toxic dyes, adversely affecting soil, crops, aquatic life, and human health.This thesis investigates the ... -
Trends and Pattern of Population Aging: Potential Socio- Demographic Consequences in Bangladesh
(Shahjalal University of Science and Technology(SUST), 2021-06)The rapid aging of the global population presents unprecedented challenges, particularly in developing countries like Bangladesh, which is experiencing significant demographic transition.This research paper examines the ... -
Wigner Rotation in Flat Space, Hyperbolic Space and the Outer Space of a Schwarzschild Black Hole
(Shahjalal University of Science and Technology(SUST), 2020-02)We have represented Lorentz transformation and its consequences, i.e. time dilation and length contraction. The velocity addition formula has also explained. The formula of the transformation of orbital angular ...
