A study to investigate the correlation of abundance between the spacers and the prophages in bacterial genome
(Brac University, 2019-09)Bacteriophages, the most abundant and diverse entities in the biosphere which are composed of a nucleic acid molecule that is surrounded by a protein structure. These viruses can infect or kill bacteria through lytic and ... -
Studying vibrio spp. in industrially polluted surface waters : difficulties and uncertainities during characterization
(BRAC University, 2018-11)4 Abstract . Being the capital of Bangladesh Dhaka city faces multiple pollution problems due to rapid urbanization leading to unplanned industrialization. This often results in the contamination of water bodies with ... -
Sundarban is a potential source for anticancer and antioxidant plant
(Brac University, 2021-07)Different factors, for example, physical, compound, ecological, metabolic and hereditary variables that play a direct as well as aberrant part in the acceptance and disintegration of various kinds of cancer. It was ... -
Supersymmetric gauge theory: an application of group theory in high energy physics and starobinsky model of cosmological ination
(BRAC University, 2016)This thesis discusses the general role of symmetry in high-energy physics. It concentrates on the role of fermionic symmetry generators, which generate the symmetry known as supersymmetry. An extensive discussion of ... -
Surveillance of low pathogenic avian influenza in Dhaka District
(BRAC University, 2014-08)This present research was under taken with a view to investigate the epidemiological and molecular study of Low pathogenic Avian Influenza (LPAI). For this purpose samples were collected from 800 clinically healthy birds ... -
Survey and analysis on oral microbial profile of Dhaka city dwellers and their association with different diseases in the community
(Brac University, 2023-09)This research aims to determine the composition of the human oral microbiota, comprising various microorganisms inhabiting the oral cavity exist in the human mouth. The oral microbiota plays a vital role in human health, ... -
Survey on patients undergoing treatments for cervical, endometrial and ovarian cancer
(Brac University, 2019-01)Cancer is a disease with an abnormal cell growth and it can invade or spread from one organ to another. There are some common symptoms noticed for cancer like abnormal bleeding, lumps, weight loss and change in bowel ... -
Synergistic effect of iron-oxide NPs conjugated with antibiotics against gram-positive and gram-negative bacteria
(Brac University, 2023-06)Antimicrobial resistance (AMR) has become a worldwide public health issue. Pathogenic bacteria are gradually developing novel antibiotic resistance mechanisms. Enhanced treatment strategies, such as alternative drugs or ... -
Synthesis and antibacterial activities of silver nanoparticle
(BRAC University, 2019-01)Antibiotic resistance is on the rise for the last few decades. As commercial antibiotics are failing to combat microbes, alternative methods are being investigated. The properties of silver as disinfectant have been known ... -
System of linear equations in Computed Tomography (CT)
(BRAC University, 2018-09)In X-rays the internal structures often overlap, thereby it reduces the chances of detecting any anomalies (if any) and hence the patient may be given an improper diagnosis or they will have to suffer due to participating ... -
Target specificity of different phytochemicals in preventing the binding of OxLDL To LOX-1: An in silico approach
(Brac University, 2022-06)With an estimated 17.9 million deaths each year, cardiovascular disease (CVD), particularly myocardial infarction (MI), is the leading cause of death globally. Most MIs are caused by thrombi that form over ruptured ... -
Targeted bacteriophage application to control water contamination by Escherichia coli, Vibrio and Salmonella
(Brac University, 2022-04)Water contamination and scarcity of pure water is a major issue of concern in our country. Water borne epidemics caused by different strains of Escherichia coli, Salmonella or Vibrio have become more frequent in many ... -

Transgenic tomato (Solanum lycopersicum Mill.) regeneration by comparing different transformation techniques
(BRAC University, 2015-08)Production of saline-tolerant high-yielding crop has become most important in the current global scenario. Biotechnological approaches are extensively employed for introducing foreign genes into high-yielding genotypes. ... -
Travelling wave and non-travelling wave solutions of nonlinear evolution equation via new generalized and Improved (G'/G) - expansion method
(BRAC Univeristy, 2018-03-01)In this thesis, we have applied the new extension of the generalized and improved ( G' / G) - expansion method in order to find the explicit solutions of non-travelling and travelling wave solutions of Fisher equation. ... -
Trends of multidrug resistance phenotypes in vibrio cholerae causing cholera in Bangladesh
(Brac University, 2023-06)Antibiotic resistance is a growing global concern, posing significant challenges in the treatment of bacterial infections. Vibrio cholerae, a gram-negative bacterium responsible for the severe diarrheal disease cholera, ... -
Tsunami source uncertainty estimation: the 2011 Japan tsunami
(© 2016 Blackwell Publishing Ltd, 2016)This paper studies the initial sea surface displacement and its uncertainty after an earthquake based on tsunami waveforms. The spatial distribution is inferred with a Bayesian approach that provides probabilities that are ... -
A two loop test of Matrix Big Bang Model
(Brac University, 2020-06)In this thesis we expand the effective action for the Matrix Big Bang presented in [9, 10] and indicate the interaction terms. Then we compute the two loop effective potential of this Matrix Big Bang model. We show that ... -
Understanding the effect of exposure of human pathogens to polluted surface water: Salmonella as a model organism
