Ethanol production from kitchen waste by wild type yeast isolated from natural sources
(Brac University, 2020-02)It is time we think about changing to alternate fuel and make energy production procedures greener. Bioethanol production by microbes is one step towards it. In this study, yeast from easily available food sources was ... -
Isolation, screening and production of cellulase from Bacteria
(Brac University, 2019-12)Cellulase finds uses as raw material in various industries. The current sources of cellulase are highly expensive. However, using bacteria as cellulase producers can bring the cost down and make our industries ... -
Safety Assessment of Citrobacter freundii Bacteriophages for Use in Phage Therapy in the Face of Antibiotic Resistance
(Brac University, 2020-02)Citrobacter freundii is a species of bacteria in the Enterobacteriaceae family that is known to cause hospital-acquired infections in the respiratory tract, urinary tract, blood, and other normally sterile sites in ... -
Molecular assessment of bacteriophage genome as a potential therapeutic agent in treating multi-drug resistant bacterial infection
(Brac University, 2019-12)Bacteriophage therapy sheds a fresh light upon the critical growth of antibiotic resistance. Antimicrobial resistance, one of the major public health concerns, requires a novel therapeutic strategy to be optimized. Phage ... -
Detection of antibiotic resistance spectrum and resistance genes for aminoglycoside, macrolide, and β-lactam antibiotics using wound swab samples
(Brac University, 2020-01)Antibiotic resistance has become a global health problem with a decrease in efficacy in treating common infections, resulting in increased sufferings, duration of hospital stay and economic burden. Infections in the wound ... -
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 ... -
Effect of D122N mutation in BAK1 on structural integrity of protein complex consisting FLS2, flg22 and BAK1 ectodomain- a molecular dynamics study”
(Brac University, 2020-01)Elongated (elg) phenotype of Arabidopsis thaliana is caused by D122N mutation in the third leucine repeat of BRI1-associated kinase 1 (BAK1) protein that changes the 122nd amino acid aspartate to asparagine. The mutation ... -
Isolation and characterization of Bacteriophages from surface water specific for Vibrio Cholerae
(Brac University, 2020-01)The severe diarrheal disease cholera is caused by the bacterium Vibrio cholera. Toxigenic Vibrio cholerae strains belonging to O1 and O139 serogroups are the causative agents of epidemic and pandemic cholera. The Vibrio ... -
Review and application of the BenderWu Mathematica Package
(Brac University, 2018-12)This thesis is the application of the BenderWu Mathematica package to di erent physical systems. The code was developed to calculate wave function and energy data of higher order perturbation theory in quantum mechanics. The ... -
Pathway analysis of Disease-Gene associated network in the human breast cancer
(Brac University, 2020-01)The research of human genes and diseases is very interrelated and can lead to an improvement in healthcare, disease diagnostics, and drug discovery. In this work, a system was established to construct similarity measures ... -
Assessing the amount of total Coliform and the amount of Heavy Metals, Chromium and Lead from household water from different industrial zones of Dhaka Division (Tejgaon and Tongi)
(Brac University, 2019-12)The immensity of the global safe water crisis is underrated, though for decades’ water has been contemplated as the most imperative natural finite resources that is required for human development and existence. The ... -
An investigation of Mobilized Colistin-Resistance (MCR) gene and underlying dissemination mechanism using clinical, poultry and environmental samples in Bangladesh
(Brac University, 2020-01)Colistin, widely considered as the last-resort antibiotic for the treatment against multidrug-resistant (MDR) gram-negative bacteria worldwide, is being used indiscriminately in the poultry, livestock and fishery farms ... -
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 ... -
Assessing the amount of Pseudomonas aeruginosa and the amount of Heavy metals, Lead (Pb) and Chromium (Cr) from household water from different industrial zones of Dhaka Division (Hazaribagh and Savar)
(Brac University, 2019-12)Water is the major natural reservoir of the atmosphere - not so much in volume as in time and contact. Water is the indispensable environment resource for human security, the driven force of engines of sustainable ... -
Non-local gravitational interactions and the black hole information paradox
(Brac University, 2019-12)This thesis looks into Non-local gravitational interactions that hawking radiated quanta’s from Black holes might possess. We shall first explain Hawking’s original calculation in [1], and how such a process would lead to ... -
Quantisation of Black hole horizon area and multipartite entanglement of Black hole information subsystems
(Brac University, 2019-12)We formulate a model consisting of multipartite entanglement that helps provide a physical significance to the Bekenstein-Hawking entropy obtained after quantising the horizon area of a black hole as proposed by Jacob ... -
Combined effect of Cefixime and Azithromycin against multiple antibiotics resistant Klebsiella pneumoniae and Pseudomonas aeruginosa
(Brac University, 2019-12)Pneumonia is a lung infection with a variety of possible causes. It can be a severe disease with an infection of bacteria, virus or fungus. The lungs are inflamed and the tiny air sacs become filled with fluid inside. ... -
Prevalence & antibiotic susceptibility patterns Of pathogens obtained from the lower respiratory tract Of patients from NIDCH Dhaka-Bangladesh
(Brac University, 2019-12)Lower Respiratory Tract Infections (LRTIs) are very common and the usual way to treat them is by using antibiotics. Recently, treatment has become more complicated since most of the pathogens that cause these infections ... -
Perturbations on time dependent Orbifold Singularities
(Brac University, 2019-12)We start with the standard time-dependent backgrounds such as the geometry and dynamics of Freidmann-Robertson-Walker(FRW) cosmologies. First, we discuss the dynamics and geometry of FRW cosmologies. Then we introduce ... -
