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 ... -
Evaluation of the antioxidant and in vivo anticancer activity of Excoecaria agallocha bark extract
(Brac University, 2019-10)Mangrove ecosystems have been known to possess diverse secondary metabolites and a good number of bioactive compounds of pharmaceutical importance have been reported from the mangrove plants. Mangrove plants are biochemically ... -
Horizontal transfer of antibiotic resistance between trans-gram bacteria in surface water of Dhaka city
(Brac University, 2019-10)A global medical crisis has already started as antibiotics have started losing their effectiveness against the growing number of bacterial pathogens. Horizontal Gene Transfer (HGT) system has a great impact on this spreading ... -
Incidence, molecular characterization and antibiotic resistance profile of Methicillin resistant staphylococcus aureus Isolated from clinical origin and associated surroundings in hospital
(Brac University, 2019-10)Methicillin-Resistant Staphylococcus aureus (MRSA) is notorious for its resistance to Penicillin derivative antibiotics and is also resistant to multiple drugs. In Bangladesh, the prevalence of MRSA is a staggering 72%. ... -
Characterization of Hepatitis B surface Antigen gene containing recombinant Pichia pastoris
(Brac University, 2019-10)Hepatitis B is a potentially life-threatening liver infection caused by the Hepatitis B virus. It is a major health problem worldwide. So, the development of safe and effective vaccines against this disease can be a huge ... -
Virulence determinants and antibiotic resistance of Extended-Spectrum Beta-lactamase (ESBL) producing Klebsiella pneumoniae Isolated from hospital environment
(Brac University, 2019)Klebsiella pneumonia is a member of gram-negative Enterobacteriaceae associated with community and hospital-acquired infections through highly resistant clones. Infection by Carbapenem-resistant Klebsiella is increasing ... -
Comparison of mutation spectrum, hemoglobin profiles and hematological features between transfusion dependent and non-dependent patients of Hb E/β Thalassemia
(Brac University, 2019)Hemoglobin E/β Thalassemia is an inherited anemic genetic disorder that is highly prevalent in the Southern Asia part of the world. Bangladesh falls in the Thalassemia belt of the world. The clinical manifestation of this ... -
Prevalence of Zika virus infection in patients with Guillain-Barre syndrome in Bangladesh
(Brac University, 2019-10)Guillain–Barre syndrome (GBS) is an autoimmune disease where the immune system of the body attacks the peripheral nervous system causing demyelination of the axon. This is the leading cause of acute flaccid paralysis (AFP) ... -
Isolation and molecular characterization of e.coli bacteriophages from surface water of Bangladesh
(Brac University, 2019-12)In our country Diarrheal epidemics occur seasonally. Two peaks of outbreaks agreeably coincide with dry season and monsoon rain. Several factors control the outbreaks to occur and collapse. Bacteriophages are one of them ... -
Mutation patterns in the HBB gene determine the frequency and onset of blood transfusion in patients with beta-thalassemia major and HbE-beta thalassemia
(Brac University, 2019-11)Thalassemia is a blood disorder passed down through families (inherited) in which the body makes an abnormal form or inadequate amount of hemoglobin. Co-inheritance of beta-thalassemia alleles from two parents results ...
