The AdS-CFT correspondence and the black-hole information theory paradox
(BRAC University, 2017)This thesis discusses the role of AdS/CFT correspondence in high-energy physics. It concentrates on studying the mathematical black holes in various backgrounds, particularly in the anti deSitter(AdS) space. In this ... -
Agrobacterium mediated transformation of two peanut (Arachis hypogaea L.) explants using Na⁺/H⁺ antiporter gene to generate transgenies to resist salinity stress
(BRAC University, 2018-07)Peanut is one of the most popular sources of healthy addible oil. Its susceptance to various biotic and abiotic stresses is limiting crop production worldwide. Salinity is prior to them. Moreover, it is strictly monocious ... -
Analysis of enteric pathogenicity of multidrug-resistant Pseudomonas spp. isolated from commercial UHT milk
(2018-09)Pseudomonas is a kind of bacteria that has the ability to develop resistance to antibiotics rather rapidly over several generations. This resistance present in some strains makes Pseudomonas a very difficult to treat once ... -
Analysis of factors influencing successful Agrobacterium-mediated genetic transformation in two Bangladeshi peanut (Arachis hypogaea L.) varieties BINA Chinabadam-2 and BINA Chinabadam-6 using embryonic leaflet explant
(BRAC University, 2014-03)Peanut (Arachis hypogaea L.) is an important crop both for its nutritional value and for its oil content in the seeds. But this economically important crop is susceptible to both biotic and abiotic factors that hamper its ... -
Analysis of factors influencing successful Agrobacterium-mediated genetic transformation in two different explants of peanut (Arachis hypogaea L.) variety BINA Chinabadam-2
(BRAC University, 2014-03)Peanut (Arachis hypogaea L.) is a nutritious oil-seed crop. It has low productivity due to its susceptibility towards many biotic and abiotic factors. It has incompatibility towards conventional breeding techniques, thus ... -
Analysis of multidrug resistant Klebsiella pneumoniae and Enterobacter aggalomerans isolates from under five children suffering from acute respiratory infections in Dhaka, Bangladesh.
(BRAC University, 2015-09)Emergence of resistance against multiple types or classes of antibiotics among bacterial pathogens associated with Acute Respiratory Infection (ARI) is a global concern. Since, ARI still remains the major cause of child ... -
Analysis of physicochemical parameters and microbial status in Gulshan lake water
(BRAC University, 2014-09-08)Microbiological evaluation and physicochemical parameters of lake comprises detection of indicator bacteria of water pollution and pathogenic bacteria present in the surface layers of water. Polluted water has a significant ... -
Analytical solution of non-linear partial differential equation by using the extended (𝐆′/𝐆) expansion method with non-linear auxiliary equation
(BRAC Univeristy, 2018-03-01)Among some new methods, these were introduced to find the exact solution of Non-Linear Partial Differential Equations (NLPDEs), (G'/G) expansion method proposed by Mingliang Wang, is straightforward and easy to handle ... -
Anisotropic charged stellar models in Generalized Tolman IV spacetime
(© 2015, Società Italiana di Fisica and Springer-Verlag Berlin Heidelberg, 2015)With the presence of electric charge and pressure anisotropy some anisotropic stellar models have been developed. An algorithm recently presented by Herrera et al. (Phys. Rev. D 77, 027502 (2008)) to generate static ... -
Antibacterial activity and medicinal properties of ginger (Zingiber officinale) in Bangladesh
