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 and comparison between the Genome of CRISPR bacteriophages
(Brac University, 2019-12)Viruses that infect bacteria are called bacteriophages or shortened as phages. Like all viruses, Phages are absolute parasites, although carry all the information to direct their reproduction in an appropriate host, they ... -
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 ... -
