Investigation Of Intergroup Bias In Two Neuromaturationally Distinct Age Cohorts: An Erp Study, Reuven M. Hanna
Investigation Of Intergroup Bias In Two Neuromaturationally Distinct Age Cohorts: An Erp Study, Reuven M. Hanna
Electronic Theses and Dissertations
Currently, sociological investigation of adolescent behavior focuses on the intersection of biography, history, and structure to explain adolescent risk-taking, reward-seeking, impulsivity, novelty-seeking and peer-salience. However, the preponderance of the evidence points away from social ecology and to a significant neuromaturational restructuring event between the 12th and 25th years of life as the root of adolescent behavioral tendencies. As a result, sociological social psychology can benefit from engaging in basic research using neuroscience methods. The present study expands the dual systems model of brain development to account for maturational changes in the social brain network as a way to explain social …
Hydrodynamic Cavitation As In-Line Process To Control Common Dairy Sporeformers, Pratibha Chaudhary
Hydrodynamic Cavitation As In-Line Process To Control Common Dairy Sporeformers, Pratibha Chaudhary
Electronic Theses and Dissertations
Sporeforming bacteria and their endospores have the ability to survive thermal treatments and proliferate in the milk and dairy products to cause spoilages. We applied the effect of hydrodynamic cavitation in controlling these bacteria and their spores at pilot scale level. Our aim was to investigate a technology that would improve the microbial quality of milk and dairy products, and is capable of being scaled up to be adapted at industrial level. Cavitation damages the cell walls of the bacteria and their endospores (releasing dipicolinic acid, responsible for endospore resistance to extreme conditions), thereby making them susceptible to thermal treatments …

Design, Synthesis, And Evaluation Of Gunw-3 As A Brain Targeting Agent, Asim Najmi
Electronic Theses and Dissertations
The blood brain barrier (BBB) is a barrier in the brain that separates the peripheral blood circulation system from the central nerve system (CNS). The barrier effectively protects the brain from xenobiotics. The BBB serves as a physical barrier through the tight junction of endothelial cells that were found to be 50-100 times tighter than that of normal endothelial cells. Different drug efflux pumps such as P-glycoproteins and multidrug-resistance proteins are found to be overdistributed on the BBB. These drug efflux pumps help pump xenobiotics out if they enter the cells and serv as an additional mechanism to prevent xenobiotics …
