Effects Of Bisphenol A And Nicotine On Cytochrome P450s In Brain And Liver Of Pregnant Rats, Mohammad Merii, Manal Fardon, Mahmoud Khalil

BAU Journal - Science and Technology

Bisphenol A (BPA), a widely used chemical, is associated with endocrine disruption through its interactions with the aryl hydrocarbon receptor (AhR). BPA crosses into the human body mostly through migration from plastic packaging into the daily diet. AhR regulates the expression of drug-metabolizing enzymes (DMEs), including numerous CYP450s, and mediates xenobiotic reactions. This study aims at examining how the expression of CYP450s expression is affected, in the brain and liver of pregnant rats, by exposure to BPA and nicotine. Pregnant female Sprague-Dawley dams were exposed to increasing doses of BPA; 0 (control), 50, 500, and 5000 g/kg/day , or in …

Reviving Knowledges Through Play And Resistance: The Case Of Navajo Conceptions Of Space, Daniel Ness, Richard D. Sawyer

Northwest Journal of Teacher Education

The authors explore a possible cause of epistemicidal predispositions of the dominant Eurocentric curricula. They posit that one way to determine a plausible contributing factor of this increasing devastation is to consider epistemicide through the lens of intellectual development. To do this, the authors examine parallel patterns of behavior in the domains of developmental and cognitive psychology. The authors then discuss an alternative framework to the Western conception of space within formal K-12 education by presenting the Navajo conception of space and play. Throughout the paper, the authors argue that all students—and especially those living in poverty in commercially constructed, …

A Simplified Model For The Intermediate Structure Of Strong Fire Whirls, Forman A. Williams

Progress in Scale Modeling, an International Journal

A model is described for the overall structure of intense fire whirls, based on a spatially evolving vortex, with circulation enhancement driven by the axial acceleration of low-density gas in the core through the axial pressure gradient. The axial acceleration increases the entrainment rate into the core which, through mass conservation, increases the circulation if the angle between the tangential and radial velocity components remains fixed. The two-zone model employs general balance equations for regions inside and outside a cylinder of fixed radius, each inviscid, the inside region being presumed to have a constant density small compared with the (constant) …
