Dielectric Permittivity Measurements of Electronics Cooling Fluids
(2013-09-23)
High performance electronics often present heat management challenges which can, in some applications, be mitigated through the use of liquid cooling technologies. In this work, select 3M Novec and 3M Fluorinert dielectric ...
Diet-induced Gut Microbiome and Colon Transcriptome Changes in C57BL/6J, C57BL/6N and HCA2-/- Mice
(2020-11-24)
Genetic variation drives phenotypic and gut microbiome diversity, while also regulating metabolism and immune responses. C57BL/6J and C57BL/6NCrl inbred mice strains have different metabolic phenotypes in response to ...
Dietary Intake Variables as Predictors of Weight Status and the Prevalence of At-Risk for Overweight and Overweight African American Preadolescents: An 18 Month Study
(2012-05-23)
This exploratory quantitative, repeated measures research design investigated whether the dietary intake variables of preadolescents’ and their caregivers could be used to predict the weight status of African American ...
Dietary mercury and stress responses: how lifetime exposure to mercury alters stress responses and their relationship to spatial cognition
(2019-04-25)
Methylmercury is a widespread environmental contaminant that negatively impacts both humans and wildlife at sublethal levels. While environmental sources of methylmercury exist, the primary sources are anthropogenic, and ...
Dieting, Alcohol Use, and Impulsivity in a Sample of Undergraduate Students
(2011-07-01)
Dieting behavior is correlated with frequency and quantity of alcohol use and alcohol related problems. Research has also shown that dieting behaviors are correlated with impulsivity, as measured by self-report questionnaires. ...
