Many studies addressing the toxicity of silver nanomaterials have found that smaller sized silver nanoparticles are usually more toxic to organisms and in cell culture than particles of larger sizes yet it is not entirely clear why. We investigated the size dependent toxicity of silver nanoparticles by measuring the response...
The microsporidian parasite, Pseudoloma neurophilia, is the most commonly diagnosed infectious disease in laboratory populations of the zebrafish, Danio rerio. Infections by P. neurophilia are generally subclinical, however, they can become acute either incidentally or due to experimental immune suppression. Non-protocol induced variation can confound results in laboratory experiments using...
A gas-permeable-membrane-supported (GPMS) biofilm consisting
of methylotrophic bacteria was effective in degrading chlorinated
methanes, ethanes, and ethenes. The biofilm was developed on a
gas-permeable fabric (Goretex, W.L.Gore & Associates, Elkton,
Maryland) that divided a reactor vessel into a liquid compartment
and a gas compartment. Goretex is a nylon-backed teflon mesh...
Polycyclic aromatic hydrocarbons (PAHs) and oxygen-substituted PAHs (OPAHs) are environmental contaminants present in urban air, dust, soil and water resulting from incomplete combustion of organic materials or fossil fuels; found in crude oil and coal; and formed through photoxidation or biotransformation of microbial. It is widely recognized that PAHs pose...
In 2010, Mexican cuisine was declared as intangible cultural heritage, integral to Mexican identity and necessary to preserve for the good of humanity. Despite this recognition, first-generation Mexican communities in the United States face an exacerbated likelihood of experiencing food insecurity. In most United States studies, understanding the relationship between...
We designed an experiment to see if turbulence induced by shear instability
could be a mechanism. Using equipment readily available we completed
an experiment from the Ice Island T-3. A sensor array of current meters
and thermistors (described later on) was suspended beneath the sea ice of
Colby Bay, T-3,...
Summer brooding often requires some form of air modification in
addition to maximizing ventilation rate to prevent animal heat stress
and possible death due to hyperthermia. A rockbed thermal storage
module was designed and constructed to provide sensibly cooled air
for a broiler space under summer brooding conditions. A mathematical...
The purposes of this study were first to determine if there were significant differences
in living environment press, i.e., the pressure on an individual to behave in a
certain way, between those fraternity chapters that had the highest freshman pledge
retention rates and those that had the lowest. If significant...
Cardiovascular disease (CVD) is the leading cause of mortality in the United States (US) and research suggests that CVD morbidity and mortality disproportionately impacts Asian American and Native Hawaiian and Pacific Islander (NHPI) older adults. However, the prevalence on CVD and underlying mechanisms for CVD disparities among disaggregated Asian American...
