Agrobacterium rhizogenes has been shown to cause root
proliferation and increased water use efficiency in
certain woody dicots. Root proliferation may be desirable
in herbaceous legumes as a means of increasing potential
sites for infection by Rhizobium species and subsequent
nodulation and nitrogen fixation. Thus, A. rhizogenes was
used to...
Present day data processing technology requires very high speed signal processing and data conversion rates. One such application which requires high speed is switched capacitor circuits used in Sigma-Delta modulators. A major active component of switched capacitor circuits is the monolithic operational amplifier(opamp). Because of the relatively poor speed performance...
Here the diversity and phylogeny of the genus, Sthereus Motschulsky, 1845, and its nearest associates in the large subfamily Molytinae are explored through molecular and morphological characters. Sanger sequencing of five genes determined that Sthereus is not monophyletic. Instead, the one species in the genus Gastrotaphrus Buchanan 1936, G. barberi...
A more quantitative understanding of peptide entrapment and elution from otherwise protein-repellent polyethylene oxide (PEO) brush layers will provide direction for development of new strategies for drug storage and delivery. Here we describe criteria for peptide integration and structural change within the PEO brush, and discuss the reversibility of peptide...
The COVID-19 pandemic has shed a light on the need for people to trust in medical science. With the need for 70% of Americans to be vaccinated to achieve herd immunity but 30% have reported vaccine hesitancy, now more than ever do we need to redouble our efforts to ensure...
On June 23, 2016 the United Kingdom (UK) held a vote to determine whether to remain in the European Union (EU) or withdraw. The British exit from the EU, or Brexit, is the antithesis of two centuries of progressive social work theory developed by a series of prominent social workers...
It is often noted that young adults tend to be apathetic towards involvement in the political process. The aim of this study is to scratch the surface of this phenomena and, in a scientific fashion, begin to discover if this can be changed. In the study, press releases from members...
Availability of evergreen forage plants during the
two dry seasons in arid central Somalia is very important.
Cordeauxia edulis is a multistemmed evergreen legume shrub
which grows in Central Somalia in plant communities
dominated by deciduous shrubs. There are two growth forms
of this plant. A form with small leaflets...
California and Steller sea lions (Zalophus californianus, Eumetopias jubatus, respectively) are considered sentinel species because they have long life spans, are long-term coastal residents, feed at high trophic levels, and have large blubber stores that serve as depots for anthropogenic toxicants. There are few studies on sea lion health and...
Sotalol is a class III anti-arrhythmic drug with class II properties that is commonly used in the treatment of ventricular tachyarrhythmias in dogs. The anti-arrhythmic effects of sotalol are mediated by an increase in action potential duration and prolongation of atrial and ventricular repolarization via antagonism of the delayed rectifier...
Parasites are ubiquitous members of ecological communities, capable of contributing to the decline of vulnerable populations. Therefore, monitoring parasite level is a critical component for host management. Molecular tools, such as quantitative polymerase chain reaction (qPCR), can be valuable additions to monitoring protocols that assess parasitic disease risk to hosts....
The advent of improved DNA sequencing technologies has allowed the analysis of various microbial communities. Bloom-forming freshwater cyanobacteria can produce toxins and taste-and-odor compounds that can negatively affect drinking water supplies. Here, I have employed second- and third-generation sequencing technologies to characterize bloom-forming freshwater cyanobacterial genomes and their associated heterotrophic...
There exists a variety of methods to solve the radiation transport equation in stochastic materials, including the Levermore-Pomraning method and the atomic mix method, each of which is designed to replicate the results given by benchmarks with materials rearranged in a randomized fashion. While the atomic mix method is very...
Zinc oxide nanoparticles (ZnO NPs) have demonstrated the ability to improve lubrication and thermal conductivity, and stand as promising metalworking lubricant and coolant additives due to their low cost compared to other NPs. While nanomaterials are a focus of research due to their potential to enable advanced technologies, little is...
A review of current computer performance and evaluation techniques reveals a lack of an acceptable analytic tool for optimal computer system performance and evaluation. A generalized approach to the formulation of a third generation computer system model is proposed. The approach is used to optimize computer resource utilization and to...
Germinating seeds often encounter stress conditions
of temperature, moisture and oxygen in the field.
Germination tests conducted under these stress conditions
in the laboratory might be methods of differentiating high
and low vigor seeds.
The objectives of this study were to (1) determine
if these stress conditions reduce germination performance...
This research involves a numerical study of the
hydrodynamics of gas fluidized beds. We use the continuum
model, treating both gas and particles as
interpenetrating continua. The motion of gas and
particles is strongly coupled by the interactions between
them. For simplicity, we only consider drag forces.
We use MacCormack's...
