Resumen
HpUreI is a pH-gated urea channel found in the pathogenic bacterium Helicobacter pylori. This protein is an essential component of the mechanism of acid acclimation, which allows Helicobacter pylori to survive in the acidic conditions of the stomach. HpUreI conducts urea into the cytoplasm, where it is hydrolyzed by urease into carbon dioxide and ammonia. These products then transit back into the periplasm, where they function as a buffer and proton consumer respectively. HpUreI is an attractive target for small molecule inhibitors for the treatment of H. pylori infections as mutant strains la

The experiments used a number of gas compositions to simulate different combustion exhaust gases. The urea was injected into the gases as a urea-water solution. The decomposition processes of the urea-water solutions and urea powder were examined. For both the nitric oxide removal and the urea decomposition experiments, a Fourier transform infrared (FTIR) spectrometer was used to determine the concentrations of the product species.

Resumen
Nitrogen is an essential plant nutrient in the biosphere. Although N is necessary and beneficial for life, it is also a common pollutant in the atmosphere and hydrosphere as it may be lost to the atmosphere as ammonia (NH3) or nitrous oxide (N2O) gases or to groundwater as nitrate (NO3-) following fertilization. Polymer coated urea (PCU) is one type of N fertilizer which uses temperature-controlled diffusion to control N release to better match plant demand and mitigate environmental losses of N. The objectives of this project were to simultaneously compare the effects of PCU on gaseous (as N2

Resumen
Nitrogen (N) is the most commonly over-applied nutrient in urban environments because of the large visual and growth increases. This over-application has led to an increase in the loss of N gas in the forms of ammonia and nitrous oxide, as well as an increase in nitrate leaching to surface and groundwater. Furthermore, excess N results in increased maintenance costs and landfill volume due to increased shoot growth from mowed clipping removal. Polymer coated urea (PCU) has proven to be an excellent source to these losses of N to the environment, but rate and timing parameters need study. A two

Urea synthesis and alanine oxidation were measured in skate (Raja erinacea) hepatocytes incubated with pharmacological doses of four hormones: insulin, glucagon, 1α-OH, and 1,2-dehydro-A. Peptide hormones were used only for short (2.25 hours) incubations, while incubations with steroids were 2.25, 24, or 48 hours. None of the hormones exerted any effects on urea synthesis or alanine oxidation during the shortest incubation period, however after 24 hours 1α-OH caused a significant (p<.05) elevation in alanine oxidation, which may be an adaptive response of skates to dilute seawater.

This research presents a viability assessment of using urea as an energy vector.

Urea is cheap to produce and has an existing manufacturing infrastructure, but it also has a huge untapped natural resource, of which this study found that the knowledge to extract was technically attainable.

Resumen
It is well known that folded proteins in water are destabilized by the addition of urea. When a protein loses its ability to perform its biological activity due to a change in its structure, it is said to denaturate. The mechanism by which urea denatures proteins has been thoroughly studied in the past but no proposed mechanism has yet been widely accepted. The topic of this thesis is the study of the mechanism of urea-induced protein denaturation, by means of Molecular Dynamics (MD) computer simulations and Nuclear Magnetic Resonance (NMR) spectroscopy.

Diesel engines produce large amounts of nitrogen oxides (NOX) while running. Nitrogen oxides are highly toxic and also contribute towards the formation of tropospheric ozone. Increasingly stringent legislation regarding the amount of nitrogen oxides that are allowed to be emitted from diesel-powered vehicles has forced manufacturers of diesel-engines to develop after-treatment systems that reduce the amount of nitrogen oxides in the exhaust. One of the main components in such a system is selective catalytic reduction (SCR), where nitrogen oxides are reduced to diatomic nitrogen and water with

Resumen
4 pp.<br>Nitrogen fertilizer is normally applied later in the season around flowering time to boost grain protein content. The purpose of this study is to determine if the grain protein boost provided by late N application is affected by method of application. A trial testing late season N application methods was conducted at the Maricopa Ag Center in the 2016 growing season. The crop was grown 211 lb N/acre in split applications until flowering when 35 lb N/acre was applied as UAN32 in the irrigation water (fertigation), as low biuret urea in a foliar application, or as urea granules compared
