Phosphodiesterases belongs to a family of proteins that metabolize cyclic nucleotides. There are at present eleven types of Phosphodiesterases been isolated and shown to be expressed in various tissues. Phosphodiesterase ...
Phospholipid/Aromatic Thiol Hybrid Bilayers
(2016-12-09)
Gold-supported hybrid bilayers comprising phospholipids and alkanethiols have been found to be highly useful in biomembrane mimicking as well as biosensing ever since their introduction by Plant in 1993 (Plant, A. L. ...
Phosphorus and nitrogen budget for inland, saline water shrimp ponds in Alabama
(2012-11-08)
Phosphorus and nitrogen budgets were prepared for ponds in an inland low-salinity shrimp farm in the Blackland Prairie region of Alabama. The study was conducted during the first crop in three ponds which were newly ...
Phosphorus Characterization of Alabama Soils and Evaluation of Extractants for Environmental Phosphorus Loss Risk Assessment
(2020-08-03)
Poultry industry is the second largest agricultural industry in Alabama and generates 1.5 million tons of poultry litter, which contains approximately 19,000 tons of phosphorus (P). Long term application of fertilizers and ...
Phosphorus in Aquaculture Ponds: Controlling Technique and its Bioavailability to Cyanobacteria
(2023-04-28)
Understanding the loading, speciation, and bioavailability of phosphorus (P) in aquaculture ponds is important for controlling P and harmful algal blooms. This thesis first explored flue-gas desulfurization (FGD) gypsum ...
Phosphorus Nutrition of Pecan
(2018-04-24)
A fundamental component of pecan management is maintaining phosphorus (P) nutrition throughout the tree’s growth, development and production. Pecans have difficulty maintaining adequate P concentrations when managed for ...
Phosphorylation of fetuin-A, a physiological inhibitor of insulin action, regulated by insulin and leptin
(2007-05-15)
Fetuin-A, a liver secreted phosphoprotein and rat homologue of human a2-HS-glycoprotein (AHSG), is a physiological inhibitor of insulin action. Fetuin-A-null mice exhibit improved glucose tolerance and resistance to weight ...
Photo-assisted Adsorptive Desulfurization of Hydrocarbon Fuels over TiO2 and Ag-TiO2
(2016-05-05)
Organic sulfur compounds are one of the most common impurities in crude oil which is widely used as transportation fuels such as gasoline, diesel and jet fuels. Sulfur in liquid hydrocarbon fuels is also considered as one ...
Photodissociation dynamics of vibrationally excited hydrogen molecules examined with reaction microscopy in kinematically complete VUV + NIR experiments
(2023-12-04)
Using the Cold Target Recoil Ion Momentum Spectroscopy (COLTRIMS) technique, we investigated the dissociation of vibrationally excited H₂ and D₂ molecules after two-color vacuum ultraviolet (VUV) + near-infrared (NIR) ...
Photoreduction of Chlorinated Organic Pollutants Using Solutions or Films of a Polymeric System via a Free Radical Mechanism
(2018-07-27)
Efficient reduction of chlorinated organics took place upon exposure to 350 nm photons in aqueous solutions containing sulfonated poly(ether etherketone), SPEEK, and either poly(vinyl alcohol), PVA, or HCO2H/HCO2- buffers. ...
