The Phenomenological Unveiling
(2017-05-05)
As humans, we often experience the world around us solely through our eyes, which has hindered us in designing. This is not to state that all human senses are not important, but rather to point out that our potential to ...
Phenotypic and Genetic Aspects of Fertility in Beef Heifers
(2019-07-17)
Reproductive success of a heifer’s first breeding season is highly critical to the sustainability of beef cattle production systems. Therefore, multiple management practices exist to ensure heifers are properly developed ...
Phonological Awareness in Mandarin of Chinese and Americans
(2009-04-17)
Phonological awareness (PA) is the ability to analyze spoken language into its component sounds and to manipulate these smaller units. Literature review related to PA shows that a variety of factor groups play a role in ...
Phonological Awareness Skills of Six-year-old Children with Mild and Moderate Articulation Disorders
(2006-05-15)
An investigation of the phonological awareness skills of children with mild and moderate articulation disorders is presented in this thesis. A sample of 24 first graders, 12 of whom had normal articulation and the other ...
Phosphatic Concretions and Ichnofossil Preservation in a Marine Lagerstätte, Ripley Formation, Central Alabama
(2006-05-15)
Phosphate concretions are common in the Upper Cretaceous Ripley Formation exposed along Dry Cedar Creek, Lowndes County, Alabama. Sedimentologic and ichnologic studies of concretions and host sediments were undertaken to ...
Phosphite in Soil and Turfgrass
(2016-04-26)
Phosphate, derived from phosphoric acid (H3PO4), has long been used as a P fertilizer source, while phosphite, derived from phosphorous acid (H3PO3), has long been used as a known and proven fungicide. However, the exact ...
Phospho-silicate glass as gate dielectric in 4H-SiC metal-oxide-semiconductor devices
(2016-07-28)
Silicon carbide (SiC) based MOS devices are well suited to meet the need for energy efficient power electronics. For 4H-SiC MOSFET technology, one of the crucial challenges is to improve the quality of SiO2/SiC interface, ...
Phosphodiesterase 5 Inhibition on Dopaminergic and Glutamatergic Neurotransmission: Implications for Memory Enhancement
(2009-02-06)
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 ...
