Development of spray drying technology for microencapsulation of bioactive materials
(2015-12-10)
Lipophilic bioactive components, such as carotenoids, have received increasing attention in food and pharmaceutical industries because of their potential health benefits. They have been recognized to exhibit physiological ...
Drought Forecasting for Small to Mid-sized Communities of the Southeast United States
(2012-05-07)
Most of the climate variability in the Southeast United States has been attributed to El Niño Southern Oscillation (ENSO) and this climate variability has resulted in increased the stress on water resources of the region ...
Effect of animal manure application and soil physicochemical properties on nutrient and metal leaching
(2023-08-07)
A significant amount of poultry litter produced in the southeastern United States is applied to pasture lands. Poultry litter application on agricultural lands can cause nutrient enrichment of subsurface effluent, particularly ...
Effect of biomass variability on catalytic fast pyrolysis to produce renewable transportation fuels
(2016-12-12)
The paradigm shift in recent years towards the use of renewable sources of energy to fuel economies around the world is primarily due to the limited availability of conventional sources such as fossil fuels, coal and ...
The Effect of Grid Resolution on Hydrodynamic Modeling of Biscayne Bay
(2024-01-08)
Environmental Fluid Dynamics Code Plus (EFDC+) is a model that has been proven to be effective in hydrodynamic simulation. Understanding water surface elevation (WSE) and salinity dynamics in estuaries is crucial for ...
Effect of Poultry Litter and Biochar Application Methods on Nutrient Loss
(2024-07-29)
High levels of phosphorus (P) and trace metals, such as copper (Cu) and zinc (Zn), can cause significant water quality issues when delivered to water bodies. This study investigated the impact of different poultry litter ...
Effect of substratum topography on algal turf colonization and productivity under different nutrient conditions
(2016-07-28)
Algae can act as a promising source for biofuel production, pollution recovery from natural waters and nutrient recovery from wastewaters. Typical algae cultivation involves algae in the suspended form, and separation ...
Effect of Torrefaction on Biomass Structure and Product Distribution from Fast Pyrolysis
(2015-01-13)
Torrefaction, a thermal pretreatment process, has been documented to improve the chemical composition of bio-oil produced from fast pyrolysis process. During torrefaction pretreatment, the major constituents of biomass ...
Effect of vane shape and fertilizer product on spread uniformity using a dual-disc spinner spreader
(2014-06-27)
Advancements in granular applicators are required in order to provide accurate metering and placement of fertilizer as emphasis grows on nutrient and associated environmental stewardship. Spinner-disc spreaders are commonly ...
Effectiveness of selected erosion control covers during vegetation establishment under simulated rainfall
