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 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
(2015-01-07)
Soil erosion on unprotected roadside slopes generates significant soil loss during storm events. Proper surface protection to reduce erosion is promoted by water protection agencies including the United States Environmental ...
Effects of growth-promoting bacteria in suspended green algae cultures for bioenergy and bioproduct development
(2020-07-14)
With the exhaustion of fossil-based fuels, microalgae have attracted great interest as a renewable energy feedstock. Microalgae are photosynthetic microorganisms with rapid growth and the potential for production of lipids, ...
Effects of tillage practices and cover crops on X-ray computed tomography derived soil pore characteristics
(2023-08-02)
Soil management practices such as conservation tillage and cover crops improve soil health and crop yield. However, these practices may create connected soil pore networks that can cause preferential transport of contaminants ...
Engineering Clostridium saccharoperbutylacetonicum for Enhanced Isopropanol-Butanolethanol (IBE) Production from Lignocellulosic Biomass through Acetic Acid Pretreatment
(2018-07-25)
The objective of this study was to achieve efficient biofuel production from lignocellulosic biomass through the development of a novel biomass pretreatment method in combination with the metabolic engineering of microbial ...
Engineering Comfort for Micro-resolution Mosquito Bite Blocking Textiles
(2023-04-24)
Over a million people die yearly from diseases spread by biting insects, especially mosquitos. Pesticides are currently used to control harmful insect populations although there are often negative side effects from pesticides. ...
Enhancement of Nutrient and Organic Removal from Poultry Litter Using Anaerobic Digestion and Subsequent Algal Growth
(2019-07-12)
Research has indicated anaerobically digesting poultry litter can recover energy and reduce pathogen concentrations, which can be used as a nutrient rich media to support algal growth and simultaneously further treat the ...
