Algal biomass production and nutrient removal from high strength anaerobic digestate
(2022-04-29)
The integration of microalgal biomass production with nutrient removal from the liquid portion of anaerobic digestate holds the potential to close the loop on waste. However, algal growth inhibition in anaerobic digestate ...
Anthropogenic and Climate Impacts on Groundwater Resources in the Lower Apalachicola-Chattahoochee-Flint River Basin
(2015-01-07)
El Niño Southern Oscillation (ENSO) is one of the major climate variability cycles around the world and is responsible for droughts in the Southeast United States. These ENSO-induced droughts have been responsible for ...
Biochemical production from engineered Bacillus species
(2023-12-12)
Microbial production of biochemicals has gained significant attention due to increasing global concern regarding the depletion of fossil resources. As prominent workhorses in microbial fermentations, Bacillus species have ...
Biocrude production from biomass and mixed plastics via hydrothermal liquefaction for fuel and chemicals
(2022-12-05)
Hydrothermal liquefaction (HTL) is a promising technology to convert organic feedstocks into value-added fuel precursors known as biocrude, solids (hydrochar), and gaseous byproducts. The HTL process can efficiently break ...
Biofuel Production from Hydrothermal Liquefaction of Algae and Its Subsequent Upgrading
(2017-11-30)
Algae are considered as a promising feedstock for biofuel production. The conversion of algae to biofuel was investigated in this study. The study was concentrated in two main areas: hydrothermal liquefaction of algae into ...
Biomass Gasification for Power and Fuel Applications using a Bench-Scale Bubbling Fluidized Bed Gasifier
(2015-05-18)
Today fossil fuels are a major source of energy. Coal is used extensively around the world for power applications, while petroleum products are used to fulfill liquid fuel needs. This extensive use of fossil fuels has led ...
Boom Dynamics during Control System Response on Agricultural Sprayers
(2011-12-05)
Farm managers use highly productive and mechanized agricultural sprayers to efficiently cover cropland. These sprayers use modern control systems including automatic section control (ASC) capabilities to manage target ...
Catalytic Pyrolysis of Thermally Pre-treated Biomass for Aromatic Production
(2013-07-10)
Torrefaction, a biomass pre-treatment process, is considered to be a promising way to improve biomass properties, aiding in producing highly deoxygenated biofuel. Among several techniques available to convert biomass to ...
Characterization of Biofuels Produced from Hydrothermal Liquefaction of Algae, Its Subsequent Upgrading and Fractional Distillation
(2018-11-16)
Crude petroleum is the major source of transportation fuels in the world whose reserves are declining day by day. It has become imperative to look for an alternative that can either replace or substitute the current energy ...
Characterization of PLA-PHB Based Active Packaging Film, and Its Application on Oysters
(2017-11-20)
Biodegradable material polylactic acids (PLA) and polyhydroxybutyrate (PHB) were designed as the matrices for active food packaging applied on oysters. In this study, the performance of bioplastics was first evaluated ...
Climate Change Implications on Rainfall Erosivity and Intensity Duration Frequency Curves over the Southeast United States
(2023-08-04)
Climate change impacts on precipitation characteristics will alter the hydrologic characteristics, such as peak flows, time to peak, and soil erosion potential. However, many of the currently available climate change ...
Climate Variability and Irrigation Impacts on Stream-Aquifer Dynamics in the Apalachicola-Chattahoochee-Flint River Basin
(2015-08-18)
Climate variability cycles are responsible for short term fluctuations in climatic conditions thereby, affecting the water cycle and the availability of freshwater resources around the world. In Southeast United States, ...
Comparing Economic Returns of Dissolved Oxygen Management in Commercial Catfish Production
(2016-05-02)
Catfish culture is one of the largest forms of aquaculture in the US. Catfish production systems have been able to achieve production up to almost 12,000 kg ha-1 year-1 (Bott, 2015) since the increase in availability of ...
Comparison between Radio Frequency (RF) and Traditional Heating Assisted Alkaline Pretreatment on Lignocellulosic Biomass
(2015-07-30)
Pretreatment plays an important role in making the cellulose accessible for enzyme hydrolysis and subsequent conversion because it more or less destroys resistance and recalcitrance of biomass. In this study, radio frequency ...
Comprehensive utilization of microalgae (Chlorella vulgaris) and the application of its product
(2019-12-05)
Rapid growth, fixation of carbon dioxide, and little competition with food plus some species possessing high lipid content make microalgae a suitable feedstock to produce biodiesel. However, high cost related to dehydration, ...
Contribution of Particle Size and Moisture Content to Flowability of Fractionated Ground Loblolly Pine
(2014-05-20)
The use of woody biomass requires feedstock materials in particulate form; therefore there is a need for size reduction of the feedstock materials. Ground biomass typically has a non-uniform particle size and as a biological ...
Developing and Optimizing Micro-resolution Mosquito Bite Blocking Textiles
