Application Performance of Unmanned Aerial Systems (UAS) for Seeding Cover Crop
(2026-04-19)
The use of unmanned aerial systems (UAS) for applying dry solid products, especially cover crop seed, has increased rapidly in the United States in recent years. Limited information currently exists on the application ...
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 and Modeling of Temporal Illuminance (Light Intensity) in Naturally-Illuminated Broiler Houses
(2025-07-10)
Lighting plays an important role in the welfare, behavior, and productivity of broilers. This thesis investigates the influence of seasonality, sensor orientation and window configurations on light intensity in commercial ...
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 ...
