Biomass Gasification for Power and Fuel Applications using a Bench-Scale Bubbling Fluidized Bed Gasifier 

Kulkarni, Avanti (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 

Sharda, Ajay (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 

Srinivasan, Vaishnavi (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 

Jain, Nikhil (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 

Miao, Luoqi (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 Variability and Irrigation Impacts on Stream-Aquifer Dynamics in the Apalachicola-Chattahoochee-Flint River Basin 

Singh, Sarmistha (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 

Holland, Leigh Wilson (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 

Wang, Xiaofei (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 

Ma, Yichao (2019-12-05)  ETD File Embargoed
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 

Oginni, Oluwatosin Jerry (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 

Holt, John (2022-04-25)  ETD File Embargoed
Textiles have been applied in the context of entomological applications since the primitive inventions of clothing and shelter. In many cases insects are injurious to humans. Mosquitos kill over a million people each year ...
