Mutlu, Atilla (2009-05-15)There is a need for a robust and accurate technique to measure ammonia (NH3) emissions from animal feeding operations (AFOs) to obtain emission inventories and to develop abatement strategies. Seasonal studies were conducted ...
-
DeOtte, Robert Eugene (Texas A&M University. Libraries, 1986)A laser Doppler velocimeter was used to measure three components of velocity in the body of an 88.9 mm diameter, multiport, reverse flow sampling cyclone with a flat bottom. This velocity data was then nondimensionalized ...

Faulkner, William B. (2010-01-16)Over a fourth of the cotton produced in the US since 2002 has been produced in Texas, with most coming from the High Plains. In recent years, Texas has accounted for almost half of all US cotton production (USDA-NASS, ...
-
Nunneley, Jacob Lawrence (2013-04-22)With recent genetic advances in development of gossypol-free cotton varieties, there is interest in retrieving undamaged, dehulled cottonseed kernels for development of new food and feed products. Current methods used to ...

Faulkner, William Brock (Texas A&M University, 2006-08-16)Cyclone separators are widely used in agricultural processing industries as air pollution abatement devices. The performance of cyclones is a function of the geometry of the cyclone, operating parameters, and the particle ...
-
Powell, Jacob Joseph (2009-05-15)Non-road diesel engines are significant contributors to air pollution in the United States. Recent regulations put forth by EPA and other environmental agencies have laid out stringent guidelines for engine manufacturers ...
-
Hamm, Lee Bradford (Texas A&M University, 2006-04-12)An engineering analysis of the fugitive particulate matter emissions from a feedyard is not simple. The presence of an evening dust peak in concentration measurements downwind of a feedyard complicates the calculation of ...
-
Lange, Jennifer Marie (Texas A&M University, 2008-10-10)The EPA press release dated February 23, 2004 states that the three Buckeye Egg Farm facilities had the potential to emit more than a combined total of 1850 tons per year of particulate matter (PM). This number was based ...
-
Sarwar, Ghulam (Texas A&M University. Libraries, 1988)Corn (or Maize) kernels may develop stress cracks due to internal stresses when subjected to moisture adsorbing or desorbing environments. Kernels with stress cracks break more readily than sound kernels during handling ...
-
Guha, Abhinav (2010-07-14)Previous studies have demonstrated that EPA approved federal reference method (FRM) samplers can substantially misrepresent the fractions of particles being emitted from agricultural operations due to the relationship ...
-
Evaluation of PM10 and Total Suspended Particulate Sampler Performance Through Wind Tunnel Testing Thelen, Mary Katherine (2011-10-21)Particulate matter (PM) concentrations in ambient air can be monitored by gravimetric sampling near a source using Federal Reference Method (FRM) samplers. PM is regulated by size, with PM10, which is comprised of particles ...
-
Piumsomboon, Pruchya (Texas A&M University. Libraries, 1981)This dissertation presents a new discrete/continuous digital simulation language. GEMS-D/C, a Generalized Manufacturing Simulator, is designed to assist system analysts investigating complex manufacturing systems with a ...

Hamann, Mark Thomas (2012-02-14)There are currently two main types of machinery used for harvesting cotton in the United States, cotton pickers and cotton strippers with or without field cleaners. These different machine types package seed cotton with ...
-
Ge, Yufeng (2009-05-15)The overarching goal of this dissertation project was to address several fundamental aspects of applying site-specific crop management for fiber quality in cotton production. A two-year (2005 and 2006) field study was ...
-
Capareda, Sergio Canzana (Texas A&M University. Libraries, 1990)Conditions for the optimal production of activated carbon from biomass waste through thermal gasification techniques were studied in this research. Operation of the Biomass Thermal Conversion System (BTCS) gasifier at ...
-
Lepori, Wayne A.; Parnell, Calvin B. (United States. Patent and Trademark Office; Texas A&M University. Libraries, 1989-07-18)A system is disclosed for converting unconditioned biomass, such as cotton gin trash, into usable energy. This is accomplished by gasifying the biomass, removing the particulate char from the combustible gas using cyclonic ...
-
Wang, Lingjuan (Texas A&M University, 2005-08-29)To design a cyclone abatement system for particulate control, it is necessary to accurately estimate cyclone performance. In this cyclone study, new theoretical methods for computing travel distance, numbers of turns and ...
