(Texas A&M University. Libraries, 1989)Cellulase was immobilized on magnetite particles with a polymer spacer. Several methods of immobilization were investigated for optimizing enzyme activity of the immobilized cellulase (IMC). The optimum method involved the ...
-
(Texas A&M University. Libraries, 1989)Pretreatment of biomass has been shown to increase the efficiency of microbial conversion of lignocellulose to energy or chemicals. Most chemical and physical pretreatments, however, are too expensive for practical ...
-
(Texas A&M University. Libraries, 1992)Computer algorithms were developed for generating the guidance parameters necessary to steer an agricultural tractor in field operations. A variety of operations were considered in order that the guidance program be general ...
-
(Texas A&M University. Libraries, 1987)Image processing algorithms were developed and tested for computing a guidance signal for an agricultural tractor traveling on row crops. Field images of various row crops were recorded on videotape with a tractor-mounted ...
-
(Texas A&M University. Libraries, 1986)Method of characteristics (MOC) solutions are widely employed in solute transport models of groundwater to estimate tracer concentration. The conventional approach to obtain average tracer concentration for the cell is to ...
-
(Texas A&M University. Libraries, 1988)Tests were conducted with vertical drop test equipment, in order to assess the damage inflicted on subterranean agricultural products, by the use of an impact separator. The previously designed impact separator removes ...
-
(Texas A&M University. Libraries, 1989)A rap id rate nitrification filter, called a retained biomass disk (RBD). has been used to examine the response of Nitrosomonas spp. to different levels of nitrite (14- 196 mg-N/L) an d the response of Nitrobacter spp. to ...
-
(Texas A&M University. Libraries, 1982)Two dimensional soil moisture flow was studied. A laboratory model 1.83 meters long and 0.13 meters wide, 1.22 meters deep at one end and 0.91 meters deep at the other end was used to generate experimental data consisting ...
-
(Texas A&M University. Libraries, 1978)The disposal of cotton gin waste from the gin site has become an economic factor in the efficient operation of a cotton gin. Energy costs are rising and the possibility of curtailment of energy supplies, primarily natural ...
-
(Texas A&M University. Libraries, 1992)Ultimate tensile and compressive strengths, corresponding moduli of elasticity, and compressive stress relaxation properties (relaxation time constants) of parboiled brown rice were investigated. Samples were prepared from ...
-
(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 ...
-
(Texas A&M University. Libraries, 1986)A three-parameter model was developed to evaluate the parameters (K, a, and F) in the extended Kostiakov infiltration equation when continuous flow irrigation is practiced. The model also permits the evaluation of the ...
-
(Texas A&M University. Libraries, 1988)A simulation model of hourly rainfall amounts was developed to provide hourly precipitation input to a water balance model. The hourly rainfall model consists of four parts: (1) daily rainfall occurrence, (2) event rainfall ...
-
(Texas A&M University. Libraries, 1990)A dryer prototype was built based on commercial natural convection dryers using agricultural waste as the energy source. In addition, a pre-conditioning plenum was built to control the humidity and temperature of input ...
-
Generalized kinetics of ethanol fermentation and ethanol production in a Ca-alginate plate reactor (Texas A&M University. Libraries, 1989)Ethanol from renewable sources has great potential for the alternatives of fossil fuels and commodity chemicals. Increasing the efficiency of ethanol fermentation processes and using low cost and stable feedstocks can make ...
-
(Texas A&M University. Libraries, 1991)Infiltration in irrigated furrows is a complex hydraulic phenomenon that varies in both space and time. The effects of spatially variable infiltration on advance and infiltration of water along a furrow must be well ...
-
(Texas A&M University. Libraries, 1990)ADD ABSTRACT
-
(Texas A&M University. Libraries, 1988)Three methods of sensing the positions of components of a multi-jointed mobile truss structure and transmitting this information with single bit data to a controller were proposed. A control algorithm utilizing the single ...
-
(Texas A&M University. Libraries, 1987)A combined analytical and experimental approach was used to develop the equations of motion of a 1/6 scale cable drawn model disk harrow. The lateral deviation was found to be a linear combination of the lateral force ...
-
(Texas A&M University. Libraries, 1987)A secondary water recovery operation was proposed in order to recover additional amounts of water stored in the unsaturated zone of depleted aquifers and currently unavailable with conventional techniques. The proposed ...
