Algin/Calcium Gels In Solid-Muscle Structured Beef Steaks, Roger C. Johnson
Electronic Theses and Dissertations
Alteration of the inherent characteristics of less preferred beef carcass portions to produce products with greater consumer appeal has been the ultimate goal of structured meat research. Consumer acceptance of structured products has been limited because of (1) low retail visibility, (2) diet/health concerns due to salt addition, and (3) undesirable uncooked product appearance due to discoloration and lack of fiber orientation. Development of solid-muscle structured products would alleviate these limitations and the negative influence the less desirable carcass portions have on total carcass value. Efficacy of a binding gel containing various concentrations of algin/calcium (Alg/Ca) and adipic acid (Ad) …

Older sows consumed ten percent more feed than younger sows. Older sows returned to estrus after weaning approximately two days sooner than younger sows. Based on swine performance of this two-year study, neither drip cooling or zone cooling systems should be installed in areas with …
The Fast Hartley Transform On A Parallel Processor, Boon Pock Lim
The Fast Hartley Transform On A Parallel Processor, Boon Pock Lim
Electronic Theses and Dissertations
In 1942, Hartley proposed a new formulation of the Fourier integral identity by using cas (wt) as the transform kernel, where cas(wt) = cos(wt) + sin(wt), is an abbreviation for cosine and sine. It is called the Hartley transform and has many properties similar to those of the Fourier transform. The important distinctions are that the Hartley transform of a real-valued function is also real valued, and the inverse transformation is operation as the direct transformation. the same integral Furthermore, its evaluation does not involve complex functions. This is a potential advantage if the transform is to be explicitly computed. …

In Vitro Rescue Of Helianthus Annuus Embryos By Ovule Culture, John C. Volin
Electronic Theses and Dissertations
Interspecific hybridization between the cultivated sunflower, Helianthus annuus L., and other Helianthus species is an important aspect of sunflower improvement, because it extends the array of genes available for use in breeding programs. Sunflower species have demonstrated resistance to many pests that affect the cultivated sunflower. Oil content and quality may also be improved through interspecific hybridization, as Helianthus species are sources of genetic variation for these traits. Attempts to cross H. annuus with sixteen other Helianthus species were only 40 % successful. It is generally assumed that failure of interspecific hybridization in sunflowers is due to abortion of the …

Parallel Processing Of The Fast Fourier Transform, Ke Zhou
Electronic Theses and Dissertations
The first FFT algorithms were reported by Runge and Konig in 1924, and by Danielson and Lanczos in 1942. However, the FFT didn't receive much attention at all until Cooley and Tukey published their algorithm in 1965. The Cooley-Tukey algorithm is simple and widely used in many application software packages. Winograd developed his FFT in 1976, which is based upon the prime factor theory. It is typically faster than the Cooley-Tukey Algorithm, if the computer system has no multiplication instructions. According to the book prepared by the Digital Signal Processing Committee of the IEEE in 1979, the speed difference among …

Control Of Downy Brome With Combinations Of Bay-Smy-1500 And Metribuzin, James R. Smart
Electronic Theses and Dissertations
Downy brome (Bromus tectorum L.) is a severe weed problem in winter wheat (Triticum aestivum L.) throughout North America. Downy brome competes for space, light, nutrients in the soil, and most importantly moisture. Rydrych reported that a grower with reasonable control of downy brome can increase yield of winter wheat 6-12 bushels per acre. The lack of selective herbicides which control downy brome in winter wheat and conservation tillage practices have contributed to the spread of downy brome. Some herbicides labeled for downy brome control in winter wheat require incorporation. Incorporation of herbicides may not be compatible with reduced or …
