A New Species Of Chevalia From The Caribbean Sea (Crustacea: Amphipoda), J. L. Barnard, James Darwin Thomas

Marine & Environmental Sciences Faculty Articles

A new Caribbean species, Chevalia carpenteri is described; heretofore only one species of the genus was known, but we have examined material that suggests morphs may represent distinct species or subspecies. We report C. mexicana and extend its range from the northern Gulf of Mexico to Belize. Our new species differs from the world complex of C. aviculae morphs in the ovate article 2 of pereopods 5-7 and the posteriorly flat epimera with large notches.

Marine & Environmental Sciences Faculty Articles

Audulla chelifera Chevreux is reported for the first time outside of the Indian Ocean and Red Sea. It has now been found in the western Caribbean inhabiting the alga Turbinaria turbinata (Linneaus) Kuntze in backreef regions of the Belize barrier reef.

Detection Of Elastin, Collagen, And Cartilage Particles In Ground Beef By Enzyme Digestion And Sensory Analysis, G. Whipple, J.B. Axe, S. Goll, Curtis L. Kastner

Kansas Agricultural Experiment Station Research Reports

An enzyme digestion technique was developed using a proteolytic enzyme concentrate to quantitate connective tissue particles in ground beef samples, which had been formulated to contain various amounts of connective tissue. Replicate samples were also evaluated by a taste panel to quantify detectable connective tissue particles. Results for the laboratory enzyme technique and the taste panel were highly correlated. Therefore, the enzyme digestion technique can be used to estimate total connective tissue in ground beef and those particles that are detected upon chewing.

Effect Of Environmental Temperature And An Inoculant On The Fermentation Of Forage Sorghum Silage, K. Bolsen

Kansas Agricultural Experiment Station Research Reports

The inoculants, BioPower®, increased the rate and efficiency of ensiling in Acco Paymaster 351 forage sorghum regardless of storage temperature. The untreated, 60 F silage fermentated slower and had higher pH, lower lactic acid, and higher acetic acid values than its 90 F counterpart.

Grazing And Feedlot Performance Of Heifers Spayed By Two Methods, S.B. Laudert, Gerry L. Kuhl, A.J. Edwards

Kansas Agricultural Experiment Station Research Reports

Two field trials were conducted to compare the pasture and finishing performance of heifers spayed by the Kimberling-Rupp(K-R) technique or by flank spaying plus autografting a piece of ovarian tissue into the rumen wall (FS+A). In trial 1, neither spaying method resulted in gains of grazing heifers different from that of intake controls; however, FS+A heifers gained 5.1% faster than K-R spayed heifers. In trial 2, grazing gains of heifers spayed by the two techniques were similar. During the finishing phase, no performance difference was found among intact, K-R, or FS+A heifers in trial 1 or between K-R and FS+A …

Effect Of Stocker Receiving Diet On Subsequent Pasture Gains, F. Brazle, Gerry L. Kuhl, D. Harmon

Kansas Agricultural Experiment Station Research Reports

Seven diets were fed for 27 days to newly arrived heifers to evaluate their impact on stocker gains during the receiving and pasture periods. The diets were as follows: soybean hulls plus soybean meal; suncured alfalfa plus wheat middlings; dehydrated alfalfa plus grain sorghum; distillers dried grain plus cottonseed hulls; brome hay plus 2 lb protein supplement/day; prairie hay plus 2 lb protein supplement/day; and a commercial receiving ration. During the receiving period, diets of soybean hulls plus soybean meal, distillers dried grain plus cottonseed hulls, and the commercial receiving ration produced the highest cattle gains. The soybean hull plus …

Effect Of Supplemental Protein:Energy Ratio On The Intake, Digestibility, Fill, And Turnover Of Dormant Bluestem Range-Grasses, T. Delcurto, R.C. Cochran, K.A. Jacques, D.L. Harmon, G. Towne, T.B. Avery, E.S. Vanzant

Kansas Agricultural Experiment Station Research Reports

Feeding a low crude protein (12%) supplement depressed dormant bluestem range-grass fiber digestibility, whereas moderate (27%) and high (41 %) protein supplementation maintained forage digestibility and encouraged intake. Increased intake for moderate and high protein groups appeared to be associated with increased rumen dry matter and indigestible fiber fill.

Influence Of Prebreeding Progesterone Plus Prostaglandin F2-Α On Estrus And Fertility In Lactating Dairy Cows (1987), M.O. Mee, R.E. Stewart, Jeffrey S. Stevenson, Edward P. Call

Kansas Agricultural Experiment Station Research Reports

Progesterone administered before breeding may increase estrous expression and subsequent fertility in lactating dairy cows. Holstein cows (n=302) were assigned randomly at calving to three groups. Cows received no treatment (controls), one injection of prostaglandin F 2-α (PGF), or progesterone plus one injection of PGF (PRID + PGF). The average interval to estrus was 5 days shorter in PRID + PGF cows compared to cows given only PGF. In addition, more cows were observed in estrus 2 to 5 days after treatment in the PRID + PGF group compared to the PGF group. Average days from calving to conception were …

Use Of Extruded Soy Flour In Milk Replacers For Calves (1987), D.P. Dawson, J.L. Morrill, P.G. Reddy, Keith C. Behnke

Kansas Agricultural Experiment Station Research Reports

Oil-extracted, desolveritized soy flour without additional heat treatment was used to prepare protein supplements for calf milk replacers by extrusion processing. Various combinations of temperature, moisture, calcium concentration, sulfur, and acid were used to prepare 32 different products. These products were tested for trypsin inhibitor and antigenic activity and the most promising one was chosen for further testing. This product alone or with supplementary amino acids or amino acids and citric acid was used to provide 70% of the protein in experimental milk replacers. These replacers were compared to an all-milk replacer, using growth and metabolic responses of young Holstein …

Early Lactation Somatic Cell Count Should Be Low (1987), James R. Dunham

Kansas Agricultural Experiment Station Research Reports

Cows and heifers in milk for fewer than 50 days, as shown on the DHIA Somatic Cell Count report, should have a lower average Somatic Cell Count than cows in milk for more than 300 days, if the dry cow mastitis treatment and management programs are effective. The DHIA Somatic Cell Count (SCC) average for a dairy herd is a good evaluation of a mastitis control program. Since leucocytes migrate to the mammary system during periods of subclinical mastitis, the SCC average indicates the amount of subclinical mastitis in a herd. A realistic goal for a herd average SCC is …

Cow-Side Milk Progesterone Testing, Edward P. Call, Jeffrey S. Stevenson

Kansas Agricultural Experiment Station Research Reports

Cow-side milk progesterone tests are effective in determining the presence of an active corpus luteum (CL) on the ovary. The test is best used as an adjunct to the Preventive Herd Health Program (PHHP) as a means of identifying cows that have not yet been detected in heat and are candidates for synchronization with prostaglandin (PGF). Several test kits are on the market, and all involve similar chemical principles. However, each test has its own protocol, so read and follow directions EXACTLY. A "control" or "sample" must be run with each test for comparison.; Dairy Day, 1987, Kansas State University, …

The Effects Of Xanthine And Adenosine Analogs On Rat Pup Diaphragmatic Contractility, Liam C. Farrell

Masters Theses

Methylxanthines are commonly used in the treatment of respiratory disorders such as asthma, apnea of prematurity and Cheyne-Stokes respiration. Recently, certain methylxanthines have been found to potentiate the contraction of the diaphragm and increase contraction strength of the fatigued diaphragm. The mechanism of action of the methylxanthines is unknown. Three theories have been proposed but each has its supportive and negative points. One theory is that methylxanthines inhibit cyclic AMP phosphodiesterase (PDE) which facilitates contraction by increasing cyclic AMP levels in the cell. Another theory is that methylxanthines antagonize adenosine, thus blocking the adenosine-induced inhibition of contraction. The third theory …

The Effects Of Xanthine Analogs On Neonatal Rat And Adult Mouse Respiration, Susan M. Reynolds

Masters Theses

Apnea, a prolonged cessation of breathing, is commonly seen in premature infants. This condition, in its severest form, can be lethal and is a suspected cause of sudden infant death syndrome (SIDS). Sometimes referred to as apnea of prematurity, recurrent apnea is presently being treated with respiratory stimulants known as methylxanthines (MX) such as theophylline and caffeine. The benefits of MXs are accompanied by central nervous system stimulation and cardiostimulation which may be detrimental to a premature infant. Theophylline (1,3-diMX) has been shown to produce some of its effects by antagonizing endogenous adenosine. Another xanthine, enprofylline (3-propylxanthine), is presently being …

Some Potential Evolutionary Costs Associated With Paternal Care In The Water Bug Belostoma Flumineum Say, Larry Johnson

Masters Theses

Female water bugs (Belostoma flumineum) deposit eggs in a mucilaginous cement on the back of conspecific males, who then brood these eggs until hatching. Sex role reversal, in which females compete for males and males are discriminating, is predicted in this species because males provide parental care exclusively, and represent a limited resource. Presumably the advantage of this paternal behavior is increased survival of young. However, the potential exists for this egg-brooding behavior to incur evolutionary costs, and quantifying some of these costs was the thrust of this study.

One cost, a loss of polygynous opportunity, was investigated …

Cyanogenic Plants Of Illinois, Kevin E. Aikman

Masters Theses

Cyanogenesis in 50 species of vascular plants collected from east central Illinois was studied by examining 10 populations of each species. Each population consisted of 30 individuals, which gave an over all sample size of 300 plants per species. Herbarium specimens from the Stover Herbarium of Eastern Illinois University (EIU) were also tested for the presence of cyanide. More than 20,000 specimens were tested for this study which included cultivated plants, introduced weeds, and native plant species. The speed and degree of the HCN reaction as well as the specific plant part tested were included to give a more specific …

A Taxonomic Re-Evaluation Of Specimens Of The Genus Caloplaca In The E.L. Stover Herbarium Of Eastern Illinois University, Eric J. Cameron

Masters Theses

The genus Caloplaca is the largest genus in the family Teloschistaceae. The 103 species in the genus greatly outnumber any other in the family. Lichens of the genus Caloplaca are usually orange to orange-yellow in color, and range from crustose to subfoliose in form. The orange color is due to an anthraquinone, parietin, the location of which is taxonomically important in this genus of lichens. In some species it occurs only in the apothecia, while in others it is found in both the apothecia and thallus. The spores of this genus are polarilocular, and the width of the isthmus is …

The Effects Of Frozen Storage And Repeated Freeze-Thawing On Salmonella In Varied Concentrations Of Waste Activated Sludge, Joseph Toman Jr.

Masters Theses

Commonly, waste activated sludge is applied to farmland as a fertilizer supplement and soil conditioner. The use of waste activated sludge is not only an efficient way of sludge disposal, but also an economical one. Much concern has been raised about the safety of such a practice. Harmful pathogens, like Salmonella, are commonly present in waste material. Treatment at wastewater plants is successful in eliminating these organisms from final effluent, but the solids generated are full of indigenous microorganisms, including Salmonella.

Work of this paper attempts to determine the safety of the sludge product after simulated winter conditions …

A Woody Understory Survey Of Baber Woods, Edgar County, Illinois, Jacqueline M. Spencer

Masters Theses

The understory of Baber Woods, located in Edgar County, Illinois, was surveyed to see if sugar maple had increased enough in importance to consider implementing some type of forest management technique. Five 100 meter transects were randomly located in closed canopy areas throughout the woods. Specimens were removed from continuous 1 meter quadrats located along each line. Specimens were also removed from twenty 25 meter transects located in the open canopy areas. Species, age, height, diameter, and quadrat number were recorded for each specimen. The data was analyzed for age-height and age-diameter relationships, plus individuals per hectare, density, frequency, relative …

Microsurgical Fertilization Of Mammalian Eggs: An Assessment Of Clinical Utilization, Susan E. Lanzendorf

Theses and Dissertations in Biomedical Sciences

Microsurgical fertilization is the technique in which a spermatozoon or sperm nucleus is injected into the cytoplasm of an egg. To establish a foundation for the use of microsurgical fertilization as a means of treating infertility, this study evaluated the procedure in hamster and human eggs. Hamster sperm nuclei were microinjected into hamster eggs to determine the rate of abnormal fertilization and to ultrastructurally assess cellular damage by transmission electron microscopy. Hamster eggs were also injected with human spermatozoa obtained from fertile and infertile men to evaluate the fertilizing potential of the sperm cells. In addition, human eggs donated by …

Biochemical And Histological Evaluation Of Normal Human Epidermis Vs Cultured Human Epidermis, Ngo Thi Bich Lien

Biological Sciences Theses & Dissertations

Cultured human keratinocytes were grown in vitro for transplantation purposes in case of severe burns. Single keratinocytes were harvested from human epidermis and grown in culture flasks such that multilayered sheets of keratinocyte cells were harvestable in approximately three weeks. In order to evaluate cultured epidermis for equivalency with normal human epidermis, biochemical and histological studies were performed. Thin sections of cultured epidermis were shown to be composed of cells that had undergone developmental differentiation, but not terminal differentiation. Biochemical analyses of keratin and prekeratin proteins isolated from cultured epidermis indicated that cultured keratinocytes have electrophoretic patterns similar to keratins/prekeratins …

Isolation And Characterization Of Vinclozolin-Resistant Mutants Of Neurospora Crassa, Kimberly Booth Thurmon

Legacy ETDs

Six vinclozolin-resistant mutants of N. crassa obtained following ultraviolet irradiation and selection on vinclozolin media, showed 1:1 segregation of the vinclozolin-resistant trait. In addition to being vinclozolin resistant, the six mutants had altered, non-wild-type morphology and were osmotic sensitive, with the different mutants exhibiting varying degrees of sensitivity. Genetic analysis indicated linkage of the three traits. Reappearance of osmotic sensitivity/altered morphology in crosses of phenotypically recombinant F₃ progeny supported the presence of modifier(s). Rates of growth on vinclozolin media placed the six mutants into three groups. In most cases the rates were comparable to rates of growth on W-M …

Spermatogenesis In The Mosquito Eretmapodites Quinquevittatus, Robert Daniel Hunter Jr.

Legacy ETDs

Various stages of spermatogenesis in pupal testes of the mosquito Eretmapodites quinquevittatus (Theobald) were determined by 2% 1acto-aceto-orcein and silver nitrate staining techniques. Temporal relationships of stages were demonstrated and behavior and appearance of meiotic chromosomes were described.

Pupal testes were most active meiotically for the first 12-14 hours after onset of pupation. The prepachytene stage of leptotene and a nucleolus were observed with the use of silver nitrate staining. Experimental observations demonstrated the first spermatids and visible mature sperm at 6-8 and 18 hours, respectively, after onset on pupation. E. quinquevittatus mean sperm size was reported (head = 50 …

The 20-Hz Signals Of Finback Whales (Balaenoptera Physalus), William Watkins, Peter Tyack, Karen Moore, James Bird

James E Bird

The 20-Hz signals of finback whales (Balaenoptera physalus) were analyzed from more than 25 years of recordings at a variety of geographic locations on near-surface hydrophones close to whales and on deep hydrophone systems. These signals were composed of 1-s pulses of sinusoidal waveform with downward sweeping frequency from approximately 23 to 18 Hz at variable source levels up to 186 dB (re: 1 microPa at 1 m), usually with slightly lower levels for the pulses at the beginning and end of sequences. These "20-Hz" pulses were produced in signal bouts (separated by more than 2 h) lasting as long …

Genetic Compatibility Of Aedes (Protomacleaya) Triseriatus With A. (P.) Brelandi And A. (P.) Hendersoni (Diptera: Culicidae)., David B. Taylor

David B. Taylor

Interspecific hybridization was used to examine reproductive compatibility of Aedes (Protomacleaya) triseriatus (Say) with Aedes (P .) brelandi Zavortink and Aedes (P.) hendersoni Cockerell. Most male progeny were sterile intersexes when A. brelandi or A. hendersoni males were crossed with A. triseriatus females. Female hybrids, and males from the reciprocal crosses, were morphologically normal and fertile. Varying percentages of intersex males were observed among progeny when normal F₁ hybrids were crossed to either parental species or with other hybrids. Egg and female sterility resulting from a partial incompatibility between A. triseriatus cytoplasm and …
