Effect Of Sprinkling On Heat Stressed Heifers, Shane Davis, Terry L. Mader, John Gaughan

Nebraska Beef Cattle Reports

Six heifers were housed in controlled environmental stalls. All heifers were sprinkled with water between 1300 - 1500 hours for three days followed by a two-day period in which three were sprinkled between 1200 - 1600 hours and three were not. This was followed by a one day hot period during which all heifers were sprinkled (1300 - 1500 hours). Rectal temperature and respiration rate were reduced in all animals during the first three days of heat stress. On days four and five, heifers sprinkled four hours had lower rectal temperature, respiration rate and pulse rate than heifers which were …

Replacement Heifer Development For Spring And Summer Calving Herds, Gene H. Deutscher, Brent Plugge, Andy Applegarth, Rex Davis

Nebraska Beef Cattle Reports

A three-year study on heifer development of spring-born (n=240) and summer-born heifers (n=146) was conducted using sandhills ranch management. Spring-born heifers developed during the winter to reach 53% of mature weight at breeding had similar reproduction and calf production as heifers that reached 57% of mature weight. Feed costs were $22/heifer less for the lighter weight heifers. Summer-born heifers that were developed to reach 60% of mature weight at breeding in early fall had normal yearling pregnancy rates, but rebreeding rates of the 2-year-old cows were low, which caused high culling rates. Two-year-old cows calving in May produced greater calf …

Urinary Allantoin As An Estimate Of Microbial Protein Synthesis, Mariela Lamothe, Terry J. Klopfenstein, Don C. Adams, Jacqueline A. Musgrave, Galen E. Erickson

Nebraska Beef Cattle Reports

Allantoin excretion in the urine was evaluated as a marker for bacterial protein production in lactating and dry cows grazing Sandhills range and meadows. Allantoin excretion declined with season as diet digestibility declined. Bacterial protein predicted from allantoin was significantly related (R2 = .62) to bacterial protein predicted by NRC. Urinary allantoin has potential as a tool to predict bacterial protein production in grazing cattle.

Ompd But Not Ompc Is Involved In Adherence Of Salmonella Enterica Serovar Typhimurium To Human Cells, Bochiwe Hlezipi Hara-Kaonga

Doctoral Dissertations

Salmonella enterica serovar Typhimurium expresses three major outer membrane proteins: OmpC, OmpF, and OmpD. Conflicting reports exist regarding the role of OmpC and OmpD in the pathogenesis of this organism. This study investigated the role of OmpC and OmpD in adherence to human U937 macrophages and T84 intestinal epithelial cells. OmpC and ompD mutant strains were created by transposon mutagenesis utilizing P22-mediated transduction of Tn10 and Tn 5 insertions into wild-type strain 14028. Fluorescein-labeled wild-type and mutant bacteria were incubated with PKH26-labeled T84 cells at various bacteria-to-cell ratios for 1 h at 37 C. Single and dual fluorescence of samples …

Community And Ecosystem Analysis Of Forests Recovering From Landslide Disturbance: White Mountain National Forest, New Hampshire, David M. Bryant

Doctoral Dissertations

Sites recovering from landslide disturbance offer many opportunities to study ecosystem processes under extreme conditions. Landslides reset the topographic, microclimatic, parent material and vegetation state factors of ecosystem development. Water, and nutrient resources following landslides are more heterogenously distributed. Soil structure and development is disrupted. Solar insolation and diurnal temperature fluctuation exceed that of the surrounding forest. Consequently, plant colonization and community succession differ from less severely disturbed sites such as timber harvest or agricultural afforestation.

Two chapters of this dissertation address the unique conditions of landslide ecosystem development. Chapter 2 compares historical data collected in 1956 on a chronosequence …

Implementation And Evaluation Of Group -Based Prevention Of Eating Concerns Using Self -Efficacy And Knowledge Enhancement, Lindsey Erin Laplant

Doctoral Dissertations

The project implemented and evaluated a prevention program for eating concerns with first year college women. Two prevention conditions were examined. One condition provided information about eating concerns, from definitions to biopsychosocial risks and consequences. The second condition built self-efficacy and skills in the participants along with presenting information. The evaluation component was unique compared to other evaluations in the eating concerns prevention literature. It used pre and post intervention assessments, a control group, and had a larger sample of participants compared to other similar published programs. Both quantitative and qualitative assessment techniques were used to evaluate participants' experience in …

Expression, Activation, And Regulation Of Matrix Metalloproteinase 2 (Mmp-2) In The Bovine Corpus Luteum, Bo Zhang

Doctoral Dissertations

Matrix metalloproteinases (MMPs) have been postulated to be important for angiogenesis and for tissue remodeling events associated with corpus luteum (CL) development. The MMPs are mainly regulated at three levels, transcription, activation, and inhibition by endogenous tissue inhibitors of metalloproteinases (TIMPs). Unlike most MMPs, pro-MMP-2 activation is accomplished on the cell surface rather than extracellularly. The objectives of the present study were to clone bovine cDNAs for MMP-2 and its activator, membrane type 1- (MT 1-)MMP, to investigate the expression and localization of MMP-2, MT1-MMP, TIMP-1, and TIMP-2 in three ages of CL, and to explore the regulation of MMP-2 …

Genetic Basis Of Adaptive Radiation In East African Cichlids, Richard Craig Albertson

Doctoral Dissertations

East African cichlids are a paramount example of adaptive morphological radiation. The most dramatic difference among species occurs in oral jaw design and correlates with ecological niche partitioning. Convergent evolution of trophic forms between lakes suggests a common mechanism. What combination of intrinsic and extrinsic factors constitute this mechanism still remains to be seen. The goal of this dissertation was to examine the genetic basis of shape differences between two closely related cichlid species that employ alternate modes of feeding. This was achieved through a number of independent experiments. First, I used field data to characterize the way in which …

Depressive Symptomatology Among Dominicans: Links To Acculturative And Economic Stressors, Skin Tone, And Perceived Discrimination, Teresita Camacho-Gonsalves

Doctoral Dissertations

Latinos have been identified as a population at high risk of developing mental health problems. However, studies on Latinos rarely address differences between subgroups. There are important social and cultural differences between subgroups that are likely to be reflected in differential expressions of depressive symptoms. The fast growing Dominican community in the United States is one subgroup of Latinos that has been understudied and underserved.

The objectives of this dissertation were to explore among Dominicans: (1) the direct and indirect effects of sociodemographic factors and skin tone on psychological distress; (2) the relationships between various stressors (economic, perceived discrimination, and …

The Effects Of Erythrocyte Alloantigen L On The Avian Immune Response, Zdravka Ognyanova Medarova

Doctoral Dissertations

Experiment 1 examined the alloantigen system L effects on Rous sarcomas in three B complex genotypes. The parental stock were 50% Modified Wisconsin Line 3 and 50% inbred Line 6.15- 5. B2B5 L1L2 x B2B5 L 1L2 matings produced experimental chicks. Chicks were inoculated with 20 pock-forming units (pfu) Rous sarcoma virus (RSV) at 6 weeks-of-age. Tumors were scored six times over 10 weeks postinoculation. Tumor scores were used to assign a tumor profile index (TPI) to each chicken. Results were evaluated by ANOVA. The B complex affected the responses. Separate analyses revealed L system effects ( P < 0.05) only in B5B 5 chickens.

Experiment 2 …

Life History Dynamics Of Nudibranch Sibling Species In The Genus Dendronotus In The Gulf Of Maine, Chad Gordon Sisson

Doctoral Dissertations

Two different larval types have been described for the nudibranch Dendronotus frondosus (Ascanius, 1774) in the Gulf of Maine. A taxonomic review of adults with planktrophic larvae and those with lecithotrophic larvae revealed regular differences in radula morphology, and no predictable differences in the reproductive system. These data and previous data on a behavioral reproductive isolation mechanism suggest a new species designation for populations of Dendronotus with lecithotrophic larvae. Laboratory studies were used to compare the larval dispersal potential of the two types of Dendronotus. D. frondosus planktotrophic larvae had a potential planktonic period of approximately 11 weeks at 10°C …

A Gender And Development (Gad) Implementation Evaluation: Testimonios Reveal The Successes, Challenges, And Unpredicted Results For Women's Equality And Community Sustainability, Melinda Salazar

Doctoral Dissertations

This is a case study of a Gender and Development implementation evaluation in several rural, Baha'i communities in Andean Bolivian. "Traditional Media as Change Agent," funded by UNIFEM (UN International Fund for Women) and implemented by BIC (Baha'i International Community), was an innovative, non-economic approach to change gender attitudes and behaviors by including men in a consultative process using traditional media. This study responded to criticism that GAD ignored the environment, was lodged squarely in Western economic development thought and Western feminist values, and lacked the voices of the women and men for whom development aims to benefit.

Further Remarks On Risk Sources Measuring: The Case Of A Life Annuity Portfolio, Mariarosaria Coppola, Emilia Di Lorenzo, Marilena Sibillo

Journal of Actuarial Practice (1993–2006)

The paper considers a model that allows the actuary to measure the riskiness connected to the randomness of projected mortality tables in evaluating a portfolio of life annuities, obtaining a measure to reflect the risk associated with the randomness of the projection. The coherence of the risk parameters with the specific nature of the considered risk sources is also discussed. Numerical examples illustrate the results, showing the importance of the risk components in terms of the number of policies and comparing measure tools obtained by means of two procedures.

Clinical Evaluation Of Optic Atrophy In Patients With Neurological Disorders, Fadhil Abbas, Akram M. Al-Mahdawi, Ali A. Ali

Neurosciences

OBJECTIVE: Optic atrophy is a pathological term applied to optic nerve shrinkage from any process that produces degeneration of axons in the anterior visual system (the retino-geniculate pathway). The pathologist can make the diagnosis of optic atrophy by direct observation of the histopathological changes in the optic nerve. The clinician is restricted to indirect evidence by observing the optic nerve as it enters the eye and through testing its function. METHODS: Fifty patients with bilateral or unilateral optic atrophy, were collected randomly from several teaching hospitals in Baghdad, Iraq, between August 1998 and June 1999. Those patients included in this …

Ecological Health Movement In Lebanon : An Overview Of Alternative Culture In A Developing Country, Mark Perry

Journal of Ecological Anthropology

An ecological health movement has emerged in Lebanon in reaction to problems in the mainstream health care system, to environmental conditions affecting agriculture and food sources, and to urbanization. The movement parallels similar developments in other countries. It depends primarily on practitioners of macrobiotics and organic agriculture, and is centered on the belief that good health is obtained through observance of dietary rules requiring consumption of organic food. The practice of these rules necessitates in Lebanon a reversal of trends toward centralization and urbanization in order to reestablish ties between consumers and farmers. It also implies a renaissance of organic …
