Asas Centennial Paper: Net Energy Systems For Beef Cattle – Cattles, Application, And Future Models, Calvin Ferrell, J. W. Oltjen

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Development of nutritional energetics can be traced to the 1400s. Lavoisier established relationships among O₂ use, CO₂ production and heat production in the late 1700s, and the laws of thermodynamics and law of Hess were discovered during the 1840s. Those discoveries established the fundamental bases for nutritional energetics and enabled the fundamental entity ME = retained energy + heat energy to be established. Objectives became: 1) to establish relationships between gas exchange and heat energy, 2) to devise bases for evaluation of foods that could be related to energy expenditures, and 3) to establish causes of energy expenditures. …

Chapter 4. Relationship Of Environmental Nitrogen Metabolism To Human Health, J. R. Follett, R. F. Follett

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The need for humans to produce and consume food and other agricultural products is increasing. This need is directly related to increasing world populations, demands for goods and services, and expectations. Nitrogen (N) is contained in all of the amino acids and proteins in the foods consumed by humans. The use of N to produce food and other products is generally increasing as human needs increase. Proteins are an essential component of the human diet because, unlike plants, humans are unable to utilize more simple forms of N and rely on food sources for protein which can then be digested …

Effect Of Sample Processing Procedures On Measurement Of Starch In Corn Silage And Corn Grain, M. B. Hall, D. R. Mertens

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Methods for processing feedstuffs before analysis can affect analytical results. Effects of drying temperature (corn silage), preservation method (corn grain), and grinding method (corn silage and grain) on starch analysis values were evaluated. Corn silage samples dried at 55 or 105°C and grain samples dried at 55°C were ground to pass the 1-mm screen of an abrasion mill or cutting mill and analyzed for free glucose and starch corrected for free glucose. Starch analyses were performed in triplicate to assess the effect of treatment on precision of starch determination. Drying at 105°C decreased free glucose and tended to decrease starch …

Initial Response Of Evapotranspiration From Tallgrass Prairie Vegetation To Co2 At Subambient To Elevated Concentrations, H. W. Polley, H. B. Johnson, P. A. Fay, J. Sanabria

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

A series of weighing lysimeters in which tallgrass prairie species had been planted were exposed to a subambient to elevated gradient in CO₂ in a field chamber. Lysimeters with intact monoliths of three soil types were represented along the CO₂ gradient. We used regression analysis to determine how CO₂ effects on evapotranspiration per unit of soil surface area (ET_soil) and per unit of leaf area (ET_la) depended on variation in leaf area index (LAI) and diurnal changes in environmental variables during the initial 6 weeks of CO₂ treatment.

Growth And Feed Efficiency Of Juvenile Channel Catfish Reared At Different Water Temperatures And Fed Diets Containing Various Levels Of Fish Meal, Menghe H. Li, Edwin H. Robinson, Brian C. Peterson, Terry D. Bates

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Channel catfish Ictalurus punctatus do not feed well at low temperatures. It is generally thought that a diet containing fish meal enhances feed palatability at low temperatures since fish meal is highly palatable to fish. There is a lack of information on the effects of fish meal levels on the growth performance of channel catfish reared at low temperatures. Therefore, a study was conducted in a recirculating system to examine the effects of fish meal levels on the feed consumption, weight gain, and feed efficiency of juvenile channel catfish reared at various temperatures. Fish with an initial weight of 9.6 …

Vogel, Cesar Heraclides Behling Miranda

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

In the early 1970's research was initiated by the cooperative USDA-ARS and University of Nebraska grass breeding program to develop perennial grasses adapted to the mid-continental USA with improved forage quality. The initial breeding and animal evaluation work focused on switchgrass (Panicurn virgatum) but has since expanded to several other warmand cool-season perennial grasses. The in vitro dry matter digestibility (IVDMD) test was selected as the measure of forage quality that was used in the breeding work because of its previous successful application on improving bermudagrass (Cynodon dactylon). In all of the grass species that we …

How Stigma Affects Information Sharing By Gay Men And Glbt Communities, Kathryn Shephard

Electronic Theses and Dissertations

This study examined how stigma and dialectical tensions affect information sharing by gay men. One specific area that was investigated is the use of interpersonal boundary spanning techniques in managing information related to being gay. The research used a qualitative, interpretive method to gather and analyze data from eleven in-depth interviews. An interview schedule was developed based on the critical incident technique in order to focus the interviews on specific events and direct observation. The questions in the interview covered individuals experiences with sharing their sexual orientation with someone else for the first time, times when they have specifically chosen …

Enteric Bacteria Of Field-Collected Colorado Potato Beetle Larvae Inhibit Growth Of The Entomopathogens Photorhabdus Temperata And Beauveria Bassiana, Michael B. Blackburn, Dawn E. Gundersen-Rindal, Donald C. Weber, Phyllis A. W. Martin, Robert R. Farrar Jr.

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The nematode Heterorhabditis marelatus fails to reproduce in the Colorado potato beetle, Leptinotarsa decemlineata, possibly due to interference from the enteric bacteria of the beetle. Specifically, the enteric bacteria inhibit the growth of Photorhabdus temperata, the enteric symbiont of the nematode, in vitro. However, previous work was based on a laboratory culture of L. decemlineata, and we wished to determine if similar bacteria were present in the field. Therefore, we cultured the enteric bacteria of fourth-instar larvae collected from the field at two locations in Maryland and Virginia. Representatives of the genera Pantoea, Enterobacter, Pseudomonas …

The Effect Of Two Types Of Recovery On The Decline In Performance After Intense Bouts Of Exercise, Whitney Shindelar

Honors Program Theses

Anyone who is recreationally active, whether an athlete or someone in the general population, has some preferred action they choose to engage in after an extensive bout of intense exercise. According to Comparison of Two Strategies on Recovery after Exhausting Exercise, the common recommendation of raising your arms above your head in order to recover more quickly and thoroughly has been shown to not be the optimal recovery mechanism. The previously mentioned study has recently shown that a subject's heart rate decreased dramatically faster, which then decreased their over all recovery time, when they opted to bend at the …

An American's Guide To Cultural Brokering, Jessica Anna Sauer

Honors Program Theses

The United States is the world's largest refugee host, welcoming almost 3 million people in the last 30 years, according to the January 16th, 2007 edition of the San Francisco Chronicle. In addition to refugees, the United States accepted 1,266,264 immigrants in 2006, as stated in the Office of Immigration Statistics 2006 Yearbook of Statistics. Furthermore, the Kids Count Data Center reports that one out of every five children lives in an immigrant family. Clearly, these numbers show that immigrants compose a significant part of our communities.

While the US strives to welcome newcomers, many immigrants are left in the …

Health Equity, Hpv And The Cervical Cancer Vaccine, Joanna Erdman

Articles, Book Chapters, & Popular Press

This article explores the relationship between technological innovation and health inequity. It examines in particular the relationship between the vaccine against human papillomavirus (HPV) infection, the cause of cervical cancer, and inequity in cervical cancer incidence and mortality. In Canada, screening programs have drastically reduced the incidence of cervical cancer, but their benefits have been unequally distributed. Prevention efforts have disproportionately failed women of disadvantaged social groups. Technological innovation alone will not remedy this inequity. The HPV vaccine merely expands the available means for reducing or increasing health inequity depending on its implementation. For this reason, the article looks beyond …

Amp-Activated Protein Kinase Is Involved In Hormone-Induced Mouse Oocyte Meiotic Maturation In Vitro, Jing Chen, Stephen M. Downs

Biological Sciences Faculty Research and Publications

We have previously shown that AMP-activated protein kinase (AMPK) can induce the resumption of meiosis in mouse oocytes maintained in meiotic arrest in vitro. The present study was carried out to determine whether AMPK activation is involved in hormone-induced maturation. Follicle-stimulating hormone (FSH) and the EGF-like peptide, amphiregulin (AR), are potent inducers of maturation in cumulus cell-enclosed oocytes (CEO). Within 3 h of FSH treatment, phospho-acetyl CoA carboxylase (ACC) levels were increased in germinal vesicle (GV)-stage oocytes when compared to non-stimulated controls and remained elevated throughout 9 h of culture, indicating AMPK activation. A similar response to AR was observed …

Landscape And Traffic Factors Influencing Deer–Vehicle Collisions In An Urban Enviroment, Janet W. Ng, Charlene Nielsen, Colleen Cassady St. Clair

Human–Wildlife Interactions

Deer–vehicle collisions (DVCs) are steadily increasing across North America. The increase is particularly pronounced in urban green spaces where deer (Odocoileus spp.) populations and road densities are high. In the greater city of Edmonton, Alberta, Canada, 333 DVCs occurred from 2002 to 2004. To identify landscape and traffic correlates of these collisions, we built 3 statistical models. The first model assessed the importance of local variables and was based on a spatial precision of the nearest intersection to which collisions were referenced. The second model was based on landscape characteristics and used the nearest township intersection to aggregate collisions. …

Deer–Vehicle Collision Prevention Techniques, Lauren L. Mastro, Michael R. Conover, S. Nicole Frey

Human–Wildlife Interactions

Every year in the United States approximately 1.5 million deer–vehicle collisions (DVCs) occur resulting in >29,000 human injuries, >200 human fatalities, 1.3 million deer fatalities, and >1 billion dollars worth of property damage. Despite the magnitude of this problem, there are relatively few well-designed studies that have evaluated techniques that can be used to reduce DVCs. Techniques to reduce DVCs fall into 4 categories: reducing the number of deer (Odocoileus spp.), reducing the number of vehicles, modifying deer behavior, and changing motorist behavior. Techniques to reduce the number of deer include decreasing the deer population or excluding deer from …

Gnrh Immunocontraception Of Male And Female White-Tailed Deer Fawns, Lowell A. Miller, James P. Gionfriddo, Jack C. Rhyan, Kathleen A. Fagerstone, Donald C. Wagner, Gary J. Killian

Human–Wildlife Interactions

Immunocontraceptive vaccines based on gonadotropin-releasing hormone (GnRH) have been tested in adult white-tailed deer (Odocoileus virginianus), but their effects on fawns are unknown. The purpose of this study was to determine if early immunization against GnRH would induce a long-lasting immune response in fawns, and if it would delay or prevent sexual development. We gave primary and subsequent booster injections of a KLH-GnRH/Freund’s vaccine to 6 male and 6 female fawns. This vaccine contained the same active ingredients as GonaCon™ vaccine, but it contained Freund’s adjuvant instead of AdjuVac™ adjuvant. Two 450-μg injections were given 1 month apart …

Demographics Of Non-Hunted White-Tailed Deer Populations In Suburban Areas, Anthony J. Denicola, Dwayne R. Etter, Thomas Almendinger

Human–Wildlife Interactions

Burgeoning deer populations in urban and suburban areas, along with the inherent problems stemming from this increase, are becoming increasingly widespread. To address these problems, wildlife biologists need quality baseline data of herd composition for harvest and treatment forecasts for management and fertility control research programs. In this study, we provide white-tailed deer (Odocoileus virginianus) population data from 4 areas where localized suburban white-tailed deer populations were substantially reduced utilizing sharpshooting as a management tool. In each area, legal hunting was nonexistent for >10 years preceding the sharpshooting program. The areas ranged in size from 300 ha to …

Role Conflict, Role Ambiguity And Job Satisfaction Of The Nurse Executive, Theresa Ann Tarrant

UNLV Retrospective Theses & Dissertations

Healthcare organizations have seen remarkable and unprecedented changes over the past two decades. Political and social expectations have risen, drastic changes in payer systems have lead to a focus on controlling costs and profitability and technology and research has exploded. As a result, the role of the Nurse Executive (NE) has expanded significantly. At the same time, the United States is currently undergoing a major nursing and faculty shortage. According to a 2003 study, the average age of a NE is 49 years (Ballein Search Partners, 2003) with many expected to retire over the next 12 years. The potential exists …

Interleukin-10 Inhibits Cytokine-Mediated Synergistic Release Of Interleukin-6 In Astrocytoma Cells, Liliya V Harizanova

UNLV Retrospective Theses & Dissertations

Astrocytes respond to pro-inflammatory cytokines such as, interleukin-1 (IL-1beta) and tumor necrosis factor (TNF-alpha). However, the mechanisms in which IL-1beta and TNF-alpha mediate cell's signaling need further investigation; In previous research, the effects of y-aminobutyric acid (GABA) on IL-1 and TNF-alpha signaling pathway were studied. GABA was unable to suppress IkappaB-alpha degradation and the phosphorylation of p38 by IL-1beta and TNF-alpha. However, it was suggested that GABA may be able to inhibit IL-6 release by reducing the rate of IkappaB-alpha degradation; Another cytokine, IL-10, which is well known in literature to have anti-inflammatory effects, is investigated in this study. This …

Optimal Foraging Theory And Early Archaic Plant Use At North Creek Shelter, Sara C Hill

UNLV Retrospective Theses & Dissertations

Optimal Foraging Theory has received considerable intellectual criticism since its use as an archaeological tool for understanding human behavior. In this thesis, I will evaluate Optimal Foraging Theory with an empirical test from North Creek Shelter, an archaeological site located in the Escalante Basin on the northern portion of the Colorado Plateau. This test will focus on plant utilization by the early Archaic occupants of the site. An environmental reconstruction for the Escalante Basin will be used to determine the range and quantity of plant resources available to the early Archaic occupants of North Creek Shelter. Then a botanical assemblage …

The Effects Of Cryotherapy On Eccentric Peak Torque Recovery After An Intense Eccentric Exercise, Michelle Nicole Peluaga

UNLV Retrospective Theses & Dissertations

This study investigated the effects of a 45-minute cryotherapy application post-exercise repeated daily for 3-days on the recovery of the quadriceps after inducing DOMS. Results showed eccentric mean PT was greater at baseline than 24-hours after eccentric exercise. Knee AROM, joint line, 5cm, and 10cm girth measurements resulted in no differences. However, 15cm and 20cm sites revealed baseline values being lower than 48-hours; Tenderness at VMO post-treatment resulted in a difference with the initial application being lower than 24-hours. The 15cm site pre-exercise and post-treatment resulted in differences where baseline was lower than 24 and 48-hours. Post-exercise revealed the treated …

Skeletal Muscle Damage, Delayed Onset Muscle Soreness And Performance After Resistance Training With Leucine And Carbohydrate Or Carbohydrate Alone, Matthew Steven Stock

UNLV Retrospective Theses & Dissertations

The purpose of this study was to evaluate the efficacy of adding leucine to pre and post-exercise carbohydrate beverages on blood markers of muscle damage, muscle soreness, and squat performance. Eighteen resistance-trained subjects performed 6 sets of squats to fatigue using 75% of the 1-RM with 3 minutes rest between sets. Subjects consumed a carbohydrate beverage (.25 g/kg) 30 minutes before and immediately after exercise with or without the addition of leucine (45 mg/kg) in randomized, double-blind fashion. Creatine kinase (CK), lactate dehydrogenase (LDH), and subjective surveys of muscle soreness, were analyzed before, 24 hrs, 48 hrs, and 72 hrs …

UNLV Retrospective Theses & Dissertations

This study explored whether university students enrolled in health science classes were able to estimate their energy requirements within a range of calories equal to predicted Estimated Energy Requirements (EER) +/- two standard deviations. The International Physical Activity Questionnaire (IPAQ) and a participant survey were given to a convenience sample of 63 male and 92 female undergraduate students (19-23 years) with subsequent measurements of height, weight and body fat percentage. Results from the IPAQ yielded metabolic equivalents which were converted to physical activity coefficients for use in the EER equation. Students significantly underestimated their EER by an average of 700 …

Sex And The Agricultural Transition: Dental Health Among Early Agricultural Females, Misty Fields

UNLV Retrospective Theses & Dissertations

This project analyzed dentition from a sample (n =142) of Early Agricultural period skeletons (B.C. 1600-200 A.D.) from the site of La Playa (SON F:10:3), Sonora, Mexico. Data was collected on pathology rates for dental caries and antemortem tooth loss (AMTL) to test the hypothesis that hormone-fluctuations associated with pregnancy increase dental pathology in females. Males and females were not found to have significant differences in caries rates. However, statistically significant differences in AMTL were found with females exhibiting more tooth loss than males ( p=.022). When compared across age categories, reproductive-age females had substantial increases in AMTL compared to …
