Consumption & Attitudes About Whole Grain Foods Of Unl Students Who Dine In A Campus Cafeteria, Kimberly J. Bisanz, Kaye L. Stanek Krogstrand

RURALS: Review of Undergraduate Research in Agricultural and Life Sciences

Strong, research-based evidence indicates the consumption of whole grains lowers the risk of chronic diseases, including type 2 diabetes mellitus, cardiovascular disease, and certain cancers, along with aiding weight regulation. Consequently, the 2005 Dietary Guidelines for Americans set forth by the Department of Health and Human Services (HHS) and the Department of Agriculture (USDA) placed an increased emphasis on whole grains in the American diet. It is recommended that at least one-half of the grains in a daily diet, or approximately 3 one-ounce servings, should be whole grain. The hypothesis of this research was that students eating in campus dining …

The Transcriptional Repressor K-Rbp Modulates Rta-Mediated Transactivation And Lytic Replication Of Kaposi’S Sarcoma-Associated Herpesvirus, Zhilong Yang, Charles Wood

Nebraska Center for Virology: Faculty Publications

The replication and transcription activator (RTA) protein of Kaposi’s sarcoma (KS)-associated herpesvirus (KSHV)/human herpesvirus 8 functions as the key regulator to induce KSHV lytic replication from latency through activation of the lytic cascade of KSHV. Elucidation of the host factors involved in RTA-mediated transcriptional activation is pivotal for understanding the transition between viral latency and lytic replication. KSHV-RTA binding protein (K-RBP) was previously isolated as a cellular RTA binding protein of unknown function. Sequence analysis showed that K-RBP contains a Kruppel-associated box (KRAB) at the N terminus and 12 adjacent zinc finger motifs. In similarity to other KRAB-containing zinc finger …

Early Investment In Soil Conservation Research Continues To Provide Dividends, John E. Gilley, D. C. Flanagan

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Current soil conservation programs are built upon an established research legacy. Hugh H. Bennett, chief of the USDA Soil Conservation Service from 1935 to 1951, was instrumental in the establishment of a network of 35 soil conservation experiment stations (SCES). Research projects were initiated at the SCES in the 1930s to investigate the principal factors causing erosion and to identify the most effective and practical methods of controlling soil loss from agricultural areas. Information obtained from the SCES, and selected other locations, was assembled at the National Runoff and Soil Loss Data Center (NRSLDC) established on the campus of Purdue …

Mountain Beaver: A Primitive Fossorial Rodent, Wendy M. Arjo

United States Department of Agriculture Wildlife Services: Staff Publications

As the largest mammalian order, rodents are nearly cosmopolitan in distribution, can exploit a broad spectrum of foods, and can often reach high population densities. One sole representative of the most primitive family of rodents, Aplodontidae, does not share some of these common rodent characteristics. The aplodontoid rodents in the family Aplodontidae and Mylagsulidae radiated during the Miocene from the Allomyinae family (Carraway and Verts 1993). The extinct Mylagaulidae represents the earlier radiation of these rodents who exhibited great specialization (Carraway and Verts 1993). Unlike the other members of the rodent order, mountain beavers are not prolific breeders; nor are …

Characteristics Of Manure Harvested From Beef Cattle Feedlots, William F. Kissinger, Richard K. Koelsch, Galen E. Erickson, Terry J. Klopfenstein

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Open lot cattle production systems present unique challenges for nutrient planning processes. Previous estimates of quantities and characteristics of harvested manure from this type of facility are based upon data from the early 1970s. In addition, harvested manure is impacted by weather, feeding program, season, and pen management decisions. The objectives of this study are to characterize under commercial conditions for open lot beef systems: 1) harvested manure quantities and characteristics; 2) impact of factors such as feeding program, season, and management on harvested manure; and 3) mass balance for nitrogen (N) and phosphorus (P). Data from six commercial feedlots …

[Re]Considering The Refugee Camp, Matthew C. Stoub

Architecture Masters of Science Program: Theses

Abstract:

Conflict and disaster occurs throughout the world every day. The aftershock of these situations gives rise to millions of stateless persons: refugees. Today, the Camp is virtually synonymous with refugee situations. These institutional establishments are intended as a transitory center for sustaining life until the inhabitants can safely Return home. The tangible reality of these situations is that they become permanent fixtures in the landscape. The current system of warehousing refugees in overpopulated wastelands creates a strong dependence for the victim upon humanitarian aid. The camp is seen as unwanted, parasitic, and as a necessary evil.

Effects Of Forage Management On Pasture Productivity And Phosphorus Content, M. M. Haan, J. R. Russell, J. L. Kovar, W. J. Powers, J. L. Benning

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

The objectives of the current study were to determine the amounts of above- and below-ground plant biomass production, P uptake by forage, and P concentration of cool-season grass forage as influenced by management and season. Five forage management treatments were evaluated over 3 years in smooth bromegrass (Bromus inermis Leyss) pastures. Management practices were: ungrazed (U), hay harvest/fall stockpile grazing (HS), rotational stocking to residual sward heights of 10 (10R) or 5 (5R) cm, and continuous stocking to maintain sward height at 5 cm (5C). Forage samples were hand-clipped within and outside grazing exclosures monthly from April through November …

Dry Bean Intake Of Women Ages 19-45, Julie Eihusen, Julie A. Albrecht

RURALS: Review of Undergraduate Research in Agricultural and Life Sciences

Dry beans are considered an excellent source of folate. A mail-out survey was conducted to measure the dry bean intake of women between the ages of 19 and 45 years and to estimate the amount of folate from beans in the diet. One hundred and seventy-six women reported on the frequency with which they consume foods made with dry beans and the types of dry beans they have previously consumed. The average number of servings of food made with beans per month was 18.5, and the most commonly eaten food made with dry beans was refried beans, averaging 2 times …

Inhibition Of Mold Growth By Sourdough Bread Cultures, Pei Ven Kam, Andreia Bianchini, Lloyd B. Bullerman

RURALS: Review of Undergraduate Research in Agricultural and Life Sciences

Sourdough bread cultures are mixtures of wild yeasts and Lactobacillus bacteria living in flour and water, where they form an interesting symbiosis that makes the culture quite stable. The presence of lactic acid bacteria (LAB) in sourdough bread cultures increases the shelf life of the sourdough bread and other sweet baked goods made with these cultures, due to the inhibitory effect of organic acids on spoilage molds. In addition, it has been found that when sourdough LAB are cultivated they produce antifungal substances, such as organic acids (in particular, lactic acid and acetic acid), carbon dioxide, ethanol, and hydrogen peroxide, …

Effects Of Consumer Perceptions On The Marketing Of Second Generation Genetically Modified Products, Anneke Gustafson, Amalia Yiannaka

RURALS: Review of Undergraduate Research in Agricultural and Life Sciences

The paper examines how the market/consumer acceptance of a second generation, consumer oriented, genetically modified product (new GMP) affects a company’s marketing strategy and its decision to invest in the research and development (R&D) of the new product. Two relationships between the products available in the market and their effect on the monopolist’s marketing strategy are considered, namely, vertical and horizontal product differentiation. Analytical results show that when the new GMP in a vertically differentiated market is viewed as the low quality product it has to be priced lower than the conventional product to capture a positive market share while …

Cholesterol-Lowering Properties Of Plant Sterols Esterified With Beef Tallow Fatty Acids In Hamsters, David M. Guderian Jr., Heather E. Rasmussen, Curtis A. Wray, Patrick Dussault, Timothy P. Carr

Department of Nutrition and Health Sciences: Faculty Publications

Plant sterol esters (PSE) reduce plasma low-density lipoprotein cholesterol concentration by inhibiting cholesterol absorption. Previous work in our laboratory indicated that PSE containing stearic acid (SA), compared to linoleic acid, were significantly more effective at reducing cholesterol absorption. We tested the cholesterol lowering properties of PSE containing fatty acids from beef tallow, a natural and abundant source of SA. Male hamsters were fed diets containing 0.0%, 0.5%, 1.0%, or 5.0% beef tallow PSE for 4 weeks. Dose-dependent reductions (P < .05) were observed in cholesterol absorption, liver esterified cholesterol, and plasma nonhigh-density lipoprotein cholesterol concentration; hamsters fed 5.0% PSE exhibited reductions of 56%, 98%, and 38%, respectively, compared to controls. Concurrent increases (P < .05) in fecal sterol excretion were also observed. In a second hamster study, the cholesterol-lowering properties of beef tallow PSE were compared to hamsters fed molar equivalents of free plant sterols (PS) and free SA. Beef tallow PSE were significantly more effective at reducing liver and plasma cholesterol concentrations than PS and SA consumed individually. Whether PS and SA act through independent or synergistic mechanisms will require further research, although the present findings support the use of dietary PSE containing beef tallow fatty acids in the management of hypercholesterolemia.

Pest Risk Assessment For Feral Pigs In Oregon, Bruce Coblentz, Cassie Bouska

Other Publications in Wildlife Management

Feral pigs, wild boars, and hybrids either currently inhabit, or have been successfully introduced to every continent except Antarctica, and many oceanic islands. There are thirteen current known localities of feral pigs in Oregon (see Appendix A), distributed in various locations in southern and central Oregon. The biology of feral pigs indicates that these animals are capable of inhabiting virtually all available habitat west of the Cascade mountains, and the majority of the habitat east of the Cascades, with preference for riparian regions. Reports of feral pig biology and ecology in other regions in the United States, as well as …

The Kugeria Women Water Project: A Mixed-Methods Evalutation Of A Women’S Micro-Initiative Project, Malinda Nanetté Hill-Schmidtke

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Advisor: John DeFrain

The Kugeria Women Group (KWG) of Murinduko, Kenya, founded in 1989, built an 11- kilometer water pipeline to provide potable water. Almost 20 years later, the pipeline is still providing water to over 300 families and is considered an example of a successful women’s micro-initiative. The two major goals of this dissertation were: 1) to investigate the organizational structures to determine which elements aided KWG in its successfully maintaining a water pipeline, and 2) to analyze KWG’s water consumption to ascertain if KWG stayed within its own pre-described regulations.

Result Mapping found the KWG’s success is an …

Increased Abundance Of Arbuscular Mycorrhizal Fungi In Soil Coincides With The Reproductive Stages Of Maize, M. Susana Grigera, Rhae A. Drijber, Brian J. Wienhold

Department of Agronomy and Horticulture: Faculty Publications

Arbuscular mycorrhizal (AM) fungi are recognized for their positive effects on plant growth, playing an important role in plant P nutrition. We used C16:1cis11 and C18:1cis11 fatty acid methyl ester (FAME) biomarkers to monitor the dynamics of AM fungi during the reproductive stages of maize (Zea mays L.) grown at high yield in Nebraska, USA. Two fields with four different levels of P availability were sampled throughout the reproductive stages. Chambers, made of PVC enclosed mesh fabric to allow passage of roots and hyphae(+R) or hyphae alone (-R) and amended with either KH₂PO …

Adaptation And Mitigation Strategies In Agriculture: An Analysis Of Potential Synergies, Cynthia Rosenzweig, Francesco Nicola Tubiello

United States National Aeronautics and Space Administration: Publications

As climate changes due to rising concentrations of greenhouse gases in the atmosphere, agriculture will be one of the key human activities affected. Projections show that while overall global food production in the coming decades may keep pace with the food requirements of a growing world population, climate change might worsen existing regional disparities because it will reduce crop yields mostly in lands located at lower latitudes where many developing countries are situated. Strategies to enhance local adaptation capacity are therefore needed to minimize climatic impacts and to maintain regional stability of food production. At the same time, agriculture as …

Interleukin-6 And Tumor Necrosis Factor-Alpha Values In Elk Neonates, Shannon M. Barber-Meyer, Craig R. Johnson, Michael P. Murtaugh, L. David Mech, P.J. White

United States Department of Agriculture Wildlife Services: Staff Publications

Serological indicators of general condition would be helpful for monitoring or assessing ungulate wildlife. Toward that end, we report the 1st reference values for 2 cytokines, interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-a), in neonatal elk (Cervus elaphus). We obtained blood samples from 140 calves ≤ 6 days old in Yellowstone National Park during summer 2003–2005. IL-6 values ranged from 0 to 1.21 pg/ml with a median of 0.03 pg/ml. TNF-a values ranged from 0 to 225.43 pg/ml with a median of 1.85 pg/ml. IL-6 and TNF-a concentrations were not significant predictors of elk calf survival through 21 …

An Algorithm For Corn Nitrogen Recommendations Using A Chlorophyll Meter Based Sufficiency Index, Gary E. Varvel, Wally Wilhelm, J. F. Shanahan, James S. Schepers

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

Nitrogen fertilizer continues to be the major input influencing corn (Zea mays L.) yield in the Midwest. Improved N recommendations should result in greater N use efficiency and producer profit while reducing surface and groundwater contamination. This study was conducted to develop a plant-based technique to detect and correct N deficiencies during the season. Chlorophyll meter readings and grain yield were collected from corn in irrigated monoculture corn and soybean [Glycine max (L.) Merr.]–corn cropping systems with four hybrids and five N fertilizer application rates in the Platte Valley near Shelton, NE. Normalized chlorophyll meter readings (sufficiency index, …

Sorghum: A Substitute For Maize In The West Africa Poultry Industry, Intsormil

INTSORMIL Impacts and Bulletins

With the declining relative prices of chicken compared with other meats, poultry consumption per capita in the USA has been increasing, while that of other meats has been stagnant or declining. Similar developments are occurring in West Africa.

There is interest in substituting sorghum for maize in poultry rations, in the U.S. and in West Africa, for both broiler and egg production. In contrast to maize, which is a thirsty plant and requires large amounts of water, sorghum offers farmers the ability to grow a crop where other crops do not produce well. In Niger, West Africa, locally produced sorghum …

Novel Metabolism In Chlamydomonas Through The Lens Of Genomics, Arthur R. Grossman, Martin Croft, Vadim N. Gladyshev, Sebeeha S. Merchant, Matthew C. Posewitz, Simon Prochnik, Martin H. Spalding

Vadim Gladyshev Publications

Chlamydomonas has traditionally been exploited as an organism that is associated with sophisticated physiological, genetic and molecular analyses, all of which have been used to elucidate several biological processes, especially photosynthesis and flagella function and assembly. Recently, the genomics of Chlamydomonas has been combined with other technologies to unveil new aspects of metabolism, including inorganic carbon utilization, anaerobic fermentation, the suite and functions of selenoproteins, and the regulation of vitamin biosynthesis. These initial fi ndings represent the first glimpse through a genomic window onto the highly complex metabolisms that characterize a unicellular, photosynthetic eukaryote that has maintained both plant-like and …
