Isolation Of Galactose-Fermenting Thermophilic Cultures And Their Use In The Manufacture Of Low Browning Mozzarella Cheese, Kamla K. Mukhurjee, Robert W. Hutkins

Department of Food Science and Technology: Faculty Publications

The objectives of this study were to isolate galactose-fermenting, galactosenonreleasing strains of Streptococcus and Lactobacillus and to use these strains as starter cultures in the manufacture of low browning Mozzarella cheese. Four Streptococcus isolates having the desirable phenotype, combined with a Lactobacillus helveticus strain, were acceptable as starter cultures based on activity tests. Fifteen vats of Mozzarella cheese were produced, in triplicate, representing four experimental treatments (made with galactose-nonreleasing strains) and one control (made with a galactosefermenting, galactose-releasing Streptococcus). Analyses were performed on cheese after 5 and 28 d of refrigerated storage. The lactose and galactose content of cheese …

A New Species Of Opatrinus (Coleoptera: Pedinini: Tenebrionidae) From Cuba, Orlando H. Garrido, Esteban Gutierrez

Insecta Mundi

A new species of an endemic tenebrionid beetle, Opatrinus armasi, is described from the environs of San Antonio de los Banos, Havana Province. The new species is found living syntopically in this area with the more widespread 0. pullus. Comparisons with various populations of this latter species are made. Photographs of the beetles, drawing of pronotum, as well as males genitalia of both species are given.

Identification And Characterization Of A Human Herpesvirus 6 Gene Segment Capable Of Transactivating The Human Immunodeficiency Virus Type 1 Long Terminal Repeat In An Spl Binding Site-Dependent Manner, Jinhai Wang, Clinton J. Jones, Michael Norcross, Ernst Bohnlein, Abdur Razzaque

School of Veterinary and Biomedical Sciences: Faculty Publications

The human immunodeficiency virus type 1 (HIV-1) long terminal repeat (LTR) is transactivated by various extracellular signals and viral cofactors that include human herpesviruses. These transactivators are capable of transactivating the HIV-1 LTR through the transactivation response element, NF-KB, or other regulatory binding elements. Human herpesvirus 6 (HHV-6) is a potential cofactor of HIV-1. Here, we report that an HHV-6 gene segment, ZVH14, which can neoplastically transform NIH 3T3 and human keratinocytes, is capable of transactivating HIV-1 LTR chloramphenicol acetyltransferase constructs in an Spl binding site-dependent manner. Transactivation increased synergistically in the presence of multiple Spl sites and was dramatically …

Policy Considerations For Contraception In Wildlife Management, Wendy A. Sanborn, Robert H. Schmidt, Herbert C. Freeman

Vertebrate Pest Conference Proceedings: 16th (1994)

Managing wildlife populations by manipulating their birth rates is a promising technology. However, the use of contraceptive technologies will involve the development of new wildlife management policies. We designed and implemented a survey that was intended to gather information on the range of perspectives of concerned publics on contraceptive use in wildlife management. There appears to be considerable confusion and mistrust regarding the application and appropriateness of this new technology. We recommend that promoters of contraception use in wildlife management be careful to explain what this new technology can and cannot do in order to avoid the pitfalls associated with …

Supplemental Bear Feeding Program In Western Washington, Georg J. Ziegltrum

Vertebrate Pest Conference Proceedings: 16th (1994)

Black bear (Ursus americanus) damage to trees is a severe problem in the Pacific Northwest. Significant damage has been observed for many years, especially in highly managed private industrial forests in western Washington. The introduction of intensive silvicultural techniques resulted in higher yields, but may have also made trees more vulnerable to black bear destruction. Early lethal control efforts lost public support and the forest products industry investigated different methods that concentrated on non-lethal management tools. In 1985, the Washington Forest Protection Association introduced supplemental bear feeding as a damage prevention program in high damage areas during the …

Using Geographic Information Systems For Tracking An Urban Rodent Control Program, Matt Von Wahlde, Bruce A. Colvin

Vertebrate Pest Conference Proceedings: 16th (1994)

Geographic information system technology is being used to help coordinate an urban rodent control program initiated as part of the Central Artery/Tunnel Project in Boston. Databases with neighborhood survey data, surface and subsurface baiting data, sanitation code violations, and public complaints are linked to base mapping, land parcel, and utility graphics. This integrated approach helps Project biologists plan control strategies and evaluate the relatedness of rodent activity to environmental conditions. Spatial querying techniques and the ability to graphically display and map variables, such as bait stations and sanitation deficiencies, help ensure that control resources are effectively targeted and tracked. This …

Registration Requirements For Non-Toxic Natural Products As Animal Damage Control Agents, Stephen A. Schumake

Vertebrate Pest Conference Proceedings: 16th (1994)

Plant extracts, animal glandular secretions and excretions, and natural food flavoring agents are common sources of natural products that can be used in animal damage control applications. Such products can be used either by themselves (e.g., coyote urine as a rodent repellent), or in combination with other control agents (e.g., food odor or flavor enhancer at baiting sites). The Environmental Protection Agency registration requirements are described for a variety of potential applications of natural products including bird and rodent repellents. In some applications, the product chemistry or other data requirements could make the registration process prohibitive due to the cost …

Wolf Depredation Management In Relation To Wolf Recovery, Carter C. Niemeyer, E.E. Bangs, S.H. Fritts, J.A. Fontaine, M.D. Jimenez, W.G. Brewster

Vertebrate Pest Conference Proceedings: 16th (1994)

By 1930, wolves were extirpated from the western United States for livestock protection. In 1973, the Endangered Species Act protected wolves, and by 1980, wolf recolonization began in Montana. Confirmed livestock losses have been 17 cattle and 12 sheep with 16 wolves controlled as part of a program to enhance the recovery of non-offending wolves. ADC has: 1) controlled problem wolves, 2) improved communication with affected publics and governmental agencies, and 3) enhanced wolf recovery in Montana.

What Do Animal Activists Want? (And How Should Wildlife Managers Respond?), Jon K. Hooper Phd.

Vertebrate Pest Conference Proceedings: 16th (1994)

National animal activist organization leaders were interviewed with the aim of better understanding their ideologies with respect to wildlife issues. Interviewees expressed considerable concern about traditional wildlife management practices and associated consumptive recreation activities. They easily identified a number of needed changes, while had difficulty identifying things they liked about the status quo. The top suggested changes related to using more nonlethal management methods and reducing allegiance with consumptive users. The most common "bottom line" concern expressed by interviewees was the alleviation or elimination of unnecessary pain and suffering in wildlife.

Charting A Future: Process And Promise, Bobby R. Acord, Craig A. Ramey, Robert W. Werge

Vertebrate Pest Conference Proceedings: 16th (1994)

The Animal Damage Control program has been heavily involved in strategic planning since its transfer from USDI to USDA. The first effort was undertaken in 1989 by the program's management team. It was an introspective, critical look at what changes were needed to improve the program's strategic position in the natural resources community. That plan failed to achieve the desired objective due principally to the lack of involvement by ADC employees and others outside the program. In 1991, a more comprehensive effort was begun known as "Futuring." In this process, a representative from each organizational level of the program and …

Drought Monitoring And Advisory Services In South Africa, M. V. Laing

Drought Network News (1994–2001)

The normal total rainfall for the summer rainfall areas in South Africa is 664 mm. Since 1963, the country has recorded 16 seasons below normal and 14 above normal. Since the 1982–83 season, 7 seasons have been below normal and 4 have been above normal. Of these last 11 years, two rainy seasons recorded less than 75% of normal rainfall, which is a coarse estimation of severe drought. These seasons were 1982–83, when an average total of only 408 mm was measured, and 1992–93, when the average total was 484 mm. Although 1991–92 has been called the worst drought this …

Inhomogeneous Anisotropic Percolation: Two-Dimensional Numerical Threshold Analysis, Yuris A. Dzenis, S. P. Joshi

Department of Engineering Mechanics: Faculty Publications

Monte Carlo simulations of percolation on a square lattice with anisotropic inhomogeneous probability distribution are reported. Finite-size scaling is used for data analysis. As inhomogeneity increases, the critical probability decreases; whereas the correlation-length exponent remains, within computation errors, the same as in classical two-dimensional percolation.

Who Wants To Stop The Church: Homosexual Rights Legislation, Public Policy, And Religious Freedom, Richard F. Duncan

Nebraska College of Law: Faculty Publications

Religions that make peace with the spirit of the age have little to fear from the rulers of the day. But believers who refuse to adapt their religious practices to the Zeitgeist are vulnerable under Smith, unless the Court decides to protect religious pluralism by giving full scope to Smith's exceptions.

I have tried to show that homosexual rights legislation imposes heavy costs on the right of employers and landlords to take character into account when making business decisions. These costs are particularly heavy when borne by religiously-motivated persons, who are declared outlaws merely for trying to obey God …

Identification And Characterization Of Aspergillus Nidulans Mutants Defective In Cytokinesis, Steven D. Harris, Jennifer L. Morrell, John E. Hamer

Department of Plant Pathology: Faculty Publications

Filamentous fungi undergo cytokinesis by forming crosswalls termed septa. Here, we describe the genetic and physiological controls governing septation in Aspergillus nidulans. Germinating conidia do not form septa until the completion of their third nuclear division. The first septum is invariantly positioned at the basal end of the germ tube. Block-and-release experiments of nuclear division with benomyl or hydroxyurea, and analysis of various nuclear division mutants demonstrated that septum formation is dependent upon the third mitotic division. Block-and-releasee xperiments with cytochalasin A and the localization of actin in germlings by indirect immunofluorescence showed that actin participated in septum formation. In …

Bird Dispersal Techniques, Thurman W. Booth

Prevention and Control of Wildlife Damage Handbook

Birds, especially migratory birds, provide enjoyment and recreation for many and greatly enhance the quality of our lives. These colorful components of natural ecosystems are often studied, viewed, photographed, hunted, and otherwise enjoyed. Unfortunately, bird activities sometimes conflict with human interests. Birds may depredate agricultural crops, create health hazards, and compete for limited resources with other more favorable wildlife species. The management of bird populations or the manipulation of bird habitats to minimize such conflicts is an important aspect of wildlife management. Problems associated with large concentrations of birds can often be reduced through techniques of dispersal or relocation of …

Highly Reactive Forms Of Zinc And Reagents Thereof, Reuben D. Rieke

Department of Chemistry: Faculty Publications

A novel zerovalent zinc species and an organozinc reagent are disclosed. The zerovalent zinc species is directly produced by reaction of a reducing agent on a zinc salt, preferably Zn(CN)₂. The organozinc reagent results from the reaction of the zerovalent zinc species and an organic compound having one or more stable anionic leaving groups. These organozinc reagents include a wide spectrum of functional groups in the organic radical, and are useful in a variety of reactions schemes.

Ec94-805 Existing Business Retention And Expansion Handbook, Duane A. Olsen, Cheryl Burkhart-Kriesel

University of Nebraska-Lincoln Extension: Historical Materials

Since the mid 1980s more than a dozen communities in Nebraska have carried out the Business Retention and Expansion (BRE) program that is outlined in this handbook. Without exception both the communities and the businesses involved have reported positive results. The BRE program is a stuctured, locally implemented, action oriented economic development project aimed at stimulating local economic development ard growth by helping existing business. This handbook is designed as a guide for community leaders planning to carry out a Business Retention and Expansion program. Due to variations in local needs and resources, communities are encouraged to customize these tools.

Adsorption-Dissolution Reactions Affecting The Distribution And Stability Of Coii Edta In Iron Oxide-Coated Sand, James E. Szecsody, John M. Zachara, Patrick Bruckhart

United States Department of Energy: Publications

The time-variant chemical behavior of Co^IIEDTA (and other metal-EDTA complexes) was investigated in suspensions of iron oxide-coated sand to identify equilibrium and kinetic reactions that control the mobility of Me^IIEDTA complexes in subsurface environments. Batch experiments were conducted to evaluate the adsorption as a function of pH, concentration, and time and to quantify the rate-controlling step(s) of dissolution of the iron oxide by EDTA complexes. Ionic Co²⁺ exhibited typical cation-like adsorption, whereas Me^IIEDTA adsorption was ligand-like, increasing with decreasing pH. Adsorption isotherms for all reactive species exhibited Langmuir behavior, with site saturation occurring …

A Novel Protein, Csg2p, Is Required For Ca2+ Regulation In Saccharomyces Cerevisiae, Troy Beeler, Kenneth Gable, Chun Zhao, Teresa Dunn

Uniformed Services University of the Health Sciences

Nineteen mutants that lost the ability to grow in 100 mM Ca²⁺ (but remained insensitive to 50 mM Sr²⁺) were identified in a screen of approximately 60,000 mutagenized yeast colonies. Cells carrying mutations in the CSG2 gene grow normally in low Ca²⁺ medium but have decreased growth rates when the Ca²⁺ concentration is above 10 mM. The csg2 mutant cells accumulate much higher levels of Ca²⁺ in a compartment that is exchangeable with extracellular Ca²⁺ but the nonexchangeable Ca²⁺ pool which predominates in wild-type cells is not influenced. Sr²⁺ influx is …

Regulation Of Cellular Ca2+ By Yeast Vacuoles, Teresa Dunn, Kenneth Gable, Troy Beeler

Uniformed Services University of the Health Sciences

The role of vacuolar Ca²⁺ transport systems in regulating cellular Ca²⁺ was investigated by measuring the vacuolar Ca²⁺ transport rate, the free energy available to drive vacuolar Ca²⁺ transport, the ability of the vacuole to buffer lumenal Ca²⁺, and the vacuolar Ca²⁺ efflux rate. The magnitude of the Ca²⁺ gradient generated by the vacuolar H⁺gradient best supports a 1 Ca²⁺:2 H⁺ coupling ratio for the vacuolar Ca²⁺/H⁺ exchanger. This coupling ratio along with a cytosolic Ca²⁺ concentration of 125 nM would give a …
