Track Structure Model Of Cell Damage In Space Flight, Robert Katz, Francis A. Cucinotta, John W. Wilson, Judy L. Shinn, Duc M. Ngo

Robert Katz Publications

Cell damage by high linear energy transfer (LET) radiations has been described by a phenomenological model (track theory) for more than 20 years. With track theory, molecules of biological significance (dry enzymes and viruses) act as one-hit detectors. Recent additions to tire class of one-hit detectors arc Escherichia coil B, and single- and double-strand breaks in SV-40 virus in EO buffer, where indirect effects predominate. The response of cells (survival, transformation, and chromosome aberration) to these radiations is typically described by a four-parameter model whose numerical values are determined from the equations of the theory being fit to experimental …

Altered Expression Of Adenovirus 12 Dna-Binding Protein But Not Dna Polymerase During Abortive Infection Of Hamster Cells, Lynne A. Lucher, Benjawan Khuntirat, Jiansheng Zhao, Peter C. Angeletti

Nebraska Center for Virology: Faculty Publications

Replication of human adenovirus type 12 DNA is blocked in abortively infected baby hamster kidney cells. The activity and accumulation of adenovirus 12 DNA polymerase is equivalent in infected hamster and human cell extracts. However, the accumulation of adenovirus type 12 DNA-binding protein is approximately 120-fold lower in extracts from infected hamster cells when compared to infected permissive human cells. This difference in accumulation is not because of replication of viral DNA during productive infection, since this difference is observed in the presence of hydroxyurea. The DNA-binding protein from infected hamster cells retains the ability to bind denatured DNA-cellulose. An …

Validity Of The Distinction Between Generalized Social Phobia And Avoidant Personality Disorder, James D. Herbert, Debra A. Hope, Alan S. Bellack

Department of Psychology: Faculty Publications

Disorders of pervasive social anxiety and inhibition are divided into 2 categories, generalized social phobia (GSP) and avoidant personality disorder (APD). We explored the discriminative validity of this categorization by examining the comorbidity of GSP and APD and by comparing these groups on anxiety level, social skills, dysfunctional cognitions, impairment in functioning, and presence of concurrent disorders. Results from 23 subjects showed high comorbidity of the 2 diagnoses: All subjects who met criteria for APD also met criteria for GSP. APD was associated with greater social anxiety, impairment in functioning, and comorbidity with other psychopathology, but no differences in social …

Coprolite Analysis: A Biological Perspective On Archaeology, Karl J. Reinhard, Baughn M. Bryant Jr

Karl Reinhard Publications

The most remarkable dietary remains recoverable from archaeological contexts are coprolites. Coprolites are desiccated or mineralized feces that are preserved in sheltered and open sites in arid regions, primarily in the New World. These dietary remains are remarkable from several perspectives. They typically contain a variety of macroscopic and microscopic remains that form interrelated data sets for the reconstruction of diets. Because contexts containing coprolites are typified by excellent preservation, the remains coprolites contain tend to be in better states of preservation than dietary remains recovered from nonfecal deposits. Coprolites also contain the well-preserved remains of intestinal parasites and pathogens …

Dan Canyon Burial: A Piii Burial In Glen Canyon National Recreation Area, Steve Dominguez, Karl Reinhard, Kari L. Sandness, Cherie A. Edwards, Dennis Danielson, F. A. Calabrese, Chris Kincaid

Karl Reinhard Publications

The Dan Canyon burial was discovered at a time when the philosophy, ethics, and legislation concerning the study of human remains are in a state of flux. A number of important sensitive issues germane to managers, archeologists, and American Indians are discussed in the introduction. The subsequent analysis provides a detailed scientific account of these remains and a glimpse of a segment of a people's past lifeway while remaining sensitive to the wishes of the American Indians.

The burial and associated grave goods of site 42SA21339 were exposed by wave action in a location frequented by boaters at the Glen …

Consultant And Client Outcomes Of Competency-Based Behavioral Consultation Training, Susan M. Sheridan

Department of Educational Psychology: Faculty Publications

This article examines how despite increasing demands and empirical support for consultation, its actual practice in schools continues to be limited. One barrier to the systematic provision of consultation services in the schools may be the lack of applied training provided to preservice individuals in graduate preparation programs. A model of behavioral consultation training which extends previous competency- based programs is presented. Trained five doctoral students in school psychology in behavioral consultation procedures using written manuals, videotape models, behavioral rehearsal, performance feedback, self-monitoring, and generalization training. Following university-based practice with trained consultees and student teachers, consultants were assigned consultation cases …

Categorizing Professional Discourse: Engineering, Administrative, And Technical/Professional Writing, Barbara Couture

Department of English: Faculty Publications

Rhetorical categories can and should be developed by scholars of professional writing to identify how values held within professions constrain the ways discourse is interpreted in organizational settings. Empirical research (conducted by the author and others), discourse theory, and pedagogical practice in professional writing strongly suggest that at least three categories of professional writing exist: engineering, administrative, and technical/professional writing. The author demonstrates this claim and distinguishes the characteristics of these three categories. Engineering writing is shown to respond to professional values of scientific objectivity and professional judgment as well as to corporate interests. Administrative writing reflects the locus of …

Analysis Of The Backbone Dynamics Of The Ribonuclease H Domain Of The Human Immunodeficiency Virus Reverse Transcriptase Using 15N Relaxation Measurements, Robert Powers, G. Marius Clore, Stephen J. Stahl, Paul T. Wingfield, Angela Gronenborn

Robert Powers Publications

The backbone dynamics of the uniformly ¹⁵N-labeled ribonuclease H (RNase H) domain of human immunodeficiency virus (HIV- 1) reverse transcriptase have been investigated using two-dimensional inverse-detected heteronuclear ¹⁵N-^lH NMR spectroscopy. ¹⁵N T₁, T₂, and nuclear Overhauser enhancement (NOE) data were obtained for 107 out of a total of 134 backbone amide groups. The overall rotational correlation time (T_R) for the protein at 26˚ is 10.4 ns. The backbone N-H vectors for all the measurableresidues exhibit very fast motions on a time scale of <20 ps. The ¹⁵N relaxation data for …

Determination Of The Secondary Structure And Folding Topology Of Human Interleukin-4 Using Three-Dimensional Heteronuclear Magnetic Resonance Spectroscopy, Daniel S. Garrett, Robert Powers, Carl J. March, Eric A. Frieden, G. Marius Clore, Angela M. Gronenborn

Robert Powers Publications

The secondary structure of human recombinant interleukin-4 (IL-4) has been investigated by three-dimensional (3D) ¹⁵N- and ¹³C-edited nuclear Overhauser (NOE) spectroscopy on the basis of the ¹H, ¹⁵N, and ¹³C assignments presented in the preceding paper [Powers, R., Garrett, D. S., March, C. J., Frieden, E. A,, Gronenborn, A. M., & Clore, G. M. (1992) Biochemistry (preceding paper in this issue)]. Based on the NOE data involving the NH, C^αH, and C^βH protons, as well as ³J_HNα coupling constant, amide exchange, and ¹³C^α and ¹³C^{β …}

1H, 15N, 13C, And 13Co Assignments Of Human Interleukin-4 Using Three-Dimensional Double- And Triple-Resonance Heteronuclear Magnetic Resonance Spectroscopy, Robert Powers, Daniel S. Garrett, Carl J. March, Eric A. Frieden, Angela M. Gronenborn, G. Marius Clore

Robert Powers Publications

The assignment of the ¹H, ¹⁵N, ¹³CO, and ¹³C resonances of recombinant human interleukin-4 (IL-4), a protein of 133 residues and molecular mass of 15.4 kDa, is presented based on a series of 11 three-dimensional (3D) double- and triple resonance heteronuclear NMR experiments. These studies employ uniformly labeled ¹⁵N- and ¹⁵N/¹³C-labeled IL-4 with an isotope incorporation of >95% for the protein expressed in yeast. Five independent sequential connectivity pathways via one-, two-, and three-bond heteronuclear J couplings are exploited to obtain unambiguous sequential assignments. Specifically, CO(i)-N(i+l),NH(i+l) correlations are observed in the HNCO …

Matching Cattle Nutrient Requirements To A Ranch’S Forage Resource, Or “Why We Calve Late”, Gregg Simonds

Range Beef Cow Symposium

Our goal at Deseret Land and Livestock is to maximize long-term profit. Our profit is a function of the following factors: the prices we receive for our production, our amount of production, the costs of production, and the productive capabilities of our land and labor. Prices, production, and cost are managed on an annual basis. The long-term outcome of one’s management is determined by their attention and skill in enhancing the capability of land and labor.

These factors of profit can vary tremendously within and between years. For example, prices for 400-500 pound steer calves from 1979-1989 varied nearly $.58/pound …

Retained Ownership Revisited: Balancing Market Prices And Genetic Potential, John J. Wagner, Dillon M. Feuz

Range Beef Cow Symposium

Retained ownership is a marketing strategy that involves maintaining ownership of young cattle beyond calf weaning, a traditional marketing time for many producers. Numerous retained ownership strategies exist. It is extremely important for producers and their lenders to clearly understand the advantages and disadvantages of a specific retained ownership strategy in order to fully evaluate profit potential.

The advantages and disadvantages of retained ownership have been discussed by several authors. Advantages include 1) compensation for superior genetics, 2) reduction in market inefficiencies, 3) increased quality control in beef, 4) reduction in market risk for frost or drought damaged crops and …

Evaluation And Practical Use Of Research Results For Developing Grazing Strategies, Patrick Reese

Range Beef Cow Symposium

Given the diversity of potential objectives and production environments there are many types of research beyond grazing studies that can be used to design grazing strategies. Management perception and awareness of information are important factors in the development of creative and efficient grazing strategies. Well thought out and clearly documented goals and objectives will help to identify the kind of information that is needed. Grazing strategies should be financially and ecologically sound in respect to management objectives, but most importantly, they should be as simple and risk free as possible. The relative value of any information must be based upon …

How Do Resources Influence Time Of Calving: “Why We Calve Early”, John N. Price

Range Beef Cow Symposium

When I was asked to give this presentation on “WHY WE CALVE EARLY” I said this is easy “because it works for us.” Now that I sit down and think about why it works I find myself going over five generations of inspirations, frustrations, work, sleepless nights, and determination to understand why “IT WORKS FOR US”.

The Price Ranch is a family operation that has been in the family for five generations. The present day Prices consist of my father Richard Price, stepmother Lylamae, wife and best friend Pam, three children John R., Shannon and Angela and two excellent full …

Management Of High Nitrate Forages, Doug L. Hixon

Range Beef Cow Symposium

Each year various regions of western range country are affected by weather and other environmental conditions that stress growing plants, causing them to accumulate nitrates. Of 183 forage samples analyzed for nitrates at the Wyoming State Chemical Lab from July 1 to December 31, 1989, 27% had potassium nitrate levels of 1.5% or greater. At these levels, when ingested by livestock and particularly cattle, the possibility of nitrate toxicoses are highly probable. In this paper, an attempt will be made to review the literature in order to give the producer a better understanding of potential problems and precautions necessary to …

If Immunity Fails, Don’T Pick On Your Drug Salesman – It May Be Nutritional, Cheryl F. Nockels

Range Beef Cow Symposium

“But I vaccinated those calves for enterotoxemia, they couldn’t have died from Clostridium perfringens. That vaccine must not be any good! Just wait until I get hold of that drug company salesperson.” Does this scenario or a similar experience seem familiar to you? I’m not saying that there aren’t times when vaccines fail to cause the animal to produce its own protective response by stimulating the immune system. A substance foreign to the body that induces the immune system to response is called an antigen, as found in vaccines or organisms such as bacteria or viruses. An animal’s immunological …

Are Your Range Cattle Wormy: Does It Make “Cents” To De-Worm?, William R. Jolley

Range Beef Cow Symposium

Range cattle provide room and board for a large variety of flatworm and roundworm parasites. A parasite is by definition an agent that inflicts a degree of harm to a host, and the damage caused depends on the innate abilities, size of the population, duration of infection and other factors tied to the parasite. Host-related factors are also important, including breed, age, sex and condition. The damage to animals may be obvious, with clinical signs including diarrhea, loss of weight, “bottle jaw” (swelling under the jaw), rough hair coat, reproductive/breeding dysfunction and, in severe cases, feed waste due to an …

Early Death Loss In Calves From Diarrhea, John U. Thomson

Range Beef Cow Symposium

Death loss in the calf crop is associated with the cost of the calf, labor, lost cow production, and stress on the ranch or farm management. One should be aware that the cause of death in most diarrheic calves is metabolic acidosis and/or dehydration (1). Many calves will survive the common pathogens causing diarrhea when proper supportive therapy is provided. The diarrheic calf can be treated without knowledge of the specific etiological agent, however, a definitive diagnosis can assist in the development of helpful prevention and management practices (2). Identifying the causative agent can be helpful in selection of the …

Instrumental Valuation Indicators For Natural Resources And Ecosystems, F. Gregory Hayden

Department of Economics: Faculty Publications

Beldon Daniels, in the early draft of his latest book, which has a working title of Rediscovering America, 1992, has written that there have been four major eras in human history. The fourth, into which we are now evolving, according to Daniels, is the age of intelligence. Although the intelligence activity of the modern age both uses and directs the development of large quantities of data, information, and knowledge; a measurement concept, or unit for valuation has yet to be developed. The industrial age from which we are evolving, consistent with the technology of that era, has used industrial …

States Of Mind Model And Cognitive Change In Treated Social Phobics, Monroe A. Bruch, Richard G. Heimberg, Debra A. Hope

Department of Psychology: Faculty Publications

The applicability of Schwartz and Garamoni’s (1986, 1989) States of Mind (SOM) model for assessing the influence of cognitive-behavioral therapy on cognitive functioning was evaluated with social phobics. The SOM model states that a positive dialogue (i.e., a 2:1 ratio of positive to negative thoughts) is optimal for effective coping. Social phobics receiving either a cognitive-behavioral or educational-supportive group treatment were compared for SOM change, as were subjects meeting criteria for improvement or nonimprovement. Also the study compared the predictability of the SOM ratio with a ratio based on percent of negative thoughts. Subjects in both treatments evidenced negative monologue …

A Novel Transposon Trap For Mycobacteria: Isolation And Characterization Of Is1096, Jeffrey D. Cirillo, Raul G. Barletta, Barry R. Bloom, William R. Jacobs Jr.

School of Veterinary and Biomedical Sciences: Faculty Publications

In the course of developing strategies to obtain a mutation in the aspartate semialdehyde dehydrogenase (asd) gene of Mycobacterium smegmatis, an efficient transposon trap was constructed which may be generally useful for the identification of transposable elements in mycobacteria. A DNA fragment containing the asd gene was replaced with an aminoglycoside phosphotransferase gene (aph) to generate a Δasd::aph allele. Attempts to replace the wild-type asd gene with the Δasd::aph allele were unsuccessful, suggesting that this deletion was lethal to the growth of M. smegmatis. The plasmid, pYUB215, which …

Validity Of Intelligence Test Scores In The Definition Of Learning Disability: A Critical Analysis, D. J. Francis, K. A. Espy, B. P. Rourke, J. M. Fletcher

Developmental Cognitive Neuroscience Laboratory: Faculty Publications

The relationship of intelligence test performance to learning deficiency is a longstanding issue affecting treatment and research on learning disabled children. Despite many questions concerning the use of intelligence tests for classifying disabled learners, these tests have become entrenched in every form of work with these children (Kaufman, 1979; Sattler, 1988).
