Sex Reversal Of Tilapia In Earthen Ponds, Tom Popma, Bartholomew Green

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

This Aquacultural Production Manual from the International Center for Aquaculture at Auburn University is oriented towards field application rather than rigorous scientific evaluation of the described techniques. The management practices have been field tested and proven feasible at the described scale of production.

The intended readers are intermediate to upper level technicians with experience in related aquacultural activities. As such, a basic understanding of the principles of aquatic production and of the life history and environmental requirements of tilapia is presumed.

Pesticide Use On Crops In Nebraska - 1987, Maurice Baker, Nancy Peterson, Shripat T. Kamble

Nebraska Agricultural Experiment Station: Historical Research Bulletins

This is the third and most comprehensive study of pesticide use on crops in Nebraska. The first was completed in 1978 and the second one in 1982. The first study indicated that approximately 25 million pounds (11.34 million kg) of active ingredients were used on the major crops in Nebraska. This increased to approximately 30.2 million pounds (13.7 million kg) in 1982. The USDA requires accurate information to meet their responsibilities. Thus, this survey was undertaken to determine: 1) the use of pesticides on crops, pasture and rangeland and 2) to identify pest management practices.

Nebraska Farm Real Estate Market Developments 1989-90, Bruce B. Johnson, Timothy Schroeder

Nebraska Farm Real Estate Reports

In Nebraska, 1989 was another year of active market activity and increasing agricultural land values. These were two of the findings evident from the 1990 Nebraska Farm Real Estate Market Survey reports. The 1990 survey revealed a smaller average rate of increase of 9 percent during the 12-month period ending February 1, 1990 than reported for the year earlier. This smaller increase is a reflection of previous increases in farmland values and some decrease in net farm income during 1989.

The crop reporting districts showing the highest average land value change for the 12-month period were the North and Central …

Nebraska Adolescents' Hiv/Aids Attitudes, Knowledge And Related Practices: 1989, Ian Newman, Joe Lutjeharms, Joanne Owens-Nauslar, Autumn Koch

Department of Educational Psychology: Faculty Publications

This Prevention Center Paper (No. 22) describes the HIV/AIDS related knowledge, attitudes and practices of a random sample of 1240 Nebraska adolescents in grades 9-12. The data were gathered in 1989.
Data were gathered by staff of Health Education, Inc., a Nebraska-based nonprofit research and development corporation, as part of a contract with the Nebraska Department of Education. The Nebraska Department of Education has a major HIV /AIDS cooperative agreement with the U.S. Centers for Disease Control (CDC) in Atlanta, Georgia.
Schools were selected at random from each of the six classifications of Nebraska schools established by the Nebraska Department …

Heterogeneous Within-Herd Variance. 2. Genetic Relationships Between Milk Yield And Calving Interval In Grade Holstein Cows, T. H. Short, R. W. Blake, R. L. Quaas, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Genetic and phenotypic (co)variances for mature equivalent yield of 4% FCM and calving interval were simultaneously estimated by REML for grade Holstein cows in first and second parity. Data were 305d mature equivalent lactation records and calving dates for 299,441 daughters of 2489 AI sires first calving from 1970 to 1985 in California, New York, or Texas. Data were divided into three time periods, and herds were partitioned into three within-herd-year phenotypic SD classifications for milk yield. Average FCM yield and calving interval increased with SD in all time periods for both parities. Genetic variance of calving interval showed no …

Conservation Genetics Of Pacific Salmon, Robin Waples, David Teel

United States Department of Commerce: Staff Publications

Recent reductions in the abundance of all Pacific salmon species (Oncorhynchus spp.), coupled with large in- creases in artificial production, demand that careful attention be paid to genetic changes occurring in both wild and cultured populations. Analysis of electrophoretic data for chinook salmon (O. tshawytscha) from the Pacific coast of Oregon revealed substantial allele frequency changes over 2-4 years in hatchery, but not wild, populations. Unfortunately, our understanding of the causes of this result is hampered by a lack of theoretical models designed for organisms with life history features like those of Pacific salmon. We used computer …

Replication And Amplification Of Defective Interfering Particle Rn As Of Vesicular Stomatitis Virus In Cells Expressing Viral Proteins From Vectors Containing Cloned Cdnas, Asit K. Pattnaik, Gail W. Wertz

School of Veterinary and Biomedical Sciences: Faculty Publications

Replication and amplification of RNA genomes of defective interfering (DI) particles of vesicular stomatitis virus (VSV) depend on the expression of viral proteins and have untD now been attained only in ceUs coinfected with helper VSV. In the work described in this report, we used a recombinant vaccinia virus-T7 RNA polymerase expression system to synthesize individual VSV proteins in cells transfected with plasmid DNAs that contain cDNA copies of the VSV genes downstream of the T7 RNA polymerase promoter. In this way, we were able to examine the ability of VSV proteins, individually and in combination, to support DI particle …

Disappearance And Recoverability Of Songbird Carcasses In Fruit Orchards, Mark E. Tobin, Richard A. Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

Songbird mortality due to agricultural pesticides is often assessed by searching treated areas for carcasses. However, carcass removal by scavengers and the failure of searchers to find carcasses that are present may bias mortality estimates. We conducted two studies in 1987 and 1988 in New York to evaluate such biases at the time of fruit maturation in cherry and apple orchards. In the first study, mean survival times for carcasses were 8.2 d in cherry and 10.4 d in apple orchards. In the second study, searchers located an average of 75% of carcasses placed in orchards. Our results suggest that …

A Comparison Of Smoking Cessation Methods In Normal Smokers And Smokers With Chronic Obstructive Pulmonary Disease, Mary Beth Mueller

Open Access Master's Theses (through 2010)

This research was designed to investigate whether there would be a difference in mean exhaled carbon monoxide levels and mean number of cigarettes smoked for two randomized groups of smokers.Smoking cessation therapy was manipulated in smokers with a chronic, productive cough (COPD) and those who were asymptomatic (normal). Individual therapy was compared to self-help therapy.The main purpose of this study was an attempt to define the smoking cessation therapy that worked best for each of these two groups.With the information gained from this research, it was hoped that educating different types of smokers (those with and without lung disease) about …
