The Future Of The Great Plains Re-Visited, Gilbert F. White
The Future Of The Great Plains Re-Visited, Gilbert F. White
Great Plains Quarterly (through 2013)
The Future of the Great Plains came in the mid- 1930s at the culmination of a great drought and a festering worldwide economic depression as new, ambitious Washington agencies sought to redress the accumulated wounds to people and soil. Following a series of more narrow reports, this comprehensive study presented the prevailing judgments as to what had gone wrong on the Great Plains. And it outlined a widely shared vision of what the future might hold if its social prescriptions were heeded. 1 Sceptics of the time wryly remarked that the animal on its front cover (a large bull, fig. …
Abideth Forever? Global Use Of Semiarid Lands In The Interwar Years, J. M. Powell
Abideth Forever? Global Use Of Semiarid Lands In The Interwar Years, J. M. Powell
Great Plains Quarterly (through 2013)
I have undertaken a highly selective Cook's Tour in this article, attempting to integrate our understanding of semiarid lands around the globe. The focus is concentrated on the period between the two great wars when new nationalisms, old imperial networks, and the burgeoning ambitions of scientists combined to create new systems of land use in the semiarid regions, but a few sorties have been made into earlier and later periods to assist the interpretation of specific projects. My own country, Australia, is used as the starting point for the tour, but the influence of American Donald Worster's Dust Bowl (1979) …
Inheritance Of Dhurrin Content In Mature Sorghum Leaves, Herman J. Gorz, Francis A. Haskins, K. P. Vogel
Inheritance Of Dhurrin Content In Mature Sorghum Leaves, Herman J. Gorz, Francis A. Haskins, K. P. Vogel
Department of Agronomy and Horticulture: Faculty Publications
Seedlings of both KS8 and N32 sorghum [Sorghum bicolor (L.) Moench] were high in dhurrin [p-hydroxy-(S)-mandelonitrile-β-D-glucoside] and thus in hydrocyanic acid potential (HCN-p), but the HCN-p of mature leaves from field-grown plants of KS8 was only about one-tenth as high as that of N32. A study of the inheritance of this large difference between KS8 and N32 revealed that a single major gene pair was responsible. There were no obvious maternal effects and F,'s were generally intermediate in HCN-p level between the two parents, indicating that neither high nor low HCN-p was completely dominant. HCN-p …

Nebraska Center for Virology: Faculty Publications
We investigated the relationship of the presence of antibodies to HTLV-III and immunologic abnormalities in patients with hemophilia. Serum antibodies to HTLV-III were analyzed by ELISA assay, immunoprecipitation of labeled cell extracts, and immunoprecipitation of purified HTLV-III p24. Thirty-four (61%) of the total group (n = 56) had antibody to HTLV-III; 34 (76%) of 45 patients given commercial factor VIII preparations were seropositive, compared with none of 11 patients treated exclusively with cryoprecipitate obtained from volunteer blood donors. Of patients who were seropositive for HTLV-III antibody, 94% had abnormal T4/T8 ratios, and 33% of those whose serum was antibody …

The Effects Of Rate Of Change In Body Weight On Tissue Development And Meat Quality Of Youthful Bulls, J. D. Crouse, Chris R. Calkins, S. C. Seideman
Department of Animal Science: Faculty Publications
Forty-eight Angus bulls about 13 mo of age were used to study the effects of rate of change in live weight on muscle fiber, collagen and sensory characteristics of meat. Bulls were fed a finishing diet before treatment, and assigned to three treatments: 1) negative, 2) zero or 3) positive weight gain for 30 or 60 d prior to slaughter. Treatments were imposed by adjusting feed intake. Seventy-two hours after slaughter, carcasses were observed for quality and yield grade characteristics and longissimus muscle samples were obtained for fiber type, collagen and sensory characterization. Carcass lean at the 12th rib interface …

G86-789 Human Lice And Their Control, Shripat T. Kamble, David L. Keith, Wayne L. Kramer
University of Nebraska-Lincoln Extension: Historical Materials
This NebGuide includes information on biology and control of three species of lice that infest humans.
Pediculosis (lice infestation) in humans has been known since ancient times. Three types of lice that infest humans: 1) head lice, 2) body lice, and 3) crab or pubic lice.
Lice are small, flat, dirty white to grayish black, wingless insects. Their legs are short and stout, with a large claw on each leg for grasping and holding onto hair. Lice have piercing and sucking mouth parts. These insects are blood feeders and require close contact with human hosts.

Illustrated Guide To Integrated Pest Management In Rice In Tropical Asia, W. H. Reissig, Elvis A. Heinrichs, J. A. Litsinger, K. Moody, L. Fieldler, T. W. Mew, A. T. Barrion
Illustrated Guide To Integrated Pest Management In Rice In Tropical Asia, W. H. Reissig, Elvis A. Heinrichs, J. A. Litsinger, K. Moody, L. Fieldler, T. W. Mew, A. T. Barrion
Entomology Papers from Other Sources
In the past, farmers in tropical Asia grew traditional rice cultivars and either relied primarily on cultural, mechanical, and physical methods of pest control or practiced no pest control. Pesticide application was limited because the yield potential of traditional varieties was too low to justify additional investments. Although pests destroyed part of each crop, severe outbreaks or epidemics were rare.
The widespread introduction of high-yielding rice cultivars in Asia in the last two decades and the associated changes in production practices have improved conditions for insects, diseases, weeds, and rodents. The higher yield potential of the new rices also made …

In Vitro Phosphorylation Of Maize Leaf Phosphoenolpyruvate Carboxylase, Raymond J. A. Budde, Raymond Chollet
Department of Biochemistry: Faculty Publications
Autoradiography of total soluble maize (Zea mays) leaf proteins incubated with 32P-labeled adenylates and separated by denaturing electrophoresis revealed that many polypeptides were phosphorylated in vitro by endogenous protein kinase(s). The most intense band was at 94 to 100 kilodaltons and was observed when using either [γ -32P]ATP or [β-32P]ADP as the phosphate donor. This band was comprised of the subunits of both pyruvate, Pi dikinase (PPDK) and phosphoenolpyruvate carboxylase (PEPCase). PPDK activity was previously shown to be dark/light-regulated via a novel ADP-dependent phosphorylation/Pi-dependent dephosphorylation of a threonyl residue. The identity of the acidstable 94 …
Species-Specific Restriction Site Polymorphism In Root-Knot Nematode Mitochondrial Dna, Thomas O. Powers, E. G. Platzer, Bradley C. Hyman
Species-Specific Restriction Site Polymorphism In Root-Knot Nematode Mitochondrial Dna, Thomas O. Powers, E. G. Platzer, Bradley C. Hyman
Department of Plant Pathology: Faculty Publications
Research was initiated to physically characterize the mitochondrial genomes of several Meloidogyne spp. and host-races, to address questions regarding their systematics and dispersal, and to assess the possibility of developing molecular diagnostics for these nematodes. Techniques were developed for purification and rapid detection of mitochondrial DNA from root-knot nematodes. Mitochondrial DNAs among Meloidogyne spp. were demonstrated to exhibit extensive divergence. The potential for using the rapidly diverging mitochondrial genomes as a diagnostic assay for M. incognita, M. hapla, M. arenaria, and M. javanica is discussed.

Development Rates For The Seed Maggots Delia Platura And D. Jlorilega (Diptera: Anthomyiidae), James E. Throne, C. J. Eckenrode
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Duration of immature stages of seedcorn maggots (SCM), Delia platura (Meigen), and bean seed maggots (BSM), D. florilega (Zetterstedt), was determined at eight constant temperatures from 5 to 40°C. No SCM or BSM survived to second instar at either 5 or 40°C. No BSM survived to the adult stage at 35°C. Duration of immature stages varied from 240 days at 10°C to 17 days at 35°C. A computer model developed using the SCM development rate data closely simulated SCM development in the field during the growing season.

A Temperature-Sensitive Chlorophyll Β-Deficient Mutant Of Sweetclover (Melilotus Alba), John P. Markwell, Stephen Danko, Hermann Bauwe, John Osterman, Herman Gorz, Francis A. Haskins
Department of Agronomy and Horticulture: Faculty Publications
The ch4 mutant of sweetclover (Melilotus alba) has previously been demonstrated to be partially deficient in chlorophyll and to have a higher ratio of chlorophyll a to b than normal plants. We were able to substantiate these findings when plants were grown at 23°C and lower (permissive temperatures). However, when grown at 26°C (nonpermissive temperature) the plants produced small yellow leaves which exhibited one- twentieth the chlorophyll content of normal plants. Affected leaves did not increase their chlorophyll content when plants were incubated at permissive temperatures, but leaves which developed at the lower temperature contained increased amounts of …
Quinoline Sorption To Subsurface Materials: Role Of Ph And Retention Of The Organic Cation, John M. Zachara, Calvin Alnsworth, Larry Felice, Charles Resch
Quinoline Sorption To Subsurface Materials: Role Of Ph And Retention Of The Organic Cation, John M. Zachara, Calvin Alnsworth, Larry Felice, Charles Resch
United States Department of Energy: Publications
The sorption of quinoline (pKa = 4.94) was investigated on low-organic-carbon subsurface materials that varied in pH. Sorption isotherms were measured from 10-7 to 10-4 M quinoline and were found to be nonlinear. The resulting Freundlich constants (KF), based on total aqueous quinoline concentration, were poorly correlated with subsoil properties, including organic carbon. Higher sorption in the acidic subsoils and favorable coefficents for regression of KF, normalized to cation-exchange capacity vs. the ionization fraction (Q), point to the importance of ion exchange of the protonated compound. When the subsoil pH …
Channel Catfish Virus Disease, John A. Plumb
Channel Catfish Virus Disease, John A. Plumb
United States Fish and Wildlife Service: Publications
Channel catfish virus disease (CCVD) is an acute infection of cultured fry and fingerling channel catfish (Ictalurus punctatus). The disease occurs primarily during summer and, with few exceptions, in fish less than 4 months old. The causative agent, the channel catfish virus (CCV), is a member of the herpesvirus group. Since its first identification (Fijan 1968), it has been isolated from infected fish in most areas of the United States where channel catfish are cultured.

Mid-Wintef Rood Use And Body Weights Of Mallard Sand Wood Ducks In Mississippi, Don Delnicki, Kenneth J. Reinecke
United States Fish and Wildlife Service: Publications
We obtained esophageal food samples from 311 mallards (Anas platyrhynchos) and 94 wood ducks (Aix sponsa) and body weights from 2,118 mallards and 315 wood ducks in western Mississippi during December and January 1979-83. On average, mallards ingested 3.0% animal food, principally aquatic invertebrates, and 97.0% plant food. Rice, soybeans, and seeds of "moist soil" plants provided 41.3, 41.6, and 10-11% of the total food intake. Wood ducks ingested nearly 100% plant food, of which 23.4% was soybeans and 74.3% was acorns from Nuttall (Quercus nuttallii), water (Q. nigra), and willow oaks (Q. phellos). Mallard food use varied with water …

Production Of Shiga-Like Toxin By Escherichia Coli, Lilian R. M. Marques, Marjorie A. Moore, Joy G. Wells, I. Kate Wachsmuth, Alison D. O'Brien
Uniformed Services University of the Health Sciences
Escherichia coli is one of several agents that cause intestinal disease in humans and animals. Four classes of E. coli have been recognized [1], Enterotoxigenic E. coli (ETEC) strains produce a heat-labile (LT) enterotoxin and/or a heat-stable( ST) enterotoxin. Enteroinvasive E . coli (EIEC) strains, like shigellae, penetrate and multiply within epithelial cells. Enteropathogenic E. coli (EPEC) strains belong to certain serogroups that have been incriminated as pathogens by epidemiological studies. Some EPEC strains have been shown to adhere to cells of the intestinal mucosa and to produce pathognomonic lesions at the site of attachment. Enterohemorrhagic E. coli (EHEC) strains …

Economic Evaluation Of Breeding Objectives In Sheep And Goats: Summary And Commentary, R. W. Ponzoni
World Congress on Genetics Applied to Livestock Production: 3rd (1986)
At the first and second World Congresses on Genetics Applied to Livestock Production some consideration was given to the definition of breeding objectives in sheep and goats. Having a whole Plenary Session dedicated to the evaluation of breeding objectives at the present Congress is an indication of the greater awareness about the importance of this area in the overall efficiency of breeding programmes. the chances of success of a breeding programme will be enhanced if during its formulation the following five steps are taken in meticulous order: (i) definition of the breeding objective; (ii) choice of selection criteria; (iii) organisation …

Characterization Of Milk Constituents Of Bos Taurus And B. Indicus × B. Taurus Breed Types, Donald R. Daley, Anne Mccuskey, Curtis M. Bailey
World Congress on Genetics Applied to Livestock Production: 3rd (1986)
Milk from eight Bos Taurus and Bos indicus × Bos Taurus breed types (n=128) was evaluated for percentage butterfat, protein, lactose and solids- non-fat. Milk samples were collected at approximately 60, 105, and 150 d after the onset of lactation by hand-milking the left front quarter following a 30-IU injection of oxytocin. Breed type variation was significant for some milk component traits at each stage of lactation. Brahman × Angus dams increased in component yields (kg) as lactation progressed; production levels of other breed types remained approximately the same or declined. Sex of calf influenced (P<.05) yield (kg) of protein, butterfat and solids-non-fat at 105 d only. Mastitis effects caused a reduction (P<.01) in percentage of lactose. Residual correlations between yield (kg) of milk components and weaning weight were all positive and significant.

Genetic Diversity Among Cattle Breeds And Its Use To Increase Beef Production Efficiency In A Temperate Environment, Larry V. Cundiff, Keith E. Gregory, Robert M. Koch, Gordon E. Dickerson
World Congress on Genetics Applied to Livestock Production: 3rd (1986)
Results are reviewed from the cattle Germ Plasm Evaluation Program at the Roman L. Hruska U.S. Meat Animal Research Center comparing performance of top-crosses by 20 sire breeds. The variation that exists in biological traits important for beef production is vast and under a high degree of genetic control. Significant genetic change can result from 1) selection among breeds, 2) use of crossbreeding to exploit heterosis and 3) selection within breeds. Estimates of the range for differences between breed means vary from 2.5 to 6.3 phenotypic standard deviations (σp) and exceed 4σp for most traits. The range for differences between …

Between-breed variation in body weight, food intake, carcass composition, milk yield, efficiency of food conversion during growth and maintenance efficiency in adult cattle was examined in a multibreed experiment at the AFRC Animal Breeding Research Organisation. Females from 11 beef , 8 dual-purpose and 6 dairy breeds were fed a complete pelleted diet (AA6) ad libitum from weaning at 12 weeks of age until the birth of their third calf. Females were mated by AI to produce both purebred and crossbred progeny which were reared under the same conditions and slaughtered at either 24, 48 or 72 weeks of age. …
Evaluation Of Industry Breeding Programs For Dairy Cattle Milk And Meat Production, Franz Pirchner
Evaluation Of Industry Breeding Programs For Dairy Cattle Milk And Meat Production, Franz Pirchner
World Congress on Genetics Applied to Livestock Production: 3rd (1986)
In most European."dual purpose breeds beef merit is paid attention to by selection among performance tested bulls where comparatively much weight is given to growth rate of performance pasted bulls and relatively little weight to muscling and thus to carcass meat content. The genetic correlation between beef and dairy merit appears to be negative. This, in combination with large ad effective selection pressure on milk leads to negating the effects of the little and relatively inaccurate selection for beef merit at the best. Field progeny testing for beef merit can be economical and will permit to neutralize or even improve …

Genetic Improvement For Milk And Meat Production In The Tropics, N. Künzi, W. Kropf
World Congress on Genetics Applied to Livestock Production: 3rd (1986)
Theoretical and practical ways to improve meat and milk production in the tropics by selection within local Bos indicus breeds, within Bos taurus x Bos indicus composite populations, upgrading of Bos indicus with Bos taurus breeds and though different crossbreeding programs have been discussed by various authors and summarized by Mason and Buvanendran (1982), Gregory et al. (1982) and Hickman (1979). Only few publications (Auriol, 1984; Chacko et al., 1985; Donegan and Roberts, 1984) exist on successful programs but numerous reports in developing agencies (FAO, 1985; SDC, 1985) indicate that many possibilities have been exploited and that various …
Buffalo For Meat Production, Giovanni De Fanciscis
Buffalo For Meat Production, Giovanni De Fanciscis
World Congress on Genetics Applied to Livestock Production: 3rd (1986)
Only very recently buffaloes have been studied deeper for a better breeding and for emphasizing their meat productive potentiality and its physiological, chemical and organolptic qualities.
Very good investigations, conducted mainly in Australia, Bulgaria, Italy, Thailand and Trinidad show in an univocal way, if the buffaloes are reared and fed well, that the daily gain, the percentage of fessing and of the first cut, the organoleptic characteristics are quite similar and sometime also better than those of bovine cattle. The best slaughter tiie is at 14-16 months of age when the live weight is of 350-380 kg with a 52-58 …
