Faculty Publications
Incubation of mouse myeloma microsomes with GDP-[(14)C]mannose results in the biosynthesis of [(14)C]mannose phosphoryl dolichol [Baynes, J. W., Hsu, A.-F. & Heath, E. C. (1973) J. Biol. Chem. 248, 5693-5704] and a [(14)C]mannose- and N-acetylglucosamine (GlcNAc)-containing oligosaccharide derivative of dolichol. Thus, [(14)C]mannose phosphoryl dolichol and [(14)C]mannose-labeled oligosaccharide pyrophosphoryl dolichol were isolated from incubation mixtures by solubilization in 2% (w/v) Triton X-100 and the lipids were separated from small molecules by gel filtration fractionation. After removal of radioactive protein from the preparation, the two lipid derivatives were separated quantitatively by fractionation on a concanavalin A-Sepharose column; [(14)C]mannose phosphoryl dolichol was not …
A Cephalometric Study Of Mandibulo-Facial Disostosis In Monozygotic Twins Using Computerized Methods, Lyn M. Lamberton
A Cephalometric Study Of Mandibulo-Facial Disostosis In Monozygotic Twins Using Computerized Methods, Lyn M. Lamberton
Loma Linda University Electronic Theses, Dissertations & Projects
An investigation using computerized cephalometrics has been conducted to consider the cephalometric factors responsible for the characteristic appearance evident in individuals afflicted with Mandibulo-Facial Dysostosis. A pair of Negro monozygotic affected twins were studied using the other 10 non-affected members of the family as a control to minimize the environmental and hereditary factors. The Rocky Mountain Data System was utilized to analyze the lateral and frontal cephalometric radiographs of each individual using Ricketts Analysis and the data were subjected to statistical tests to determine the factors contributory to the syndrome. Age and size were considered and adjustments were made to …

In order to investigate the characteristics of the facial complex of the Mexican and to compare them with the Caucasian, a sample of 40 subjects, 31 males and nine females, of Latin American origin from Chihuahua, Chihuahua, Mexico, with a mean age of 16.6 years, were selected for this study. The criteria for selection were visual and only individuals with clinical normal, Angle Class I occlusion were chosen.
Lateral head Roentgenograms were obtained and cephalometric evaluation of the Skeletal and Dental Pattern was carried out using the Ricketts, Steiner, and Tweed Analyses.
The mean values for the Mexican were compared …
Effects Of Cocaine, Nicotine And Diet On Voluntary Alcohol Consumption In Rats, Zaida Raquel Cordero Loayza
Effects Of Cocaine, Nicotine And Diet On Voluntary Alcohol Consumption In Rats, Zaida Raquel Cordero Loayza
Loma Linda University Electronic Theses, Dissertations & Projects
The consumption of alcohol is a problem not only in this country (U.S.), but also in many other places in the world. Thus we find the Indians in Peru, Bolivia and other neighboring countries (Ecuador and northern part of Argentina) consuming alcohol to the point that they become alcoholics, in addition to this they also chew coca leaves, plant from which cocaine is extracted.
In an effort to establish the cause for this behavior, we put Sprague-Dawley albino rats on either a poor or good basal diet. Once every other day the rats were injected with a solution of cocaine. …

Are Nuclear Shipments Really Safe?, William A. Brobst
Are Nuclear Shipments Really Safe?, William A. Brobst
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
The transportation of nuclear materials is on the increase. Although nuclear shipments are only a very small fraction of the Nation’s hazardous materials shipments, they attract a great deal of public attention. Shipments of spent nuclear fuel and nuclear wastes are a particular concern.
One of the many fears that people have about nuclear energy is the possibility that a nuclear shipment might somehow go awry and cause a serious public hazard. Primarily, they are worried that a shipment of spent reactor fuel or highly radioactive waste could be involved in a serious rail or highway accident and dump its …

Energy And The Environment, Joseph T. Zung
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
The topic of Energy and Environment is probably the most timely one at present time. Probably it is not because both energy and environment are man's most precious resources we want to conserve, but because of their seemingly contradictory and mutually destructive nature. One often asks ourselves these days: Is the energy crisis an environmental problem or environmental restrictions caused our present energy crisis?

Let me share with you a quotation from a report issued bv the Chase Manhattan Bank while the Arab oil embargo was still in effect. "Reportedly, the annual cost of a gasoline rationing program would amount to $1.4 billion. Based upon past results, if that much money was devoted to an exploratory effort, it would be potentially capable of discovering more than 2 billion barrels of petroleum. That amount of petroleum would be equal to 19 percent more than all the gasoline consumed in privately owned automobiles in 1973."
While the threat of rationing has disappeared with an end to …

International Regulation Of Marine Pollution From Land-Based Sources, Richard Tucker Scully
International Regulation Of Marine Pollution From Land-Based Sources, Richard Tucker Scully
Marine Affairs Theses and Major Papers
Most of the waste products of human society end up in the oceans and the number and quantities of pollutants entering the oceans have been increasing at exponential rates. Recognition of these trends has resulted in expansion of international environmental attention to include sources of marine pollution other than vessels. Source, in this sense, refers to the pathway through which pollutants reach the sea. Land-based sources accounts for the vast bulk of the pollutants reaching the oceans. Effective protection of the marine environment, therefore, must include regulation of land-based sources of marine pollution.
The Perplexities Of The U. S. Marine Transportation System, Stewart B. Nelson
The Perplexities Of The U. S. Marine Transportation System, Stewart B. Nelson
Marine Affairs Theses and Major Papers
The U. S. merchant marine, today, is struggling to attain physical and economic health, but it is a formidable undertaking since approximately 95 percent of U. S. ocean-borne trade is currently being carried by foreign flag vessels. As used in this paper, the marine transportation system will focus upon the "well-balanced" aspects of maritime activities. Emphasis will be placed on the carriage of water-borne commerce and related supportive activities and industries. This paper, with only the broadest of perspectives, attempts to make some general comments concerning the economies of the marine transportation system and the interrelationships between marine transportation modes …
The Tanker And Ocean Oil Pollution, Raymond Coombs
The Tanker And Ocean Oil Pollution, Raymond Coombs
Marine Affairs Theses and Major Papers
It is now clear that the capacity of the oceans to accept some of the by-products of civilization is limited. The oceans can no longer be the world's sink, it we are to maintain the ecological viability of the biosphere. The dangers of the present situation are compounded by the difficulties in defining "marine pollution." Today's concern with pollution and its effects upon our way of life requires that the impact of ships on the marine environment be considered in order to minimize the risk that waterborne cargoes, particularly petroleum products, present to the ecology.

Bulletins - 3000 - 3999
Western Australia has a small dairy industry compared with its other rural production. However, the industry has consolidated over recent years.
Tree clearing and pasture development on existing holdings and the amalgamation of small dairy farms has led to a rapid increase in the area of pasture per farm. The trend in Western Australia is towards bigger herds, more efficient dairies, more fodder conservation and increasing production per cow and per· hectare.

Macrocyclic Polyether Sulfide Syntheses, The Preparation Of Thia-Crown-3, 4, 6, And 7 Compounds, Yau-Kwong Joseph Hui
Theses and Dissertations
Macrocyclic polyether sulfides have been prepared by reacting an oligoethylene glycol dichloride with a dithiol or sodium sulfide in ethanol. The following new compounds were prepared: 1-thia-(9-crown-3), 1,4-dithia-(9-crown-3), 1,4-dithia-(12-crown-4), 1,4,7-trithia-(12-crown-4), 1-thia-(18-crown-6), I,4-dithia-(18-crown-6), 1,7-dithia-(18-crown-6), 1,4,7-trithia-(18-crown-6), 1,7-dithia-(21-crown-7), 1,4,7-trithia-(21-crown-7). Four other previously reported macrocyclic polyether sulfides were also prepared. The symmetry of the nmr spectra of these compounds give added evidence for the proposed ring structures. The following subjects were presented and discussed: studies of cyclization by-products, dependence of cyclization yield on the size of the rings, high dilution principle and its application, medium-sized rings, effect of hetero-atoms on cyclization and melting point …
The Use Of Transactional Analysis With Inquiry Methods In Physics Teaching, Robert Fuller, Ward L. Sims
The Use Of Transactional Analysis With Inquiry Methods In Physics Teaching, Robert Fuller, Ward L. Sims
Robert G. Fuller Publications
We now offer a course that combines an inquiry approach to physics with elementary school science teaching methods and transactional analysis. Our course carries three semester credits in elementary science methods and three semester credits in physics, a total of nine contact hours per week. In previous interim courses the very positive response we have had from our students, i.e., the excitement in discovering some real physics for themselves, and their decision to use the tools of transactional analysis to say "OK" to themselves and physics, leads us to believe that our course can serve as a useful model for …
Lakeside Homes Around Tuttle Creek Reservoir: An Element In The Local Settlement Fabric, Gary Lee Henton
Lakeside Homes Around Tuttle Creek Reservoir: An Element In The Local Settlement Fabric, Gary Lee Henton
Student Work
'l'he construction of several large reservoirs in the Midwest has brought about the growth of innumerable ancillary developments. The increased number of new homes, located adjacent to the reservoirs represents a growing component of our settlement fabric. Geographers have done studies on recreational developments, (Wolfe, Roy L., "Summer Cottages in Ontario"1 Howes, Robert· M., "Recreational Opportunities Arising from Reservoir Construction,"2) but little published investigation has been done in the Kansas, or Nebraska area. How important are the lakeshore homes now, and what part will they play in future housing? Who are the people currently occupying these structures? Where do they …
Trace Metal Analysis Of Hair By Charged Particle X-Ray Fluorescence, George M. Allison
Trace Metal Analysis Of Hair By Charged Particle X-Ray Fluorescence, George M. Allison
Theses and Dissertations
A method for the trace element analysis of hair by charged particle X-ray fluorescence is presented. The validity of the method is shown by the analysis of NBS SRM 1577--Bovine Liver, obtained from the National Bureau of Standards. Excellent correlation is obtained between results from the analysis by the X-ray method and those certified by NBS. Hair samples are ashed by a low temperature oxidation process and analyzed by the X-ray method. The results from the analysis by the X-ray method are compared to those obtained from the analysis of the same hair samples by atomic absorption. Good correlation is …
A Calorimetric Study Of Metal Binding In Carboxypeptidase, Carbonic Anhydrase And Concanavalin A, Gary E. Hatch
A Calorimetric Study Of Metal Binding In Carboxypeptidase, Carbonic Anhydrase And Concanavalin A, Gary E. Hatch
Theses and Dissertations
The purpose of this study was to perfect a new calorimetric method for identifying and counting ionizable chemical groups on proteins. To do this, calorimetric and electrometric titrations were performed (using HCl and NaOH as titrant) on native carboxypeptidase, carbonic anhydrase and concanavalin A plus their apo and organic ligand bound derivatives. Readily identifiable endpoints were seen in the calorimetric titrations and general agreement was found between ΔH values obtained in this study and literature ΔH values of model compounds undergoing the same reaction. Imidazole groups were those most easily counted. Many assumptions had to be made, however, in concluding …

A Review Of Coyote Control Research, Donald S. Balser
A Review Of Coyote Control Research, Donald S. Balser
Vertebrate Pest Conference Proceedings: 6th (1974)
Research on coyote control has lagged behind operational control for several decades. With the current controversy over toxicants and control of coyotes, attention has suddenly been given to the research needs of the problem. In the past research on annual damage problems, particularly predators, was concentrated on coming up with new lethal methods. The picture has changed with a definite need to study the entire problem, including the measurement of losses, the ecology of predators and prey, their behavior, and means of solving loss problems by non-lethal methods or mechanical protection. In any lethal control research, selectivity must be emphasized. …
Pest Management In Relation To Human Health, Allan M. Barnes
Pest Management In Relation To Human Health, Allan M. Barnes
Vertebrate Pest Conference Proceedings: 6th (1974)
Vector-borne disease prevention and control strategies, aside from those associated with domestic rodents, have rarely involved management of vertebrate populations, even though in many cases such management would appear to represent the most effective and economical long-term approach. Prevention of a long list of arthropod transmitted diseases is often at best a stop-gap procedure undertaken only after substantial disease hazard is detected in reservoir populations. More often, control actions await the detection of human cases, at which time short-term emergency control measures may be conducted, usually involving the use of toxicants against arthropod vectors and occasionally vertebrate reservoirs. In some …
An Overview Of Astm's Activities In Establishing Standards For Vertebrate Pest Control Materials, John R. Beck
An Overview Of Astm's Activities In Establishing Standards For Vertebrate Pest Control Materials, John R. Beck
Vertebrate Pest Conference Proceedings: 6th (1974)
The new FEPCA legislation under which a l l of us now operate, changes the format and program of pesticide registration and use in the United States. One of the events immediately proceeding this law was the establishment of the United States Environmental Protection Agency, and the necessity for that new agency to develop guidelines and standards for the registration and use of pesticides. Early in 1973, a large number of persons associated with one or more areas of pesticides, and representing the academic world, consumers, and producing companies, assembled in Philadelphia to discuss with the American Society for Testing …
A Review Of Rodent Control Programs In New York State, Joe E. Brooks
A Review Of Rodent Control Programs In New York State, Joe E. Brooks
Vertebrate Pest Conference Proceedings: 6th (1974)
The history of rodent control programs in New York State is reviewed, beginning with state-funded efforts in August, 1967. In 1969, Federal rodent control grant funds were used to establish four Model Cities programs. At its peak in 1970, programs were active in 18 counties, eight cities and villages, and in six Model Cities areas. The program encompasses all the major metropolitan areas of the state, serving some nine million persons. As part of the state program, the Rodent Control Evaluation Laboratory was established to investigate chemosterilants as a means of rodent control and to develop knowledge of pest rodent …
