A Comparative Roentgenographic Cephalometric Study Of The Facial Profile Of Orthodontic Patients Treated At Loma Linda University With Winners Of The "Smiles Of The Year" Contest, Romeo I. Stoll

Loma Linda University Electronic Theses, Dissertations & Projects

The "Smiles of the Year" winners and patients treated at Loma Linda University by the extraction or non-extraction approach were compared by linear and angular variables of skeletal, dental and soft tissue components. These findings were analyzed statistically to determine significant differences in the profile and detect the relationship between the integument and hard structures.

The following conclusions were drawn from this investigation to reflect the trend of treatment at Loma Linda University.

1. After treatment the patients had less skeletal convexity, but were more convexity than established standards.
2. The incisors of the patients treated by the extraction approach were less …

The Effect Of Chemical Competition On Thermodynamics Of Bacterial Adsorption, Deorao R. Khairnar

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The objective of this investigation was to study the effect of chemical competition on thermodynamics of bacterial adsorption. This was done using an experimental system consisting of Mendon silt loam soil as the adsorbent, Staphylococcus aureus as a common adsorbate and sodium chloride (NaCl), sodium lauryl sulfate (SLS), and peptone as competitive adsorbates.

The bacterial adsorption on soil both with and without chemical competition followed Langmuir type isotherms. From the equilibrium data, thermodynamic functions such as free energy, ΔF°, enthalpy, ΔH°, and entropy, ΔS°, were calculated. Observed positive ΔH° values indicated that the bacterial uptake in both noncompetitive and competitive …

Magnesium Ion Inhibition Of Calcium Carbonate Precipitation And Its Relation To Water Quality, John J. Hassett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effect of Mg⁺⁺ ion on the solubility of calcium carbonate was determined using P. K. Weyls "carbonate saturometer."

The amount of calcium carbonate precipitated or dissolved was measured for five series of waters when equilibrated with solid carbonate.

It was found that the effect of Mg⁺⁺ ion on solubility depend upon the nature of the solid phase: surface area, coprecipitated Mg⁺⁺, minerology, etc.

Pure low area calcite showed an increase in solubility which could be explained by ion-pair formation, while its other carbonates departed from this behavior.

Vertebrate Pest Conference Proceedings: 4th (1970)

PROCEEDINGS: FOURTH VERTEBRATE PEST CCONFERENCE held at El Rancho Hotel, West Sacramento, California, March 3, 4 and 5, 1970. Edited By Richard H. Dana, Conference Chairman. Sponsored by the California Vertebrate Pest Committee

Opening Remarks - Fourth Vertebrate Pest Conference, Richard H. Dana

Vertebrate Pest Conference Proceedings: 4th (1970)

I am pleased to welcome you to the Fourth Vertebrate Pest Conference. This is our second Sacramento meeting. The first was in 1962 - eight years ago. It was an historic occasion. It was the first conference devoted exclusively to vertebrate pests. This conference is sponsored by the California Vertebrate Pest Committee comprised of representatives from the California Department of Agriculture, the University of California at Davis, Department of Animal Physiology and the Agricultural Extension Service; the U. S. Bureau of Sport Fisheries and Wildlife, Division of Wildlife Services and of Wildlife Research, the California Departments of Public Health, Fish …

Keynote Address --- "The Year Of Ecology", Robert I. Cushing

Vertebrate Pest Conference Proceedings: 4th (1970)

It seems to me that there are at least two things we should be concerned about. First, I believe there is a real possibility that the environmental quality bandwagon will get to playing so loud and to rolling so fast that there can be some unfavorable consequences in food production and processing-—the job I work at and that some of you work at. Second, I believe there are signs that we could lose our balance—-that we could be making decisions on emotional instead of rational grounds. Reason seems to be in danger from an epidemic of emotion. And we need …

Outlook For Rodenticides And Avicides Registration, James O. Lee

Vertebrate Pest Conference Proceedings: 4th (1970)

The history of pesticide regulations is presented. Major emphasis is on federal regulations. The evaluation of avicides and rodenticides is discussed and related to regu¬lations. Currently registered avicides and rodenticides are described along with a listing of efficacy criteria requirements. The future of registration of avicides and rodenticides is projected.

The Pharmacology Of Rodenticides, S. A. Peoples

Vertebrate Pest Conference Proceedings: 4th (1970)

The compounds used as rodenticides are tremendously varied in their chemical structure and mechanism of action. With a few exceptions, these agents are generally poisonous to all animals, including man, and a great deal of study has been directed to their toxicity in animals other than rodents. However, the development of new compounds as Norbormide and certain antifertility drugs which are highly selective in their action may justify the hope that the ideal rodenticide free of secondary toxic hazards will soon be available. Until this happy announcement is made, a review of the pharmacology of the older compounds is in …

Notes On The Ecology Of Sewer Rats In St. Louis, Kyle R. Barbehenn

Vertebrate Pest Conference Proceedings: 4th (1970)

The awareness, if not the magnitude, of problems caused by sewer rats has increased in the United States in recent years. Thus, current concern with the more general problem of urban rats is leading many city agencies to incorporate plans for controlling sewer rats in budgets that are already severely strained. The most effective programs for controlling pests are those based on an intimate knowledge of the interactions between the target species and its environment. Some basic studies of sewer rat ecology were begun in St. Louis, Missouri, in February, 1969. Since the initial results have provided information that should …

The Role Of The Coyote In An Infection Of Man And Animals, I. K. M. Liu

Vertebrate Pest Conference Proceedings: 4th (1970)

As part of epidemiological studies on hydatid disease in the central valley of California, a survey was made of seven counties of possible infections with Echinococcus granulosus in the coyote (Canis latrans). Of 173 animals examined, seven 4.O per cent) were found infected, six of them from Tehama County.

Current Status Of Plague And Plague Control In The United States, Jack D. Poland, Allan M. Barnes

Vertebrate Pest Conference Proceedings: 4th (1970)

During the first quarter of the 20th century massive rat-borne plague epidemics occurred in port cities of the United States in conjunction with the last world-wide pandemic which originated in China in 1893. By 1950, plague was found to be firmly established in wild rodent populations in states west of the 100th meridian. Presumably because of improved sanitation coupled with retreat of the world-wide pandemic there have been no human cases in this country associated with urban rats since 1924. However, sporadic cases, fewer than 10 per year, are reported as due to contact with wild rodents, lagomorphs, rural rats, …

The Rat In Hawaiian Sugarcane, Glenn A. Hood, Roger D. Nass, Gerald D. Lindsey

Vertebrate Pest Conference Proceedings: 4th (1970)

Heavy losses In Hawaiian sugarcane are caused by Polynesian rats (Rattus exulans), Norway rats (R. norveglcus), and black rats (R. rattus). Relative population levels, movement patterns, damage to sugarcane, and suggested timing of control during five stages of the 2-year crop cycle are described. The progress toward the registering of zinc phosphide for use in crops and the development of other rodenticides are mentioned.

Rodent Control In The Hawaiian Sugar Industry, Allen H. Teshima

Vertebrate Pest Conference Proceedings: 4th (1970)

Past and present concepts of rodent control at the 24 sugar plantations of Hawaii are reviewed with particular attention being given to the research efforts of the Experiment Station of the Hawaiian Sugar Planters' Association in improving operational rodent control in sugarcane. Hawaii offers a unique set of conditions: a 2-year crop cycle, a production of over 100 tons of sugarcane per acre, countless numbers of gulches and wasteland bordering crop fields, and a year-long growing season, all having an effect on rat population and habitat.

Vampire Bat Control: A Review And Proposed Research Programme For Latin America, Arthur M. Greenhall

Vertebrate Pest Conference Proceedings: 4th (1970)

In Latin America paralytic rabies transmitted by vampire bats is a major cause of death in cattle. This problem becomes more acute as countries attempt to increase livestock production to feed rapidly expanding human populations. Vaccination has been the principal weapon against rabies, however this offers no protection to domestic animals and poultry against daily predation of vampire bats. Established methods of vampire bat control, though limited, have proved effective and should be continued while more effective methods are being developed and tested. Existing methods are discussed in some detail. Of the approximately 200 kinds of bats found in Latin …

New Factors Controlling Populations Of Land Vertebrates In Great Britain, N. W. Moore

Vertebrate Pest Conference Proceedings: 4th (1970)

The vertebrate fauna of Britain is impoverished by nature. Further, virtually the whole land surface has been altered radically by Man, and all vertebrate species have been profoundly affected both unconsciously and consciously by Man. The rate of change during the last quarter of a century has been far greater than at any other time; new deleterious factors - increased habitat destruction, increased human pressure and motor traffic, myxomatosis and a vast increase in pesticide use have coincided in this period. The public's attitude to several common species (e.g., rabbit, woodpigeon, fox and birds of prey) has been equivocal and …

Importance Of Wildlife Rabies Control, Richard L. Parker

Vertebrate Pest Conference Proceedings: 4th (1970)

ABSTRACT: Rabies in animals has been known in North America for over two centuries, and whether the disease was initially present in wild species or was introduced by dogs, it has been known in skunks for almost a century and a half. Today more rabies cases in wild animals are reported than in domestic animals, and a considerable proportion of both human and domestic animal exposures to the disease are the result of wild-animal contact. The most useful techniques for controlling wild animal rabies today are methods that reduce contact between infected individuals and susceptible individuals; these involve the manipulation …

Chemosterilants As An Approach To Rodent Control, Rex E. Marsh, Walter E. Howard

Vertebrate Pest Conference Proceedings: 4th (1970)

Capitalizing on research directed toward oral contraceptives for humans, a wide variety of compounds are now under study for their practical value in inhibiting rodent reproduction to suppress detrimental populations. This paper discusses the specifications of ideal rodent chemosterilants and the advantages of chemosterilants over other methods of control, and compares the potential values of chemosterilants acting on females, males, and both sexes. Specific situations are detailed where chemosterilants will be most valuable in rodent control, together with proposed methods of application. Chemosterilants are not expected to become a panacea for control, but since they are based on sound biological …

Olfaction In Rodent Control, Walter E. Howard, Rex E. Marsh

Vertebrate Pest Conference Proceedings: 4th (1970)

A brief survey is presented of current knowledge on olfaction in rodents and the various roles that odors may play in modifying rodent behavior. Some species at least utilize olfactory cues: to locate food items; to recognize their mother and mates; to mark territory; as an involuntary population density regulator; possibly to recognize predators; as a warning cue against a repellent or toxic substance (poison-bait shyness); and probably, for many other behavioral purposes. The value of using artificial odors in rodent baits to increase bait acceptance is not yet well documented. The addition of attractive natural odors may increase detection …

Mole Control, Lee W. Kuhn

Vertebrate Pest Conference Proceedings: 4th (1970)

ABSTRACT: Four kinds of moles are found in the Pacific coast states but only the Townsend mole (Scapanus townsendii) in Washington and Oregon and the broad-handed mole (Scapanus latimanus) in California are considered economically important. Damage in agricultural areas is caused by mole mounds and burrow systems which reduce pasture production, make harvesting difficult by breaking or plugging machinery, contaminate hay and silage thus, retarding proper curing, contribute to soil erosion and make ready-made homes for invading meadow mice, pocket gophers, and other rodent pests. Moles also damage lawns, gardens, flower beds and occasionally eat or destroy valuable seeds and …

Destruction Of Conifer Seed And Methods Of Protection, M. A. Radwan

Vertebrate Pest Conference Proceedings: 4th (1970)

ABSTRACT: Agents responsible for tosses of conifer seed and methods for seed protection are reviewed. Published information indicates that much seed is destroyed, especially by seed-eating rodents and birds. Improvement of existing protective methods and development of new chemical means are necessary to overcome the problem.

Studies In Microencapsulation Of Rodenticides, P. B. Cornwell

Vertebrate Pest Conference Proceedings: 4th (1970)

Warfarin, zinc phosphide, norbormide and alphachloralose have been microencapsulated by the technique of coacervation and fed to laboratory rats (R. norvegicus) and mice (M. musculus). Results are given of experiments in which the concentration of rodenticide, wall material and phase ratio have been varied separately and in combination. Experiments are also reported in which normal and encapsulated rodenticide has been fed together in the same test diet.

Trapping - The Oldest Profession, William D. Fitzwater

Vertebrate Pest Conference Proceedings: 4th (1970)

While trapping is probably the oldest pursuit of man, predating hunting and agriculture, it has not undergone many drastic changes since the first primitive attempts. An arbitrary classification of traps [improvised traps, snares-and nets, cage traps, spring traps and glues] is discussed and examples of each group given. As the behavioral and physical characteristics of vertebrate animals vary so much, it is impossible to discuss trapping procedures in any detail, but certain principles apply to most situations. These are: (1) need for an understanding of the target species' habit patterns, (2) selection of a trap size and design suitable for …

Methods Of Controlling Jackrabbits, James Evans, Paul L. Hegdal, Richard E. Griffith Jr.

Vertebrate Pest Conference Proceedings: 4th (1970)

Since 1963, biologists of the Denver Wildlife Research Center have been investigating methods of alleviating agricultural damage by the black-tailed jackrabbit (Lepus californicus). Of the several approaches to control, most biological methods (predation, habitat manipulation, disease and parasites, and chemosterilants) appear impractical with present knowledge. Mechanical control except for fence barriers, usually has limited effectiveness. Currently, the most useful approach is still chemical control. Improved baiting techniques and several chemical control agents, including an experimental toxicant highly selective for jackrabbits, are described.
