Studies On The Helminth Fauna Of Alaska. Xl. Strigea Gruis Sp. N., A Trematode Parasite Of Grus Canadensis (L.), Georges Dubois, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Strigea gruis sp. n. (Trematoda: Strigeata, Strigeidae) is described from the sandhill crane Grus c. canadensis (L.). Only one other species of Strigea (S. neotidis Bisseru, 1956) is known from birds of the order Gruiformes; it is distinguished from S. gruis by several characteristics including its slender form, campanulate anterior segment, size of pharynx and of eggs, position of ovary, and position and size of testes. S. gruis differs from two other species having a relatively large pharynx, S. sphaerula (Rudolphi, 1803) and S. intermedia Szidat, 1932, both parasites of corvids, in the form of the anterior segment and …

Electromyographic Analysis Of The Temporal And Masseter Muscles During The Para-Retentional Period In Orthodontic Patients, Thomas L. Thompson

Loma Linda University Electronic Theses, Dissertations & Projects

This study was initiated to compare electromyographically the activity of the masseter and temporal muscles during the early retentional period in orthodontic patients. Electromyographic recordings were taken at the following times: (1) before typical edgewise appliance was removed, (2) at time of retainer insertion, (3) after eight to twelve weeks of retainer wearing, and (4) one day following occlusal equilibration. Electromyograms from the orthodontic group of subjects were compared with electromyograms from a group of subjects with normal occlusion, and a group of subjects with untreated Class II, Division 1 malocclusions. There was a total of thirteen subjects studied: five …

The Effect Of Varying Protein Intake On Trichinella Spiralis Infection In Mice, Clare K. Kwan

Loma Linda University Electronic Theses, Dissertations & Projects

Three hundred Swiss Webster albino mice three weeks of age were placed on low (8%), medium (24%), high (48%) protein levels and a commercial laboratory animal feed, Purina Chow for various lengths of time: (1) simultaneously with infection, and four weeks thereafter, (2) three weeks before infection and throughout the four-week infection period, and (3) six weeks prior to infection and during the infection period. The protein source was casein. Sixty of the 300 mice used served as noninfected controls, and the other 240 were each infected with 400 washed, suspended Trichinella spiralis larvae obtained from a rat by the …

Coccidiosis Of Cattle, Datus M. Hammod

Faculty Honor Lectures

The disease known as coccidiosis occurs in many domestic and wild animals. It is of great importance in chickens, in which coccidiosis is one of the chief causes of losses to the producer. In cattle the disease was estimated by Fitzgerald in 1962' to cause an . annual loss of $3,500,000 in calves under one year of age in the 11 western states and $7,500,000 in the seven west north-central states. In making this estimate Fitzgerald calculated that 90 percent of all calves are infected by coccidia, and that the average loss amounted to 75 cents per head on all …

Concentrate Feed Handling Methods And Costs By Dairy And Beef Producers--Selected Utah Counties, 1961-1962, Kendell W. Brinkerhoff

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Utah is historically an agricultural state with many resources adapted to livestock production. The beef and dairy industries in Utah account for 40 and 15 percent respectively of the total receipts received from agricultural marketings (7). Utah's resources are less adapted to poultry production compared to livestock production. Nevertheless, poultry production represents a significant portion of the total agricultural receipts. Production of livestock and poultry have expanded beyond the state's capacity to produce concentrate feed to benefit from economy of scale and to increase farm size through intensification. This feed deficit in Utah must be supplied from sources outside the …

Isolation And Preliminary Characterization Of Bacteriophage Φμ-4, Fred Shafia, T.L. Thompson

Papers in Microbiology

Isolation and preliminary characterization of bacteriophage Φμ-4. J. Bacteriol. 87:999-1002. 1964.-Bacteriophage Φμ-4 was isolated from lysogenic Bacillus stearothermophilus NU strain 4, and was propagated in strain 10 of the same species. The phage was extremely host-specific. One of the 23 strains of thermophiles screened for susceptibility supported phage replication. Plaque-forming efficiency of Φμ-4 depended on the agar medium employed and the temperature of incubation. Generally, media which resulted in restricted growth of the host cells on agar plates were most satisfactory for plaque formation. A latent period of 35 min was terminated in cell lysis and release of about 175 …

Arctic Health Research Center, U.S. Public Health Service, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A program of research in Alaska was initiated by the United States Public Health Service in 1948, with the establishment of a field station in temporary facilities located at Anchorage. This station, officially designated the Arctic Health Research Center in May 1950, was founded largely as the result of surveys of health conditions in Alaska conducted during 1946 and 1947 by two committees representing the American Medical Association. The reports of these committees led Congress to pass a special appropriation bill to support the investigation of health problems in Alaska.

Six research sections were set up within the first year. …

Some Effects Of Accumulated Radium On The Productivity Of Algae, Joseph W. Angelovic

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ionizing radiation from natural occurring radionuclides and cosmic rays has always been a part of man's environment, but at such low levels as to have had virtually no effect. However, with the advent of the atomic age and the advancement of nuclear technology, background activity has measurably increased all over the world. Fallout from nuclear weapons testing, wastes from nuclear reactors, and wastes from the milling of radioactive ores have all contributed to this increase. Due to this increase, many ecosystems and their individual components are now subjected to radiation levels as high as a million times natural background. What …

A Study On The Biochemistry Of Riboflavin In Higher Plants As Influenced By Iron, Dayna L. Stocks

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Riboflavin, 6,7-dimethyl-9-(D-1'-ribityl) isoalloxazine, has been studied extensively by workers in many fields of interest. Because of its almost universal occurrence in plants and its requirement by most animals as a vitamin, it is of interest to both the botanist and the zoologist. It is also of interest to the photochemist and its photo chemistry is currently being studied by several groups (27, 35, 47, 49). In addition riboflavin has been implicated in the photo inactivation of indole-acetic acid (16) and 2,4-D (20). It is also thought to be involved in the processes of bioluminescence (33, 48) and phototropism (17). At …

A Study Of Certain Convenience Foods With Reference To Purchaser, Cost, And Nutritive Value, Naomi Jensen

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The various activities associated with the provision of food for feeding of the family traditionally have been functions of the home . One of the major enterprises of the homemaker in past years was to plan , produce or purchase , preserve , and prepare food daily for the family. The role of the homemaker today has changed from one of producer to one of purchaser. Hence, at least weekly, the selection of food at the market place involves not only the best use of her time but wise expenditure of her food budget. The market is changing so rapidly …

Weight Reduction Problems As Shown By A Review Of Literature And A Survey Of Weight Reduction Groups, Naomi Jensen

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

America has been known throughout its history as a land of plenty . Enough food to feed a rapidly increasing population has been produced continuously . Scientific progress has made it possible for fewer farm workers to produce larger amounts of food both from increased acreage and increased yield per acre . With today's nationwide network of distribution , these foods have been made available throughout all sections of the country . Modern science and industry have taken over many of the processing duties of the homemaker and have done it on a less expensive and a much safer scale. …

Neutral 17-Ketosteroids And 17, 21-Dihydroxy-20-Ketosteroids In Urine Of University Students, Shon-Hua Yu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Degenerative disease of old age such as atherosclerosis and cerebral hemorrhage appear to be related to abnormal lipid metabolism. Many investigators have studied the role of steroid hormones on lipid and cholesterol metabolism in rats and chickens. The results have consistantly indicated that both corticosteroids and sex hormones play an important role in the regulation of lipid and cholesterol metabolism, in vivo. Serum cholesterol values in humans have been decreased by estrogens, while androgen administration tends to increase circulating cholesterol. Estrogens have been shown to decrease circulating cholesterol and prevent cholesterol-induced coronary atherosclerosis in chickens. A study of the …

Effects Of Hydro-Cooling, Chemicals, And Packaging Treatments On Refrigerated-Life And Quality Of Sweet Cherries And In Vitro Effects Of Chemicals On Selected Fungi Responsible For Fruit Deterioration, Joseph Yungsheng Do

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As the population tends to urbanize, the potential consumer market of fresh produce becomes distant from the producing farm. This distance brings to growers and handlers the problems of how to keep their fresh products unspoiled after harvest and during transit period of shipping, and how they can be delivered to the specified destination without substantial deterioration. It is the common interest of fruit growers, shippers, wholesalers, and retailers that the shelf-life of fresh fruit be prolonged to increase sales.

Sweet cherries are one of the important fruit crops in Utah. Being highly perishable, fresh sweet cherries have relatively short …

Increasing Income From South Dakota Resources: Papers Presented At The Third Annual Agri-Business Day, South Dakota Agricultural Experiment Station, Department Of Economics, South Dakota State University

Agricultural Experiment Station Agricultural Economics Pamphlets (1941-1991)

As increasing income is closely related to resource development, the Agri-Business Day Program was structured to include a consideration of resources most directly influencing levels of personal income. This program was divided into three major parts. The first primarily concerned ways to expand economic activity and higher levels of income through development of human resources. Human resource development was placed at the head of the program as it is recognized that all economic development has its inception in the thinking processes of man. The second part of the program was built around ways of generating income through the development of …
