Studies On The Periodicity Of Certain Plankton Species Of Salem Lake, Gene A. Pratt

Theses and Dissertations

Plankton samples were taken periodically from one station in Salem Lake from the fall of 1955 through the winter of 1957. Other data including the pH, dissolved oxygen content, turbidity, brightness of day, temperature, and time of day were recorded at the time of each collection. The plankton samples were centrifuged and preserved in a 4% formalin solution. They were later examined microscopically, and density, percent density, and percent frequency calculations were made from them for ten selected species and for the five phyla which they represent.

Observations On The White-Faced Ibis, Plegadis Chihi, In Louisiana, Horace William Belknap

LSU Historical Dissertations and Theses

The eight-month study deals with the White-faced Ibis, Plegadis chihi, in southwestern Louisiana. It affirms the absence of the closely related Glossy Ibis, Plegadis falcinellus, as a breeding bird in that area today. Data on feeding habits, social behavior, nesting cycles, and plumage changes in chihi are presented as a step toward clarifying the relationship of these two puzzling forms of ibis; but the full significance of these findings cannot be ascertained until more is known about the habits of falcinellus. The most important conclusions concern plumage changes. It is shown that published descriptions of plumage and molt in chihl …

Chemosynthetic Microorganisms In Leaching Sulfide Minerals, A. Keith Jameson

Theses and Dissertations

This investigation showed that a single bacterium was capable of sulfide oxidation in exposed ore bodies. This single bacterium was isolated and characterized. It exhibited different characteristics than any previously known organism. It was found to be a chemosynthetic autotroph. An optimum nutrient concentration was determined for pyrite oxidation. The nutrient concentration was determined for pyrite oxidation. The nutrient contains only a source of phosphate and nitrogen. Urea was found to be a better source of nitrogen than ammonium sulfate which had previously been used. The effect of various organic compounds on the oxidation of pyrite was observed. Glucose and …

Rat And Mouse Control On The Farm, John A. Lofgren

SDSU Extension Circulars

Each year the Norway ( or brown) rat and the common house mouse consume thousands of bushels of grain and other foods on South Dakota farms. They attack grain in the field and in farm storage. At the time they consume the grain they also pollute and contaminate it by their droppings, urine and hair. Every 24 hours each rat voids an average of 70 pellets and about 15 cc of urine. Such contamination makes food grains subject to seizure by the Food and Drug Administration because they are unfit for human use. The monetary losses resulting from such seizure …

The Occurrence Of Echinococcus Multilocularis Leuckart, 1863, In Japan, Robert L. Rausch, Jiro Yamashita

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Since 1937, when alveolar hydatid disease was first recognized on the Japanese island of Rebun, 25 cases have been investigated clinically. About one percent of the population of the island is believed to be infected. (Yamashita et al., 1955). Five cases also have been reported from other islands, some of these involving emigrants from Rebun (Inukai et al., 1955; Yamashita, 1956).

The Effects Of Desoxycorticosterone Trimethylacetate, Desoxycorticosterone Acetate, Cortisone Acetate, And Adrenalectomy On The Liver Succinoxidase And Glutamic Dehydrogenase Activity Of Rats Fed 3'-Methyl-4-Dimethylaminoazobenzene (3'-Me-Dab), John P. Davanzo

Biology ETDs

Experimental production of liver cancer by means of azo dyes is a standardized and convenient method for study of the cancer problem. The rat is the animal of choice for this type of experimentation because this animal is readily susceptible to liver carcinogenesis upon being fed azo dyes. Mice are only partially susceptible and rabbits and guinea pigs will not develop cancer of the liver by ingestion of the azo dyes (E. C. Miller and J. A. Miller, 1947, p.473). The liver, likewise, is an appropriate organ for study. Enzymologists and cytologists today regard the liver cell as the best …

Synthetic Polymers In Coating Colors: The Adhesive Values Of Lattices And Their Effects On Properties Of Laboratory Coated Papers, Shwang Hsia

Paper Engineering Senior Theses

Five synthetic latices have been evaluated as to their adhesive values and influence on optical properties of the coated papers.

The five synthetic polymers were acrylates, acrylonitrile-buta-diene, polyethylene, polystyrene-butadiene, and vinyl acetate.

The latices were used to substitute, on a pound per pound basis, 25, 50 and 75 percent of the casein used as binder in a standard coating color consisting of 100 parts of coating clay and 16 parts of casein.

Higher adhesive values than that of straight casein were established by acrylates and two butadiene copolymers. Vinyl acetate and polyethylene possessed lower adhesive values than straight casein color. …

Utilization Of Surplus Milk In The Small Dairy Plant: 2. Soft And Semi-Soft Hoop Drained Cheeses, P. A. Downs

Nebraska Agricultural Experiment Station: Historical Circulars

The purpose of this series of publications is to describe how a variety of products may be prepared in plants to more profitably utilize milk. Each type of product is described in detail, methods of manufacturing outlined, and the equipment and supplies needed are listed. As far as possible similar equipment can be used for several products. In this publication the preparation of a group of cheeses of the soft and semi-soft hoop drained type is presented.

Bear Lake It's Fish And Fishing, William J. Mcconnell, William J. Clark, William F. Sigler

Watershed Sciences Faculty Publications

Bear Lake is an old lake. The lake basin was form ed during the growth of the surround ing mountains; since that time, a lake has been present whenever the climate has been wet enough, but it has probably completely dried up during very dry periods.

The Incidence Of Nasal Mites In Over-Wintering Red-Wing Blackbirds In The Vicinity Of Utah Lake, Utah, George M. Talley

Theses and Dissertations

This paper reports the incidence and associations of four species of mites, Paraneonyssus icteridius, Ptilonyssus n. sp. "A", Sternostoma n. sp. "A" , and Speleognathus sp., found in the nasal cavities of the common red-wing blackbird (Agelaius phoeniceus ssp.) and Brewer's blackbird (Euphagus cyanocephalus cyanocephalus Wagler) over-wintering in the vicinity of Provo, Utah County, Utah. Three species of mites are reported for the first time from these birds, and two of these three are undescribed species.

The Embryology Of The Paradise Fish, Macropodus Opercularis Linnaeus, Lewis M. Mulkay

Theses and Dissertations

The development of Sacropodus opercularis Linnaeus, (Perciformes: Anabantidae), is described from cleavage to five days post hatching. For the most part M. opercularis follows the pattern of typical teleostean development except as noted below: 1. The heart develops under the left eye along the anterior margin of the yolk sac. This is similar to that reported by Ingesoll (1951) for the Blue Gourami, Trichogaster trichopterus. 2. The ear develps from the head mesenchyme alongside the brain rather than from a placode. 3. The gut develops first in the posterior region then differentiates cephalad. It was also learned that: 1. No …
