New Computer Methods For Protein Crystallography, Martin Zwick

Complex Systems Faculty Publications and Presentations

New Computer Methods for Protein Crystallography, by Martin Zwick. Submitted to the Department of Biology on 30 August 1968 in partial fulfillment of the requirements for the degree of Doctor of Philosophy. The section, "MYOGLOBIN REFINEMENT," describes the fitting of an idealized polypeptide chain to a set of approximate backbone coordinates for the protein, sperm whale myoglobin. This procedure refines the structure by imposing upon it known bond distances and angles, and simultaneously derives a representation of the polypeptide conformation in terms of the values of the rotation angles about its single bonds. The overall rms and mean deviation between …

Colonial Independence Of Feeding Among Zooids Of The Ectoproct Lophodella Carteri (Hyatt), Leonard M. Bahr

Master's Theses

Possible interactions of feeding between zooids of colonies of the freshwater ectoproct Lophopodella carter! were investigated. Suspensions of Euglena gracilis at a concentration of 558x10³ cells ml^-1 were cleared by L. carter at a rate of 2.7 x 10^-3 ml min^-1 zooid^-1 for15 minute periods. The rate of ingestion of E. gracilis by L. carter was independent of the size of colony and decreased exponentially with time, declining to about one third the original rate in 60 minutes.

Concurrent Infections Of Schistosoma Mansoni And Trypanosoma Equiperdum In Mice, Venus Ee-Siriporn

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this investigation was to determine factors which may influence the survival time of mice infected with Trypanosoma equiperdum and the effects of T. equiperdum on mice infected with Schistosoma mansoni.

In order to maintain experimentally obtained standard hours of survival (88 hrs) in mice inoculated intraperitoneally with 150,000 T. equiperdum, it was found that trypanosomes removed from the donor rat should be kept at 25 C and all counts, dilutions of the organisms, and injection should be completed within 1 hour after removal from the donor host. Survival time of mice is increased as the …

A Study Of Alveolar Bone Loss And Two-Hour Postprandial Blood Sugar Levels, R. Leslie Arnett

Loma Linda University Electronic Theses, Dissertations & Projects

Two-hour postprandial blood sugar determinations were carried out on 500 patients referred for periodontal care. The mean percentage of alveolar bone loss around the mandibular bicuspid teeth was established for each individual. The subjects were then grouped according to blood sugar levels and the mean alveolar bone loss was calculated. The group was separated into male and female sub-groups and data was computed for these segments as well as the total sample. The data was evaluated in a similar manner for those subjects between 40 and 49 years of age.

No Chi-square determinations were statistically significant but significance in differences …

Isolation And Partial Characterization Of The Toxic Substance From Eremocarpus Setigerus Benth, Shuliang Lee

Loma Linda University Electronic Theses, Dissertations & Projects

The work on the active substance of Eremocarpus setigerus Benth has been previously performed by Naito and Noller. However, the investigation was not complete. Therefore we isolated and tested this substance by steam distillation and thin layer chromatography technique. A yellow sticky toxic substance was isolated with Rf values of 0.15 in benzene system and 0.57 in benzene-absolute ethanol (95:5 v/v) system.

The toxic substance which is free of halogen, nitrogen, and sulfur, is soluble in ethyl ether, ethanol, and concentrated sulfuric acid. It has a maximum absorption in the ultraviolet region that indicates the presence of unsaturation. Its infrared …

Linear Programming Applied To Sheep Ranching In Utah, William R. Flint

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The study was initiated to determine how sheep ranches were physically and economically organized in 1964 and to select range and livestock management alternatives which would be profitable to sheep ranches. With data collected from the ranches three model ranches, representing the three most prominent strata, were constructed. These strata were determined by number of breeding ewes that were on the ranch and by the season of grazing on government land, i.e., winter, summer, or year around. After the building of these three ranches, each of them was linear programmed to find the profit maximizing combination of resources both before …

An Experimental Study Of Variation Within And Between Populations Of Petrophytum Caespitosum (Nutt.) Rydb. With Emphasis On Numerical Techniques, Frank R. Drysdale

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

(Rosaceae) in the Intermountain Region were investigated for taxonomically significant variation using numerical techniques. On the basis of 19 morphological characters 3 subspecific taxa are recognized. Two taxa are existing subspecies: P. caespitosum (Nutt.) Rydb. var. caespitosum and P. caespitosum (Nutt.) Rydb. var. elatius (S. Wats.) Tides. One new subspecies is described: P. caespitosum (Nutt.) Rydb. var. latifolium. The ecology of the species is discussed. The floral and vegetative anatomy are described. Chromosome counts of 3 populations have given n = 9. A list of herbarium …

Systemic Studies Of The Genus Gila (Cyprinidae) Of The Colorado River Basin, Paul Bernard Holden

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Three Hundred and nine specimens of Gila from the Colorado River basin were studied. A form of numerical taxonomy, taximetrics, was used to help classify the specimens. The data from these fish indicate that many of the present hypotheses concerning their taxonomy are not valid. The concept of ecosubspecies or ecological subspecies does not fit the Colorado basin Gila. The roundtail and bonytail chubs, G. robusta Baird and Girard and G. elegans Baird and Girard respectively, currently treated as subspecies, are well separated morphologically, ecologically and reproductively and therefore are better considered two valid species. The relationship between G. …

Target Markets For Directing Utah Summer Tourism Promotion And Information, Perry J. Brown

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The characteristics of tourists visiting Utah that are pertinent to defining target markets for the direction of state promotion programs were studied and analyzed during the summer of 1966.

Five significant geographical-party composition target markets were identified as prospective tourist markets. These were California families, East-West North Central families, Western families, East-West North Central couples, and California couples.

Target markets of enroute tourist parties were also identified for instate promotional efforts. The markets identified were divided on their relative degree of vacation planning and willingness to deviate from a planned route to visit additional attractions.

Significant differences among parties found …

Estimated Supply Response Of Sugar Beet Production To Changes In Profitableness, Box Elder And Cache Counties, Utah, 1967, Brent W. Spaulding

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The relative profitability of sugar beets and competitive crops were studied in Box Elder and Cache counties, Utah.

Profitability ratios based on enterprise budget data and resource use requirements were used as a basis for comparison. Sugar beets was found to be more profitable than competing crops in returns per acre, in returns to water used and in returns to fixed investment and management. However, sugar beets was found to be less profitable than certain other crops in returns to operating capital and returns to labor. Also, on land rated low in productivity sugar beets was found to be less …

The Value Of A Trout Stream Fishery, Archie Allen Dyer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The data analysis indicated that travel distance, user age, and user income level are important determinants of use of trout streams.

These variables were incorporated into regression analysis to develop a use-prediction model.

This use-prediction model was used to determine predicted use levels of sample streams. The predicted use levels combined with travel costs and expenditures on new fishing equipment were used to derive a statistical estimate of the demand schedules for the sample streams.

These statistical demand curves were subjected to consumer surplus procedures to determine the values of the sample streams.

Distributional Changes And Interaction Between Prairie Chickens And Sharp-Tailed Grouse In The Midwest, Paul A. Johnsgard, Robert E. Wood

Papers in Ornithology

The "prairie grouse" of North America present an interesting example of the effects of human activities on breeding distribution patterns of birds, with resulting changes in geographic distribution and spacial isolation. Thus, the Heath Hen (Tympanuchus cupido cupido) was one of the most familiar birds to the early colonists, who relied heavily on it for food. Ultimately, loss of habitat caused the Heath Hen's extinction. When the vast tall-grass prairies west of the Appalachians were settled, Greater Prairie Chickens (T. c. pinnatus) were probably more plentiful, and greatly increased as woods were cleared and grain crops supplemented native grasses. With …
