Multiple Cropping Will Increase The Erosion Hazard, W J. Burdass

Journal of the Department of Agriculture, Western Australia, Series 4

WITH the low price of wool and the price of wheat high in comparison, farmers need little encouragement to increase their acreage of crops.

Unfortunately with increased cropping comes the risk of increased erosion—unless there is a simultaneous increase in the use of conservation practices.

The Relationship Of Church Activity Of Parents Of Lds Seminary Students To The Attendance Of Seminary Students At Church, Ronald D. Firth

Theses and Dissertations

It has been observed that not all L.D.S. Seminary students are active in church attendance. There is little doubt in the minds of educators that parents affect a great deal the activities of their children.

The purpose of the study was to learn what relationship, if any, existed between a seminary student's church attendance and the church activities of his parents, and to find out which, if any, of five specific areas of parental church activity had the most positive effect on a student's church attendance.

Based on his experience in the church, the writer chose the following areas of …

Urban Geology—A Need And A Challenge, William J. Wayne

Department of Earth and Atmospheric Sciences: Faculty Publications

Urban land uses are rapidly converting open land into intensively used land. Generally, in planning those uses, a comprehensive study has included everything except an evaluation of the land in three dimensions. Geologists are eminently well equipped to supply the missing data, but they must also be aware of the needs of the urban community and the kinds of information needed by planners if they are to write reports usable by planners. Urban and environmental geology is a newly expanding field in the use of geologic data to help solve some urban problems in the planning stage. It is likely …

Mechanical Effects Of Acoustic Transients On Tobacco Mosaic Virus, Philip Edward Hamrick

Theses and Dissertations

The mechanical breakage of tobacco mosaic virus (TMV) due to the action of acoustic transients has been investigated. The acoustic transients were produced by transient heating of a Prussian blue dye solution (attenuation coefficient of 1000 per cm) when a ruby laser light (20 x 10⁶ watts) was incident on the dye surface. A quartz piezoelectric transducer was used to determine the amplitude and form of the acoustic wave. The production of acoustic waves by transient heating is discussed, and the theoretical form of the acoustic wave determined for various boundary and initial conditions are compared to the experimentally …

A Study Of The Removal Of Pesticides From Water, James David Whitehouse

KWRRI Research Reports

The purpose of this study was to investigate some of the properties of pesticides as they exist in water, and to determine the effectiveness of several water treatment processes in the removal of pesticides from water. Among the pesticides investigated were malathion, DDT, aldrin, dieldrin, captan, benzene hexachloride (BHC), 2,4-D, and 2,4,5-T. The water treatment processes included aeration, chemical coagulation, adsorption on activated carbons and clays, and foam separation.

The removal of pesticides from water by aeration was found to be significant. Dieldrin was removed almost 100 percent, while aldrin, DDT, and BHC were removed to a lesser extent. 2, …

Water Quality Study Of Lake Mead, Dale A. Hoffman, Paul R. Tramutt, Frank C. Heller, Bureau Of Reclamation

Publications (WR)

This report presents Lake Mead Water quality data obtained from 1964 to 1966. The effect of filling Lake Powell on the water quality of Lake Mead is evaluated. General limnological principles and the present limnology of Lake Mead are discussed. Lake Mead has a warm monomictic annual temperature cycle characterized by summer stratification, fall overturn leading into a continuous circulation throughout the winter; temperatures never fall below 39 deg F (4 deg C). During stratification, lower dissolved oxygen values were recorded in the thermocline than in the epilimnion and hypolimnion. Mineral content increases from the upper to the lower end …

Problems Encountered With Control Networks In Highly-Restructurable Digital Systems, Donald F. Wann, Robert A. Ellis, Mishell J. Stucki, Robert M. Keller

All HMC Faculty Publications and Research

This paper discusses problems encountered with control networks in highly restructurable digital systems. In particular the treatment of implementation errors is covered with emphasis on concurrent processing. The implementation of concurrent processing networks may result in errors which will be quite complex to detect and systematic methods are warranted. Four meta control elements are employed in obtaining convenient concurrent structures. We analyze several error detecting schemes and conclude that the arc-node method with node partitioning appears to be the most realistic approach at this time.

Nurse-Patient Interpretations Of The Nurse's Touch, Judith Ann Trowbridge

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to discover whether or not patients and nurses derived a similar meaning from pictures of a nurse touching a patient in various ways. Five by seven inch black and white photographs were shown to thirty patients and thirty registered nurses. The subjects were controlled in regard to sex, race, residence, language, and physical and emotional orientation. They were asked to focus upon the photographed nurse's touch and to tell in one or two words what meaning they felt that the nurse was trying to convey to the patient by her touch. Responses were recorded …

The Effects Of Particular Sounds On Certain Indices Of Cardio-Pulmonary Functions, Harold F. Googe, Jane Mundin

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to identify the effects of particular sounds upon certain indices of cardio-pulmonary function and the degree and pattern of changes which occurred in the indices. The specific physiological parameters chosen to be monitored were heart rate, respiratory rate, mean tidal volume, instantaneous minute volume, and oxygen consumption. The hypothesis was that particular sounds will cause changes in certain indices of cardio-pulmonary functions. This was a controlled experiment, in which nine healthy males and nine healthy females, of a denominational, medically oriented University listened to a specially constructed tape of background music interspersed with an …

Secondary Reactions And Partial Rate Factors In The Sulfonation Of Chlorobenzene And Toluene, Ernest Arthur Brown

Theses and Dissertations

The sulfonation of chlorobenzene, chlorobenzene-benzene, and toluene-benzene mixtures by sulfur trioxide in liquid sulfur dioxide at -12.5° C. was studied to obtain isomer distribution and relative rate data. The isomer distribution for the reaction on chlorobenzene was determined by an isotope dillution technique. Relative rate experiments were conducted by sulfonating C14 labeled benzene in competition with nonradioactive chlorobenzene and toluene and the count rate of the products was used to determine product composition. Ultraviolet spectrophotometry was also used to investigate variations in isomer distributions as a function of sulfur trioxide concentration. The apparent relative rates of sulfonation (kX/kB) as calculated …

A total of 223 cephalometric radiographs selected from six contemporary western United States and Alaskans native groups were analyzed by use of the Bjork cephalometric analysis. Those native groups selected were the Eskimos, Apaches, Navajos, Papagos, Pimas and Mayos. Approximately thirty to forty natives from each group were used in the study with ages ranging from thirteen to thirty-five years. The majority were in the fifteen to twenty year age range.

All data was submitted to various statistical analyses to establish a mean, standard deviation, and other relevant values for each of the native groups and to compare these values …

An Odontometric Study Of Five Contemporary Western United States Indian And Alaskan Eskimo Groups, John A. Matis

Loma Linda University Electronic Theses, Dissertations & Projects

The morphologic characteristics of the oral cavity in five contemporary Western Indian and Alaskan Eskimo groups have been investigated by the use of study models of the dental archs. The sample consisted of 216 individuals, including 44 Navajos, 43 Apaches, 40 Papagos, 42 Pimas and 47 Alaskan Eskimos.

The first purpose of the study was to determine the extent of investigator error. This was accomplished by remeasuring many morphologic traits of the dentition in 125 Indians which had previously been measured by different investigators using the same study models. It was found that investigator error can be significant, even in …

Aircraft As A Means Of Baiting Ground Squirrels, Rex E. Marsh

Vertebrate Pest Conference Proceedings: 3rd (1967)

Aircraft might soon become an important tool for baiting ground squirrels (Citellus beecheyi beecheyi and C. b. fisheri) on California rangeland. Until recently, almost all squirrel control has been conducted by the hand-baiting method, with grain bait scattered from horseback in spoon-size amounts near squirrel burrows. Ground squirrels are considered a major pest of rangeland in many parts of the West. They not only compete with livestock for forage but also are responsible for substantial losses to cereal and other crops. The magnitude of the problem is exemplified by the fact that, in California alone, over 6,000,000 gross acres of …
