Impact Of Plains Pocket Gophers On Forage Production, Ronald M. Case, James L. Stubbendieck, Dale G. Luce
Impact Of Plains Pocket Gophers On Forage Production, Ronald M. Case, James L. Stubbendieck, Dale G. Luce
Great Plains Wildlife Damage Control Workshop Proceedings
The presence of pocket gophers on rangeland and farmland is highly visible due to the earth mounds which they build. The nuisance impact of their mounds and acknowledged long-term beneficial effects on soil (Laycock and Richardson 1975) result in a value which is debatable. The impact of various species of Thomomys on herbage production of rangelands has been widely reported (Fitch and Bentley 1949; Richens 1965; Turner 1969; Laycock and Richardson 1975; Alsager 1977). However, besides our studies in Nebraska, we could find no literature concerning the effect of Geomys on forage production and no literature concerning the effect of …

On 18 September 1974, a cloud cluster growing in the GATE [Global Atmospheric Research Program] ship array was examined using aircraft flying close to one another at different heights, the geostationary satellite SMS-1, and radar, rawinsonde and ship data, with a view to elucidating mechanisms of convection. In this paper we concentrate analysis on cloudy convection in the moist layer.
In and above southerly surface monsoon flow approaching the cluster, clouds indigenous to the moist layer took the form of rows of tiny cumulus, and of arcs of cumulus mediocris, with patterns different from those of deeper clouds. From satellite …

Analysis And Interpretation Of The 5,000 Ft (1,538 M) Red-Bed Sequence Encountered In The Sparks Et Al. #1-8 (Michigan Basin Deep Borehole), John H. Fowler
Masters Theses
A 5,000 ft (1,538 m) pre-Mt. Simon (Upper Cambrian) red-bed sequence, encountered in the Gratiot County deep borehole (Sparks et al. #1-8) and herein named the North Star Formation, consists of undeformed recurring beds of immature arkosic sandstone 2 to 34 in (5 to 85 cm) thick. These beds grade upward from erosional basal contacts into mudstone units 1 in to 12 ft (3 cm to 3.8 m) thick. Within the sandstones, grading, horizontal lamination, and crossstratification define Bouma intervals "a", "b", and "c", which combine to form incomplete Bouma sequences. Mudstones exhibit abundant horizontal laminations. Secondary sedimentary structures (load …

The Hanle Effect In Penning-Excited Ions, D. W. Fahey, William F. Parks, Laird D. Schearer
Physics Faculty Research & Creative Works
A thermal beam of helium (23S1) metastable atoms was used to excite coherently the 2P3/2 levels of Ca, Sr and Ba in a Penning ionizing collision. The coherent excitation of the ions appears as a linear polarization of the optical emission from the excited ions. The degree of linear polarization is 5.5, 3.5 and 0.5% for Ca, Sr and Ba, respectively, with the polarization parallel to the beam direction. Hanle effect signals from the 2P3/2 level of Sr were observed and the radioactive decay rate measured.

Conductive Strontium Titanate Layers Produced By Boron-Ion Implantation, Connie M. Cooper, P. S. Nayar, Edward Boyd Hale, Robert Gerson
Physics Faculty Research & Creative Works
The ion implantation of boron has been found to be an effective method for increasing the conductivity of strontium titanate. A highly conductive layer was formed by implantations at doses of 3.6x1016 to 1.0x1017 ions/cm2, using an accelerating voltage of 100 kV, corresponding to a boron range of about 300 nm. The conductivity of the implanted layer was found to be further enhanced by about four orders of magnitude after annealing at 225 °C. The surface resistivity attained was typically 1000 Ω/square at room temperature. The resistance increased with rising temperature between 77 and 500 K. All samples were found …

The Effects Of A Teen Mother Program On The Growth And Development Of The Child, Barbara Mccarthy
Loma Linda University Electronic Theses, Dissertations & Projects
Teen-aged childbearing is a serious social, economic and health problem which has now reached epidemic proportions in the United States. Teen pregnancies have been shown to produce infants of low birth weight, of higher risk to disease and of slower growth and development.
Many programs have been developed by the state and federal government to help the young mother better cope with the problems of pregnancy. These Teen Mother programs combine the opportunity to complete a high school education with instruction in the special skills needed for parenting. This study was designed to investigate the growth and development of the …

A Comparison Of The Empathy Of Registered Nurses Practicing Primary Nursing As Compared To That Of Registered Nurses Practicing Team Nursing, Carol Milardo Floriani
Loma Linda University Electronic Theses, Dissertations & Projects
Historically the most outstanding feature of the nursing profession has been its genuine concern for the human being, and quality care of the sick has been its manifestation. However, technology with its high level of development and pervasiveness in the culture of the United States has threatened not only our society at large but also the nursing profession. "Depersonalized" and "nursing" are contradictory terms, and if used together certainly cannot denote a high quality of nursing care. In order to meet this threat, concerned health care professionals are studying ways to increase the empathetic element in nursing care in order …

Bird Control Seminars Proceedings
DRC-1339 (3-chloro-4-methylbenzenamine HCI) is the active ingredient in Starlicide Complete, a commercial bait used to control starlings (Sturnus vulgaris) at animal feedlots throughout the U.S. Because of the recent widespread use of this product, par- ticularly within the wintering range of many raptors, they and other avian or mammalian scavenger or predator species may be exposed to large numbers of dead or dying star- lings and blackbirds (Icteridae) throughout the winter roosting season (November-March). Acute toxicity data are available for five species of raptors and a number of mammals indicating that DRC-1339 or its primary toxic metabolite DRC-2698 (N-(3-chloro-4-methylphenyl) acetamide, …
