A Survey Of The Breakfast And Snack Habits Of Adventist And Non-Adventist Adolescents, Consuelo A. Bustista

Loma Linda University Electronic Theses, Dissertations & Projects

A study was undertaken to survey by questionnaire and interview methods the breakfast and snack habits of Adventist and non-Adventist adolescents. The purposes of the study were: (I) to find out if there is any difference in the practices of Adventist and non-Adventist teenagers, and (2) to determine their attitudes toward snacking and omission of breakfast.

Results of the questionnaire were coded, punched onto IBM cards, and fed into computing machines for item and statistical analysis. Chi-square test analyses were done on denominational classification against some questions of interest to show any significant differences between Adventist and non-Adventist students' responses. …

A Study Of The Effects Of Dredging And Dredge Spoil Disposal On The Marine Environment: Project Report., Virginia Institute Of Marine Science

Reports

The Rappahannock Shoal and spoil disposal area investigated encompasses an area of approximately 180 square miles. The initial sampling program (1961) consisted of the establishment of a series of transects across the survey area. One hundred sampling stations were located along the established transects.

Inasmuch as the texture of the bottom sediments varied distinctly from place to place within the mid-bay region, the initial objective was to delineate the sediment distribution. Ninety-eight core samples were taken from the area with a modified Phleger coring device and analyzed in detail for textural characteristics. Representative stations were chosen and core samples were …

Citellus Kimballensis, A New Late Pliocene Ground Squirrel, Douglas C. Kent

Bulletin of the University of Nebraska State Museum

A new fossil sciurid, Citellus kimballensis, is described. This new species was found in the Kimball Formation, uppermost Ogallala (very late Pliocene) at the University of Nebraska State Museum Collecting Locality Cn-1O1, northeast of Sidney, Cheyenne County, Nebraska. Characters of the dentition and skull of C. kimballensis are compared with those of other species of the genus, and with those of Cynomys.

The Effects Of Shearing Time And Stocking Rate On Wool Production, R J. Lightfoot

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

THE results of the first experiment comparing "autumn" versus "spring" shearing over a two-year period were published in 1960.

In this experiment the autumn-shorn ewes cut heavier greasy fleeces (even though they also reared considerably more lambs) with less tender wool, resulting in a higher average return per head from this group.

The autumn-shorn wool carried more seed, was less attractive and contained relatively more pieces than did the spring-shorn wool.

The Monotypic North American Subgenus Larandrena Of Andrena (Hymenoptera: Apoidea), D. W. Ribble

Bulletin of the University of Nebraska State Museum

Larandrena contains a single species, A. miserabilis Cresson. This small, common Andrena is found throughout most of the United States and southern Canada in the spring. The subgeneric position, nomenclature, redescription. variation, notes on the biology, parasites, range, seasonal activity and plant host records are included. A. rniserabilis is thought to be an important pollinator of fruit trees.

A New Species Of Rhinoceros, Aphelops Kimballensis, From The Latest Pliocene Of Nebraska, Lloyd G. Tanner

Bulletin of the University of Nebraska State Museum

An uncrushed skull and associated skeletal elements of a very large rhinoceros are the basis for the description of a new species of Aphelops from Frontier County, Nebraska. The major differences are: the skull is much larger in most dimensions than other Aphelops; it has an extremely elevated occipital region in comparison to Aphelops mutilus; the narial notch is retracted to a point perpendicular to the center of molar one; and the teeth are more hypsodont than any other species of this genus. The sediments which yielded the skull and skeletal parts are considered to be Kimballian in …

Intertidal Zonation Of Marine Algae At Gloucester Point, Virginia, Barry Lee Wulff

Dissertations, Theses, and Masters Projects

A study was made of the intertidal zone of aged wooden pilings from February to June, 1967 at Gloucester Point Virginia,located in the lower York River estuary. Twenty-six species of marine algae were found grouped into three floristic zones.

Nine species were limited to below mean low water, whichialL.rlted the lowest cone. In this group there were six Rhodophyta and three Chlorophyta. Seven floral levels comprised the middle floristic zone between mean low water to a height of 74 cm above mean low water. These levels ere based on uppermost range extensions of sixteen species (six Cyanophyta, two Rhodophyta,one Phaeophyta …

A Revision Of The Bees Of The Genus Andrena Of The Western Hemisphere. Part I. Callandrena. (Hymenoptera: Andrenidae), Wallace E. Laberge

Bulletin of the University of Nebraska State Museum

This paper is the first part of a monograph of the bee genus Andrena in the western hemisphere and treats the subgenus Callandrena. Available data regarding phylogeny, distribution, biology, and flower preferences are presented together with keys to separate the species, diagnoses and descriptions of the species and discussions of geographic variation when applicable. Seventy-nine species and one subspecies are recognized. Sixteen names are relegated to synonymy, one to homonymy and eight are removed from the subgenus Callandrena. The thirty-nine species new to science are: aerifera, aeripes, afimbriata, ardis, auripes, balsamorhizae, beameri, bilimeki, bullata, calvata, dreisbachorum, fulminea, fulminoides, …

The Brule-Gering (Oligocene-Miocene) Contact In The Wildcat Ridge Area Of Western Nebraska, C. Bertrand Schultz, Charles H. Falkenbach, Carl F. Vondra

Bulletin of the University of Nebraska State Museum

The contact between the Brule Formation (Oligocene) and the Gering Formation (Miocene) can be readily distinguished in the Wildcat Ridge area, as elsewhere in western Nebraska. At the critical fossiliferous exposures at Castle Rock in Scotts Bluff County, the contact on the south face between the two formations is defined as 129 feet above the base of the "Upper Ash" bed, which corresponds to the upper portion of Darton's (1899, PI. C, Fig. D, following p. 754) "sandy phase" in the upper part of the Brule. Certain key beds in the Gering Formation can be traced laterally from a channel …

Phalaris Staggers : Prevention By Cobalt Bullets, Bryan J. Gorddard, P. P. Mann, A. J. Hadlow

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

FARMERS in the south west of Western Australia are familiar with the use of cobalt for the prevention of ill-thrift and deaths due to cobalt deficiency in sheep and cattle.

Less common is the use of cobalt for the prevention of chronic phalaris poisoning, known as phalaris staggers.

This condition is well known in eastern Australia, but only isolated cases have been recorded in W.A. no doubt due to the relatively small area sown to phalaris in this state.

Water Blooms, T E H Aplin

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

WHEN a body of water becomes discoloured with a super-abundance of free-floating, microscopic plant or, in rare cases, animal life, it is said to develop a "water bloom."

This article discusses some aspects of the appearance of water blooms, particularly those caused by algae, and with the effects that certain toxic algae have on livestock.

Concentration Of Suspended Radioactive Wastes Into Bottom Deposits., Dexter S. Haven

Reports

During recent years rapid advances in nuclear technology have increased the probability of accidental contamination of our coastal estuarine waters by several routes. The chances of such contamination appear remote, but in the event of a nuclear accident, it would be imperative to understand processes which will disperse or concentrate radioactive materials. In coastal waters the disposal or transport of radionuclides in concentrations exceeding the maximum permissible concentration is affected by tidal action and by the volume of inflowing fresh waters. During the period of transport by coastal or estuarine currents, physical and chemical forces will produce abiotic sedimentation. The …
