A Redescription Of Taenia Taxidiensis Skinker, 1935, Robert Rausch Jan 1947

A Redescription Of Taenia Taxidiensis Skinker, 1935, Robert Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Since the original description of Taenia taxidiensis Skinker, 1935,2 was based on an incomplete and apparently immature cestode, a redescription seems desirable.

The following description is based on 28 cestodes, taken from three infected badgers, Taxidea taxus (Schreber), all collected in southern Wisconsin. Of these, only one strobila had gravid segments, the others being immature. Most of the data given below are based on the single mature specimen, with additional measurements, where Possible, from the immature worms. No sections were made of these specimens, and the measurements given were taken fl·om stained wholemounts.

Contributions To The Study On Helminth Fauna Of Dillon Beach, Francis C. Gale Jan 1947

Contributions To The Study On Helminth Fauna Of Dillon Beach, Francis C. Gale

University of the Pacific Theses and Dissertations

Studies on trematodes of marine organisms of the Pacific Coast have been of a scattered and fragmentary nature. J. Stafford (1904) collected and described a number of trematodes from fishes of the north Pacific, but, in his historical survey, Manter (1926) fails to mention specifically any studies covering the waters south of Canada. More recently, in the United States, several contributions to the field have been made by Dr. John E. Guberlet at the University of Washington and at the College of the Pacific by Dr. Alden Noble, under whose guidance this study was made. James Park (1937) revised the …


A Survey Of Intestinal Protozoa At The Stockton State Hospital : Stockton, California, Lawrence Melvin Gholz Jan 1947

A Survey Of Intestinal Protozoa At The Stockton State Hospital : Stockton, California, Lawrence Melvin Gholz

University of the Pacific Theses and Dissertations

During the past months much has been published in periodicals, especially those of a pictorial nature, which discredits institutions established for the care of' the mentally ill throughout the nation. Many articles have been presented which show an intelligent approach, but the majority of these treatments are by those who are basing too much on a very narrow experience. For example, one news magazine recently printed a picture of a mental patient in institutional garb sitting on a bench in one of the poses most characteristic of a catatonic. The caption of the picture seemed to ignore this significant fact …


Bulletin No. 326 - Rainfall And Irrigation In Relation To Soil Erosion, Willard Gardner, John Hale Gardner, C. W. Lauritzen Dec 1946

Bulletin No. 326 - Rainfall And Irrigation In Relation To Soil Erosion, Willard Gardner, John Hale Gardner, C. W. Lauritzen

UAES Bulletins

This paper attempts to point out to farmers, agricultural specialists, and others who may be interested, pertinent facts regarding rainfall intensity and other meteorological data that have to do with the wearing down of range and agricultural soils, and to present by means of diagrams illustrations of general relationships between the rate of wearing down of irrigated soils, the size of the irrigation stream and the slope of the eroding surface.

Large streams running down steep slopes, whether from rainfall or from irrigation, constitute a destructive process that cannot be completely controlled. Fortunately, vegetation protects the soil against the destructive …


The Nebraska Egg Cooler, I. L. Williams, F. E. Mussehl Dec 1946

The Nebraska Egg Cooler, I. L. Williams, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Circulars

Every producer knows that heat is harmful to the quality of eggs, and that the first step in holding fine egg quality is prompt removal of the animal heat. The Nebraska egg cooler has been developed for this purpose. Construction costs are moderate, and repeated observations demonstrate the effectiveness of the principle. Its basic factor is the temperature-reducing effect of cool, humid air passing over the eggs, as soon as possible after they are gathered.

The Geologic History Of The Bison In The Great Plains (A Preliminary Report), C. Bertrand Schultz, W. D. Frankforter Dec 1946

The Geologic History Of The Bison In The Great Plains (A Preliminary Report), C. Bertrand Schultz, W. D. Frankforter

Bulletin of the University of Nebraska State Museum (1924–2023)

THE GEOLOGIC history of the bison in North America is a subject which has received little attention to date. Osteological rather than geological problems have been the main concern of most writers who have so far published. If the geologic history of the bison is to be learned, it will be necessary to devote more time and effort in the field in determining the age of the deposits in which various specimens have been discovered and in making more extensive collections from deposits of known age. Unfortunately the majority of the type specimens have been surface finds and little attempt …


Fusarium Conglutinens Variety Callistephi, Beach And Its Effect On The Chrysanthemum, Mary Heimick Palmer Dec 1946

Fusarium Conglutinens Variety Callistephi, Beach And Its Effect On The Chrysanthemum, Mary Heimick Palmer

Bachelors’ Theses

This thesis is the result of extensive research for the past year at Marquette University on Chrysanthemums. In particular, I refer to a specific problem, that of an attempt to ascertain with certainty the cause of a serious infection of Chrysanthemums. This treatise covers the procedure and methods used in discovering the actual pathogen, and my reasons for believing that this particular pathogen is Fusarium conglutinens variety Callistephi.


The Effects Of Estrogens On The Thyroid & Adrenal Glands Of The Male Turtle, Jeanne Frances Genrich Dec 1946

The Effects Of Estrogens On The Thyroid & Adrenal Glands Of The Male Turtle, Jeanne Frances Genrich

Bachelors’ Theses

Up to the present time there appears to have been very little research done on the thyroid or adrenal glands of the turtle. This seems to be especially true in respect to the effects of estrogens on these two glands. However, some work has been reported on other members of the reptilian family; particularly garter snakes, and more recently, the lizard.

Bake Bread Successfully, Anna M. Wilson Oct 1946

Bake Bread Successfully, Anna M. Wilson

SDSU Extension Circulars

During the latter spring and summer months of 1946 the United States was able to send more wheat abroad to starving people because we use 80 percent extraction flour instead of the customary 72 percent. Using 80 percent extraction flour taught us that degree of refinement does make a difference in the way flour must be handled in making yeast bread. In this circular we shall learn why wheat means so much to a world harassed with famine and how we can make better use of wheat by understanding the principals involved in breadmaking.

Pollination Cycles And Pollen Dispersal In Relation To Grass Improvement, Melvin D. Jones, L. C. Newell Oct 1946

Pollination Cycles And Pollen Dispersal In Relation To Grass Improvement, Melvin D. Jones, L. C. Newell

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The plant breeder is initially concerned with gaining a knowledge of the breeding behavior of his plant materials in order that improvement may be undertaken effectively. It is important to know the different characteristic pollination habits of these plants. To develop and apply techniques applicable to the improvement of a given grass crop, it is desirable to know the time of day and the number of days that the grass sheds pollen. The effects of temperature, humidity, light, and wind on pollination must be considered. Once superiority of germplasm is obtained, the most important consideration is the maintenance of this …

The Rh Factor: Recent Developments And A Study Of Its Incidence Among The Indians Of The Southwest, Earl B. Gerheim Aug 1946

The Rh Factor: Recent Developments And A Study Of Its Incidence Among The Indians Of The Southwest, Earl B. Gerheim

Biology ETDs

The purpose of this study was to continue the work started in determining the incidence of the Rh factor among Indians of the Southwest and review the related literature. This paper will include the author's initial results in which 251 Indians were tested.

There is at this time no published account on the incidence of the Rh factor among the Indians of the Southwest; therefore, this is important from the standpoint of originality. The problem has medical importance in the role which Rh plays in transfusion and congenital hemolytic disease, otherwise known as erythroblastosis fetalis. The results will serve as …


Pig Typhus (Salmonellosis Suis), L. Van Es Aug 1946

Pig Typhus (Salmonellosis Suis), L. Van Es

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Salmonellosis suis or pig typhus, also designated as pig typhoid, infectious necrotic enteritis, or "necro," is an infectious disease among young pigs. It constitutes a major factor in the mortality of juvenile swine, and as such must be regarded as a more or less perennial hazard in swine production. Infectious necrotic enteritis caused by Salmonella suipestifer is the subject of the present publication.


Bulletin No. 325 - An Economic Study Of Sheep Production In Southwestern Utah, Dee A. Broadbent, George T. Blanch, W. Preston Thomas Aug 1946

Bulletin No. 325 - An Economic Study Of Sheep Production In Southwestern Utah, Dee A. Broadbent, George T. Blanch, W. Preston Thomas

UAES Bulletins

Range sheep production has been one of the major agricultural enterprises in Utah, particularly in the southwestern part of the state, since these areas were first settled. Stock sheep numbers in Utah were about 2,100,000 by 1890, which is approximately the present number in the state. Since 1890 the numbers have fluctuated between 2,000,000 and 2,775,000.

This important industry has, from the time of its introduction, been closely associated with the use of public range lands. The unrestricted grazing of public range lands resulted in damage to a considerable area and was one of the important factors that led to …


Vitamins For Poultry, F. E. Mussehl, C. W. Ackerson Aug 1946

Vitamins For Poultry, F. E. Mussehl, C. W. Ackerson

Nebraska Agricultural Experiment Station: Historical Circulars

Vitamins are chemical substances essential for the maintenance of life, growth, and reproduction. Their effects are out of proportion to the relatively small amounts required. Fortunately, most of these essentials are widely distributed in nature, and an adequate ration can nearly always be provided by using logical combinations of common feedstuffs. Under certain conditions, however, the use of vitamin-containing concentrates may be desirable. In planning practical rations, it should be recognized that the plant leaf is the source of most vitamins. Milk and meat products make important vitamin contributions to the diet in addition to their proteins and minerals. Direct …

A Cytological Study Of The Salivary Gland Chromosomes Of The Attached-X Variety Of Drosophila Melanogaster, Jack Schull Aug 1946

A Cytological Study Of The Salivary Gland Chromosomes Of The Attached-X Variety Of Drosophila Melanogaster, Jack Schull

Bachelors’ Theses

The detailed study of -the salivary chromosomes of the Diptera has been of great importance in substantiating cytologically the theories of genetics. A noteworthy example of the importance of cytological study is the non-disjunctive phenomenon which has occurred on at least several occasions in the strain of Drosophila melanogaster. Bridges (1913) was the first to report nondisjunction of sex chromosomes which was an important confirmation of the chromosome theory. L. V. Morgan (1922) used the cytological study of the germ cells of Drosophila melanogaster to prove that there was no disjunction of the sex chromosomes in the attached-X strain.


A Comparison Of The Autonomic Nervous System Of The Cat And The Pigeon, William P. Mccarthy Aug 1946

A Comparison Of The Autonomic Nervous System Of The Cat And The Pigeon, William P. Mccarthy

Bachelors’ Theses

The purpose of this thesis is to describe the autonomic nervous system of the cat and pigeon and to compare them as to their structure. This comparison will consist in noting the differences and points of similarity between the two animals. The autonomic nervous system of the cat is more complex than that of the pigeon and for that reason the comparison will consist in pointing out the parts of the autonomic nervous system present in the cat, but which are not found in the pigeon. In noting the points of similarity only the most important will be treated.
