African Rue (Peganum Harmala L.) In The United States, V. L. Cory

Field and Laboratory

Since its introduction into the United States, Peganum Harmala L. has become designated as "African rue" and by a few other names (probably none of them used for the species in its native area.) Although it does not belong to the rue family, but occurs in northern Africa, it also grows in western Asia near the Mediterranean Sea, and in south­eastern Europe.

Rejection: Some Causes, Symptoms, And Treatment, H. E. Andren

Medical Arts and Sciences: A Scientific Journal of the College of Medical Evangelists

One of the many causes of personality problems is the feeling of rejection. It may result in the individual's becoming hypersensitive, resentful, or demanding, particularly if this experience has occurred in the impressionable age of youth. It is my purpose in this paper to set forth some of the symptoms and responses that occur in the individual who has this feeling, and what avenues are open in the treatment of such maladjusted individuals.

Injurious Effects From Contacts With Millipedes, Bruce W. Halstead, Raymond Ryckman

Medical Arts and Sciences: A Scientific Journal of the College of Medical Evangelists

Millipedes are probably among the least mentioned of the so-called "medically important arthropods." Perusal of a number of the more common texts dealing with the entomological aspects of medicine (Belding, 1942: 600, Craig and Faust, 1940:511, Herms, 1946: 539, Mackie, Hunter, and Worth, 1945:515) revealed the concept, which is commonly believed, that millipedes are not capable of producing injurious effects. A recent experience of the senior author and additional investigation by both writers have prompted the writing of this paper in an effort to broaden scientific thinking regarding the medical significance of this animal.

A Study Of The Heel Flies, Hypodermia Lineatum Devillers And Hypoderma Novis Degeer, In South Dakota, John A. Lofgren

Electronic Theses and Dissertations

The heel flies or ox-warble flies and their larvae, commonly called cattle grubs or warbles, are among the most troublesome and costly insect pests of livestock producers in South Dakota. These parasites attack cattle almost exclusively although they may occur at times in other domestic and in wild animals. Infestations in man have been recorded, but these cases are quite rare. This work deals only with the occurrence of the parasites in cattle.

The Effect Of Age Of Gilt On Size Of Litter, Clifford Inman Iverson

Electronic Theses and Dissertations

Size of litter is an important consideration in determining the profits from a swine production enterprise. Basic information concerning factors affecting litter size is, therefore, pertinent to the swine production industry. This study was conducted to ascertain the effect of age of gilt on the size of their first litters.

Evidence For A Tryptophane Cycle In Neurospora, Francis A. Haskins, Herschel Mitchell

Department of Agronomy and Horticulture: Faculty Publications

The work of Snell on lactic acid bacteria provided the first evidence that anthranilic acid may act as a precursor to tryptophane in vivo. Since the strains of bacteria which utilize anthranilic acid in the place of tryptophane also use indole, it was not possible to establish the order in which these two precursors occurred. In 1943 Tatum, Bonner and Beadle found that anthranilic acid was accumulated in the culture medium by a Neurospora crassa mutant, strain 10575, which required either tryptophane or indole for growth. It was therefore indicated that anthranilic acid is a precursor to indole in …

Separation Of Enzymes On The Filter Paper Chromatopile, Herschel Mitchell, Malcom Gordon, Francis A. Haskins

Department of Agronomy and Horticulture: Faculty Publications

A recent report from this laboratory described a method for isolation of low molecular weight compounds by chromatography on a pile of filter paper disks (1). Preliminary experiments have now been completed on the application of this method to the separation of enzymes. It was expected that a mixture of enzymes could be placed near the top of a filter paper pile and fractionated by imposing a gradient (i.e. pH, organic solvent, or salt concentration) on the column, thus taking advantage of a continuous process. Following the observation of Tiselius (2) it also seemed probable that enzyme separations could be …

4-H Club : Clothing Project "B" Plan, Anna Walker

SDSU Extension Circulars

How the teen-age girl can cover all the necessities of the wardrobe plus the · very special articles of clothing every girl loves might be answered by the slogan "sew your own, and select with care." For school the teen-ager needs clothes that are comfortable and easy to wear as well as smart. Most girls agree that Jeans and Sloppy Joes go for picnics but when it comes to school and occasions where she is out among folks; and wants to look her best it is important to be dressed in "girl's clothes."

Drug Plants Of California, Frederick Louis Beauchamp

University of the Pacific Theses and Dissertations

Many books and articles have been written covering the flora of California. Few, however, have dealt specifically with those plants yielding drug principles used in the materia medica of the medical and pharmacy professions. Over one thousand different species of native and introduced drug plants are growing in the state. Many of these, it is true, have fallen into disuse, either because of lack of medicinal value, or substitutes have been found in the laboratories of the chemist.

The development of the drug farming industry will not only give employment to the state’s increasing population, but will enable our nation …

Effects Of Weather, Sanitation And Chlorinated Chemical Residues On House And Stable Fly Populations On Nebraska Farms, Martin H. Muma, Ephriam Hixson

Department of Entomology: Faculty Publications

Since L. O. Howard's (1906) early report on house flies many entomologists have conducted research on these insects. Their reports range from notes on the hibernation of house flies, Musca domestica L., to lengthy papers on the biology and control of house flies and stable flies, Stomoxys calcitrans (L.). Early control studies stressed the importance of sanitatioll, screening and the use of mist type contact insecticides. These standard control measures have not, however, received much attention in the United States since Wiesmann (1943) reported on the pro-longed effectiveness of a new insecticide "Gesarol." Scores of other workers have also published …

Mechanical Transmission Of A Plant Tumor Virus To An Insect Vector, Karl Maramorosch, Myron K. Brakke, L. M. Black

Department of Plant Pathology: Faculty Publications

Most plant viruses transmitted by leafhoppers have not been demonstrated to be infective in extracts. The virus dealt with in this paper causes tumors in certain susceptible plants, is carried by leafhoppers, and like others in that group has proven difficult to detect in extracts. It is our purpose to recount briefly the variety of methods that failed to transmit the virus and to report on the success of insect-to-insect transmission by injection.

The Lemming Vole, Synaptomys Borealis, In Northern Minnesota, Ralph M. Wetzel, Harvey L. Gunderson

University of Nebraska State Museum: Mammalogy Papers

Lemming voles of the subgenus Mictomys have never been recorded from north-central United States, although they might be expected to occur there judging from records of the species Synaptomys (Mictomys) borealis from southern Manitoba. Recently, examination of specimens in the collection of the Minnesota Museum of Natural History reveals that Synaptomys borealis does occur in north-central United States for we have found the following specimens referable to that species: one immature female (No. 951, MMNH) from Williams, Lake of the Woods County, Minnesota, collected by Gustav Swanson, August 5, 1932; one adult male (No. 2552, MMNH) from Warroad, Roseau County, …

Studies On Larval Trematodes From Tomales Bay, California, Leroy H. Fisk

University of the Pacific Theses and Dissertations

Very little is known of the development, life history, economic importance, of biological relationships of larval trematodes, especially in their molluscan and arthropod hosts on the Pacfic Coast. The comparatively few contributions to our knowledge have been from scattered and fragmentary observations. The purpose of this study was to expand our knowledge and to lay a foundation for further work on trematode life cycles in marine organisms. The area selected for special investigation was Nick's Cove, Tomales Bay, California.
