A Preliminary Investigation Of The Species Of Water Mites Of The United States Rocky Mountain Region And Vicinity Of Albuquerque, New Mexico, David W. Bergstrom Jan 1951

A Preliminary Investigation Of The Species Of Water Mites Of The United States Rocky Mountain Region And Vicinity Of Albuquerque, New Mexico, David W. Bergstrom

Biology ETDs

The primary purpose of this research problem is to give a preliminary accounting of the species of Hydracarina or water mites found at several mountain localities in Colorado, Wyoming, Utah, Montana, and New Mexico. In general, since the collecting was confined to altitudes above 4500 feet, the results of this problem constitute a survey of some of the highest forms of water mites of the United States.

Notes On The Agave Feeders Of The Genus Megathymus (Lepidopter Rhopalocera, Megathymidae), H. A. Freeman Jan 1951

Notes On The Agave Feeders Of The Genus Megathymus (Lepidopter Rhopalocera, Megathymidae), H. A. Freeman

Field and Laboratory

Life histories of most of the species of Megathymus long have been associated with the genus Yucca; but John A. Comstock & Charles M. Dammers found that Megathymus stephensi Skinner has as its food plant a certain species of the genus Agave (Bull. So. Calif. Acad. Sci., XXXIII, 1934). Later, it was found that another species of Megathymus feeds in the larval stage upon agave. Although I have been unable to find any published note on the feeding of Megathymus mariae B.&B. upon Agave lecheguilla Torrey, lepidopterists have known this fact for a considerable time. There remain four species of …


Increase Of Poison-Bitterweed (Hymenoxys Odorata) On Texas Range Lands, V. L. Cory Jan 1951

Increase Of Poison-Bitterweed (Hymenoxys Odorata) On Texas Range Lands, V. L. Cory

Field and Laboratory

This paper, as read before the Texas Academy of Science, was titled "Increase of Native Weedy Forbs on Texas Range Lands." The reason for the change of title here is that, from a range standpoint, not all forbs are weeds and not all weeds are forbs. Forbs are herbaceous plants that are not grasses or grass-like plants. Some of the forbs are toxic to livestock or so unpalatable to them they feed upon them only when excessively hungry or starving. In reality some of these range forbs are forage plants and some are not.


The Texas Species Of Psoralea (Leguminosae), Lloyd H. Shinners Jan 1951

The Texas Species Of Psoralea (Leguminosae), Lloyd H. Shinners

Field and Laboratory

Twenty-five species and two varieties of Psoralea, dis­ tributed among three segregate genera, were recognized from Texas by Rydberg (1919) and by Tharp and Barkley (1945, 1946). Fourteen species and four varieties, of which one species and three varieties are newly described, are recognized in the present synopsis, all treated under Psoralea. For the most part the dismemberment of the genus is entirely reasonable as far as Texas species are concerned.

Forest Fires In The Northern Rocky Mountains, J S. Barrows Jan 1951

Forest Fires In The Northern Rocky Mountains, J S. Barrows

The Bark Beetles, Fuels, and Fire Bibliography

This is a report on an analysis of 36,000 forest fires in the northern Rocky Mountains. The analysis was made to gain a better understanding of the occurrence, behavior, control, and effects of fires, and in turn to obtain essential information required for improved planning and management of fire protection systems. The results present answers to these questions: 1) What is the magnitude of the regional fire problem? 2) What are the basic features of fire behavior under various topographic, fuel, and weather conditions? 3) What have been the results of organized fire control programs including fire prevention, detection, communication, …

Bulletin No. 350 - Cemeteries Of Box Elder And Summit Counties, Joseph A. Geddes, Carmen Fredrickson Jan 1951

Bulletin No. 350 - Cemeteries Of Box Elder And Summit Counties, Joseph A. Geddes, Carmen Fredrickson

UAES Bulletins

One of man's greatest challenges is to build institutions that adequately meet basic needs. A cemetery is a social institution invented to take care of needs related to the dead.

Times and conditions change. A design which seemed adequate when initiated may soon become archaic and out-moded if it is not modified in the light of new discoveries.

This study raises many issues about cemeteries. As one reads the bulletin many questions concerning the nature and function of other institutions arise. What is their condition in contrast with the cemeteries?

This publication, the first in an institution series planned by …


The Effects Of Thermal-Neutron Irradiation Of Maize And Barley Kernels, John W. Schmidt, E. F. Frolik Jan 1951

The Effects Of Thermal-Neutron Irradiation Of Maize And Barley Kernels, John W. Schmidt, E. F. Frolik

Nebraska Agricultural Experiment Station: Historical Research Bulletins

It is the purpose of this paper to report the effects of thermal-neutron irradiation of maize and barley kernels on subsequent germination, plant establishment, and early plant development. Comparisons are made with equivalent neutron treatments of maize pollen, results of which have been reported in part in previous publications.


Cinderella Furniture, Isabel Mcgibney Jan 1951

Cinderella Furniture, Isabel Mcgibney

SDSU Extension Circulars

With an elaborate gilt coach that had once been a pumpkin, and glass slippers that didn't disclose their former identity, a common colorless girl became a famous storybook beauty. With a wave of the magic legendary wand, the good fairy transformed the unattractive into the desirable, the ugly into the beautiful and the rundown into the useful. Today a woman is her own fairy. The magic wand that makes the old as good as new is imagination, ingenuity and know-how. Like the two chairs on the cover that Mrs. Homemaker proudly shows her family, the unattractive chair has completely changed …


Comparison Of Three Stiffness Testers, Arne H. Anderson Jan 1951

Comparison Of Three Stiffness Testers, Arne H. Anderson

Paper Engineering Senior Theses

Stiffness is defined and some of the factors affecting stiffness are given. Also, the underlying principles upon which most stiffness testers are based are given.

Three of the commonly used stiffness instruments are used for this comparison study. They are: Gurley, Smith-Taber, and the Clark. The correlation between the instruments is determined and the stiffness range that each instrument is best suited for is noted.

Effect Of Low Temperature On The Germination Of Artificially Dried Seed Corn, J. E. Livingston Jan 1951

Effect Of Low Temperature On The Germination Of Artificially Dried Seed Corn, J. E. Livingston

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Soil pathogens were primarily responsible for the reduction in emergence of corn seedlings following the cold treatment. The susceptibility of the seedlings to soil pathogens was much greater when the seedlings were exposed to a soil temperature of 5° C for 7 to 14 days than when they were held continuously at 20° C. Seedling emergence was in inverse relation to kernel moisture content at time of harvest. Artificial drying of the seed intensified this effect, particularly in nonsterile soil. Treatment of the seed with Arasan prior to planting completely eliminated the effect of soil pathogens on seedling emergence either …


The Utilization Of Food Elements By Growing Chicks. Xiii. The Effect Of Additions Of Dehydrated Alfalfa Meal To High Corn Chick Rations, C. W. Ackerson, R. L. Borchers, F. E. Mussehl Jan 1951

The Utilization Of Food Elements By Growing Chicks. Xiii. The Effect Of Additions Of Dehydrated Alfalfa Meal To High Corn Chick Rations, C. W. Ackerson, R. L. Borchers, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Feeding trials were conducted on three groups of chicks in eight lots receiving a growing mash containing dehydrated alfalfa meal at levels of 2, 3, 4, 5, 6, 9, 10, 12, and 15 per cent. Comparisons were not made simultaneously but no general trend toward growth depression was evident in comparable lots. In addition duplicate trials of four lots of newly hatched New Hampshire chicks were made on pelleted rations carrying 0, 2, 4, and 6 per cent of a good quality dehydrated alfalfa meal. The chicks were all fed accurately known amounts of the pelleted rations for six weeks. …
