Tillage Methods In Grasshopper Control, Gerald B. Spawn

Agricultural Experiment Station Entomology Pamphlets (1940-1952)

The eyes of the world are turned toward the American farmer as the individual to whom they must look for the production of a plentiful supply of food for our fighting forces, our Allies and for the hungry millions as they are liberated from Nazi rule and devastation. Grasshoppers have done much to defeat the Great Plains farmers in their effort to produce this food. In the central part of our State many fields of corn, badly needed for feed, were planted during the past year from which not one bushel of grain was harvested. Numerous fields of flax, very …

Periods Of Fossil Filling And Replacement As Indicators Of Climate, William Otis Ham Jr.

Field and Laboratory

Embedded within the gray Permian limestones of the Finlay Mountains, trans-Pecos, Texas, are abundant remains of fusulinids, bryozoans, and brachiopods. Most of the fossil tests which are exposed on weathered surfaces are partially, or wholly, replaced by a form of impure silica. The fusulinids especially are characterized by such replacements and stand out in sharp relief above the weathered surfaces of the limestones that contain them. Besides the one period of silicification exhibited by these fossils, two periods of calcite filling are evidenced also…. These three distinct periods deserve an explanation. As suggested in this paper, local climatic changes might …

Plant Diseases Common, Destructive, Preventable In South Dakota (Revised), W.F. Buckhholtz

Agricultural Experiment Station Plant Pathology Pamphlets (1942-1962)

Abundant agricultural production is a victory goal and in South Dakota is based on an abundance of feed, forage and cash field crops and an adequate home vegetable and fruit supply. On the other hand, soil conservation and the maintenance of South Dakota’s agricultural productivity depends on a practice of moderate rather than wholesale over-cropping of cultivated land. Shortages of labor and machinery place a definite limit on the amount of really good farming that can be done it South Dakota for the duration of the war. One of the ways to insure maximum crop production from a minimum of …

Food From The Sea: Fish And Shellfish Of New England, Rachel L. Carson

United States Fish and Wildlife Service: Publications

Millions of Americans are developing new wartime food habits, trying foods they once neglected, turning to alternates for long familiar products. For everyone of the ten fish or shellfish that make up mere than four-fifths of New England's catch there are seven species little known or utilized, many of which could provide tasty and nutritious foods. Turning to these under-utilized species will conserve food resources by lifting the burden of over-exploitation from such fishes as cod and haddock and will augment dwindling supplies of protein foods. Exploring the seafood markets for unfamiliar species rewards the housewife and her family with …

Effect Of Manganese And Iodine Additions In A Specific Ration For Laying Hens, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Circulars

This preliminary experiment does not answer all of the questions that are presented about manganese and iodine requirements. It can only be taken to indicate that for a typical situation with a typical ration of the type that many poultry producers use, there was no satisfactory evidence that egg production, hatchability and the viability of the hens was limited by manganese and iodine in the ration.

Catalysis And The Chemical Industry, Harold E. Abbott

Field and Laboratory

Before the advent of organized chemistry, alchemists were searching for a "philosopher's stone," a hypothetical substance which was reputed to be able to turn basic metals into the precious metal, gold. While their crusade was never rewarded with success, they laid the foundation for the chemical study of today. In this field a catalyst for a desirable chemical reaction has turned out to be a true "philosopher's stone." Catalysts have played an important part in the production of substitutes which are very useful in today's limited markets.

An Elementary Experiment In Insolation, John D. Boon

Field and Laboratory

Meteorology, the neglected science, is coming into its own. This new interest is due to the rapid development of airplane transportation, the radio, and the Second World War. Slowly we are beginning to learn that while our feet may be upon the solid earth, we live in the atmosphere, and this atmosphere is influencing and often controlling our lives.

Abnormal Salt Water Pressures On The Texas And Louisiana Coast, Harold Denton

Field and Laboratory

The occurrence of abnormal salt-water flows, as well as abnormal gas pressures, has been more common on the Gulf Coast in the last few years, than at any other time in the history of Gulf Coast drilling. This increase in frequency of abnormal well pressures may be attributed to the present trend of deeper drilling depths. In general, most abnormal pressures on the Gulf Coast occur below depths of 7,500 feet, the exceptions being found in erratic sands on the penetrating type salt domes.

Studies On Restaurant Sanitation And The Effect Of Sodium Azide On The Physiology Of Streptococcus Salivarius, Kenneth D. Rose

Open Access Master's Theses (through 2010)

Whether restaurant eating utensils serve as vectors in the transmission of respiratory and related diseases is still a matter for question, in spite of the overwhelming evidence in support of this contention.This is due to largely to the lack of epidemiological evidence, the tracing of an outbreak of a disease directly and unquestionably to contaminated eating utensils.The very nature of the vectors concerned obviates any possibility of obtaining this epidemiological evidence, since the contaminating agent exists as such only momentarily at the best. This research problem was undertaken with the hope that a technique designed to demonstrate the appearance of …

Increases In Aphid Populations On Potato Plants Sprayed With Zinc Arsenite In Western Nebraska, Roscoe E. Hill, H. Douglas Tate

Department of Entomology: Faculty Publications

During the 1941 growing season, field observations in western Nebraska indicated that aphids, Myzus persicae (Sulz.), were becoming abundant in experimental potato plots that had been treated with zinc arsenite-lime sulfur spray for controlling potato flea beetles, Epitrix cucumeris (Harr.), and the potato psyllid, Paratrioza cockerelli (Sulc.). Detailed examinations of leaves showed that significantly greater populations were present on the sprayed than on the untreated plants. Evidence of slight increases also was noted on plants dusted with a barium fluosilicate and sulfur mixture.

Nebraska Cattle Grub Survey, Lewis T. Graham, H. Douglas Tate

Department of Entomology: Faculty Publications

The scarcity of data on the actual extent of cattle grub infestation in Nebraska became evident during the winter of 1942--43 when a control program was being organized. Although there were some cattlemen who were acutely aware of the losses occasioned by this pest, there were many others who had given the problem little thought or who believed that infestation resulted largely from the importation of feeder cattle. More detailed information was obviously desirable in order to present an accurate and convincing account of the problem to the cattle growers.
