Trypsin Inhibitor. V. Nutritive Value Of Treated Soybean Oil Meal And Some Characteristics Of The Trypsin Inhibitor In Soybeans, Raymond Borchers, W. E. Ham, R. M. Sandstedt, C. W. Ackerson, R. H. Thayer, F. E. Mussehl Dec 1947

Trypsin Inhibitor. V. Nutritive Value Of Treated Soybean Oil Meal And Some Characteristics Of The Trypsin Inhibitor In Soybeans, Raymond Borchers, W. E. Ham, R. M. Sandstedt, C. W. Ackerson, R. H. Thayer, F. E. Mussehl

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The marked improvement in the apparent nutritive value of soybean protein after heating has long been recognized. The fundamental cause of this improvement has never been fully understood. Furthermore, commercial soybean oil meal varies considerably in nutritive value although heat treatment is common in most processing plants. Since heating is generally regarded as deleterious to the nutritive quality of protein, the following investigations of various treatments of soybean oil meal are of particular importance in developing a soybean or soybean oil meal of maximum and uniform nutritive value.

A Preliminary Study Of A Physical Basis Of Bird Navigation, Henry L. Yeagley Dec 1947

A Preliminary Study Of A Physical Basis Of Bird Navigation, Henry L. Yeagley

Papers in Ornithology

The bird navigation theory as presented implies an organ or organs in the bird's physiology which are sensitive to the effect of its motion through the vertical component of the earth's magnetic field and to the effort exerted to overcome the coriolis force, due to the earth's rotation. Both these influences involve a set of lines which together form a navigational gridwork. By correlating its instantaneous land speed with the two above effects, a bird can fly to its home which is a unique point in this gridwork, or to related companion points existing in the gridwork at positions other …


Early Life History Of The Oyster Crab, Pinnotheres Ostreum (Say), Mildred Sandoz, Sewell H. Hopkins Dec 1947

Early Life History Of The Oyster Crab, Pinnotheres Ostreum (Say), Mildred Sandoz, Sewell H. Hopkins

VIMS Articles

The first and second zoeae of Pinnotheres ostreum have been described Hyman (1924). The five crab stages parasitic in the oyster (Ostrea virginica) have been described by Stauber (1945). The present paper is an attempt to plete the knowledge of the development of the oyster crab from the egg to the first crab instar. This work was done at the Virginia Fisheries Laboratory in summer of 1944, under the direction of Dr. Curtis L. Newcombe.

The first Pinnotherid larva to be described was the zoea of Pinnotheres pisum Leach, the British pea crab. This species has three or more zoeae. …


Chemical Utilization Of Aspen, Geo J. Ritter, Ralph L. Hossfeld Dec 1947

Chemical Utilization Of Aspen, Geo J. Ritter, Ralph L. Hossfeld

Aspen Bibliography

Chemical utilization of raw materials depends largely on the chemical composition and the chemical and physical properties of the raw materials under consideration. The utilization of wood is no exception to this principle. Thus, a wood having a low percentage of cellulose is uneconomical as a source of wood sugar or pulp for paper; and one of an excessively knotty character is undesirable for chemical conversion Woods having several undesirable characteristics generally fall within the classification of species little used for the purpose. Fortunate! aspen falls outside this class.


Aspen Lumber For Building Purposes, Louis W. Rees Dec 1947

Aspen Lumber For Building Purposes, Louis W. Rees

Aspen Bibliography

Recent shortages of lumber for building purposes make it desirable to seek out all possible supplies of additional lumber. Aspen, according to a study made in northern Minnesota during 1944, 1/ may be a source of lumber largely untapped. The results of that study are the main basis of this paper.

Seasoning Of Aspen, Harvey H. Smith Nov 1947

Seasoning Of Aspen, Harvey H. Smith

Aspen Bibliography

Aspen is nor; the major forest type in the Lake States, and extensive stands are reaching maturity. Increasing quantities are being cut, and much is nor; being put to new and more exacting uses that require better air - seasoning and kiln-drying practices. The recent favorable market for green aspen lumber appears to be falling off, and the time may soon come when operators are no longer able to move green aspen. Such a change can be met by manufacturing better-quality aspen lumber and by carefully seasoning it to the desired moisture content to make it more acceptable. This report …


Machining And Related Properties Of Aspen, Edward M. Davis Nov 1947

Machining And Related Properties Of Aspen, Edward M. Davis

Aspen Bibliography

Aspen occupies 20 million acres of Lake States timber land, or 39 percent of the total forest area. In 1945 there were 6 1/3 billion feet of aspen saw timber 9 inches d.b.h. and larger, and a larger cubic volume of smaller material. The cut of aspen lumber was 152 million board feet in 1946, and the forest could sustain a much larger annual cut.

Thinking Of Others At Christmas, Anna M. Wilson Oct 1947

Thinking Of Others At Christmas, Anna M. Wilson

SDSU Extension Circulars

A true gift is a joy to give and a pleasure to receive. Such a gift doesn't just happen, it grows. It takes thought and planning. Then it takes some doing. Gifts made at home will not stretch the purse strings too far, and they can be hand-tailored to the friend. The best gift may not be wrapped in tissue and ribbon-it might be an invitation to a Christmas tea party. Thinking of others will make Christmas the most joyous season of the year-as it should be.

Bakererpes Fragilis N. G., N. Sp., A Cestode From The Nighthawk (Cestoda: Dilepididae), Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

The examination of an Eastern Nighthawk (Chordeiles m. minor (Forster)), collected September 25, 1945, at Marion, Ohio, revealed numerous, very small cestodes free in the lumen of the small intestine. About fifty specimens were found, but, because of the delicate strobila of this species, few were entire.
Although these cestodes were very thin and translucent, the preparation of well-stained whole mounts presented unusual difficulty. Best results were obtained with a mixture of Ehrlich's and Delafield's haematoxylin stains. Frontal and transverse serial sections, cut at 10 and 15 μm, were made.
This cestode clearly belongs in the sub-family Dilepidinae, but, …

Aspen For Pulp And Paper, E. R. Schafer Oct 1947

Aspen For Pulp And Paper, E. R. Schafer

Aspen Bibliography

Although the use of hardwoods for pulp and paper manufacture has increased considerably during recent years in the Lake States, the pulpwood consumed in this region consists largely of softwood species of which about one quarter is obtained from foreign sources. The wood resource, on the other hand, is comprised to a large extent of hardwoods, predominantly aspen, with the maples, oaks, and several other species available in lesser amounts. The present stand of aspen in the Lake States is estimated at nearly 20 million acres with a total volume of merchantable timber of about 32 1/2 million cords. The …


Milling Of Aspen Into Lumber, C. J. Telford, F. B. Malcolm Oct 1947

Milling Of Aspen Into Lumber, C. J. Telford, F. B. Malcolm

Aspen Bibliography

In the manufacture of aspen lumber, the costs of stumpage and logging approximate 65 per cent of the total, and milling and sales 35 per cent. Milling efficiency is essential, but by itself it is not assurance of a profitable operation.
