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
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
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
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. …

The Utilization Of Food Elements By Growing Poults, C. W. Ackerson, F. E. Mussehl
The Utilization Of Food Elements By Growing Poults, C. W. Ackerson, F. E. Mussehl
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
1. Day-old poults were found to contain an average of 1.28 g nitrogen, 0.18 g calcium and 0.15 g phosphorus. 2. Day-old poults were fed equal amounts of a good growing ration for 52 days. Analysis of these poults showed retention of 42.6 per cent of the nitrogen, 23.4 per cent of the calcium and 31.3 per cent of the phosphorus contained in the ration. 3. Retentions of nitrogen, calcium and phosphorus were on the same order as those obtained in like feeding trials with chicks.

Mattamuskeet: A National Wildlife Refuge, Rachel Carson
United States Fish and Wildlife: Staff Publications
Mattamuskeet, Pea Island, and Swanquarter-- two on the mainland and one on the outermost barrier beach--are three National Wildlife Refuges in North Carolina that provide winter food and shelter for more than 100,000 waterfowl. Ducks, geese, and swans that in summer scatter across the northern rim of the world from Greenland to Alaska come down the sky lanes in the fall and in these refuges find the conditions they need to survive the hard months of winter.
At Mattamuskeet you can see one of the largest assemblages of Canada geese on the Atlantic seaboard and more of that giant white …

Parker River: A National Wildlife Refuge, Rachel Carson
Parker River: A National Wildlife Refuge, Rachel Carson
United States Fish and Wildlife: Staff Publications
The Parker River National Wildlife Refuge is New England's most important contribution to the national effort to save the waterfowl of North America. Many million Americans have a direct stake in the success of this effort: the 2,000,00o waterfowl hunters, the millions who find recreation and esthetic pleasure in observing and photographing the birds, and all those, whom there is no way of counting, who understand the value of preserving wildlife as part of America's natural heritage.
During the several generations in which the United States has been converted from a land preeminently wild and unsettled into an industrial and …

Chincoteague: A National Wildlife Refuge, Rachel Carson
Chincoteague: A National Wildlife Refuge, Rachel Carson
United States Fish and Wildlife: Staff Publications
The national wildlife refuge at Chincoteague, Virginia, is one of the newest in a chain of sanctuaries placed along the flight lanes of the waterfowl. Coming down from the north the principal links of the chain are Parker River, Montezuma, Susquehanna, Brigantine, and Bombay Hook. Then from Chincoteague the links run south, through Back Bay and Pea Island, Mattamuskeet and Cape Romain. Chincoteague, like other waterfowl refuges, is needed because birds migrate, and because in so doing they expose themselves to great dangers.
The migration of birds is one of the ancient spectacles of earth, and one of the most …
Mammals Of Utah County, James W. Bee
Mammals Of Utah County, James W. Bee
Student Works
Based on the premises that an accurate determination and description of the mammals of Utah County is a prerequisite for subsequent research in ecology, geographic distribution and evolutionary taxonomy, this thesis is submitted. While it is essentially taxonomic, there are included related subjects to permit a more thorough interpretation of the subject as a whole.
Summarizing, the objectives are:
- a. To list and key the known mammals of Utah County with descriptions and measurements.
- b. To ascertain their geographic range within the county.
- c. To present significant ecological and geological data for the proper appreciation of the problems of evolutionary …
