Bulletin No. 342 - The Nutritive Content Of The Grazing Sheep's Diet On Summer And Winter Ranges Of Utah, C. Wayne Cook, Lorin E. Harris Jan 1950

Bulletin No. 342 - The Nutritive Content Of The Grazing Sheep's Diet On Summer And Winter Ranges Of Utah, C. Wayne Cook, Lorin E. Harris

UAES Bulletins

Approximately two million sheep graze the native ranges of Utah each year. These animals are on the range most of the year and their food supply must come from range plants as they are normally selected. The nutritive value of range forage is often borderline or deficient in essential nutrients, yet, sufficiently adequate to prevent obvious physiological disorders. These mild deficiencies may affect the productive efficiency of the animal even though no symptoms are apparent.

Optimization Of Parameters For Soft-Nip Calendering Of Uncoated Paper, Jung-Kyu Yang Jan 1950

Optimization Of Parameters For Soft-Nip Calendering Of Uncoated Paper, Jung-Kyu Yang

Paper Engineering Senior Theses

The major reason for calendering is to impart both smoothness and gloss on paper. Smoothness, which is the degree of flatness of the surface, and gloss, which is a measurement of light reflectance, are unrelated parameters. However, both smoothness and gloss are related to printing process. Strength properties affect the printing machine runability. In general, calendering reduces strength properties of the paper. The degree of finish obtained in a soft-nip calendering depends on characteristics of the paper, such as moisture content and type of filling materials. The purpose of this study is to determine the best conditions for soft-nip calender …


Influence Of Eastern Redcedar On Soil In Connecticut Pine Plantations, Laurence C. Walker, R.A. Read Jan 1950

Influence Of Eastern Redcedar On Soil In Connecticut Pine Plantations, Laurence C. Walker, R.A. Read

Faculty Publications

Physical and chemical properties of surface soil beneath eastern redcedar trees in pine plantations in Connecticut were found to be different from those beneath adjacent pines. Properties of the surface soil beneath redcedars were apparently influenced by the specific chemical nature of the cedar leaflitter, its decomposition products, and subsequent' incorporation in the soil by earthworms.


Safflower Production In The Western Part Of The Northern Great Plains, C. E. Classen Jan 1950

Safflower Production In The Western Part Of The Northern Great Plains, C. E. Classen

Nebraska Agricultural Experiment Station: Historical Circulars

Recent development of new varieties with seeds averaging more than 30 per cent oil give safflower a good chance of becoming an important oil seed crop in the United States. It is the purpose of this circular to acquaint farmers with the crop and to outline the most promising production practices for those who undertake its production in the western part of the northern Great Plains.

The Texas Species Of Thelesperma (Compositae), Lloyd H. Shinners

Field and Laboratory

Seven genera of Compositae-Heliantheae-Coreopsidinae as delimited by Hoffman (1894) are found in Texas….Thelesperma has been the subject of partial synopses and extended. notes (Gray, 1884; Rydberg, 1900; Blake, 1928), but has never been revised. The genus reaches its greatest development in Texas and northern Mexico; seven of the thirteen known species are included in the following synopsis. The remaining six are listed at the end for the convenience of those interested.
