Transverse Mass And Gravitational Mass, Robert Katz Nov 1961

Transverse Mass And Gravitational Mass, Robert Katz

Robert Katz Publications

A problem suggested by Professor Gamow deals with the relationship between the transverse mass and the gravitational mass: A steamroller of mass m moves horizontally, in the +x direction, with velocity v, in a region of space in which there is a gravitational field intensity g vertically downward. Find the weight of the moving steamroller.

Extension Of The Range Of Northern Pike (Esox Lucius), D. B. Mccarraher Apr 1961

Extension Of The Range Of Northern Pike (Esox Lucius), D. B. Mccarraher

Nebraska Game and Parks Commission: Staff Research Publications

Recent technical publications and popular literature have not fully established the present geographical range of the northern pike. A survey by the writer in 1955 showed that 26 states and Canadian provinces had resident northern pike populations. During the past 5 years pike have been introduced into several other states, thus extending the range. Pike are already established in most of the northern states and are now being released into waters of the south and west.

A Note On Hausdorff Separation, Edwin Halfar Feb 1961

A Note On Hausdorff Separation, Edwin Halfar

Department of Mathematics: Faculty Publications

The examples usually given as instances of topological spaces that have T1-separation but not T2-separation (Hausdorff) also have the property that some compact subset is not closed. This with the classic result concerning closedness of compact subsets of a Hausdorff space suggests the question of the equivalence of Hausdorff separation and the condition that the class of compact subsets be a subclass of the class of the closed subsets of a given space. The following is a simple result of this type and may be of some use in an introductory course in point set topology. …


Sacramento-Wilcox Game Management Area: General Information And Regulations Jan 1961

Sacramento-Wilcox Game Management Area: General Information And Regulations

Nebraska Game and Parks Commission: Publications

The Sacramento-Wilcox Game Management Area was acquired by the Game Commission in 1948 with funds apportioned to the state through the federal excise tax on firearms and ammunition.

The Area serves primarily as a waterfowl refuge, and public hunting area. A game farm, which holds pheasant stock through the winter months is also located on the property.

This state special use area encompasses 2,313 acres of game-rich land with approximately 40 percent of the acreage consisting of lake or lagoon. The remainder is in diversified cropland. The topography is typical of the rainwater-basin country - miles of relatively flat tableland …


Microorganisms And Soil Structure, T. M. Mccalla, F. A. Haskins Jan 1961

Microorganisms And Soil Structure, T. M. Mccalla, F. A. Haskins

Department of Agronomy and Horticulture: Faculty Publications

SUMMARY

Good stable soil structure is valuable for promoting the growth of plants and micro-organisms by permitting enhanced aeration and water penetration and by decreasing erosion under some conditions.

Micro-organisms influence water percolation through the soil. They may plug up soil pores with byproducts of growth and reduce water percolation. On the other hand, if a soil containing a large amount of microbial products is stirred and allowed to dry, then the percolation may be high.

Micro-organisms are involved in stabilizing soil structure by their products of decomposition and their cellular binding material, such as mycelia. Microorganisms differ greatly in …
