Measurement Of Irrigation Water, Eldon M. Stock

Reports

Foreword: Although irrigation has been practiced in Utah for more than one hundred years, irrigation water still is being distributed to farmers with little or not thought about its measurement. A farmer would not think of buying or selling other farm commodities, such as hay, grain, beef cattle, or dairy products, without weighing or accurately measuring them, but at the same time he is often content to accept and pay for the irrigation water received with little or no knowledge as to the actual amount received, or whether or not he is receiving the amount he is entitled to. Measurement …

Some Remarks On Elementary Divisor Rings Ii, Melvin Henriksen

All HMC Faculty Publications and Research

A commutative ring S with identity element 1 is called an elementary divisor ring (resp. Hermite ring) if for every matrix A over S there exist nonsingular matrices P, Q such that PAQ (resp. AQ) is a diagonal matrix (resp. triangular matrix). It is clear that every elementary divisor ring is an Hermite ring, and that every Hermite ring is an F-ring (that is, a commutative ring with identity in which all finitely generated ideals are principal).

An Isomorphism Theorem For Real-Closed Fields, P. Erdös, L. Gillman, Melvin Henriksen

All HMC Faculty Publications and Research

A classical theorem of Steinitz states that the characteristic of an algebraically closed fields, together with its absolute degree of transcendency, uniquely determine the field (up to isomorphism). It is easily seen that the word real-closed cannot be substituted for the words algebraically closed in this theorem. It is therefore natural to inquire what invariants other than the absolute transcendence degree are needed in order characterize a real-closed field.

Birds Of Jasper National Park, Alberta, Canada, Ian Mctaggart Cowan

Other Publications in Wildlife Management

Jasper Park, with an area of approximately 4,200 square miles, is the largest accessible primeval wildlife sanctuary on this continent and as such its bird life is of the greatest interest. The meagre available records of earlier conditions indicate that noteworthy changes in the park's avifauna have taken place in the last 50 years. There can be little doubt that other changes will take place during the years to come. For this reason, then, if for no other, it seems desirable that as complete a record as possible of the current situation be made, for only against it can the …

Why Doesn't Such-And-Such A Game Bird Do Well In Nebraska?, Levi Mohler

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

Why doesn't such-and-such game bird do well in Nebraska? This is a question which is often asked field workers for the game department. The answer to such an inquiry varies with the bird in question, but in general the following applies: Since climate, topography, and natural foods vary so much from place to place, and since most individual species are not highly adaptable, nature has through the centuries evolved many species, or kinds, of birds, each species adapted to meet certain conditions. Some of these have extensive ranges; others are limited in their distribution. The conditions suited to one species …

Federal Aid In Wildlife Restoration, Ronald A. Ryder

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

This report represents a compilation, analysis and summarization of data collected on the South Platte Management Area and deals primarily with game bird data collected by personnel of Project W-37-R. History, general description, and methods of operation are discussed, and recommendations for future operations given.

Briefly, the South Platte Management Area is located in Logan and Sedgwick counties, comprising over 11, 400 acres of state-owned land in four separate segments. The largest segment (more than 12,000 acres of deeded and leased land) lies along the South Platte River from Proctor to Red Lion. This, and a second area of 240 …

Spring Prairie Grouse Census - 1955, Reuel Janson

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

The 1955 spring prairie grouse census was conducted during the period March 30 to May 4. Census data were obtained by means of a survey of dancing and booming grounds on 18 automobile transects.

An average population density of 4.77 sharptailed grouse, and 0.71 prairie chickens per square mile was found. Comparable data for 1954 and 1955 indicate a 10 percent decline in the combined prairie and grouse population. The prairie chicken population declined considerably more than the sharptail population.

The extreme northern portion of the grouse range, Corson and Perkins Counties, experienced population gains of approximately 50 percent which …
