Sport Hunting As A Method Of Damage Control, L. Boddicker
Sport Hunting As A Method Of Damage Control, L. Boddicker
Great Plains Wildlife Damage Control Workshop Proceedings
Predator damage control is an area of concern to the livestock producer. He is also often the most likely person to choose sport hunting of coyotes as a recreational activity. Sport hunting of problem coyotes can be an effective tool.
Agricultural producers want to know the skills to control depredating wildlife. A high powered rifle, traps, and various related equipment are standard for most livestock production operations.
Through the Extension effort we attempt to help the producer develop wildlife damage control skills. It is also our responsibility to help develop alternatives to aid the livestock producer with persistent wildlife damage …
On The Bordism Ring Of Complex Projective Space, Claude Schochet
On The Bordism Ring Of Complex Projective Space, Claude Schochet
Mathematics Faculty Research Publications
The bordism ring MU∗(CP∞) is central to the theory of formal groups as applied by D. Quillen, J. F. Adams, and others recently to complex cobordism. In the present paper, rings E∗(CP∞) are considered, where E is an oriented ring spectrum, R=π∗(E), and pR=0 for a prime p. It is known that E∗(CP∞) is freely generated as an R-module by elements {βτ|r≧0}. The ring structure, however, is not known. It is shown that the elements {β …
Secular Climatic Fluctuations In Southwestern Colorado, Raymond S. Bradley, Roger G. Barry
Secular Climatic Fluctuations In Southwestern Colorado, Raymond S. Bradley, Roger G. Barry
Raymond S Bradley
Precipitation and temperature data since records began in southwestern Colorado arc analyzed on a seasonal basis. Interstation correlations for recent years indicate that the region responds fairly uniformly to seasonal variations in precipitation, but this was not true earlier this century when precipitation variability was higher. Changes in the dependence of precipitation on elevation are also shown. Annual precipitation totals were low about 1860, 1900, 1930-35 and 1950-55. Mean annual temperatures appear to have fallen from about 1867 to about 1930 when the trend reversed. Overall, the climate of southwestern Colorado in the 1860s appears to have been warmer and …
Neutron Scattering And The Dispersion Relation In He Ii At Small Momentum Transfer, Robert Hallock
Neutron Scattering And The Dispersion Relation In He Ii At Small Momentum Transfer, Robert Hallock
Robert Hallock
Weighted-least-squares fits to the small momentum transfer (k≤1 Å-1) results of Woods and Cowley have been carried out. We find that the neutron data presently available (i) are not of sufficient accuracy to determine whether or not quadratic terms are present in the dispersion relation and (ii) weakly favor positive dispersion in the absence of the quadratic term.
Brief Theory Of Coherent Processor, Richard C. Heyser
Brief Theory Of Coherent Processor, Richard C. Heyser
Unpublished Writings
The particular coherent data processor which is to be discussed relies heavily upon several basic concepts. These concepts represent a departure from conventional practice and hence the theoretical description must await their presentation in order to gain some continuity. We will accordingly present the underlying assumptions and signal physics prior to description of the processor itself.
Ferroxidase-Ii: A Blood Serum Lipo-Protein, Christine Shih Ming Sung
Ferroxidase-Ii: A Blood Serum Lipo-Protein, Christine Shih Ming Sung
Master's Theses
Ferroxidase-II was definitely identified as a lipoprotein. Cholesterol and phospholipids remained tightly associated with the ferroxidase-II protein following extensive purification. Quantitative analysis showed that it is a high-density lipoprotein. Thin-layer chromatographic analyses indicated that phosphatidylcholine accounts for the majority of the bound phospholipid with lysophosphatidyl choline and sphingomyel in accounting for the remaining phospholipid.
Treatment of purified ferroxidase-II with phospholipase C or A resulted in a loss of ferroxidase activity which paralleled the hydrolysis of phospholipid. Phospholipid D treatment also resulted in the loss of ferroxidase activity, yet the loss was not as great as with other phospholipases. A lipid-depleted …
Crayfish, Leech, And Snail Control
Crayfish, Leech, And Snail Control
Great Plains Wildlife Damage Control Workshop Proceedings
We have effective results in controlling crayfish in our ponds using Baytex. Baytex is a higly toxic compound that effects the nervous system of many organisms. Used in small concentrations it will kill crayfish without hurting fish. We use Baytex at 40 ppb. We normally dilute the required amount of chemical with water and then mix it thoroughly in the pond. Leeches can be controlled using Dylox. Masoten is another trade name for dylox. The recommended rate of application is 1/2 ppm. This should be applied in a manner so it is thoroughly mixed in the ground. Recommened treatment for …

Summary, Dan F. Dickneite
Great Plains Wildlife Damage Control Workshop Proceedings
During this workshop we have heard from some of the leading animal damage control and livestock management specialists in the Great Plains and adjoining states. It appears that western states personnel will likely be involved in wild animal damage control to a greater extent than before as control activities are passed from federal to the separate state agencies--hopefully, with financial assistance for both implementation and research.
There is no widespread agreement on numbers or severity of damage, or on the best damage control techniques to use. What works in one area of the country will not necessarily work in another. …
How Important Are Livestock Management Methods To The Orevention And /Or Reduction Of Losses To Coyotes, Don Good
Great Plains Wildlife Damage Control Workshop Proceedings
Professor.E. K. Faulkner, Extension Sheep Specialist from the University of Wyoming, stated that fencing the range was too expensive to be practical. He indicated that flares, pop-guns, color painting on sheep, and dogs have been used to cut down losses to coyotes but these methods have not been nearly so effective as the use of cyanide guns and 1080. He also indicated that losses to coyotes along with labor problems are the number 1 and 2 reasons for 200 sheepmen going out of the business the past 5 years in the range country. He said that shed lambing or lambing …

Extension Wildlife Damage Control In Arkansas, Rocky Lynch
Extension Wildlife Damage Control In Arkansas, Rocky Lynch
Great Plains Wildlife Damage Control Workshop Proceedings
With the curtailment of a service type predator control program that existed in Arkansas for 29 years, the Arkansas Game and Fish Commission in 1970 initiated a Nuisance Animal Control Section within the framework of the Commissions' Game Division. This extension - demonstration type wildlife control unit was named such because of the increase in rodent control (beaver and muskrat) within the state. Their numbers were spawned by the habitat inhancement in the delta and timber growing regions of Arkansas.
A Game Biologist visited the Missouri Department of Conservation and observed the technique of their predator control agent. With ideas …

A Pycnometer Of Improved Design, Richard Moore
A Pycnometer Of Improved Design, Richard Moore
Journal of the Minnesota Academy of Science
The density of a solution must be known to laboratory medicine , biochemistry, and physical chemistry. Knowledge of the density may permit calculation of solution concentration, solute molecular weight, solute partial, or specific volume , for example. Therefore, the determination of the density of a solution is a measurement which must be made with precision, accuracy, and sensitivity. This report describes a pycnometer which permits making such measurements.
The Evaluation Of Glasser's Maximum Likelihood Method On Missing Data In Regression, Gayle M. Yamasaki
The Evaluation Of Glasser's Maximum Likelihood Method On Missing Data In Regression, Gayle M. Yamasaki
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Missing data in regression is often a problem to research workers because standard regression methods are applicable only to complete data sets. At present there are three general methods for solving the problem of missing data.
At first, the reduced data method, reduces the incomplete data set to a complete data set before analyzing. Although this method is very simple to apply, substantial amounts of information are sometimes lost when data is eliminated. This results in less precise estimates of the regression parameters.
The second method, generalized least squares, estimates the missing values through least squares techniques, thus obtaining a …

Integer Programming By Cutting Planes Methods, Sung-Yen Wu
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Linear programming is a relatively new, very important branch of modern mathematics and is about twenty five years old.
In this day and age, most planners and decision makers will acknowledge that some linear optimization problems are worth the expense and trouble to solve. Using linear programming technique as a tool to make decision plannes are able to greatly redice cost or increase profit for any project under consideration.
Since Dr. George B. Dantzig published his first paper on the simplex method in 1947, progress in that field has been rapid. Although the first applications were military in nature, it …

Recursive constructions are given which permit, under conditions described in the paper, a (v, b, r, k, lambda)-configuration to be used to obtain a (v', b', r', k, lambda)-configuration.
Although there are many equivalent definitions we will mean by a (v, b, r, k, lambda)-configuration or BIBD that (0, 1)-matrix A of size v x b with row sum r and column sum k satisfying
AAT = (r - lambda)I + lambdaJ
where, as throughout the remainder of this paper, I is the identity matrix and J the matrix with every element +1 whose sizes should be determined from …

A Note On Amicable Hadamard Matrices, Jennifer Seberry
Faculty of Informatics - Papers (Archive)
The existence of Szekeres difference sets, X and Y, of size 2f with y E Y = -y E Y, where q = 4f + 1 is a prime power, q = 5 (mod 8) and q = p2 + 4, is demonstrated. This gives amicable Hadamard matrices of order 2(q + 1), and if 2q is also the order of a symmetric conference matrix, a regular symmetric Hadamard matrix of order 4q2 with constant diagonal.

Hadamard Matrices Of Order 28m, 36m, And 44m, Jennifer Seberry
Faculty of Informatics - Papers (Archive)
We show that if four suitable matrices of order m exist then there are Hadamard matrices of order 28 m, 36 m, and 44 m. In particular we show that Hadamard matrices of orders 14(q + 1), 18(q + 1), and 22(q + 1) exist when q is a prime power and q = l(mod 4).
Also we show that if n is the order of a conference matrix there is an Hadamard matrix of order 4mn. As a consequence there are Hadamard matrices of the following orders less than 4000:
476, 532, 836, 1036, 1012, 1100, 1148, 1276, 1364, …
Recent Advances In The Construction Of Hadamard Matrices, Jennifer Seberry
Recent Advances In The Construction Of Hadamard Matrices, Jennifer Seberry
Faculty of Informatics - Papers (Archive)
In the past few years exciting new discoveries have been made in constructing Hadamard matrices. These discoveries have been centred in two ideas:
(i) the construction of Baumert-Hall arrays by utilizing a construction of L. R. Welch, and
(ii) finding suitable matrices to put into these arrays.
We discuss these results, many of which are due to Richard J. Turyn or the author.

A List Of Balanced Incomplete Block Designs For R < 30, Jane W. Di Paola, Jennifer Seberry, W D. Wallis
Faculty of Informatics - Papers (Archive)
A balanced incomplete block design consists of a set of v elements arranged into b k-element subsets called blocks such that each element occurs r times and each pair of elements appears in lambda distinct blocks. The numbers v,b,r,k,lambda are called the parameters of the design. A necessary condition that a design exist is that the parameters be integers satisfying:
(1) vr = bk
( 2) r(k-1) = lambda (v-1)

Sloane and Seidel have constructed (n,2n,1/2(n-2)) and (n-1,2n,1/2(n-2)) codes whenever n = 1 + a2 + b2 = 2(mod 4), a,b integer, is the order of a conference matrix. We give constructions for (n,2n,1/2(n-2)) and (n-1,2n,1/2(n-4)) codes when n = 2(mod 4) and conference matrices cannot exist.
In particular we give results for n = 22, 34, 66, 70, 106,130,154,162,202,210, ... ,"210, ... , but our codes are not as ""good" as those from Hadamard matrices or of Sloane and Seidel".

Geology Of The Country East Of The Santa Rita Mining District, Grant County, New Mexico: The San Lorenzo Area, Raymond S. Lambert Jr.
Earth and Planetary Sciences ETDs
The settlement of San Lorenzo is approximately 19 miles east of Silver City, New Mexico. The area consists of rolling hills, relatively steep slopes and the broad Mimbres River Valley. The land surface reflects partial erosion of Basin and Range fault blocks. The maximtun elevation is 7,170 feet, with relief of 1,400 feet.
The main structural feature is a northwest trending mountain range, which is a west-southwest-dipping fault block bounded on the northeast by the Mimbres fault. Vertical displacement ranges from 150 meters (500 feet) to 1,200 meters (4,000 feet). Rocks exposed along the steep northeastern escarpment range in age …

Some Matrices Of Williamson Type, Jennifer Seberry
Some Matrices Of Williamson Type, Jennifer Seberry
Faculty of Informatics - Papers (Archive)
Recent advances in the construction of Hadamard matrices have depended on the existence of Baumert-Hall arrays and four (1,-1) matrices A, B, C, D of order m which are of Williamson type; that is, they pairwise satisfy
(i) MNT = NMT, and
(ii) AAT + BBT + CCT + DDT = 4mIm
We show that if p = 1 (mod 4) is a prime power then such matrices exist for m = 1/2p(p+1). The matrices constructed are not circulant and need not be symmetric. This means there are Hadamard …

A balanced incomplete block design or BlBD is defined as an arrangement of v objects in b blocks, each block containing k objects all different, so that there are r blocks containing a given object and lambda blocks containing any two given objects.
In this note we shall extend a method of Sprott [2, 3] to obtain several new families of BIBD's. The method is based on the first Module Theorem of Bose [1] for pure differences.
We shall frequently be concerned with collections in which repeated elements are counted multiply, rather than with sets. If T1 and T …

R. J. Turyn introduced complex Hadamard matrices and showed that if there is a complex Hadamard matrix of order c and a real Hadamard matrix of order h > 1, then there is a real Hadamard matrix of order hc.
Previously, complex Hadamard matrices were only known for a few small orders and the orders for which symmetric conference matrices were known. These latter are known only to exist for orders which can be written as 1 + a2 + b2 where a, b are integers.
We give many constructions for new infinite classes of complex Hadamard matrices and …
A Nonparametric Solution For Finding The Optimum Useful Life Of Equipment, Barry T. Stoll
A Nonparametric Solution For Finding The Optimum Useful Life Of Equipment, Barry T. Stoll
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
It is often the case that equipment used by industry must be replaced with new equipment from time to time either because frequent malfunctions make it too costly to repair, or because the equipment has simply worn out. The new equipment often has the nature of either malfunctioning soon after installation due to manufacturing defects, or functioning for an extended period of time because it is free of these defects. For this reason, equipment is often given a preliminary running called the burn-in which gives no useful output but merely tests for manufacturing defects. Also, after a given amount of …

Computer Programs Supporting The Teaching Of Statistics, Chien-Hwa Liu
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
During the past few years there has been an increasing interest in developing computer packages to enhance the teaching of elementary statistics. The conventional ways of teaching statistics have used such devices as desk calculators, tables of functions, short-cut calculating formulas and electronic calculators, etc. to manipulate the involved computations. Electronic computers, in the past decade, have been broadly used in universities and colleges in many ways. It is only natural to extend the use of computers to the teaching function. Remote terminals can now be installed in any classroom and bring the computer to the students.
