A Study Of The Endogenous Electron Donors For Nitrogen Fixation By Cell-Free Extracts Of Klebsiella Pneumoniae M5al (Aerobacter Aerogenes M5al), Elisabeth Yi-Jan Wu

Electronic Theses and Dissertations

Biological nitrogen fixation, the mechanism of the enzymatic conversion of the inert nitrogen gas into amino acids in the cytoplasm of the microorganism has puzzled many scientists for decades. The recent discovery of some free-living nitrogen-fixing bacteria has encouraged the investigation of this mechanism. A big step taken in the rapid elucidation of this mechanism was the first reproducible cell-free nitrogen-fixing system from Clostridium pasteurianum successfully obtained by Carnahan et al. (9) in 1960. In the following decade, reproducible cell-free systems were demonstrated with the strict aerobe, Azotobacter vinelandii (4), facultative anaerobic Bacillus polymyxa (16) and Klebsiella pneumoniae (31) and …

Electronic Theses and Dissertations

Because this home economics teacher had a desire to become involved with the new trends in education, she chose to compare the effectiveness of an independent method and a traditional method of teaching a self-developed, three week consumer education unit to 31 girls in a Home Economics II class at Madison Senior High School, Madison, South Dakota. The effectiveness of each teaching method was to be measured by the change in scores of a pretest and a post test. An attempt was made to place equal numbers of high-, average-, and low-ability students in each group and to compare the …

The Effects Of Acute Ammonia Toxicity On Certain Homogram Parameters In Sheep, William C. Kirkpatrick

Electronic Theses and Dissertations

Due to the rapidly expanding human population, one of the greatest problems facing agricultural scientists is the development of adequate food resources to meet the growing demand for quality protein. The development of more economical and higher quality feed for ruminant animals is essential since they are one of man's primary sources of animal protein. Microorganisms in the ruminant stomach convert relatively cheap non-protein nitrogen compounds into bacterial proteins, which are digested, absorbed, and utilized by the host animal. Urea, a common non-protein nitrogen compound, is hydrolyzed into ammonia and carbon dioxide by bacterial urease. When urea is hydrolyzed faster …

There are a great many problems in education today. One of them is the growing reluctance of the public to support the high cost of education. Communications and public relations are considered to be helpful tools in explaining school needs and policy to the public. But are the schools in South Dakota making a rational use of these tools? To do so, a public relations-community relations communication policy ls needed. This thesis will evaluate the public relations policy of South Dakota schools--the policy of communicating with the public. It will focus on the school district policy. Included in the discussion …

Fracture Initiation In Viscoelastic Solids, James A. Elsing

Electronic Theses and Dissertations

The subject of this paper is to derive generalized analytical expressions to predict fracture in viscoelastic polymer materials. To aid in understanding behavioral characteristics of viscoelastic materials, a basic background of viscoelastic models and their responses are presented and briefly discussed. Fracture from two types of cracks are considered; the first 1s a penny-shaped crack in a three-dimensional solid and the second is a crack the thickness of the material in a two-dimensional solid. Except for the constants, the same equations describe fracture in both 2-D and 3-D solids. The fracture equations were developed using expressions from Sneddon, Wnuk, Griffith …

Study Of An Automatic Sphygmomanometer System, James B. Morgan

Electronic Theses and Dissertations

A simple and dependable method of automatically measuring blood pressure indirectly would be of great help to the medical profession. An electronic system to implement the measurement of blood pressure using a double cuff method is presented. The scheme is to determine diastolic pressure from the amplitude of the difference signal obtained by subtracting the pulse wave observed in one cuff from that of the other, and to determine systolic pressure from the amplitude of the pulse wave observed in the cuff furthermost from the heart. Although the system is electronically practical, the results obtained from this system show that …

A Study Of The Thematic Importance Of Nine Female Characters Of The English Mystery Plays, Linda Lee Boyd

Electronic Theses and Dissertations

As indicated by the title and by the large proportion of pages devoted to the subject, transformation of variables is the primary topic of this thesis. The transformation of partially overlapping, correlated, two-dimensional, Gaussian distributed random variates to partially overlapping, independent, one-dimensional, Cauchy distributed random variates involves a reduction in dimensionality by one. Consequently, the equation defining the receiver is simplified, and the expressions for predicting the classification error are easier to formulate. The equation required to effect this transformation is z=Y₁/Y₂ , where Y₁ , Y ₂ are the standardized correlated Gaussian variates and z …
