An Experiment On The Effects Of Humidity On Screen-Process Stencils, Thomas R. Bresadola
An Experiment On The Effects Of Humidity On Screen-Process Stencils, Thomas R. Bresadola
Electronic Theses and Dissertations
Quality control is management, it is a way of thinking. To function properly, it cannot be isolated in one section of the plant, but rather it must permeate the entire climate of the plant. Management is control through decision making. Decision making requires accurate and complete information, if errors are to be avoided. The quality of the information on which decisions are based determines the quality of the decisions themselves. Quality may be defined by stating what is acceptable, and what is not acceptable. Quality used in this sense varies greatly from plant to plant. The company printing slogans on …

Replacement Of Protein With Amino Acids In Diets For Laying Hens And Turkey Poults, Edwin J. Novacek
Electronic Theses and Dissertations
Low protein diets were formulated for experiments with laying hens and turkey poults. The diets were supplemented with equal amounts of protein and different feedstuffs while maintaining equal calculated levels of selected amino acids. Single trails were also reported for factorially applied amino acid supplements to turkey starter and cage-layer diets. The three-year studies indicated that a typical corn-soy layer diet diluted with glucose monohydrate to 9.4 percent protein was deficient in methionine, lysine and tryptophan. Attempts to further improve the rate of egg production by additional supplements of arginine, isoleucine, valine, or diammonium citrate were not successful. The low …

I. Low Temperature Deoxygenation Reactions Involving Dihalophosphites. Ii. The Mechanism Of Nucleophilic Substitution At Phosphorus : Evidence For An Snl(P) Mechanism, Henry Liland Horten
Electronic Theses and Dissertations
Part 1: An intermediate species in the Arbuzov ring opening of bicyclic phosphites was discovered. Addition of chlorine or bromine to l-alkyl-4-phospha-3, 5, 8-trioxabicyclo(2. 2.2) and octane at low temperatures produced a solid P, P-dihalo phosphonium intermediate which ring-opened at room temperature to form the 5-alkyl-5-halomethyl-2-halo-2-oxo-1, 3, 2-dioxaphosphorinan. The intermediate was found to deoxygenate alcohols, ethers, aldehydes and ketones to produce the bicyclic phosphate and the various alkyl halides. The intermediate also cleaved acids and esters to form the acyl halides. The mechanism of the deoxygenation reaction was proposed to involve a type of SNi pathway that included …

An Infrared Investigation Of Triphenylphosphine, Triphenylphosphine Oxide, And Some Of Their Complexes, Lynne L. Haas
An Infrared Investigation Of Triphenylphosphine, Triphenylphosphine Oxide, And Some Of Their Complexes, Lynne L. Haas
Electronic Theses and Dissertations
The infrared spectra of triphenylphosphine, triphenylphosphine oxide, and their complexes have been studied by several groups of workers. These spectra are helpful in determining the modes of complex formation and elucidating structural aspects of the complexes. Although many of the bands can be attributed to phenyl modes, the areas between 1200 and 1050 cm-1 and between 800 and 700 cm-1 contain bands which arise from bonding within the ligand (phosphorus-phenyl linkages) or bonding of the ligand to a metal ion (phosphorus-metal linkages in triphenylphosphine complexes and oxygen-metal linkages in triphenylphosphine oxide complexes.) Work with triphenylphosphine at South Dakota …
