The Radiation And Directive Characteristics Of Antenna Arrays
(1939-04-01)An understanding of the mechanism by which energy is radiated from an antenna is the purpose of this thesis. It was generally believed, until 1920, that radio waves traveled in an ever expanding circle, like the ripples ... -
A Quantitative Determination Of Iron Employing Gooch Crucibles
(1948-04-01)Generally iron ores are analyzed for their iron content by dissolving accurately weighted samples in hydrochloric acid, oxidizing the iron to the ferric condition, and precipitating it with freshly distilled or filtered ... -
The Food Analysis Of The Prickly Pear Cactus (Opuntia Polycantha)
(1950-04-01)The primary purpose of this thesis was to perform a food analysis of the prickly pear cactus (Opuntia Polycantha) in order to ascertain the percentage of the six basic constituent groups; (1) water or moisture, (2) fat, ... -
The Electromagnetic Wave Equations of James Clerk Maxwell
(1951-04-01)The purpose of this paper is to give an elementary presentation of Maxwell's Wave Equations. It is not the aim of the author to present any new information and the sources of this paper are as follows s The historical-data ... -
The Determination Of The Solubility Of Silver Ortho-Nitrobenzoate
(1955-04-01)The object of this investigation was to determine the solubility of the silver salt of ortho-nitrobenzoic acid in pure water by potentiometric and conductiometric methods. An extensive search into the literature yielded ... -
A Theoretical Interpretation Of Polarographic Studies Of The Cadmium Complexes of Thiourea and Methylthiourea In Dioxane-Water Mixtures
(1956-04-01)The purposes of this work ares a) to determine the stability constants for complexes of thiourea and methylthiourea with cadmium (II) ion by applying a definite correction factor to the best existing determination (1); and ... -
A Colormetric Study Of Alizarin Red S
(1957-04-01)Spectrophotometry refers to the relative measurement of radiant energy or radiant flux as a function of wavelength. It applies not only to visual measurements, but also to photographic and photoelectric methods of measurement ... -
Liver Function Tests In Relation To Liver Disease
(1958-04-01)No other one organ has as many functions to perform in the body as the liver. It is this fact which necessitates an accurate and practical evaluation of the many liver function tests in use today. So many new tests have ... -
The Determination Of Selectivity Or Specificity Of 2,4 Dichlorophenoxyacetic Acid, N-N Dimethylparaphenylazoanaline, And Symmetrical Diphenylthiourea As Potential Analytical Reagents
(1959-04-01)Many organic compounds have been found to form stable complexes with certain metal ions. A complex may be defined as a compound in which the covalency of the element is greater than its valency, or those compounds of an ... -
Comparative Chelate Stabilities By Potentiometric Titrations
(1959-04-01)A chelate is a particular type of a complex or coordination compound. When a metal ion occupies two or more places on an electron donor to form a ring, it is said to form a chelation compound, the electron donor being ... -
A Qualitative Analysis Of Electrical Discharge In Air
(1962-04-01)The purpose of this paper is to present the fundamental ideas of the gaseous electrical discharge and to experimentally verify those presented ideas. Chapter I deals with the theoretical description of the discharge in a ... -
The Effect Of Temperature On the Standard Oxidation-Reduction Potential Of The Ferricyanide-Ferrocyanide System
(1966-04-01)It is the purpose of this .investigation to determine the temperature dependence of S°, that is, 3° as a function of the variable T. Prom this data an entropy difference can be obtained for the total cell reaction (2). The ... -
A Study Of The Synthesis Of Polyvinyl Alcohol
(1967-04-01)Polyvinyl alcohol is a high molecular weight polymer whose repeating unit is CH2-CHOH. From this the expected monomer from which polyvinyl alcohol would be produced is vinyl alcohol, CH2=CHOH, however, vinyl alcohol does ... -
The Reversible Denaturation Of Oxidized Cytochrome c At pH 2.9
(1967-04-01)The physico-chemical study of biological molecules is a rapidly expanding area of investigation which allows an examination of the relation of biological process to molecular structure. The structural relationship of DNA ... -
Optimal Conditions For The Enzymatic Reaction Lactic Acid Dehydrogenase / Lactate
(1970-04-01)Enzymes are vital for metabolic processes in any living organism. If the function of enzymes is restricted or their concentration changed, drastic changes may come about within the organism. Enzymes act as catalysts to ... -
The Effeet of Various Levels of DDT on the Carbohydrate Metabolic Process of Rats
(1970-04-01)Much controversy has arisen in the 1950’s and 196O’s over insecticides and their effect on soil, plants, and creatures of the earth. This controversy, brought to the attention of the general public by Rachel Carson’s Silent ... -
Philosophical Concerns of Chemistry, Physics and Mathematics
(1972-04-01)This thesis is written in the hope of providing a conspectus of the philosophical concerns of the intermingling branches of chemistry, physics and mathematics. Different perhaps are their names and some of their goals, hut ... -
