Polarography, James Mccarty

Honors Theses

Jaroslav Heyrovsky invented the technique of polarography about 1920 at Charles University in Prague. With proper use one can obtain both qualitative and quantitative analyses of solutions of electro-oxidizable or electro-reducible substances at concentrations.

The key part of a polarography is the dropping mercury electrode. This consists of a fine bore capillary tube connected to a large reservoir of mercury. Each tiny drop which falls from the capillary has approximately the same surface area and takes about the same time to form and fall. The greatest advantage is that each drop is actually a new electrode, and there is consequently …

An Introduction To Linear Programming, Lana Sue Legrand

Honors Theses

This paper represents a study of the text An Introduction to Matrices, Vectors, and Linear Programming. It is composed chapter by chapter taking the more important statements, definitions, and theorems from each and working out exercises to illustrate their meaning. Other exercises were worked in the course of the study than are included in this paper but these were selected as brief illustrations of the type of problems that were worked.

Special Studies In Biochemical Instrumental Methods, Parvin Waymack

Honors Theses

Two useful methods of biochemical analysis are infrared and ultraviolet spectroscopy. The occurrence of absorption bands in the infrared region can be predicted for some of the simpler molecules. Theoretically, in order for a molecule to absorb radiation it must possess a vibrational or rotational frequency the same as that of the electromagnetic radiation, and a change in the magnitude and/or direction of the dipole moment must take place. The change in dipole moment may be caused by asymmetrical vibration or asymmetrical rotation of the molecule.

Mathematics And Logic, Janet Moffett

Honors Theses

Mathematics is interested in the methods by which concepts are defined in terms of others and statements are inferred from others. It therefore uses a primarily deductive form of reasoning. It is almost impossible to distinguish where logic leaves off and mathematics begins. "... logic is the youth of mathematics and mathematics is the manhood of logic." Mathematics starts from certain premises and, by a strict process of deduction, arrives at the various theorems which constitute it.

In order to understand the congruence of mathematics and deductive logic, one must understand the principles of each and the relation between them. …

Chronopotentiometry Of Metals, Lana Sue Legrand

Honors Theses

For a long time now the general characteristics of potential-time curves in constant current electrolysis have been known and studied. In 1901 Sand derived his equation giving a relationship for the transition time, providing that the solution is unstirred and linear diffusion is the controlling factor.

Calcium Carbonate Determinations, James Phelan

Honors Theses

Calcium compounds are abundant in nature. The carbonate ion may exist in many varieties, such as aragonite and limestone. Of major importance in the following discussion, however, is calcite. Calcium carbonate may well be of animal origin, prime examples being sea shells, coral, and chalk. Dolomite, on the other hand, is a double carbonate of calcium and magnesium. Calcium in natural waters exists mainly as a bicarbonate, Ca(HCO3)2, which is temporary hardness, or as a sulfate, which is permanent hardness.

From determinations made periodically (every two weeks) since August 1966, a decrease has been found in the calcium content as …
