Automated science curriculum : an experimental science program

Creator:: Hutchinson, John Stuart
Abstract:: Purpose: The purpose of this study was to determine statistically the effects of an automated science curriculum on the science learnings of eighth grade students. This curriculum involved the use of Keysort cards as a flexible handbook for teachers and included in the directions for use a teaching method which...

Solid-vapor equilibria of hafnium and zirconium tetrachlorides

Creator:: Landsberg, Arne
Abstract:: The chemically similar elements hafnium and zirconium occur together in nature. Because of their very dissimilar nuclear properties it is of commercial importance to separate them for use in the atomic energy field. One or more of the steps in the separation and purification processes presently used involve the volatile...

Multiple forms of carboxylesterases in the green bean (Phaseolus vulgaris L.) and pea (Pisum sativum L.)

Creator:: Veerabhadrappa, Patnagere Siddaveera Sheety
Abstract:: Esterase activity of an aqueous extract of the green bean was separated into fourteen bands, while aqueous extracted pea esterases revealed seven bands, by polyacrylamide-gel electrophoresis. The fourteen bands of bean esterase activity formed three groups; slow, intermediate and fast moving. α-Naphthyl acetate, propionate, and n-butyrate and AS naphthol acetate...

Radiotracer methodology in biological science

Creator:: Willis, David L.
Abstract:: The use of radioactive isotopes as tracers in biological systems has become widespread since the close of World War II. Proper use of radiotracers requires a fundamental understanding of the physical nature of radioactivity, the characteristics of ionizing radiation, and the various methods available for measuring radioactivity. More importantly, the...

The effect of freezing and freeze-drying on the physico-chemical changes in Northwest strawberries

Creator:: Rao, Akkinapally Venketeshwer
Abstract:: Preservation of food by freezing is a common method of processing. Of relatively recent origin is the freeze-drying method. This method has several advantages over other methods of preservation, but is not free of problems, one of which is the maintenance of appearance and texture. In the present study, the...

Replica-plating and computer analysis for rapid identification of microorganisms in seafoods

Creator:: Corlett, Donald A.
Abstract:: A method was devised and tested for rapid and quantitative identification of microbial flora in fresh seafoods. The rapid identification of large numbers of isolates was made possible by (1) a simplified identification scheme established by reference culture studies and from the known reactions of microorganisms reported in the literature,...

Flavor chemistry of irradiated milk fat

Creator:: Khatri, Lakho Lilaram
Abstract:: Increasing interest has been shown in the irradiation sterilization and irradiation pasteurization of foods, but problems of off-flavors and odors are still unsolved, especially in the case of dairy products. From the flavor chemistry point of view, milk lipids are very highly susceptible to irradiation effects. Therefore, this investigation was...

Malonaldehyde : certain chemical and biological properties

Creator:: Crawford, David Lee
Abstract:: Malonaldehyde, a three carbon dialdehyde, is one of the numerous carbonyl compounds associated with oxidative deterioration of food lipids. It is assumed to be formed as a product of lipid autoxidation occurring according to the generally accepted free radical mechanism. This compound is of great interest because of its potential...
