Describes an open-ended experiment involving a bioinorganic system that provides the student a direct link between thermodynamics and kinetics. It utilizes a rapid reaction technique and requires one to clearly understand the relationship of experimental observable (absorbance) to a mechanism. (GS)

Describes the production of an electrophoresis apparatus from commonly discarded articles. Outlines paper and gel electrophoresis and its application to the separation of amino acids and intestinal enzymes. (GS)

The purpose of this report is to present and prioritize the major environmental issues associated with the further development of biomass production and biomass conversion systems. To provide a background for this environmental analysis, the basic concepts of the technology are reviewed, as are resource requirements. The potential effects of this…

EIGHTY-FIVE BOOKS AND ARTICLES DEALING WITH DOWN'S SYNDROME (MONGOLISM) ARE LISTED. DATING FROM 1933 THROUGH 1965, THE ITEMS CITED FOCUS ON BIOCHEMICAL AND GENETIC FACTORS AS WELL AS THE DEVELOPMENT OF THE MONGOLOID CHILD. (JD)

The second edition of the Toxic Substances List, containing some 13,000 entries, is prepared annually by the National Institute for Occupational Safety and Health (NIOSH) in compliance with the Occupational Safety and Health Act of 1970. The purpose of the List is to identify all known toxic substances but not to quantitate the hazard. The List…

Results of a 1968 pilot study of the nutritional status of Mexican American preschool children in East Los Angeles and San Diego are reported in this document. Questionnaire data collected from mothers of preschool children are presented in terms of a description of families, prenatal care, clinical examinations, dietary intakes, and biochemical…

A clinical and genetic analysis was made on the basis of 52 families: 27 were from reading clinics where at least one child in the family had been diagnosed as having a reading disability; 25 were families of children selected from a third-, fourth-, or fifth-grade class on the basis of having average or above-average IQ and achievement. Through…

Describes a chemistry project in which lichens are identified by the analysis of the phenolic substances that they biosynthesize. (MLH)

Describes two tests, T-4 and T-3, for hypothyroid based on the binding of the hormones by proteins. The tests were performed in courses for physicians, clinical chemists, laboratory technicians, and undergraduate science students by the individuals involved and on their own sera. These tests are commercially available in kit form. (GA)

Presents a literature review of wastes from the fermentation industry, covering publications of 1976-77. This review focuses on: (1) alcoholic beverage production; (2) pharmaceuticals and biochemicals production; and (3) biomass production. A list of 62 references is also presented. (HM)

Describes how to determine heats of adsorption by means of gas-solid chromatography. Explains the measureable variables involved, the relationships among them, and the graphs to be drawn. (GA)

Describes a method for teaching the technique of nearest-neighbor frequence analysis (NNFA) for testing the fidelity of template DNA replication. (Author/BB)

A FORTRAN program is described which simulates point-substitution mutations in the DNA strands of typical organisms. Its objective is to help students to understand the significance and structure of the genetic code, and the mechanisms and effect of mutagenesis. (Author/BB)

Discusses some basic principles regarding why a certain inorganic element (compound) is specifically required for a certain function in biological systems. (HM)

Reported here are brief descriptions of a common grading and scaling formula for large multi-section courses, an ion exchange amino acid separation and thin layer chromatography identification experiment, a conservation of energy demonstration, a catalyst for synthesizing esters from fatty aids, and an inexpensive method for preparing platinum…
