The Association of American Medical Colleges presents the results of their Annual Salary Questionnaire for medical school faculties for the fiscal year 1971-72. Ninety-five schools submitted returns and salaries of 4,930 basic scientists and 11,941 clinical scientists are reported in the survey. The areas covered include strict full-time faculty…

This module is intended to help engineers evaluate the relative health risks from pathogens at land treatment sites versus conventional waste treatment systems. Among the topics considered are the following: (1) the relationship between survival time of pathogens and the chance of disease transmission to humans; (2) the factors that favor survival…

This unit, intended for students in grades eight or nine, is a revised version of ED 053 990. The teacher's guide lists the aims of the unit, behavioral objectives, suitable references and audio-visual aids, required apparatus and materials, and provides teaching notes for each activity, including comments concerning microbiological techniques.…

Describes several microbiology labs and the maintenance of a bacteria bank for use by all schools in a district. (LS)

Presents a literature review of bacterial pathogens that are related to water pollution, covering publications from 1976-77. This review includes: (1) bacterial pathogens in animals; and (2) detection and identification of waterborne bacterial pathogens. A list of 129 references is also presented. (HM)

For teachers in search of an easily obtainable, readily dissectable, and unique living specimen to arouse the interest of their students and illustrate important biological principles, lichens are the perfect selection. Background information and experiments on lichen anatomy, physiology, and chemistry are given. An appendix gives culture media.…

The technique of listing behavioral objectives for a teaching syllabus is briefly described. A list of 38 objectives is given for a previously described practical microbiology course and student reaction to them is discussed. Clearly written objectives are considered a powerful tool for the teacher, benefitting both teacher and student. (Author/MA)

Presents a series of experiments built around the bacteria found in the intestinal tract of formalinized rats as a model for discussing microbial ecology. Describes methods of examination of intestinal content, student tasks, and discussion questions; also gives a challenge problem to solve.

Describes: basic features of pollen grains (shapes, apertures, layering of wall, exine sculpturing); strategies for pollination (anemophily--wind transported, zoophily--animal transported); and the structures specialized for each process. Gives instructions for using scanning electron microscope photographs and for collecting, identifying, and…

Presents classroom activities for teaching microbiology at the elementary and secondary levels. Activities demonstrate the existence of the microbial world, types of microbes, and their growth needs and effects in nature. (MLH)

Describes several experiments, suitable for secondary school biology classes, using the bioluminescent marine bacterium, Achromobacter fischeri. (JR)

Described is a method of simulating the formation of a DNA distribution, on which statistical results and experimentally measured parameters from DNA distribution and percent-labeled mitosis studies are combined. An EAI-680 and DECSystem-10 Hybrid Computer configuration are used. (Author/CS)

Discusses biotechnology in terms of its potential and the bottlenecks encountered in the course of development. Topics/issues addressed include: biotechnology definitions; research prospects; raw material constraints; co-ordination/financial support; training; industry/university conflicts; possible risks; and legal protection involving living…

Describes a lysozyme assay for use in the biology classroom to teach enzymology. Provides background information, materials and methods, sources of lysozyme, and evaluation of the assay. (DS)
