Presents a practical exercise that enables students to measure flux control coefficients in a metabolic pathway in vitro, to verify the summation property, and to compare the differences in the distribution of these coefficients in different steady states. Discusses background, materials, methods, and results of the activity. (CW)

Addresses the development of innovative skills in future engineers and the factors that promote and inhibit change. Describes two theoretical perspectives which deal with some of the factors affecting individuals and groups when confronted with the possibility of radical change. (TW)

Cites the public image problem of field biologists and systematists. Discusses systematics and natural history including species variation, ecology, management of organisms and appreciation of nature. Describes widespread fallacies which downplay the importance of field biology and suggests ways to improve its image. (CW)

Argues that universities are failing to prepare students for responsible citizenship in a world being rapidly changed by biotechnology. Calls for bringing together biology and the social sciences in more core courses. (TW)

Discusses a single pattern formation mechanism that could underlie the wide variety of animal coat markings found in nature. Presents the results of a mathematical model for how these patterns may be generated in the course of embryonic development. (CW)

Discusses the present state of engineering education in Europe and attempts to compare the different educational systems. Gives views on how to develop engineering education in Europe and how to organize collaboration between universities and their centers of excellence. Discusses the role of the European Society for Engineering Education. (CW)

Gem and mineral shows are excellent nontraditional opportunities for community education and outreach by geology teachers. Discusses initial club contacts, displays, shows, and the advantages of show participation to academic geologists. (CW)

Announces and presents highlights from a new report from NSF "Proposal Review at NSF: Perceptions of Principal Investigators." This report presents the results of a 1986 NSF survey of 14,000 applicants from academic institutions whose proposals for research support had been awarded or declined during 1985. (CW)

Examined the feasibility of using two microcomputer simulations to improve preservice elementary teachers performance in the formation and testing of hypotheses. Considers the effects of mode of computer instruction and cooperation on the acquisition of skills. (CW)

Reviews topics from editorials in "Graduating Engineer" in the 1980's. Discusses the state of the economy at present, as well as new technology and jobs in engineering fields. Cites manufacturing excellence as a present theme in the engineering field. (CW)

Describes some of the common principles underlying the operation of the cortex in an effort to understand the human brain. Discusses the structure of the cortex, its specific areas, and its map-making abilities. Describes some of the recent discoveries about brain operation, development and functioning. (TW)

Describes the construction of an inexpensive apparatus for separating proteins by polyacrylamide gel electrolysis in the presence of sodium dodecyl sulphate. (TW)

Suggests a new experiment to study the genetic material of eukaryotes. It is based on the rapid growth and interest of the research on chromatin. (TW)

Discusses the use of the FT-IR spectrometer in analyses that were previously avoided. Examines some of the applications of this spectroscopy with aqueous solutions, circular internal reflection, samples with low transmission, diffuse reflectance, infrared emission, and the infrared microscope. (TW)

Illustrates the 29 steps involved in the development of a model of a coordination polyhedron that represents the hexagonal closest packed structure. Points out it is useful in teaching stereochemistry. (TW)
