Discussed is wavelet theory, which provides ways to rearrange data to reveal features of a physical or mathematical system which might otherwise be hidden. This theory is compared to fourier analysis and the advantages of wavelet theory are stressed. Applications of this technique are suggested. (CW)

Described are methods which can be used by developing countries to affordably obtain the energy without ruining the environment. The approaches mix efficient end-use technologies with modest increases in generating capacity. (CW)

Procedures for duplicating fossil raindrop impressions are presented. The use of modern and fossil imprints as the basis for qualitative and quantitative lessons in the interpretation of ancient sedimentary features is discussed. (CW)

Discussed are positions on the topic of creationism. The dichotomy between science and religion is analyzed. Middle positions are highlighted and the fundamental issues clarified. Examples that illustrate historical changes in scientific thought are included. (KR)

Described is a study which was developed to find the proportion of cross-dominance in young adults. Procedures and statistical tests are discussed. The tasks used in the assessment of cross-dominance are described. Results indicated that all persons suffered from some cross-dominance. (CW)

Discussed are applications of biochemistry. Included are designed drugs, clever drugs, carcinogenic structures, sugary wine, caged chemicals, biomaterials, marine chemistry, biopolymers, prospecting bacteria, and plant chemistry. (CW)

Discussed is the importance of valence bond theory on the quantum-mechanical theory of chemical structure and the nature of the chemical bond. Described briefly are early VB theory, development of VB theory, modern versions, solid-state applications, models, treatment in textbooks, and flaws in criticisms of valence bond theory. (KR)

The use of actographs for studying animal activity is discussed. Described are running recorders for rodents, perching and feeding recorders for birds, and tilting box recorders for studying the movement of reptiles, amphibians, and arthropods. (CW)

Summarizes the report on undergraduate education in biology published by the National Science Foundation. Discusses the problems and recommended solutions for each of three areas: laboratories and course development; enhancing the quality of teaching; and recruitment and retention of students. (YP)

Examined are the effects of testing on the achievement of students using self-instructional materials to learn science process skills. Results indicated that frequent quizzes did not differentially affect process skill acquisition. (Author/CW)

Presented is a simple, unified approach to chemical nomenclature which employs the distinction between the terms chemical substance and chemical species. The classification of matter and chemical nomenclature are used as examples to illustrate this scheme. (CW)

This volume includes 303 entries of programs on engineering and engineering technology; 239 entries on engineering programs, and 64 entries on engineering technology programs. The information includes the school name and address; school profile; admission information including student expenses and financial aid; graduation requirements; and…

The procedures, data analysis, and applications of this laboratory activity are detailed. An example of the results obtained is provided. Sources of the tadpoles and their treatment are discussed. (CW)

Presents a didactic model to improve the teaching/learning process in the representation of Lewis structures. Places special emphasis on the calculation and reduction of formal charges, and in the representation of molecules in which the central atom has expanded its valence shell. (MVL)

Highlights several analytical techniques that are being used in state-of-the-art clinical labs. Illustrates how other advances in instrumentation may contribute to clinical chemistry in the future. Topics include: biosensors, polarization spectroscopy, chemiluminescence, fluorescence, photothermal deflection, and chromatography in clinical…
