Although a large number of experiments on aquation kinetics of inert octahedral complexes exist, few exist on the reverse (anation) reaction. Preliminary considerations and laboratory procedures for a kinetic study of the anation reaction are provided. Several pairs of students can complete the experiment in a three-hour period.

Describes an exercise, suitable for use on programmable calculators or microcomputers, to calculate some of the rapidly processing orbits of a mass M near a static black hole star of mass M. (SK)

Describes a one-semester, three-credit hour course integrating the fundamentals of kinetics and the scientific/engineering principles of heterogeneous catalysis. Includes course outline, list of texts, background readings, and topical journal articles. (SK)

Designed for the organic chemist involved in interpreting NMR spectra, basic concepts of chemical shift equivalence and magnetic equivalence in NMR spectrometry are discussed. (CS)

Describes a method, considered appropriate for presentation to undergraduate students in materials science and related courses, for the calculation of cohesive energies of the alkali metals. Uses a description based on the free electron model and gives results to within 0.1 eV of the experimental values. (Author/GS)

The general problem of mass accretion by a drop falling through a cloud of droplets is considered as an exercise in introductory or intermediate mechanics. The kinematic behavior of the falling drop is deduced for a variety of mechanisms of mass accretion, and some special limiting conditions are discussed. (Author/SK)

The use of biological examples in teaching applications of the analog computer is discussed and several examples from mathematical ecology, enzyme kinetics, and tracer dynamics are described. (Author/GA)

This article describes the distribution of mass in a hand-held object as a fundamental but unrecognized contributor to the sensation one receives from the object. Experiments producing fractions for human sensitivity are given. (SA)

Describes a nineteenth century paper by Reynolds on his experiments with the tension that a column of liquid could sustain, and compares Reynolds work with some of the other related work published in French journals at that time. (GA)

Constructs a theory, using Aristotelian lines of thought, to explain Galileo's assumed experimental results that all bodies fall at the same rate, ragardless of their weight. (GA)

Explains how to demonstrate the fundamentals of one dimensional kinematics such as Newton's third law of motion, and collision between bodies, using simple materials of marbles, strings, sticky tape, drinking straws, and rubber bands. (GA)

Describes an experiment that utilizes polarimetry to measure mutarotation of glucose and nmr spectroscopy to identify the structures of reactants and products of biochemical reactions. (MLH)

Discusses the stability of the three-electron bond from a thermodynamic and kinetic standpoint using molecular orbital theory. (MLH)

Presents a unit on chemical reaction kinetics that consists of a predemonstration activity, the demonstration, and a set of postdemonstration activities that help students transfer the concepts to actual chemical reactions. Simulates various aspects of chemical reaction kinetics. (JRH)

The occurrence of dyskinetic movement disorder and its co-occurrence with stereotypic behavior among adults with mental retardation were studied in 98 adults with mental retardation. Results indicated that stereotypic movement disorder was associated with increased dyskinesia scores and that dyskinesia and stereotypy may be related by common…
