Describes refinements and modifications in the construction of an apparatus to study the kinetics of fast reactions. (CS)

Presents a method for obtaining all mass conservation conditions implied by a given mechanism in which the conditions are used to simplify integration of the rate equations and to derive stoichiometric relations. Discusses possibilities of faulty inference of kinetic information from a given stoichiometry. (CS)

This study was made to determine torque-generating capabilities at two speeds in active young boys and girls for the knee and elbow flexors and extensors. (JD)

Quantitatively investigates the applicability of using the steady state approximation in the kinetics of complex reactions with reversible reactions. (MLH)

Describes a study of the kinetics of the recombination of nitrogen atoms in which concentration-time relations are determined directly by utilizing visual observations of emissions to make gas phase titrations of N atoms with NO. (MLH)

This course is offered in the third quarter of the fourth year of the five-year curriculum in pharmacology. The year includes (1) a 350-hour clinical clerkship, (2) two courses in "Case Studies in Drug Therapy," (3) one course in "Case Studies in Pharmacy Practice," and (4) professional electives. (LBH)

Describes a kinetics experiment in which the student measures both a second-order rate constant and an overall third-order rate constant for the oxidation of benzoin to benzil in an alkaline medium. (MLH)

Describes a laboratory exercise involving methylene blue and L-ascorbic acid in a simple clock reaction technique to illustrate the basic concepts of chemical kinetics. If stock solutions are supplied and each type of experiment takes no more than half an hour, the entire investigation can be completed in three practical sessions of three hours…

Describes a technique that measures the deformation produced in a plastic material by a falling ball in order to compute the ball's kinetic energy. Varying the parameters produces accurate results and gives students a good understanding of the measurement of energy. Combines various mechanical concepts that students have learned separately in…

The loss of carbon dioxide from carbonated beverages provides an interesting case of the combination of equilibrium and kinetic principles. Adding air with a commercial device (the Fizz Keeper) has a negligible effect on various equilibria present but will slow diffusion in the gas space of a resealed bottle, decreasing the rate at which…

Presents an overhead projector demonstration that uses the idea of color fading to demonstrate reaction kinetics and diffusion controlled reaction kinetics. (JRH)

An experiment is performed to measure the relative gas-phase basicities of a series of five amino acids to compare the results to literature values. The experiments use the kinetic method for deriving ion thermochemistry and allow students to perform accurate measurements of thermodynamics in a relatively short time.

This article focuses on postural anticipation and multi-joint coordination during locomotion in healthy and autistic children. Three questions were addressed: (1) Are gait parameters modified in autistic children? (2) Is equilibrium control affected in autistic children? (3) Is locomotion adjusted to the experimenter-imposed goal? Six healthy…

Monte Carlo computational experiments reveal that the ability to discriminate between first- and second-order kinetics from least-squares analysis of time-dependent concentration data is better than implied in earlier discussions of the problem. The problem is rendered as simple as possible by assuming that the order must be either 1 or 2 and that…

Some have argued that the field of kinesiology is losing its vitality because of overspecialization and fragmentation; exercise science scholars are no longer able to find points of convergence with those in kinesiology subdisciplines other than their own. I contend, however, that this is not an accurate portrayal of every subdiscipline.…
