Paper describes a method of estimating the theoretical area of undergraduate laboratories and associated ancillary accomodation required by departments in relation to specific levels of student enrollment and course teaching structures. (Author)

A low-cost tensile testing machine was built for testing polymeric films. This apparatus also allows for tear-strength and flexural tests. The experimental results, obtained from common-use materials, selected by the students, such as plastic bags, illustrate important aspects of the mechanical behavior of polymeric materials. Some of the tests…

Reports a modification of a simple method previously described for determining enthalpies of sublimation and comments on some of the method's inherent limitations. (Author/GS)

Described are applications of computer data acquisition to three laboratories in materials science at the United States Naval Academy. In each laboratory, data are input to a minicomputer, scaled using previously obtained and stored calibration factors to convert the transducer signals to load, displacement, temperature, etc., and then stored on…

PART ONE OF THIS BULLETIN PROVIDES HELP IN THE TWO CRITICAL AREAS OF MASTER TAPE PREPARATION AND DUPLICATION. SUPPLEMENTED BY NUMEROUS PHOTOGRAPHS AND DIAGRAMS OF EQUIPMENT AND DUPLICATION TECHNIQUES, THE BULLETIN DESCRIBES MASTER PROGRAM DUPLICATION USING LANGUAGE LABORATORY EQUIPMENT, A PROFESSIONAL MASS DUPLICATOR, A TAPE RECORDER, A RECORD…

Reviews legislation and controls in effect, and needed, to reduce the hazards of violent reactions in the uncontrolled mixing of incompatible chemicals. (SL)

Describes an apparatus and experimental procedure for quantitatively evaluating the activation energy associated with annealing color centers in glass. (MLH)

The experiment described here involves simultaneous monitoring of pH and NMR chemical shifts during an aqueous titration of alpha- and beta-alanine. This experiment is designed for use in an undergraduate biochemistry course. (MR)

Describes techniques for studying hand specimens of polished rock slabs. (SL)

Presented is the development of a simulation model of the facultative water transfer mechanism of the mammalian kidney. Discussion topics include simulation philosophy, simulation facilities, the model, and programming the model as a teaching aid. Graphs illustrate typical program displays. A listing of references concludes the article. (MA)

Discusses four different methods for measuring self-inductance based on the definition of inductance, the alternative definition, phase difference and LC resonance. Provides circuit diagrams and typical oscilloscope traces. (YP)

Elements of the development of a robotics and automation laboratory are discussed. These include the benefits of upgrading current staff, ways to achieve this staff development, formation of a robotics factory automation committee, topics to be taught with a robot, elements of a laboratory, laboratory funding, and design safety. (CT)

Previously described a class experiment which employs the hydraulic analog to represent systems of first order reactions in batch reactors. The hydraulic experiments are extended to represent reaction systems with nonlinear systems. (JN)
