Describes a semi-automatic viscometer which incorporates a microprocessor system and uses optoelectronics to detect flow of liquid through the capillary, flow time being displayed on a timer with accuracy of 0.01 second. The system could be made fully automatic with an additional microprocessor circuit and inclusion of a pump. (Author/JN)

Describes modification of a gas viscometer to produce a low cost instrument with high precision and safe design. Three tungsten electrodes are mounted in the viscometer using graded glass seals and a ball trap is inserted between mercury reservoir and all external stopcocks. Also describes modifications in experimental procedures. (Author/JN)

Presents a description of the National Center for Atmospheric Research, a center where scientists pursue research interests, where research facilities, too large and expensive for any one institution to maintain, are housed, and where unified planning for research is made in response to national and international concerns. (SA)

Described is a project SIINC (Scientific Instrumentation Information Network and Curriculum), a three year pilot program to test the feasibility of developing a computer-based system for accessing information vital to users of chemical instrumentation. Project SIINC fills the gap between conventional sources of instrumental information and…

Describes recent developments in instrumentation for clinical chemistry in the areas of general chemistry, immunoassays, urinalysis, electrophoresis, chromatography, and trace metal analyses. (CS)

Describes the continuing education program for clinical chemistry instrumentation training established at The College of Staten Island, New York. A course consisting of 14 sessions is outlined and discussed. (CS)

Spectroscopic studies on solutions and x-ray diffraction work on crystals lead to the conclusion that the Metrogen of the pyrimidine ring is preferentially protonated. The correct monoprotonated structures of thiamine and its 4-amino-pyrimidine synthetic precursor are presented. (BT)

Following a delineation of thermoluminescence from a historical perspective and a qualitative description of the process, a treatment of the kinetic process based on a simple model is presented. This treatment model is adequate for the purpose of identifying the essential requirements in instrument design. (BT)

Concepts used in the design of a Dallas school make the building an integral part of the instructional program. These concepts include instrumented resource consumption, wind powered electrical generating capabilities, solar powered domestic hot water system, grey water cycling and sampling capabilities, and mechanical systems monitoring.…

Focuses on recent research on currents and eddies of the earth's oceans. Special emphasis is given to instrumentation involved in studying the oceans. (SA)

Describes the Teacher Orientation to Science Instruction (TOTSI) instrument, which comprises a set of statements on eight characteristics of science teaching. TOTSI evaluates teacher assumptions to indicate what type of curriculum best suits the teacher's abilities and preferences. (MLH)

This article discusses the development and field test of an instrument, A Survey of Student Personnel Objectives, that can be used to evaluate whether a college or university's student personnel program is achieving its objectives. (Author)

Discussed is an analytical technique that uses photons from lasers to resonantly excite an electron from some initial state of a gaseous atom through various excited states of the atom or molecule. Described are the apparatus, some analytical applications, and the precision and accuracy of the technique. Lists 26 references. (CW)

Presented are system concepts with examples of various vendor approaches for implementing laboratory local area networks. (CW)

Attempts to identify and characterize patterns of expert teaching practice as they occur in context, and to confirm these patterns through processes of verification. Observes teacher Dorothy DeLay in her studio, documenting her teaching through notes, audiotapes, and contextual artifacts. Discusses DeLay's theory of proximal positioning in…
