Reports on findings of research done by Nolan Information Management Services concerning availability of microcomputer software for libraries. Highlights include software categories (specific, generic-database management programs, original); number of programs available in 1982 for 12 applications; projections for 1983; and future software…

Illustrates the state of the art in pyrolysis mass spectrometry techniques through applications in: (1) structural determination and quality control of synthetic polymers; (2) quantitative analysis of polymer mixtures; (3) classification and structural characterization of fossil organic matter; and (4) nonsupervised numerical extraction of…

Discusses working implementations of artificial intelligence systems for chemical laboratory applications. They include expert systems for liquid chromatography, spectral analysis, instrument control of a totally computerized triple-quadrupole mass spectrometer, and the determination of the mineral constituents of a rock sample given the powder…

Discusses recent developments in the instrumentation and practice of analytical scale operations. Emphasizes detection devices and procedures in gas chromatography, liquid chromatography, electrophoresis, supercritical fluid chromatography, and field-flow fractionation. (JN)

Discusses: (1) rationale for chemical sensors in process analysis; (2) existing types of process chemical sensors; (3) sensor limitations, considering lessons of chemometrics; (4) trends in process control sensors; and (5) future prospects. (JN)

Discusses various topics related to the interfacing of computers, focusing particularly on methods of data collection using instruments. Topics include serial digital connections (examining RS 232C and V.24, physical protocol, electrical protocol, and other areas) and parallel digital connections. (JN)

Discusses how computational errors arise in analysis of data and how they can be minimized. Shows that all computations are subject to roundoff/truncation errors and how such errors are propagated and influence the stability and condition of a reaction. Applications to procedures used in analytical chemistry are addressed. (JN)

Discusses new solid-state transducers, arrays of nonspecific detectors, hardware and firmware computational elements, and other devices that are transforming modern analytical chemistry. Examples in which microelectroic sensors are used to solve 14 problems are included. (JN)

Descriptions of available microcomputer software cover basic software, word processing, database management systems, in-house information retrieval, searching of external online information retrieval systems, in-house library housekeeping, and financial and management software. Checklist of points to consider when acquiring software, 36…

Reviews two basic ways in which microcomputers are being used in school library media centers--administrative or management purposes (circulation control, budget planning, acquisitions processes, staff and student scheduling); and instructive purposes (library skills, drill and practice, problem solving, computer literacy). Three major types of…

Creative uses of Apple II microcomputers in classrooms are described. Projects involved topics ranging across the curriculum, with many involving writing and most using AppleWorks software. (MNS)

Examines capabilities of the computer as a tool for bibliographic instruction; how librarians can utilize the computers; and the effects of microcomputers on bibliographic instruction librarians. Three approaches to writing computer-assisted instruction (CAI) programs (CAI authoring system, special purpose CAI language, general purpose computer…

Focuses on first step in process of implementing library skills instruction through integration with everyday curricular activities of classroom--gathering and evaluating of information about curriculum. Existing curriculum information sources, curriculum mapping, pilot studies testing curriculum mapping feasibility, and implementation of mapping…

Describes technological services provided by regional media centers, which generally serve more than one school district--reservation systems, reference, interactive video, computer-related uses, earth stations, microwave and slow-scan television, audio and video duplication, slide and film reproduction, printing, inspection of films and…
