This manual describes the Caregiver Language Observation Instrument, a device useful for observing the language behavior of caregivers in infant day care settings. Eleven categories of language behavior are recorded: approval, disapproval, cautioning, soothing, talking to, questioning, labeling, elaborating, singing, directing, and imitating. The…

The role analytical instrumentation performs in the surveillance and control of the quality of water resources is reviewed. Commonly performed analyses may range from simple tests for physical parameters to more highly sophisticated radiological or spectrophotometric methods. This publication explores many of these types of water quality analyses…

Jobs in radio arts, from serviceman to station engineer, are easier to get if one has a recommendation of the U.S. Government in the form of a license from the Federal Communications Commission (FCC). This study guide for FCC radiotelephone licenses is designed to thoroughly prepare the applicant for any radiotelephone exam and to serve as a…

This instrument for describing writing is designed for use by teachers and researchers at the secondary and college levels. The two main sections are an outline of the complete instrument and the instrument itself. Various categories of the instrument can be used to describe general, descriptive, and explanatory prose; other categories are related…

The Coast Guard utilizes a number of monitoring detectors, sensors, and techniques to find, recover and identify oil spills. Discussed in this article are in-situ and airborne sensors, systems developed to provide clean-up capability such as air deployable anti-pollution transfer system (ADAPTS), and techniques which will determine the source of a…

Provides descriptions, including prices and features, of many of the scientific instruments displayed at the 1976 Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy. (MLH)

Discusses the scientific and financial aspects of large instrument sharing in natural science areas from the point of view of instrument centers, users and funding agencies. Concludes that effective actions, with well-defined goals, must be implemented to solve the problems of instrument sharing. (GA)

The procedure and sampler described permits detection of less than 50pg of one polychlorinated naphthalene (PCN) isomer. The method uses gas chromatography-mass spectrometry. The PCNs are collected on a glass fiber filter and two polyurethane foam plugs and extracted with toluene at 25 degrees Celsius. (BB)

This method of image enchancement and real-time imput of 3-D microscopic objects into an optical pattern recognition system is designed to identify and count diatoms as a means of water pollution assessment. The method consists of directing a low-power laser beam into a microscope to produce a coherent image of the specimen. (Author/BB)

The influence of new medical instruments is large but not always easy to interpret. However, this author attempts to do just that. Included topics are: general trends, computers, economic considerations, and regulatory constraints. (BB)

Discusses two applications of Laboratory Information Management Systems (LIMS) in the undergraduate laboratory. They are the coulometric titration of thiosulfate with electrogenerated triiodide ion and the atomic absorption determination of calcium using both analytical calibration curve and standard addition methods. (JN)

Provides an overview of Laboratory Information Management Systems (LIMS) and their implementation in undergraduate analytical laboratories. Basic components of a well-constructed LIMS system, hardware considerations, and software considerations are addressed. (JN)

Presented is a three-hour instrumental analysis experiment which allows study of software data-handling methods. These methods include sampling, boxcar averaging, smoothing, ensemble averaging, and digital filtering. Use of the program should provide students with a better idea of advantages and disadvantages of using such software data-handling…

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…

Reports on the status of nuclear magnetic resonance (NMR) from theoretical and clinical perspectives, reviewing NMR theory and relaxation parameters relevant to NMR imaging. Also reviews literature related to modern imaging strategies, signal-to-noise ratio, contrast agents, in vivo spectroscopy, spectroscopic imaging, clinical applications, and…
