A project was designed to expose students to the complexities of designing an instrumentation and control system for the overall plant design. Project objectives, format, and student activities, accomplishments, and shortcomings are described. (JN)

Obsessive-compulsive disorder (OCD) is a relatively common disorder among children and adolescents, and is associated with increased risk for concurrent and future distress and impairment. Many youth who suffer from OCD go undiagnosed or misdiagnosed, and do not attain appropriate treatment in a timely manner. As a result, researchers have focused…

We describe an inexpensive device for performing capillary electrophoresis (CE) separations with fluorescence detection. As a demonstration of the device's utility we have determined the mass of riboflavin in a commercially available dietary supplement. The device allows for separation of riboflavin in [asymptotically equivalent to] 100 s with a…

Recent progress in wireless and sensor technologies has lead to a new development of learning environments, called context-aware ubiquitous learning environment, which is able to sense the situation of learners and provide adaptive supports. Many researchers have been investigating the development of such new learning environments; nevertheless,…

Discusses two surface techniques: X-ray photoelectron spectroscopy (ESCA) and Auger electron spectroscopy (AES). Focuses on fundamental aspects of each technique, important features of instrumentation, and some examples of how ESCA and AES have been applied to analytical surface problems. (JN)

The new Indianapolis Public School communications system integrates telephone and data communications, security transmission, and energy management within a single network connected by digital microwave radio links. (Author/MLF)

Discusses the relative operating characteristic analysis of signal detection theory as a measure of diagnostic accuracy. Reports representative values of this measure in several fields. Compares how problems in these fields are handled. (CW)

Presents two lists: (1) important considerations for any total chemical analysis and (2) a condensed version that can be used by students to evaluate each analytical procedure. Benefits of using the condensed version (such as seeing that instrumentation is only one of several components of an analysis) are noted. (JN)

Software-driven instrumentation makes measurements that demand a computer as an integral part of either control, data acquisition, or data reduction. The structure of such instrumentation, hardware requirements, and software requirements are discussed. Examples of software-driven instrumentation (such as wavelength-modulated continuum source…

Describes a birefringence apparatus that can be assembled for less than $100 and can be used to measure both the dimensions and dipole moments of many macromolecules. Details are given of the construction and manipulation of the apparatus. (JN)

A microcomputer-controlled system for instrument processing and billing for complex analytical instruments funded by multiple sources in the University of California at Berkeley's College of Chemistry is described and its potential applications in other administrative situations are outlined.

Simple slopes, regions of significance, and confidence bands are commonly used to evaluate interactions in multiple linear regression (MLR) models, and the use of these techniques has recently been extended to multilevel or hierarchical linear modeling (HLM) and latent curve analysis (LCA). However, conducting these tests and plotting the…

How to move science-based labs online has been one of the main obstacles associated with the development of online science programs. In the spring of 2006 and again in 2007, we organized online workshops broadly based around the central theme of Moving the Lab Online. The objective of these workshops was to provide a forum for the exchange of…

A visual tool used to evaluate instructional program performance has been designed by the University of Hawaii Community College system. The tool combines features from traffic lights, blood-chemistry test reports, and industry production control charts, and is labeled the Program Health-Indicator Chart. The tool was designed to minimize the labor…

A method and apparatus for collecting and interpreting eye movement data is described that is both relatively inexpensive and portable. The study lists and describes hardware and software components of a data collection and data analysis system which provides precise information regarding the location, duration, and sequence of eye fixations while…
