Discusses expanding user community seeking access to synchrotron radiation sources, properties/sources of synchrotron radiation, permanent-magnet technology and its impact on synchrotron radiation research, factors limiting power, the density of synchrotron radiation, and research results illustrating benefit of higher flux and brightness. Also…

Suggests that the appropriateness of a methodology for the study of adult literacy programs be determined by assessing the extent to which the methodology speaks to the information needs and context complexity involved. (JOW)

Uses an example of literature error to illustrate several principles often difficult to present to chemistry students. Indicates how the significance of previously reported experimental results is changed when previously reported assumptions are replaced by an alternative set of assumptions leading to a self-consistent interpretation of the…

Describes a group experiment demonstrating the use of conductivity measurements in the application of kinetic methods of nucleophilic aliphatic substitution. (CS)

Describes an experiment in which a subject spent more than 230 hours of practice in a laboratory and was able to increase his memory span from 7 to 79 digits. The results suggest that practice with an appropriate mnemonic system can increase memory performance. (Author/SA)

Some examples of high technology windmills. (MLF)

Describes an experiment conducted by two eighth grade home economics students in a gifted and talented program. A student-developed description of the experiment is provided. (LRA)

A method of estimating the solubilities of drugs in water is reported that is based on a principle applied in quantitative structure-activity relationships. This procedure involves correlation of partition coefficient values using the octanol/water system and aqueous solubility. (Author/MLW)

The study and construction of sundials is a useful teaching aid at several levels of instruction, since it involves understanding the shape, divisions, and major motions of the earth. (Author/RLV)

Reviews studies of regulation of nasal airway resistance (Rn). Describes methods of calculating Rn by measuring pressure-flow relationship. Data are presented on improved methods for measuring Rn and effects for expiratory and inspiratory Rn after topical application of phenylephrine nasal decongestant spray. (Author/SA)

Presents a reliable method for the sterilization of ciliates using common lab equipment and skills. A modified Glaser and Coria technique is used. (MA)

Wood pyrolysis is a process that burns wood without air, producing gas and oil that are then burned for heat. Now being tested at Maryville College, Tennessee, the process is expected to cut fuel costs, solve a waste disposal problem, and produce charcoal for sale. (Author/MLF)

A discussion of the aerodynamics of a boomerang as it relates to that of a golf ball. (BB)
