A commercial carbon fabric intended for aerospace applications was characterized as an activated carbon, since it had sufficient surface area and pore volume to warrant such consideration. Evaluation was achieved by means of nitrogen sorption (BET method), mercury porosimetry, sorption of CCl4 vapor, density in water and helium, and sorption of Meth ylene Blue from aqueous solution. The carbon textile appeared to be most suitable for gas and vapor sorption, but a signifi cant capacity for liquid phase sorption was also demonstrated.

This study investigated the ability of a learning module to influence counselors' decisions about confidential information. The module was a self-paced, programmed text written in prose style consisting of behavioral objectives, readings, paper-and-pencil tasks, field activities, and feedback. The study, involving 82 students, used a Solomon-type design of five groups in controlling for the effect of pretesting when the module was used under two conditions: independent study and study in dyads. Analysis of change scores using nonparametric statistics indicated that, when compared with a control group, module users studying alone and in pairs showed significant changes in decisions they made about confidential information.

Lignin is a polyphenolic compound found in plant tissues, especially wood and bark. The lignin content determines the quality of wood biochar in agroecological uses, and is used in the production of synthetic resins and adhesives. Despite its importance in plant physiology and its agricultural and industrial utility, there exists a wide gap of knowledge of lignin contents of tropical hardwood trees of South Asia, except for a few species. We present here the first estimation of lignin content in wood and bark of 48 species from tropical deciduous forests of India. We show that some species are characterized by greater wood lignin (WL) compared with bark lignin (BL) content, contrary to the generalization held for hardwood trees, and suggest a plausible correspondence between the WL to BL ratio and timber quality.
