Properties of alkylating derivatives of estrogens

The influence of phenestrol and XTJI-51 (hexestrol alkylating derivatives) on uterine tissues and their ability to bind to estrogen receptors were studied. The both compounds studied exhibited estrogenic properties and imitated all effects of estradiol: they increased the uterine wet weight and the activity of thymidine kinase and glucose-6-phosphate dehydrogenase. Although their affinity for estrogen receptors was much weaker than the affinity of estradiol, their complexes with estrogen receptors were more stable than estrogen-receptor complexes.

Organizational Effects of Inequitable Rewards: Two Experiments in Status Inconsistency

Two organizational experiments were conducted to investigate the effects of overpayment and underpayment. Subjects were confronted with one of two organizational sources of inequitable payment. In one experiment their salary was inconsistent with their officially recognized level of competence; in another, their salary was inconsistent with their level of authority. Students were hired as proofreaders and worked in the actual offices of a publishing company. Status inconsistency was found to exert a significant effect on performance and to a lesser extent on conformity to organizational rules. Underpaid subjects behaved in accordance with equity theory by producing work of a lower level of quality; however, overpaid subjects did not behave consistently with the theory.

Selection and Evaluation of Thermal Interface Materials for Reduction of the Thermal Contact Resistance of Thermoelectric Generators

A variety of thermal interface materials (TIMs) were investigated to find a suitable TIM for improving the performance of thermoelectric power generators (TEGs) operating in the medium-temperature range (600–900 K). The thermal resistance at the thermal interface between which the TIM was inserted was evaluated. The TIMs were chosen on the basis of their thermal stability when used with TEGs operating at medium temperatures, their electrical insulating properties, their thermal conductivity, and their thickness. The results suggest that the boron nitride (BN)-based ceramic coating, Whity Paint, and the polyurethane-based sheet, TSU700-H, are suitable TIMs for the heat source and heat sink sides, respectively, of the TEG. Use of these effectively enhances TEG performance because they reduce the thermal contact resistance at the thermal interface.
