The Mary Lasker Conferences, sponsored by the American Cancer Society, have the goal of sharing information in a critical cancer research field. The Lasker Conference held in December 1989 focused on the subject of Growth Factors in Hormonerelated Tumors and was initiated because of rapid progress in the understanding of growth factors, growth factor receptors, hormone action, and oncogenes. Th...

Since flooding in the wake of Hurricane Katrina devastated the city of New Orleans, a number of elections took place in the city under unusual circumstances, with voting centers being provided outside the city limits. The state elections in the fall of 2007 were the first contests to take place largely under “normal” voting arrangements, with displaced voters casting ballots either by voting ea...

This paper describes an approach to crystal engineering based on designing and analyzing hierarchical levels of crystal l ine architecture. The system under study consists of 1:1 co-crystals of melamines and barbituric acids that selfassemble into crystallographically infinite hydrogen-bonded tapes. The formation of structural elements can be rat ional ized and control led using famil iar molec...

Two experiments were conducted to evaluate the effects of drinking water temperature (Tw) on laying hens subjected to warm cyclic air temperature (Ta) conditions. Each experiment consisted of a 1-wk acclimation under thermoneutrality (TN) (Ta = Tw = 21 C), a 4-wk heat exposure or treatment period, and a 2-wk recovery under TN. Each experiment involved 24 individually caged hens at the initial a...
