Science and the American Century
The twentieth century was one of astonishing change in science, especially as pursued in the United States. Against a backdrop of dramatic political and economic shifts brought by world wars, intermittent depressions, sporadic and occasionally massive increases in funding, and expanding private patronage, this scientific work fundamentally reshaped everyday life. Science and the American Century offers some of the most significant contributions to the study of the history of science, technology, and medicine during the twentieth century, all drawn from the pages of the journal Isis. Fourteen essays from leading scholars are grouped into three sections, each presented in roughly chronological...
Controlled Release of Bioactive Materials
Controlled Release of Bioactive Materials is a collection papers that deal with the study of controlled release applications in drugs and other pharmacological products and processes. The text covers topics such as the theory and practice of controlled drug delivery from bioerodible polymers, biodegradable drug delivery systems from aliphatic polyesters, and the applications of osmotic drug delivery. Also covered are topics such as the application of polymers for the sustained release of macromolecules, controlled transdermal delivery, and the use of hydrogel devices for the controlled release of steroid hormones. The book is recommended for pharmacologists and doctors who would like to know more about advancements in the field of controlled release applications and its uses in healthcare, especially in pharmacology.

The african Honey Bee
This book is the first review of the scientific literature on the Africanized honey bee. The African subspecies Apis mellifera scutellata (formerly adansonii) was introduced into South America in 1956 with the intent of cross-breeding it with other subspecies of bees already present in Brazil to obtain a honey bee better adapted to tropical conditions. Shortly after its introduction, some of the African stock became established in the feral population around Sao Paulo, Brazil, and spread rapidly through Brazil. It has since migrated through most of the neotropics, displacing and/or hybridizing with the previously imported subspecies of honey bees. Africanized bees have been stereotype d as having high rates of swarming and absconding, rapid colony growth, and fierce defensivebehavior. As they have spread through the neotropics they have interacted with the human population, disrupting apiculture and urban activities when high levels of defensive behavior are expressed.
