Brain Barrier Systems, Volume 29In recent years, many important developments have occurred in many research disciplines that are directly related to brain permeability. In morphological fields, the fine resolution provided by electron microscopy has resulted in new concepts of membrane structure. Electron microscopy, combined with autoradiography, have contributed significant information concerning dynamic events occurring in and around such membranes. Permeability measurements with drugs have led to new theories of the physical and chemical requirements which determine the penetration of drugs
An important U.S. ally in the Middle East, Saudi Arabia is a mysterious land to most Americans, who may know it only as the place where Islam originated and Islamic fundamentalism is a powerful force. In recent years, the relationship between the governments of the U.S. and Saudi Arabia has come under increasing scrutiny, and among the general public in the U.S. there is a need and desire for a greater understanding of Saudi Arabia.
Much has been written about communicating within organizations but relatively little on the critical skill of communicating upward. Green and Knippen, experts in employee motivation and performance, show how essential it is to the success of an organization, public or private, for employees to get their ideas up the ladder and into the hands of the decision-makers. Their book outlines more than 40 specific upward communication needs and offers a structure that will ensure that the movement of ideas upward actually takes place.
The Great Barrier Reef: Biology, Environment and Management
The Great Barrier Reef Marine Park is 344 400 square kilometres in size and is home to one of the most diverse ecosystems in the world. This comprehensive guide describes the organisms and ecosystems of the Great Barrier Reef, as well as the biological, chemical and physical processes that influence them. Contemporary pressing issues such as climate change, coral bleaching, coral disease and the challenges of coral reef fisheries are also discussed.
