English | ISBN: 1621007669 | 2012 | 332 pages | PDF | 7 MB
The blood-brain barrier (BBB) is a highly regulated system that maintains brain allostasis. BBB achieves its main function by transporting blood to brain glucose, amino acids and other molecules needed for proper neural physiology, while extruding from the brain molecules derived from neural and glial metabolism that may have neurotoxic properties. In this book, the authors present topical research in the study of blood-brain barriers including their local and temporal regulation during normal and altered physiological states; the therapeutic opportunities of efflux-transporters at the blood-brain barrier; novel strategies to restore blood-brain barrier integrity after brain injury; evaluation of the blood-cerebrospinal fluid barrier in neurological diseases and blood-brain barrier in hepatic encephalopathy

For fans of The Boys in the Boat, and marking the 100th anniversary of the Paris Olympics, the never-before-told story of three athletes who defied the odds to usher in a golden age of sports
Even today, it’s considered one of the most thrilling races in Olympic history. The hundred-meter sprint final at the 1924 Paris Games, featuring three of the world’s fastest swimmers-American legends Duke Kahanamoku and Johnny Weissmuller, and Japanese upstart Katsuo Takaishi-had the cultural impact of other milestone moments in Olympic history: Jesse Owens’s podiums in Berlin and John Carlos’s raised, black-gloved fist in Mexico City. Never before had an Olympic swimming final prominently featured athletes of different races, and never had it been broadcast live. Across the globe, fans held their breath.
In less than a minute, an Olympic record would be shattered, and the three men would be scrutinized like few athletes before them. For the millions worldwide for whom swimming was a complete unknown, the trio did something few could imagine: moving faster through water than many could on land. As sportsmen, they were godlike heroes, embodying the hopes of those who called them their own, in the US and abroad. They personified strength and speed, and the glamour and innovation of the Roaring Twenties. But they also represented fraught assumptions about race and human performance. It was not only "East vs. West"-as newspapers in the 1920s described the competition with Japan-it was also brown versus white. Rich versus poor. New versus old. The race was about far more than swimming.

Free Download Liquid Separations with Membranes: An introduction to barrier interference By Karl Wilhelm Böddeker (auth.)
2008 | 146 Pages | ISBN: 354047451X | PDF | 2 MB
On the level of a textbook a self-consistent approach to liquid separations with membranes is presented, contrasting equilibrium separations with the rate-controlling effects of barrier interference on mass transfer. As a corollary objective, an effort is made to observe context, factual and historical, when introducing concepts and applications of membrane separation science. Ordering principle is the formal structure of mass transfer across barriers, being construed of a driving force (allocated to the condition of the mixtures to be separated) and a barrier permeability (holding the keys to membrane selectivity). The membranes, by this approach, appear by way of the mass transport demands which they are to meet, or else by way of the separation effects which they inspire. Learning by principles and context – exploiting barrier interference is the challenge of membrane separation science and technology. This book is about the principles behind.

Free Download The Barrier Zones in the Ocean By Dr. Emelyan M. Emelyanov (auth.)
2005 | 632 Pages | ISBN: 3540253912 | PDF | 19 MB
Geochemical barrier zones play an important role in determining various physical systems and characteristics of the oceans, e.g. hydrodynamics, salinity, temperature and light. In this book, each of the 40 barrier zones covered are illustrated and defined by physical-chemical parameters. Among the topics discussed are the processes of inflow, transformation and precipitation of the sedimentary layer of the open oceans and more restricted areas such as the Baltic, Black and Mediterranean Seas. This well-illustrated book may serve as the basis for courses such as "Marine Geochemistry" or "Ocean Usage" and can be useful to researchers in the fields of geology, geography, marine chemistry, geoecology and hydrochemistry.
