Privileged and Confidential: The Secret History of the President's Intelligence Advisory Board
Above the politics and ideological battles of Washington, D.C., is a committee that meets behind locked doors and leaves its paper trail in classified files. The President's Intelligence Advisory Board (PIAB) is one of the most secretive and potentially influential segments of the U.S. intelligence community. Established in 1956, the PIAB advises the president about intelligence collection, analysis, and estimates, and about the legality of foreign intelligence activities. Privileged and Confidential: The Secret History of the President's Intelligence Advisory Board is the first and only study of the PIAB. Foreign policy veterans Kenneth Michael Absher, Michael C. Desch, and Roman Popadiuk trace the board's history from Eisenhower through Obama and evaluate its effectiveness under each president. Created to be an independent panel of nonpartisan experts, the PIAB has become increasingly susceptible to politics in recent years and has lost some of its influence. Absher, Desch, and Popadiuk, however, clearly demonstrate the board's potential to offer a unique and valuable perspective on intelligence issues. Privileged and Confidential not only illuminates a little-known element of U.S. intelligence operations but also offers suggestions for enhancing a critical executive function.
Improving Hollow Fiber Dialyzer Efficiency with a Recirculating Dialysate System II: Comparison Against Two-Chamber Dialysis Systems
The theoretical basis of the nonregenerated recirculating dialysate system (RDS) was derived in Part I of this work [M. Prado, L. M. Roa, A. Palma, and J. A. Milán, Ann. Biomed. Eng. (2005)]. This system pursues the maximization of the clearance of hollow fiber dialyzers whose performance is controlled by diffusion, as occurred in standard hemodialysis. In this second part we perform a comparison by digital simulation of the RDS against three well-known two-chamber dialysis systems. As a major outcome, the efficiency of the RDS increased by a factor of five–eight with respect to the efficiency of a single dialyzer operating with a number of transfer units equal to 0.1, that is when the diffusive mass-transfer of the dialyzer is exhausted. Present low-flux dialyzers do not take advantage of the full potential of this technique, but the functional domain where high-flux and high-area dialyzers operate could be more suitable to exploit this technique. We conclude that RDS can be a competitive efficient technique for optimizing the dialysis efficiency.
