Detection of diatoms in blood by a combination of membrane filtering and chemical digestion

An improved method for detecting diatom in blood is reported. Blood of cadavers was obtained by cardiac puncture at inquest or from the left atrium directly at autopsy. The blood was hemolyzed by sodium dodecyl sulfate (SDS) and filtered through membrane filter (47 mm in diameter and 5 microns in pore size). When the blood was putrefied, two or three pieces of membranes filters were needed because of choking membrane pore. The membrane filters were digested with fuming nitric acid and diluted with distilled water. The diluted solution was filtered through membrane filter (25 mm in diameter) again. After drying the membrane filter was immersed in oil. Diatoms on the membrane filter were clearly observed microscopically.     

South Asian nuclear arms competition: An American perspective∗

The analysis of nuclear arms competition in South Asia forms part of a much larger study of American relations with the region after the Cold War carried out under the auspices of The Asia Society. The nuclear policies of both India and Pakistan enjoy strong domestic political support. While a case can be made that a rudimentary state of nuclear deterrence exists between New Delhi and Islamabad, this may be undermined by deployment on both sides of ballistic missiles.     

The intellectual legacy of J.E. Hodgetts

Abstract: J.E. (Ted) Hodgetts was influenced by both the political economy approach that he learned at the University of Toronto and by the comprehensive historical method developed by Leonard White, under whom he studied at Chicago. His first great project, Pioneer Public Service, convinced him that responsible government was impossible without responsible public administration. The authors examine how his response to management theories and practices evolved following his participation in the Glassco, Lambert and Gomery commissions. Hodgetts consistently refused the complete separation of politics and administration, and he promoted the use of management techniques to strengthen parliamentary supervision of the public service. The two key components of his legacy are thus a commitment to the democratic values of representative government and the comprehensive study of the internal dynamics of public administration in interaction with the relevant environmental factors.
