The Revised International Health Regulations and Their Relevance to Travel Medicine

JOURNAL OF TRAVEL MEDICINE, Issue 3 2007
MFPHM, MRCGP, Max Hardiman MBChB
The revised International Health Regulations 2005 (IHR 2005) will enter into force in June 2007. Here we give an overview of the IHR (2005) and their relevance to the travel medicine practitioner. The two specific applications of the IHR (2005) most likely to be encountered by travelers are the disinsection of aircraft to prevent importation of disease vectors and the yellow fever vaccination requirements imposed by certain countries. A model of the revised international certificate of vaccination or prophylaxis will be shown. The IHR (2005) has moved away from the definition of fixed maximum measures relating to specific diseases and in their place focus on the issuance of context-specific recommendations, made either on a temporary emergency basis or established for routine application in respect of ongoing risks of disease spread.

Multi-Output Capacity Measures and Their Relevance for Productivity

BULLETIN OF ECONOMIC RESEARCH, Issue 2 2000
Rolf FĂ
In this paper, measures of capacity are developed following those suggested in 1968 by Leif Johansen. By taking advantage of Shephard's duality, both primal and dual multi-output measures of capacity can be derived. Having generalized the capacity utilization measures, the authors show how these may be entered into measures of productivity. In particular, it is shown how the Malmquist direct and indirect productivity measures are related to various measures of capacity utilization. [source]

Trinuclear Rhodium Complexes and Their Relevance for Asymmetric Hydrogenation

CHEMISTRY - AN ASIAN JOURNAL, Issue 11 2008
Angelika Preetz
Abstract Various trinuclear rhodium complexes of the type [Rh3(PP)3(,3 -OH)x(,3 -OMe)2,x]BF4 (where PP=Me-DuPhos, dipamp, dppp, dppe; different ligands and , -bridging anions) are presented, which are formed upon addition of bases such as NEt3 to solvate complexes [Rh(PP)(solvent)2]BF4. They were extensively characterized by X-ray diffraction and NMR spectroscopy (103Rh, 31P, 13C, 1H). Their in,situ formation resulting from basic additives (NEt3) or basic prochiral olefins (without addition of another base) can cause deactivation of the asymmetric hydrogenation. This effect can be reversed by means of acidic additives. [source]
