In this paper we present a comparative assessment of drinking-water standards from almost all South American countries, using the USA and the Canadian standards and the World Health Organization (WHO) Guidelines as references. Similarities and discrepancies between standards/guidelines were identified through descriptive analyses and, in the case of chemical standards, clustering techniques. In...

background: for planning in health,preventing and representing valuable dentistry services, we need to identify and evaluate the information on the status of individuals' dental hygiene and health. in this examination, evaluating dental health which is one of hygienic main and key problems has been conducted according to world's standards in correction center of tehran province in 200...

We drew on institutional and learning theories to develop a research model assessing how organizations influence standards deployment and integration by creating institutional pressures and learning opportunities. We also examined how standards deployment and integration differentially influenced operational and strategic benefits. Survey data was collected from organizations in China who have ...

The American Diabetes Association (ADA) "Standards of Medical Care in Diabetes" includes ADA's current clinical practice recommendations and is intended to provide the components of diabetes care, general treatment goals and guidelines, and tools to evaluate quality of care. Members of the ADA Professional Practice Committee, a multidisciplinary expert committee, are responsible for updating th...

OBJECTIVE Pharmacological and lifestyle interventions are recommended for the reduction of stroke risk in people who have had a transient ischaemic attack (TIA). This study aimed to investigate the quality of secondary stroke prevention in primary care following diagnosis of TIA in a specialist clinic. METHODS Quality standards were identified from the Royal College of Physicians (RCP) nation...

The status of the heavy quark expansion for inclusive B decays is briefly reviewed from the perspective of confronting theory with data and of extracting the heavy quark parameters. A good agreement between properly applied theory and new precision data is observed. Some recent applications to the exclusive heavy flavor transitions are addressed. I recall the ‘ 1 2 > 3 2 ’ paradox for the trans...

We argue that there is strong experimental evidence in the data of band c-decays that the pattern of power suppressed corrections predicted by the short distance expansion, the heavy quark effective theory and the assumption of local duality is not correct for the non-leptonic inclusive widths. The data indicate instead the presence of 1/m corrections that should be absent in the above theoreti...

We provide a brief overview of some current experimental and theoretical issues of heavy quark production.
