Experimental techniques are now available which can probe the intricacies of carbohydrate structures, equilibria and dynamics. The development of theoretical tools has not kept pace with this progress; the reliance on hard sphere models and orientational averaging is unlikely to reveal the true nature of the phenomena involved. Computer simulation of PHCs in solution may, in the hands of expert...

BACKGROUND Sizwe Tropical Diseases Hospital is the only specialized Hospital for the management of multidrug-resistant (MDR)-TB and extensively drug-resistant (XDR)-TB cases in Gauteng Province. In South Africa, there is a mismatch between numbers of individuals with a laboratory diagnosis of drug-resistant tuberculosis (TB) and those being referred for the initiation of specialist treatment. W...

AIMS (1) To examine whether prevalence of burnout is higher among community psychiatric nurses working under recently introduced job specific work systems than among public health nurses (PHNs) engaged in other public health services. (2) To identify work environment factors potentially contributing to burnout. METHODS Two groups were examined. The psychiatric group comprised 525 PHNs primari...

Light-emitting diodes (LEDs), including organic LEDs and polymer LEDs, have been studied intensively for use in displays and interior lighting due to their promising advantages of high effi ciency, high contrast ratio, long lifetime and low power consumption. [ 1 , 2 ] However, in a conventionally structured LED, less than 20% of the generated light is emitted as useful radiation. [ 3 , 4 ] Not...

There is an increasing focus on research related to the removal of emerging organic contaminants (EOCs) from wastewater by using constructed wetlands (CWs). However, lacking translating available scientific evidence into decision support tools. In this paper, a novel tree framework developed and demonstrated. The proposed consists five steps: (1) generate list EOCs analysis wastewater; (2) sele...

Response issued draft vapor intrusion guidance (EPA, 2002), which specifically states that it is not recommended for Subtitle I underground storage tank (UST) sites. EPA's Office of Underground Storage Tanks (OUST) is thus currently developing guidance to address petroleum vapor intrusion (PVI) at UST sites. OUST has consulted on several occasions with experts in the field of vapor intrusion an...

Introduction The National Rural Health Mission (NRHM) has initiated community-based institutions at various levels of the health system e.g. Arogya Raksha Samithi (ARS) and Planning and Monitoring Committee (PMC) at Primary Health Center (PHC) level while the Village Health and Sanitation Committee (VHSC) at the revenue village level. These institutions are intended to create awareness about he...

Response issued draft vapor intrusion guidance (EPA, 2002), which specifically states that it is not recommended for Subtitle I underground storage tank (UST) sites. EPA's Office of Underground Storage Tanks (OUST) is thus currently developing guidance to address petroleum vapor intrusion (PVI) at UST sites. In September 2009, OUST assembled experts in the field of vapor intrusion and petroleum...

BACKGROUND/AIM Early diagnosis of chronic illnesses and cancers mainly occurs at primary health care centers (PHCs) by primary health care physicians (PHPs). The incidence of colorectal cancer (CRC) in the Kingdom of Saudi Arabia (KSA) is rising and this has been attributed to many factors. The increasing incidence of CRC is compounded by nonadherence to screening recommendations. Therefore, ev...

Background: Variations in the risk of malaria across locations exist but are poorly understood though identifying hotspots transmission will create opportunities for targeted interventions. Point prevalence Rivers State was studied using Primary Healthcare Centres (PHCs) as survey points.
 Methods: The PHCs were geo-referenced a handheld Global Positioning System (GPS) and 74 selected 21 l...
