Solar concentrators offer good promise for reducing the cost of solar power. Planar waveguides equipped with a microlens slab have already been proposed as an excellent approach to produce medium to high concentration levels. Instead, we suggest the use of a cylindrical microlens array to get useful concentration without tracking during the day. To use only a seasonal tracking system and get th...

AIMS Country differences in management practices are evident, and the publication of management guidelines by the European Society of Cardiology (ESC) and other learned societies has tried to recommend a uniform evidence-based approach to management. Despite the availability of guidelines and efforts to improve implementation, differences in guideline adherence are evident, and differences betw...

DESIGN A cross-sectional study. SETTING Primary healthcare unit in Oslo, Norway, offering family immigrants, asylum seekers, United Nations (UN) refugees or individuals granted as...

THE NORTHERN TERRITORY Situated in the centre of Australia, the Northern Territory is the third largest state in Australia and is roughly the size of France, Spain and Italy combined (figures 1 and 2). It has a unique environment that ranges from arid desert down south to tropical regions on the coast in the north. The Northern Territory is often considered the quintessential Australian outback...

The study site was not located as stated (Pg 14142, Ln 10) in the west but in the east of Sacramento adjacent to the Sacramento Valley. The predominant wind direction at the study site is from the west and the source area does not include areas with extensive cattle but rather crop production. In fact, the San Joaquin Valley (SJV) where dairy production takes place to a considerable extend is l...

For geographic applications, it is of great interest to study the geometric properties of the sphere. Spatial models that directly deal with geographic coordinates are able to contemplate such aspects that would be otherwise disregarded by flat 2D models. For example, on the Earth’s surface, a point which is to the East of another point could be reached travelling to West as well. Being situate...

Background. Screening of children who are household contacts of tuberculosis (TB) cases is universally recommended but rarely implemented in TB endemic setting. This paper aims to summarise published data of the prevalence of TB infection and disease among child contacts in South East Asia. Methods. Search strategies were developed to identify all published studies from South East Asia of house...

This manuscript is the result of ethnobotany and ethnopharmacology survey on the Hezar Mountain in SE of Iran. Traditional botanical medicine is the primary mode of healthcare for most of the population of this region. The plants were collected in and around Hezar mountain from 2008-2010. The authors have conducted an interview of total 75 informants; The traditional uses of 92 species belongin...

BACKGROUND AND AIM To identify the geographic distribution of hepatitis C virus (HCV) genotypes and HCV RNA viral load in a large number of HCV-infected carriers in Mexico. METHODS Patients with chronic hepatitis C (n = 8,802) were studied to identify HCV genotype using an immune line probe assay in samples shown previously to be positive for viral RNA by an RT-PCR test. Baseline HCV RNA was ...
