UNLABELLED A study was carried out to investigate the feasibility of achieving ultra low respirable suspended particulates (RSP) in commercial offices without major modification of existing ventilation systems by enhancing the particulates removal efficiency of existing central ventilation systems. Four types of filters which include pre-filters, cartridge filters, bag filters and high efficien...

Most of southern Africa's elephants inhabit environments where environmental temperatures exceed body temperature, but we do not know how elephants respond to such environments. We evaluated the relationships between apparent thermoregulatory behaviour and environmental, skin and core temperatures for tame savanna elephants (Loxodonta africana) that were free-ranging in the hot parts of the day...

Dear Editor, The modification of proliferating cell nuclear antigen (PCNA) by small ubiquitinlike modifier (SUMO) recruits Srs2 during S phase (Hoege et al., 2002; Pfander et al., 2005). The recruitment of Srs2 to replication fork through physical interaction between the C-terminus of Srs2 (residues 1038–1174) and SUMOylated PCNA regulates homologous recombination by disrupting the Rad51 nucleo...

OBJECTIVE To describe where smokers smoke outdoors, where non-smokers are exposed outdoors to secondhand smoke (SHS), and attitudes towards smoke-free outdoor areas after the implementation of national smoke-free legislation. DESIGN This cross-sectional study was conducted between June 2011 and March 2012 (n=1307 participants). SETTING Barcelona, Spain. PARTICIPANTS Representative, random...

BACKGROUND Climate change may lead to more severe and extreme heat waves in the future, but its potential impact on sudden infant death-a leading cause of infant mortality-is unclear. OBJECTIVES We sought to determine whether risk of sudden infant death syndrome (SIDS) is elevated during hot weather. METHODS We undertook a case-crossover analysis of all sudden infant deaths during warm peri...

A Russian spacecraft will be launched to Mars in November 1996. Two German multiple line scanners on board, HRSC (High Resolution Stereo Camera) and WAOSS (Wide Angle Optoelectronic Stereo Scanner), will obtain highand low resolution multiphase color stereo images for geoscientific, photogrammetric, and cartographic studies of our neighbor planet and for studies of its atmosphere. The cameras a...

The rise of the periphrastic future (PF) at the expense of the inflected future (IF) is an established historical trend in Québécois French over at least the past 150 years. Previous research has also found higher rates of PF among younger speakers, many displaying categorical use in affirmative contexts. Because an apparent time interpretation of the synchronic data fits the historical record,...

BACKGROUND On January 1, 2008, the French government implemented a national ban on indoor smoking in hospitality venues. Survey results indicate the indoor ban has been successful at dramatically reducing indoor smoking; however, there are reports of an increased number of outdoor hospitality spaces (patios) where smoking can take place. This study sought to understand if the indoor ban simply ...
