INTRODUCTION Smoke-free homes can help protect children from tobacco smoke exposure (TSE). The objective of this study was to conduct a meta-analysis to quantify effects of interventions on changes in tobacco smoke pollution in the home, as measured by air nicotine and particulate matter (PM). METHODS We searched MEDLINE, PubMed, Web of Science, PsycINFO, and Embase. We included controlled tr...

People with vertigo have the illusion that the environment is moving about them, or that they are moving with respect to the environment.(DTB 2009) The condition usually originates in the peripheral nervous system, for example, due to a disorder of the inner ear such as Ménière's disease, benign paroxysmal positional vertigo (BPPV), or labyrinthitis and vestibular neuritis. It can also be due t...

Using a combination of aspirin, anti-tuberculosis drugs and steroids may help to reduce the number of strokes and deaths in patients with tuberculous meningitis.

Complementation and determinization are two fundamental notions in automata theory. The close relationship between the two has been well observed in the literature. In the case of nondeterministic finite automata on finite words (NFA), complementation and determinization have the same state complexity, namely Θ(2n) where n is the state size. The same similarity between determinization and compl...

Carbon dioxide (CO2 ) sensors that provide a visual indication were installed in classrooms during normal school operation. During 2-week periods, teachers and students were instructed to open the windows in response to the visual CO2 feedback in 1 week and open them, as they would normally do, without visual feedback, in the other week. In the heating season, two pairs of classrooms were monit...

In low-heating-energy buildings heat pumps have become an attractive heating system due to a notable reduction of the space heating requirements and the introduction of low temperature heating systems. Comfort cooling becomes also more important, especially in lightweight buildings with large south-oriented windows, which partially tend to overheat in summer. A heat pump has the unique feature ...
