This paper presents the initial results of a project initiated by the American Society of Heating, Refrigerating and AirConditioning Engineers (ASHRAE) and the National Research Council of Canada to investigate smoke movement resulting from a sprinklered fire in a communicating space into an adjacent large open area such as an atrium or retail mall. Recent research on the interaction of sprinkl...

Abstract Smoke-derived seed germination is an important trait for plants to colonize postfire habitats. The well-characterized smoke-derived chemicals of karrikins germinate seeds species not known occur after fires in nature. Hence, the ecologically relevant cues smoke remain be explored native plants. With fire-chaser, Nicotiana attenuata , we revisit a bioassay-driven fractionation liquid id...

Cigarette smoke is known to cause acute increases in airway resistance, but the mechanisms behind this effect are unknown. Lung explants were utilized to examine the constrictive effects of acute cigarette smoke exposure on bronchioles from rats in vitro that had or had not been previously exposed to cigarette smoke in vivo. It was found that smoke induced a small but consistent degree of contr...

The recent report on secondhand smoke from the U.S. Surgeon General has already been the impetus for several new smoking bans and may be the starting point for a national movement, according to smoke-free advocates. " The scientifi c evidence is now indisputable: Secondhand smoke is not a mere annoyance. It is a serious health hazard that can lead to disease and premature death in children and ...

DESIGN Cross sectional analysis of data collected in the September and November 1995 Omnibus Survey, conducted by the Office of Population Censuses and Surveys in the UK. SUBJECTS A random sample of British households. Interviews ...

BACKGROUND Reductions in admissions for myocardial infarction (MI) have been reported in locales where smoke-free workplace laws have been implemented, but no study has assessed sudden cardiac death in that setting. In 2002, a smoke-free restaurant ordinance was implemented in Olmsted County, Minnesota, and in 2007, all workplaces, including bars, became smoke free. METHODS To evaluate the po...

Cigarette smoke, a mixture of over 7,000 chemicals, can affect development of the nervous system prenatally, which can produce cognitive problems in children after birth. The purposes of this study were to determine if chemicals in mainstream (MS) and side-stream (SS) cigarette smoke adversely affect proliferation of neural stem cells, which could explain the effects observed in humans, and to ...

ABSTRACT The growth of good and quality seeds requires a lot fertilization, considering that oil palm grow quickly. Generally, the fertilizers used are compound inorganic single fertilizers. Continuous use without being balanced by organic can reduce soil quality. Therefore, alternative needed to Liquid smoke from midrib-leaf waste be developed into fertilizer, so studies needed. This study aim...

This study aims to identify support for smoke-free policies among university students. A cross-sectional was conducted 406 students from three main campuses of a in 2018. standardized questionnaire administered on sociodemographic characteristics, knowledge, and habits towards tobacco use influence. There significant association between knowledge secondhand smoke (SHS) the types tobacco-free po...

During wildfires large amounts of volatile phenols (VP’s) are released into the air from wood burning. These compounds absorb through berry skin, where they quickly glycosylated. Studies have shown that both free and bound contribute to smoke taint perception. For grape exposure risk assessment, natural amount VP’s in grapes (baseline) as well rejection threshold levels these different wine mat...
