Abstract This paper analyses the role that companion policies have had in reduction of emissions regulated by EU Emissions Trading System (EU ETS) and related policy interactions, with a view to identifying relevant insights for China's forthcoming (ETS). The investigation rests on: (a) observation EU's ETSs mixes; (b) economic theory concerning ETS design; (c) empirical ex-post evidence from E...
Theoretical studies of the thermal state heat storage elements with air channels various shapes in modes charging and output electric (ETS) are carried out. The mathematical model exchange processes adapted to operating ETS is presented. change average transfer coefficient conditions natural forced convection ETS, flux density mode from a tubular heating element (TEH) for slit round shape shown...

BACKGROUND Environmental tobacco smoke (ETS) has adverse effects on the health of asthmatics, however the harmful consequences of ETS in relation to asthma severity are unknown. METHODS In a multicenter study of severe asthma, we assessed the impact of ETS exposure on morbidity, health care utilization and lung functions; and activity of systemic superoxide dismutase (SOD), a potential oxidat...
CCN2 is encoded by an immediate-early gene induced in mesenchymal cells during the formation of blood vessels, bone and connective tissue. It plays key roles in cell adhesion and migration, as well as matrix remodeling. CCN2 is overexpressed in fibrosis, arthritis and cancer; thus, an understanding of how to control CCN2 expression is likely to have importance in developing therapies to combat ...
OBJECTIVE Endotracheal tube suctioning (ETS) is a painful and invasive procedure. Studies have shown that the performance of nurses in this procedure is weak, so we conducted a study to evaluate the effect of ETS education for nurses on neonates' pain in neonatal intensive care units (NICUs). METHODS In a quasi-experimental study, performance of 25 nurses working in NICU was assessed before a...
BACKGROUND A transcription factor, ets-1, regulates the transcription of metalloproteinase genes, the activity of which is necessary for matrix degradation and the migration of endothelial cells. However, no study has demonstrated that ets-1 itself has an angiogenic action in vivo. Thus, we examined (1) the effects of overexpression of the ets-1 gene on angiogenesis in a rat hindlimb ischemia m...
BACKGROUND Environmental tobacco smoke (ETS) contains tobacco carcinogens. Hepatic cytochrome P450 (CYP) 1A2 and N-acetyltransferase (NAT2) are important isoenzymes in activation and detoxification, respectively, of tobacco carcinogens. Data on ETS and bladder cancer risk are sparse. METHODS We examined the effects of ETS alone and combined with NAT2/CYP1A2 on bladder cancer risk among lifelo...
The evidence that ETS increases risk of death from heart disease is similar to that which existed in 1986 when the US Surgeon General concluded that ETS caused lung cancer in healthy nonsmokers. There are 10 epidemiological studies, conducted in a variety of locations, that reflect about a 30% increase in risk of death from ischemic heart disease or myocardial infarction among nonsmokers living...
This study tested the hypotheses that (1) increased platelet aggregation, as measured by 2,3-dinor-thromboxane B(2) (Tx-M) and 2,3-dinor-6-keto-prostaglandin F(1alpha) (PGI-M), and (2) increased oxidative stress, as measured by 8-Hydroxy-2'-deoxyguanosine (8-OHdG), would occur in ETS-exposed nonsmokers as compared with non-ETS-exposed nonsmokers. The concentrations of the stable urinary metabol...
