Highly efficient and selective electrochemical reduction of carbon dioxide represents one of the biggest scientific challenges in artificial photosynthesis, where carbon dioxide and water are converted into chemical fuels from solar energy. However, our fundamental understanding of the reaction is still limited and we do not have the capability to design an outstanding catalyst with great activ...

rhinophyma is a severe late complication of rosacea, which is characterized by progressive hyperplasia of sebaceous glands and connective tissue involving the lower two-thirds of the nose. it can be an emotionally devastating disorder, and serve as a medium for occult cancers and other health problems. many surgical treatments have been advocated, as well as dermabrasion and laser therapy. in l...

to study the effects of carbon dioxide enrichment on morphological, nutrient absorption and yield of wheat (triticum aestivum l. cv. pishtaz) under weed competitive pressure of wild oat (avena ludovicianal.), an experiment was conducted as a split plot based on a randomized completely block design during the 2013-2014 growing season at the research field of tarbiat modares university, iran. car...

At present there is experimental and clinical evidence to support the view that alteration in alveolar oxygen tension has a direct effect on pulmonary circulation. Animal experimentation (1-4) and hemodynamic studies in human subjects (5-8) indicate that pulmonary vascular resistance increases and blood flow is thereby reduced in hypoxic areas of the lung. This is apparently a mechanism by whic...

This paper applies Pedroni's panel cointegration approach to explore the causal relationship between trade openness, carbon dioxide emissions, energy consumption and economic growth for the panel of newly industrialized economies (i.e. Brazil, India, China and South Africa) over 1 Corresponding author the period of 1970–2013. Our panel cointegration estimation results found majority of the vari...

Monoacylglycerol lipase (MGL) is a multifunctional serine hydrolase, which terminates anti-nociceptive endocannabinoid signaling and promotes pro-nociceptive prostaglandin signaling. Accordingly, both acute nociception and its sensitization in chronic pain models are prevented by systemic or focal spinal inhibition of MGL activity. Despite its analgesic potential, the neurobiological substrates...

1.1 Carbon dioxide sequestration in sub-seabed geological formations is a process consisting of separation of carbon dioxide from industrial and energy-related sources, transport to an offshore geological formation, and long-term isolation from the atmosphere. This process is one option in a portfolio of mitigation actions for stabilization of atmospheric greenhouse gas concentrations with the ...

RECENTLY a great deal of attention has been focused on the problem of carbon dioxide accumulation during anaesthesia (Stead et ah, 1953; Harbord, and Lucas, 1953). A number of articles have appeared describing investigations on the actual figures for " alveolar air " or arterial carbon dioxide tensions found during anaesthesia. Ringrose et al. (1950) developed a carbon dioxide indicator showing...

Forests have a key role as carbon sinks, which could potentially mitigate the continuing increase in atmospheric carbon dioxide concentration and associated climate change. We show that carbon dioxide enrichment, although causing short-term growth stimulation in a range of European tree species, also leads to an increase in soil microbial respiration and a marked decline in sequestration of roo...
