objective: bone marrow transplantation is considered one of the main procedures used in the treatment of both malignant and non-malignant diseases. psychological factors after bone marrow transplantation have an important role in the survival of the patients undergoing this procedure. method: in the present study, some parameters including depression, anxiety and cognition were assessed during ...

CO2 is among the most stable molecules, requiring high amounts of energy to be activated. Photosynthesis allows the conversion of CO2 and H2O, the major products of combustion, into useful organic compounds and represents one of the most efficient ways for CO2 capture, besides its absorption in oceanic water. This is a natural but complex process leading to a regenerated fuel by photo-irradiati...

We studied flow rate, electrolytes effects, titanium dioxide separation and reuse and sunlight application on photocatalysis in a tubular photoreactor integrated with the titanium dioxide separation/reuse. The circulative flow treatment was preferred over the single pass treatment. Phenol and TOC removals in tap and deionized waters were a maximum at the circulative flow rate of 600 ml min and ...

Introduction The use of reformulated and alternative fuels has been increasingly tested during recent years in order to improve air quality by lowering the ozone formation of air pollution in urban areas. However, most of these investigations were carried out rather indirectly using e.g. artificial exhaust gas mixtures. The investigations, which are presented here were focused on gasoline and d...

information available on the web can be divided in two main categories. the first category is those information distributed among different websites and servers. the second category is the information gathered in central information databases (infobases) which contain a huge amount of information and are available and searchable through the website representing the infobase. infobase owners sel...

In this study, degradation of p-chlorophenol (p-CP) was evaluated using persulfate (PS) activated zerovalent iron (ZVI) based ultraviolet (UV) in a bench scale photoreactor. The effect of operational parameters such as solution pH (3, 7, and 11), reaction time (0-60 minutes), ZVI dosage (0.15, 1.25, 0.5, 1, and 1.5 mM), PS concentration (0.5, 1.5, 2, 2.5, 3, and 4 mM), and initial p-CP concentr...

Methane (CH4) is the second largest contributor to global warming among all greenhouses gases. A solar chimney power plant integrated with a photocatalytic reactor (SCPP-PCR) promising large-scale method for removing CH4 from atmosphere. This study used computational fluid dynamics (CFD) investigate performance and factors influencing oxidation of methane by SCPP-PCR system. The geometry SCPP s...
