The occurrence of contaminants in wastewaters, and their behavior during wastewater treatment and production of drinking water are key issues to re-use water resources. The present research aims to remove caffeine from aqueous solutions via adsorption technique, using Multi-Wall Carbon Nanotubes (MWCNTs) as an adsorbent under different experimental conditions. The processing variables such as p...

a case with bilateral spontaneous pneumothorax was presented. etiology, mechanism, and treatment were discussed on the review of literature. spontaneous pneumothorax is a clinical entity resulting from a sudden non traumatic rupture of the lung. biach reported in 1880 that 78% of 916 patients with spontaneous pneumothorax had tuberculosis. kjergaard emphasized 1932 the primary importance of sub...

Turn-taking is usually considered to follow a simple set of rules, enacted through perhaps more complicated system signals. The most significant aspect the turn-taking process that, in cases, it proceeds very smooth fashion. Speakers signal each other that they wish either yield or take turn syntactic, pragmatic, and prosodic means. In this paper, I explore how develops two different sets Spani...

Background: Varicocele is related with poor semen quality and sperm chromatin integrity which possibility decreases the spontaneous pregnancy potential. Some of the varicocele individuals have normal semen parameters with failed pregnancy. It is also one of the most controversial issues in the field ofinfertility, especially regarding why, when and for whom varicocelectomy should be implemented...

In this article, the temperature behavior of output power of superluminescent light-emitting diode (SLED) by considering the effect of non-radiative recombination coefficient, non-radiative spontaneous emission coefficient and Auger recombination coefficients has been investigated. For this aim, GaN pyramidal quantum dots were used as the active region. The numerical method has been used to sol...

conclusions in cases of pontaneous pneumothorax, chest x ray and computerised tomographic scan have limitations. ct scan in combination with video assisted thoracoscopic surgery improves diagnostic accuracy and facilitates appropriate management of non-resolving spontaneous pneumothorax. objectives a 15 year old boy presented to the referring hospital with a right sided spontaneous pneumothorax...
