The dry reforming of methane (DRM) using biogas and a Ni-based catalyst for syngas production was studied experimentally in this study under the presence H2S. Using nonpoisoned DRM performance as comparison basis, it found that deactivation by sulfur chemisorption onto surface depends on both reaction temperature time. With low temperatures, complete coverage resulted could not be regenerated. ...

BACKGROUND Renal failure is an important adverse effect of drug poisoning. Determining the prevalence and etiology of this serious side effect could help us find appropriate strategies for the prevention of renal failure in most affected patients. OBJECTIVES The present study is aimed to identify drugs that induce renal failure and also to find the prevalence of renal failure in patients refe...

Incorporation of C-depleted (old) dissolved organic carbon (DOC) on/into particulate organic carbon (POC) has been suggested as a possible mechanism to explain the low DC-POC values observed in the deep ocean [Druffel, E.R.M., Williams, P.M., 1990. Identification of a deep marine source of particulate organic carbon using bomb C. Nature, 347, 172–174.]. A shipboard incubation experiment was per...

Bachground: Toxic plants are an important reason for poisoning. The responsible plants are variable in different geographic spots. Some areas such as Lorestan province have more variety in herbal plants because of geographic condition. Because of high poisoning incidence with toxic plants and mushroom, we assessed the incidence of poisoning with mushroom and toxic plants (Tattore and Ricinus ...
