abstract   background: to improve the debilitating features of parkinson disease (pd) different medical and surgical approaches are available. subthalamic nucleus deep brain stimulation (stn-dbs) was appeared to be a promising method during last two decades. this study aimed to evaluate early motor outcomes of this procedure in first trial of iranian patients .   methods: thirty-seven consecuti...

removal of thiosulfate (s2o32-, 200 mg/l) from simulated wastewater samples was investigated under varying co-pollutants and ph conditions employing the titanium dioxide (tio2) mediated photocatalysis. for thiosulfate only studies higher substrate removal was noted at lower ph with a specific trend of ph 4 > ph 7 > ph 10. furthermore, near complete thiosulfate removal was also achieved at ph 4....

objective(s): expression of her2 in gastric carcinoma has direct prognostic and therapeutic implications in patient management. the aim of this study is to determine whether a relationship exists between standardized uptake value (suv) and expression of her2 in advanced gastric carcinoma. methods: we analyzed the 18f-fdg pet/ct results of 109 patients that underwent gastrectomy for advanced gas...

in the present study, photocatalytic removal of p-nitrophenol has been carried out in the presence of zno by using a batch reactor with a uv-c lamp (15 w). the effects of applied zno concentration and uv light intensity have been studied. the increase of initial pollutant concentration decreases the removal rate, and the results indicate that the apparent reaction rate constant in the uv/zno pr...

statement of the problem some studies reveal that the oral cavity acts as a potential reservoir for h. pylori or a possible route of transmission. the aim of this study was to evaluate the association between advanced periodontal diseases and gastrointestinal problems and the effect of oral hygiene on this relationship. materials and methods this descriptive cross-sectional study was carried ou...

Abstract Drying process has been employed since ancient times to preserve agricultural products by reducing the moisture content. Solar dryer is one of most commonly used dryers due its availability, reliability, and environmentally friendly nature. It practical in rural areas solar can be fabricated with a simple design. Despite potential, designing long-term, feasible challenging without good...

Cogeneration and trigeneration systems have been broadly employed as part of the strategies oriented toward rational energy use. The assessment these must include simultaneous considerations costs, irreversibility, losses, their causes. This work presents a step-by-step thermoeconomic analysis microcogeneration unit, composed an internal combustion engine ammonia-water single-effect absorption ...

Abstract This article is based on the conceptual-thermodynamic design and exergoeconomic investigation of a new poly-generation system driven by biomass fuel (i.e. wood). In proposed energy system, Rankine power process, gasification desalination process multi-effect desalination, MED) water electrolyzer solid oxide cell, SOEC) are installed in hybrid form. Electric energy, fresh hydrogen gas u...
