The paper present the possibility of automatic control of the biological wastewater treatment station with applications in Romanian Chemical Companies. In this paper are developed a mathematical model for biological aeration basins and two automatic control systems (conventional control structure using threepositional controllers or PLC and advanced control structure using state estimators) for...
background: metronidazole, a 5-nitroimidazole derivative, is the main antitrichomonal agent of choice for treatment of t richomoniasis . since 1962, s ome cases of treatment failure with metronidazole have been reported and recently drug resistance is now on the rise in the world. this study was aimed to determine current susceptibility of iranian isolates of trichomonas vaginalis to me...
AIMS/INTRODUCTION Low aerobic capacity is a strong and independent predictor of all-cause mortality in patients with metabolic syndrome (MetS). Here, we investigated the effects of pioglitazone treatment on whole-body aerobic capacity and skeletal muscle energy metabolism in MetS patients. MATERIALS AND METHODS A total of 14 male patients with MetS received oral pioglitazone 15 mg/day for 4 m...
As a first step of treatment of landfill leachates (total COD – 1,430-3,810 mg/l, total nitrogen 90162 mg/l), a performance of laboratory UASB reactors has been investigated under mesophilic (30 C), sub-mesophilic (20 C) and psychrophilic (10 C) conditions. Under hydraulic retention times (HRT) of around 7 h, when the average organic loading rates (OLR) were around 5 g COD/l/day, the total COD ...
There is an ongoing need to treat leachates from landfills using approaches that avoid expensive installation and operating costs. Faced with such a problem, Powys County Council (Wales, UK) developed a treatment system based on practical experience. Leachate was re-circulated through aeration towers containing a biofilm supported on plastic media before being polished in reed/filter beds. Inve...
Multiple sclerosis leads to prominent hippocampal atrophy, which is linked to memory deficits. Indeed, 50% of multiple sclerosis patients suffer memory impairment, with negative consequences for quality of life. There are currently no effective memory treatments for multiple sclerosis either pharmacological or behavioral. Aerobic exercise improves memory and promotes hippocampal neurogenesis in...
