in this research, an experimental study to evaluate nutrient removal from synthetic wastewater by a lab-scale moving bed biofilm process was investigated. also, kinetic analysis of the process with regard to phosphorus and nitrogen removal was studied with different mathematical models. for nutrient removal, the moving bed biofilm process was applied in series with anaerobic, anoxic and aerobic...

A model is outlined for the major biochemical respiratory mechanisms of a conceptualised heterotrophic facultative organism (representing the heterotrophic facultative mass of activated sludge) subjected to four different sets of conditions: steady-state aerobic, steady-state anoxic, steady-state aerobic changed to anoxic, and steady-state anoxic/anaerobic changed to aerobic. Proposals and impl...

In a recent paper, Farmer (2000) offered a novel and stimulating hypothesis for the convergent evolution of endothermy in birds and mammals. She proposed that a high level of nonshivering thermogenesis by adults evolved because of the benefits it provided to their developing embryos. Initially, a higher standard metabolic rate (SMR), and consequently a higher body temperature, served only to in...

this study aimed to evaluate the effect of aerobic training with increased resistance of chest wall movement on ventilatory efficiency and pulmonary functions in untrained students. 18 untrained healthy male university students volunteered to participate in this study and were divided into two groups. they performed aerobic training with 70% – 80% of hrmax, three days a week for four weeks¬. ex...

From a theoretical investigation of the continuity of wastewater organic (COD) and N compounds along the links connecting the primary settling tank (PST), fully aerobic or N removal activated sludge (AS) treating raw and settled wastewater and aerobic digestion unit operations, it was found that the PS characteristics, viz. the biodegradable and unbiodegradable soluble and particulate COD and N...

The difference between maximum metabolic rate and standard metabolic rate is referred to as aerobic scope, and because it constrains performance it is suggested to constitute a key limiting process prescribing how fish may cope with or adapt to climate warming. We use an evolutionary bioenergetics model for Atlantic cod (Gadus morhua) to predict optimal life histories and behaviours at differen...

conclusions this study demonstrated that rt and at are equally effective in reducing hepatic fat content and liver enzyme levels among patients with nafld. however, aerobic exercise specifically improves nafld independent of any change in body weight. results after training, hepatic fat content was markedly reduced, to a similar extent, in both the aerobic and resistance exercise training group...
