a pilot anaerobic filter was used to remove cod from babolsar fiberboard production wastewater. the anaerobic filter was packed with ceramic packings and operated at different organic loading rates of 2.4 and 8 kg cod/m3 /day, in 20, 10 and 5 days hydraulic retention time (hrti), respectively. the reactor achieved cod removal of 80.3%, 81% and 79% for hrt 20, 10 and 5 days, respectively. in add...

up flow anaerobic sludge blanket (uasb) reactors have been increasingly used for industrial wastewater treatment. because of existing problems in startup step of these reactors, in this research the startup of a uasb in pilot scale and room temperature condition was studied. the total height of uasb reactor was 270 cm and effective height was 240 cm. diameter of the reactor in lower part was 20...

background and objectives: anaerobic bacteria are recognized as important pathogens in surgical infections. however, they are the most overlooked microorganisms by the clinic and the laboratory because of the tedious culture techniques with longer turn-around times. the study was aimed to analyze the frequency of anaerobic bacterial surgical infections and their predisposing factors. materials ...

anaerobic bacteria are well known causes of sepsis in adults but there are few studies regarding their role in neonatal sepsis. in an attempt to define the incidence of neonatal anaerobic infections a prospective study was performed during one year period. a total number of 400 neonates under sepsis study were entered this investigation. anaerobic as well as aerobic cultures were sent. the pati...

Improving anaerobic performance and anaerobic power is the critical aspect on successfully in competitions for many athletes. The purpose of current research was to investigating the effect of various pre-competitions warm-up on anaerobic performance. It has been shown that, differences pre-competitions activity may effect on anaerobic and explosive performance. Effect of general warm-up, witho...

the main theme to conduct present research work was to evaluate the effect of anaerobic granular sludge in degradation of two azo dyes. the study was evaluated in batch experiments where anaerobic and aerobic conditions were integrated by exposing anaerobic granular sludge to oxygen. under these conditions, the azo dyes were reduced, resulting in a temporal accumulation of aromatic amines. subs...

materials and methods one hundred ssis specimens were obtained by needle aspiration from purulent material in depth of infected site. these specimens were cultured and incubated in both aerobic and anaerobic condition. for detection of antibiotic susceptibility pattern in aerobic and anaerobic bacteria, we used disk diffusion, agar dilution, and e-test methods. results a total of 194 bacterial ...

Introduction: The concentration and action of ascorbic acid in the central nervous system as a vitamin and also a neuromodulator have exercise-induced fluctuations. The present study was conducted to evaluate the effects of anaerobic exercise alone and associated with the consumption of ascorbic acid as a non pharmacological treatment for reducing seizures and increasing seizure thresholds. ...

Background. Exercises with different intensities can cause changes in immune system factors and hormonal acute response. These changes may exceed the permissible limitations and weaken the system. Objectives. The purpose of this study was to compare the effect of an intensity aerobic and anaerobic training session on acute hormonal response and immune system factors. Methods. A total of...
