STUDY DESIGN Experimental laboratory study. OBJECTIVES To investigate the effect of inflation of the air bladder component of the AirLift PTTD brace on relative foot kinematics in subjects with stage II posterior tibial tendon dysfunction (PTTD). BACKGROUND Orthotic devices are commonly recommended in the conservative management of stage II PTTD to improve foot kinematics. METHODS AND MEA...

Limited available water resources have rendered wastewater reuse an important issue to specialists in most developed countries, today. The current study works on membrane filtration for treatment of industrial wastewater. By comparing the two methods of membrane bioreactor (MBR) and hybrid membrane electro bioreactor (MEBR) processes, it finds that earlier fouling in the membrane occurs in the ...

The investigations were made in a loop bioreactor, where biomass was immobilized in the ceramic carrier. The influence of the internal circulation rate on the biodegradation efficiency of brewery wastes by immobilized biomass and on production of surplus sludge was examined. The rates of the internal circulation were 12, 38, 50 dm·h. The experiments were performed at constant loading rate of th...

This paper deals with the vibrational control of a recycled bioprocess, which takes place into a Continuous Stirred Tank Bioreactor (CSTB). The classical control techniques for bioreactors necessitate measurements of states and/or disturbances. However, the bioprocesses are systems that require costly and difficult on-line implementation for sensors. Vibrational control is a non-classical open-...

Using a single symmetric relay feedback test, a method is proposed to identify all the three parameters of a stable second order plus time delay (SOPTD) model with equal time constants. The conventional analysis of relay auto-tune method gives 27% error in the calculation of ku,. In the present work, a method is proposed to explain the error in the ku calculation by incorporating the higher ord...

To achieve large-scale low-cost ex vitro acclimatization of Siberian ginseng plants, heart- and torpedo-shaped secondary somatic embryos (SEs) induced from germinated SEs on agar medium were collected and then inoculated to 10-l bubble column bioreactor, respectively. For plantlet conversion, inoculation of torpedo-shaped secondary SEs was more effective than heart-shaped SEs. TS2 (culture of t...
