Considering the ease of isolation and high expansion potential of pulp stem/progenitor cells isolated from wisdom and primary teeth they have been implicated as the most reliable autologous cell source in dental tissue engineering. Meanwhile, different isolation methods have remarkable impacts on the expansion potential of adult stem cells. In enzymatic digestion method extracted teeth as denta...

in this study, deinkability of old newspaper by conventional method and the effect of washing, flotation and combined washing/flotation processes were investigated on optical and superficial properties of the produced papers. the results from measuring of the optical and superficial properties indicated that using chemical treatment time of 20 minute and one stage washing resulted the papers wi...

OBJECTIVE There is no general agreement regarding the use of the first or second drop of blood for glucose monitoring. This study investigated whether capillary glucose concentrations, as measured in the first and second drops of blood, differed ≥ 10% compared with a control glucose concentration in different situations. RESEARCH DESIGN AND METHODS Capillary glucose concentrations were measur...

We present the results of experimental investigation of ultrasonic washing of textiles. The results demonstrate that cavitation bubbles oscillating in acoustic fields are capable of removing soils from textiles. Since the washing performance is mitigated in a large washing bath when using an ultrasonic transducer, we propose a novel washing scheme by combining the ultrasonic vibration with a co...
