Concentration of oxygen, methane, and hydrogen were measured in intracolonic gas samples aspirated through the colonoscope at the time of colonoscopy from 46 patients. Of the above patients 20 prepared either with mannitol (n = 10) or with castor oil (n = 10) had the instrument passed to the caecum without air insufflation or suction. After mannitol, mean intracolonic hydrogen concentration (4....

it appears that until bone graft has not achieved 100% success, intraradicular diseases remain controversial and therefore, different treatment plans are suggested for them. treating intraradicular diseases depend on many factors: maxillary molars are more prone to bone loss and have worse prognosis. to assess prognosis more carefully these factors should be considered: 1) bone loss: its apical...

Automatic processes on seismic data using pattern recognition is one of the interesting fields in geophysical data interpretation. One part is the seismic object detection using different supervised classification methods that finally has an output as a probability cube. Object detection process starts with generating a pickset of two classes labeled as object and non-object and then selecting ...

Bubble nucleation is a phenomenon observed in many different physical situations from decompression sickness (DCS) to champagne research. It is of vital importance to the formation of a creamy head that is distinctive to stout beers. As stouts contain a lower quantity of dissolved carbon dioxide than other beers, nitrogen is also dissolved in the beer. This is necessary to produce the smaller b...

We present a study on achieving intense acoustic cavitation generated by ultrasonic vibrations in polydimethylsiloxane (PDMS) based microfluidic devices. The substrate to which the PDMS is bonded was forced into oscillation with a simple piezoelectric transducer attached at 5 mm from the device to a microscopic glass slide. The transducer was operated at 100 kHz with driving voltages ranging be...
