Background: The incidence of complications of laparoscopic cholecystectomy has increased dramatically since the introduction and widespread use of laparoscopic cholecystectomy in 1990. Bile duct injuries are among the most important complications of this approach. Methods : From January 1998 to January 2002, a total of 155 laparoscopic cholecystectomy were performed at the Loghman Medical Cent...
Membrane reactors are currently under extensive research and development. Hardly any concept however is realized yet in practice. Frequently, forgotten as membrane reactors are electro-catalyic membrane reactors where electrodes perform chemical conversations and membranes separate the locations of conversion. In this chapter we extensively describe a technology where the membrane itself is cat...
In a previous paper, we proposed that QCD gas may be possible candidate for the general theory of gravity (GR) ether comprised ud~du~ exotic mesons. A method to determine effective mass meson and Friedmann-Robertson-Walker (FRW) metric scale factor equation state dimensionless parameter, w, by measuring pseudo-first order ? decay rates expected inversely proportional atmospheric density was giv...
Anaerobic treatment is applied extensively of removal of organic pollutants (COD) from wastewater. It is more competitive than aerobic treatment in applications where the quantity of COD to be removed is large. The major fraction of COD is converted to useful methane gas, and only a small fraction becomes waste sludge. The COD loading rate of anaerobic reactors is higher than that of aerobic re...
