We tested whether the reduction of metabolic rate (MR) in hibernating Cercartetus nanus (Marsupialia, 36 g) is better explained by the reduction of body temperature (Tb), the differential (ΔT) between Tb and air temperature (Ta), or thermal conductance (C). Above the critical Ta during torpor (Ttc) of 4.8 ± 0.7°C, where the Tb was not regulated, the steady-state MR was an exponential function o...

conclusions retrograde laparoscopic appendicectomy using single polymer clip makes easy access to operating in complicated and non-complicated appendicitis. results four patients (15.4%) were converted to open surgery; three patients in group i and one in group ii. four patients developed postoperative complications; three patients in group i and one in group ii. operative time was less in grou...

A theoretical model of nuclear spin conversion in molecules controlled by an external electromagnetic radiation resonant to rotational transition has been developed. It has been shown that one can produce an enrichment of spin isomers and influence their conversion rates in two ways, through coherences and through level population change induced by radiation. Influence of conversion is ranged f...

formed by Dr. Jacobs in 1991, several randomized trials have confirmed the feasibility and the safety of laparoscopic colorectal surgery. However, some concerns about this procedure still need to be addressed. One of the major concerns is regarding intra-operative conversion from laparoscopic to open surgery. Conversion rates from 2% to more than 40% have been reported by several investigators....

1. Plasma androstenedione, plasma oestrone and the conversion of plasma androstenedione into oestrone were measured in 19 post-menopausal women without fractures (six of them oophorectomized) and 18 with vertebral or femoral neck fractures (four of them oophorectomized). 2. In the series as a whole, the main determinant of the plasma oestrone level was the plasma androstenedione concentration. ...

Objective: Evaluate the predictive value of body mass index (bMI) for hospital length-of-stay, surgical conversion, and postoperative complications in laparoscopic colorectal surgeries. Methods: retrospective analysis of 152 patients undergoing laparoscopic colorectal surgery. Patients were divided into two groups: group I (bMI≤30) and group II (bMI>30). the average hospital length-of-stay and ...

The conversion of digital signals from a given sampling rate to a second, arbitrary sampling rate, with both sampling rates derived from independent clock generators, is revisited. A general approach to arbitrary sampling rate conversion is presented from which two efficient realisations are deduced. The computational expenditure of both realisations is derived under the restriction of finite c...
