BACKGROUND Laparoscopic sleeve gastrectomy is becoming a popular procedure for the morbidly obese patient. Its utilization as a standalone procedure has good results with weight loss in short- and midterm reports. The aim of this study was to assess our technique and whether it warranted any modifications in the early postoperative period. METHODS Our(More)
Absorption of CW Yb-fiber laser light of 1.07 μm wavelength in water has been measured at different water temperatures and laser intensities. The absorption coefficient was estimated to be 0.135 cm(-1) at 25 °C water temperature, and this was found to decrease with temperature at a rate of 5.7 × 10(-4) cm(-1) °C(-1). The absorption coefficient increased(More)
This paper presents an analysis of a simple biprism-based technique that enables inscription of multiple fiber Bragg gratings (FBGs), each with different Bragg wavelength, into a section of an optical fiber. The method offers a tuning range for Bragg wavelength that is comparable to that of the multiple mirror interferometer method. This has an additional(More)
