Endoscopic surgery is known for its different eye–hand coordination and its learning curves. It encompasses complex and sensitive equipment that requires different maintenance and quality control. Despite the development of dedicated training programs and extensive research justifying the endoscopic revolution, the Dutch Health Care Inspectorate (DHI) [1](More)
BACKGROUND There is an increasing demand for structured objective ex vivo training and assessment of laparoscopic psychomotor skills prior to implementation of these skills in practice. The aim of this study was to establish the internal validity of the TrEndo, a motion-tracking device, for implementation on a laparoscopic box trainer. METHODS Face(More)

A bstruct By means of electrochemical vapour deposition (E VD), it is possible to grow thin (0.5-j pm), dense airconia/yttria layers on porous ceramic substrates. Kinetics of the EVD process, morphology and oxygen permeation properties of the grown layers are investigated. Very thin (-0,.5 tan) layers are grown at relatively low temperatures (700-SOO'C).(More)
One assumes that gravity cooperates with the sperm in the establishment of bilateral symmetry in the embryo, particularly in species with yolky eggs. However, only experiments under genuine microgravity can prove this. May 2nd 1988 on the TEXUS-17 Sounding Rocket, eggs of Xenopus laevis became the first vertebrate eggs ever successfully fertilized in(More)
