near real-time grid-based single-shell model is proposed to correct the ionospheric delay at the user aircrafts. The single-shell model is based on the assumption that the whole ionosphere is compressed at a fixed altitude at 350 km. This assumption may not be appropriate for the Indian region, which falls in the Equatorial Ionospheric Anomaly belt. In this(More)
Materials with the capability to simultaneously support large shear (friction) and normal (adhesion) forces are essential to successful static robotic clinging applications (Zeng et al., 2009). In order to be mobile , these forces must be able to be dynamically controlled with rapid switching between sticky and non-sticky states. Much of the current(More)
Despite the recent progress in and demand for wet adhesives, practical underwater adhesion remains limited or non-existent for diverse applications. Translation of mussel-inspired wet adhesion typically entails catechol functionalization of polymers and/or polyelectrolytes, and solution processing of many complex components and steps that require(More)
The role of friction in the functional performance of biomaterial interfaces is widely reckoned to be critical and complicated but poorly understood. To better understand friction forces, we investigated the natural adaptation of the holdfast or byssus of mussels that live in high-energy surf habitats. As the outermost covering of the byssus, the cuticle(More)
BACKGROUND AND AIMS Postsurgical pain is the leading complaint after laparoscopic cholecystectomy that may delay the postoperative recovery and hence we undertook a prospective randomized trial to analyze the role of flupirtine as a preemptive analgesic for postoperative pain relief in patients undergoing above surgery.
