Thermal welding tonsillectomy versus cold dissection tonsillectomy: A systematic review and meta-analysis of randomised controlled trials.

Objectives: To evaluate the efficacy of thermal welding (TW) versus cold dissection (CD) strategies among tonsillectomy patients.

Design And Setting: A systematic review and meta-analysis of randomised controlled trials (RCTs).

Participants: Patients undergoing tonsillectomy.

Planning for a Multi-Well Artificial Recharge Field in Kuwait with the Help of Numerical Modeling.

Kuwait, an arid country, wants to have a reserve of water for emergency use and has planned to create an underground reserve of water through multi-well artificial recharge at Kabd area. Numerical modeling of different recharge-recovery scenarios was carried out to chalk out an optimum strategy for implementation of the project. These scenario runs suggested that apart from the aquifer parameters and the quality of the groundwater and the recharge water, the well spacing and well construction, orientation of the field with respect to the prevailing hydraulic gradient, and the injection and the pumping schedule would determine the overall recovery efficiency of the setup.
