OBJECTIVE Bithermal caloric tests are among those most commonly used in vestibular function studies and require a properly systematized approach. Irrigation sequence varies between laboratories. Our objective is to study the effect of irrigation sequence on the percentage of vestibular paresis. MATERIAL AND METHOD We analysed 1214 records, 77.51% cold to hot sequences (C-H) and the rest hot t...

Wound debridement refers to the removal of necrotic, devitalized, or contaminated tissue and/or foreign material to promote wound healing. Surgical debridement uses sharp instruments to cut dead tissue from a wound and it is the quickest and most efficient method of debridement. A wound debridement simulator can ensure that a medical trainee is competent prior to performing a procedure on a gen...

Solar-powered agricultural irrigation is an attractive application of renewable energy. However, to be practical it must be both technically and economically feasible. Here, a method is presented for calculating the feasibility of photovoltaic-powered (PVP) irrigation. The feasibility is expressed as a function of location, which includes climate data, aquifer depth and cost, including local po...

Center pivots are the primary method of irrigation across the U.S. Great Plains. Center-pivot irrigation is also the fastest growing method of irrigation in the U.S. and around the world. Pivots have the potential to be very efficient and uniform if sprinkler devices are properly selected for local field conditions. New water application devices provide for selection that minimizes runoff and c...

infiltration in furrow irrigation is 2-d which depends on both time and surface characteristics at which infiltration occurs. however, in many furrow irrigation models, infiltration is determined as a function of infiltration time opportunity, assuming the variation of weted perimeter is low along furrow. in order to compare the proposed asumptions, two zero-inertia furrow irrigation models wer...

Infiltration phenomenon, has a direct impact on rainwater harvesting in fields under irrigation. In order to solve this problem (reduced infiltration and increased runoff), a few strategies can be suggested. Taking long-term decision for increasing the efficiency of irrigation should be strongly suggested. At the same time, ways in which customized irrigation is optimized must be studied. An ol...

Introduction: Vasectomy is the safest and most reliable method of all the contraception methods, but azoospermia is not achieved immediately by this method. We decided to determine whether irrigation of the vas deferens with sterile water or hypertonic saline solution irrigation during vasectomy would reduce the time needed to obtain azoospermia. Materials and Methods: A total of 126 fertile me...

OBJECTIVE The antiseptic effect of gastric irrigation before endoscopic submucosal dissection (ESD) has not yet been reported. The aim of the randomized prospective study is to evaluate the antiseptic effects of gastric irrigation of saline solution before ESD by evaluating bacterial count. METHODS This prospective randomized controlled trial included 50 patients diagnosed with early gastric ...

Salinization and secondary salinization often appear after irrigation with saline water. The Taklimakan Desert Highway Shelterbelt has been irrigated with saline ground water for more than ten years; however, soil salinity in the shelterbelt has not been evaluated. The objective of this study was to analyze the spatial and temporal distribution of soil moisture and salinity in the shelterbelt s...
