all experiments in this study were carried out in a flume which was located in the hydraulic laboratory of technical faculty in guilan university. the wave flume was 12 m long, 0.5 m wide, 0.5 m high and equipped with a wave-producing system and ultrasonic sensors. the objectives of current experimental study are to investigate sediment transport, bed formation and sustainability of sandy beach...

OBJECTIVES To gather enough data from a large scale investigation involving two health authorities, to assess the possible concentrations and routes of exposure and the consequent health implications. To use the data to decide whether a polluted beach should remain open to the public. In Spring 1997, a chemical incident came to light at a beach on the south coast of England when a local residen...

The special environment in beach volleyball playing generates intense stimulation on human bodies, which is pretty helpful in improving the performances of many sports. Meanwhile, the nutrition supply is also showing its critical significance. Due to the altitude environment, a special requirement is imposed on the calorie and nutrition supplied to the bench volleyball players in training. Ther...

The aims of the present study were to establish a detailed and representative record of landing techniques (two-, left-, and right-footed landings) in professional beach volleyball and compare the data with those of indoor volleyball. Beach volleyball data was retrieved from videos taken at FIVB World Tour tournaments. Landing techniques were compared in the different beach and indoor volleybal...

Constraining the exchange of water from the shoreline to the mid-shelf is necessary for the development of accurate and predictive models of nearshore circulation. Ra isotopes, which emanate from sediments and have a variety of half-lives, may be useful in measuring cross-shelf mixing rates. The distributions of Ra isotopes were measured in transects extending perpendicular from the shoreline a...

BACKGROUND Bispectral index (BIS) monitoring reduces the cases of intraoperative awareness. Several factors can alter BIS readings without affecting the depth of anesthesia. We conducted a study to assess the impact of beach chair position (sitting position) on BIS readings. METHODS General anesthesia was administered to 30 patients undergoing arthroscopic shoulder surgery. Patients were kept...

In this work, we will identify important variables that contribute to vehicular movement in an emergency environment. In particular, we formulate and pose the Convoy Routing Problem. We suggest a method for modeling the problem and formulate a precise problem statement that significantly reduces the number of variables under consideration. The difficulty of the proposed problem is examined, pra...

8 Three-dimensional beach features such as crescentic sandbars and rip channels influence beach 9 response to, and recovery from, storm waves, as well as significantly affecting the safety and 10 amenity provided by the surf-zone for beach water-users. In this contribution temporal variations in 11 subtidal and intertidal beach three-dimensionality are observed at a high-energy macrotidal beach...
