introduction: providing the material for penile reconstruction after release of chordee associated with hypospadias is challenging. we have used the preputial vascularized island flap for this purpose. we report the results of this prospective study. materials and methods: one hundred and twelve boys ranging from 13 months to 12 years of age were enrolled in this study. the location of meatus r...

The economic growth of aquaculture and the dependence of a large growing population on coastal resources have led to coastal degradation and reduced resources. In this paper while realizing the potential capacities of the island systems,  the aquaculture activities of the island are specially discussed  in the framework of Integrated Coastal Zone Management (ICZM). Therefore, in this study, fir...

background: qeshm (26.75n, 55.82e), iran, is 1500 km² island in the strait of hormuz. qeshm is a free trade zone, acting as an important channel for international commerce, and has been the site of much recent development. there is potential risk of stinging ant attacks for residents and visitors that may occur in the island. the aims of this study were to find out the fauna, dispersion, and so...

freshwater lens on small islands may easily be overexploited or polluted due to overdrafts of fresh water by pumping which causes drawdown of the water table a rise or up-coning of the saltwater interface. present study is concerned with using a three-dimensional finite-difference numerical model to simulate the groundwater flow and transport model to predict the behavior of groundwater system ...

The Larsemann Hills range is an ice-free oasis on the Ingrid Christensen Coast of Princess Elizabeth Land, East Antarctica, which includes Bharti Island, Fisher Island, McLeod Island, Broknes Peninsula, Stornes Peninsula, and several other islands, promontories, and nunataks. The Larsemann Hills is an ice-free area of approximately 50 km2, located halfway between the Vestfold Hills a...

first method, samples are collected and the concentration of DON or individual DON components are monitored over time. To measure DON flux rates using 15N tracer techniques. all of the DIN forms (N~ + , NO3 -.and NO2 -) must be removed, and the DON pool must be isolated with a high efficiency. At present. there are three basic approaches used to isolate DON-wet chemistry, ion retardation, and d...

HVDC transmission is more effective and economically cheaper where bulk power is to be transmitted over long distance. Hence the surplus power from a remote place can be exported to the needy place at cheaper rate. The HVDC system require only one transmission wire and the ground return or seawater can be used as an another line. The Lakshadweep Island is located at faraway place from the north...
