This resaerch was conducted in order to study the importance of economic, social and touristic to the Anzali wetland, north of Iran. Data was collected through "field research" and "documentary research". Nominal scales, Likert and Guttman scales were used for the compilation of questionnaires. Findings of the present research indicate that the variation of population growth rate in the periph...

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...

A new computational method for creating all-hex meshes of thin-walled solids is presented. The proposed method creates an all-hex mesh in a three-step process. First, a tet mesh of the target geometric domain is created, and a layer of prism elements is inserted on the boundary of the mesh. Second, a sequence of novel topological transformations and smoothing operations is applied to reduce the...
