We adapt the level set method to simulate the growth of thin lms described by the motion of island boundaries. This island dynamics model involves a continuum in the lateral directions, but retains 1 atomic scale discreteness in the growth direction. Several choices for the island boundary velocity are discussed, and computations of the island dynamics model using the level set method are prese...

The radial structure of the shear Alfvén wave continuous spectrum is calculated inside the separatrix of a magnetic island. We find that, within a magnetic island, there is a continuous spectrum very similar to that of tokamak plasmas, where a generalized safety factor q can be defined and a wide frequency gap is formed, analogous to the ellipticity induced Alfvén eigenmode gap in tokamaks. Thi...

The Beringia region of the Arctic contains 2 colonies of lesser snow geese (Chen caerulescens caerulescens) breeding on Wrangel Island, Russia, and Banks Island, Canada, and wintering in North America. The Wrangel Island population is composed of 2 subpopulations from a sympatric breeding colony but separate wintering areas, whereas the Banks Island population shares a sympatric wintering area ...

Mismatch of territories under authority of local governments with urban-regional activity domains, on one hand, has caused numerous problems and, on the other hand, has hindered taking maximum advantage of regional capacities and partial and competitive advantages. Hence, application of a new regionalism approach, which focuses on shared planning and management by all stakeholder groups within ...

Rocky shores are one of the most important habitats of marine environment in coastal areas. They host marine organisms including seaweeds because of existence of strong and stable substrate for their growths. Intertidal rocky shores are a prominent feature on coastal areas of Qeshm Island located at the northern part of Strait of Hormuz. In order to study biomass of seaweeds on rocky intertidal...

Severe Tropical Cyclones associated with surges frequently hits the coastal region of Bangladesh. For a reliable hydrodynamic model to simulate the severity of such cyclones, it is necessary to incorporate the meteorological and hydrological inputs properly. In order to incorporate the coastlines and the island boundaries properly in the numerical scheme a very fine grid resolution along the co...

abstract in the 7th and 8th centuries of hijri, kish island had been the maritime trade center of the persian gulf under the reign of  bani gheisar government, and any changes in this area has affected the neighboring areas and further lands. the objective of this essay is to study the economic changes of kish island and its excellent position in the maritime trade of the persian gulf, oman sea...

having special ecological condition, kish island has a restricted range of native species of ornamental plants. expansion of urban green space in this island is great of importance due to its outstanding touristy position in the south of iran. the purpose of this study was to investigate the growth and development of groundcover plants planted in four different regions of kish island and to rec...

Introduction: In the past 10 years, a declining trend was seen in the annual parasite incidence (API) of malaria in the Car Nicobar Island. For the past few years, the API in the island has been below one. Car Nicobar Island is struggling with malaria cases reported to have been brought from other, malaria-endemic islands. Methods: The movements of people...
