The equilibrium shape of a monatomic strained island on a substrate depends on the step free energies and the difference in surface stress between the island and the substrate. For small island sizes the step free energies dominate, resulting in compact islands. Beyond a critical island size, however, the strain energy becomes dominant and the island maximizes its perimeter, resulting in elonga...

Nuclear markers such as microsatellites have allowed the identification of conservation and management populations of the Hawksbill turtles. In present study, eight microsatellite loci were studied. 60 samples of hawksbill turtles. flipper from Shidvar and Hormuz Islands have been surgically removed and preserved in 20% DMSO buffer. DNA was extracted using DNP KIT and amplified by PCR methods. ...

this study was conducted to investigation and determine of cadmium (cd) concentration in the liver of platycephalus indicus (flathead) in minab, qeshm island and khamir port (persian gulf). moreover, the effect of season (winter and summer) and sex (male and female) on cd concentration in flathead were investigated. cd concentration sampling was done in two station (minab, qeshm island and kham...

The formation of an island circulation is investigated both theoretically and numerically in light of the dynamics of coastal Kelvin waves and Rossby waves. An island circulation is formed in three stages. First, the direction of the circulation is initiated by the coastal Kelvin wave; second, the transport of the circulation is established by the short Rossby wave dissipated against the easter...

world's coastlines are the most dynamic natural environments and diverse extraordinary and unique processes are active in this area. one of results of these processes is the formation and evolution of alluvial fans and delta. the studied areas include hormoz strait coastal, shour, jalaby and hassan-langi river delta which in the form of a strip with a varying width covers the areas from th...

We generalize the level set approach to model epitaxial growth to include thermal detachment of atoms from island edges. This means that islands do not always grow and island dissociation can occur. We make no assumptions about a critical nucleus. Excellent quantitative agreement is obtained with kinetic Monte Carlo simulations for island densities and island size distributions in the submonola...

Island systems generally have fewer species than continental areas due to their small size and geographical isolation. Low island diversity reduces the possibility of exportation of island lineages and island systems are not thought to have a major influence on the build-up of continental diversity. However, the view that islands represent the end of the colonization road has recently been chal...

We present an island model that uses different representations in each island. The model transforms individuals from one representation to another during migrations. We show that such a model helps the evolutionary algorithm to escape from local optima and to solve problems that are difficult for single representation EAs. We illustrate this approach with a two population island model in which ...

The purpose of this review is to survey the floristic, ecological and historical research about the Erie Islands and its flora since 1976 and to describe efforts to conserve Erie Island habitats. Island location records, surveys and multi-island inventories reveal that over 1,000 vascular plant taxa are known from the Erie Islands and new records continue to be found. Alvar habitats, rare globa...

The effect of the Big Island of Hawai’i on tropical cyclone (TC) track and structure is investigated using the Weather Research and Forecasting (WRF) model. The high (;4000 m) mountains of the Big Island modulate lower-tropospheric flow in such a way that it can influence TCs hundreds of kilometers away from the island. When a TC approaches from the east, the blocking of lower-tropospheric flow...
