in the past 25 years, rising of the caspian sea level, part of a natural treat to the sea, has inundated and destroyed many buildings and arable lands and threatened many inhabitations in coastal areas. the main reason for these damages is that the law-setback has lost its efficiency and human activities have proceeded seaward. the goal of this study is to introduce a proper setback line for th...

Three ways in which near-boundary processes influence the ocean are reviewed. In the first topic, solutions for the flow and stratification in a situation where mixing dies away slowly away from a sloping boundary can show a sensitivity to the eddy Prandtl number, emphasizing the importance of studying the mixing of momentum as well as buoyancy. In the second topic, the importance of near-bound...

many studies since 1977, in the southern coast of caspian sea revealed that the law-setback and low-lying coastal zone have been severely and increasingly impacted by rising sea-level. this rising continued until 1995. the rate of rising was nearly 13cm per year in this period (1977-1995). the general concept of setback determination is tended to introduce a buffer area between human activities...

Large tracts of tropical rainforests are being converted into intensive agricultural lands. Such anthropogenic disturbances are known to reduce species turnover across horizontal distances. But it is not known if they can also reduce species turnover across vertical distances (elevation), which have steeper climatic differences. We measured turnover in birds across horizontal and vertical sampl...

in the early years, the rising of the sea level, which is a part of natural treatment, destroyed many buildings, arable lands, residential and commercial areas. it seems that the main reason of these destructions is the diminishing of the legal setback efficiency and the proceeding of human activities. the aim of this study is to introduce the appropriate setback for southern coast of caspian s...

The morphology, stress, and composition distributions of the crosshatch pattern on a SiGe film grown on a Si~001! substrate using a low-temperature Si buffer are studied by atomic force and Raman microscopies. Crosshatching is not related to composition fluctuation regardless of the stress undulation associated with strain relaxation in the SiGe film. The crosshatch morphology arises from verti...

Background: Anatomical and histological studies of the spinal cord have always garnered anatomists’ attention because of their high importance in various fields of veterinary medicine, zoology and behavioral science. OBJECTIVES: This work was conducted to understand the detailed histomorphometric aspects of the spinal cord of Indian gray mongoose (Herpestes edwardsii). METHODS: Six adult Indian...

Heat-carrier heating device is an important part of biomass pyrolysis oil equipment. In particular, the application of vertical heat-carrier heating device can improve the rate of biomass pyrolysis. In this article, we will analyze the vertical carrier heating device based on FLUENT software and model the temperature field and velocity field of hot gas and carrier so as to draw a conclusion tha...
