one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
the coastal region of chabahar gulf with 1113.7km2 area has been located in the southeast of iran. in this research, satellite images of etm+ (2004) were used in order to zoning of sedimentary environments in this gulf. methodology of this research was baesd on synthesis of supervised and unsupervised classifications in gis and envi softwares. based on studies and calculation of oif index, the ...
The objective of this study was to determine whether statistically valid correlations could be shown between enterococcal counts of samples from creek and coastal sites and the presence of two molecular, library-independent markers that specify human and/or sewage pollution. Four hundred ninety samples were collected between August 2007 and April 2009 to determine enterococcal counts and the pr...
Geographical information systems and remote sensing were used to analyze the distribution of the Leishmania infantum-Phlebotomus perniciosus parasite-vector system in relation to environmental features of two opposite sides (coastal and Apennine) of Mt. Vesuvius, an area of intense transmission of human and canine leishmaniasis in southern Italy. Weekly phlebotomine collections were carried out...
Coastal aquatic environments are typically more highly productive and dynamic than open ocean ones. Despite these differences, cyanobacteria from the genus Synechococcus are important primary producers in both types of ecosystems. We have found that the genome of a coastal cyanobacterium, Synechococcus sp. strain CC9311, has significant differences from an open ocean strain, Synechococcus sp. s...

The coastal zone is a complex area, consisting of both the marine and terrestrial environments. It is also home for an increasing number of activities, rights and interests, and according to the UN Atlas of the Ocean 44% of the worlds population. Worldwide countries are realising the need to balance development and exploitation of resources in the coastal zone with environmental and social need...
Hardly any area in the whole world is undergoing such dynamical environmental and social change as the coastal regions of the world. Approximately 20% of the world’s human population live within 30 km of the sea, and nearly double that number live within the nearest 100 km of the coast (IPCC 2001). Furthermore, a big part of economic activities is going on in these areas. In the coastal environ...

Recent literature on migration and the environment has identified key mediating variables such as how migrants extract resources from the environment for their livelihoods, the rate and efficiency of extraction, and the social and economic context within which their extraction occurs. This paper tests these theories in a new ecological setting using data from coastal fishing villages in North S...
