Tidal energy is a clean, reliable and available energy that exits vastly. Moreover, it can be offered to most of coastal regions and cities. This clean energy can be used in littoral zones worldwide , together with islands and coasts ofIransuch as Chabahar. Furthermore, from ecosystem point of view, this energy is useful for increasing coral reefs and also using organic materials in diffe...
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 calculat...
The objective of this paper is to introduce a new method for coastlines delineation from high-resolution satellite images automatically. The proposed approach integrates the color histogram analysis for estimating the number of clusters, fuzzy c-partition, and genetic algorithms for optimizing fuzzy c-partition matrix. The imagery is classified into homogenous areas using the proposed fuzzy log...
Mehr housing project is one of the large-scale developmental projects which commenced with the aim of easing housing shortage of the fellow countrymen, while spending a huge amount of financial, physical, and a large number of human resources. Now, measuring the extent of the relative efficiency of this project is an appropriate index for its evaluation. Thus, in the current research, the exten...
Abstract Reverse phase dispersive liquid- liquid microextraction (RP- DLLME) coupled with spectrophotometry is introduced for the detection of total phenol in the muscle tissue of fishes, such as Sphyraena genie, Otolithes ruber, Rastrelliger kangurta, Lutjanus johnii and Barbus Subquin Cunciatus. Phenols in fish tissues were extracted by ultrasonic bath and derivatization with 4- aminoant...
Background and Objectives: Nowadays, the excessive use of antibiotics has caused bacteria to develop new resistant forms, so that discovering bioactive antimicrobial compounds has been considered by researchers. The aim of this study was to evaluate the antibacterial effect of ethyl acetate extract of red algae (Gelidiella acerosa) on some gram-positive and gram-negative bacteria in laboratory ...
a field trial was carried out in the chabahar district of sistan and baluchistan province, southeastern iran on the efficacy of mosquito nets treated with a suspension formulation of deltamethrin (k-o thrin®) against malaria vectors. treated nets were used in three villages, and in the two control villages, one used untreated nets and the other used indoor spraying with deltamethrin (wp 10%), w...
Estimation of siltation depth in harbors and estuaries plays an important role in design of marine structures. In this paper, siltation process at Bushehr estuary as one of the most important water bodies in south of Iran is modeled by so-called MIKE 21 mathematical model. To achieve this, at first a large scale hydrodynamic model calibrated by IRANSIAM registered water levels is developed whil...
Considering the effect of wave on marine activities in Chabahar, different factors influencing the wave height were considered in the present study. For this purpose, the daily data of the year 2007-2011 and hourly data consisting of two month data of the year 2006 were employed. The results of the proposed method were compared with the results of the fuzzy logic based on PSO algorithm. The Mon...
