many cases of breast cancer is diagnosed by women's themselves during self-examination. The goal of this study was to determine the Relationship between Breast self-examination and Self-esteem, Perceived Benefits/Barriers of Self-efficacy among Health Volunteers of Zarandieh city. This is a cross-sectional Breast Self Examination study and 106 health liaisons of Zarandieh city were involved. Data were collected using a multi-section questionnaire include demographic characteristics, Self-esteem, Perceived Benefits/Barriers of Self-efficacy and Breast self-examination behavior. The data analysis was performed by SPSS software. The rate of breast self-examination was 19 percent. Perceived benefits score among the patients was 46 per cent and perceived barriers score was 83 percent and fear of the test results were the main barriers of self-examination. Regression analysis showed that age, Education level, self-esteem and Perceived Benefits/Barriers, self-efficacy, all together explain 38.5% of breast self-examination variance and among them,pereceived barriers and self-esteem, was the most important predicting factor. The results of this study showed the relationship of Perceived Benefits/Barriers and self-esteem with breast self-examination.

The Zarandieh district is situated approximately 42 km northeast Saveh (Markazi province) and in the northwestern part of the Urumieh-Dokhtar magmatic belt. In this area, mineralization is hosted by Eocene andesitic lava and Oligo-Miocene diorite and gabbroic rocks. According to the geochemical evidence, parental magma of igneous rocks is calc-alkaline, metaluminous and related to continental margin volcanic arcs. Mineralization has been observed as veins, veinlets and brecciated forms in diorite and gabbroic rocks. The main ore mineral is chalcopyrite and associated with pyrite, bornite, oligist, chalcocite, covellite, neotosit, native copper, malachite, azurite, chrysocolla, goethite and limonite. Cu grade in the ore samples are varied from 0.04 to 1.7 % (0.40 % in average). Statistical analyses of geochemical data from mineralized samples by Pearson method displayed that Cu has maximum correlation with Ag, As, Zn, Cd and Pb, respectively. Microthermometry studies of fluid inclusions show that the average homogenization temperature is 195° C and the average salinity of 23 wt% NaCl. The Zarandieh Copper mineralization is closely related to hydrothermal vein copper deposit types.

Correct exploitation of groundwater water resources in any area requires knowledge of geological and hydrological features and structures of that area. Tectonic structures, especially faults, have a major impact on the abundance and quality of groundwater resources. The purpose of this research is to investigate the effect of Khoshkarud fault on the hydrogeological characteristics of the aquifer of Zarandieh Saveh plain. This aquifer is located in the north of Markazi Province. In this research, the changes in the hydrogeological parameters of the aquifer on the sides of the fault line were investigated using the data of the 21-year statistical period (1990 to 2011) and using ArcGIS 9.3 software.The results showed that the highest thickness of alluvium and the maximum transverse electrical resistance equal to 6000 ohm-m2, in the center of the northern block, and lowest thickness of alluvium and the lowest value of transverse electrical resistance It is equal to 500 ohm-m2, located on the southern block, which indicates the direct effect of the fault on the aquifer geometry. In the western region of the Khoshkarud fault and from the beginning of the fault's entrance to the aquifer to the vicinity of Shokhroud city, 23 km long, due to the absence of transverse flow from the fault and the flow direction being parallel to the fault line, the dissimilarity of the water level drop trend in the piezometers opposite and on the sides of the fault in the 48-month time series (2008 to 2011) and the dissimilarity of the distribution map of the concentration of hydrochemical parameters sampled in September 2011 on the sides of the fault, shows that in the western part of the aquifer, the fault acts as a hydraulic barrier, While in other parts of the fault extension, there is a connection.

The studied aquifer is located in Zarandieh Plain of Markazi Province with an area of about 1200 square kilometers. Therefore, in order to identify and protect the optimal use of groundwater resources, a mathematical model of the aquifer was constructed using the MODFLOW code under the 7.1 GMS interface. For this purpose, first a conceptual model is prepared and then a numerical model based on it, based on water level changes using water table statistics of 14 piezometric wells in the region, in a time step of one month for steady state (October 2010) and a period of 12 months (November 2010 Until October 2011) for unstable state, was calibrated manually and automatically. During this stage the initial values of hydraulic conductivity (K) was optimized. At the end of calibration, in the steady state, the RMS amount reached 1.265 meters and in the unstable state, the RMS amount reached 2.145 meters, which is less than the allowable error value of ± 2.5 meters and is acceptable. Also, the validity of the model was performed in another period of 12 months (November 2011 to the end of October 2012) that at the end of validation, the RMS value was calculated to be 2.46 m. Due to the appropriateness of the RMS values of the simulated model, it has the ability to predict the future status of the aquifer. Then, after confirming the accuracy of the model in the validation phase, the future conditions of the aquifer were predicted and the results showed that in the next 3 years, with the continuation of the current trend of harvesting from exploitation wells, in some parts of the aquifer will decline.

In Asyabk Zarandieh town, located in Central Province, sewage discharge is released within 20 meter from arable land of wheat. This research is to determine the concentration of lead and cadmium in contaminated soils, sewage, irrigation water and wheat grown in the area around the town Asyabk and the correlation between them and assessing the potential risks arising from the consumption of wheat grown in the region.

The sampling of drainage and irrigation water, surface soil, wheat was done by random. Lead and cadmium concentrations in all samples were measured. The results were statistically analyzed. Also the zonation map was prepared by GIS software.

Concentration of lead and cadmium in soil samples obtained less than limit permissible but concentration of Cd and pb in wheat obtained exceeded the national standard of Iran. Based on the correlation results between the amount of   lead and cadmium in the wheat samples, soil and irrigation water, there was a strong positive correlation. While there was no relationship between the concentrations of these elements in the wheat samples and the amount of metals in the wastewater samples.

The lack of correlation between the concentration of lead and cadmium in wheat and wastewater showed sewage spread in the region unaffected in the process of increasing the concentration of lead and cadmium in wheat. The main reason of increase Pb and Cd in wheat samples is related to irrigation water (well water). The risk index (HQ) of wheat consumption in the region obtained smaller than 1 for lead and cadmium.
