This study was implemented to prepare a model for soil Salinity mapping using Landsat5 images in several provinces including Bushehr, Semnan, Fars, Kerman and Hormozgan. At the beginning, 50-100 samples from soil surface were taken and sent to the Laboratory. Then in order to evaluate and identify soil Salinity, TM Landsat satellite images and statistical models combined with satellite`s spectral indices were used. After evaluating the accuracy of statistical models using test points, the best model for the study area was selected and the Salinity maps were developed based on the regression model. The results showed a significant relationship between soil Salinity and spectral Index. In Fars province, NDSI Salinity Index had the highest correlation with soil electrical conductivity (0. 35) with a regression coefficient of 66% and RMSE and MBE statistics of 2. 58 and 0. 66, respectively. In Kerman province, the tasseled cap three Index had the highest correlation with soil electrical conductivity (0. 47) with a regression method coefficient of 65%, and RMSE and MBE of 10. 3 and 0. 51, respectively. In Hormozgan province, the results showed high correlation with soil Salinity indicators SI2 level of 72 percent. Stepwise method with R-square of 0. 518 was selected for the Hormozgan province whre the RMSE and MBE were reported to be 2. 5 and-0. 35, respectively. Also in Semnan province, 5 and 7 bands of Landsat showed the highest correlation with soil electrical conductivity (respectively 0. 65 and 0. 75). By using stepwise regression, the linear relation with R-square of 0. 6 was obtained, and RMSE and MBE values were reported to be 2. 83 and-0. 81, respectively.

Background and objectives: Carpal Tunnel Syndrome (CTS) is the most common mononeuropathy encountered in clinical practice. Conventional electro diagnosis studies have been useful in the diagnosis of this condition. The Terminal Latency Index (TLI) is a derived neurophysiological value that adjusts the Distal motor Latency (DL) for the terminal distance and motor nerve Conduction Velocity (CV).Several studies have suggested utility of the median TLI for diagnosis of CTS.The goal of this study is to evaluate prospectively the sensitivity of the median TLI in the diagnosis of CTS and compare it with other electrodiagnosis techniques.Material and Methods: This study was done on 111 patients as CTS group & 62 healthy subject as control group. In all groups five selected tests of electrodiagnosis were done and all of them were compared with TLI sensitivity.Results: The mean TLI was 0.3±0.05 in the CTS group and 0.42±0.03 in the control group. The sensitivity of TLI was 73% The TLI wasn't statistically better than the other tests, but in three cases from the CTS group, the TLI was the only abnormal test.The 7 and 14 cm method had meaningful sensitivity in contrary to other tests.Conclusion: The sensitivity of TLI has no meaningful difference with other routine electro diagnostic tests in diagnosis of CTS.The median TLI is a useful but not more sensitive electrodiagnostic test for CTS.

Introduction: Three methods of OCRA Index, Strain Index (SI), and ACGIH HAL have been proposed for the assessment of risk factors of upper limb musculoskeletal disorders. Investigating the correlation and consistency of these three methods are of prominence importance in the workplaces. Thus, this study aimed to determine the correlations of the results of the above mentioned methods. Materials and Methods: In this cross-sectional study, a total of 150 tasks were studied in four industries. For each task, a video taping of a full working cycle was prepared and evaluated according to the instructions of each method. The level of risk exposure to musculoskeletal disorders was analyzed with correlation and Kappa agreement coefficient tests using SPSS (version 16) and R software packages.Results: The correlation between the results of risk assessments of OCRA and SI methods for right and left hands were acceptable and equal to 0.751 and 0.726, respectively (p<0.001). Meanwhile, the coefficients of agreement between OCRA and HAL methods for left and right hands were 0.526 and 0.595, respectively.Conclusion: These findings partly confirmed the agreement between the methods of risk assessment. The origin of this partial agreement can be the number and type of variables and their impacts on the final score of the methods.

Irrigation scheduling with Salinity and stresses, is much more difficult than Full irrigation. Using canopy temperature for plants irrigation scheduling is one of the methods that have been attention by many researchers. On of the usual method is presented by Idso. This research intends to investigate irrigation scheduling of summer maize using crop canopy temperature in Ahvaz climate (2013-2014) using surface irrigation with two levels of Salinity irrigation water (S1=2.5 ds/m, S5=5 ds/m).Crop water stress Index (CWSI) is calculated for the two treatments. The experiment had three replications. With due to the obtained results, The CWSI for the two treatments S1 (minimum Salinity) and S5 (maximum Salinity) in September 14 and October 15 were 0.26 and 0.22. Upper baseline for the S1, in September and October are 5.05 C0 and 4.975 C0 respectively. For the S5 treatment the upper baselines in September and October were 2.85 C0 and 2.60 C0 respectively. Lower baseline also were calculated for the treatments. That was represented It is found that the S1 lower baseline is lower than the S5 treatment. This is due to the S5 treatment was effected By tension more than the S1 treatment. By using of measured data for scheduling irrigation maize in October and September with surface irrigation methods, some equations were determined. By using of the equations and comparing measured with the calculated canopy and air temperature, time of irrigation can be detected.

Introduction: Salinity is one of the most important tensions in global agricultural production. About 20% of the irrigated lands are facing Salinity problems in arid and semi-arid regions of the world, and Salinity in these areas is increasing. In Iran, the Salinity is about 44. 5 million hectares, which has varying degrees of Salinity and alkalinity (Banaei, et al., 2005). Selection of salt tolerant genotypes in farmer conditions is a practical and dealing ways in using saline water and soil. Millet cultivation in Iran has a long history and according to the short growth period, is able to feed forage in conditions where other sources of forage are not available. The cultivated area in Iran is about 10, 000 hectares (Aaron, 2006). According to recent studies, it is possible to develop plant cultivation in all regions of the country. The area under cultivation of this plant in the south khorassan province is about 1000 hectares and the cultivation of this plant has long been rooted in the culture of farmers in this area (Bina, 1993). According to the adaptability of this plant to unfavorable environmental conditions, soil poverty and environmental stresses that are characteristic of arid and semi-arid regions such as South Khorasan. One of the easiest ways to identify and selection of resistant genotypes is explosion to stress and selection the genotypes that tolerate these conditions better than the others. Materials and Methods: In order to evaluation of salt tolerance in foxtail millet genotypes, two separate experiment with 15 genotypes in saline and none-saline conditions arranged in randomized complete block design with three replications conducted in two years of 2012 and 2013 at the Research and Education Center of Southern Khorasan. Combined analysis of variance showed that salt stress lead to a significant reductions in days to heading, days to maturity, plant height, panicule length, number of panicule per plant and thousand seed weight. In the end, after determining the grain and forage yield in stress and non stress conditions, MP, GMP, TOL, HARM, STI and SSI indices were calculated and using SAS software, correlation between the indices with grain yield and The dry forage was examined and using the SigmaPlot software, the three-dimensional distribution chart of each sample was plotted in A, B, C, and D ranges. Results and discussion: Millet seed yield and dry forage yield in saline condition decrease about 40 and 38 percent, respectively. Genotypes number 15-118, 15-24 and 15-120 with averages of 3827. 8, 3805. 1 and 3803. 2 kg/ha had the highest and number 15-80 with 1977. 2 kg/ha had the lowest two year averages of yield, respectively. Results of correlation of seed yield and dry forage yield of millet genotypes in saline and none-saline conditions with tolerance and sensitivity indices revealed that STI, MP and GMP are the best indices for selection and recognition of salt tolerance genotypes of foxtail millet. Genotypes numbers of 15-24, 15-76, 15-118 and 15-120 indentified as the most tolerant genotypes to Salinity stress on the basis of 3D scattering graph.

Introduction: J.E.Hirsch introduced H Index to scientometric domain, representing actual scientific profitability quality of a researcher’s publications; and is equal to effective Index for researchers. Literature review: Studies showed that documents database have provided different H scores for each researcher and for different scientific fields. Despite the utmost advantages of H-Index it also have some flaws such as need to use complementary indices such as m, r, g Index. Conclusions: The strength point of H Index, is its ability to use in limited levels which is an complementary for other bibliomeetric exist Indexes. This Index, with others, could be a suit Index to improvement scientific levels for researchers, scientist, and scientific board members.

More than 22% of the world's agricultural land is saline, and this trend continues to increase with climate changes. Salinity stress causes leaf color change, osmotic stress, ionic toxicity, prevents growth, photosynthesis and plant performance. Due to their size less than micron, metal nanoparticles have a great absorption and transmission power in plants. Salinity stress is a major problem in hot and dry areas under tomato cultivation. For this purpose, investigating the mutual effects of the size and type of zinc oxide and iron oxide nanoparticles on the improvement and change of growth and increasing the resistance to salt stress in tomato plants of the early urbana variety were carried out in the form of a completely randomized and factorial design with 4 replications, at a significant level of 5%. In this research, zinc oxide nanoparticles in 25 and 50 nm sizes, iron oxide in 25 nm sizes and sodium chloride in 0 and 75 mM levels were used. Nanoparticles and Salinity treatments were both applied to the plants. The results showed that salt stress led to a decrease in plant growth parameters such as shoot and root length, leaf area, RWC, ion leakage. Also, NaCl led to an increase in the accumulation of prolin and other aldehydes, sodium, iron and zinc. The application of nanoparticles had a slight effect in stress-free conditions, but in stressed conditions, these two nanoparticles alone and especially in combination neutralized the effect of Salinity and reduced the damage caused by Salinity stress.
