Introduction: Chemical fertilizers are one of the most important factors that pollute the environment. Chemical fertilizers can cause air, soil, surface and underground water pollution and cause irreparable damage to the environment. Among the chemical fertilizers, nitrogenous fertilizers have the largest amount of consumption and can be affected by the oxidation and reduction process and affect the environment the most. So far, many methods have been presented to recommend chemical fertilizers, but all these methods are qualitative and cannot calculate the quantity of fertilizer required by the plant. The Integrated Plant and Soil System (IPSS) was first described in 2019. In this method, the amount of elements needed by plants is calculated quantitatively. Materials and Methods: There was a significant correlation between nitrogen of saturated soil extract and nitrogen of plant organs, and the highest correlation was observed between the nitrogen of young leaves and the nitrogen of saturated soil extract. Also, the highest correlation was between the nitrogen of young leaves and other plant organs. Organs of plants whose nitrogen had a significant correlation with soil nitrogen were selected and multivariate regression equations were determined between them and soil saturated extract nitrogen. By simplifying them, two equations with two variables were obtained, according to which the required fertilizer can be calculated. Results and Discussion: There was a significant correlation between nitrogen of saturated soil extract and nitrogen of plant organs, and the highest correlation was observed between the nitrogen of young leaves and the nitrogen of saturated soil extract. Also, the highest correlation was between the nitrogen of young leaves and other plant organs. Organs of plants whose nitrogen had a significant correlation with soil nitrogen were selected and multivariate regression equations were determined between them and soil saturated extract nitrogen. By simplifying them, two equations with two variables were obtained, according to which the required fertilizer can be calculated. Conclusion: The results of this research are two bivariate regression equations, based on which the amount of fertilizer required by plants can be calculated quantitatively and accurately, and the environment can be protected from the risk of chemical fertilizer contamination. This method can be used for all elements and plants in hydroponic and soil cultivation systems. Manuscript profile

Today, neuroscientists are interested in discovering human brain functions through brain networks. In this regard, the evaluation of dynamic changes in functional connectivity of the brain regions by using functional magnetic resonance imaging data has attracted their attention. In this paper, we focus on two model-based approaches, called the exponential weighted moving average model and the dynamic conditional correlation model, to estimate the dynamic correlation between the two brain regions. Initially, the performance of these two models is evaluated using two new simulations. According to the results, in these simulation studies, the dynamic conditional correlation model has better performance than the exponential weighted moving average model. Therefore, a dynamic conditional correlation model is used to estimate the dynamic functional connectivity of two brain regions (the anterior cingulate cortex and the posterior cingulate cortex) for three Iranian addicted to methamphetamine in a resting state functional magnetic resonance imaging. The dynamic conditional correlation model has a good performance in assessing the dynamic functional connectivity of these addicted to methamphetamine. In addition, the dynamic functional connectivity varies between subjects. Manuscript profile

The purpose of this article was to measure systemic risk and the impact of fundamental variables on it in the country's banking system. In this regard, information from the period of 2010-2019 was used. In the first part, systemic risk indicators were estimated, then the impact of the fundamental variables of the country's banking system and financial stability was evaluated. In order to estimate the model, the final expected deficit method (MES) and panel data were used. The systemic risk index in this research is obtained from the calculation of the degree of leverage (debt size), market size and expected final deficit (MES) in order to finally be able to model the factors affecting it.In this research, first of all, different types of systemic risk assessment models have been evaluated according to the forecast error, and then, with the better selected model, the relationship between systemic risk and the important ratios of the country's banking system has been evaluated. The results showed that there is a significant positive relationship between independent variables such as inflation rate, external debt, government debt, liquidity growth, non-current facility rate, debt ratio and the ratio of book value of equity to market value, and independent variables such as profitability There is a significant negative relationship between the total index of the stock exchange, the growth rate of GDP and return on assets with the systemic risk index among the country's banking system.

One of the features of a financial market, the stock market in particular, is its affectability from other financial and non-financial markets. regarding the importance of this issue, the present study aimed at investigating the dynamic conditional correlation (DCC) between the returns on the domestic and foreign assets in monthly data (oil, industry, exchange and base metals including total, copper, steel) and returns on the stock price index in Iran during March 2001 to April 2017 using the DCC-FIAPARCH approach. The obtained results indicated a statistically significant and positive DCC coefficient difference between the metals, industrial products, and copper returns with the stocks returns. Consequently, it is not possible to put each of these assets with the stocks in an identical situation (purchase or sale), but instead they should be always placed in opposite situations for the purpose of risk control. However, with regard to other assets, the DCC was not significant; accordingly, the assets can be placed in the investment portfolio together with the stocks although the presence of such assets in the given portfolio did not help to reduce the portfolio risk.

The purpose of this study is to model the default risk correlation in the financial network based on the reduced model. In this study, we focus on the spread of default in the financial network and examine the effect of financial system heterogeneity on the stability of the financial system, and finally, by implementing intervention policies, we offer suggestions to reduce risks and rebuild the network. This research is among the applied researches. The statistical sample of the studied information is 407 companies listed on the Tehran Stock Exchange in the period of 1393-1398. In order to test the relationship between variables and the significance of the model, regression analysis and MATLAB software was used for modeling. Research findings show that the companies that have the most contact with network members will have the greatest impact on network instability. The results showed that the increase in the dispersion of interdependencies of receivables and liabilities, to the depth of 5 relationships in companies, has a negative effect on the stability of the financial system and the high variance of positions and the degree of financial epidemic by increasing both epidemic range and probability Manuscript profile

This study aims to investigate the relationship between crude oil price returns and stock market index returns of an exporter (Iran) and an importer (Turkey). Using daily data of West Texas Intermediate (WTI), Brent crude oil spot prices, and one-four month futures prices for the WTI; Tehran Stock Exchange Price Index (TEPIX), Tehran Stock Exchange Dividend and Price Index (TEDPIX), the Dividend and Price Index for the Istanbul Stock Exchange gathered during the period of 2000-2010; the relationship is analyzed by two models of the Constant Conditional Correlation (CCC) and the Dynamic Conditional Correlation (DCC). The findings reveal that the DCC is predominant over the CCC for Turkey, which means there is a non-constant conditional correlation. In contrast, the findings show the predominance of CCC for Iran. Among the spot markets, stock market volatility is better defined by the Brent than the WTI. For futures markets of the WTI, a better relationship with longer maturity confirms the financial markets as being long-term. Finally, no evidence is found for one- or bi-directional volatility spillovers (interdependencies) between the markets. Manuscript profile

Background and Objective: Relationship between agricultural use area and fertilizer consumed with changes in groundwater nitrate concentrations is one of the direct methods of agricultural use on nitrate concentration and groundwater inflammation in each region that can manage managers in proper management. Help ground water resources. The purpose of this study was to investigate the relationship between changes in agricultural and chemical area of consumed on the increase in nitrate concentrations in groundwater sources in Ray plain. Research method: In this study, Landsat 5 and 8 satellite images for the years 2008, 2011, 2014, 2017 and 2020 were used to monitor land use changes. After processing the images, the area of agricultural land was calculated. According to the statistics obtained from the amount of chemical fertilizer consumed and the qualitative laboratory results of nitrate concentration changes, the effects of these factors on each other and the mathematical relationships between the variables were tested with the Pearson correlation and linear regression method. Findings: The results show that during the investigated period, agricultural land has increased and barren land has decreased. The consumption of chemical fertilizers has also increased. The level of nitrate concentration of underground water sources shows that during the period under review, the concentration of nitrate in underground water wells has increased. The analysis of the correlation coefficient also showed that at the error level of 1% (99% confidence level) there is a significant relationship between the concentration of nitrates in underground water with the area of agricultural land and the amount of fertilizer used. This means that as the area of agricultural use and the amount of chemical fertilizers increase, the concentration of nitrates in underground water resources also increases. In the presented regression model, the accepted square value (R2) is equal to 0.993 and it indicates a relatively strong relationship between the dependent variable (water nitrate concentration in underground water sources) and the independent variables (agricultural area and the amount of chemical fertilizer used). Discussion and Conclusion: The results indicate that with the increase in the area of agricultural land, the consumption of chemical fertilizers has increased in the research area, and due to the nitrate leaching process from the soil surface, the nitrate concentration in underground water sources has increased, which is one of the important reasons for the increase in nitrate concentration in the study wells.

An overwhelming problem of modern life in large and industrial cities can be considered as air pollution. In order to reduce the air pollution harmful consequences, it necessitates finding out crucial air pollution parameters and their lateral effects. In this study, meteorological and air pollution data in Tehran were investigated; afterwards the changes in annual mean and correlation of these parameters and their linear model environmental pollutants were determined based on the meteorological parameters. Meteorological parameters, the important parameters in specifying the air pollution, have been scrutinized in this study. Tehran Air Quality Index pollutants variables (NO2, SO2, O3, CO, PM-10) and meteorological elements can be named as if temperature, relative humidity and wind speed. Meteorological and pollutant data were obtained from, synoptic and department of environment study stations. There of the average annual change of these parameters, correlation and linear model of environmental pollutants based on meteorological parameters has been acquired via statistical software. The results, estimated from 60 equations, illustrated that only through 40 equations the relations between pollutants and meteorological parameters was observed in which the differences in number of sample, type of relation and degree of correlation existed. The best equation with more than 49% coefficient of determination for ozone versus temperature was recognized in Azadi station. This correlation for SO2 versus wind speed with more than 24.9% coefficient of determination was calculated in Vila station. Pardisan station for SO2 versus temperature with more than 32.3% coefficient of determination and Tajrish station for ozone versus temperature coefficient of determination of more than 22.4% were selected as the most outstanding equations. With regard to the fact of the significance of the relation between pollutants and meteorological parameters, it perceived that weather parameters can be effective on the air pollution levels in Tehran.

Nowadays, breast cancer is the most common cancer disease among women. Statistics shows a six percent increase in Iran which indicates it as a serious danger. However, its danger can be prevented increasingly by early diagnosis or prediction. By medical science progress, the way for developing of a system with the capability of prevention, prognosis and cure by using the new technologies is paved. Medical data mining tries to design a model and find relationships among risky factors to predict the condition of future patients with the aid of current data. We try to compare different data mining algorithms and combination of these algorithms to develop a new, efficient method with high accuracy and capability to perform on local data. Finally, proposed method which improves efficiency of Naive Bayes with Adaboost algorithm can predict the kind of benign or malign tumor with the 96/67% accuracies. Required data for this procedure is extracted from UCI site to diagnose the kind of tumor with 569 records and 32 variables. Manuscript profile

Conodonts are the most important fossil remains from the largest Phanerozoic extinction as well as the mass extinction of the late Paleozoic and could be used for exact dating during this period. Triassic deposits located in the Elikah Formation contain exposures in most of the Alborz sections as well as the Zal section in northwestern Iran. In this study, the Elikah Formation was investigated from a biostratigraphy point of view in the type section and Ruteh section of the Alborz Mountains and Zal section in the Jolfa region based on the existing conodonts. Biostratigraphy study of more than 300 samples taken from these three sections, resulted in the identification and introduction of the following conodont biozones: Taxone Range Zone Hindeodus parvus and Pachycladina symmetrica – Pachycladina Oblique Assemblage Zone in the type section, Hindeodus parvus Taxon Range Zone, Hadrodontina –Pachycladina Assemblage Zone and Parachirognathus – Furnishius Assemblage Zone in the Ruteh section and finally Hindeodus parvus Taxon Range Zone, Isracicella staeschei Taxon Range Zone and Arachirognathus – Furnishius Assemblage Zone in the Zal section. These biozones indicate that the Elikah Formation, in the three previously defined sections, is Early Triassic (Griesbachian). Additionally, comparison of the biozones in these sections illustrates a biostratigraphic correlation of Early Triassic deposits in the Zal, Ruteh and type sections. Manuscript profile

Tomatoes have many varieties that differ in traits of plant growth, quality and shape of the fruit and other traits. In order to investigate the morphological variation of some tomato cultivars in Khash region, an experiment was conducted as a randomized complete block design with three replications and ten cultivars including Orabana, Red Claude, Red Top, Red Jerez, Western Red, Sunsild, Rio Grande, Delba F1, Tivi F1 and blankets Pride. At the end of the experiment traits such as number of fruits per plant, average fruit weight, fruit diameter, final yield, biomass, harvest index, fruit juice volume, fruit dry weight, total soluble solids, acidity and vitamin C were evaluated as agronomic traits. Were affected. At the end of the experiment, after multiple analyzes, it was found that Tivi F1 and Delba F1 hybrids and Orabana had the highest yield and were suitable for cultivation in Khash region. Also, cluster analysis showed that among the 10 varieties of 3 varieties in group A, 5 varieties in group B and 2 in group C were placed. This grouping showed that genetic diversity followed a significant pattern, because cultivars with better and more closely related conditions under conditions were similar in the same groups. Based on stepwise regression results, the number of fruits per plant justified 63.09% of the fruit yield per plant changes. After fruit number per plant, average fruit weight and number of days to flowering had the greatest effect on fruit yield per plant. Manuscript profile

Robat sefid region located in mashhad to torbat road and surrounded with ophiolite outcrop serpentine formation that could be mentioned as source of Lithogenic contamination.   Considering importance of this matter, in this paper heavy metal studying and evaluation have been done in soil sources of robat sefid region. So heavy metal density in 11 soil samples have been studied and interoperated. For this aim multivariate statistical methods and index of geoaccumulation, enrichment factor, contamination factor and modified degree of contamination have been used. Correlations between elements have been evaluated with multivariate statistical methods (Pearson Correlation, Cluster Analysis and principle component analysis). Based on evaluations, ophiolite rocks (Serpentine، Gabbro، Dunite and Harzburgite) has been considered as Lithogenic source of elements in region. Based on index of geoaccumulation measurement for soil, Nicole has the highest rate of contamination in this region. Enrichment factor calculation shows that Nicole and Chromo have very high contamination and Cobalt has high contamination in this region. Also contamination factor measurement shows severe enrichment of Nicole in this region but region geology structures and ophiolite rocks weathering are the entrance source of these heavy metals and have Lithogenic source.

The urban thermal island phenomenon has intensified in recent years, due to the changes in urban airspace along with the rise of urbanization. Spatial-temporal patterns of biophysical constituents, which include vegetation, impermeable surfaces and soil type in the city, have a significant impact on urban thermal islands. The purpose of this study is to investigate the role of effective urban parameters in the formation and clustering of Yazd urban thermal islands. In order to achieve the proposed goal, the thermal map was developed using the single-window algorithm on the thermal band of OLT sensor of Landsat ETM+ sensors for August, 2015 and 2017; Land surface temperature (LST) was calculated and using spatial correlation (LISA), hot and cold clusters of thermal islands of Yazd were extracted. In order to evaluate the surface temperature, with the intensity of LST, spatial heterogeneity of the clusters increases nonlinearly. The relationship between the thermal islands with NDVI and urban carrion layers were investigated: cold clusters are around the places with more green space and hot clusters are in the arid areas and in areas without vegetation cover. The result of the correlation between the surface temperature and the NDVI, NDBI, and NDBaI indicated that the relationship between NDVI and LST is negative, and the relationship between NDBaI and LST is also nonlinear and negative. But the relationship between NDBI and LST is nonlinear and positive. A spatial correlation with the local index has emphasized on the extent of thermal islands in the studied periods.

Punica granatum L. (pomegranate), is among important horticultural plants which is cultivated in many parts of the world and appreciated for its fruit value and medicinal properties. Several pomegranate cultivars are cultivated in Iran which differs in fruit characteristics and agronomical features. In spite of economic importance of pomegranate cultivars, limited knowledge is available on genetic and cytogenetic peculiarities of these cultivars. Therefore, we aimed to investigate cytogenetically twelve unreported cultivars and also compile all available data on chromosome pairing, chiasma frequency and meiotic irregularities in 88 cultivars and carry on a meta analysis. We found all cultivars to have 2n = 2x = 16 chromosome number, but significantly differed in all meiotic features studied. Most of meiotic features studied were significantly correlated while PCA analysis revealed that characters like chiasma frequency and distribution as well as ring bivalents are associated to each other and differentiated the cultivars which were distributed towards longitude. Similarly, characters related to meiotic irregularities such as chromosome stickiness and anaphase failure differentiated the cultivars which were distributed toward altitude. PCA plot placed pomegranate cultivars in three major groups due to meiotic difference. Data obtained can be used in future conservation and breeding of pomegranate. Manuscript profile

To calculate correlation coefficients and path analysis of some traits related to grain yield, 15 genotypes of safflower were studied under non-stress and drought stress conditions at two different sites (with 10 meter distance) in the field of College of Agriculture of Lorestan University, Iran. Each experiment was conducted in a randomized complete block design with three replications. Analysis of variance showed that there were significant differences among the genotypes for all measured traits and yield in both stress and non- stress conditions. By using stepwise regression, best model was estimated for the two conditions. Sequential path analysis of the correlation between grain yield and other traits showed that days to start flowering, 1000-seed weight and stem diameter had direct effects on grain yield under non-stress conditions, while under drought conditions, seed weight per plant and 1000-seed weight had direct and positive effects on grain yield. Thus, to obtain high yielding varieties of safflower under drought stress condition, we showed attempt to select varieties with high seed weight per plant. Manuscript profile

In order to identify traits affecting sugar yield and determine cause and effect relationships between them, 13 different domestic and foreign sugar beet monogerm cultivars were evaluated at three different harvest time (7 October, 22 October, and 6 November) in a RCB design with four replications in terms of 11 important quantitative and qualitative traits in 2018 crop season in Miandoab Agricultural Research Station. The ANOVA results showed that the difference between studied cultivars was significant for all evaluated traits at 0.01 probability level. Phenotypic and genotypic coefficients of variation were high for most traits, indicating relatively high variability in the studied cultivars for evaluated traits. Genetic correlation coefficients between traits showed that the highest positive and significant correlations were observed between sugar yield trait on the one hand and white sugar yield (0.88**), impure sugar content (0.71**) and white sugar content (0.65**) traits in that order, and the highest negative and significant correlation was found between sugar yield trait on the one hand and molasses sugar (-0.62**), alkalinity coefficient (-0.58**), and root potassium (-0.52**) traits, in that order. In multiple regression analysis by stepwise method, sugar content, white sugar content, α-amino nitrogen, and root yield traits were entered into the regression model, respectively, that explained %84 of the total sugar yield variations. Based on path analysis results, sugar content (1.12) and root yield (1.03) traits had the highest positive direct effect on sugar yield and thus, selection based on these traits can help us to achieve high-yielding genotypes.

Risk level evaluation of power systems and reduction of its related destructive effects costs have been transformed to one of the basic challenges in power industry’s operation and scheduling. In this paper a new method for mathematical modeling of failure correlation of parallel transformers using Poisson process and multi-Gaussian Copula function is presented. In this method, by using computation of selected reliability indices and related costs, a modeling method for estimation of expectation value of failure cost of parallel transformers with failure correlation and also cost of annual risk of power system has been proposed. According to the capability of production of stage-gate process of the system real mode and failure correlation and probability of parallel transformers, sequential Monte Carlo method for calculation of system’s reliability indices and related costs estimation has been employed. Simulation results of the proposed method show that annual increase of failure correlation probability of parallel transformers in power stations, will lead to increase of expectation value of their failure, level and cost of power system’s risk.

This study was conducted for evaluation different reference evapotranspiration models in Islamabad-Gharb area. for this purpose, the monthly data of Islamabad-Gharb synoptic Meteorology stations during a period of 30-year (1394-1364)were used. After restruction of the missed data and verification of the reference stations, values of the evapotranspiration were calculated with 9 valied formulas using REF-ET software. In order to determine the best method, the output values of the models were compared with evaporation pan data, using some statistical criterio. According to the results, the highest correlation coeficient (r=0.99) was obtained between the output data of the Blaney- Cradle model and evaporation pan. Also the minimum root mean square error (RMSE) values of 22.2 (mm/day) and 24.42 (mm/day) were belogend to the models of torque and Blaney- Cradle, respectively. Furthermore the highest efficiency (EF) value(0.93) was obtained for the both models of Blaney- Cradle and torque. Hence by considering the resulted minimum mean percentage error (MAPE) value (0.01) for Blaney-Cradle, this model was proposed as the most suitable model for application in the studied area.

Pollution of the air is amongst the most vital and complex issues in industrial civilization which has a menacing influence on the environment. Furthermore, climatic over-measurement has increased the spread of these pollutants in the atmosphere, which will consequently augment their influence on human beings and their natural ecological systems. The aim of the present study is analyzing the relationship between climatic elements and air pollution with the deaths caused by heart diseases in Tehran from 2006 to 2010. In this regard, the relationship between climatic variables and pollutant variables with death caused by heart diseases was scrutinized using mixed methods of Pearson product-moment correlation and multiple regression .The findings demonstrate that there exists a negative correlation between climatic elements of the temperature with a correlation coefficient of. /47. The pressure with a coefficient correlation of ./42 has a direct influence on the rate of the deaths from heart diseases with the meaningful significance of ./99. All the elements show a significantly meaningful correlation with the deaths from heart conditions ; notwithstanding, the most meaningful correlation was observed in carbon monoxide which was. /41 with a meaningful significance of. /99. When all the chemical elements in the air are present en masse, a unit of change in temperature based upon the Celsius degree will have a decrease of 17/12 in death caused by heart conditions. A unit of one percent change in humidity leads to a decrease of 7/9 percent in deaths. The change of one unit of PPM in carbon monoxide causes an increase of 26/2 and one unit of change in suspended particles based upon micro gram or cubic meter causes an increase of 1/4  in the rate of the deaths caused by heart diseases in the city of Tehran.

As the urban development has overtaken the capacity and potentials of the governments and municipalities in extending the infrastructures and providing employment, informal settlements are quickly and irregularly increasing. Studies performed on the informal settlements in Sanandaj (Kurdistan province) suggest that the majority of immigrations to the suburban areas of Sanandaj are from rural areas and are resulted from economical and security concerns (during the imposed war of Iraq against Iran and insecurities within the province). Studies on comprehensive and detailed plans of Sanandaj show that no better position has been considered for the low-income urban classes. In other words, they are missed in the studies. Also the demands of these classes for housing and the way these demands are supposed to be fulfilled have not been studied in the urban development plans. Therefore, one of the reasons that drive these low-income classes to the suburban areas of the cities and their settlement outside the area is attributed to the lack of attention to the demand for housing of these classes in developing formal plans. In addition to determining the most important structural problems in the informal settlements of Sanandaj, using correlation matrix, the rate of correlation between indices has been studied in this paper and the results suggest that the first important problem in suburban areas of Sanandaj is the usage of high amounts of low quality and inordinate materials in the construction of the buildings. The second important problem is low average area of residential parcels. Finally in this paper, the informal housing area of Sanandaj is assessed, using SWOT technique. Manuscript profile

The experiment was laid out in complete block design with three replications. Seeding ages with three levels (20, 30 and 40 days) were considered as main plots and plant densities with four levels (13, 17, 22 and 33 plants/m2) were allocated as sub plots. Analysis of variance showed that the effect of seedling age on number of tillers per plant, numbers of grains per panicle and grain yield was significant. The plant density had significant effect on all traits (expect, 1000grains weight). Interaction of two factors had no significant effect on any of the traits. The means comparison showed that the highest of number grains per panicle and grain yield were obtained for 30 days seedling age. Also, the highest of number of tiller per plant, number of fertile tiller per plant, number of grains per panicle and percent of unfilled grain were obtained by 13 plants per m2. But the highest biological yield, harvest index (HI) and grain yield obtained by 33 plants per m2. Based on simple correlation coefficient of traits, grain yield had significant positive correlation with biological yield, number fertile tiller per plant and number grains per panicle.

Basil is one of the important plants belonging to the mint family, which is used as a medicinal plant, spice, and also as a fresh vegetable. In order to study the relationship between leaf yield and agricultural traits, 22 basil genotypes were evaluated on the basis of split plot design based on randomized complete block design with three replications in pots under field conditions. The main plot included drought stress in three levels (normal, moderate and severe stress) and the subplot included genotype (22 levels) and agricultural traits were measured. Correlation of traits in all three conditions showed that leaf yield had a positive and significant correlation with the traits of stem fresh weight, number of leaves, length and width of leaves. Considering the leaf yield as a dependent variable and performing a stepwise regression analysis in normal conditions (stem wet weight, number of leaves and leaf width in the first stage, respectively), moderate drought stress conditions (stem dry weight in the first stage) ) and severe drought stress conditions (stem wet weight in the first stage) were entered into the model and the model was significant at the level of 1%. Path analysis showed that stem wet weight in normal conditions, stem dry weight in moderate stress condition and stem wet weight in severe stress condition had the highest direct and positive effect on leaf yield. Therefore, the most important traits as a selection index for improving leaf yield werestem fresh weight, leaf number, leaf length and width, respectively. Manuscript profile

The purpose of this paper was to assess the overall risk in various financial sectors, including banking, insurance and investment companies. Pervasive risk in general indicates the possibility of collapse of the entire financial system in a crisis. While in most cases, investors in different markets worry about losing the value of a stock or commodity and measure the risks involved, the risk is pervasive, focused on the market as a whole and likely to fall. In this study, the method of measuring changes in value at risk based on the returns of financial institutions has been used. In this study, statistical information of banks, investment companies and commercial insurances during the years 1380-1399 has been used. The results show that all three sectors during this time period are significantly involved in hedging risk in Iran and investment companies have the largest share in hedging risk, followed by segments respectively. Banking and insurance are included. Manuscript profile

Modeling synchronous time series in financial systems is very complex. In order to analyze such series, we require procedures that can determine long-term relations with high accuracy. Multifractal detrended cross correlation analysis (MFDCCA) is a technique to analyze long-term relations through detrending the time series. In this work we propose a novel technique for a more accurate detrending of a financial time series, called indicator-based multifractal detrended cross-correlation analysis (IMFDCCA).We aim at using financial market technical analysis indicators to better determine correlations between financial time series.We investigated our method on currency pairs EUR/USD and USD/JPY and their long-term and short-term relations of these series were determined as multifractal.In order to evaluate the effectiveness of IMFDCCA, we used R.S and GHE techniques for the Hurst exponent estimation. The evaluation results on a collection of 8 years data (2011-2019) show that the proposed method compared to the baseline (MFDCCA) reduces the RMSE by 30% and 26% using R.S and GHE respectively.

The Banking Crisis is previous decades caused the discussion of Systemic Risk in the financial market, including the Banks, has been taken into Consideration by Policy- makers. Based on this in this research using Delta Conditional Value at Risk (CoVaR), the Systemic risk in Iran Banking Section has been evaluated. For this reason, seventeen banks out of all ones which have been listed in Tehran Stock Exchange and the equity of their Owners from 1389 to 1395 was available, have been chosen. The results Show that CoVaR for Khavarmianeh Bank Was the most (15.61) and for Sarmayeh Bank was the least (0.32). These results indicate that the crisis or disturbance in Khavarmianeh Bank more than the other Banks, affects the Financial System and Sarmayeh Bank has the least effect. In other words, any crisis in khavarmianeh Bank will give a rise of about 15.61 Percent to the Financial System risk, while the corresponded value for the Sarmayeh Bank is only 0.32 percent.

In this paper, I present an approach for valuing credit default swap (CDS), tranches of synthetic collateralized debt obligations and kth to default swaps. One-factor gaussian copula model is utilized to model default correlation for each pair of companies. In this research, I analyze the effect of different hazard rates and different default correlation between each pair of names on the spread to buy protection for multi-name credit products. The findings in the valuation of a tranche of a CDO show that if the correlation is low, the junior equity tranche is very risky and the senior tranches are very safe. As the default correlation increases, the junior tranches become less risky and the senior tranches become more risky. The valuation of kth to default swaps also shows that as the hazard rate increases, the spread of all swaps increases. Also, increasing the correlations between all firms while holding the hazard rate constant lowers the cost of protection in kth to default CDS if k is small and increases it if k is large.

AbstractOne purpose of accrual accounting is to mitigate the timing and matching problems inherent in cash flows. Cash flows have timing and matching properties that impair their ability to measure performance. Net cash receipts and payments can occur in periods that differ from the economic event (the timing or spreading problem), and cash inflows and outflows from a given economic event might occur in different periods (the matching problem). The economic role of accruals is to mitigate these timing and matching issues. These problems cause temporary fluctuations in cash flows. Accruals smooth temporary timing fluctuations in operating cash flows and thus it is expected to find a negative correlation between accruals and changes in cash flows. It is also expected that the negative correlation between accruals and cash-flow changes grows as cash flow problems intensify because accruals will increasingly counteract cash flow changes as a firm’s cash flows increasingly stray from desired properties. According to Dechow et al. (1998), the negative serial correlation in cash flow changes shows the cash flow timing and matching problem. The timing and matching problems of cash flows counteract each other. The timing problem leads to a positive serial correlation in cash flow changes. While the matching problem leads to a negative serial correlation in cash flow changes. According to Dechow et al. (1998) model,  the serial correlation in cash flow changes is a function of operating cash cycle and profit margin and the magnitude of negative serial correlation in cash flow changes depends on the relative magnitude of the operating cash cycle and the profit margin.  The longer the operating cash cycle and the smaller the profit margin, the negative serial correlation in cash flow changes is more severe. So it is expected that the negative correlation between accruals and cash-flow changes grow as the negative serial correlation in cash flow changes is severe (longer operating cash cycle and smaller profit margin). This study investigates the extent to which accruals are reconciled whit their ultimate purpose in mitigating timing and matching problems inherent in cash flows. A sample of 153 firms listed in the Tehran Stock Exchange (TSE),,is analyzed using panel data regression models. we observed that there is a negative correlation between accruals and cash-flow changes and this negative correlation increases as the timing and matching problems of cash flows become more severe. The results of this study show that accruals are used to mitigate timing and matching problems of cash flow and firms listed in the Tehran Stock Exchange use accruals more when there are more problems with cash flows.

In order to investigate the path analysis of effective traits on durum wheat yield, an experiment was conducted based on randomized complete block design with 18 genotypes and four replications in Agricultural and Natural Resources Research Center of Lorestan province during 2014–2015. In Factor analysis, the first factor was named as influencing factor on flag leaf characteristics, the second factor was named as influencing factor on height, and the third factor was named as influencing factors on yield performance. According to results of genetic correlations, biomass yield, straw yield, kernel per spike and spike length had very strong positive correlation with grain yield. According to results of stepwise regression and path analysis, straw yield, kernel per spike and peduncle length entered to the regression model, and so the straw yield had highest and largest direct effect on grain yield. As kernel per spike and straw yield were more important, these traits could be advisable in breeding programs of durum wheat. In present research, bi-plot analysis was used to simultaneous study of traits and discrimination of genotypes related to these traits, and hence, genotypes of Dehdasht, Seimareh, Pod-20 and Alas were introduced as hopefull genotypes for future breeding programs.

Drought stress is the most limiting factor for producing wheat grain yield, especially in southern Iran. In order to recognize the most influential appropriate agronomic traits on grain yield of promising wheat genotypes (16 line) under normal irrigation and drought stress conditions, this study was conducted at Darab, Fars province in 2012-2013 and 2013-2014. Drought stress was started after anthesis and continued to physiological maturity. Days to physiological maturity was counted during growing seasons. At the end of growing seasons, 1000-kernal weight, grain no. per spike, spikelet no. per spike, floret no. per spikelet, tiller no. per unit area, crop height, grain yield, above ground biological yield (BY) and harvest index (HI) were measured. Four statistical methods including simple correlation, multiple linear regression, stepwise regression and path analysis were used for determined the relationship between the above mentioned traits and grain yield under the two irrigation treatments. Results showed that BY and HI for normal irrigation and for drought condition days to physiological maturity, BY and HI were the most important influential traits on yield. Based on the most statistical analysis, the BY role on grain yield was lower at drought condition than normal irrigation. Also, improving grain yield was attributed to HI under drought condition.

The purpose of this research was to analyze the effect of monetary policy on gross domestic product and inflation via house price index as a proxy for other assets in Iran in 1989-2008. For the analysis time series data and vector error correlation method were used. The results showed that in the pattern 1 the positive monetary shocks in the short run increased the product and decreased the prices but, in the long run it decreased the product and increased the prices. The debt shocks of the banks to the central bank in the short run had little effect on the product and the prices. In the intermediate run these shocks had decreased the product and increased the prices. And in the long run it increased the product and decreased the prices. In pattern 2 positive shock of the legal deposits ratio leads to decrease in the production and increase in the inflation in the short, intermediate and the long run, through the banking lending. Results shoed also that money policy instruments (banks loan to the central bank and the rate of legal deposits) had a little effect on the granted facilities of the banks. Manuscript profile

In order to study genetic variation and heritability in fifteen cultivars of red clover in climate conditions of Broujerd an experiment in based on randomized complete block design (RCBD) with three replications under irrigated conditions in Agriculture Researches Center and National Resources of Broujerd in 2013-2014 cropping year was carried out. The measured traits were including of dry and wet forage yield in three cuts, plant height, digestibility percentage, crude protein percentage (%CP),Water soluble carbohydrates (%WSC), insoluble fiber in acid percentage, crude fiber percentage (%CF) and ash percentage (%AH) in two cuts and ratio leaf to stem and regrowth rate in one cut. The qualitative traits were measured by near infrared reflectance (NIR) technology. The results of analysis of variance were indicated that differences between cuts for all traits and genotype effect and interaction genotype × cut for all traits except plant height and ash percentage were significant. Compare means, Duncan method were showed Chamran, Renova, Shahrecord and Reszti cultivars with range between 52 to 56 t.ha-1 wet forage and range of 17.3 to 18.3 t.ha-1 dry forage in general three cuts had the highest forage yield. In among them Renova and Shahrechord cultivars had the highest plant height and ratio leaf to stem, but Charmahal had high mean for qualitative traits including digestibility and total ash and low mean for ADF and %CP. low In other words, it had higher forage yield and quality. In comparison between means of cuts, the highest and lowest forage yield related to 1 and 3 cuts, respectively. Simple coefficients of correlation among forage yield with plant height and digestibility was positive and with ratio leaf to stem and soluble carbohydrates in water was negative and significant. Coefficients of correlation between digestibility and protein percentage were positive and significant and these traits had negative and significant correlation with soluble carbohydrates in water, percentage crude fiber and ADF. Results of principal components analysis (PCA) for 15 genotypes in 11 traits showed three first principal components explained 72% from total variation. In the first component, wet forage yield, digestibility percentage, crude protein percentage and soluble carbohydrate in water explained the highest variation. In the second component, plant height, insoluble fiber in acid, crude fiber percentage, total ash percentage had the highest vector coefficients. In the third component, dry forage yield with ratio leaf to stem had negative correlation. In cluster analysis base on the ward's method 15 genotypes of red clover for 11 traits placed in three clusters. Shahrod and Renova Cultivars placed in cluster number 3, and had high forage yield and medium digestibility percentage, crude protein percentage and soluble carbohydrates in water. In contrast, cultivars placed in cluster number 2, had medium yield but better quality. Cultivars placed in cluster number 1 had lower values for quantitative and qualitative traits.

In order to investigate relationship between yield and its components in bread wheat, tested during 2011-2012 were conducted in Agricultural Research Station of Gonbadin randomized complete block design with three replications whit 10 bread wheat genotype (Morvarid, N-87-4, N-87-9, N-86-6, N-86-8, N-80-19, N-86-5, N-85-5, Kohdasht, Line 17). In this experiment, were measured 7 morphological traits. Analysis of variance genotypes for all traits was significant at 1% probability level. N-85-5 and Line 17 genotypes produced the highest and the lowest grain yield, respectively. Among all tested traits, the number of fertile spike had the highest correlation (0.999 **) with grain yield. Using stepwise regression, the number of fertile spikes entered the model as an effective attribute, justifying 99.8 percent of the data variation. In order to find the causal relationships, the path analysis was performed for grain yield The direct effect on the grain yield was related to the number of fertile spike traits. The results of cluster analysis by ward method showed that the studied cultivars were classified in two groups and the second group in terms of grain yield was the most (397.66). According to the results, can be said that N-85-5 genotype had the highest grain yield and trait number of fertile spike was identified as an effective trait for increasing grain yield.
