This research has examined the effect of applying limitation on the price of stock representing indices of investment market behavior. The index of applying limitation on the price of stock is stock price limit which is considered as an independent variable and introduces indices of investment behavior including trade volume, the days needed to do business and trade, the number of stocks equal base volume and the trend to buy. These factors are determined as 3 variables for the research. This paper examined Tehran Stock Exchange from 2003 to 2008 to collect Data and information related to stock price periodically and then by considering the effect of the independent variable on dependent variables, the averages were compared. It’s important to note that, except stock price limit, there are other factors which have effect on dependent variables. We didn’t consider those factors here. After gathering data from different sites Tehran Stock Exchange and comparing them, one by one, with other data base and using data of Brokers, studying the characteristics of companies that statistical society chose them as a sample and examining the data in term of 3 hypothesis, there wasn’t any relationship between stock price limit and 3 dependent variables in Tehran Stock Exchange according to the research sample and the method used.

The spatial identity plan, and the effects that this component has on the analysis of the distribution pattern of natural and human phenomena, and their arrangement, have opened new horizons in the knowledge of geomorphology. In this article relying on drawing techniques, we examine the spatial identity of Lake Ovan in relation to mass movements of materials at a specific level and scale. For this purpose, we reveal the current state of domain movements with the help of offset tracking technique in the images of Sentinel 1 (2014- 2022) with the help of Snap software. Due to the fact that the detection of displacements is done in small parts of the images, we transferred their location data to Excel software to mosaic and surface reveal them together with the data of other parts of the basin in GIS software. According to the amount of changes calculated in the desired time series and their generalization to the topography of the region in the long time, the spatial identity of Ovan Lake was analyzed. Investigation and comparing the amount of total displacement indicates that the ascending images have reflected the total amount of displacements of the Ovan basin less than the descending images (44-7.5 mm), and usually the maximum displacements have been inclined to the upstream of the basin. The maximum displacements in the descending images varied between 1520 and 8.6 mm per year. Field observations confirm the maximum displacement reflected in the descending images.

This study investigated the effect of extreme precipitation values on the trend of vegetation cover change in southeastern Iran. Extreme precipitation indices were selected using a fixed approach recommended by the Expert Team on Climate Change Detection and Indices, according to local needs and theclimatic characteristics of the study area. These indices were extracted using daily precipitation data from the stations of the study area over a 21 years from 2000 to 2020 utilizing RclimDex software. The NDVI index of MODIS satellite images was used to analyze the trend of annual vegetation cover changes. Also, the multilayer perceptron neural network method was used to examine the relationship between changes in extreme precipitation indices and vegetation cover changes. The results showed that the NDVI index has an increasing trend spatially from the east to the west of the region. Areas with low NDVI were observed in the eastern, southern, and northern parts and areas with high NDVI were observed in the western part of the study area. The trend of NDVI index changes was significant and upward only at Rudan station (P-value = 0.01) and Kahnuj station (P-value = 0.0001). The overall trend indicated an increase in precipitation extremes during the study period. The extreme precipitation indices Rx1, SDII, and PRCPTOT have the most significant on the trend of changes in vegetation cover in the southeastern region of Iran. A comprehensive study of the impact and trend of changes in extreme precipitation indices on vegetation cover in the southeastern region of Iran will lead to the development of sustainable management methods and resilience to climate change.

Diabetes is one of the main metabolic diseases. It is recognized as one of the most complex disorders. Almost, the whole body is affected by diabetes, and metabolism changes sharply in diabetes. Recent research proved changes in insulin and magnesium level in plasma. This study analysed level change in magnesium, lipids and lipoproteins in diabetic rats. Diabetes was induced in laboratory animals whith Alloxan monohydrate injection. It was injected inter peritoneal at 120 mg/kg. 72 hours after injection, the rats were diabetic. At the same time, changes in the lipids, lipoproteins and magnesium level in plasma were assaed. Results of this investigation showed that triacilglycerol, VLDL and LDL in diabetic rats in comparison with controls were significantly increased (p=0). The cholesterol concentration in control groups was 91.51± 21 mg/dl and in diabetic rats was 94.18± 28 mg/dl and therefore was not significantly increased. Plasma HDL and magnesium in diabetic rats were sharply decreased. The findings show an important relation between the increase of glucose in blood and the decrease of magnesium in plasma.

Background: we aimed to find the optimal level of ethanol that can be added such that the radiochemical purity of [18F]FDG is increased and the MFDS and USP stipulated guidelines are met. Materials and Methods: Changes in the radiochemical purity of [18F]FDG were analyzed according to changes in the concentrations of ethanol added. The study used 1 L of 99. 9% pure ethanol. The ethanol concentrations used were 0. 0% (0 μ L) for the control group and 0. 1% (1 μ L), 0. 2% (2 μ L), and 0. 3% (3 μ L) for the experimental groups. Since the radiochemical purity of [18F]FDG may differ according to the radioactive concentrations used, four different radioactive concentrations were prepared: 1580 mCi/16 mL, 3320 mCi/16 mL, 4840 mCi/16 mL, and 6470 mCi/16 mL. Results: The radiochemical purity of [18F]FDG increased significantly when ethanol was added to it at different radioactive concentrations in comparison to when ethanol was not added. When ethanol concentrations of 0. 1%, 0. 2%, and 0. 3% were added, the radiochemical purity increased at all radioactive concentrations (100 mCi/mL, 200 mCi/mL, 300 mCi/mL, and 400 mCi/mL) while meeting the KP and USP standards even after 10 hours following the EOS. Conclusion: It was determined in our study that adding ethanol at the concentration of 0. 1% to [18F]FDG is most suitable as it generates the least residual ethanol while maintaining the radiochemical purity of [18F]FDG at stable levels that meet the KP and USP standards.

Background and Objectives The mitochondrial DNA in blood products can cause physiological changes in cells and patient complications. This study aims to evaluate the effect of storage time on the copy number of free mitochondrial DNA in products of RBCs and leukoreduced red blood cells. Materials and Methods In a cross-sectional descriptive study, 15 units of RBCs and 15 units of leukoreduced red blood cells were evaluated. After determining the hematological parameters and the average blood cell count in each bag, the free mitochondrial DNA copy number was evaluated using the RTPCR method. The mitochondrial DNA copy number was measured in blood products on days 0, 5 and 35. After data collection, Shapiro and Mann-Whitney tests were performed and the analysis was done using REST 2009 software. Results The average hemoglobin level in the blood bags was 17. 6 ±,4. 3 gr/dL. The mean platelet count in packed RBC bags was 132. 02 ±,50. 60, 1000/mm3 of blood. The mean number of red blood cells was 6. 07 ±,0. 14 million per microliter of blood and the mean WBC count in the blood bags was 4. 98 ±,2. 3 per microliter. The number of free mitochondrial DNA copies in the packed RBC product was higher compared to the leukocyte-less RBC products on days 5 and 35. Conclusions The free mitochondrial DNA copy number in RBCs bags was higher than leukoreduced RBCs, and a direct relationship between the amount of WBC and the number of free mtDNA copy number was observed.

In this research, to understand the changes in precipitation daily persistence's share in the supply of Iran's rainy days and precipitation amount, the annual and monthly share of 1, 2 and 3 day persistence' s had been evaluated. These are, respectively, the most significant persistence's of Iran's precipitation. The possible changes in their role are the evidence of climate change of precipitation in Iran. The results of this research are based on Iran's daily rainfall network data in1961- 2004. Evaluation of the trends in the time series, by using linear regression (parametric) and Mann-Kendall and Sen's estimator tests (nonparametric), showed evidences of change in precipitation. The Annual share of 1, 2 and 3 day persistence was in the supply of Iran' s rain days and precipitation respectively decreasing, increasing and increasing. No-trend aria is also increasing. One-day persistence share in the supply of rain days, decreased in May, April and March and 2- day persistence share increased in December. One-day persistence share in the supply of precipitation amount, decreased in May, April and 2-day persistence share increased in December, January and February.

This research aims to investigate the impact of climate change based on the sixth report (CMIP) under two scenarios SSP3_7.0 and SSP5_8.5 on forecasting temperature, wind speed, evaporation-transpiration (ET), and the amount of extractable water (Q) by two CNRM models and ESM was at 16 meteorological stations during the future period of 2025-2044 and 2045-2064. The statistical analysis results showed that the impact of climate change under two scenarios on temperature, ET and Q was significant. CNRM model performed better than ESM in temperature estimation (CC=0.96-0.98). From examining the results of the CNRM model, the maximum and minimum RMSE of temperature in Khormadreh and Zanjan stations were 8.30 and -0.5 , respectively; Also, the RMSE value of wind speed fluctuated between 0.82-0.5 m.s-1. The examination of ESM model showed the fluctuation of RMSE between 2.55-8.45  in temperature parameter and 0.62-0.68 meters per second in wind speed. The maximum and minimum values of Q and ET in the seasonal survey occurred in summer and winter, respectively. Both models had poor performance in predicting wind speed. The maximum ET under the SSP5_8.5 scenario by the CNRM model (first period) at Khorramdare station is equal to 104.29 mm.month-1 and the minimum value by the ESM model (first period) under the SSP3_7.0 scenario at Firuzkoh station is equal to 25.60 mm.month-1 was estimated. The maximum Q under the SSP3_7.0 scenario by the ESM model (first period) at Malair station is equal to 20.70 Lit.day.m-2 and the minimum value by the CNRM model (second period) under the SSP3_7.0 scenario at the Astara station is equal to 0.3 Lit.day.m-2 were estimated.
