the present study aimed at developing an integrated decision-making model based on remote sensing (RS) and GIS to identify the geomorphotourism potentials of Tajnood Valley and Hemmatbad Desert in Zirkuh County.

In the present study, after identifying landforms, geomorphological features, and geosites through RS, the Fassoulas, GAM, and Comanescu models were employed to prioritize and value geotourism potentials, including geosites, geomorphosites, and economic and cultural sites. Finally, in order to overcome the challenges of each model and take advantage of the capacity of all models, the Fassoulas-GAM-Comanescu integrated model (FA-CO-GM) was used based on the Analytical Hierarchy Method (AHP). In this way, it is possible to combine several factors that are considered separately in each model and to use the advantages of all models.

The final map of the decision-making model based on RS and GIS integrated from Comanescu, Fassoulas, and GAM shows that 36% of the region is located in a high potential zone, corresponding to the geomorphological landforms, proper access, extended perspective, and high viewpoints. 51% of the region is located in a very high potential zone due to its representativeness, geomorphological diversity, rarity, intactness, and integrity in geosites. In order to verify the accuracy of Comanescu, Fascilos, GAM and AHP models, a sample t-test was used. The significance level of the test is less than 0.05 and it is within the standard and significant test limit.

While identifying and evaluating the capability of the geomorphosite of Tajnood Valley and Hemmatabad Desert in the dry region of Zirkuh county, it was found that after applying several valuation models, with one of the multi-criteria decision-making methods (MCDM) in GIS, it is possible to fix these defects and prepare a suitable zoning map for the geosite and combine the results of several models.

Company law in the era of covid-19 with critical evaluation method based on Multi Grounded Theory.

Border towns have certain characteristics such as the geographic isolation, remoteness from industrial and economic poles, governance of traditional culture, lack of economic, political and cultural development, as well as the lack of sustainable security. However, despite having all of these features, these areas are considered as the most sensitive and strategic parts of the country. One of the most well-known methods of developing these areas is the establishment of border markets that can create a fundamental transformation in production and employment; population consolidation, income growth, smuggling prevention, and security development are also among the advantages of creating a border market. The aim of this purpose is to investigate the role being played by Yazdan border market in ensuring the economic security of Haji Abad city. To examine the positive effects of establishing this market, we took satellite imagery in 1989, 2001, 2006, and also used Google Earth map of the development process of Haji Abad border market by utilizing GIS. SPSS analyses were also used to find the effects of the establishment of this market on the economic security and development of Haji Abad city.

Nowadays, physical development of the cities is one of the key issues in the cities of developing countries, especially Iran. This is increasingly important in border cities due to the remoteness of border cities from central cities, as prohibition of the migration of people. One of the important aspects of the physical development of these cities is the creation of economic capacity in the city where due to their potentials and capabilities can be done. Accordingly, the development of economic activity and the construction of border market as an important stimulus play a significant role in the physical development of these cities. In this study, in order to evaluate the impact of Yazdan border market on the physical development of Hajiabad city , field studies, observations, interviews and TM and ETM satellite images in 1989, 2001, 2006 and Google Earth image in 2013 have been used. The physical development trend maps of this city prepared by using ENVI and ArcGIS softwares with regard to residential texture by image processing and visual interpretation and then, the market efficacy on the physical development of this city at two viewpoints, responsible persons and experts and tradespeople using one-sample t-test and Chi-square analysis at the SPSS software have been analyzed respectively. The results of one-sample t-test and Chi-square showed that establishment of this border market had a positive effect on the physical development of this city, at 95 and 99 certainty percent, respectively. Also, the maps of development trend of the city showed the more development beside the road and to the East of the city; toward Yazdan border market, higher than another directions. So, the problems of border area by more investing in these area such as Hajiabad city can be solved. Meanwhile, economic improvement of Yazdan border market can help the physical development of this city and prevent the migration to other central cities.

The study was conducted to investigate the effect of humic acid on germination properties of medicinal plants Borago officinalis and Cichorium intybus in a completely randomized design with five replications.

Pot experiment was carried out to investigate the effects of ethylenediaminetetraacetic acid (EDTA) on some morphological characteristics of Thlaspi caerulescens L., and also on the accumulation of lead (Pb) and zinc (Zn) in roots and shoots of T. caerulescens L.. Experiments were then set up in three treated pots with doses of 3, 6 and 9 mmol kg-1 of EDTA and control pots (C: uncontaminated soil and W: contaminated soil). The results indicated the significant effect of EDTA on morphological characteristics and accumulation of heavy metals in the plant (P

The water requirement of plants for the purposes of water resources management, water program planning, irrigation water use efficiency and to achieve the maximum yield is essential. Indiscriminate use of water and drought phenomenon in the recent years caused a serious problem for water resources management. Therefore, to determine the Nigella sativa L. water requirement a study was conducted in college of agriculture Research Farm in RaziUniversity in the city of Kermanshah during two years (2009-2010 and 2010-2011). During the investigation, the irrigation was determined by using of data logger equipment of IDRG SMS-T1. During the experiments, the soil humidity was determined in field capacity condition. The evapotranspiration was calculated using water balance equation. Finally, the Nigella sativa L. water requirement was detremined as 702.12 and 746.11mm for years 2009-2010 and 2010-2011 and average water requirement was determined as 724.11mm respectively.

Coriandrum sativum L. is one of the most important plants compared to the other herbs and medicinal plants as a planted covered area in Kermanshah province. For a suitable irrigation management programming, the awareness of crop coefficient and water requirement in different plant stages is essential. The ratio of actual evapotranspiration to reference crop evapotranspiration is defined as crop coefficient. A study was conducted to determine the crop coefficients of (Coriandrum sativum L.) in Faculty of Agriculture Research Farm in Razi University in Kermanshah city during 2009-10 and 2010-11. For this purpose, three water balance drainable lysimeters with diameter of 1.20 m and a height of 1.40 m were used. In this regard, to calculate potential evapotranspiration, the Penman Monteith equation for potential evapotranspiration and water balance equation to measure actual evapotranspiration were used. Finally, the values of crop coefficients for different (Coriandrum sativum L.) initial, development, middle and end stages were determined as 0.66, 1.19, 1.36 and 0.98, respectively.
