Abstract
Comparative and linguistic study of invitations in the cultural context of Iran and Iraq Involvements as linguistic genre are regarded as sociological data and are considered as an indicator of the relationship between social phenomena. By examining invitations of a particular time period, discourses derived from phenomena Social that period. This comparative study, which is based on the analysis of the genre and the critical analysis of discourse, attempts to explore the structure of wedding cards written in Arabic and Persian languages, and the role of social and cultural values. In its formulation. Familiarity with the social approaches of two different cultures, studying the impact of social and cultural factors on invitations, comparing the structure of invitations and explaining the impact of social phenomena on linguistic phenomena are among the most important goals of this research. Since this research examines the social approaches of the two countries and increases the level of recognition of different cultures, it seems necessary to do so. The results of the study show that the importance of the diversity of text and forms of wedding cards in Iran is more significant than in Iraq, with the title acquired in Iraq becoming more and more important, religious and patriarchal categories have a crucial role in the structure of wedding cards in There are two cultures, with the difference that the role of these two categories in the wedding cards of Arab countries is more colorful than Iran.

Abstract
Iran has an arid climate which characterized by long, hot, dry summers and short, cool winters. Therefore, sunlight and its heating effects were important factors of Iranian architecture and gardens structural design. Textures and shapes were selected by architects to harness the light and supply a shadow in the summer.
Water is very important in this climate, both in the architectural design and longevity of gardens. In addition to water, the plants in Iran had been particularly significant. In ancient civilization of Iran, plants have had special position. Supernatural powers that had been in trees such as life-giving, young giving, productivity and Immortality made them sacred for Ancient Iranian people. However, attending to supernatural power of plants was the importance reason that people regarded to plants and made some symbols such as “Life Tree” has income. In Zoroastrian religion books, more values have said about Supernatural cost of plants. Plants have a special value in Zoroastrian Fire Temples, religious ceremony and routine life. Therefore, garden and gardening were sacred for Iranian. The term Zoroastrianism is, in general usage, essentially synonymous with Mazdaism, have discovered dependent on Achaemenids Empire (559–330 BC) and there were in Pasargad. In the Islam tradition the garden as Paradise is, perhaps, even stronger, since the Quran (the central religious text of Islam) describes Heaven as a garden. Islam was spread to the Persians, and reciprocally the Muslims adopted the Persian style of garden. Therefore garden has been invaluable to Iranians. Persian Garden includes some types which one them is Garden City.
Isfahan as the Capital of Safavid Dynasty has designed as a big garden according garden city model. Therefore, some solutions have used in urban design regarding Isfahan's arid climate. Safavid government followed the realization of cities ideal that rooted in Islamic beliefs and opinions. The investigations in historical perspective of Safavid cities indicates the importance of cities as the place for presence of symbols and signs. The Symbols which has remind as the ideological concepts, power of dominating government and also getting identity to the city.
During the history of Safavid urban design, there were some direct and wide streets (Charbagh) which were the main factors of development and improvement of cities among urban functional and symbolic elements. In historical background of Isfahan garden city is pointed to construction of street (Charbagh) which has attracted the European tourists attention and it will investigate in this article.
Initial section of this article is allocated to explain about historical background of Isfahan city in Safavid era and also Charbagh Street. Then this paper with emphasis on some historical documents and analytical studies, compares the Isfahan Charbagh Street with its similar sample in France (Champs-Elysées Street). The conclusion of this article indicates the similarity of Isfahan Charbagh Street and Champs-Elysées Street in some skeletal specifications and the way of formation. French Boulevards were constructed after Isfahan Charbagh in terms of time and they were formed after publishing itineraries and pictures of tourists from this place in Europe .

Abstract
Multiple sclerosis (MS) is one of the most common autoimmune diseases in Iran and the world. To date, many drugs have been developed to control the progression of MS as a chronic inflammatory disease of the central nervous system. Rituximab is a chimeric mouse-human monoclonal antibody that binds to the CD20 receptor on the surface of B cells and induces apoptosis. Today, Numerous studies have confirmed the increasing role of non-coding RNAs in regulating the expression of genes and molecular processes, including apoptosis. Furthermore, bioinformatic analysis results indicate that TUG1 LncRNA is differentially expressed in MS patients. Thus, In the present study the possible role of TUG1 in regulating rituximab mechanism of action and apoptosis induction was experimentally investigated. To do this, specific DNAzyme against TUG1 was designed and transfected into Raji cells in the presence or absence of the drug. After transfection, RNA extraction and cDNA synthesis were performed. Then, the expression of target genes was examined by Real-Time PCR technique. The results showed an increase in CD20 expression and a decrease in SMAD2 expression levels. Furthermore, decreased TUG1 gene expression led to an increase in apoptosis and cell accumulation in the G1 phase. It seems that TUG1 expression level can play a significant role in CD20 expression in B cells and therefore on the therapeutic efficacy of rituximab.

Abstract
In this study, Lactobacillus plantarum bacteria were used for production of blackberry and celery probiotic beverages in two concentrations of 1 and 2% at ambient temperature and refrigerator. The tests included determination of pH, titratable acidity, counting viability of target microorganisms and sensory evaluation. The results showed that with passing time and growth of target bacteria in blackberry and celery beverages, pH was significantly dropped. The results of counting viability showed that among all samples, blackberry beverage containing 2% of the bacteria stored in the refrigerator after 28 days had the highest viability of microorganisms, which is 8.25×107 CFU/ml as well as celery beverage containing 2% of probiotic bacteria stored in the refrigerator after 21 days had the highest viability of microorganisms, 4.02×107 CFU/ml, than the other samples, of which two samples were in these conditions Still called by the name of probiotic beverage. The sensory evaluation also showed that the sensory properties of the BLR1 (Blackberry beverage with 1% bacteria in refrigerator), BLR2 (Blackberry beverage with 2% bacteria in refrigerator) and CLR1 (Celery beverage with 2% bacteria in refrigerator) with their evidence samples also scored without significant difference, but in general, samples of celery beverage scored more than blackberry beverage. From the findings, it can be concluded that blackberry and celery beverages were suitable raw material for growth of Lactobacillus plantarum.

Abstract
In this research, High Order Expansions method implementation in order to obtain an optimal solution for an unmanned aerial vehicle continuous maneuver problem is studied. The main goal of this research, is to describe a specific approach to solve nonlinear optimal control problems using series expansions and algebraic matrix Riccati equation in order to obtain solutions with better performance. Based on this, the state feedback control with different powers is used for optimal commands calculations. Clearly, the control command would be high order and closed-loop; it has been shown it results in a superior performance in smooth nonlinear problems. In this research, in addition to the implementation of High Order Expansions method and its usage, a different approach of dealing with optimal control problem based on this method has been given. Continuous maneuver of an unmanned aerial vehicle problem is solved for investigating the performance of the proposed method. In this example, the High Order Expansions up to and including the third order are used and two different flight scenarios are simulated. By investigating the result of the solution to this problem, the superior performance of the third order optimal command with respect to the first order is illustrated.

Abstract
The life history and predation rate were determined for all stages of female and male of Phytoseiulus persimilis Athias-Henriot fed on the eggs of Tetranychus urticae Koch ˗ as the preferred prey-stage ˗ on rose (cv ‘blarodje’) leaf discs under laboratory conditions at 25±1°C, 75±5% RH, and 16 L: 8 D hour photoperiod. According to the age-stage, two-sex life table model, the intrinsic rate of increase (r), finite rate of increase (λ), net Reproductive rate (R0), Gross Reproductive Rate (GRR), and mean generation Time (T) were 0.296 d-1, 1.345 d-1, 33.48 offspring, 53.87 offspring and 11.83 d, respectively. Moreover, average number of T. urticae eggs consumed by different stages/sexes of P. persimilis was calculated based on the age-stage, two-sex life table model and indicated that the consumption rates increased from nymph to adult in both sexes. Also, our results showed that females consumed prey eggs 11 times more than males. The net predation rate (C0) and transformation rate from prey population to predator offspring (Qp) were 363.54 mite eggs and 10.86, respectively. The results showed that P. persimilis can successfully survive and reproduce on T. urticae eggs on rose.

Abstract
In this research, an innovative approach has been proposed to the calculation of high order sensitivities and designing its guidance commands for an unmanned aerial vehicle landing strategy design. This method, which is called vectorised high order method, has been developed based on high order expansions method and its implementation using matrix-based mathematical calculations. In this research, a method is presented to design and extract the acceleration commands for landing maneuvers, by combining the vectorised high order expansions method and optimal control theory. Accordingly, the sensitivity variables for the given problem are calculated up to the 6th term and then the reference trajectory and acceleration command in the simulations are updated based on the initial deviations. In order to performance evaluation of the proposed method, 3 landing scenarios with the different initial deviations have been considered and the results of simulation of the proposed guidance law have been presented.

Abstract
Prey suppression by predators depends on effective predator: prey release ratios. The effectiveness of Phytoseiulus persimilis Athias-Henriot and Typhlodromus bagdasarjani Wainstein and Arutunjan was evaluated at different predator: prey release ratios for suppression of Tetranychus urticae Koch populations on cucumber plants in the microcosm condition based on three experiments. In the first experiment, 7 days after T. urticae releases, the most reduction in the different stages (densities) of T. urticae and the most increase in both P. persimilis and T. bagdasarjani were observed in predator: prey release ratio of 1:4 followed by ratios of 1:10 and 1:20. In the second experiment, one day after T. urticae release at predator: prey release ratio of 1:4, there was no significant difference between predators effect on the decline of T. urticae stages (densities). In this case, more T. bagdasarjani at all stages was observed on the plants in comparison with P. persimilis. According to the third experiment, 7 days after T. urticae release, there was no significant difference between predator: prey ratio of 1:4 of P. persimilis and 1:2 of T. bagdasarjani on T. urticae suppression. In this case, more P. persimilis was observed on plants in comparison with T. bagdasarjani. Our study demonstrates that the most suppression of T. urticae populations occurred in predator: prey ratio of 1:4 for both predators. Based on our findings, we suggest that P. persimilis and T. bagdasarjani can be released at a ratio of 1:4 for successful control of T. urticae on cucumber.

Abstract
Aim and Introduction
Internal and external economic crises and shocks are inevitable in different countries. Many countries are unable to resist economic crises and witnessed undesirable economic events. On the other hand, some countries are highly resilient to domestic and foreign economic crises. The single-product countries are more vulnerable to economic crises than other countries. Resilience of the economy can help move the economy towards sustainable development.
Sustainable development is a development that meets the current human needs without harming the capabilities of the future generations to meet their needs. For sustainable development, four dimensions including governance, economic, environmental and social dimensions are considered. Analyzing the growth history of countries reveals the fact that international trade has been the engine of economic prosperity and expansion of most advanced and developing societies. In order to achieve sustainable development, it is necessary to have trade relations with other countries of the world.
Also, the country's distance from international trade centers due to specific geographical and political conditions will be an obstacle to the development of the economy. In this way, the peripheral dimension is proposed as the fifth dimension of sustainable development to show the political and geographical isolation of the country. In this article, first, the dimensions of sustainable development and its subgroup variables are determined. Then the impact of sustainable development dimensions on the state of economic vulnerability and resilience of different countries are analyzed. The statistical sample includes two groups of countries including G7 member countries and MENA countries. This study investigates the state of vulnerability and resilience (VR) of these two groups during 2017-2020.
Methodology
In this article, Graph theory and Tarjan's algorithm are used to analyze the relationships within the network of variables influencing sustainable development and to examine the relationship between these variables and economic vulnerability and resilience. Tarjan's algorithm is looking for a strongly connected graph that can identify the fundamental variables affecting economic vulnerability and resilience and finally determine the maximal graph. The final output of Tarjan's algorithm is n* variables for measuring VR. Tarjan's algorithm divides the variables into two general parts; The first group of variables that causes vulnerability and resilience and the second group of variables that is created as a result of resilience and vulnerability. The initial set of variables in the dimensions of sustainable development includes economic, social, environmental, governance and peripheral dimensions. After identifying the relationships between the 43 variables presented, a graph is drawn that expresses the relationships between the desired variables.
Findings
The results of the algorithm reveal the fact that the resilience of the model is due to the economic and governance dimensions. If the "economic" or the "governance” dimension are specifically removed, the capacity of the directed graph which is resilient to the strongly connected feature will definitely be lost. Since governance and economic dimensions directly affect other dimensions, they are called as control dimensions. On the other hand, social, environmental and peripheral dimensions are considered as contingent dimensions.
Therefore, contingent dimensions are directly dependent and influenced by control dimensions. In this research, the Net Vulnerability and Resilience Index (NVRI) is separated in all dimensions and calculated in the range of -1 and 1. The NVRI time series is shown during the period and based on the sample countries. The results indicate that in all periods, the status of the NVRI index of the G7 countries was better than the MENA countries, and all the G7 members had resilient economies.
Discussion and Conclusion
According to the index calculations, the countries are classified into four states of uncontrolled vulnerable, limited vulnerable, unstable resilient and sustainable resilient. The G7 countries are sustainable and resilient, which means that in these countries, resilience has surpassed vulnerability. The countries of Oman, Kuwait, Saudi Arabia, UAE, Occupied Palestine and Bahrain from the MENA group are also sustainable and resilient.
The main strength of MENA countries, which are in the group of sustainable resilient, is focused on the peripheral dimension and how these countries interact with the global economy. Among these countries, the UAE and occupied Palestine have a more suitable situation. MENA countries are mainly in the pure and uncontrolled vulnerable group. The governance dimension and then the economic dimension are the important factors of the vulnerability of these countries.
The temporal analysis of the index for the selected countries shows that the majority of the countries that are in the sustainable resilient group did not change their situation during the period under review. Iran is an uncontrolled vulnerable during the years 2017-2020, and in all periods, the index in governance and economic dimensions has been negative and vulnerability is more than resilience.
The analysis of the NVRI index examines the strengths and weaknesses of MENA and G7 countries with a sustainable development approach. It helps the policymakers to get strategic suggestions to improve the situation in weaker countries by following the example of the countries that have a better VR state. The goal of quantifying the state of vulnerability and resilience is to achieve sustainable and inclusive growth in accordance with international programs.

Abstract
Introduction: Free radicals in the body create malondialdehyde (MDA), which is one of the most frequent indicators of oxidative stress. Several studies have reported the increase of MDA in inactive persons and individuals with developmental disorders. The purpose of this study, therefore, was to examine whether a program of physical activity reduces MDA in children with intellectual disability.
Methods: Twenty boy students with intellectual disability (7 to 9 years old) voluntarily participated in the study. They were randomly divided into experimental and control groups. The experimental group performed a physical curriculum known as sports, play and active recreation for kids (SPARK) for 12 weeks (3 sessions of 45 minutes per week), while the control group was exempted to participate in the program. The level of MDA in blood samples of all participants was measured before and after the intervention. Repeated measures ANOVA was applied to analyze the data (α = 0.05).
Results: Analysis revealed that there was no significant difference between two groups in pretest (P = 0.698, η2 = 0.009). However, in posttest, the experimental group had significantly lower level of MDA as compared to the control group (P < 0.001, η2 = 0.555).
Conclusion: According to the results, it can be argued that the selected SPARK program reduces MDA which may consequently result in less oxidative stress in children with intellectual disability.
