After synthesizing of MWNT-COOH-based water, measurements on the prepared coolants were made at various concentrations by different experimental methods. While thermal conductivity of nanofluids illustrated a significant increase, the speciﬁc heat capacity of the samples showed a downward behavior with increasing temperature. The viscosity was investigated in different shear rates and temperatures. Interestingly, the speciﬁc heat capacity of all prepared nanofluids was decreased with increasing concentration.

The impacts of Reynolds number and the volume concentration of nanoparticles on the flow and the convective heat transfer behaviour are investigated. The results indicate that the increase in Reynolds number leads to the enhancement of average Nusselt number, and the increase in specific heat in the presence of the nanofluid results in improvement in heat transfer. Also, the presence of the secondary flow in the curve plays a key role in increasing the average Nusselt number and it appears higher than the inlet and outlet tubes.

From the perspective of urban planners and designers, a neighborhood as an urban space has to satisfy various needs of citizens in terms of activities as well as their spiritual requirements. In the research based on the component of environmental quality in one of the neighborhoods with historical value resulting from the theoretical model presented (functional-structural, physical-spatial, and substantive), integrated analysis has been performed on the Khajeh Khezr neighborhood in Kerman. Then, after studying the weaknesses and strengths points of it based on the AIDA model, some mechanisms have been presented to promote environmental quality based on neighborhood organization, and related urban design projects have been defined accordingly. Analyzing the findings shows that inhabitants in the Khajeh Khezr neighborhood are not much satisfied with the quality of the urban environment of the neighborhood. In the research, the descriptive-analytical method and review of texts have been used in the form of library studies, and case study has been applied as well as observation and questionnaire in the form of field studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20quality" title="environmental quality">environmental quality</a>, <a href="https://publications.waset.org/abstracts/search?q=Kerman" title=" Kerman"> Kerman</a>, <a href="https://publications.waset.org/abstracts/search?q=Khajeh%20Khezr" title=" Khajeh Khezr"> Khajeh Khezr</a>, <a href="https://publications.waset.org/abstracts/search?q=neighborhood" title=" neighborhood"> neighborhood</a> </p> <a href="https://publications.waset.org/abstracts/161924/effective-urban-design-on-environmental-quality-improvement-of-historical-textures-a-case-study-on-khajeh-khezr-neighborhood-in-kerman-city" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161924.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">85</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">198</span> Range Suitability Model for Livestock Grazing in Taleghan Rangelands</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Arzani">Hossein Arzani</a>, <a href="https://publications.waset.org/abstracts/search?q=Masoud%20Jafari%20Shalamzari"> Masoud Jafari Shalamzari</a>, <a href="https://publications.waset.org/abstracts/search?q=Z.%20Arzani"> Z.

Advantages and limitations were elicited. All range ecosystems’ components affect range suitability but due to the time and money restrictions, the most important and feasible elements were investigated. From which three sub-models including water accessibility, forage production and erosion sensitivity were considered. Suitable areas in four levels of suitability were calculated using GIS. This suitability modeling approach was adopted due to its simplicity and the minimal time that is required for transforming and analyzing the data sets.

After experimentally measuring thermophysical properties of prepared samples, a computational fluid dynamics study has been carried out to examine the heat transfer and pressure drop of well-dispersed and stabilized nanofluids. The effect of concentration of GNP and Reynolds number at constant wall temperature boundary condition under turbulent flow regime on convective heat transfer coefficient has been investigated. Based on the results, for different Reynolds numbers, the convective heat transfer coefficient of the prepared nanofluid is higher than that of the base fluid. Also, the enhancement of convective heat transfer coefficient and thermal conductivity increase with the increase of GNP concentration in base-fluid. Based on the results of this investigation, there is a significant enhancement on the heat transfer rate associated with loading well-dispersed GNP in base-fluid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanofluid" title="nanofluid">nanofluid</a>, <a href="https://publications.waset.org/abstracts/search?q=turbulent%20flow" title=" turbulent flow"> turbulent flow</a>, <a href="https://publications.waset.org/abstracts/search?q=forced%20convection%20flow" title=" forced convection flow"> forced convection flow</a>, <a href="https://publications.waset.org/abstracts/search?q=graphene" title=" graphene"> graphene</a>, <a href="https://publications.waset.org/abstracts/search?q=annular" title=" annular"> annular</a>, <a href="https://publications.waset.org/abstracts/search?q=annulus" title=" annulus"> annulus</a> </p> <a href="https://publications.waset.org/abstracts/54948/numerical-heat-transfer-performance-of-water-based-graphene-nanoplatelets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54948.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">356</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">195</span> Parametric Studies of Ethylene Dichloride Purification Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sh.%20Arzani">Sh.

This requires the manager to synthesis various information for regular monitoring to define changes trend to get wright decision for sustainable management. So range managers need to use computerized technologies to monitor rangeland, and select. The best management practices. There are four examples of computerized technologies that can benefit sustainable management: (1) Photographic method for cover measurement: The method was tested in different vegetation communities in semi humid and arid regions. Interpretation of pictures of quadrats was done using Arc View software. Data analysis was done by SPSS software using paired t test. Based on the results, generally, photographic method can be used to measure ground cover in most vegetation communities. (2) GPS application for corresponding ground samples and satellite pixels: In two provinces of Tehran and Markazi, six reference points were selected and in each point, eight GPS models were tested. Significant relation among GPS model, time and location with accuracy of estimated coordinates was found. After selection of suitable method, in Markazi province coordinates of plots along four transects in each 6 sites of rangelands was recorded. The best time of GPS application was in the morning hours, Etrex Vista had less error than other models, and a significant relation among GPS model, time and location with accuracy of estimated coordinates was found. (3) Application of satellite data for rangeland monitoring: Focusing on the long term variation of vegetation parameters such as vegetation cover and production is essential. Our study in grass and shrub lands showed that there were significant correlations between quantitative vegetation characteristics and satellite data. So it is possible to monitor rangeland vegetation using digital data for sustainable utilization. (4) Rangeland suitability classification with GIS: Range suitability assessment can facilitate sustainable management planning. Three sub-models of sensitivity to erosion, water suitability and forage production out puts were entered to final range suitability classification model. GIS was facilitate classification of range suitability and produced suitability maps for sheep grazing. Generally digital computers assist range managers to interpret, modify, calibrate or integrating information for correct management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computer" title="computer">computer</a>, <a href="https://publications.waset.org/abstracts/search?q=GPS" title=" GPS"> GPS</a>, <a href="https://publications.waset.org/abstracts/search?q=GIS" title=" GIS"> GIS</a>, <a href="https://publications.waset.org/abstracts/search?q=remote%20sensing" title=" remote sensing"> remote sensing</a>, <a href="https://publications.waset.org/abstracts/search?q=photographic%20method" title=" photographic method"> photographic method</a>, <a href="https://publications.waset.org/abstracts/search?q=monitoring" title=" monitoring"> monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=rangeland%20ecosystem" title=" rangeland ecosystem"> rangeland ecosystem</a>, <a href="https://publications.waset.org/abstracts/search?q=management" title=" management"> management</a>, <a href="https://publications.waset.org/abstracts/search?q=suitability" title=" suitability"> suitability</a>, <a href="https://publications.waset.org/abstracts/search?q=sheep%20grazing" title=" sheep grazing"> sheep grazing</a> </p> <a href="https://publications.waset.org/abstracts/5188/rangeland-monitoring-by-computerized-technologies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5188.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">367</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">193</span> Use of Improved Genetic Algorithm in Cloud Computing to Reduce Energy Consumption in Migration of Virtual Machines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marziyeh%20Bahrami">Marziyeh Bahrami</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamed%20Pahlevan%20Hsseini"> Hamed Pahlevan Hsseini</a>, <a href="https://publications.waset.org/abstracts/search?q=Behnam%20Ghamami"> Behnam Ghamami</a>, <a href="https://publications.waset.org/abstracts/search?q=Arman%20Alvanpour"> Arman Alvanpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamed%20Ezzati"> Hamed Ezzati</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Salar%20Sadeghi"> Amir Salar Sadeghi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the ways to increase the efficiency of services in the system of agents and, of course, in the world of cloud computing, is to use virtualization techniques. The aim of this research is to create changes in cloud computing services that will reduce as much as possible the energy consumption related to the migration of virtual machines and, in some way, the energy related to the allocation of resources and reduce the amount of pollution. So far, several methods have been proposed to increase the efficiency of cloud computing services in order to save energy in the cloud environment. The method presented in this article tries to prevent energy consumption by data centers and the subsequent production of carbon and biological pollutants as much as possible by increasing the efficiency of cloud computing services.

As a result, research on both geological and geotechnical aspects of this type of soil have been in progress for decades. However, considerable natural variability in physical properties of in-situ loess strata even in a single block sample challenges the fundamental laboratory investigations. The reason behind this is that it is somehow impossible to remove the effect of a specific factor like void ratio from fair comparisons to come with a reliable conclusion. In order to cope with this limitation, two types of artificially made dispersive and calcareous loess are introduced which can be easily reproduced in any soil mechanics laboratory provided that all its compositions are known and controlled. The collapse potential is explored for a variety of soil water salinity and lime content and comparisons are made against the natural soil behavior. Trends are reported for the influence of pore water salinity on collapse potential under different osmotic flow conditions. The most important advantage of artificial loess is the ease of controlling cementing agent content like calcite or dispersive potential for studying their influence on mechanical soil behavior. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20loess" title="artificial loess">artificial loess</a>, <a href="https://publications.waset.org/abstracts/search?q=unsaturated%20soils" title=" unsaturated soils"> unsaturated soils</a>, <a href="https://publications.waset.org/abstracts/search?q=collapse%20potential" title=" collapse potential"> collapse potential</a>, <a href="https://publications.waset.org/abstracts/search?q=dispersive%20clays" title=" dispersive clays"> dispersive clays</a>, <a href="https://publications.waset.org/abstracts/search?q=laboratory%20tests" title=" laboratory tests"> laboratory tests</a> </p> <a href="https://publications.waset.org/abstracts/109158/synthesizing-an-artificial-loess-for-geotechnical-investigations-of-collapsible-soil-behavior" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109158.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">196</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">188</span> Effect of Intrinsic Point Defects on the Structural and Optical Properties of SnO₂ Thin Films Grown by Ultrasonic Spray Pyrolysis Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatiha%20Besahraoui">Fatiha Besahraoui</a>, <a href="https://publications.waset.org/abstracts/search?q=M%27hamed%20Guezzoul"> M'hamed Guezzoul</a>, <a href="https://publications.waset.org/abstracts/search?q=Kheira%20Chebbah"> Kheira Chebbah</a>, <a href="https://publications.waset.org/abstracts/search?q=M%27hamed%20Bouslama"> M'hamed Bouslama</a> </p> <p class="card-text"><strong>Abstract:</strong></p> SnO₂ thin film is characterized by Atomic Force Microscopy (AFM) and Photoluminescence Spectroscopies. AFM images show a dense surface of columnar grains with a roughness of 78.69 nm. The PL measurements at 7 K reveal the presence of PL peaks centered in IR and visible regions. They are attributed to radiative transitions via oxygen vacancies, Sn interstitials, and dangling bonds. A bands diagram model is presented with the approximate positions of intrinsic point defect levels in SnO₂ thin films. The integrated PL measurements demonstrate the good thermal stability of our sample, which makes it very useful in optoelectronic devices functioning at room temperature. The unusual behavior of the evolution of PL peaks and their full width at half maximum as a function of temperature indicates the thermal sensitivity of the point defects present in the band gap. The shallower energy levels due to dangling bonds and/or oxygen vacancies are more sensitive to the temperature. However, volume defects like Sn interstitials are thermally stable and constitute deep and stable energy levels for excited electrons. Small redshifting of PL peaks is observed with increasing temperature. This behavior is attributed to the reduction of oxygen vacancies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transparent%20conducting%20oxide" title="transparent conducting oxide">transparent conducting oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=photoluminescence" title=" photoluminescence"> photoluminescence</a>, <a href="https://publications.waset.org/abstracts/search?q=intrinsic%20point%20defects" title=" intrinsic point defects"> intrinsic point defects</a>, <a href="https://publications.waset.org/abstracts/search?q=semiconductors" title=" semiconductors"> semiconductors</a>, <a href="https://publications.waset.org/abstracts/search?q=oxygen%20vacancies" title=" oxygen vacancies"> oxygen vacancies</a> </p> <a href="https://publications.waset.org/abstracts/161707/effect-of-intrinsic-point-defects-on-the-structural-and-optical-properties-of-sno2-thin-films-grown-by-ultrasonic-spray-pyrolysis-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161707.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">85</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">187</span> Engineering in Saudi Arabia: Importance of Communications and Power Engineering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamed%20D.%20Alsharari">Hamed D.

Most chronic musculoskeletal problems and pains can be controlled and reduced with education at an early age. Therefore, with the correct and timely diagnosis of these abnormalities, we can play an important role in their proper treatment and control, and in a way, raise the level of quality of life and positive self-concept in students. The aim of this study was to investigate the relationship between erectile dysfunctions of the upper limbs (head and neck, shoulder, thoracic and lumbar) and the quality of life and self-concept of male students aged 7 to 10 years. The statical population of the study consists of 227 students of shahadat boys’ primary school in khajeh city. Due to the corona pandemic conditions, the research samples were identified after screening and available according to the entrance criteria of the study. To validate the quality of life, the valid WHOQOL-BREF questionnaire will be used for self-concept variables, Dolatabadi, Fatemeh (2007) questionnaire, and for physical screening, a checkerboard, plumb line, and flexible ruler will be used. There is a negative and significant relationship between the dimensions of upper limb anomalies and quality of life factors, and also there is a negative and significant relationship between the dimensions of upper limb anomalies and self-concept factors. The results showed that there is a negative and significant relationship between head and neck abnormalities with quality of life and self-concept factors, with a significance level of less than 0.05 in male students aged 7 to 10 years. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=upper%20limb%20erectile%20dysfunction" title="upper limb erectile dysfunction">upper limb erectile dysfunction</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20life" title=" quality of life"> quality of life</a>, <a href="https://publications.waset.org/abstracts/search?q=self-concept" title=" self-concept"> self-concept</a>, <a href="https://publications.waset.org/abstracts/search?q=erectile%20abnormalities" title=" erectile abnormalities"> erectile abnormalities</a> </p> <a href="https://publications.waset.org/abstracts/158626/relationship-between-upper-extremity-erectile-abnormalities-with-quality-of-life-factors-and-physical-self-concept-in-boy-students-7-to-10-years" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158626.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">93</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">183</span> Size Distribution Effect of InAs/InP Self–Organized Quantum Dots on Optical Properties </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelkader%20Nouri">Abdelkader Nouri</a>, <a href="https://publications.waset.org/abstracts/search?q=M%E2%80%99hamed%20Bouslama"> M’hamed Bouslama</a>, <a href="https://publications.waset.org/abstracts/search?q=Faouzi%20Saidi"> Faouzi Saidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hassan%20Maaref"> Hassan Maaref</a>, <a href="https://publications.waset.org/abstracts/search?q=Michel%20Gendry"> Michel Gendry</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Self-organized InAs quantum dots (QDs) have been grown on 3,1% InP (110) lattice mismatched substrate by Solid Source Molecular Beam Epitaxy (SSMBE).

Several general solutions have been proposed in the past, but these are largely computationally intensive, leading to complex implementations. In this paper, we propose a relatively simple iterative solution, which provides good results in relatively few iterations, using fixed precision arithmetic. An additional advantage is that complex digital blocks, such as dividers and square root, are not required. Thus, the proposed solution may be implemented in relatively simple hardware. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=OFDM" title="OFDM">OFDM</a>, <a href="https://publications.waset.org/abstracts/search?q=DVB-T2" title=" DVB-T2"> DVB-T2</a>, <a href="https://publications.waset.org/abstracts/search?q=I%2FQ%20imbalance" title=" I/Q imbalance"> I/Q imbalance</a>, <a href="https://publications.waset.org/abstracts/search?q=I%2FQ%20mismatch" title=" I/Q mismatch"> I/Q mismatch</a>, <a href="https://publications.waset.org/abstracts/search?q=iterative%20method" title=" iterative method"> iterative method</a>, <a href="https://publications.waset.org/abstracts/search?q=fixed%20point" title=" fixed point"> fixed point</a>, <a href="https://publications.waset.org/abstracts/search?q=reduced%20complexity" title=" reduced complexity"> reduced complexity</a> </p> <a href="https://publications.waset.org/abstracts/1821/reduced-complexity-iterative-solution-for-iq-imbalance-problem-in-dvb-t2-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1821.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">541</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">178</span> Study on the Stages of Knowledge Flow in Central Libraries of Tehran Universities by the Pattern of American Productivity & Quality Center</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Reza%20Asnafi">Amir Reza Asnafi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Tajabadi"> Ehsan Tajabadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Hajizeinolabedini"> Mohsen Hajizeinolabedini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study is to identify the concept of knowledge flow in central libraries of Tehran universities in by the pattern of American Productivity & Quality Center (APQC). The present study is an applied and descriptive survey in terms of its purpose and the methodology used. In this study, APQC framework was used for data collection. The study population is managers and supervisors of central libraries’ departments of public universities of Tehran belonging to the Ministry of Science, Research and Technology. These libraries include: Central Libraries of Al-Zahra University, Amir Kabir, Tarbiat Modarres, Tehran, Khajeh Nasir Toosi University of Technology, Shahed, Sharif, Shahid Beheshti, Allameh Tabataba'i University, Iran University of Science and Technology. Due to the limited number of members of the community, sampling was not performed and the census was conducted instead. The study of knowledge flow in central libraries of public universities in Tehran showed that in seven dimensions of knowledge flow of APQC, these libraries are far from desirable level and to achieve the ideal point, many activities in the field of knowledge flow need to be made, therefore suggestions were made in this study to reach the desired level. One Sample t Test in this research showed that these libraries are at a poor level in terms of these factors: in the dimensions of creation, identification and use of knowledge at a medium level and in the aspects of knowledge acquisition, review, sharing and access and also Manova test or Multivariable Analyze of Variance proved that there was no significant difference between the dimensions of knowledge flow between these libraries and the status of the knowledge flow in these libraries is at the same level as well. Except for the knowledge creation aspect that is slightly different in this regard that was mentioned before. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=knowledge%20flow" title="knowledge flow">knowledge flow</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20management" title=" knowledge management"> knowledge management</a>, <a href="https://publications.waset.org/abstracts/search?q=APQC" title=" APQC"> APQC</a>, <a href="https://publications.waset.org/abstracts/search?q=Tehran%E2%80%99s%20academic%20university%20libraries" title=" Tehran’s academic university libraries "> Tehran’s academic university libraries </a> </p> <a href="https://publications.waset.org/abstracts/129175/study-on-the-stages-of-knowledge-flow-in-central-libraries-of-tehran-universities-by-the-pattern-of-american-productivity-quality-center" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129175.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">164</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">177</span> Studying the Impact of Agricultural Producers Support Policy in Export Market</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yazdani%20Saeed">Yazdani Saeed</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafiei%20Hamed"> Rafiei Hamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Nekoofar%20Farahnaz"> Nekoofar Farahnaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Governments Policies play a major role in national and international Markets.
