  "Muhammad Ali Khorasani" with a nickname and pseudonym called "muezzin" is one of the 11th Hegira mystic and is one the Aqtab-e Zahabiye who has legated a Divan of nearly 3700 verses. The sage Khorasani was born in Säbzĕvär and joined to Zahabiye sect in his youth and after Sheikh Hatam Zaravandi, leader of the sect on that time, was assigned to this position. Khorasani muezzin like many mystic-poets applied his mystical thoughts in poetry arena. Though he lived in 11th Hegira, his poems can be regarded as the continuation of Iraqi Mystical style poem. His poems are simple, fluent and adsorbent. There are lots of words about true love in his poems, and Sufi thoughts have deep reflection in its core and surface. His divan was not corrected and published, but the author has corrected it based on its 4 versions as his MA thesis and has used many of wise guidance of thoughtful master, Dr. Alireza Fuladi. It is tried in this essay to introduce this poet and provide an outline of his thoughts which are clearly and brilliantly obvious in his poems for readers, so that they can have at least a brief familiarity with this poet of Ahl-e Beit of Prophet and his thoughts.

  the presidential elections in Iran have always surprised the political analysts and experts. Through the analytical investigations of 11th presidential elections of Iran , both at the level of Iranian and also foreign analysts, it has become clear that the most of this surprise is due to the one-factor and one- dimensional analyses and there is no model that can investigate all effective layers and dimensions in the elections’ results. So this essay is determined to study the 11th elections by means of 3-layer model that its most internal layer is discursive level of elections, its medial layer is based on the relative deprivation theory that tries to illustrate the social and economic circumstances of society and its outset layer, studies the description of the field level of elections and presents the personal, political and social factors that are effective in the elections results Manuscript profile

  IEEE 802.11e is standardized to enhance real time multimedia applications’ quality of service (QoS). This standard introduces two access mechanisms called Enhanced distributed channel access (EDCA) and HCF Controlled Channel Access (HCCA) as well as four Access Categories (ACs) for different types of applications. Each AC has four adjustable parameters : Arbitrary Inter-Frame Space Number(AIFSN), minimum Size of Contention Window(CWmin), maximum size of Contention Window (CWmax), and TXOP_limit. A TXOP_limit (TXOP) is time interval, in which a wireless station can transmit a number of frames consecutively, without releasing the channel and any further contention with other wireless stations. TXOP improves network throughput as well as service differentiation. Proper TXOP adjustment can lead to better bandwidth utilization and QoS provisioning. This paper studies the determination of TXOP in EDCA mode of IEEE 802.11e using a game theory based approach called GDTXOP. Based on GDTXOP, each wireless node chooses its appropriate TXOP according to its queue length and media access delay. OPNET simulator simulated the proposed method and its accuracy is evaluated and verified. The results of the simulation indicate that tuning TXOP appropriately improves both channel utilization for all levels of traffic priority and fairness. This improvement does not impair the quality of high-priority traffics. The proposed approach improves channel utilization, while preserving fairness and efficiency in WLANs and minimizing selfishness behaviours of stations in a distributed environment. Simulation results show the proposed method improves fairness while not disrupting the quality of service. Manuscript profile

  Nowadays, with attention to soar in the number of network users, it is necessary to find new approaches to revolutionize network operation. Vehicular ad-hoc networks are bound to play a pivotal role in communication, therefore raising the traffic in the network, using only WiFi is unlikely to address this problem. Vehicles could use SDN and other networks such as 4G as well as 5G to distribute traffic to different networks. Moreover, many approaches for handling different data types are inappropriate due to the lack of attention to the data separation idea. In this paper, we proposed a control scheme called Improve Quality of Service in DTN and Non-DTN (IQDN) which works based on vehicle communication infrastructure using SDN idea. IQDN separates data to Delay-Tolerant Data (DTD), and Delay-Intolerant Data (DID) where the former buffers in a vehicle till the vehicle enters an RSU range and sends DTD using IEEE 802.11p. DID packets are sent by cellular networks and LTE. To transmit DTD via IEEE 802.11p, the network capacity is evaluated by SDN. If that network has room to transmit the data, SDN sends a control message to inform the vehicle. Simulations show that sending data over RSU and LTE increases the throughput and decreases the congestion, so the quality of service improves. Manuscript profile

  In this study the relationship between petrographic studies (microfacies, environment of deposition and diagenesis) and petrophysical data of core analysis in order to identify reservoir quality of the Jahrum Formation in well no. 11 at the Golkhary oil field. The Golkhary oil field is located at the west of Qatar-Kazerun fault, in between Binak and Nargesi oil fields. The Jahrum Formation consists of limestone, dolomite limestone and dolomite. Petrographical studies accomplish in two parts microfacies studies led to the recognition of 9 microfacies that were deposited in 3 facies belt tidal flat, lagoon and open marine environment. In diagenesis studies the most important factors included bioturbation, micritization, mechanical compaction, secondary porosity, secondary anhydrite cement, calcite burial cement, stylolites and solution seams, replacement dolomite, dolomite cement and hydrocarbon shows. Porosities identified are intercrystalline, intergrain, intrafossil and intragrain, moldic, fracture, solution along stylolite, solution enlarge and shelter. The results of this study shows that Grain supported MF3 (Bioclast Nummulitidae Rotalia wackestone/ packstone/ grainstone) and MF4 (Bioclast Nummulitidae Orbitolites packstone/ grainstone/ floatstone) due to the presence in the environment energetic, micrite absence, lack of widespread cement, presence of effective porosities includes intergrain porosity and intercrystalline porosity identified are reservoir microfacies. Petrophysical data with high levels of permeability and effective porosity between these two microfacies is the confirmation of the results of petrographic studies. Manuscript profile

  In the scientific interpretation of the Qur'an, the verses whose miraculous aspects are examined are more important. The miracle of the Quran is one of the favorite topics of commentators and religious researchers in the present era; Because by means of it, the truth of this divine religion can be proved. The presentation of religious topics, especially the miracles of the Qur'an, in the classroom can also be of great help in attracting students to religious education. So far, various scientific points from the verses of the Holy Quran have been discovered in connection with the topic of human creation. In this research article, based on library sources, a comparative comparison is made between the opinions of commentators, linguists and embryologists about verse 189 of Surah Al-A'raf, and using solid reasons, it is shown that the Quran tells a secret about the way in which the egg is contained by the sperms, fertilization between Their nucleus and zygote formation is mentioned. It should be mentioned that we have used the materials related to the subject mentioned in the 11th grade biology textbook for the purpose of effective and attractive teaching, so that students can be introduced to Quranic concepts through it.

  regions of the country Afshin kasalaei Meisam mousaaei Reza Ali Mohseni Khalil Mirzaie Bahram Ghadimei Abstract The present study investigates the factors affecting capital absorption in less developed regions of Iran during the years 1300-1400. To investigate the above issue, the effect of independent variables (economic, social, cultural, legal and political indicators) on the dependent variable (the amount of capital surplus absorption) is examined. The statistical population in this study is 31 provinces of the country, among which 4 provinces have less (less developed) (Kurdistan, Hormozgan, West Azerbaijan and Sistan and Baluchestan) according to the studies (based on three principles). Opportunities, capabilities and achievements) have been purposefully selected as a statistical sample. Research method this research is a mixed method (quantitative-qualitative) and uses fuzzy Delphi techniques, TOPSIS-factor analysis, structural-interpretive equations and structural equations. Quantitative and qualitative data were collected by the mentioned methods and analyzed and explained using statistical tests. This study was conducted with the aim of "designing a model and mechanisms to increase the ability to attract surplus capital in less developed (less privileged) areas and with the assumptions of economic, socio-cultural, political and legal indicators on the impact of surplus capital and the results show This is because the hypotheses are confirmed and the independent variable affects the dependent variable.

  With the formation of the Safavid dynasty and the formalization of the Shia religion, followed by the request of scholars to publish knowledge, a suitable platform was formed in the 11th century. More than eighty percent of the explanations of the Arbaa books were written in this time, in terms of quantity and quality, among which the principles of Sufi have been given more attention than other books. Count the hadith. His careful look at the religious narrations caused him to change the purely narrating and devotional view of the texts. According to Allameh Shearani, this description has left a deep impact on the interpretations and has transformed them. Mullah Saleh Mazandarani also wrote a commentary on the sufficient principles after Mullah Sadra. This analytical, descriptive and applied article by Baroosh examines the effective platforms in the writing of hadith works in the eleventh century in order to reveal by analyzing the methods of hadith jurisprudence in the commentaries of Mulla Sadra and Mulla Saleh that the hadith activities of this period were not only quantitative in terms of quantity but also rich in terms of quality. The use of the rules of logic and philosophical and rational discussions, the approach of interpretation and translation, paying attention to conveying the meaning and resolving the conflict of narrations are some of the prominent features of this explanation.
