Drawing the scientific collaboration maps is very important for analyzing and identifying scientific collaborations in different subject areas of science. Therefore, the aim of this was to scientometrically analyze intellectual capital articles and draw the scientific collaboration map in this area.

This applied study was performed using a scientometric approach. The statistical population of the study included 2077 intellectual capital articles indexed in the Web of Science (WoS) citation database during 1985-2018. In addition, the VOSviewer software was used to draw the scientific collaboration maps of authors, countries, journals, organizations and keyword co-occurrences.

The findings showed that the publication and citation trend of the intellectual capital articles in the WoS was ascending; Dumay with 30 citations and 620 documents and Bontis with14 documents and 463 citations. The most cited authors, countries, universities, journals and keywords in this field were in the following order: Countries including United States (361 documents and 5745 citations), the United Kingdom (199 documents and 3492 citations) and Spain (171 documents and 1591 citations); Universities like Macquarie University of Australia (32 documents and 467 citations) and McMaster University of Canada (26 documents and 697 citations); Journals such as Intellectual Capital (127 documents), Knowledge Management Research and Practice (53 documents), Management Decision (881 citations) and Expert Systems with Applications (786 citations); and keywords of Capital (901 documents and 11229 citations), Intellectual (817 documents and 9041citations) and Knowledge (267 documents and 2763 citations). Moreover, the keyword co-occurrence map was more coherent than the co-citation and co-authorship map of the authors, universities, countries and journals.

Citation and scientific collaboration in the intellectual capital articles despite the upward trend is weak; therefore, policymakers in this field should make the necessary plans to improve and strengthen scientific collaboration.

This study is a scientometric analysis of scientific products of the Islamic civilization.

This is an applied research and done by scientometric approach. The statistical population of the study includes 337 indexed scientific outputs in the field of the Islamic civilization in the Web of Science database during 1986-2018. The data gathering tool is a checklist and information analysis tools are HisCite, VOSviewer, and Excel softwares.

The findings showed that the process of scientific outputs publishing was ascending with a slight fluctuation in different years, and most of the subjects of the scientific outputs are respectively in the areas of political science, religion, and sociology. Morever, the United States, Turkey, England and Malaysia, as well as Barilan, Colombia and Ankara universities, and the Journal of Peace Research had the largest publication and citation of scientific outputs. In addition, findings showed that Jonathan Fox had the most article publication among the authors, but the citation collaboration of the authors from countries and organizations is generally lower, and the co-occurrences network of keywords was also more dispersed and the keywords of Islam and Islamic civilization have the most cooccurrences.

The results showed that local citations to scientific outputs are much lower than global citations, and scientific collaboration among countries, organizations, and authors is also lower. Therefore, Islamic civilization policy-makers in different countries, especially Muslim countries, should strengthen and improve scientific cooperation locally and internationally and create the necessary incentives to increase scientific collaboration among authors, countries and organizations.

The non-recurrent laryngeal nerve (NRLN) is an infrequent variant of inferior laryngeal nerve that takes an unusual course. Since this is a rare anatomic variation, operations on these patients carry a great risk of laryngeal nerve injury.

A 25-year-old woman with papillary thyroid carcinoma and cervical lymphadenopathy underwent total thyroidectomy and bilateral neck dissection levels II – VI. It was noted intraoperatively that right inferior laryngeal nerve was a NRLN and right common carotid artery originated directly from the aorta and right brachiocephalic artery was absent. The nerve was preserved and patient underwent an uneventful surgery. She was well in her follow-up visits, her voice was good and both of her vocal cords were mobile on indirect laryngoscopy examination.

Although NRLN is a rare anatomic variation, surgeons should always think twice about this finding whenever right recurrent laryngeal nerve cannot be found according to anatomical landmarks intra-operatively.

Benign multicystic peritoneal mesothelioma (BMPM) is a rare disorder that occurs predominantly in reproductive-aged women. A 42-year-old male referred to our emergency department in Mousavi Hospital of Zanjan University, suffering from diffuse abdominal pain. He mentioned a history of operation two years ago, during which cystic tumors had been removed from his abdomen.
A cytoreductive surgery was performed. The pathologic study confirmed the diagnosis of BMPM and immunohistochemical analysis verified the negative expression of CD34 marker and positive expression of calretinine in the cyst lining. Preoperative diagnosis of BMPM is difficult and definitive diagnosis requires histological evaluation of the specimen. Due to the of the rarity of BMPM, the need for familiarity with this benign but aggressive tumor is felt.

Aim: The aim of this research is to study the Middle Eastern countries station and the determination of powerful information, dependent states and buffer states countries, based on scientific production and scientific cooperation in the geopolitics of information. This research is an applied and scientometrics applied objective that has been done by documentary methods and content analysis. The research community is a study of the 16 Middle Eastern countries based on the quartile of scientific production and regional and trans-regional scientific cooperation ,2008-2017. Data is extracted from the scopus, the world bank and the palestine center for statistics databases, and Excel and SPSS software has been used for data analysis.
Findings: According to the findings, Turkey, Saudi Arabia, Iran and Egypt, respectively, are in the first to fourth States in the Middle Eastern Geopolitics of information, and by allocating more than 75% of the quartile (Q3), the indicators are among the most powerful information countries. The countries of, Israel, Qatar, United Arab Emirates, Jordan, Oman, Kuwait, Iraq, and Palestine respectively, States fifth to twelfth in the Middle Eastern, and make up 25 to 50 percent of the quartile (Q2) indicators of the dependent countries. And the four countries of Lebanon, Bahrain, Yemen and Syria, ranked thirteenth to sixteenths of the Middle Eastern's geopolitics of information, and with 25 percent of the quartile (Q1), the indicators form Middle Eastern buffer states countries. .

To investigate, understanding and predicting dynamic fracture behavior of a cracked body, dynamic stress intensity factors (DSIFs) are important parameters. In the present work interaction integral method is presented to compute static and dynamic stress intensity factors for three-dimensional cracks contained in the functionally graded materials (FGMs), and is implemented in conjunction with the finite element method (FEM). By a suitable definition of the auxiliary fields, the interaction integral method which is not related to derivatives of material properties can be obtained. For the sake of comparison, center, edge and elliptical cracks in homogeneous and functionally graded materials under static and dynamic loading are considered. Then material gradation is introduced in an exponential form in the two directions in and normal to the crack plane. Then the influence of the graded modulus of elasticity on static and dynamic stress intensity factors is investigated. It has been shown that, material gradation has considerable reduce influence on DSIFs of functionally graded material in comparison with homogenous material. While, static stress intensity factors can decrease or increase, depend on the direction of gradation material property.

Heparin can induce a number of complications, including decreased number of platelets and inducing anti-platelet antibodies. This study was designed to compare these adverse effects between low molecular heparin and unfractionated heparin in patients diagnosed as deep vein thrombosis. In a clinical trial study, 124 cases diagnosed as deep vein thrombosis were divided randomly in 2 groups, 62 in each one. The first group was treated with enoxaparine and the 2nd treated with unfractionated heparin. Changes in platelet number and any new development of anti-platelet antibodies were assessed and compared between the groups. The cases in the 2 groups were compared regarding age, sex, and the platelet number. The decrease in platelet number was statistically significant in the unfractionated heparin while the 2nd group did not have any statistically significant decrease. The difference between the two groups was statistically significant regarding platelet count. The introduction of new anti-platelet antibody was significant in the unfractionated heparin group but not the enoxaparin group. None of the cases had a platelet number less than 100.000/ml. The study suggests that the enoxaparin is superior to unfractionated heparin regarding production of anti-platelet antibodies and decrease in platelet count. Serial platelet counts and the risk of thrombocytopenia should be considered when admininstering unfractionated heparin in deep vein thrombosis cases.
