In this paper, first we study the elementary properties of double graphs and then we present explicit formulas for a few topological indices on double graphs, i.e., of graphs which are the direct product of a simple graph $G$ with the graph obtained by the complete graph $K_{2}$ adding a loop to each vertex. Finally, we compute the eccentric connectivity index of the double of lexicographic product and complete sum of two graphs.

One of the most important issues related to the agricultural sector is the lake of farmer’s capital which has always been one of the factors limiting the growth of this sector. The proper management of credits can play an important role in the growth of the agricultural sector and contribute to national development. This study has been conducted to investigate the role of facilities and credits of Bank Keshavarzi (agriculture bank) on agronomy development in Kangavar Township. The study population consisted of all villagers that used facilities and credits of Bank Keshavarzi (in years 2011-2017; N=1000) which by using multi-stage sampling 213 of them were selected. Data was collected using a questionnaire. The face and content validity of the questionnaire had been confirmed by a panel of experts and key informants before the pre-test stage. The reliability of the instrument was assessed by conducting a pilot study among 30 samples out of the original sample. The reliability of instrument for the all sections based on Cronbach's alpha coefficients value (0.65- 0.87) shows an acceptable level of internal consistency. The SPSS software was used for data analysis. The results of the correlation analysis showed that there was a significant correlation between annual income and annual agricultural income with agronomy sector development and there was a positive and significant correlation between facilities and credits of |Bank Keshavarzi with agronomy sector development. However, the results of the correlation analysis showed that there wasn’t a significant correlation between facilities and credits of Bank  Keshavarzi with livestock and horticulture development.

Cyber attacks have been increasing rapidly over the years, sometimes resulting in large financial losses for businesses, recoveries, regulatory sanctions, as well as collateral damage, such as reputation and trust. In this regard, the maritime sector, which until now was considered safe due to the lack of internet connectivity and the isolated nature of ships at sea, is witnessing a 900% increase in cyber security breaches in operational technology as we enter the digital age. Although some research is being done in this area, maritime cyber security has not been explored in depth. Hence, this research scrutinizes the cyber security landscape in the maritime sector with the aim of highlighting security problems and challenges. Then, it describes and analyzes possible mitigation measures that can be used in advance to prevent such attacks. Finally, several challenges and open problems for future research are discussed.

The research aims to investigate and analyze the challenges of cyber security in the marine and commercial ships in a descriptive-analytical way.

IT and OT systems in modern ships should be prepared with more advanced security measures due to their high vulnerability to cyber threats. In this article, we discuss some possible countermeasures that could reduce potential cyberattacks and make the transportation industry a tough target, such as implementing a new security standard that would reduce the number and scope of cyberattacks. put. However, many security challenges remain unsolved, especially with the increasing use of autonomous and semi-autonomous vessels.

Arbitration is one of the most important dispute resolution methods that has become increasingly important. In the present paper, an attempt has been made to examine the economic reasons for the effectiveness of arbitration in Iran's legal system and the challenges facing it.

This paper is descriptive and analytical and library method was used to collect data.

Ethical considerations:

 In this paper, the originality of the texts, honesty and trustworthiness are respected.

The findings indicate that reducing litigation costs and the role of arbitration in resolving commercial disputes is the most important reason for the efficiency of arbitration in Iran's legal system. But the effectiveness of arbitration in Iranian law faces challenges. The legal structure of the arbitration institution in Iran faces a lot of ambiguities and gaps due to the dual structure of the laws, and this has caused inadequacies and challenges regarding the arbitration institution, and as a result, it has reduced the public desire to refer a dispute to arbitration. One of the most important legal weaknesses in arbitration is the lack of clear determination of independence and impartiality in the case of a special arbitrator, conflict in jurisdiction and arbitration, as well as legal gaps in the expert opinion issued by the arbitrator and legal ambiguity regarding the issuance of a temporary order and fulfillment of demand.

In the findings, gaps and legal weaknesses were mentioned and as a conclusion It is necessary to resolve the legal challenges and weaknesses, and most importantly, to change the public attitude towards arbitration and to improve the status of arbitration.

Security is the bedrock of the growth of any society and people have always used all their material and spiritual tools and facilities throughout history to realize it and formed the government for this reason. One of the disturbing factors of security in Economic dimensions, smuggling of goods into the country without any rules. From the political point of view, goods smuggling is considered a negative point in countries; From the social aspect, smuggling of goods causes disruption of the social and income balance among the layers of the society and creates a rich and at the same time hated class in the society. From the economic point of view, the smuggling of goods also inflicts fatal blows on the economy of the society. This research was conducted with the aim of investigating the effect of smuggling of goods on the economic security of the country. 

The present research is applied in terms of purpose and descriptive-correlation in terms of research design and method, and the statistical population includes the collective employees of the military-mission units of the police command headquarters of Bushehr province, which is 120 people using Cochran's table. They were chosen as a sample and in a simple random way. The tool for collecting information was a questionnaire made by the researcher, and content validity was used to check the validity of the questionnaire, and the reliability of the tool was checked by Cronbach's alpha test and calculated as 0.92.

The results showed that goods smuggling has an impact on the dimensions of economic security in such a way that with the increase in goods smuggling, the level of public participation, political stability, health of the legal system, health of the administrative system, quick access of countries to essential and strategic goods of the country and the rate of economic growth The country is declining. On the other hand, with the increase in the smuggling of goods, the level of political violence in the country increases.

In this study, the effect of penetration and temperature changes on the performance specifications of bitumen was investigated experimentally. In this regard, it was ensured that the bitumens were obtained from a constant raw material and oxidation process at different times from the reactor. Experiments were carried out on bitumen with different penetration grades of 35, 40, 50, 55 and 60 (1⁄10 mm ). The effect of changes in the penetration grades and temperature were investigated on various quality parameters of bitumen, including bitumen specifications at high and medium temperatures, after initial and long-term aging, using rheological behavior tests by dynamic shear rheometer, thin film oven and pressurized aging vessel and the corresponding comparison diagrams were drawn. The results show that the rutting resistance or permanent deformation of bitumen in both binder and residual bitumen of thin film oven test was decreased with increasing temperature in a bitumen with a constant penetration grade and also increasing the penetration grade at a constant temperature. The Fatigue cracking index in the residual bitumen of the thin film oven and pressurized aging vessel, was decreased with increasing temperature in a bitumen with a constant penetration grade and also increasing the penetration grade at a constant temperature.

Psychological variables in women due to their closer proximity to the environment have a greater role in their cooperation with the environment. Therefore, this study has been conducted with the aim of investigating the role of psychological variables on the rural women empowerment in environmental conservation. In order to accomplish the objectives of this study, data were collected from a sample of 384 rural women in Chaharmahal and Bakhtiari Province in Iran. A questionnaire was used as the research instrument. Reliability and validity of the survey instrument were further evaluated. Face and content validity of the questionnaire were confirmed by panel of experts and key informant before the pre-test stage. The reliability of instrument was assessed by conducting a pilot study among 30 samples out of the original sample. The reliability of instrument for the all sections based on Cronbach's alpha coefficient value (more than .80) revealed acceptable level of internal consistency. Data analysis was performed by SPSS24 and AMOS22 software. The collected data was analyzed using structural equation modeling technique. The results based on direct structural model showed that there is a positive significant relationship between psychological variables such as autonomy, self-esteem and self-efficacy with the dependent variable of environmental conservation. Also, based on the mediation structural model, it was found that rural women empowerment variable had a mediating role in the relationship between psychological variables and environmental conservation. Therefore, considering the impact of rural women's empowerment on environmental protection, it is suggested that courses and workshops be held to increase the empowerment of rural women by promoting psychological variables.

Oral and dental health is one of the most important health indicators in the society. Decayed Missing Filled Teeth (DMFT) index and Community Periodontal) Index of Treatment Needs (CPITN) are the most important indicators used in oral health evaluation. The aim of this study was to evaluate the oral health status of 12-years-old students of Gonabad and Bejestan and its relationship with their drinking water and some related factors. This cross-sectional analytical study was performed on 760, 12 years old students of Gonabad and Bejestan in during the educational years of 2018- 2019. Demographic information, eating and drinking and health habits were collected by a questionnaire and oral health status was recorded in a checklist by a clinical examination. Fluoride and calcium parameters of drinking water were measured 2351 and 8652, according to the standard of Iranian Institute of Standards and Industrial Research.Data were analyzed by SPSS softwareV.20. The mean DMFT index of students in Gonabad and Bejestan were 0.89±1/26 and 0.86±1/12.The mean drinking water fluoride of Gonabad and Bejestan were 0.39±0/298 mg/L and 0.21±0/042 mg/L. The mean calcium of drinking water in Gonabad and Bejestan were 12.86±9/42 mg/L and 10.26±1/07 mg/L. According to the statistical tests, there was a significant relationship between DMFT index and amount of drinking water per day, drinking water fluoride and dental floss usage (P-value <0/05(.There was also a significant relationship between CPITN with toothbrush (P-value <0/05). As drinking water fluoride and dental floss that among the day are associated DMFT index, drinking water fluoride should be kept within the standard range and oral health care techniques such as using toothbrush and dental floss must be taught to students.

The health of a bank helps to maintain the trust and confidence of the bank and also the interests of the beneficiaries. But balancing the interests of all stakeholders requires improving corporate governance in banks. Given the importance of the issue, this paper examines the effect of corporate governance on bankschr('39') regulatory rankings. For this purpose, the required criteria have been measured using the financial statements of the Iranianchr('39')s private banks in the period of 2006-2018 and the principles of the Basel Committee in the field of corporate governance. Then, the panel data method and Kaplan Meier were used to measure the effect of corporate governance on the regulatory rank.The results indicate good transparency and disclosure have positive and significant effect and board of directors has negative and significant effect on improving bankschr('39') regulatory rating. But good accountability has not effect on bankschr('39') regulatory rating. The degree of effectiveness of the board of directors is more important than other criteria of good transparency and disclosure, good accountability and transparency. Comparing with a good measure of accountability has a greater impact than others on improving bankschr('39') regulatory rating. Also, the more banks comply with corporate governance principles, the less time they will have to improve their regulatory rank. This is a shorter time for the board to be effective.

Project financing means financing the construction and operation of a project or refinancing a large industrial unit. One of the methods of financing is the issuance of securities. There are various types of securities that represent securities and are transferable, and each of these types is used in a special way in the financing process. Among the bonds that can be issued in the project financing process, we can mention bonds, stocks, securities backed by assets and sukuk. Today, due to the limitations of governments and banks in financing the project, the issuance of securities is recognized as an alternative method. The accumulation of micro- capital of individuals, the anonymity of buyers of securities, non-interference in project management, flexibility in financing terms and access to an endless source of liquidity are among the undeniable benefits of securities and the use of this tool in financing Has gradually expanded the project. The issuance of these bonds in the project financing process is different from the corporate financing and the method of risk allocation, repayment of principal and interest of the bonds, the responsibility of the publishers, the duties of the intermediary and the method of issuance are unique in some cases. Is.

Today, environmental degradation and the lack of awareness of the farmers about its issues is one of the major challenges in rural areas .Therefore, sustainable environmental behavior in these areas is very important to achieve national development goals. Therefore, this study has been conducted with the aim of investigating the mediation role of intention in analysis of the factors influencing sustainable environmental behavior among farmers. The study population was consisted of farmers in Zanjan township that according to Cochran’s formula, 300 of them were selected by multistage sampling method. A questionnaire was used as research tools. Face and content validity of the questionnaire had been confirmed by panel of experts and key informant before the pre-test stage. The reliability of instrument was assessed by conducting a pilot study among 30 samples out of the original sample. The reliability of instrument for the all sections based on Cronbach's alpha coefficients value (in the range of 0.72 to 0.88) shows acceptable level of internal consistency. Data analysis was performed by SPSS24 and AMOS22 software. The collected data was analyzed using structural equation modeling technique. The results based on direct structural model showed that there is a positive and significant effect between variables such as subjective norms, perceived behavioral control and environmental attitudes with the dependent variable of sustainable environmental behavior in agriculture. Also, based on the mediation structural model specified that intention variable had a mediation role on the relationship between independent variable with sustainable environmental behavior in agriculture and these variables explained 39% of variances of dependent variable.

Nosocomial infections are one of the most important problems in hospitals and medical centers which cause loss of economic resources increased length of stay in hospitals and mortality. Correct and appropriate use of antiseptic and disinfectants play an important role in reducing infections. In this study the efficacy of the Current Disinfectants on Bacteria Isolated from Different Wards of an Educational Hospital has been studied.

In this cross-sectional study, a total of 245 samples were taken from different wards of Allameh Behlul Hospital in Gonabad. Samples were taken before and after disinfection with disinfectants of Deconnex AF50, Peranacide M1, microzed GPH and Sarphosepte Quicks. Samples were cultured on special culture media and identified by biochemical tests and the number of colonies was determined. Data were analyzed using Wilcoxon statistical test.

In the present study, microbial contamination of different sections showed that the most gram -positive bacteria were isolated included Staphylococcus epidermidis, and the most Gram -negative bacteria were isolated included, Escherichia coli. Mean before and after disinfection in deconox and microzed disinfection was significantly different in all parts (P <0.05). For peranaside disinfection in Internal and NICU sections, and in ICU and Maternity before and after There was no significant difference in disinfection (P> 0/05).

The results of this study showed that Deconex and Microzed were among the most effective disinfectants. Peranaside disinfectant in the maternity and NICU sections, and the Sarphosepte Quicks were also less effective in the Internal and ICU sections, but had good efficacy in other sections.

In most cases before the International Court of Justice (ICJ), the respondents in accordance with the Rules of Court, raise a preliminary objection to the jurisdiction of the Court, the admissibility of the application or other objections. Upholding a preliminary objection in a particular field prevents the Court from exercising its jurisdiction in that field.“Non-existence of dispute” has been one of the most important grounds for preliminary objections to the jurisdiction of the International Court of Justice from the past to the present. Accordingly, the respondent claims that, essentially, there is no dispute between parties in the case at hand. This article examines definition, importance, nature, and requirements of “dispute”. Then the basics of the existence of dispute will be discussed, such as the subject-matter of the dispute (real dispute), its relevance with parties, its determination and objectivity, concurrence and awareness requirements, prohibition of increasing and changing the dispute, threshold of existence of dispute and the burden of proof, in the light of Articles (79), (79bis) and (79ter) of the Rules of Court, its Statute and judicial procedure.

In recent years, continuous awareness has increased on the need to empower rural women to achieve sustainable development. Therefore, this study has been conducted with the aim of investigating the role of rural women empowerment in analysis of the social and economic factors and cultural obstacles influencing local communities’ development. The study population was consist of rural women in Chaharmahal and Bakhtiari province that according to Krejcie and Morgan sample determination table, 384 of them were selected by stratified random sampling method. A questionnaire was used as research tools. Data analysis was performed by SPSS24 and AMOS22 software. The collected data was analyzed using structural equation modeling technique. The results based on direct structural model showed that there is a positive significant relationship between variables such as social participation, social protection and economic factors with the dependent variable of local communities’ development and there is a negative significant relationship between cultural obstacles with the dependent variable of local communities’ development. Also, based on the mediation structural model specified that rural women’s empowerment variable had a mediation role on the relationship between social and economic factors and cultural obstacles with local communities’ development

Methicillin-resistant staphylococci are important causes of nosocomial infections. Due to the presence of these bacteria in hospitals as a significant challenge in hospital infection control, the identification of effective disinfectants against methicillin-resistant staphylococci is necessary. This study was designed to evaluate the effectiveness of common hospital disinfectants against methicillin-resistant staphylococci.

In this cross-sectional study, the effectiveness of 4 surface disinfectant cleaners (Deconex 50 AF, Microzed GP-H, Peranacid M1 and Surfocept quick) against methicillin-resistant staphylococci (10 Staphylococcus aureus, 10 Staphylococcus saprophyticus, and 55 Staphylococcus epidermidis) was evaluated using broth dilution method, disc diffusion assay, and cell viability assay.

The minimum inhibitory concentrations (MICs) and minimum bactericidal concentrations (MBCs) of Peranacid and Surfocept against the isolates were higher than those of Deconex and Microzed. The results of disk diffusion assay showed that staphylococcus strains exhibited greater inhibition zone diameter than other disinfectants at different concentrations of Deconex and Microzed. According to the results of cell viability assay, S. aureus, S. epidermidis, and S. saprophyticus isolates did not grow at three concentrations (0.5%, 1% and 2%) of Deconex, Microzed, and Peranacid, respectively.

Deconex and Microzed had more antimicrobial properties than the 2 other agents and methicillin-resistant staphylococcus isolates had a higher resistance to both Peranacid and Surfosept

Today, with the development of technology, cybercriminals take actions with intent, revenge or entertainment. Behaviors such as spying on someone else, threatening, defaming, spreading false information about another, disseminating another's confidential information, gathering information from another, stealing financial information, requesting a visit, victimization, sending unsolicited messages, and similar behaviors in some countries It is known. For this reason, it is necessary to provide appropriate solutions to prevent the occurrence of such cybercrimes that are detrimental to public security or national security. The present article seeks to identify the factors that increase this crime in the geographical area of Bushehr between 1994 and 1998.

The statistical population in the present study includes 2 data on 10% of Internet harassment between 1994-98 in Bushehr city. Which is analyzed and surveyed. Our sampling is 100 people in total. Also, in order to analyze the data, structural equation modeling with partial least squares approach and SPSS software has been used.

The findings showed that the variables of expansion of use, uncontrollability, various features of the Internet and the personality of the perpetrator have a significant effect on increasing crime. The findings of this study confirm the relationship between age and crime.

 Cognitive impairment, an important side effect of electroconvulsive therapy (ECT), may be related to the release of prostaglandins in the brain. Cyclooxygenase-2 (COX-2), constitutively expressed in the CNS, has a functional role in glutamate-mediated learning and memory. The goal of this pilot, double-blind, placebo-controlled trial was to evaluate the effects of the selective COX-2 inhibitor celecoxib on the adverse cognitive effects of ECT. Twenty patients diagnosed with the major depressive disorder for which ECT was indicated as a treatment for their current episode randomly received either celecoxib (200 mg orally twice a day, a total dose of 400 mg/day) or placebo. All patients underwent the same protocol for anesthesia and ECT procedures. The patients received celecoxib or the placebo for the whole period of ECT treatment, starting the day before ECT and continuing until the sixth (last) session of ECT. The Wechsler Mental Scale-III (WMS-III), the Mini-Mental Scale Examination (MMSE), and Stroop Color test were used to assess cognition before the first session and after the first, third and sixth sessions of ECT. Hamilton rating scale for depression was also used for the assessment of depression before and after the trial. Our data showed that celecoxib group did not have significant improvement in cognition based on WMS-III or MMSE scores. There was an improvement in the Stroop Color test but not statistically significant. Our results demonstrated that although celecoxib was well tolerated in patients undergoing ECT, it did not improve related cognitive impairment.

In the end, with the aim of confirming theoretical results, with offer an example, we examine preconditioned GMRES method.

It is important to determine the prevalence of Sick Building Syndrome (SBS) symptoms in school students and teachers, which is relevant to the physical environment of the building. The aim of this study was to determine the prevalence of sick building syndrome in students and teachers of guidance schools in Babol.

This descriptive and analytical cross-sectional study was carried out in 15 guidance schools in Babol in the winter of 2018, among 150 students and 95 teachers. The MM040EA (Miljomedicine040) questionnaire was used to collect data and was completed by interview. Data were analyzed using Chi-square test.

Among the 12 symptoms of SBS, 50.7% of students had fatigue, and 44.7% had headaches. There was a significant correlation between heavy headedness (p = 0.42) and headache (p = 0.029) with students’ gender. There was a significant correlation between the teachers’ gender with the redness or dryness of facial skin (p = 0.015), redness or itching of hands (p = 0.009) and also fatigue (p = 0.003). There was a significant correlation between the symptoms of the SBS with very high temperature in the students (p = 0.050), and with the noises (p = 0.40) in the teachers.

The present study showed that more than half of the students and teachers had symptoms of SBS. Since the symptoms of SBS are associated with some physical conditions of the classroom and school environment, the health condition of the schools should be annually checked for all aspects.

Today, women’s empowerment is one of the most important challenges and concerns of the 21st century; because empowerment of women is fundamentally the process of upliftment of cultural, economic, social and political status of women, especially women who are deprived in the society. The study population was consist of rural women in Chaharmahal and Bakhtiari province that according to Krejcie and Morgan sample determination table, 384 of them were selected by stratified random sampling method. A questionnaire was used as research tools. Reliability and validity of survey instrument was evaluated. Face and content validity of the questionnaire had been confirmed by panel of experts and key informant before the pre-test stage. The reliability of instrument was assessed by conducting a pilot study among 30 samples out of the original sample. The reliability of instrument for the all sections based on Cronbach's alpha coefficients value (in the range of 0.72 to 0.94) shows acceptable level of internal consistency. Data analysis was performed by AMOS22 software. The collected data was analyzed using structural equation modeling technique. The results based on direct structural model showed that there is a positive significant relationship between variables such as women position in the family, social participation and social protection with the dependent variable of rural women’s empowerment and there is a negative significant relationship between cultural barriers with the dependent variable of rural women’s empowerment. Also, self-esteem and self-efficacy variables had a mediation role on the relationship between socio-cultural factors with rural women’s empowerment.

Nowadays one of the most important criteria for assessing the degree of development of a country is the level of women's employment. Therefore, more attention to women's employment leads to better use of this potential capacity in society. This study has been conducted with the aim of investigation factors influencing rural women's self-employment. The population of this study was including rural women in Zanjan Province that 200 of them were selected by using cluster sampling method (only 188 questionnaires were usable). A questionnaire was used to collect the data. Data analysis was performed by using SPSS20 and AMOS20 software. The collected data was analyzed using structural equation modeling multivariate technique. The results based on direct structural model with Bayesian estimation method showed that economic conditions, social conditions and education and extension courses had a significant direct effect on rural women's self-employment. Also, the result based on the mediation structural model showed that self-esteem and risk taking variables had a partial mediation on the relationship between economic conditions and social conditions with rural women's self-employment, and risk taking variable had a full mediation on the relationship between extension and educational courses with rural women's self-employment. Generally availability of economic and social conditions and conducting appropriate educational and extension programs along with strengthening individual capabilities such as self-esteem and risk-taking can be the basis for self-employment development among rural women.

One of the most important issues in educational psychology is considering the responsibility principle for growth and evolution in humans. Social responsibility is defined as a pattern of behavior, motivated by personal and social values that demonstrate an attitude of concern for the welfare of others in all levels of society where no previous personal relationship exists. The reason that the entire world is paying more attention to the subject of responsibility is because of the issues that cannot be solved only with the help of government, social organizations, or political and economic agencies; it does require extensive changes in people's lifestyle. It also seems many social problems such as delinquency, crime and community behavioral problems are associated with low levels of personal and social responsibility. In addition, many studies show that responsibility in every society leads to better adjustments in social and human relations and increasing altruism and empathy. Therefore, this study has been done with the aim of investigating factors influencing social responsibility of student.

In order to achieve the objectives of this study, data was collected from a sample of 200 students of Zanjan University and Islamic Azad University of Zanjan branch through stratified random sampling method. A questionnaire was used as research tools. The questionnaire includes three sections; 1) the individual characteristics, 2) social responsibility (designed by Lee, 2009) and, 3) factors affecting responsibility such as family, friends, peers, education, religion and media, which were measured based on the five level Likert scale. In order to conduct the study, the instrument was made by a combination of established scales from previous research and some modified scales. In the next step, reliability and validity of survey instrument was evaluated. Face and content validity were confirmed by a panel of experts and key informants before the pre-test stage. The reliability of instrument was assessed by conducting a pilot study among 30 cases out of the original sample. The reliability of the instrument for the all sections based on Cronbach’s alpha coefficients value (more than .70) shows an acceptable level of internal consistency. The SPSS software was used for descriptive analysis (including frequency, percentage and mean), and AMOS was used for inferential analyses (using structural equation modeling and multivariate technique). Based on the conceptual model, it is assumed that factor such as family, friends and peers, the educational system and media in addition to having a direct effect on the dependent variable of social responsibility, indirectly and through the mediation variable of religiosity, affect the social responsibility too.

The results based on direct structural model show that there is a positive significant relationship between variables such as family, friends and peers, the educational system and media with the dependent variable, social responsibility, and together these variables explain 57% of variances of the dependent variable. Also, based on the mediation structural model, religiosity variable has a partial mediating role in the relationship between family, friends and peers, the educational system and media with students’ social responsibility. Family, as a social institution, has an important role in encouraging the social responsibility of children, youth and even adults. The results in this study also show that there is a significant relationship between family’s and student’s social responsibility. Bandura's social learning theory (2001) which reflects on the impact of children’s behavior confirms this relationship. In this regard, it is suggested that officials organize educational programs and training sessions in order to explain the role model of parents to increase children’s responsibility.

To describe the demographic and clinical patterns of patients with uveitis referred to a tertiary center in northeastern Iran.
This cross-sectional retrospective study included 235 patients with uveitis who had been referred to the uveitis clinic of Khatam-Al-Anbia eye hospital, affiliated to Mashhad University of Medical Sciences, from February 2013 to March 2014. Data regarding patient age, sex, anatomical location of the disease, and etiologic and clinical features were analyzed.
Mean patient age at the onset of uveitis was 35.75 ± 16.3 (range: 3–82) years. The ratio of females to males was 1.5 to 1. Sixty-four percent had bilateral involvement. The predominant type of inflammation was non-granulomatous (76%). Panuveitis (46.8%, 110 cases) was the most common form of uveitis followed by anterior (37%, 87 cases), intermediate (11.9%, 28 cases), and posterior uveitis (4.25%, 10 cases). The most common diagnoses were “idiopathic” in anterior and intermediate uveitis cases, toxoplasmosis in posterior uveitis group, and Behçet and Vogt-Koyanagi-Harada diseases in panuveitis cases. Overall, noninfectious causes (80.42%) of uveitis were more frequent than infectious causes (19.57%). The proportion of noninfectious uveitis was 82.75% in anterior uveitis, 78.18% in panuveitis, 92.85% in intermediate uveitis, and 50% in posterior uveitis. The most common associated systemic disease was Behçet disease.
In contrast to most epidemiologic studies of uveitis, the clinical and etiologic patterns of uveitis were different in a tertiary referral center in northeastern Iran. Panuveitis was the most common clinical pattern in this study, and the most common associated systemic disease was Behçet disease.

Introduction and Phenol is one of the common pollutants found in many industrial effluents , which affects the environment and human health due to its special features like high toxicity and carcinogenic properties. The use of adsorbents is one of the most effective strategies for the removal of phenol. In this study, we investigated the efficiency of Citrullus colocynthis shell ash as a natural adsorbent in phenol removal from aqueous solutions.
This was an experimental study, where the effect of different variables such as the initial phenol concentrations (i.e., 10, 20, 50, 80, and 100 ppm), contact time (i.e., 2, 5, 10, and 30 min), adsorbent dose (i.e., 0.5, 1, 3, 5, 7, and 10 g/L) and pH (2-12) were studied. Then, the adsorption process was described with Freundlich and Langmuir isotherms at controlled temperatures. Excel software was used for data analysis.
The results revealed that the highest removal rate of phenol was obtained at pH of 2 (79.8%), primary phenol concentration of 20 ppm (66.4%), adsorbent dose of 5 g/l (86.8%), and contact time of 10 minutes. Also, the correlation coefficients of isotherms (Freundlich and Langmuir) showed that phenol adsorption by Citrullus colocynthis shell ash had more accordance with the Freundlich model than the Langmuir model.
We found that Citrullus colocynthis shell ash can be used as a lowcost and accessible adsorbent for phenol removal from aqueous solutions.
