    Computations of drops collisions, coalescence, and other problems involving drops are presented. The computations are made possible by a finite difference/front tracking technique that allows direct solutions of the Navier-Stokes equations for a multi-fluid system with complex, unsteady internal boundaries. This method has been used to examine the various collision modes for binary collisions of drops of equal size, mixing of two drops of unequal size, behavior of a suspension of drops in linear and parabolic shear flows, and the thermal migration of several drops. The key results from these simulations are reviewed. Extensions of the method to phase change problems and preliminary results for boiling are also shown

    The properties of the pinecone, an Iranian natural and low cost agricultural by-product, have been studied for its potential use in textile dyeing. In this research, wool fibres due to their high affinity towards the aqueous extract of natural dyes have been used and their dyeability with powdered pinecone is studied. The effects of two different variables, including dye concentration and mordant type on the color properties of dyed wool fibres are investigated. To determine the functional group of pinecone colorant, FTIR test is also performed. The colorimetric properties (color strength, color difference, color coordinates CIE Lab) and the color fastness (wash and light) results are considered for quantifying evaluation of dye concentration and mordant type effects. The results show that the wool possesses high affinity towards pinecone dyeing solution, and the used mordant methods exhibit different shades ranging from beige to brown with good fastness

    Impact of ethnocentrism on interethnic interactions among local students in Malaysian universities

    Get PDF
    In this study, the authors examine the influence of ethnocentrism on offline and online interethnic interactions among Malaysian students at two multiethnic and multicultural Malaysian public universities. The responses of 200 Malay, 105 Chinese, and 38 Indian undergraduate students were analysed. Results reveal a significant difference between the level of offline and online interethnic interactions among respondents. It was found that students had more offline interethnic interactions compared to online interactions. This is due to the fact that interactions through online media are more dependent on a conscious choice and decision to communicate actively and to take the step for interethnic communication. Thus in situations where they could choose whether or not to interact, they presumably willingly elected to not take that step. It can be concluded that students were uninterested in making any effort in expanding their interethnic interaction in the virtual world beyond their own ethnic group due to their ethnocentric attitudes. Therefore, all hypotheses of this study were accepted

    Intra-oral low level laser therapy in chronic maxillary sinusitis: a new and effective recommended technique

    Get PDF
    Background: Chronic sinusitis is one of the most common chronic diseases involving different age groups. Because the nature and etiology of chronic sinusitis are not completely known, there is not any standard treatment for this disease. It has been suggested that low-level laser can be used in treating chronic sinusitis but there are limited studies about its usage. In this research, intra-oral radiation of low-level laser has been described and implemented for the first time. Suggested hypotheses about the efficacy of this type of radiation (intra-oral) in treating chronic maxillary sinusitis includes this fact that the depth of maxilla’s vestibule is also the floor of maxillary sinus and sinus discharges collect in this area because of gravity effect. Therefore, with considering suitable radiation angle, this area gets the most benefits of laser’s anti-inflammatory effects. Material and Methods: In this study, 20 patients with chronic maxillary sinusitis were included. They were assessed before and after treatment. Treatment plan was performed in 8 sessions every other days using low-level diode laser with 810 nm. Snot-22 questionnaire and rhinomanometry were used for evaluating patients. Changes of signs and symptoms were recorded in questionnaire every session and 6 months after treatment. Friedman and Wilcoxon tests were used for data analyses. In this study, P value < 0.05 was considered statistically significant. Results: All variables and all symptoms of patients were improved using intra-oral low-level laser and this improvement was statistically significant ( P value<0.05). There was also significant decrease in nasal airway resistance and significant increase in air flow ( P value<0.05). Six month after treatment completion, there was no significant difference between the results of completion and the results of 8th treatment session ( P value< 0.05). Conclusions: Using intra-oral low-level laser is a suitable way to treat patients with chronic maxillary sinusitis

    Competency Ddevelopment Strategies of Gglobal Transformational Lleadership in Iran’s Ministry of Energy

    Abstract Global Transformational Leadership (GTL) is an approach that focuses on understanding, adopting and directing change by creating a global network and teamwork and learning environment in order to compete in the global arena. The GTL has attracted the attention of organizations that operate globally, but there are uncertainties regarding its various dimensions, especially the strategies for developing its competencies in organizational leaders. Iran's Ministry of Energy (IME), as a vital government agency, has a global orientation, but is facing challenges to develop its leaders in an increasingly competitive global marketplace. Thus, this research aims to explore strategies for developing GTL competencies in the context of IME. The research method is qualitative with an exploratory approach. The study population is managers with experience and expertise in the international projects of IME. To collect data, 15 of these managers were selected using the purposeful sampling method and participated in semi-structured interviews. The thematic method was used to analyze the collected data. The findings led to identifying strategies to develop transformative leadership competencies in IME. Two overarching strategies identified, namely empowerment strategies and individual development strategies are discussed and their implications for IME are highlighted.Introduction Today, the stated goals and missions of many organizations oriented toward global markets with emphasis on continuous interactions with foreign suppliers, partners, employees, shareholders and customers. The global environment, along with the transformation that has created in the competitive landscape of businesses, has changed the approach of directing organizations and developing the competencies leaders need to be successful globally. Thus, it is expected that the global leaders are equipped with the new knowledge, skills and attitudes which enable them to effectively guide organizations in a complex, changing and often ambiguous global environment. Given the reality of today’s global markets, it is argued that organizations should revisit and reassess their leadership development strategy and focus on developing their leaders' competencies that meet their existing requirements in the face of global competitive forces. To meet this challenge, a key decision for all organizations is choosing the right strategies for developing leaders’ competencies. The main purpose of this article is to present strategies for the development of global transformative leadership competencies in IME based on the views of its experts and managers with international experience.Case studiesThis research is carried out in Iran’s Ministry of Energy and its affiliated companies that operate offshores.Materials and methodsThis research uses qualitative method and collect its data through semi-structured interviews. The theme analysis method was used to identify strategies for developing GTL competencies.The data collected in semi-structured interviews from 15 experts and senior managers of IME, who hold senior positions, such as deputies and advisors to the minister and CEOs of international companies affiliated with the Ministry of Energy, with relevant work experience in international projects.Results and discussions The analysis of the themes in interviews led to the identification of 123 concepts were identified. After allocation of these concepts to themes and refining them several times, 56 basic themes, six organizing themes and two overarching themes were obtained. The findings revealed that although IME bears responsibility for developmental strategies that aim to equip leaders with necessary competencies, but the onus of the competence development strategies primarily rests on individual leaders themselves. In other words, it is argued that individual strategies are complementary to organizational strategies in leadership competency development.ConclusionsThe findings of the research highlight the critical role of empowerment and individual development strategies for developing GTL competencies. The empowerment strategies include professional development, knowledge enhancement, provision of opportunities for cross boarder presence and experience, and granting authority. The individual development strategies, on the other hand, are consist of reflective learning approaches, self-learning and independent study, and revision and reshaping of leader’s mentality

    Comparison of analgesic effects of intravenous and intranasal ketorolac in patients with mandibular fracture-A Randomized Clinical Trial

    Get PDF
    Similarity of pharmacokinetics of intranasal ketorolac to the intravenous form and other advantages have promoted its application. This study compared the analgesic effects of intravenous and intranasal ketorolac in patients undergoing mandibular fracture surgery. In this clinical trial study, Sixty-four patients with unilateral mandibular fracture were divided randomly into two groups. In group 1, 30 mg of intravenous (IV) ketorolac was injected every 8 hours and in group 2, intranasal (IN) ketorolac spray was used as a 100-µL puff in each nostril (31.5 mg) every 6 hours. After each patient regained consciousness, pain intensity was measured based on visual analogue scale for 48 hours. Finally, the total dose of the opioid analgesic agent (pethidine) and the time for the first request for an analgesic agent were recorded for each patient, and their means were compared in each group with proper statistical tests. Mean pain intensity of patients at baseline was significantly higher than that at other intervals and then, it decreased significantly (P0.05). Application of intranasal ketorolac spray decreased pain after mandibular fracture surgery, especially at 8-hour interval after surgery, decreasing the need for opioids

    The increasing resistance to macrolide, lincosamide, and streptogramin B agents among methicillin-resistant Staphylococcus aureus (MRSA) is a worldwide problem for the health community. This study aimed to investigate the prevalence of ermA, ermB, ermC, and msrA in MRSA strains isolated from burn patients in Ahvaz, southwest of Iran. A total of 76 isolates of S. aureus were collected from January to May 2017 from Taleghani Burn Hospital in Ahvaz. Among 76 S. aureus strains collected, 60 (78.9%) isolates were MRSA. The antimicrobial susceptibility testing for MRSA showed extreme high resistance rate to clarithromycin (100%) and azithromycin (100%), followed by erythromycin (98.3%). The PCR assay revealed that the frequency rates of msrA, ermA, and ermC genes were 23 (38.3%), 28 (46.7%), and 22 (36.7%), respectively. In addition, none of the MRSA isolates had the ermB gene. Because of the high prevalence of macrolide and lincosamide resistance found in MRSA isolates from infections of burn patients in Ahvaz, southwest of Iran, it is recommended that local periodic survey be performed for controlling the dissemination of antimicrobial resistance
