Comparison of characteristics of atmospheric pressure plasma jets using argon and helium working gases

Javanmard Sara,Pouryoussefi Sohrab Gholamhosein 한국물리학회 2023 Current Applied Physics Vol.46 No.-

Dielectric Barrier Discharge (DBD) plasma jets have been studied extensively in recent years because of their wide range of applications. In this work, we studied the performance of a DBD cold atmospheric pressure plasma jet with neutral argon gas experimentally and compared the produced DBD argon plasma with the helium jet in an equivalent operation. We investigated the effect of applied voltage, flow rate, and electrodes configurations on the argon and helium plume length and analyzed the physical parameters of the plasma plume, including discharge voltage, average gas, temperatures of the discharge gap, and jet velocity in plasma-on mode via Pitot glass tube as a speedometer. The results showed that by increasing any of the applied voltage or the flow rate at low values in different electrodes arrangements, plumes shape are more homogeneous and their length increases, but the helium plasma plume is transient from laminar to turbulent flow mode at higher flow rates. The temperatures of the discharge gap between the electrodes and their surroundings in the argon jet had a large increase over the helium jet in an equi-operational. Speedometer results show that plasma discharge affects the speed of argon jet more than helium.

Mehran Javanmard,Mahdi Bayat,Alireza Ardakani 국제구조공학회 2013 Steel and Composite Structures, An International J Vol.15 No.4

In this study simply supported nonlinear Euler-Bernoulli beams resting on linear elasticfoundation and subjected to the axial loads is investigated. A new kind of analytical technique for anon-linear problem called He’s Energy Balance Method (EBM) is used to obtain the analytical solution fornon-linear vibration behavior of the problem. Analytical expressions for geometrically non-linear vibrationof Euler-Bernoulli beams resting on linear elastic foundation and subjected to the axial loads are provided. The effect of vibration amplitude on the non-linear frequency and buckling load is discussed. The variationof different parameter to the nonlinear frequency is considered completely in this study. The nonlinearvibration equation is analyzed numerically using Runge-Kutta 4th technique. Comparison of Energy BalanceMethod (EBM) with Runge-Kutta 4th leads to highly accurate solutions.

Background: Human parvovirus B19 (B19V) is one of the smallest DNA viruses and shows great resist-ance to most disinfectants. Therefore, it is one of the common contaminant pathogens present in blood and plasma products. Parvovirus 4 (PARV4) is a newly identified parvovi-rus, which is also prevalent in parenteral transmission. In this study, we aimed to evaluate the prevalence of B19V and PARV4 DNA among patients with hemophilia in Birjand County in eastern Iran. Methods: This was a cross-sectional epidemiological study comprising nearly all people with hemo-philia in this region. Whole blood samples were taken after patient registration and sent for plasma isolation. After nucleic acid extraction, B19V was detected with real-time poly-merase chain reaction, PARV4 DNA was then detected using sensitive semi-nested PCR. Results: In total, there were 86 patients with hemophilia, with mean age 28.5±1.5 years. Of these, 90.7% were men and 9.3% women; 84.9% had hemophilia A and 7.0% had hemophilia B. We found 11 patients (12.8%) were positive for B19V DNA and 8 were positive (9.3%) for PARV4 DNA. The prevalence of B19V was higher in middle-aged groups rather than younger people, whereas PARV4 infection was more common in younger patients (P<0.05). Conclusion: There was a high prevalence of B19V and PARV4 infection in this high-risk group of pa-tients with hemophilia. Due to the clinical significance of the B19 virus, imposing more precautionary measures for serum and blood products is recommended.

( Kamal Javanmard ),( Hamideh Namdar Mohammadi ) 세계문화관광학회 2016 International Journal of Culture and tourism Resea Vol.9 No.1

Media is a unique world in history of human civilization. There has never been such a fast change within history of human life because technology of communications not only has changed the world into a small village but also modernity waves have destroyed structures of societies and have created new insights and dimensions. In this direction, change of life style is considered as one of main indices of modernity. Life style forms personal identity, personality, attitude and approaches. The main objective of the present research is to recognize the effect and function of satellite channels on life styles of female students of Letters faculty of Islamic Azad University of Kerman. After testing hypotheses, it was found that there is a significant relationship between watching a Persian language satellite channel (GEM) and precocious puberty, kind of dressing, fidelity to beliefs, traditions and values. Also this channel affects considerably life style, identity and socio-cultural capital of students.

Habibollah Javanmard,Hoda Hasani 한국유통과학회 2017 The Journal of Industrial Distribution & Business( Vol.8 No.1

Purpose – Market orientation is a key factor for business performance in today’s fluctuating conditions. This study investigates whether the employment of innovation can improve the innovative capability and increase the performance by gaining competitive advantages or not. Therefore, this study aims to investigate the effects of market orientation on the performance of small and medium size distributer enterprises (SMDEs) in Iran. Research design, data, and methodology – Customer orientation, Competitor orientation, and Inter-functional coordination have been regarded as market orientation indices to determine the effects of these indices on marketing innovation, gaining competitive advantages, and companies’ performance as well. Data were collected from managers and experts in SMDEs in Iran. The structural equations modeling are used for analysis. Results – The results indicated that marketing innovation has been improved in competitive companies that enjoyed a high level of Inter-functional coordination among the various units. Besides, marketing innovation resulted in gaining competitive advantages regarding cost management, concentration, and differentiation in these companies. In addition, it was observed that SMDEs that obtain competitive advantages are equipped to reap superior performance. Conclusions – With cost management, differentiation and concentration are more likely to enhance the enterprise efficiency and effectiveness than other companies. Additionally, competitiveness, inter-functional coordination, and marketing innovation in SMDEs have a positive impact on marketing innovation.

Arsalan Kazemi,Habibollah Javanmard,Ramona Mohammadi 한국유통과학회 2017 Asian Journal of Business Environment (AJBE) Vol.7 No.1

Purpose - In order to achieve the organizational objectives, the behavior of the employees and their collaboration with management should be taken into account. It has been shown that strategic behavior depends on a number of different factors. The aim of this article was determining the relationship between factors related to the strategic behavior. Research design, data, and methodology - Accordingly, a conceptual model was developed and tested in the form of a survey. Participants of the study were the employees working in the social Insurance company of Tehran. Data was collected using a questionnaire conducted among managers and the staff. A correlation model was used for data analysis by employing the SPSS software. Results - The findings showed there was a relationship between employees’ engagement and the strategic behavior. Conclusions - Our research has demonstrated the effect of employees’ engagement on the strategic-driven behavior, emphasizing the role of employees’ engagement in health-care service firms. Although previous service research has focused on the factors that drive employees’ performance, it seems that most of this research has been inspired by the idea of the service profit chain, focusing on the effect of employees’ satisfaction on performance.
