Investigation of 50 Hz Pulsed DC Nitrogen Plasma with Active Screen Cage by Trace Rare Gas Optical Emission Spectroscopy

Plasma Science and Technology 2014年第4期16卷 324-328页

作者： A.SAEED A.W.KHAN M.SHAFIQ F.JAN M.ABRAR M.ZAKA-ul-ISLAM M.ZAKAulLAH Department of Physics Gomal University Department of Physics Quaid-i-Azam University Department of Physics Hazara University Mansehra Plasmant Department of Chemistry Univesity of Antwerp campus DriEkin

Optical emission spectroscopy is used to investigate the nitrogen-hydrogen with trace rare gas （4% Ar） plasma generated by 50 Hz pulsed DC discharges. The filling pressure varies from 1 mbar to 5 mbar and the current density ranges from 1 mA-cm-2 to 4 ***-2. The hydrogen concentration in the mixture plasma varies from 0% to 80%, with the objective of identifying the optimum pressure, current density and hydrogen concentration for active species （[N] and IN2]） generation. It is observed that in an N2-H2 gas mixture, the concentration of N atom density decreases with filling pressure and increases with current density, with other parameters of the discharge kept unchanged. The maximum concentrations of active species were found for 40% H2 in the mixture at 3 mbar pressure and current density of 4 ***-2.

Asian Pacific Journal of Tropical Medicine 2018年第4期11卷 292-296页

Objective: To discover the mechanism behind ameliorative effects of Michelia champaca(M. champaca) in gastrointestinal, respiratory and cardiovascular disorders. Methods: Antispasmodic potential was evaluated by trying the M. champaca extract(aqueous:ethanolic) on rabbit aorta, trachea and jejunum in vitro. Isotonic and isometric transducers coupled with Power Lab data acquisition system was used to record the responses of isolated tissues. Results: M. champaca extract relaxed the spontaneous and high K^+(80 mmol/L)-induced contractions of isolated jejunum preparation of rabbit showing a Ca^(2+) channel blocking mechanism. Moreover, extract shifted calcium concentration response curves towards right like standard calcium channel blocker verapamil. In rabbit tracheal preparation, M. champaca relaxed both carbachol(1 μmol/L) and high K^+-induced contractions, likewise verapamil. In rabbit aorta preparation, M. champaca relaxed phenylephrine(1 μmol/L) and high K^+-induced contractions similar to verapamil. Conclusion: M. champaca possesses spasmolytic, airways relaxant and vasodilator actions mediated perhaps due to blocking of Ca^(2+) channels, hence validating its therapeutic usage in diarrhea, asthma and hypertension.

An Improved Framework for Requirement Change Management in Global Software Development

引用

Journal of Software Engineering and Applications 2014年第9期7卷 779-790页

作者： Nasir Mehmood Minhas Qurat-ul-Ain Zafar-ul-Islam Atika Zulfiqar University Institute of Information Technology PMAS Arid Agriculture University Rawalpindi Pakistan

In this research, an improved framework for requirement change management in global software development (RCM_GSD) has been presented. The objective is to manage the change in requirement specifically in global software development in an appropriate manner. The proposed frame-work RCM_GSD follows the required processes of RCM and reduces the concerns of GSD. Systematic Literature Review (SLR) was conducted for exploration of relevant research. During literature study, it is analyzed that the existing techniques of change management were not suitable for global software development (GSD). The change in requirements becomes more complicated in distributed environment due to the lack of communication and collaboration among globally dispersed stakeholders. The proposed model is compared with other models proposed in recent literature and analysis is made between them;feedback was obtained from the domain experts as well. The feedback and comparison results show that the proposed model provides an appropriate solution for requirement change management in GSD.
