Analysis of Power in an Argon Filled Pulsed Dielectric Barrier Discharge

引用

Plasma Science and Technology 2013年第7期15卷 635-639页

作者： U.N.PAL pooja GULATI Ram PRAKASH Mahesh KUMAR v.SRIvASTAvA S.KONAR Microwave Tubes Division CSIR-Central Electronics Engineering Research Institute (CSIR-CEERI)Pilani Rajasthan-333031 India Birla Institute of Technology (BIT) Mesra Ranchi Jharkhand-835215 India

In this paper an argon filled coaxial dielectric barrier discharge （DBD） has been studied to understand the detail of power transfer from a unipolar square pulse to plasma during discharge. A dielectric barrier discharge based diffuse pulse discharge and its electrical charac-teristics are investigated. A quartz coaxial DBD tube filled at different pressures is used in the experiment. A unipolar pulse voltage of different peak voltages and frequencies has been applied to the discharge electrodes for the generation of microdischarges. Two current pulses are used for two consecutive discharges per applied voltage pulse. The second discharge, which occurs at the falling flank of the voltage pulse, is induced by the charges stored on the dielectric barrier during the first discharge. It has been deduced that the power supplied to ignite the first discharge is partly stored to ignite the second discharge when the applied voltage decays. This process ul- timately leads to much improved power transfer to the plasma. The knowledge obtained from dynamic processes of the DBDs in the discharge gap explains quantitatively the mechanism of ignition, development and extinction of the DBDs.

Development and validation of an HPLC-Uv method for analysis of methylphenidate hydrochloride and loxapine succinate in an activated carbon disposal system

引用

Journal of Pharmaceutical Analysis 2018年第6期8卷 349-356页

Unused medications have the possibility of being abused, causing serious harm to individuals who were not prescribed the drug. The Food and Drug Administration(FDA) recommends the proper disposal of unused prescribed medications to maintain safety and prevent environmental hazards. However, many of the current disposal techniques do not properly address safety. A drug disposal pouch containing granular activated carbon offers a unique disposal method to deactivate residual or expired medication in a convenient, effective, and safe manner. A robust and validated method for methylphenidate hydrochloride and loxapine succinate was developed using high-performance liquid chromatography(HPLC) and the deactivation efficiency of the disposal system was tested. Methylphenidate hydrochloride was analyzed on a C18 analytical column(250 mm ?4.60 mm, 100?) using acetonitrile-water(0.05%(v/v) trifluoroacetic acid) as the mobile phase at a flow rate of1.0 mL/min with a run time of 15 min and retention time of 7.8 min. Loxapine succinate was separated on a C8100?(250 mm ? 4.6 mm, 5 mm) column maintained at 25 °C using a flow rate of 1.0 mL/min. The run time was 10 min and the retention time of the drug was around 4.6 min. Mobile phase was composed of acetonitrile and water(0.3% triethylamine) at pH 3.0 as 40:60(v/v). Reference standard solutions(100 mg/mL) for both drugs were prepared by dissolving in mobile phases. These methods provide good linearity(R2? 0.999) over the range of 5–100 mg/mL for methylphenidate hydrochloride and 0.1–100 mg/mL for loxapine succinate. The assay methods were successfully applied to study the deactivation of these drugs.

列奥纳多·达·芬奇(Leonardo da vinci),你很难说他属于哪个时代。他生活在500多年前,但一直以来,他经常被很多人当做卖点来提起,直到21世纪。这是因为他和他同时代的米开朗基罗(Michelangelo)、拉斐尔(Raffael)、桑德罗·波提切利(Sandro Botticelli)不同。他们是传统的守护神,而列奥纳多则是进步的英雄,是为绝对艺术的万神庙创造大师级作品的创造者和做着工业时代的机器梦的人。更值得称颂的是,他一方面用做研究的手冷静地解剖尸体,呼吸着它的恶臭;另一方面却在他的画作中展示了超越人世间生活视角的享受、美感和永恒。

Objective:To conduct a comparative analysis of the vP4 gene sequences of Indian wild type (06361,0613158,061060 and 0715880) and cell culture adapted(06361-CA,0613158-CA.061060- CA and 0715880-CA) G1P[8]rotavirus ***:Full-length vP4 genes of each of the four wild type G1P[8]rotavirus strains and their cell culture adapted counterparts displaying consistent cytopathic effect were subjected to RT-PCR amplification and nucleotide sequencing. Results:All four cell culture adapted G1P[8]rotavirus strains showed nucleotide and amino acid substitutions in the vP4 gene as compared to their wild type *** number of substitutions however,varied from 1-64 and 1-13 *** substitutions were distributed in both vP5* and vP8* subunits of vP4 gene respectively of permeabilizalion and hemagglutinaling activity. The presence of unique amino acid substitutions was identified in two of the four wild type(v377G. S387N in 061060 and 1644L in 0715880) and all four cell culture adapted(A46v in 0613158-CA. T60R in 06361-CA,L237v.G389v and Q480H in 061060-CA and S615G and T625P in 0715880-CA) strains for the first time in the vP4 gene of P[8]*** acid substitutions generated increase in the hydrophilicity in the cell culture adapted rotavirus strains as compared to their corresponding wild type ***:Amino acid substitutions detected in the vP4 genes of G1P[8]rotavirus strains from this study together with those from other studies highlight occurrence of only strain and/or host specific substitutions during cell culture adaptation. Further evaluation of such substitutions for their role in attenuation,immunogenicity and conformation is needed for the development of newer rolavirus vaccines.

Performance Comparison of PIN and APD based FSO Satellite Systems for various Pulse Modulation Schemes in Atmospheric Turbulence

引用

Communications and Network 2013年第3期5卷 200-203页

作者： pooja Gopal v. K. Jain Subrat Kar Bharti School of Telecom Tech. and Mgmt. IIT Delhi New Delhi India Electrical Engineering Dept. IIT Delhi New Delhi India

In this paper, the performance of various Pulse Position Modulation (PPM) schemes has been analysed for PIN and APD receivers in the presence of atmospheric turbulence. It is observed that the performance of the APD receiver is always better than that of the PIN receiver as expected. Among the various modulation schemes, the performance of Differential Amplitude PPM (DAPPM) scheme with more number of amplitude levels is better than that of the other schemes for the same single level peak amplitude. Further, the optimum gain of APD receiver does not change substantially for different modulation schemes and turbulent conditions.
