In January 2007 the CERN director general announced the plan for the staged upgrade of the LHC luminosity. The plan foresees a phase 1 upgrade reaching a peak luminosity of 3 × 10 cms followed by phase reaching up to 10 cms. We discuss the physics potential and the experimental challenges of an upgraded LHC running. The detector R&D needed to operate ATLAS and CMS in a very high radiation envir...

in this study, caffeic acid (ca) and its three derivatives including 3-caffeoylquinic acid (3-cqa, neochlorogenic acid), 4-caffeoylquinic acid (4-cqa, cryptochlorogenic acid), and 5-caffeoylquinic acid (5-cqa, chlorogenic acid) were identified in bupleurum chinense aerial parts using reverse-phase high-performance liquid chromatography (rp-hplc) with photodiode array (pda) detector, reference c...

INTRODUCTION.The RATIO DETECTOR uses a double-tuned transformer to convert the instantaneous frequency variations of the fm input signal to instantaneous amplitude.AM version is shown at A to make it a CWSSB receiver, change the detector to a. 4An FM ratio detector of the type mentioned in the text. It is similar to the.Ratio detector or discriminator was widely used for FM demodulation within ...

This paper presents a single-stage Vernier Time-to-Digital Converter (VTDC) that utilizes the dynamic-logic phase detector. The zero dead-zone characteristic of this phase detector allows for the single-stage VTDC to deliver sub-gate delay time resolution. The single-stage VTDC has been designed in 0.13 μm CMOS technology. The simulation results demonstrate a linear input-output characteristic ...

The present study was designed to develop a simple, validated liquid chromatographic method for the analysis of azithromycin in bulk and pharmaceutical dosage forms using ultraviolet detector. The best stationary phase was determined as C18 column, 5 μm, 250 mm × 4.6 mm. Mobile phase was optimized to obtain a fast and selective separation of the drug. Flow rate was 1.5 mL/min, Wavelength was se...
