background: in this study, measurement of indoor radon and its progeny levels was carried out in gas turbine power station in haryana ( india ), where natural gas is used as fuel. for comparison, the results of a study carried out in thermal power plant in haryana are also presented. radon being a ubiquitous air pollutant has global impact and its monitoring in the environment at work places is...

In view of the fact that the radon progeny contribute the highest to the natural radiation dose to general populations, large scale and long-term measurements of radon and its progeny in the houses have been receiving considerable attention. Solid State Nuclear Track Detector (SSNTD) based systems, being the best suited for large scale passive monitoring, have been widely used for the radon gas...

TACTIC is a new detector for low energy nuclear reactions currently under development at TRIUMF. The cylindrical ionization chamber allows three-dimensional reconstruction of particle tracks by means of a two-dimensional anode array combined with a TOF measurement of the drift electrons. In addition, the integrated charge for each pulse provides information about the energy loss of the particle...

Use of in situ hybridization optimized for fluorescent detection of nuclear RNA has revealed a striking localization of specific viral RNAs within nuclei of cells latently infected with EBV. Several hundred kb of specific transcripts is sharply restricted to a small region of the nucleus, frequently in a curvilinear "track". Detection of nuclear RNA was evidenced by hybridization without denatu...

The deterioration of railway tracks raises great concerns about the integrity of assessments and evaluations of railway tracks currently in service. Integrated inspection strategies coupled with innovations in inspection technology can lead to significant improvements in operational cost efficiency and reliability without the requirement of a fundamental shift in the existing understanding o...

Object correlation and maneuver detection are persistent problems in space surveillance and space object catalog maintenance. This paper demonstrates the utility of using quadratic trajectory control cost, an analog to the trajectory L2-norm in control, as a distance metric with which to both correlate object tracks and detect maneuvers using Uncorrelated Tracks (UCTs), real-time sensor measure...

Abstract We have carried out muon spin relaxation and rotation measurements on the newly discovered kagome metal KV 3 Sb 5 , find a local field dominated by weak magnetic disorder which we associate with nuclear moments present, modest temperature dependence tracks bulk susceptibility. no evidence for existence of V 4+ moments, suggesting that physics underlying recently reported giant unconven...
