Determination of Scanning Efficiencies in Experiments Using Nuclear Emulsion Sheets
نویسنده
چکیده
During their exposure, nuclear emulsion sheets detect both tracks from experimentrelated particles, as well as a considerable amount of background tracks, mainly due to cosmic rays. Unless the exposure has been fairly short, it is therefore fairly likely that a fraction of the tracks that have been identified as belonging to the particles the experiment is interested in, are really due to background. A method, which allows to measure this fraction reliably directly from the data, is described.

Fabrication and in vitro evaluation of Ketotifen Fumarate-loaded PLGA nanoparticles as a sustained delivery system
Abstract Ketotifen fumarate is a non-bronchodilator anti-asthmatic drug which inhibits the effects of certain endogenous substances known to be inflammatory mediators, and thereby exerts antiallergic activity. The present study describes the formulation of a sustained release nanoparticle (NP) drug delivery system containing ketotifen, using poly (D,L lactide-co-glycolide acid) (PLGA). Biodegra...

متن کاملFast automated scanning of OPERA emulsion films
The use of nuclear emulsions to record tracks of charged particles with an accuracy of better than 1 micron is possible in large physics experiments thanks to the recent improvements in the industrial production of emulsions and to the development of fast automated microscopes. The European Scanning System (ESS) is a fast automatic system developed for the mass scanning of the emulsions of the ...
