POSITIVE AND NEGATIVE ION MASS SPECTRA OF RING - SUBSTITUTED NITROBENZENES
The 70 ev positive and negative ion mass spectra of ring-substituted nitrobenzenes were studied. The influence of the substituent group on the fragmentation modes of the molecular ions is discussed. The effect of pressure in the formation of negative ions was also studied. As expected, the ratio of fragment ions to negative molecular ions decreased with increasing pressure in ion source.
متن کاملDigital Memory: The Visual Recording of Mass Grave Exhumations in Contemporary Spain
Exhumations of the victims of Franco's repressive policies are cultural practices of tremendous heuristic value and allow for the analysis of the public emergence, circulation and consumption of traumatic memory in local contexts. The use of visual media to capture social action in the surroundings of the exhumations serves as both a recording and as a triggering device for this emerging social...
متن کاملThe Invariant Mass Spectra Profile
Two possible reasons for the narrow peak observation in the invariant mass spectrum of the pK 0 s close to 1.54 GeV/c 2 are discussed.
متن کاملDigital recording and numerical reconstruction of holograms
This article describes the principles and major applications of digital recording and numerical reconstruction of holograms (digital holography). Digital holography became feasible since charged coupled devices (CCDs) with suitable numbers and sizes of pixels and computers with sufficient speed became available. The Fresnel or Fourier holograms are recorded directly by the CCD and stored digita...
متن کاملDigital recording of aboriginal rock art
A technique to digitally document and thereby permanently preserve prehistoric rock art has been developed. Laser scanning and texture mapping from digital images were used. Methods involving texture mapping require the exact relationships between the image and geometrical sensors. For geological structures, such as caves, the distinctive features required for registering the texture with the g...
