In a transcription system using a HeLa cell mitochondrial lysate programmed by mitochondrial DNA constructs containing the main heavy strand promoter and the transcription termination site at the 16S rRNA/leucyl-tRNA boundary, an appreciable fraction of the heavy strand transcripts terminates at this site, as it does in vivo. A DNA binding protein(s) that(More)
BACKGROUND The aim of this study of native pig mandibles was to investigate the accuracy and quality of the representation of peri-implant defects by intraoral radiography (IR), panoramic radiography (PR), computer tomography (CT), and digital volume tomography (DVT). METHODS The examination was carried out on 19 native pig mandibles. In the toothless(More)
Light scattering, or the so-called Yule-Nielsen effect, and ink penetration into the substrate paper play important roles in tone reproduction. We develop a framework in which the influences of both of these effects on the reflectance and tristimulus values of a halftone sample are investigated. The properties of the paper and the ink and their bilateral(More)
The use of spectrophotometers for color measurements on printed substrates is widely spread among paper producers as well as within the printing industry. Spectrophotometer measurements are precise, but timeconsuming procedures and faster methods are desirable. The rapid development of digital cameras has opened the possibility to use consumer digital(More)
Using a statistical analysis of light propagation in media, we propose a revision to Kubelka-Munk (K-M) theory by taking into account the effect of scattering on the path length of light propagation (path variation). This leads to new relationships between the K-M scattering S and absorbing K coefficients and the intrinsic scattering s and absorbing a(More)
