Background: The accurate results of the individual doses in personal dosimety which are reported by the service providers in personal dosimetry are very important. There are national / international criteria for acceptable dosimetry system performance.Objective: In this research, the sources of uncertainties are identified, measured and calculated in a personal dosimetry system by TLD.Method: T...

SUMMARY In a continuing search for unique karyotypic changes in human leukemia and cancer, investigators have encoun tered a number of patients in whom partial trisomy and longitudinal duplication of some chromosomal regions, both involving especially the long arm of Chromosome 1, and isochromosomes were present. These abnormalities were also observed by us in human phytohemagglutinin stimulate...

SUMMARY An exceptional Burkitt lymphoma patient, a 16-year-old boy, yielded tumor biopsy cells and derived tissue culture lines that displayed a strong surface accumulation of IgM heavy and kappa light chain specificities judged by direct membrane fluorescence and cytotoxicity tests. This property was main tained unchanged in the course of more than 5 months of serial passage in vitro. A fourth...

In 1954 army historian George Stanley claimed that naval initiatives from the eighteenth century to 1870s by French and British armies in Canada local land militia were true roots of Royal Canadian Navy. He privately admitted he was being intentionally provocative. The present article, however, reviews subsequent scholarship offers new research strengthens Stanley’s findings, shows continued pr...

In a paper in this issue, Rief et al. [1] present a new scale for assessing illness behaviour. The Scale of the Assessment of Illness Behaviour (SAIB) comprises five dimensions: verification of diagnosis, expression of symptoms, medication reliance, illness consequences and bodily scanning. The initial validation of the scale has been completed through comparison of patients presenting with une...

Various normwise relative condition numbers that measure the sensitivity of Bott– Duffin inverse and the solution of constrained linear systems are characterized. The sensitivity of condition number itself is then investigated. Finally, upper bounds are derived for the sensitivity of componentwise condition numbers. 2002 Elsevier Science Inc.

Various normwise relative condition numbers that measure the sensitivity of matrix inversion and the solution of linear systems are characterized. New results are derived for the cases where two common, noninduced matrix norms are used, and where different vector norms are used for the domain and range of the matrix. Condition numbers that respect the structure of symmetric problems are also an...
