Maps of GPS phase scintillation at high latitudes have been constructed after the first two years of operation of the Canadian High Arctic Ionospheric Network (CHAIN) during the 2008–2009 solar minimum. CHAIN consists of ten dual-frequency receivers, configured to measure amplitude and phase scintillation from L1 GPS signals and ionospheric total electron content (TEC) from L1 and L2 GPS signal...

Note further that (1.1) or (1.2) above guarantees the existence of a ball in U with 'error' very large as compared to that of boxes in U with sides parallel to the axes. We recall that in 1954 ...

In this paper a description is presented in which the architectural, lexical and mapping differences are foregrounded between two compositional systems, both operating in the health care domain: LinkBase® and SNOMED. Based on these distinctive features, repercussions on NLP applications are exemplified and briefly discussed.

The aim of this study is to evaluate the effect of meat content and surface smoothness on the deactivation of Listeria monocytogenes in beef-agar food models achieved by shortwave ultraviolet (UVC) light. Food models with various meat contents were made using chopped beef slices and agar solution. Prepared models together with a Listeria selective agar (LSA) plate and a slice of cooked beef wer...

Shape and size of the nucleus, coupled with changes in chromatin amount and distribution, still remain the basic microscopic criteria for cytological diagnoses. Diagnostic recognition of the nuclear shape in pathological histology and cytology has been always based on the assumption that it is the content in nucleic acids, which determines the nuclear shape. The present review challenges this o...
