The National Physical Laboratory, Queens Road, Teddington, Middlesex, TWll OLW, United Kingdom An intercomparison of radiance temperature scales lias been performed by the National Physical Laboratory (NPL) and the National Institute of Standards and Technology (NIST) using a standard transfer pyrometer operating at a wavelength of approximately 1000 nm. It was found that the radiance temperatu...

Ultrasonic scalers are used in dentistry to remove calculus and other contaminants from teeth. One mechanism which may assist in the cleaning is cavitation generated in cooling water around the scaler. The vibratory motion of three designs of scaler tip in a water bath has been characterised by laser vibrometry, and compared with the spatial distribution of cavitation around the scaler tips obs...

This study analyzes the link between non-performing loans (NPL) and bank concentrations in Turkey using wavelet coherence approach. In line with expectation of present study, there were fluctuations NPL by 5 7 banking 2000 2003. Moreover, ratios long term cause concentrations. It is concluded that Turkish sector active on size asset concentration largest banks. Additionally, a positive correlat...

Bank Mandiri (Persero) Tbk yang terdaftar di Bursa Efek Indonesia periode tahun 2013-2021. menggunakan pendekatan kuantitatif desain penelitian analisis regresi linier berga...

− The kilogram is unique among the base SI units in being the only one defined by an artefact. A major problem with maintaining the traceability of the mass scale is the inherent instability of the kilogram artefacts. To resolve the problem, there had been done a comparison of the values of the national standard kilogram of 18 European National Metrology Institutes (NMIs) by National Physical L...

A new score statistic is derived, which uses information from registries (age-specific incidences) and family studies (sib-sib marginal correlation) to weight affected sibling pairs according to their age at onset. Age at onset of sibling pairs is modelled by a gamma frailty model. From this model we derive a bivariate survival function, which depends on the marginal survival and on the margina...
