Scaling Hemodialysis Target Dose to Reflect Body Surface Area, Metabolic Activity, and Protein Catabolic Rate : A Prospective, Cross-sectional Study
(2017-03-01)BACKGROUND: Women and small men treated by hemodialysis (HD) have reduced survival. This may be due to use of total-body water (V) as the normalizing factor for dialysis dosing. In this study, we explored the equivalent ... -
Scaling relations between numerical simulations and physical systems they represent
(2012-04)The dynamical equations describing the evolution of a physical system generally have a freedom in the choice of units, where different choices correspond to different physical systems that are described by the same equations. ... -
Scaling the mobility of health workers in an enlarged Europe : An open political-economy perspective
(2016-10-01)The enlargement of the European Union in 2004 and 2007 and the marketisation of health care are increasing the mobility of workers and driving a scalar transformation of the sector across Europe. Drawing on questionnaires ... -
Scaling up wiki-based blended learning environment
(ICIE, 2009)Since their introduction in the mid nineties, the use of wikis in education has been extensively studied (Bruns & Humphreys, 2007; Forte & Bruckman, 2007; Mindel & Verma 2006; Richardson 2006), debated and documented (see ... -
SCALS: a fourth-generation study of assisted living technologies in their organisational, social, political and policy context
(2016-02-01)Introduction: Research to date into assisted living technologies broadly consists of 3 generations: technical design, experimental trials and qualitative studies of the patient experience. We describe a fourth-generation ... -
SCAMPS : the SCUBA Massive Precluster Survey
(2005)We have started a large survey campaign (SCAMPS) to locate a statistical sample of massive precluster cores via their sub-mm continuum emission and to determine their physical and chemical properties. Here we present the ... -
Scan-time reduction using noise-matched images in 2- and 3-dimensional bismuth germanate PET/CT : clinical study in head and neck cancer
(2009)We quantitatively and qualitatively investigated 2-dimensional (2D) and 3-dimensional (3D) imaging with scan-time reduction in 14 patients with 17 lesions, who had known or suspected head and neck cancer, using a bismuth ... -
Scanning 6-wavelength 11-channel aerosol lidar
(2000-11)A transportable multiple-wavelength lidar is presented, which is used for the profiling of optical and physical aerosol properties. Two Nd:YAG and two dye lasers in combination with frequency-doubling crystals emit ... -
Scanning diffractometer for the rapid analysis of microparticles and biological cells
(1979-05-01)A laser diffractometer is described which employs a novel scanned array of optical light guides to record the angular intensity variation of light scattered radially by a particle throughout an arc of 180° in approximately ... -
SCATTER: A New Common Envelope Formalism
(2023-02-14)One of the most mysterious astrophysical states is the common envelope (CE) phase of binary evolution, in which two stars are enshrouded by the envelope shed by one of them. Interactions between the stars and the envelope ... -
Scattered broad optical lines in the polarized flux spectrum of the FR II galaxy 3C 321
(1996)The authors present optical/infrared broad-band filter polarimetry and optical spectropolarimetry of the powerful FR II galaxy 3C 321. The latter observations reveal a scattered broad component to the Hα emission line, ... -
Scattering from long prisms : a comparison between ray tracing combined with diffraction on facets and SVM
(University of Bremen, 2003)A new model suitable for rapid computation of scattering on faceted dielectric objects such as ice crystals, which combines ray tracing with diffraction on flat facets, is tested against SVM. Phase functions and asymmetry ... -
Scattering from long prisms using ray tracing combined with diffraction on facets
(2003)A new model suitable for rapid computation of scattering on faceted dielectric objects such as ice crystals is presented. It combines ray tracing with diffraction on flat facets. The model allows retaining the ray nature ... -
Scattering of non-uniform incident fields by long cylinders
(University of Bremen, 2003)We investigate experimentally far-field scattering from cylinders with illumination non-uniform along the axis of the cylinder. Scattered intensity as a function of angle in two orthogonal directions is examined. Variation ... -
Scenario analysis report with policy recommendations: An assessment of sustainability, resilience, efficiency and fairness and effective chain relationships in VALUMICS case studies : Deliverable 8.4
(University of Iceland, 2021-10-15)The functioning of food value chains entails a complex organisation from farm to fork which is characterised by various governance forms and externalities which have shaped the overall food system. VALUMICS food value chain ... -
Scenario Archetypes: Converging Rather than Diverging Themes
(2012-04-20)Future scenarios provide challenging, plausible and relevant stories about how the future could unfold. Urban Futures (UF) research has identified a substantial set (>450) of seemingly disparate scenarios published over ...
