THREE PROBLEMS IN RELATION TO Luciano Floridi's work on the Philosophy of Information (PI) and the relationship of PI to Library and Information Science (LIS) are considered: the claim that LIS is a materials-based discipline, Floridi's claim about Information as a message transfer system, and his downgrading of Social Epistemology to be a subset of PI. The(More)
This review reports data on the general and renal tolerance of the paramagnetic contrast agent Gd-DTPA after intravenous administration. Gd-DTPA was administered usually at a dose level of 0.1-0.2 mmol/kg body wt (range: 0.005-0.25 mmol/kg body wt) in cranial, spinal and body MR indications. In phase I-IIIa studies a total of 2154 healthy volunteers and(More)
Dynamic intensity-modulated radiotherapy (D-IMRT) using the sliding-window technique is currently applied for selected treatments of head and neck cancer at Institute for Cancer Research and Treatment of Candiolo (Turin, Italy). In the present work, a PiXel-segmented ionization Chamber (PXC) has been used for the verification of 19 fields used for four(More)
Cloud computing allows for vast computational resources to be leveraged quickly and easily in bursts as and when required. Here we describe a technique that allows for Monte Carlo radiotherapy dose calculations to be performed using GEANT4 and executed in the cloud, with relative simulation cost and completion time evaluated as a function of machine count.(More)
Often CAD models already exist for parts of a geometry being simulated using GEANT4. Direct import of these CAD models into GEANT4 however, may not be possible and complex components may be difficult to define via other means. Solutions that allow for users to work around the limited support in the GEANT4 toolkit for loading predefined CAD geometries have(More)
The objective of this session was to present different arguments for and against unity in LIS to provide different perspectives on the conference themes, in particular, 'theoretical and conceptual approaches to the study of the communication of information', and provide a forum for debate and discussion. Three perspectives were proposed through short(More)
The development of microdosimeters and particle telescopes is important for risk assessment in space and aviation applications. The charge collection properties of a monolithic particle telescope, suitable for both microdosimetry and fluence based approaches, were studied using an ion microprobe.
