An X-ray tomography device for providing a 3D image of a sample comprising a X-ray source, a cell, a photon detector and a processing unit. The processing unit computes the 3D tomography image on the basis of the acquired images corresponding to a plurality of cell angles. The cell is positioned so as the photon detector senses mainly photons coming from the sample inside the cell, and the photon detector is overexposed to cancel pixels corresponding to photons not coming from the sample.

This review gives an overview on the analysis of inorganic nickel species and their toxic effects. Based on the analytical procedure applied inorganic nickel species are usually classified in soluble, sulfidic, metallic and oxidic nickel fractions. Only few works were attempting a chemical characterization of the different nickel compounds in each fraction. This general classification in four nickel species groups is widely used in toxicological studies dealing with nickel particulate matter in workplace air. Compared to the general population, occupationally exposed people have a higher risk of respiratory tract cancer due to inhalation of nickel at their workplace in the nickel-producing or using industries. High cancer risk is related to less soluble oxidic and especially sulfidic nickel species in refinery dust. In contrast, within the general population the most harmful health effect related to nickel exposure is allergic contact dermatitis due to prolonged skin contact with nickel. Absorption processes of nickel species and molecular mechanisms of nickel toxicity are briefly outlined. © 2012 Elsevier GmbH. Source

A system supervises applications executing on electronic devices connected by one or more networks. Each device comprises a local supervision entity, cooperating to control the applications. Each application comprises a set of application components, each encapsulated in a container by the supervision entity of the device hosting the component. The components are connected by connectors. The supervision entity of a source device executes, in response to receipt of a command to migrate a component to a target device: stopping the component, interrupting arrival of data in the input connectors of the component, serializing and encapsulating the properties of the component in a container of the supervision entity, dispatching a migration request message to the supervision entity of the target device, the message comprising the serialized and encapsulated component, and redirecting the connectors of the component as a function of the state of connections of each connector on the source device.
