The conservation and restoration of cultural heritage rely on technology products designed for other sectors. incorporation new equipment requires exhaustive studies to ensure the viability method linked safety technique, both operator artwork. For this purpose, research presents a preliminary approach study dry ice blasting its possible in field heritage. This technique is characterized by bei...

Abstract In manufacturing sector, looking for a balance between environmental and technical efficiency taking into account productivity is mandatory. Some sectors, such as the biomedical also needs to consider cleanness inherent prosthesis processes avoiding pathogens transfer human body, that is, neither chemicals, bacteria, nor uncontrolled metals can be introduced during surgical interventio...

The Large Hadron Collider Project LHC was approved by the CERN Council in December 1994. Commissioning with beam will start in the second half of 2005. The paper discusses the most important parameters, the general layout of the LHC octants, the status of the experiments ALICE, ATLAS, CMS and LHC-B, proton injection using the PS Booster, and the proton synchrotrons PS and SPS. Also described ar...

Optical magnetometers measure magnetic fields with extremely high precision and without cryogenics. However, at geomagnetic fields, important for applications from landmine removal to archaeology, they suffer from nonlinear Zeeman splitting, leading to systematic dependence on sensor orientation. We present experimental results on a method of eliminating this systematic error, using the hexadec...

Thermodynamic effects play an important role in the cavitation dynamics of cryogenics fluids. Such flows are characterized by strong variations in fluid properties with the temperature. A compressible, multiphase, one-fluid solver was developed to study and to predict thermodynamic effects in cavitating flows. To close the system, a cavitation model is proposed to capture metastable behaviours ...

Applications of cryogenics in space The development, in-orbit commissioning, and operation of cryogenic instrumentation in space raises the level of mission complexity, risk and associated cost. Any application must then be justified on the basis of its specific return. In the case of scientific missions, the cryogenic detectors and related payloads are the only candidates for the accomplishmen...

A horizontal hermetic scroll compressor has been developed for applications with high heatof-compression gases, including natural gas, air and helium (cryogenics). The compressor is a low profile horizontal design with oil-flooded cooling of the compression process. Combined with components required for oil separation and cooling, this design provides a smooth, continuous compression process fe...
