A system enabling both x-ray fluoroscopy and MRI in a single exam, without requiring patient repositioning, would be a powerful tool for image-guided interventions. We studied the technical issues related to acquisition of x-ray images inside an open MRI system (GE Signa SP). The system includes a flat-panel x-ray detector (GE Medical Systems) placed under the patient bed, a fixed-anode x-ray t...
Polymer concrete (PC) is a composite construction material that boasts several advantages, such as lightness, low water permeability, high resistance to corrosive environments, and chemical degradation. Consequently, it has recently attracted interest an alternative the traditional ones for civil applications. In this study, unsaturated polyester resin was considered matrix phase of PC. Aimed p...
The aim of this work was to study the relationship between capillary tube flow and the acoustic behavior of household refrigerators by investigating a particular type of fluid-induced noise, known as fluctuating noise. To this end a household refrigerator was carefully instrumented and firstly tested in a reverberant chamber and secondly in a climate-controlled chamber. Acceleration measurement...
Structure of the intermediate state in type-I superconducting lead (Pb) is shown to be very sensitive to the ramp rate of an applied magnetic field. The configurations of resulting static patterns depend sensitively on the shape of the specimen. In particular, geometric barrier, present in the samples with rectangular cross-section, plays an important role in determining the sharp boundary betw...
