Magnetic resonance imaging (MRI) instrumentation is vulnerable to technical and image quality problems, assurance essential. In the studied regional center long-term has been based on MagNET phantom measurements. American College of Radiology (ACR) an accreditation program including a standardized measurement protocol phantom. The ACR includes recommended acceptance criteria for clinical sequences thus provides possibility assess relevance assurance. purpose this study was test MRI in...

A multicategory sea ice model that explicitly takes into account redistribution of undeformed categories ridged and rafted is introduced with the intention investigating simulation open water fraction within ice. The performance this compared a reduced accounts for only two categories, latter type sea‐ice being most widely used in global climate models. Two idealized scenarios are considered: polynya formation along coastline under offshore winds low‐pressure system passing over an field....

High temperature densification of oxide glasses influences their interatomic distances and bonding patterns, resulting in changes the mechanical chemical properties. Most high-pressure investigations have focused on aluminosilicate aluminoborosilicate based glasses, due to relevance for glass industry as well geological sciences. Relatively few studies explored pressure-induced structure properties phosphate although P2O5 is an important component various multicomponent industrial interest....

Three types of silicate glass fibers are annealed, simultaneously stretched in the transition region for certain time lengths, then slowly cooled to room temperature under load, and subsequently scanned by differential scanning calorimetry (DSC). During DSC scanning, a broad exothermic peak (representing energy release) occurs well below temperature, while it does not occur non‐stretched fibers. The indicates that mechanical stretching can result an enhancement It also confirms released...
