Study of the influence of tin substitution on the structural, superconducting and magnetic properties of a high-temperature superconductor of the Eu-123 type

(Investigators: A. Cigáň, A. Dvurečenskij, M. Škrátek, M. Majerová, J. Maňka) Polycrystalline samples with a nominal composition of EuBa2Cu3-xSnxO7-δ, where x = 0 to 1.5, were prepared by the solid phase reaction method at 1050 ° C in an oxygen atmosphere. Their structural, superconducting and magnetic characteristics were analyzed based on the results of polarizing…

Optimized 3D imaging of biological objects by X-ray microtomography methods

Optimized X-ray microtomographic methodologies of three-dimensional visualization of biological objects and their internal microstructures were developed. Optimization of microtomographic measurements for a specific object included the choice of target material, optimized acceleration voltage and X-ray tube current, signal accumulation time on the detector, number of repetitions, choice of relaxation time between two measurements and number…

Clustering of symptoms of intracranial pressure time series for estimation of alarm function in traumatic brain injuries

Investigators: M. Teplan, I. Bajla, R. Rosipal) When monitoring patients with severe head injury, the so-called method is used in clinical practice. critical value of the intracranial pressure time course (VLT). Exceeding this threshold is evaluated as an alarm situation, on the basis of which the medical staff initiates an emergency procedure (protocol) to save…

New methods of ensuring homogeneous signal excitation for determination of energy metabolism of skeletal muscles, liver and heart on 7T MRI tomography

(Investigators: L. Valkovič, I. Frollo) Phosphorus MR spectroscopy (31P-MRS) is a unique technique that allows non-invasive measurement of tissue energy metabolism in vivo. However, due to the low signal-to-noise ratio (SNR), it is still not commonly used in medical practice. MR systems with a magnetic field strength of 7T in combination with surface coils achieve…
