1982. Ultra-high strenght TWIP steel with high chromium contentPavel Podaný, Tomáš Studecký, Tomas Gregor, Radek Prochazka, Aleksandra Kocijan, 2023, izvirni znanstveni članek Povzetek: A new ultra-high strength steel with a fully austenitic microstructure and twinning-induced plasticity (TWIP) effect has been developed. TWIP effect gives this steel a good combination of high strength of over 1000 MPa and ductility of over 35%. This new steel has a high chromium content, which increases its corrosion resistance. By combining cold rolling and annealing, the steel has achieved a very fine austenitic microstructure with an average grain diameter of 2.85 µm. This steel could be used for structural applications or components that need to withstand high levels of stress, deformation and corrosion environment.

1987. Magnetic resonance spectroscopy: an overview of the method and its applicationin clinical neuroradiologyAleš Koren, 2002, izvirni znanstveni članek Povzetek: Background. Magnetic resonance spectroscopy (MRS) is a comparatively new diagnostic method. Brain tissue is very suitable for MRS analysis. In practice, only a small number of compounds present in the brain may be analysed by MRS. The utility of MRS in neuroradiology and clinical practice isconstantly growing since the investigation is of help in the differential diagnosis of pathological processes as well as in assessing the progress of a disease and evaluating the outcome of treatment. In analysing the data obtained, a number of factors that may influence the objectivity of the resultmust be taken into account. The magnetic resonance scanner located at the Institute of Radiology, University Medical Centre Ljubljana, utilises modern MRS protocols and has proved a valuable tool in the diagnostic evaluation of neurologic diseases. Conclusions. MRS provides spectral analysisof substance in a selected volume of tissue, thereby offering an insight into the metabolic state of the tissue.

1988. Gastroparesis in a young diabetic patientPrimož Kovačič, Breda Jamar, 2002, izvirni znanstveni članek Povzetek: Background. Gastroparesis is defined as a delay in emptying of contents from the stomach and occurs in a variety of conditions, e.g. after vagotomy or in systemic diseases such as diabetes mellitus, scleroderma and amyloidosis. The purpose of this paper is to present the radiologic examination, a simple, reliable and noninvasive method as an alternative to other methods for the assessment of gastric emptying. Case report. A twenty-one years old female wasadmitted because of suspected autonomic neuropathy. She had insulin dependent diabetes mellitus type 1 for the last ten years. At the time of admission she was complaining of nausea, vomiting weakness and occasional dizziness. A barium study of oesophagus and stomach was performed: oesophagus was dilated and aperistaltic, remnants of food were seen in aperistaltic stomach but no obstruction, causing delayed emptying, was found. Conclusions. Scintigraphy is at the present the standard technique for the assessment of gastric emptying. Ultrasonography, magnetic resonance imaging; electrogastrography, gastroduodenal manometry and emptying of radiopaque pellets are also used for the evaluation of gastric motility in cases of delayed gastric emptying. The role of barium studies remains to be established. Objavljeno v DiRROS: 31.01.2024; Ogledov: 270; Prenosov: 65 Celotno besedilo (79,86 KB) |
