31. Use of steel slag for the synthesis of belite-sulfoaluminate clinkerLea Žibret, Martina Cvetković, Maruša Mrak, Mojca Loncnar, Andrej Ipavec, Sabina Dolenec, 2020, objavljeni znanstveni prispevek na konferenci Povzetek: Belite-sulfoaluminate (BCSA) cements are low-carbon mineral binders, which require low energy consumption and allow the incorporation of various secondary raw materials in the clinker raw meal. In this study two types of unprocessed steel slags, coming from stainless steel production, were incorporated in the BCSA clinkers. The clinker phase composition, clinker reactivity, and the compressive strength of the cement were studied to evaluate the possible use of the slag in BCSA clinkers. The cement clinkers were synthesized by using natural raw materials, white titanogypsum, mill scale, as well as two different steel slags: (i) EAF S slag, which is a by-product of melting the recycled steel scrap in an electric arc furnace, and (ii) la dle slag as a by-product of the processes of secondary metallurgy, in various quantities. Raw mixtures with two different targeted phase compositions varying in belite, calcium sulfoaluminate and ferrite phases were sintered at 1250 °C. Clinker phases were determined by Rietveld quantitative phase analysis, while their distribution, morphology and incorporation of foreign ions in the phases were studied by SEM/EDS analysis. The clinker reactivity was determined by isothermal calorimetry. BCSA cements were prepared by adding titanogypsum. The compressive strength of the cement pastes was determined after 7 days of hydration. The presence of a predicted major clinker phases was confirmed by Rietveld analysis, however periclase was also detected. Microscopy revealed subhedral grains of belite and euhedral grains of calcium sulfoaluminate phases, while ferrite occurred as an interstitial phase. The results showed differences in the microstructure and reactivity of the clinker and cement, which can be attributed to varying amounts of ettringite due to different slag types Ključne besede: belite-sulfoaluminate cement, cement clinker, steel slags, clinker microstructure, cement reactivity Objavljeno v DiRROS: 19.01.2024; Ogledov: 208; Prenosov: 84 Celotno besedilo (18,89 MB) Gradivo ima več datotek!

35. Long term follow-up after radiosynovectomy with yttrium 90 in patients with different rheumatic diseasesMojca Golja, Nataša Budihna, Igor Batagelj, 1997, izvirni znanstveni članek Povzetek: The aim of the retrospective study was to evaluate the efficacy of radiosynovectomy (with yttrium 90) mainly in patients with rheumatoid arthritis, less with some other rheumatic diseases. The evaluation period varied from half to nine years. The procedure was performed in 273 patients (225 females, 48 males) or in 463 joints (402 knees, 61 shoulders and ankles).The effects was evaluated by change in degree of morning stiffiness, pain and swelling (score from 0 to 9). Very good results were obtained in 69 (15%), good in 142 (30.5%), moderate in 197 (42.5%) and no effect in 55 (12%) joints. Six months after the procedure 38 joints (8%), half to two years after221 joint (48%) were in good remission, after 3 to 4 years 95 joints (20%), after 5 to 6 years 57 joints (12%) were well, 7 to 9 years later 52 joints (11%) showed no signs of arthritis. Joint pain and swelling were the most frequent procedure complications (5.6%). In two patients with additional immunomodulating therapy chronic myeloid and lymphocityc leukaemia were diagnosed. Radiosynovectomy is considered to be an effective and safe treatment for synovitis indifferent rheumatic diseases.

Prognostic value of staging laparotomy in supradiaphragmatic clinical stage I and II Hodgkin's diseaseMarjeta Vovk, Tatjana Šumi-Križnik, Marija Jenko-Fidler, Gabrijela Petrič-Grabnar, Marinka Kremžar, Janez Novak, Mojca Senčar, Branko Zakotnik, Alenka Vodnik-Cerar, Branimir Jakšić, 1996, izvirni znanstveni članek Povzetek: In the period 1974-1989, 219 patients with supradiaphragmatic clinical stage I and II Hodgkin's disease were treated at the Institute of Oncology in Ljubljana; of these 95 (43%) patients underwent staging laparotomy. Of laparotomized patients, those with pathological stage III-IV, and of non-laparotomized, those with unfavorable prognostic factors (B-symptoms, bulky mediastinum) received chemotherapy: the remaining patients were treated by irradiation. No statistically significant difference in the survival and disease-free survival between laparotomized and nonlaparotomized patients could be found.
