183. The influence of calcium sulfate content on the hydration of belite-calcium sulfoaluminate cements with different clinker phase compositionsMaruša Mrak, Frank Winnefeld, Barbara Lothenbach, Sabina Dolenec, 2021, original scientific article Abstract: The influence of different amounts of gypsum on the hydration of a belite-rich and a yeʼelimite-rich belite-calcium sulfoaluminate clinker (BCSA) was investigated. The hydration kinetics, phase assemblages and compressive strength development of cements prepared using yeʼelimite/ calcium sulfate molar ratios of 1, 1.5 and 2 were studied. Besides ettringite and monosulfate, aluminium hydroxide, strätlingite, C-S-H, iron-containing siliceous hydrogarnet and hydrotalcite were present as hydration products. Increasing the amount of gypsum increased the ratio of ettringite to monosulfate formed in the cement paste, lowered the amount of pore solution, delayed the dissolution of belite and ferrite, decreased the formation of strätlingite and, in the case of the yeʼelimite-rich BCSA, led to an increase in compressive strength. Increased amounts of belite in the clinker led to the formation of higher quantities of C-S-H, at the expense of straätlingite and a lower compressive strength, as belite has a lower degree of reaction than yeʼelimite and due to the formation of more C-S-H and stratlingite compared to the more space-filling ettringite. The thermodynamic model established for BCSA cement hydration agrees well with the experimental data. Compressive strength directly correlated with bound water from thermogravimetric analyses and inversely correlated with the porosity calculated from thermodynamic modelling.

184. Stresni zlomi medenice po zdravljenju z obsevanjem : pregled literatureJan Žagar, Barbara Šegedin, 2023, review article Abstract: Stresni zlomi medenice po obsevanju so že dolgo znana posledica obsevanja tumorjev v področju medenice. Čeprav so zlasti v področju sakruma relativno pogost pojav, je njihova diagnostika zaradi nespecifičnosti simptomov težavna. V tem preglednem članku smo pregledali literaturo, ki zajema etiologijo, incidenco, dejavnike tveganja, simptome in diagnostiko ter zdravljenje in preprečevanje stresnih zlomov medenice po obsevanju. Na podlagi pridobljenih podatkov smo poskušali strniti in predstaviti najdene ugotovitve z navedenih področij, ki bi nam bile lahko v pomoč v vsakodnevni radioterapevtski klinični praksi, saj standardiziranih priporočil na tem področju nismo našli.

185. Kazalniki kakovosti v radioterapijiAna Perpar, Barbara Šegedin, 2023, review article Abstract: Zagotovitev kakovosti v zdravstvu postaja pomembnejša dejavnost plačnikov in ponudnikov zdravstvenih storitev, prav tako mednarodne organizacije uspešno akreditacijo pogojujejo z izvajanjem programov nadzora kakovosti. Za analizo pomanjkljivosti v zagotavljanju storitev se uporabljajo kazalniki kakovosti, ki analizirajo strukture, procese in izide v zdravstvenem sistemu in s tem omogočijo načrtovanje in izvedbo izboljšav zdravstvenih storitev. V radioterapiji je tradicija nadzora kakovosti, ki se razvija vzporedno s tehnološkimi in metodološkimi spremembami na tem področju. Pri analizi izidov zdravljenja, ki so najbolj poveden kazalnik kakovosti onkoloških zdravstvenih storitev, se velikokrat srečujemo z nezanesljivostjo podatkov oz. zapletenim dostopom do njih, kar zmanjšuje ažurnost in verodostojnost rezultatov.

189. Climate, host and geography shape insect and fungal communities of treesIva Franić, Eric Allan, Simone Prospero, Kalev Adamson, Fabio Attorre, Marie-Anne Auger-Rozenberg, Sylvie Augustin, Dimitrios N. Avtzis, Wim Baert, Marek Barta, Maarten De Groot, Barbara Piškur, 2023, original scientific article Abstract: Non-native pests, climate change, and their interactions are likely to alter relationships between trees and tree-associated organisms with consequences for forest health. To understand and predict such changes, factors structuring tree-associated communities need to be determined. Here, we analysed the data consisting of records of insects and fungi collected from dormant twigs from 155 tree species at 51 botanical gardens or arboreta in 32 countries. Generalized dissimilarity models revealed similar relative importance of studied climatic, host-related and geographic factors on differences in tree-associated communities. Mean annual temperature, phylogenetic distance between hosts and geographic distance between locations were the major drivers of dissimilarities. The increasing importance of high temperatures on differences in studied communities indicate that climate change could affect tree-associated organisms directly and indirectly through host range shifts. Insect and fungal communities were more similar between closely related vs. distant hosts suggesting that host range shifts may facilitate the emergence of new pests. Moreover, dissimilarities among tree-associated communities increased with geographic distance indicating that human-mediated transport may serve as a pathway of the introductions of new pests. The results of this study highlight the need to limit the establishment of tree pests and increase the resilience of forest ecosystems to changes in climate.
