Atmosphere–cryosphere interactions during the last phase of the Last Glacial Maximum (21 ka) in the European Alps
Costanza Del Gobbo, Renato R. Colucci, Giovanni Monegato, Manja Žebre, Filippo Giorgi, 2023, original scientific article

Abstract: Evidence that during the Last Glacial Maximum (LGM) glaciers extended well into the piedmont plains is still identifiable in the alpine foreland as a system of well-preserved moraines. Glaciers are strongly controlled by temperature and precipitation, and therefore, they are excellent indicators of climate change. Here, we use a regional climate model (RCM) to investigate some of the physical processes sustaining Alpine glaciers during the last phase of the LGM during Greenland Stadial 2 at 21 ka. We find a predominance of convection during summer and increased southwesterly stratiform precipitation over the southern Alps when compared to pre-industrial (PI) conditions. This precipitation pattern, along with lower temperatures, determined summer snowfall extending to low elevations, with a consequent substantial drop of the equilibrium line altitude (ELA), which is consistent with the estimated LGM glacier extent. Our RCM-based estimates of 21 ka ELA at the LGM yield excellent consistency with Alpine ELA reconstructions, further demonstrating the great potential of this technique for use in palaeoclimate studies.

Effects of selected printing parameters on the fire properties of 3D-printed neat polylactic acid (PLA) and wood/PLA composites
Nataša Knez, Mirko Kariž, Friderik Knez, Nadir Ayrilmis, Manja Kitek Kuzman, 2021, original scientific article

Abstract: The effects of selected printing parameters on the fire properties of additively produced composites from neat polylactic acid (PLA) and wood/PLA filaments were investigated. The reaction to fire of the 3D-printed specimens was tested according to the ISO 5660-1 cone calorimeter test method. The results showed that the properties of the specimens when exposed to fire were significantly affected by the incorporation of wood flour into the PLA filament. It was also interesting that PLA specimens had much better reactions to fire than the wood/PLA specimens. Time to ignition was found to be much longer in the 3D-printed PLA specimens. Although the maximal heat release rate was a little higher in the PLA than the wood/PLA specimens, the duration of HRR was longer for the wood/PLA specimens. The initial mass of the specimens was smaller in the wood/PLA composites, but during the radiant heat exposure the mass typically decreased slower than in the PLA specimens.

Novosti pri obsevanju raka telesa maternice
Helena Barbara Zobec Logar, Manja Šešek, 2023, published scientific conference contribution

Abstract: Rak materničnega telesa je heterogena bolezen. Pooperativno zdravljenje z obsevanjem ne temelji več samo na patohistoloških kriterijih, čedalje pomembnejšo vlogo ima molekularna klasifikacija, ki omogoča dodatno razvrščanje rakov v rizične skupine.

Biokemična ponovitev raka prostate
Manja Šešek, 2023, published scientific conference contribution

Abstract: Ob pojavu biokemične ponovitve raka prostate po radikalni prostatektomiji lahko z reševalnim obsevanjem dosežemo dolgotrajno kontrolo bolezni. Na uspešnost zdravljenja pomembno vpliva višina vrednosti PSA pred pričetkom zdravljenja z obsevanjem. Pravočasen pričetek reševalnega obsevanja nudi enako biokemično kontrolo bolezni kot pooperativno obsevanje, manj bolnikov pa je izpostavljenih stranskim učinkom dodatnega zdravljenja z obsevanjem. Uvedba PSMA PET/CT slikanja pri bolnikih z biokemično ponovitvijo raka prostate bi lahko spremenila standardno zdravljenje pri dveh tretjinah bolnikov.

Oligometastatski rak

Abstract: Oligometastatska bolezen (OMB) predstavlja vmesno stanje med lokalno napredovalo boleznijo in obsežnejšo metastatsko boleznijo. Zaenkrat ne poznamo specifičnih biomarkerjev, ki bi nam pomagali opredeliti bolnike z majhnim bremenom bolezni, zato diagnoza OMB temelji na slikovni diagnostiki. V zadnjih letih narašča zanimanje za optimizacijo zdravljenja OMB predvsem zaradi obetavnih rezultatov dodatka lokalnega k obstoječemu sistemskemu zdravljenju. S takšnim načinom zdravljenja se je prvič pokazala možnost doseganja dolgotrajnih zazdravitev ali redko celo ozdravitev teh bolnikov. Razlikovanje posameznih vrst OMB in njihovo enotno poimenovanje je pomembno zlasti v kliničnih raziskavah, saj nam omogoča medsebojno primerjavo rezultatov različnih raziskav.

Abstract: Comprehensive glacial Quaternary studies involving geochronological methods, modelling of ice topography with the support of field geomorphological and geological data in the Balkan Peninsula are relatively scarce, although there is evidence of past glaciations in several mountain ranges. Here, we present research on the extent and timing of past glaciations on the northern Velebit Mt. in coastal Croatia and inferences of the climate during that time. Based on geomorphological and sedimentological evidence and using cosmogenic 36Cl surface exposure dating of moraine boulders, we provide an empirical reconstruction of past glaciers and compare this with the Parallel Ice Sheet Model (PISM) simulations under different palaeoclimate forcings. The dating results show that the northern Velebit glaciers reached their maximum extent during the last glacial cycle before the global Last Glacial Maximum (LGM). Maximum ice extent likely correlates with Marine Isotope Stage 5–4, although the exact timing cannot be determined at this point due to poorly known site- and time-specific denudation rates. Empirical reconstruction of the maximum extent suggests that the area covered by glaciers was ~116 km2. The-best fit PISM simulation indicates that the most likely palaeoclimate scenario for the glaciers of this size to form is a cooling of ~8 °C and a 10% reduction in precipitation from present-day levels. However, the best-fit simulation does not correctly model all mapped ice margins when changes in climatological parameters are applied uniformly across the model domain, potentially reflecting a different palaeoprecipitation pattern to today.
