91. In situ consideration of resistance of bridge girder according to EC2 with AEMAna Brunčič, Andrej Štrukelj, Maja Kreslin, Andrej Anžlin, Aljoša Šajna, 2023, published scientific conference contribution Abstract: The paper presents a case study of a considerably cracked and degraded bridge in Slovenia: with the implementation of in-situ measurements under bending and shear and the use of a non-destructive acoustic emission technique. Despite the existing crack system, the latter was able to detect microstructural changes. These were characterised by low values of average frequency (AF), as well as lower values of the rise time-amplitude ratio (RA), and energy. A correlation between shear capacity and acoustic activity was observed. This promises to expand the use of AE in the process of assessing of the load-bearing capacity of existing concrete structures.
Keywords: shear resistance, shear crack, crack width, acoustic emission (AE) parameters, bridge girder, stiffness, elasticity, damage evaluation

97. Epidemiologija raka dojk in presejanjeMaja Primic-Žakelj, Vera Pompe-Kirn, 1998, review article Abstract: Rak dojk je v Sloveniji najpogostejši rak pri ženskah. Leta 1995 je za njim zbolelo 784 žensk (76,7/100.000), pričakujemo pa , da se bo v prihodnjih desetih letih incidenca še večala. Delež rakov, odkritih v omejenem stadiju se povečuje; leta 1995 je bilo takih 44% vseh primerov. Čeprav se je preživetjolnic izboljšalo (67-odstotno 5-letno relativno preživetje bolnic z rakritim v letih 1988-92), ostaja rak dojk pri ženskah na prvem mestu med vzroki smrti zaradi raka. Med dikazane nevarnostne dejavnike sodijo poleg spola in starosti še poprejšnji rak dojk , nekatere benigne bolezni dojk, družinska obremenitev, ionizirajoče sevanje, nekateri reproduktivni dejavniki in debelost. V primarni preventivi zaenkrat ni posebnih priporočil, so le splošna: vzdrževanje normalne telesne teže, pravilna prehrana, telesna dejavnost in zmernost pri pitju alkoholnih pijač. Ocenjujejo, da presejanje, redno mamografsko pregledovannje žensk po 50. letu starosti z dodatnim kliničnim pregledom ali brez njega, zmanjša umrljivost za rakom dojk med pregledanimi za okrog 30%. Populacijsko presejanje priporočajo večinoma po 50.letu starosti. Problem raka dojk je mogoče reševati celostno, s primarno preventivo, zgodnjim odkrivanjem in dostopnostjo do užinkovitega zdravljenja, predvsem pa z vlaganjem sredstev tja, kjer je razmerje med stroški in koristjonajugodnejše.

99. A Raman microspectroscopy-based comparison of pigments applied in two gothic wall paintings in SloveniaMaja Gutman, Ajda Mladenovič, Anabelle Križnar, Sabina Dolenec, 2019, original scientific article Abstract: The present study deals with the characterisation of pigments used in two overlaid gothic wall paintings from the former 13th century Minorite church of St. Francis of Assisi (Koper, Slovenia), in order to define differences in the technologies used. Paint layer samples were analysed via Raman microspectroscopy, supported by SEM/EDS and FTIR analysis, when necessary. The results revealed that the 14th century mural was painted mainly a fresco with final elements a secco, a technique typical of Italian mediaeval wall painting. In contrast, the 15th century painting was executed mostly a secco, a technique often applied in Northern Europe and the Alpine region. The differences between the two paintings are especially obvious in the pigments applied. While the earlier painting is characterised by azurite, carbon black, red and yellow ochres, lime white and green earth, the palette used for the younger painting is much broader. In addition to red and yellow ochres, carbon black and lime white, lead pigments such as lead white, red lead and lead-tin yellow type I were also determined, as well as a number of expensive pigments including cinnabar, azurite and malachite. Also found in the younger painting was the rare orange yellow pigment vanadinite. In both layers, azurite was applied a secco for the background area. Gilding was confirmed in both layers, carried out as application of gold leaves on red bole (in the earlier mural) and on mordant (on a younger, superimposed (overlaid painting), which is quite exclusive and rare for Slovene mediaeval painting. In the younger layer also a use of tin foil for secondary elements was discovered.
