Heating rate and energy gradient from the tropics to the North Pole
Luca Ferrero, Martin Rigler, Asta Gregorič, Griša Močnik, 2024, published scientific conference contribution abstract

Abstract: Absorbing aerosol species, such as Black (BC) and Brown (BrC) Carbon, are able to warm the atmosphere. The role of aerosols is one of the least clear aspects in the so called “Arctic Amplification” (AA) and up to now this was mostly modelled [1,2]. For this reason, we took part in four scientific cruises (AREX, Arctic-Expedition, summer 2018, 2019, 2021 and EUREC4A, 2020) in the North Atlantic, eastward and south-eastward of Barbados, aiming at the determination of the aerosol chemical composition and properties from the Tropics to the North Pole. The Heating Rate (HR) was experimentally determined at 1 minute time-resolution along different latitudes by means of an innovative methodology [3], obtained by cumulatively taking into account the aerosol optical properties, i.e. the absorption coefficients (measured by AE33 Aethalometer) and incident radiation (direct, diffuse and reflected) across the entire solar spectrum. The HR computed along AREX and in Milan (in the same period) were used to determine the energy gradient, due to the LAA induced heat storage at mid-latitudes, which contributes to AA through the atmospheric heat transport northward. Moreover, aerosol chemical composition was achieved by means of sampling via high volume sampler (ECHO-PUF Tecora) and analysis via ion chromatography, TCA08 for Total Carbon content, Aethalometer AE33 (for BC), ICP-OES for elements. A clear latitudinal behaviour in Black Carbon concentrations, with the highest values at low latitudes (e.g. average BC concentration in Gdansk up to 1507±75 ng/m3) and a progressive decrease moving northwards and away from the big Arctic settlements (Black Carbon concentrations within the 81st parallel: 5±1 ng/m3). According to the latitudinal behaviour of BC concentrations and solar radiation (decreases towards the north while the diffuse component increases), HR decreases noticeably towards the Arctic: e.g. higher in the harbor of Gdansk (0.290±0.010 K/day) followed by the Baltic Sea (0.04±0.01 K/day), the Norvegian Sea (0.010±0.010 K/day) and finally with the lowest values in the pure Arctic Ocean (0.003±0.001 K/day). Accordingly, the energy density added to the system by the aerosol, a positive forcing that differs by 2 orders of magnitude between mid-latitudes and North Pole was found: 347.3 ± 11.8 J/m3 (Milan), 244.8 ± 12.2 J/m3 (Gdansk) and 2.6 ± 0.2 J/m3 (80°N). These results highlight the presence of a great energy gradient between mid-latitudes and Arctic that can trigger a heat transport towards the Arctic. Moreover this was strengthen by the HR value for EUREC4A in Barbados that was 0.175±0.003 K/day. Finally, preliminary results from Antarctica collected onboard the Italian RV Laura Bassi cruising the Southern Ocean and the Ross Sea will be shown.     Acknoledgements: GEMMA Center, Project TECLA MIUR – Dipartimenti di Eccellenza 2023–2027.

The representations of female sexual desire in the works of Zofka Kveder (1878-1926)
Katja Mihurko, 2023, published scientific conference contribution abstract

Abstract: The paper examines Zofka Kveder's letters to discover the ways in which she depicts her own sexual experiences, including orgasm. Mihurko Poniž will also look for representations of sexual desire in Kveder's literary texts written in Slovenian, German, Czech and Croatian language. The latter show that Kveder was obviously not as open and direct when writing literature. Through the analysis of letters to her friends and journal editors, Kveder's struggles against the censorship of her texts by editors will be presented. These findings will be embedded in the broader historical context of bourgeois double standards and their consequences not only for women in general but for women writers in particular. The issue of (self-)censorship will be touched upon and discussed in the context of Kveder's work. Being in a special position of an author between cultures, Kveder was allowed a certain freedom in the representation of female sexual desire, which would probably not have been possible if she had been perceived only as a Slovenian writer. Therefore, the paper will explore the intersection of nationality, literature, and sexuality in the case of Zofka Kveder’s works and ego-documents.

Katja Mihurko, 2023, published scientific conference contribution

Abstract: Prispevek je prva raziskava, ki je v celoti posvečena Adi Kristan (1876–1925). V njem predstavljamo njeno življenje in literarno ter publicistično delo, leposlovna besedila in članke, ki so povezani z njenim delovanjem v Jugoslovanski demokratski stranki ter njeno dopisovanje z Ivanom Cankarjem.
Keywords: slovenska moderna, intimnost

Čustvena pokrajina materinstva in materinjenja v elektronski zbirki Pisma
Katja Mihurko, 2023, published scientific conference contribution abstract

Abstract: Raziskovanje dojemanja materinstva in čustev, ki so se porajala ob materinjenju, je v preteklosti omejeno na pisne vire: sodne zapisnike, publicistične zapise, literarna dela in ego dokumente. V pismih in dnevnikih so izkušnja materinjenja in premisleki o njej največkrat izraženi bolj neposredno kot v publicističnih ali literarnih delih. Vendar so ego dokumenti, še posebno t. i. navadnih ljudi, težje dosegljivi, saj se niso tako sistematično ohranjali kot tiskana besedila in sodni zapisniki. Zato so pisma, ki so objavljena v elektronski zbirki Pisma, dragocena pričevanja o materinstvu in materinjenju ter z njima povezanimi čustvi ljubezni, veselja, žalosti, jeze in strahu. V prispevku bom predstavila možnosti iskanja vsebin, ki so povezane z materinstvom in materinjenjem v omenjeni elektronski zbirki. Na osnovi vizualizacij zbirke bom najprej pokazala, s katerimi tematikami se povezuje tematika materinstva in materinjenja v dopisovanjih avtoric slovenske moderne ter družine Kremenšek Boršnik, nato pa še kako o tem pišeta meščanka (Ivanka Kremenšek, poročena Boršnik) in slovenska pisateljica (Zofka Kveder) konec 19. in v začetku 20. stoletja.
