Giustina Selvelli, 2018, original scientific article

Abstract: This paper describes the linguistic and identitary challenges faced by the members of the Armenian diaspora of Plovdiv, Bulgaria, in relation to what can be viewed as an irreducible multicultural context. Through the consideration of the community’s main cultural institutions embodied by the AGBU organization, the related press organ Parekordzagani Tzain and publishing house Armen Tur, I highlight the Armenian diaspora’s ability of combining different resources from a transnational perspective, while keeping alive a fixed sense of collective identity. In such process, I show how language reveals itself as the main chore of the community’s value systems, embracing different domains of the diaspora social and cultural life.
Keywords: Armenian diaspora, Multilingualism in Bulgaria, Armenians in Plovdiv, Armenian institutions, Bulgarian Armenians.

Giustina Selvelli, 2018, original scientific article

Abstract: This paper intends to shed light on the memory of the Armenian Genocide among the Armenian diaspora in Plovdiv, Bulgaria. I will focus on the patterns of promoting remembrance found in the local Armenian press and literature, on initiatives of the Armenian General Benevolent Union/Parekordzagan (AGBU) to celebrate the ninetieth and hundredth anniversaries of the Genocide, and on analyzing the cityscape of Plovdiv in terms of the monuments, the museum, and the cemetery of its Armenian community. To that end, I will employ information collected during interviews, articles from Plovdiv’s main Armenian newspaper, and data I gathered while visiting the community’s public spaces. I will demonstrate the importance of collective memory and remembrance of the Genocide to the preservation of the internal cohesion of the Armenian community of Plovdiv and its ethnic identity. Taking a socio-anthropological approach, I will argue that the maintenance and promotion of a specific “postmemory” of the Genocide depends heavily on the activities and initiatives of the main diaspora organization, the AGBU, on its selection of specific symbols, and on the emotional content of its communications.

Abstract: Sto let po koncu prve svetovne vojne in po tem, ko so bile večplastne identitete, večjezičnost in kulturna hibridnost s trdo roko izkoreninjene s tega območja, si še nismo prišli povsem na jasno o nacionalnih ambicijah in etičnih omejitvah naše „jedrske“ družbe ter z njimi povezani potrebi po kritičnem vrednotenju naše vojskovanja polne zgodovine, ki nam je danes še ni uspelo pozabiti.

Giustina Selvelli, original scientific article

Abstract: In this paper, I focus on the role played by material objects in the evocation of a specific imaginary of the recent past (mainly the 1970s and 1980s) in the literary works of Bulgarian writer Georgi Gospodinov (in the novels “The Physics of Sorrow” and “Natural Novel”) and of Turkish novelist Orhan Pamuk (in “The Museum of Innocence”). I analyze the presence of feelings of melancholy and loss accompanied by a fixation on objects in the fictional works and describe their possible overcoming through an externalization in the form of museum exhibitions in the city of Sofia and Istanbul such as the “Inventory depository of Socialism” and the “Museum of Innocence”. By viewing objects as actors capable of creating meaningful social networks, I consider their use in the narration of personal and collective histories and their transformation as powerful symbols of a bygone era.

Implementation of high performance liquid chromatography coupled to thermal lens spectrometry (HPLC‑TLS) for quantification of pyranoanthocyanins during fermentation of Pinot Noir grapes
Lorena Butinar, Jelena Topič Božič, Natka Ćurko, Karin Kovačević Ganić, Branka Mozetič Vodopivec, Dorota Korte, Mladen Franko, 2020, original scientific article

Abstract: In this work high performance liquid chromatography coupled to thermal lens spectrometry (HPLC-TLS) was applied for monitoring of vinylphenolic pyranoanthocyanins formation during the fermentation of Pinot Noir wines. Vinylphenolic pyranoanthocyanins are wine pigments, present in low concentrations, but very important for wine colour stability. Fermentation process was conducted with four different yeast strains, used as starters, either in sequential fermentation of non-Saccharomyces with S. cerevisiae yeast or as single fermentation with S. cerevisiae yeasts in order to test the applicability of developed method for monitoring of selected compounds in real wine fermentation experiments. The developed HPLC-TLS method showed higher sensitivity compared to HPLC coupled to diode array detection (DAD) technique for particular wine colour compounds. Obtained limits of detection (LODs), were 6- and 22-times lower in comparison to HPLC–DAD in gradient and isocratic elution mode, respectively, whereas limits of quantification (LOQs) 5 and 18-times lower. Lower LODs enabled earlier observation of vinylphenolic pyranoanthocyanins formation during fermentation (already at day 7) in the case of HPLC-TLS method in gradient mode, while by using HPLC–DAD in gradient elution mode the formation of vinylphenolic pyranoanthocyanins was noticed only after 12 days of fermentation.

Bora wind effects on common structures in the Vipava valley
Marija Bervida, doctoral dissertation

Abstract: Strong and gusty north-east wind called Bora is common in south-west regions of Slovenia, as well as along the Adriatic coast. Its intermittent behavior, related to variable strength, frequency and duration, has brought out scientific curiosity for decades. Bora affects human life and causes problems for structures built in Bora affected areas. In Slovenia, Bora is the strongest in the Vipava valley. The motivation for this research is the need to evaluate Bora wind effects on structures, commonly found in the Vipava valley region, using a high resolution computational fluid dynamics (CFD) modeling approach. To date, there are several experimental and computational constraints for accurate representation of Bora in a CFD model, therefore, the main aim of this dissertation is to build foundations for Bora wind simulations using CFD and its method of finite volumes. The dissertation incorporates the analysis of experimental measurements of Bora wind, as well as numerical modeling studies. Vertical mean wind speed profile characteristics of Bora were analyzed based on experimental measurements at Razdrto just above the Vipava valley. The obtained results contributed to the choice of Bora mean wind profiles applied at the inflow of computational models. Guidelines regarding the choice of the associated wind profile parameters were given and a new relationship between these parameters was found. As orographic barriers to the north of the Vipava valley are known to give rise to Bora and to define the specific properties of the Bora flow, numerical modeling studies were in the first place focused on the implementation of the real-scale complex terrain into a CFD model. Simulation of wind flow over orographic barrier in Vipava valley was performed using Raynolds averaged Navier-Stokes approach, providing a first estimation of the flow field over a small hill of Zemono. As resolving the turbulence characteristics of Bora is very important for the estimation of wind loads on structures, modeling studies converged towards a more appropriate approach - Large eddy simulations (LES). A crucial step in setting up an accurate LES is the generation of appropriate inflow, which was investigated for the case of atmospheric boundary layer (ABL) flow. The synthetic method PRFG^3 for the generation of unsteady inflow was tested and adapted as a source of an ABL flow with desired turbulence flow properties. Based on its performance, in particular on adequate reproduction of target turbulence intensities and length scales, it was found that PRFG^3 method may be used to generate velocity inflow with desired turbulence properties in LES. Finally, simulations of wind flow coming from Bora direction over the Vipava valley were performed with the aim to depict the effects of underlying orography on the flow within and above the valley. Modeling results were found to be comparable with the results of lidar based remote sensing of vertical atmospheric structures within and above the valley.

Abstract: Human Papillomavirus (HPV) infection is the causative agent for the invasive cervical cancer and its precancerous lesions, furthermore, there are growing evidences of HPV being a relevant factor in other anogenital cancers as well as head and neck cancers. Most sexually active women become infected with HPV at least once in their lifetime, but less than 10% of women becomes persistently infected, and it is precisely the persistent infection that contributes to the development of cervical cancer. The preventive effect of cervical cancer screening largely depends in the high women participation and coverage; indeed, a large number of cervical cancers diagnoses normally arise among under-screened and unscreened women. Increase in the screening coverage is essential to improve the effectiveness of cervical screening programmes. The main purpose of this PhD project was to solve some of the most relevant problems in the cervical cancer screening programmes, as the increase of cost-effectiveness and the amelioration of the screening coverage. My work was focused on the development and validation of the first Ulisse BioMed S.p.A. product, the HPV Selfy™ test, an innovative PCR-based kit for the direct detection and genotyping of 12 high-risk HPV types (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58 and 59) and 2 possible/probable high-risk (66 and 68), specifically optimized for the analysis of self-collected vaginal specimens. The core of this innovative test is based on high-resolution melting (HRM) analysis, a recently developed technique for fast, high-throughput post-PCR analysis of variance in nucleic acid sequences, that characterizes the amplicons by studying thermal denaturation of double-stranded DNA. Based on this approach and through the design of different HPV type-specific primer pairs and the development of a specific master mix, unique melting peaks in a single fluorescence channel were obtained, allowing the multiple detection and genotyping of 14 HPV types in a single PCR well. Three different clinical studies have been carried out to validate the assay on the vaginal self-collected samples with truly amazing results regarding the assay’s performance, but also for self-sampling acceptability by women. Moreover, data collected in these studies suggest a future possible use of this test for the hard-to-reach women, as an alternative of the conventional clinician-collected sample, in order to increase the cervical cancer screening coverage.

Chemical Instability of an Interface between Silver and Bi2Se3 Topological Insulator at Room Temperature
Katja Ferfolja, Matjaž Valant, I. Mikulska, Sandra Gardonio, Mattia Fanetti, 2018, original scientific article

Abstract: Understanding an interaction at an interface between a topological insulator and a metal is of critical importance when designing electronic and spintronic devices or when such systems are used in catalysis. In this paper, we report on a chemical instability of the interface between Bi2Se3 and Ag studied by X-ray powder diffraction and electron microscopy. We present strong experimental evidence of a redox solid-state reaction occurring at the interface with kinetics that is significant already at room temperature. The reaction yields Ag2Se, AgBiSe2, and Bi. The unexpected room-temperature chemical instability of the interface should be considered for all future theoretical and applicative studies involving the interface between Bi2Se3 and Ag.
