1. Nutritional quality and safety of the spirulina dietary supplements sold on the Slovenian marketJasmina Masten, Marta Jagodic Hudobivnik, Marijan Nečemer, Katarina Vogel-Mikuš, Iztok Arčon, Nives Ogrinc, 2022, izvirni znanstveni članek Opis: The microalgae Spirulina may be a popular dietary supplement rich in essential nutrients
and vitamins, but oversight of the supplement industry, in general, remains limited, and increasing
incidents of adulteration, misbranding, and undeclared ingredients together with misleading claims
create potential risks. In response, this study characterized the elemental, amino acid and fatty acid
content of commercially available Spirulina supplements in Slovenia using EDXRF, ICP-MS and
GC-MS and compared the results with their nutritional declaration. The gathered data confirm that
Spirulina supplements are a good source of calcium (0.15 to 29.5% of RDA), phosphorous (3.36–26.7%
of RDA), potassium (0.5 to 7.69% of RDA) and selenium (0.01 to 38.6% of RDA) when consumed
within recommended amounts. However, although iron contents were relatively high (7.64 to 316%
of RDA), the actual bioavailability of iron was much lower since it was mainly present as the ferric
cation. This study also confirms that pure Spirulina supplements are a good source of essential
and non-essential amino acids, and !-6 but not !-3 polyunsaturated fatty acids. The presence of
additives resulted in significant variation in nutrient content and, in some instances, lower product
quality. Moreover, a high proportion (86.7%) of inappropriate declarations regarding the elemental
content was observed. Overall, the study conclusions underline the need for a stricter control system
for Spirulina-based supplements. Ključne besede: Spirulina, microalgae, cyanobacteria, elements, toxic elements, amino acids, fatty acids, authenticity, safety, quality Objavljeno v RUNG: 24.03.2022; Ogledov: 2400; Prenosov: 0 Gradivo ima več datotek! Več... |
2. The Circular Economy in Adaptive Reuse: Respecting Authenticity and IntegrityMarco Acri, Saša Dobričić, Jukka Jokilehto, 2019, objavljeni znanstveni prispevek na konferenci Opis: One of the main topics of discussion and research at present in the building sector is related to the principles of circular economy in a new global scenario of resilience and sustainability. Given that most of European urban areas and landscapes are considered as cultural, it derives that the circular economy should be also applied to the actions and processes of conservation and valorisation, giving thus new emphasis on the concept of adaptive reuse. Thus, it is not merely an issue of retrofitting historic buildings to respond to energy efficiency parameters, or to adapt them for the climate change threats, but much more: it is about rethinking adaptive reuse of cultural heritage (adaptive in both directions) within and overall sustainable process which intakes reflections on materials, techniques, technologies, praxes, but also policies, businesses, management and governance. This is the effort of the CLIC project, Circular Models leveraging investments in Cultural heritage adaptive reuse, in the Horizon2020 research framework, where the University of Nova Gorica is a partner.
This new approach in a global market economy perspective is strongly looking backwards to the traditional building site mechanisms, techniques and procedures, as matured in logistic and technological constraints. In history though, prior of the enforcing of the conservation theory principles, the aspects of authenticity and integrity were not a reference for the builders as the materials and the technologies were usual, repetitive for centuries, while today they are essential criteria for conservation and reuse. But what does it mean today looking at circular models in adaptive reuse? Adaptive reuse refers to the need to adapt cultural heritage to new needs and uses, but circularity ask also to adapt to the cultural heritage peculiarities and fragilities. May this mean we have an additional ally for the preservation of the integrity and the authenticity, as well as for a new wave in preservation of objects, urban and cultural landscapes?

3. RE-CONCEPTUALIZATION OF THE CONSERVATION THEORY FOR THE MANAGEMENT OF ARCHAEOLOGICAL HERITAGEUsman Ali, 2017, doktorska disertacija Opis: ver the last few decades, the concept of “authenticity” has commonly been used as a criterion for heritage conservation and management in various regions around the world. In 1994, ICOMOS adopted the Nara document on Authenticity as an international recommendation to draw the attention of policy and decision makers on the values of cultural heritage, stressing on interdisciplinary of approaches. Interdisciplinary research of heritage studies includes analysis and evaluation methods to redefine the theories and methodologies of heritage preservation and management in different contexts. But, when dealing with Archaeological Heritage Management, various difficulties emerge in the adoption of prescribed criteria for heritage conservation and management.
The aim of this research is to examine and evaluate the compatibility and potential adaptation of these significant criteria from the Heritage International practice (I.e. UNESCO), including the spheres of law and philosophy, in the Management of Archaeological Heritage. Consequently, this dissertation is articulating according to the following concepts:
1. UNESCO already prescribed parameters and criteria of conservation and management of cultural heritage, but their full applicability on Archaeological Heritage Management should be verified;
2. The level of similarities and differences between Cultural and Archaeological Heritage in the conservation and management process should be discussed to highlight potential new research channels;
3. Is the adoption of the concept of Authenticity as a criterion, prescribed in UNESCO Operational Guideline, compatible enough to be applied to the Management of Archaeological Heritage or not?
4. Archaeological practice as a source of information provides various data and parameters. Are these attributions determining the management?
This dissertation concludes that thematic divisions of heritage studies foster and formulate various models and concepts (implicitly and explicitly), which determine many substantial criteria and integrated factors for the sustainability of archaeological heritage. These criteria and factors give

importance to the common theoretical and methodological research in archaeological heritage conservation theory and practice.

4. Building the shared dimension of the rural landscape: tools, principles and methods : An integrated approach to conservation and management of the rural landscape in Venice and its LagoonCaterina Groli, 2016, doktorska disertacija Opis: This research investigates the rural landscape of the lagoon of Venice and its surrounding territory focusing on the forms of exploitation of its natural resources, the transformations that occurred throughout the course of history and the consequent formation of its primary economical sector.
New economic sectors, new agricultural policies and other spatial and sectorial drivers transformed the primary sector itself which changed and adapted its productive schemes to the main economic patterns, heavily affecting the former rural asset of the landscape of the lagoon by changing its demographic, economic activities and land use practices.
The study carries out a systematic and detailed analysis of all economic, cultural and social features that have interacted and impacted this specific landscape, relying mainly on the comparison of historical and current land-use maps through three different historical spans: 1823-1840 (pre-industrialization phase), 1933-1966 (industrializing process, considered as a determining factor of the transformation of this landscape) and 2013 (present post-industrialized condition). The maps, combined with relative data, are compared with the aid of the Geographical Information System (GIS) computer software. As a result, a set of new maps has been obtained, which point out the historical landscape permanencies, defined through in situ surveys on the territory. A multitude of other archival documents from direct and indirect sources have been examined in order to build up a sound and detailed socio-economic context and the overall historical background.
Resources, goods and services provided by the rural landscape and its development are an important part of regional and EU policy instruments and also an essential factor of identity and growth for local communities. The consumption of resources, their availability and maintenance over time and accessibility through property regulations are all factors that shape the common and public dimension of the rural landscape, which represents another study challenge of this work.
This study proposes the establishment of the rural park of the lagoon of Venice, through the implementation of the multi-functional role of agriculture, for the fulfilment of two fundamental conditions of the peri-urban rurality: the need of safeguarding the landscape and its significance, by preserving the authenticity and integrity of the rural characters and the dynamism of the primary sector, which is strictly related to the survival of the rural landscape.
