Radiological and physico-chemical characterization of red mud as an Al-containing precursor in inorganic binders for the building industry
Ljiljana Kljajević, Miljana Mirković, Sabina Dolenec, Katarina Šter, Mustafa Hadžalić, Ivana Vukanac, Miloš Nenadović, 2021, izvirni znanstveni članek

Povzetek: The potential re-use of red mud in the building and construction industry has been the subject of research of many scientists. The presented research is a contribution to the potential solution of this environmental issue through the synthesis of potential construction materials based on red mud. A promising way of recycling these secondary raw materials is the synthesis of alkali-activated binders or alkali activated materials. Alkali-activated materials or inorganic binders based on red mud are a new class of materials obtained by activation of inorganic precursors mainly constituted by silica, alumina and low content of calcium oxide. Since red mud contains radioactive elements like 226Ra and 232Th, this may be a problem for its further utilization. The content of naturally occurring radionuclides in manufactured material products with potential application in the building and construction industry is important from the standpoint of radiation protection. Gamma radiation of the primordial radionuclides, 40K and members of the uranium and thorium series, increases the external gamma dose rate. However, more and more precedence is being given to limiting the radiological dose originating from building materials on the population these days. The aim of this research was to investigate the possible influence of alkali activation-polymerization processes on the natural radioactivity of alkali activated materials synthesized by red mud (BOKSIT a. d. Milići, Zvornik, Bosnia and Herzegovina) and their structural properties. This research confirmed that during the polymerization process the natural radioactivity was reduced, and that the process of alkali activation of raw materials has an influence on natural radioactivity of synthesized materials.

Christian-Muslim women in religious peacebuilding, breaking cycles of violence
Nadja Furlan-Štante, 2020, izvirni znanstveni članek

Povzetek: In a broader context, the main focus of this paper is the question of wom-en%s religious peacebuilding, which is understood in its widest sense, in terms of women%s active participation in building liberating theologies and societies. It is about the promotion of the full humanity of women. While elaborating this theme, the paper takes up Susan Brooks Thistlethwaite%s assertion that the %violence against women is the largest and longest global war.% Just peacemak-ing is very much an interfaith and interreligious work and should be placed as a crucial starting point of the urge for transformation of %violent% theologies and living everyday praxis. While women have been marginalised from peacebuild-ing generally, the emerging field of religious peacebuilding has been particularly challenging for women. The liberating theme of this paper is illumination of the ambivalence of invisibility and marginality of women in religious peacebuilding, good practices and future issues.
