Activity concentrations of 226Ra, 232Th and 40K in some building materials used in Montenegro were measured by the gamma spectrometry (HPGe spectrometer and multidetector spectrometer PRIPYAT-2M), and the results are presented in this paper. Levels of the radionuclides in analyzed sand, cement, brick, gypsum, ceramic tile, as well as marble and gra...

Over 22% of the whole Serbian population represent the elderly, i.e. the people aged 65 and above. Accordingly, national policies had to be adjusted to this growing demographic group. However, there is a gap relating territorial aspects of ageing in Serbia, crucial for the mobility of the elderly people. An umbrella document – the National st...

Virtual tours of monuments become more and more a vital part of the promotion of the culture and therefore tend to be one of the main areas of study in the field of cultural heritage. These representations offer users the chance to tour in areas located far away. In order to create accurate and correct 3D representations of the monument, geometric ...

Composite steel and concrete structures are widely used in modern civil engineering due to their structural efficiency and economic performance. However, conventional composite systems limit the possibility of full structural disassembly and reuse of steel structure elements and composite slabs, which is increasingly important in sustainable constr...

Fish passages represent a key engineering and ecological measure for restoring the longitudinal connectivity of watercourses disrupted by hydraulic structures. This paper presents the conceptual design of a nature-like fish passage at the Djerdap 2 hydropower plant on the Danube River. The study includes route definition, hydraulic sizing under com...

Architectural education has often advanced at a slower pace than the rapid transformations of spatial practice and society. Within this imbalance, the architectural workshop emerges as a condensed yet intensive format of experimentation, providing a distinctive environment for testing pedagogical approaches. This study critically examines the works...

Abrasion resistance is a critical durability parameter of foamed concrete applied in floor screeds and wear - exposed surface layers. Owing to its cellular structure, abrasion performance depends on bubble morphology, including size, distribution and uniformity. This paper presents an experimental study combining high - magnification microscopy wit...

This paper examines the development of forms in memorial architecture, from prehistoric structures to abstract monuments. It demonstrates how basic patterns such as circular structures, pyramidal forms, and simple geometric shapes have established enduring principles in memorial design. Over time, these forms have evolved under the influence of rel...
