Fractional flow reserve (FFR) is one of the clinical diagnostics meas- urements that are performed to assess the physiological significance of stenosis potentially present in coronary arteries. Virtual fractional flow reserve (vFFR) is an alternative non-invasive approach that consists of performing the 3D recon- struction of the patient-specific coronary artery and afterwards applying tech- niques of computational fluid dynamics (CFD) to obtain the vFFR value. Within this paper, a new ...

Tourism is the fastest-growing industry with an increasingly active participation in people's economic and social life. The tourism industry offers numerous opportunities for development in which entrepreneurs recognize the potential chances of developing new ideas and creating innovative products. In such a business environment a new concept of tourism companies appears, known as tourism entrepreneurship. It means a proactive orientation towards monitoring and recognizing new market trends a...

Tourism as an economic sector has the capacity to meet the diverse needs of different groups of tourists. Accordingly, tourism is an important factor in the development of areas where it exists and evolves. Holidays in rural areas, in the era of "fast life," are increasingly becoming an accepted form of tourism. The development of rural tourism is seen as a significant factor for the development of rural areas, the improvement of agriculture, crafts, and the preservation of the traditions and...

Tomato (Solanum lycopersicum L.) is one of the most important and widely cultivated vegetable crops worldwide, valued for its nutritional, energetic, and medicinal properties. The growing demand for sustainable agriculture has increased interest in organic and integrated production systems, which limit or eliminate the use of synthetic inputs. This study aimed to examine the content of microelements in tomatoes grown under organic and integrated production systems. Two tomato types (cluster a...

As the main factors for the increase agricultural productivity in the 20th century are considered insecticides. However, many insecticides are toxic not only to the target species, but also to non-target organisms, mainly due to physiological similarities between them. In recent years, numerous ecotoxicity studies have been carried out on aquatic and soil organisms. Among terrestrial invertebrates, Lumbricidae are one of the most important groups. They have great ecological, economic and soci...

This paper examines the concept of space in the novel Vladimir from the Strange Story (Vladimir iz čudne priče) by Gordana Timotijević. The analysis results show that the narrative structure of the novel is built by duplicating fictional worlds through the insertion of stories within stories. There is also an intertwining of stories and a crossing of boundaries from one fictional space to another, as well as an intersection of different temporal perspectives and a shifting of roles between th...

Development of precision agriculture, particularly through the use of sensory technologies, has had a significant impact on livestock farming worldwide. This study examines the use of sensory technologies in Serbian livestock farms in comparison to the EU and other developed European countries. Primary research question is how the use of sensory technologies in the Serbian livestock production compares to the EU and what factors influence these differences. To answer this question, a com...

In modern industrial production, due to rigorous working conditions, machine parts frequently fail or wear out, leading to production downtime and financial losses. When a machine part becomes damaged, there are two options: replace the worn part with a new one or repair the damaged part through welding. Although purchasing a new part initially seems like a simpler and more reliable solution, many large industrial systems today opt for the regeneration of damaged components. This choice is d...

This paper explores the application of multi-agent systems (MAS) in an educational environment through the modeling and simulation of a flexible manufacturing system (FMS). The focus is on developing models and programming agents for managing CNC machines, a robot with a peripheral axis, and part manipulation. Students are guided through recommended exercises aimed at optimizing operations and handling parts. Using the Python programming language, students develop code that enables both simu...
