Rad je rezultat istraživanja na projektu Pravnog fakulteta Univerziteta u Kragujevcu: „Usklađivanje pravnog sistema Srbije sa standardima Evropske unije”, koji se finansira iz sredstava Fakulteta. ; This scientific work analyzes the concept of human rights under the challenges of the green transition in Europe. The right to a healthy environment receives its full affirmation through adoption European Green Deal. In order to alleviate the consequences of the imbalance and mismatch between the development of society and the preservation of nature, the European Union is intensifying normative activity in the field of environmental protection. The Republic of Serbia as a candidate for membership in The European Union is obliged to make its policy and legal the system adapts to such trends. This question becomes especially important after our country's accession to the Green Agenda for the Western Balkans. New social conditions created under the influence of green ideas, offer new directions for the development of the corpus of human and minority rights. ; Published

Great challenges are ahead of researchers when they plan to sustainably meet the needs of people, more than 10 billion, using the scarce resources of food, water and energy. The ability to meet the needs at the local level is critical because it is expected a significant population growth in less developed areas of the world. Compliance with the provisions of the scientific ecology and the introduction of cutting-edge achievements in nanotechnology opens up a number of changes in agricultural production. Yields can be doubled while reducing the usage of pesticides and GMOs. Political describe the environmental objectives given unwarranted importance of various types of repeatable source of energy from the sun, wind and geothermal over to bio raw materials. Most queries originating from the time periodicity and the local availability of such sources of energy. Today's electrical solar panels have a theoretical efficiency of 33%, with the actual efficiency about 15%. According to scientific ecology they prevent reflection of solar radiation and heat the environment and act completely anti-ecological. Combining energy sources is a necessity for the future, although it is more expensive. Ecological is quite normal that all complex systems in addition to the advantages of having a number of shortcomings. ; https://www.researchgate.net/publication/329530344_INTRODUCTION_OF_SCIENTIFIC_ECOLOGY_TO_ALL_AREAS_OF_AGRICULTURAL_MECHANIZATION_UVODENJE_NAUCNE_EKOLOGIJE_U_SVE_OBLASTI_POLJOPRIVREDNE_MEHANIZACIJE ; Published

Wastewater treatment plants contribute to the removal of pollutants from wastewater following the norms and regulations on the quality of the wastewater and therefore are an indispensable part of wastewater treatment and environmental protection. Each stage of wastewater treatment consumes a significant amount of energy. The need to meet rapid population growth and stricter conditions in terms of effluent quality requirements has led to an increase in energy consumption in wastewater treatment plants. Energy consumption is a bottleneck in wastewater treatment plants and, as the number of these plantsin the world increases, the issues of reducing energy consumption and energy efficiency are beginning to attract attention. It also contributes to the cost increase in wastewater treatment plants. Analysis and prediction of energy consumption are key factors for energy savings. Energy consumption in wastewater treatment plants is affected by many factors. However, information on energy consumption and potential for energy recovery/production and energy efficiency in wastewater treatment plants remains very limited. This paper reviews the literature and analyzes the energy consumption in these plants and the possibility of increasing the energy efficiency of these plants through the use of renewable energy sources and energy recovery from the plant itself. ; Published

The core of the dissertation is to improve energy efficiency of small hydropower plants (SHPPs). The focus is to solve the problems of (1) decreased electricity production during low water flows and (2) inadequate functioning of multi-chamber settling basins because of an uneven flow distribution among the chambers. The latter problem has been solved by an original methodology, which is an upgrade on the traditional usage of CFD and analytical models. The methodology is among the scientific contributions that are:  a method for the iterative finding of a technical solution by the use of a CFD and an ancillary analytical model, which is a guide for a complex and slow CFD model towards an optimal geometry;  a method for the determination of local pressure drops (minor losses) for complex geometrical shapes with multi-dimensional flow patterns using: CFD simulations, regression analysis, and indirect validation;  the application of modern software for the design, optimization, modeling, and modernization of SHHPs.  a novel solution for simultaneous equalization of flows among the chambers of a multi-chamber settling basin and the dissipation of turbulent kinetic energy. These results were implemented on a case study, which includes two cascade SHPPs with a common side water intake and nominal installed capacities of 1.220 MW and 1.327 MW. The solving of both problems resulted in technical solutions for:  the determination of an optimal configuration under existing conditions (gross head, turbine types, pipeline diameters) by the use of new turbine(s) and independent or coupled operation of two run-of-the-river SHPPs;  the equalization of flows among the chambers of a multi-chamber settling basin and the dissipation of turbulent kinetic energy by the use of: (a) pillars with vanes in a common inlet zone and (b) sluice gates with tranquilizing racks. The solution of the (1) problem increased the electricity production by 4.8% and the solution of the (2) problem reduced the total loss by 8%. The results are ...

The art of Francis Bacon is positioned as a London school of figurative painiting of the second half of the twentieth century, and as such it is the most direct reflection of the post-war traumas of the Nazi regime that befall Europe and the world. It was exactly at the time, at the intersection of social, economic, scientific and technological and cultural practices, that a Western neoliberal order was formed. It is a sample or archeological/historical layer also studied by post-structuralists Michel Foucault, Gilles Deleuze, Felix Guattari. This text is an attempt of explication of certain links in the opinion that connect the painting of Francis Bacon and the theory of post-structuralism, which are focused on the issues of development of biopower within certain historical sites. Namely, post-structuralists realise that archeological layers are volatile historical categories, and each of them is an independent social and cultural creation. Bacon authentically connects these historical layers through his visual language, referring to older painters such as Velasquez, Rembrandt, Ingres or Van Gogh. Thus Bacon re-examines the status of the subject (conceptualises life by the powers of death using human body) and its liberties both in liberal and in neoliberal societies. ; Published

U radu je razmatrana implementacija toplotne pumpe tipa vazduh-voda za zagrevanje domaćinstva kao zamena za električni kotao. Predložena je metodologija za utvrđivanje potrošnje energije za zagrevanje objekta na osnovu prikupljenih podataka sa računa za električnu energiju i simulacija softverom za proračun gubitaka toplote na osnovu građevinske fizike objekta. Razvijena metodologija je analizirana na studiji slučaja. Rezultati su pokazali da je u slučaju analiziranog objekta moguće ostvariti uštedu u potrošnji električne energije od oko 60%. U finansijskom smislu, uzimajući u obzir tarifni sistem naplate moguće je očekivati smanjenje računa za električnu energiju i do 3 puta. Prost period povraćaja investicije je za analizirani slučaj oko 4 godine. This paper focuses on the implementation of air-water heat pumps used to provide heating for households instead of electric boilers. The paper proposes a methodology for determining the quantity of energy used for heating based on the data collected from electricity bills. In addition, the simulations conducted in a selected software can provide insight into the amount of energy loss based on the constructional characteristics of an object. The proposed methodology was tested through a case study. The results indicate that the selected household can save about 60% of electricity currently consumed. Financially speaking, it is reasonable to expect that the electricity costs can be reduced by three times and that the payback period of the investment would be about four years for this household. ; Published

Smanjenje emisije ugljen-dioksida i postizanje klimatske neutralnosti jedan je od glavnih izazova današnjice. S tim u vezi, prelazak sa fosilnih goriva na obnovljive izvore energije predstavlja cilj energetskih planiranja u različitim zemljama širom sveta. Kao odgovor na globalnu težnju, ali i na pariski sporazum, Republika Srbija je predstavila nacrt dokumenta „Integrisani nacionalni energetski i klimatski plan, za period od 2021. do 2030. godine, uključujući perspektivu do 2050“. Međutim, kada je reč o dugoročnom energetskom planiranju na državnom nivou, važno je osvrnuti se na gradove, jer se u njima, na globalnom nivou, koristi više od 75% primarne energije. Postizanje klimatski neutralnih gradova zahteva vreme, kao i opsežnu analizu energetskog potencijala. Cilj ovog rada je sprovođenje SWOT analize planiranja budućeg energetskog sistema, na primeru grada Kragujevca. Rad prikazuje sve prednosti i snage na putu smanjenje ugljeničnog otiska, ali i sve nedostatke i pretnje sa kojima se zainteresovane strane mogu suočiti. Sprovedena SWOT analiza je urađena u skladu sa svim dostupnim podacima i, kao takva, rezultira prikazivanjem sadašnjih energetskih potreba i uvidom u moguće buduće pravce energetskog razvoja Grada Kragujevca, uz osvrt na nacionalnu i lokalnu energetski politiku. Reducing carbon dioxide emissions and achieving climate neutrality is one of the main challenges nowadays. In this regard, the transition from fossil fuels to renewable energy sources is the goal of energy planning in various countries worldwide. The Republic of Serbia announced a draft Integrated National Energy and Climate Plan of the Republic of Serbia for the period 2030 with the projections up to 2050, in response to both the global aspiration and the Paris Agreement. Yet, since cities utilize more than 75% of primary energy globally, they should be considered when it comes to long-term energy planning at the national level. Achieving climate-neutral cities requires time and extensive analysis of energy potential. This paper aims ...
