Geotehnički efekti razaranja komunalnog otpada različitim postupcima zbijanja
Jovana M. Janković Pantić (2022)Odlaganje otpada na komunalne deponije predstavlja osnovni način zbrinjavanja otpada u Srbiji. Kako bi se prostor za deponovanje materijala racionalno koristio potrebno ga je svakodnevno zbijati sa unapred definisanom količinom vode koja se dodaje. Dobro zbijeni komunalni otpad zauzima manju zapreminu i omogućuje sigurnije skladištenje, pa je korisno prethodno laboratorijski odrediti parametre zbijanja: maksimalnu suvu zapreminsku težinu (dmax) i optimalnu vlažnost (wopt). U Srbiji do sada nisu određivani parametri zbijanja, dok je u svetu primenjivana standardna metoda (Proktorov opit) ...Jovana M. Janković Pantić.

Početak njihove aktivnosti vezuje se za rotaciju tektonskih jedinica Karpato-balkanida (Dacia Mega Unit) oko rigidne Mezijske jedinice. Aktivnost ovih transkurentnih raseda je akomodirala ovu rotaciju, pa se smatra da je kumulativno kretanje duž Timočkog raseda tokom perioda njegove aktivnosti bilo do 100 km.

A necessary and sufficient condition for an algebraic integer to be a Salem number
Dragan Stankov (2019)We present a necessary and sufficient condition for a root greater than unity of a monic reciprocal polynomial of an even degree at least four, with integer coefficients, to be a Salem number. This condition requires that the minimal polynomial of some power of the algebraic integer has a linear coefficient that is relatively large. We also determine the probability that an arbitrary power of a Salem number, of certain small degrees, satisfies this condition.Algebraic integer, the house of algebraic integer, maximal modulus, reciprocal polynomial, primitive polynomial, Schinzel-Zassenhaus conjecture, Mahler measure, method of least squares, cyclotomic polynomialsDragan Stankov.

Strategic Environmental Assessment in the Application of Preventive Protection for Wind Farm Noise—Case Study: Maestrale Ring Wind Farm
Determining the spatial position of wind turbines is the initial and most important phase in the development of a wind farm project. In this sensitive phase, all potential problems that may arise in the later stages of project development should be prevented by means of spatial and urban planning instruments.

Business Models for Small-scale Biomass Projects Development
Biomass is recognized as the most promising renewable energy source in Serbia. The share of biomass in Serbian final energy consumption is over 10%, but mostly related to traditional use in stoves and ovens. One of the main obstacles for wider implementation of contemporary biomass facilities is the inexperience of consumers and stakeholders in the implementation of “innovative” business models, especially in the cases of small-scale projects. In this paper, three different business models (public utility company, energy cooperative ...... self-government unit recognizes the environmental significance, as well as the economic and social potential of the biomass project in some of the local communities, but lacks sufficient financial, technical and human capacities to implement such a project, local self-government unit could implement ...

Clockwise vertical-axis rotation in the West Vardar zone of Serbia: Tectonic implications
The Vardar-Tethyan mega-suture between the Eurasian and Adria (Gondwana) margins comprises remnants of oceanic lithosphere of Neotethys and distal parts of the adjacent continental margins including unconformable Late Cretaceous sedimentary cover and Cenozoic igneous rocks of post-obduction age. This study provides kinematic constraints for displacements and rotations affecting the Serbian part of the West Vardar and Jadar-Kopaonik units after the closure of the Neotethyan (= Sava) Ocean. The targets of the paleomagnetic research were Late Cretaceous sediments representing an ...... lithosphere (obducted ophiolites and ophiolitic mélange), but also distal parts of the ancient Gondwana margin (in the Serbian segment, the Drina– Ivanjica, the Jadar–Kopaonik units below the obducted West Vardar ophiolites, Fig. 1), and post-obduction sedi- mentary and igneous rocks.
