Prvi nalazi repatih vodozemaca (Urodela) u pleistocenskoj pećinskoj fauni Srbije; još jedna kockica u slagalici
Fosilna fauna pleistocenskih pećina odslikava sastav faune njihove okoline. Najčešće se u njima naleze ostaci krupnih sisara ledenog doba koji su je koristili kao stanište. Uz njih česti su i ostaci drugih sitnih kičmenjaka kao što su sitni sisari, ribe, vodozemci, gmizavci i ptice. Ostaci sitnih kičmenjaka u većini slučajeva u pećinu dospevaju kao plen grabljivica (ptice i sisari) ali je manji broj njih pećinu koristio i kao sklonište ili stanište.

Analiza sistema odvodnjavanja površinskog kopa Drmno od podzemnih voda sa severnim savršenim ekranom
Izrada nesavršenog ekrana do drugog sloja uglja na površinskom kopu Drmno, pored zadržavanja postojećih standardnih metoda odvodnjavanja od podzemnih voda linijama bunara, predviđena je poslednje decenije u celokupnoj rudarskoj projektnoj dokumentaciji. Iz objektivnih i subjektivnih razloga njegova realizacija nije ostvarena do danas. U međuvremenu je, uz dodatna geološka istraživanja i promenu dinamike i parametara sistema površinske eksploatacije, došlo do određenih značajnih prostornih promena geoloških i rudarskih uslova u eksploatacionom polju. Ovo je omogućilo preliminarno inoviranje pristupa procesu i konceptu ...Tomislav Šubaranović, Dušan Polomčić, Vladimir Pavlović.

Sitni, ali bitni: uloga sitnih sisara, herpetofaune i mekušaca u rekonstrukciji pleistocenskih paleosredina
Fosilni ostaci životinja i biljaka imaju važnu ulogu u rekonstrukciji pleistocenskih paleosredina. U ovom radu opisan je značaj tri grupe životinja: sitnih sisara, herpetofaune I mekušaca. Mada je za rekonstrukciju važan sastav čitave asocijacije, nalasci pojedinih vrsta mogu biti dovoljno indikativni da otkriju tip staništa ili klimatske uslove. Posebnu teškoću pri rekonstrukciji paleosredina u Srbiji predstavlja činjenica da klimatske promene na Balkanskom poluostrvu nisu bile tako oštre kao u srednjoj i zapadnoj Evropi, pa ne postoji drastična razlika u ...... of the Science Fund ofthe Republic of Serbia, nuamber 7746827. 52 III KONGRES GE0LOGR BOSNE I HERCEGOVMINE SR MEBUNRRODNIM UČEŠĆEM References: 1. 10. 11. 12. 13 14. 15. 16. 17. 18. 19.

Model za optimizaciju graničnog saržaja metala u rudi u funkciji dugoročnog planiranja površinskih kopova
Daniel P. Kržanović (2016-06-14)Optimizacija graničnog sadržaja metala u rudi jedan je od osnovnih koraka u planiranju i dizajniranju površinskih kopova i ima za cilj postizanje maksimalne neto sadašnje vrednosti (NPV).

Quantitative landslide risk assessment in the city of Tuzla
In the climate-changing conditions, geological environment interacts more dramatically with the urban fabric than before. The urbanization is expansive and more aggressive than before, but so are the weather extremes and long-term climate trends. In effect, many processes which can be triggered by either side, nature or engineering, are becoming more pervasive than before, and such is the case with landslides. Dealing and managing landslides requires few crucial steps, starting from collecting data on landslide location and typology – ...... implemented by HEIS Sarajevo, URBIS Banja Luka and IBIS Engineering, Banja Luka.

Life Cycle Assessment of Individual Wood Biomass Heating Systems in Households
The use of solid fuels (wood biomass and coal) for heating of households continues to be common practice within European countries. Solid fuel combustion in households contributes more than 46% to total emissions of fine particulate matter. In this study, a life-cycle assessment (LCA) of firewood-based and pellet-based heating systems is performed. These two systems represent two different types of individual wood biomass heating systems. In the case of the firewood-based heating systems, it is analyzed a typical stove ...... INTRODUCTION Heating in households has a significant share of final energy consumption in most of the European countries. In EU households, heating and hot water alone account for around 79% of total final energy use [1], [2]. The use of solid fuels for heating of households continues to be common practice ...

Analysis of the exhaust emissions inventory from auxiliary mining machines
Stevan Đenadić, Aleksandar Mirković, Jovana Mitrović, Filip Miletić, Predrag Jovančić, Dragan Ignjatović (2023)Open-pit coal mines are equipped with a large number of mining machines and vehicles with diesel engines. Due to common daily operation of these machines and vehicles large amounts of exhaust gases which contain numerous pollutants are emitted into the atmosphere. The demand to reduce air pollution induced the activities in developed countries to map and calculate all gases emitted by industries to formulate and select adequate preventive activities. In collaboration with machine manufacturers, emission standards for off-road machines ...Stevan Đenadić, Aleksandar Mirković, Jovana Mitrović, Filip Miletić, Predrag Jovančić, Dragan Ignjatović.
