Geotechnical effects of municipal solid waste destruction with different compaction methods
Jovana M Janković Pantić, Dragoslav R Rakić, Irena G Basarić Ikodinović, Tina D Đurić, Gordana Hadži-Niković (2022)Disposal of waste in municipal solid waste landfills is the only way of waste disposal in Serbia, with daily compaction and covering with soil material. Due to less space for the construction of new landfills, it is necessary to use their maximum capacity. Well-compacted municipal solid waste takes up less volume and enables safer storage, so it is useful to previously determine the compaction parameters in the laboratory: maximum dry unit weight (γdmax) and optimal water content (wopt). In ...Jovana M Janković Pantić, Dragoslav R Rakić, Irena G Basarić Ikodinović, Tina D Đurić, Gordana Hadži-Niković.

Стање квалитета амбијенталног ваздуха на подручју града Панчева
Александар Маринковић (2024)Квалитет ваздуха је кључни фактор за здравље људи и очување животне средине. У овом завршном раду анализирано је стање амбијенталног ваздуха на територији града Панчева како би се сагледали извори загађења, ПЛН мониторинга и изазови у погледу квалитета ваздуха са којима се суочавају сви становници. Кроз примену савремених метода праћења, идентификовани су главни извори загађења и анализирана је дистрибуција загађујућих материја у урбаном окружењу.Праћењем концентрације загађивача као што су честице PM10, PM2.5, сумпор-диоксид (SO2), азот-диоксид (NO2) и други, ...... 3arabyjyha Marepuja Mecra (MM) 1. |Ilapa/{ymaga (a),(Mc) SO», BTX, NO:, NO, NOx Ox, CoO 2.

Testing the energy value of different types of coal by the method of active thermography
In this paper, coal thermograms are presented and analyzed in order to determine their energy value. Two types of coal of different categories, brown and lignite, were selected for active thermographic imaging. The tested coal samples were processed before measurement so that they are similar in dimensions and have two plane-parallel smooth surfaces. The test samples were "primarily" heated under the same conditions and the process of their cooling was monitored by a thermal camera. "Then" they were cooled ...Stevan Đenadić, Ljubiša Tomić, Vesna Damnjanović, Predrag Jovančić, Dragutin Jovković.

Development and Application of Methodology for Quantification of Overbreaks in Hard Rock Tunnel Construction
A methodology for determining overbreaks in hard rock tunnel construction using the drill-and-blast technique is presented in this paper. The methodology was developed for and applied to crystalline medium- to thick-bedded limestone, but it can be used in any jointed hard rock mass. Overbreaks are inevitable in hard rock tunnelling in a low-confinement environment (shallow tunnels up to several hundred meters deep) as a result of wedge failures along unfavourably oriented discontinuities caused by blasting. It is widely accepted ...hard rock, drill-and-blast, geological overbreak, technological overbreak, stability criterion, discontinuity orientation, tunnel constructionZoran Berisavljević, Dragoljub Bajić, Vojkan Jovičić.

Geotechnical zoning of the terrain along the first section of E-80 highway in Serbia – SEETO route 7
Part of E-80 highway that passes through Serbia (from the city of Nis to the administrative border Merdare) is 77 km long. The highway is divided into two sections: the first from Nis to Plocnik (39.4 km long) and the second from Plocnik to the administrative border with Kosovo. The route is designed through a typical plain and hilly terrain in which different geological units are dominant: crystalline schists, neogene sediments of foothills and quaternary sediments in the valley ...... Pliocene coarse grained complex is saturated, and larger number of active wells is registered in the zone of outlet portal of the tunnel „Bozurna“, so the permanent influence of groundwater on the tunnel is expected (it is confirmed by observations in piezometers). Older Neogene complex has ...
