Tipizacija mostova za autoceste
The procedure for typification of motorway bridges is described. It is emphasized that typical bridges for new Croatian motorways are designed in such a way to enable standardization and simplification of design and construction of a great number of bridges on these roadways. The procedure is based on the fact that the design work takes into account Croatian and foreign experiences, guidelines and standards, in order to achieve economic benefits while reducing construction time, but without being detrimental to safety and durability requirements.

Šumska prometna infrastruktura u Federaciji Bosne i Hercegovine
2013
Od samih početaka otvaranja šuma pa do danas u Federaciji Bosne i Hercegovine velike su oscilacije u svim segmentima vezanima uz šumsku prometnu infrastrukturu. Sredinom prošloga stoljeća dosta je jaka planska izgradnja i održavanje, a potom slijedi potpuna stagnacija devedesetih godina prošloga stoljeća. U radu je prikazano aktualno stanje u šumskoj prometnoj infrastrukturi u FBiH, s naglaskom na otvorenost šuma, način projektiranja, postojeće šumske ceste i objekte na njima, na intenzitet i kvalitetu izgradnje, intenzitet i kvalitetu rekonstrukcije, na otvaranje traktorskim putovima i žičarama. Nakon provedene analize u ovom su radu izdvojeni najznačajniji čimbenici i dane preporuke za poboljšanje postojećega stanja u šumskoj prometnoj infrastrukturi u FBiH.

Seasonal Variations of Heavy Metals in Atmospheric Precipitation in the Area of Sarajevo Canton
Kemija u Industriji, 2012
Trace metals are natural components of the environment but they have become a matter of great concern because of the continuous increase in the concentrations of these metals in our environment. Atmospheric deposition is considered a major source of toxic metals such as Hg, Cd, Pb and several others in the ecosystem. The increasing use of rainwater as an alternative household water source has led to the increased interest in the monitoring of rainwater quality. <br> <br> The heavy metal (Cu, Cr, Cd, Mn, Ni and Hg) in samples of atmospheric precipitation was determined in order to assess possible contamination of rainwater. The samples were collected continuously during three seasons (winter, spring and summer) in the period from December 2009 to June 2010. The sampling was conducted at two sites of the Sarajevo Canton: Bjelave (urban area) and Ivan Sedlo (rural area). The results showed that heavy metal contents (except copper and cadmium) were higher in samples from Bje...

The forest truck roads are traffic communications which permanently open the forest, and forever take over one of its parts called the width of the cutting area for the road. The decision on the necessity for the truck forest road construction is to be made after a thorough economic analysis of the so called total costs which involve numerous factors. The most important costs are construction and maintenance costs of the road from one side, and timber transportation costs on the other. Besides the economic aspects of the planning and construction of the forest roads network, technical and biological aspects have the same importance. Each of the specified aspects is individually more demanding and more difficult to resolve with the increase of the terrain slope. It is therefore difficult, particularly on steeper slope terrains, to find the best solution for the road route which will be most acceptable in technical terms, economically most cost effective and biologically least harmful for the environment. Generally, when the terrain slope is increasing the road construction costs increase as well because it is necessary to cut the road deeper into the self-growing terrain in order to avoid the construction of expensive supporting walls. Putting the road grade down into the self-growing terrain simultaneously implies an increase of the cutting area necessary for the road construction. The paper analyses how the terrain slope increase affects the width of the cutting area for the road.
New winter triticale species developed at Institute PKB Agroekonomik
Selekcija i semenarstvo, 2015
Izvod U radu su prikazani rezultati ispitivanja prinosa PKB sorti ozimog tritikalea: PKB Vožd i PKB Kardinal u komparaciji sa standardnim sortama: Favorit (Centar za strna žita, Kragujevac) i Odisej (Institut za ratarstvo i povrtarstvo, Novi Sad). Istraživanja su izvedena na Oglednom polju Instituta PKB Agroekonomik, u Padinskoj Skeli, u proizvodnim 2013 i 2014 godini. Utvrđena je visoka značajnost po faktorima: godina i sorta. Najveći prinos ostvarila je sorta PKB Kardinal (9.437,33 kg ha-1), a najmanji sorta Favorit (6.379,67 kg ha-1), u obe ispitivane godine. Novostvorene sorte tritikalea Instituta PKB Agroekonomik imale su značajno više prinose, od standardnih sorti u ogledima.
Uticajni Faktori Na Izbor Područja Pogodnih Za Gradnju Šumskih Kamionskih Puteva

UDK 630*38:625.711.84 Za racionalno gazdovanje šumama i pravovremeno provođenje svih planiranih biotehničkih mjera, neophodno je izgraditi dovoljno gustu i razgranatu mrežu šumskih saobraćajnica. Pri tome se ima u vidu da putevi nemaju značaj samo za proizvodni aspekt šume, već i za sve ostale mnogobrojne aspekte: ekološki, sociološki, zaštitni itd. Najbolje rješenje u otvaranju šuma jeste kada se postigne da se sa što manje uloženih sredstava dobije što bolje otvorena šuma. Rezultat kojem se teži u otvaranju šuma jeste optimalna mreža šumskih saobraćajnica. Optimalizaciju mreže šumskih saobraćajnica je moguće uraditi pomoću matematičke formule minimiziranjem ukupnih troškova. Metode koje optimalizaciju mreže šumskih saobraćajnica rade pomoću računara, analiziraju veći broj faktora i imaju različit pristup u rješavanju otvaranja. U ovom radu je izvršena analiza na osnovu koje su se dobila područja pogodna za gradnju šumskih kamionskih puteva. Uticajni faktori koji su se uzeli za ana...
