    Klizište u zoni mosta Slobode u Novom Sadu je jedno od najviše istraživanih klizišta u Srbiji iz razloga što predstavlja ozbiljnu prijetnju po stabilnost pomenutog mosta preko Dunava. U vrijeme završetka izgradnje 1981. godine, ovaj most s kosim kablovima, bio je na svijetu s najvećim središnjim rasponom od 351 m. U tijelu klizišta, most je temeljen na armiranobetonskim pilotima duljine 27 m. Utvrđena dubina pomicanja za prvi klizni blok iznosi 26 m, a za drugi 35 m. Projektirani drenažni sus...

    A mathematical modal is presented for the hydrodynamic process of modifying the pressure pulse of rocks with different reflecting properties. It can be used to control both stripping of the bed, and to prevent emergency situations of the oil seal formation type. This hydrodynamic process is described by a nonlinear system of differential equations. The boundary conditions are the condition of reflection of the conducting flux by the rocks with different coefficients of reflection (dissipation of the stream energy). Results are presented from calculation on the computer YeS-1020 for drilling strings 1,000 m long and 3,000 m for rocks with coefficients of reflection K=0.001-0.1.

    Četrdeset i četiri kristala brazilijanita s nekoliko lokaliteta iz Brazila, Ruande i Kanade je mjereno na dvokružnom refleksnom goniometru u svrhu određivanja morfologije. Zabilježeno je 20 formi, od kojih šest do sada nije opisano. Sve plohe u zoni [001] su prutane paralelno kristalografskoj osi c. Sve prutane forme u [001] zoni daju višestruke signale. Forma {110} daje višestruke signale od kojih su dva uvijek oštra. Postoji iznimka gdje na jednom kristalu samo jedna ploha, (110), daje samo...

  4. Onečišćenje zraka u području odlagališta otpada Jakuševec i u okolnim naseljima

    Prva ciljana mjerenja kakvoće zraka u zoni utjecaja odlagališta otpada Jakuševec započela su u naseljima Jakuševec i Mičevec u ljetu 1995. godine prije početka sanacijskih radova i nastavljena su do kraja 2004. godine. Rezultati mjerenja tijekom godina pokazali su znatne sezonske varijacije mjerenih onečišćenja te su koncentracije hlapljivih spojeva, osobito vodikova sulfida, merkaptana, amonijaka, žive i plinovitih fluorida bile znatno više ljeti negoli zimi. Tijekom sanacijskih radova povre...

    This research reports the preliminary results of a study based on the SOC (Soil Organic Carbon) fractionation in a pine forest soil (Pinus nigra). Hyperskeletic Albic Podzol soil (P113005, World Reference Base, 2014), described by the following sequence O-Ah-E-Bh-Bs-Cg, was investigated at Zoniën, Belgium. Total (TOC) and extractable (TEC) soil contents were determined by Italian official method of soil analysis. Different soil C fractions were also determined: Humic Acid Carbon (HAC) and Fulvic Acid Carbon (FAC). Not Humic Carbon (NHC) and Humin Carbon (Huc) fractions were obtained by difference. Along the mineral soil profile, therefore, were also tested some enzymatic activities, such as cellulase, xylanase, laccase and peroxidase, involved in the degradation of the main organic substance components, and dehydrogenase activity, like soil microbial biomass index. The results shows a differential TEC fractions distribution in the soil profile along three fronts of progress: (i) An E leaching horizon of TEC; Bh horizon (humic) of humic acids preferential accumulation, morphologically and analytically recognizable, in which humic are more insoluble that fulvic acids, and predominate over the latter; (ii) horizon Bs (spodic) in which fulvic acids are more soluble that humic acid, and predominate in their turn. All enzyme activities appear to be highest in the most superficial part of the mineral profile and decrease towards the deeper layers with different patterns. It is known that the enzymes production in a soil profile reflects the organic substrates availability, which in turn influences the density and the composition of the microbial population. The deeper soil horizons contain microbial communities adapted and specialized to their environment and, therefore, different from those present on the surface The results suggest that the fractionation technique of TEC is appropriate to interpret the podsolisation phenomenon that is the preferential distribution of
