Klasični postupci obrade (pročišćavanja) otpadnih voda uključuju različite fizikalne, kemijske i biološke postupke čija primjena može biti ograničena zbog velikih investicijskih troškova ili u nekim slučajevima slabe efikasnosti pročišćavanja. Zbog toga se kontinuirano istražuju novi načini obrade otpadnih voda koji bi poslužili kao nadopuna ili alternativa klasičnim postupcima. U radu je dan osvrt na razvoj nanotehnologije u pročišćavanju otpadnih voda, utjecaj nanomaterijala na zdravlje ljudi i okoliš te prikaz budućih trendova razvoja nanotehnologije.

The hydraulic-hydrology analysis and discharge hydrograph results for the Golubinka karst spring are presented for the period from 7 September 2012 to 1 October 2013. The objective was to gain insight into processes occurring in the Golubinka spring drainage area, in terms of quantities of discharge, groundwater levels, and seepage within the karst aquifer, as related to the precipitation measured during the analysed period. An appropriate coefficient of turbulent seepage through karst channels in the analysed aquifer was determined based on two approaches. This coefficient can subsequently be used in numerical modelling.

U radu se prikazuje analiza utjecaja raznih vrsta temeljnog tla na dinamično ponašanje armiranobetonskih minareta. Za potrebe istraživanja u laboratoriju je izrađen ab model u mjerilu 1:20. Kako bi se ustanovile razlike u dinamičkom ponašanju modela minareta ovisno o vrsti temeljnog tla, kao temeljno tlo korišten je šljunak, pijesak i mješavina gline i šljunka. Eksperimentalna mjerenja su provedena pomoću operacionalne modalne analize (OMA), pri čemu su u obzir uzete okolne vibracije uslijed djelovanja vjetra i prometa. Rezultati ispitivanja pokazuju da vrsta temeljnog tla bitno utječe na dinamičko ponašanje ab minareta.

The research presented in the paper is conducted to evaluate properties of fly ashbased geopolymer coated aggregates and their effect on characteristics of bituminous mixtures. The investigation included aggregate testing, scanning electron microscope (SEM) analysis of fly ash and fly ash-based geopolymer, Marshall mix design, indirect tension test, dynamic shear rheometer (DSR) test for rheology, and repeated load test on bituminous mixtures with fly ash-based geopolymer coated aggregates.

The response of geofibre-reinforced sand to dynamic loading is investigated in this paper in terms of excess pore pressure generation and post-cyclic load reconsolidation. Strain-controlled, undrained triaxial tests were performed on saturated sand specimens prepared with varying geofibre content. Tape type and fibrillated type polypropylene geofibre were used with Ottawa (C-109) sand at 0.2%, 0.5%, and 1% dosages by dry weight of soil. The tape type geofibre was found to be more effective than the fibrillated type in reducing the excess pore pressure. Both the type and content of geofibre were found to influence the post-loading settlement.
