Abstract. The Dinaric Fault System in western Slovenia, consisting of NW–SE-trending, right-lateral strike-slip faults, accommodates the northward motion Adria with respect to Eurasia. These active faults show a clear imprint morphology, and some them hosted moderate instrumental earthquakes. However, it is largely unknown if also had strong earthquakes late Quaternary. This hampers our underst...
Changes in the climate may have unpredictable effects on belowground carbon processes and thus, balance of boreal forests. To understand interactions these soil to quantify potential changes cycle, partitioning forest floor respiration is crucial. For this purpose, we used nine different treatments separate sources dioxide (CO2) emissions a mature Scots pine (Pinus sylvestris L.) stand southern...
ON THE CORROSION MECHANISMS OF Al-Cu-Li ALLOYS: AN INVESTIGATION USING GLOBAL AND LOCAL ELECTROCHEMICAL TECHNIQUES. In this study, the corrosion mechanism of an alloy manufactured by two different treatment routes (T3 and T851) was evaluated immersion electrochemical tests in solutions containing chloride ions (Cl-). For both alloys, formation cavities on surface associated with micrometer-size...
ROV trencher is a kind of which trenches the sea floor using specifically designed tool and buries subsea cables pipelines. According to soil conditions, this trenching method can have two different types, one mechanical cutting other water jetting. In paper, we present jet design for 2500 m depth-rated trencher. A series CFD simulations laboratory tests with nozzle, ground test 1:6 scale jetti...
Northern forest soils are a major carbon (C) reservoir of global importance. To estimate how the C balance in these will change, roles tree roots and soil microbes should first be decoupled. This study determined activity heterotrophs together with root-associated rhizosphere varies coniferous boreal, hemiboreal, temperate climates along latitudinal gradient using trenching approach. We created...
Poor success of seagrass Posidonia oceanica transplanting in a meadow disturbed by power line burial
Local disturbances drive the decrease of area covered by Posidonia oceanica in Mediterranean. Mechanical impacts during development coastal infrastructures alter sea floor and recolonization benthic community will depend on recovery pre-disturbance environmental conditions intrinsic characteristics local that was disturbed. We transplanted 468 rhizome fragments 450 seedlings P. a meadow disturb...
