Part of geodesist and geodesist company in process of an acquisition\ud of the bulding permit, building and keeping records of the buildings
The way from the idea to the realization in building constructions demands a complex\ud
procedure of land reclamation, projective solutions and requesting permits. In my final thesis I\ud
have described a practical example of the contents of the building permit and the procedure\ud
for obtaining it. I will present the individual phases in building six constructions in Ljubljana\ud
in the cadastre of Slape. In my thesis I will also present the procedure of parcellation, of\ud
setting out the constructions, of measurements of the existent situation and the procedure of\ud
registration in the oficial records
Distribution of rare earth elements in sediments of the marine lake Mir (Dugi otok, Croatia)
The Lake Mir represents a small, isolated and shallow marine lake situated in the south- eastern part of the Dugi Otok Island, in a karstic landscape of the eastern Adriatic coast. The surrounding karstic background, with occasional occurrences of red soil, characterizes the sediments in the lake as coarse grained and carbonate rich. Previous studies suggested the influence of the lake bathymetry and the overall biological production on the element composition of the lake sediments. To confirm previous assumptions and obtain a better understanding of the factors influencing sediment composition of this marine lake, the distribution of rare earth elements in sediments of the Mir Lake and the nearby Telašćica Bay as well as surrounding soils was investigated. In the lake sediments REY ranged from 10.6 mg kg-1 to 25.3 mg kg-1 ; in the Telašćica Bay sediments REY were higher compared to the lake and ranged from 56.4 mg kg-1 to 85.2 mg kg-1, while the highest REY, from 83.3 mg kg- 1 to 227 mg kg-1 were observed in soils surrounding the lake. Despite the difference in the levels of the rare earth elements, the REE normalized patterns and associated fractionation parameters (LREE/ HREE, (La/Yb)N and (Nd/Yb)N) showed similarities between the lake sediments and the surrounding soils, confirming a significant influence of local lithology on the lake composition. Results of the statistical analysis, on the other hand, suggest the contribution of both the carbonate and non- carbonate minerals, i.e. alumosilicates and Al- Fe-hydroxides, on the total REY content in the lake sediments
Dissolved trace metals and organic matter distribution in the northern Adriatic, an increasingly oligotrophic shallow sea
We report a monthly distribution of Zn, Cd, Pb, Cu, Ni and Co, biologically relevant trace metals (TMs), within one year, in the productive surface layer at two stations with different trophic characters in the northern Adriatic (NA). The TM data was accompanied by a multivariable dataset, including dissolved organic carbon (DOC), surface- active organic substances (SAS), nitrogen containing polymeric organic material (N-POM), nutrients, pH, dissolved O2 , chlorophyll a (Chl a), seawater temperature, and the Po River discharge rate. At the eu- to mesotrophic station 108, the concentrations of dissolved TMs were 5– 116 nM for Zn, 0.04–0.18 nM for Cd, 0.05–0.63 nM for Pb, 3–17 nM for Cu, 4–11 nM for Ni, and 0.2– 1.2 nM for Co, while at the oligotrophic station 107, they were 6–224 nM for Zn, 0.03–0.16 nM for Cd, 0.05–1.25 nM for Pb, 3–17 nM for Cu, 4–19 nM for Ni, and 0.1–0.7 nM for Co. The characterization of organic matter (OM) in conjunction with the analysis of correlations with TMs indicated that the OM–TMs interactions differed between the two stations ; namely, the freshly produced OM detected at station 108 was probably involved in the complexation of Cu, Co, Cd, and Ni, whereas at station 107, such complexation processes were not present. Accumulation of DOC was observed during the summer months at both stations. Our results present a significant contribution to biogeochemical studies in the NA by focusing on the complexity of TM–OM interactions, which is a prerequisite for interpretation of their responses to local and global changes
