Bioavailability and geochemical characteristics of recent marine sediment of Makirina Bay (Northern Dalmatia, Republic of Croatia)
Full text linkThe primary purpose of the dissertation is to estimate the pollution status of Makirina Bay, situated in Northern Dalmatia. Within the research framework, a detailed analysis of recent marine sediments (peloid), seawater and marine biota (flora and fauna) of Makirina Bay has been carried out. Grain size distribution, mineral, elemental and microbiological composition of peloid have been determined, as well as its organic carbon content, PTE (Potentially Toxic Elements) and REE (Rare Earth Elements) mobility. PTE and REE concentrations were also identified in seawater and biota of Makirina Bay. The concentrations of most PTE in the peloid do not exceed the PEL (Probable Effect Level) value and permissible levels for soils in Slovenia and Croatia. Moreover, the contents are comparable to their respective concentrations in peloids already used in various wellness centers around the world. The results of the sequential extraction method showed that PTE in recent marine sediment are bound to different factions. The major proportion of most PTE is bound to the residual. The PTE in residual are retained within the crystal lattices of minerals, and thus the PTE bound to this component are regarded as stable and are not susceptible to remobilization in normal environmental conditions. Among non-residual fractions, the oxidative fraction is the most important, wherein the PTE are associated with organic matter and/or sulfides. The calculated RAC (Risk Assessment Code) value indicated that the PTE (except Cd and Mo) pose a low to medium risk to the aquatic environment. The sequential extraction method results coincide partly with the findings gained with the BSAF (Biota-Sediment Accumulation Factor) calculation. Distribution of the PTE in seawater is similar to the PTE distribution in recent marine sediment. According to the comparison, only the Cr concentrations stand out. The concentrations of Cr are among the highest in recent marine sediment, while in seawater below detection limit. For some PTE concentrations in recent marine sediments and seawater the impact of anthropogenic activity cannot be completely excluded. Therefore, an environmental policy is advisable for the Makirina Bay and its surroundings
The development of rural settlements in compliance with the tradition and the requirements of submicroregion
Full text linkThe subject of this Master of Science thesis is the development of the rural settlements. The theoretical part handles the questions of condensation of the settlement, its internal development, categorization, submicroregion, sustainable development, traditionality and development guidelines, besides the display and the comparison of the development of rural settlements in some European countries. The methodological part shows the five-phase approach, which includes the definition, determination and evaluation of the indicators, the analysis of the development stages and the derivation of the development guidelines with SWOT analysis for strategical planning and the project approach for the implementation planning. The approach is used in the case which handles the strategy of development of rural settlements in Postojna municipality, and in the case that handles the implementation of the project intervention in the closed section of the settlement Dolnja Košana
Analysis of the apartment rental market in Slovenian city municipalities
Full text linkThe thesis presents the housing legislation in Slovenia since 1991. Positive and negative sides of home ownership and home renting are described. The rent for non-profit housing is formed according to the law following a valid methodology, while the rent for commercial housing is formed freely. The thesis contains an analysis of apartment rental market in 2014 based on signed lease agreements. A detailed analysis has been made on rent prices, the volume of renting and characteristics of the rental apartments within Slovenian municipalities. Analysis of rented apartments were performed also by city zones of each city municipality, which were created especially for this assignment and derive from zones of mass real estate appraisal models. The rent analysis showed that most of apartments were rented in city municipality of Ljubljana where the rent prices were also the highest. Presence of a university in a city municipality also influences the number of rented apartments. There have been many more lease contracts signed there, as opposed to municipalities with no university. In individual city municipalities the rents are the highest in city centre areas. It has been found that in some city municipalities the zones of mass real estate appraisal models are appropriate for analysing apartment prices and rents, while in other locations, such as city municipality of Maribor, those models are not usable. A t-test was carries out in order to determine whether the average apartment rents per unit in individual city municipalities and inside their zones characteristically differ from each other or not. The results showed a significant statistical difference among average apartment rents per unit in majority of city municipalities observed, a conclusion we cannot make for average rents between different zones of a certain city municipality
Small hydropower plants in a rift between impacts on the environment and development opportunity of renewable energy sources
Full text linkRenewable energy sources ensure cleaner and more environmentally friendly energy. The potential to use the renewable energy in Slovenia is high and underexploited. Small hydropower plants are an important part of renewable energy and their developmental potential is still high. \ud
HYPSE programme has been developed to carry out multi-criteria decision-making methods in the siting of hydropower plants in an area. The advantage of computer support in the decision-making process is the increased number of processed information and the reduced number of biased decisions. \ud
The first part of the thesis is a theoretical introduction, which generally summarizes electricity, energy policy, renewable energy sources as well as emerging problems and solutions. It gives a general description of small hydropower plants and the impact of damming and water abstraction on aquatic ecosystems. The second part uses the HYPSE programme and the available data to make a comparison of six selected small hydropower plants. With an equivalently placed economic and environmental criteria and according to the annual amount of energy produced, a small hydropower plant is selected which has the minimum impact on the environment
Hydraulic analysis of water distribution system of Naklo
Full text linkEfficient water distribution is one of the basics for a normal living in a modern society. Water distribution systems (WDS) enable efficient water supply, if they are properly constructed, maintained and managed. WDS are made of many components, which are connected together and have to work coordinated. Because of complexity of these systems it is difficult to determine pressures and flows in this networks. Nowdays network operators are using hydraulic models to provide these hydraulic quantites. This graduation thesis is showing how to build a hydraulic model, calibrating it and using it in the hydraulic analysis of WDS of Naklo. The public utility Kranj, which is operating with WDS Naklo, has built a new transport pipeline. The plan is to connect this pipeline with WDS Tržič, which would also become a new and replace the current water source for WDS Naklo. I elaborated hydraulic analyses for two possible pressure boundary conditions on inlet in WDS Naklo from WDS Tržič. The third hydraulic analysis was on the connection between WDS Naklo and WDS Kranj. The WDS Kranj would be supplied by additional water quantities from WDS Tržič. Building these hydraulic models and elaborating the hydraulic analyses was done using the GIS software Qgis, its plugin qgis-epanet and hydraulic simulation software EPANET 2.0
Cost aspects of connection to public sewerage system
Full text linkThis graduation thesis deals with issue of costs for individual building owners in relation with connection to the public sewerage system, i.e. construction of individual sewerage connection. On the basis of selected project examples of public sewerage systems in smaller villages, first part of thesis is dedicated to different kinds of sewerage connections, where the most important aspect is length of the sewerage connection.\ud
Hereinafter individual (house) connections are evaluated according to selected length groups on the basis of inventory works and pre-measurements. First part of the thesis concludes with comparison of comprehensive cost value of building of public sewerage network with regards of costs of such network for municipality on one hand and costs for owners of individual buildings on the other. \ud
Second part of the thesis deals with the issue of increasing costs of individual (house) sewerage connections for individual building owners, depending on terrain endowments (type of soil, the size of the depth of excavation).\ud
The last part of thesis addresses reducing of costs for citizens in cases where due to terrain endowments costs for building of individual (home) sewerage connection is too high. \ud
In conclusion I try to display possible solutions and good practices of some municipalities, which try to ensure most even distribution of costs between different building owners, who are interested in connecting their buildings to public sewerage system in one municipality
Economic performance of single - family house construction on the outskirts of Novo mesto
Full text linkThe thesis analyses the economic performance of constructing single-family houses on the outskirts of the City municipality of Novo Mesto. It compares the construction costs with selling prices of single-family houses. The analysis involved three single-family houses with building permits, for which we devised the design documentation. Moreover, it contains a detailed list of all the construction costs of such buildings and presents the analysis of sold vacant construction land on the outskirts of the municipality. The goal is to assess the market value of the construction land associated to the three single-family houses. In addition, the thesis contains the analysis of single-family houses selling prices, which served as the basis for assessing the market value of such buildings.\ud
The findings suggest that the investment in this type of turnkey single-family houses around the City municipality of Novo Mesto is not economically viable

Proposal for categories of land use with a comparison of international classifications
Full text linkThe master's thesis deals with the classification of land use. It provides a theoretical background for classification systems and presents ten examples of actual land use classifications in selected countries and pieces of research. The examples involve countries with an established approach to registering land use, countries that have modernised it in the past ten years or are doing so at the moment, transnational registering projects, directives and other projects aiming to manage land use registering. The proposed classification of actual land use was developed on the basis of examples and recommendations for classification systems in line with the European INSPIRE Directive and implementing or ongoing projects, such as EAGLE (2013) and LBCS (2000). Each category of land use was described and linked to the Classification of facilities. The discussion searched for a connection between the proposed classification of land use with the categories of land use allocation under the Spatial Planning Act (2007) and the Standard Classification of Activities. Moreover, it examined whether the proposed classification of categories can serve as the basis for identifying builtup and greenfield land. The research results suggest that a register of land use is necessary, but insufficient for further analyses
Energy analysis and renovation proposal for the community health centre Fužine building
Full text linkEuropean environmental policy demands a transition toward nearly zero-energy buildings. Its goal is to reduce energy consumption and increase the use of renewable energy sources. In the diploma thesis, different building energy parameters needed to evaluate energy efficiency are presented and calculated for the Community health Centre Fužine building. Firstly an analysis was carried out to determine whether the building complies with the current regulatory requirements for energy efficiency. This was followed by the calculation of the annual heating energy demand using the TOST program. Based on the results, different measurements were presented and evaluated in order to lower the annual heating energy demand. The three most efficient, technological and economical solutions led us to determine the minimal energy consumption that comply with the current standards. Annual heating energy demand was 77,79 kWh/m2 before the renovation and 7,92 kWh/m2 after it, a result that would rank the building in the highest energy efficiency class. With the renovation, energy efficiency would be improved 100 . In the final part of the diploma thesis a renewable energy source is presented, together with a possible way of using it to make the Community health Centre Fužine building nearly zero-energy building
