Wastewater treatment : master's thesis

Naglim porastom ljudske populacije na Zemlji u zadnjih nekoliko desetljeća te razvojem urbanizacije i industrijalizacije, dolazi do sve većeg onečišćenja vodnih sustava. Jedan od gorućih problema su otpadne vode. Velike količine otpadne vode ispušta se u mora, rijeke ili jezera bez prethodne obrade te ugrožavaju okoliš i ljudsko zdravlje. U diplomskom radu su opisani izvori otpadne vode, procesi obrade otpadnih voda, te zakonska regulativa Republike Hrvatske vezano uz ispuštanje otpadnih voda u okoliš.The rapid growth of the human population on Earth in recent decades, along with urban development and industrialization has resulted in ever increasing pollution of water systems. One of the main problems related to water systems pollution is wastewater discharge. Large quantities of wastewater are discharged into the sea, rivers or lakes without prior treatment, endangering the environment and human health. In this master’s thesis the sources of wastewater, wastewater treatment procedures and national legal regulations on discharge of waste water are described

DIGITAL SURROGATES OF OSIJEK INNER CITY\u27S PRINTING INDUSTRY AS A PRIMARY SOURCE OF HERITAGE

Tiskarstvo osječkoga Nutarnjeg grada iz 18. i 19. stoljeća relevantan je izvor oblikovanja kulturološke slike prostora grada toga vremena. Nakladničkom djelatnošću I. M. Divalda i njegovih nasljednika Osijek prerasta u središte svjetovne i pučke književnosti, a izdanja Divaldiane oblikovala su trojezičnu slavonsku književnost i osobit put hrvatske kulturne i književne tradicije. Suvremenom informacijskom tehnologijom i procesom digitalizacije važno je osigurati vidljivost ovoga gradiva poštujući načelo demokratičnosti. Na taj način nastaju digitalni surogati. Baština više neće biti samo određena lokacijom, već će postati odredištem. Digitalna zbirka dobiva svoju vrijednost tek s ispravno pridruženim metapodatcima koji imaju ključnu ulogu u razumijevanju identiteta zbirke kao i njezine uporabljivosti u globalnome društvu. Svaki digitalni proizvod treba usmjeriti na korisnika, a vrednovanje treba poslužiti kao instrument promjene. Fragmentirana baština digitalnom konvergencijom otvara put njezinoj cjelovitosti i razvoju fenomena grada.The 18th and 19th century printing industry of Osijek Inner City is a relevant source that gives insight into how the cultural images of the city were created in that period. The publishing work of I.M. Divald and his successors allowed Osijek to become a center of world and folk literature, while their publications, known as Divaldiana, shaped the trilingual Slavonian literature, as well as the direction of Croatian cultural and literary tradition. While adhering to the democracy principle, it is necessary to ensure the transparence of this material by means of modern information technology and the process of digitalization. That is how surrogates are created. Heritage will no longer be solely determined by its location; however, it will become a destination. By joining metadata properly, the digital collection becomes valuable as these data play a key role in explaining the collection identity, along with its usefulness in a global society. Every digital product should be user-oriented, and the assessment should serve as an instrument of change. By subjecting fragmented heritage to the process of digital convergence we are allowing for its integrity, and the development of the city phenomenon

FEASIBILITY OF INVESTMENT IN RENEWABLE ENERGY SYSTEMS FOR SHIPYARDS

Shipbuilding industry is generally considered as one of the key global industries. It consumes a significant amount of energy and leaves a strong footprint on the environment. It is therefore required to try to increase renewable energy sources in the shipbuilding industry in accordance with the adopted international legislation. This will improve energy efficiency of shipyards and reduce their impact on the environment. The present preliminary study contributes to those goals as application of sustainable renewable energy systems in ship production industry is considered. The analysis is performed for solar panels, tidal and wind turbines with respect to their technology readiness and investment costs, as well as for the total energy consumption. While in the present work the research hypothesis is studied on example of a typical Croatian shipyard, the general findings are expected to be widely applicable to all shipyards. The solar panels are considered as the most suitable renewable technology, while the investment return period for introducing solar panels to satisfy the entire electrical energy demand in this particular case is approximately seven years. The impact of introducing this green shipbuilding approach is considered beneficial in comparison with current conventional electrical energy production based on conventional energy sources

Valuation of Agricultural Land Fragmentation

Fragmentacija zemljišta kojim raspolažu poljoprivredna gospodarstva u Republici Hrvatskoj i njihova mala prosječna veličina jedan je od glavnih ograničavajućih faktora održivosti obiteljskih poljoprivrednih gospodarstava. S obzirom na prepoznato stanje u RH, novim politikama ruralnog razvoja donose se mjere zemljišne politike kojima je svrha smanjivanje fragmentacije zemljišta. Ovaj rad obuhvaća pregled i ocjenu literature o metodama i tehnikama određivanja stupnja fragmentacije zemljišta, te pregled pokazatelja za određivanje fragmentacije zemljišta. Prikazani su relevantni statistički podaci o prosječnim veličinama poljoprivrednih gospodarstava u RH i EU. Određen je stupanj fragmentacije poljoprivrednih gospodarstava testne katastarske općine pomoću poznatih indeksa fragmentacije primjenom automatiziranih postupaka analiza prostornih podataka te su prikazani dobiveni podaci.Land fragmentation of the agricultural holdings in the Republic of Croatia and their small average size are one of the limiting factors for the sustainability of family farms and the development of Croatian agriculture. Considering the present situation, implementation of rural development policy in the entire rural area of Croatia is a recognized need, and necessary land policy measures were made. This work includes a review and evaluation of the literature on the methods and techniques for determining the degree of land fragmentation, and an overview of indexes used for determination of the land fragmentation. Relevant statistics considering average householding size for the EU and for Croatia are presented. The degree of land fragmentation of the agricultural holdings is determined for the test area of one cadastral municipality, applying the spatial data analysis and the resulting data is presented

Improvement of National Spatial Data Infrastructure as a Public Project of Permanent Character

Izgradnja infrastrukture prostornih podataka podrazumijeva poboljšanje postojeće infrastrukture koje se može definirati kao niz aktivnosti kojima je cilj olakšavanje pristupa postojećim prostornim podacima i njihova šira diseminacija te bolje, jednostavnije i učinkovitije korištenje. S obzirom na značaj i koristi koje nacionalna infrastruktura prostornih podataka ima za cijelo društvo, to poboljšanje treba razmatrati kao javni projekt trajnoga karaktera. U ovom je radu dan pregled planiranja i provedbe takvog projekta kao jedan od mogućih načina poboljšanja postojeće nacionalne infrastrukture prostornih podataka u Hrvatskoj.Establishing a spatial data infrastructure means improving the existing one and can be defined as a number of activities aiming at easier access to and wider dissemination of the existing spatial data, and easier and more efficient use of them. Considering importance and benefits of the spatial data infrastructure for the whole society, the improvement should be seen as a public project of permanent character. This paper gives a theoretical overview of planning and implementation of such project, as a possible model of improving the existing national spatial data infrastructure in Croatia
