Intelektualci in institucije v slovenski zgodovini 17. stoletja
Andrej Koritnik, 2016, doktorska disertacija

Opis: Disertacija želi razkriti in sintetično povezati v kompleksno historiografsko sliko zgodbo 17. stoletja, ki jo razume kot integralni del novega veka, zato je vpogled v 16. stoletje, ko so delovali protestanti (kot posebna forma intelektualcev), in v 18. stoletje, ko so se stare institucije umikale novim in je razsvetljenska filozofija preplavila intelektualne kroge kakor tudi ljudsko kulturo, nujen, da lahko razgrnemo socialno, kulturno in intelektualno zgodovino na Slovenskem v 17. stoletju. Tembolj zato, ker za tedanji čas še ne moremo govoriti o konceptu »nacionalnega«, ki se je povezal z ljudskimi jeziki – pri nas seveda s slovenščino, temveč o počasnem, toda »revolucionarnem« spreminjanju starih družbenih in kulturnih vzorcev, v katerih sta védnost in intelekt legitimno izhodišče za historiografsko, a vseeno interdisciplinarno analizo in sintezo obravnavanega časa. V luči spora med Descartesom in Vicom ter njunima nasprotnima umevanjema zgodovine bo treba premisliti tudi, kako so ideje iz zgodovinopisja vplivale na splošno zgodovino idej, ki se je »dogajala« tudi med Alpami in Jadranom, ter kakšno težo in vpliv imajo »predrazsvetljenski« časi, o katerih pravzaprav ne vemo veliko, na našo sodobnost. Prikazali bomo njeno raznotero, zapleteno podobo kot preplet vseh mogočih silnic – v šolstvu, državni upravi, v fevdalnih razmerjih, v verskih sporih, jezikovni ideologiji, v gospodarstvu in drugod –, skozi katere sledimo liku intelektualca, bodisi kot člana neke institucije védnosti ali pa »osamelca«.

PREPARATION AND CHARACTERIZATION OF HIGHLY PHOTOACTIVE COATINGS ON GLASS SUPPORTS FOR DEGRADATION OF PHARMACEUTICAL SUBSTANCE PARACETAMOL IN WATER
Lidija Sinovčić, 2016, magistrsko delo

Opis: Pharmaceuticals in aquatic environment are considered as emerging environmental contaminants due to their constant presence, evironmental resistance and toxic effect they could have on aquatic organisms. Studies for Slovenia have shown the presence of pharmaceutical substances in waters to be comparable with published results of pharmaceutical water pollution in Europe. As conventional methods do not reach efficient pharmaceutical removal from water sources, more powerful and effective methods like heterogeneous photocatalysis using TiO2/UV have been implemented. Titanium dioxide coatings in silicate binder were prepared by the sol-gel process and deposited on a glass support with dip-coating technique. The films showed good quality and possibility of multiple use. The characterization of the films was performed with scanning electron microscope (SEM), x-ray diffraction (XRD) and hardness test (Elcometer 501 Pencil Hardness Tester). Effectiveness and quality of prepared TiO2 coatings for photodegradation of pharmaceutical compound paracetamol (PCT) were assessed during photocatalytic treatment and compared to photolysis, a process without presence of a catalyst. Photolysis caused substantial changes in paracetamol concentration between 120 and 180 minutes of irradiation where 92% of degradation was achieved, but with no changes in mineralization. Photocatalytic treatment was much faster and effective where 95% of paracetamol degraded within 90 minutes of UV irradiation and after prolonged irradiation time from 120 to 240 minutes also mineralization of paracetamol solution increased from 59% to 83%. Accordingly, toxicity decreased, but it was still not lower than in the starting PCT solution as it was shown by acute toxicity test on Daphnia magna aquatic organisms. The master thesis represents a step forward in studying photocatalytic removal of paracetamol from water, because to my knowledge all the published investigations on this pharmaceutical up to now include photocatalyst mostly in powder and not in immobilized form, which is more advantageous from application point of view.
Ključne besede: Pharmaceuticals, paracetamol, titanium dioxide, photocatalytic degradation, Daphnia magna.

Kontrabantka. Njene poti s koščkom svobode. Življenje in vloga žensk v Vipavskih brdih prve polovice 20. stoletja.
Darja Gorup, 2016, magistrsko delo

Opis: V magistrski nalogi so predstavljene trgovske poti Gaberk iz Vipavskih brd ter vpliv le-teh na spreminjajočo se družbeno vlogo ženske v družini in vasi. Zaradi specifičnih družbeno-gospodarskih razmer, v katerih so živele, je bilo njihovo življenje kmečke gospodinje vse prej kot vpeto med štiri stene. Igrale so več vlog: bile so matere, žene, vaščanke, trgovke oziroma brangerce, kontrabantke in migrantke. Brangerca je ženska, ki je na razne nelegalne ali pollegalne načine nosila jajca, maslo, sezonsko zelenjavo, maline, meso, žganje in druge pridelke v italijanska mesta, jih tam prodala ali menjala in prinesla domov nekaj denarja ali živil in gospodinjskih potrebščin. Ker je državna oblast brangerski način trgovanja omejevala s plačilom taks in dajatev, predvsem pa je bila obdavčena dobičkonosna trgovina z žganjem in tobakom, so ženske pričele s tihotapljenjem. Tako so iz legalnih brangerc postale kontrabantke oziroma tihotapke, trgovke, ki so skušale priti do svojih strank po skrivnih poteh, predvsem pa z domiselno skritim trgovskim blagom. V iskanju boljših pogojev za življenje so se Gaberke tudi izseljevale v bližnja italijanska mesta. V uvodu je predstavljen koncept naloge, teze in metodološka izhodišča. Jedrni del vstavi zgodbe brangerc v različne zgodovinske okoliščine (prva svetovna vojna, vinska kriza po postavitvi rapalske meje ter končno postavitev državne meje med Jugoslavijo in Italijo). Na podlagi podatkov, pridobljenih z metodo ustne zgodovine ter ohranjenega arhivskega ter matičnega gradiva, je predstavljeno vsakdanje življenje žensk ter njihove vloge. V sklepnemu poglavju so zgoščena spoznanja o vrednotenju ženskega dela in vlogah ženske znotraj družine ter vasi. Sklepnemu poglavju sledi seznam literature in virov ter povzetek v angleškem jeziku.
Ključne besede: brangerca, kontrabant, krožne selitve, izseljevanje, Trst, Vipavska brda, rapalska meja

EVALUATION OF MARINE SEDIMENTS FROM THE PORT OF LUKA KOPER FROM THE ENVIRONMENTAL PERSPECTIVE AND IN TERMS OF THEIR USABILITY IN THE BRICK INDUSTRY
Patrik Baksa, 2016, magistrsko delo

Opis: The majority of the world’s goods are transported over water and dredging is essential for the development of harbors and ports. Therefore, the management of dredged material is a worldwide issue. Due to its chemical and petrographic, mineralogical and homogeneity composition, marine sediments are an appropriate raw material to use in the brick industry. Marine sediments can serve as raw material for the production of clay blocks, roofing and ceramic tiles. Different analyses were carried out in order to determine if the dredged material from the Port of Koper is environmentally friendly and suitable to use in the brick industry. These analyses included: a chemical analysis, a mineralogical analysis, a particle size analysis and a chloride content (Cl-) analysis, and tests of firing in a gradient furnace. Furthermore, tests of mechanical properties, as well as tests of frost-resistance of the samples were carried out. On the basis of primary analyses and samples prepared in a lab, it was established that marine sediments from the Port of Koper without any additives are only conditionally suitable as a source material for producing brick products. In collaboration with Gorica brickworks (Goriške opekarne), a pilot production from a mixture of 60% component B from Gorica brickworks and 40% component A (marine sediments) from the Port of Koper was prepared. Different tests showed the mixture could be appropriate for brick production.
Ključne besede: marine sediments, recycling, clay bricks, chemical analysis, mechanical properties, brick production.

THE STUDY OF OPTIMAL TECHNOLOGICAL PROCEDURES OF INTERNAL PLUMBING SYSTEM DISINFECTION FACILITIES IN USE BY THE SENSITIVE HUMAN POPULATIONS
Janez Škarja, 2016, magistrsko delo

Opis: In a developed world, water is used in a variety of installations and devices for the improvement of life standard. It is important for these elements to be suitably managed and maintained, otherwise they can present a risk to people's health. Although potable water from a public plumbing system coming via the water supply into an internal plumbing system normally is compliant with the regulations, the quality of water in an internal plumbing system often changes – water gets contaminated. There are several types of microorganisms that can grow in water. They carry a great potential for the growth and proliferation of bacteria from the genus Legionella that cause Legionnaires' disease and Pontiac Fever. Even the fact that Legionella infection has for several years been mentioned in the accident insurance conditions of insurance companies in relation to receiving the insurance fee as compensation for bed day, shows the extent and foremost the seriousness of the disease (5–15% mortality rate). The research part of the master thesis focused mainly on determining the presence of bacteria from the genus Legionella in the water of internal plumbing systems of healthcare facilities. During the entire research period of 8 years, 2,676 samples of cold and hot water were acquired from 23 healthcare facilities. The main purpose of the research was to determine the efficiency or adequacy of applied approaches, i.e. physical disinfection with heat and chemical disinfection with chlorine, in eliminating or reducing the amount of Legionella present in the water of selected healthcare facilities. Another aim was to evaluate the impact of softening potable water with polyphosphates on the proliferation of certain microorganisms in water, and to determine the by-products of chemical disinfection. Upon sampling, an organoleptic examination of water (appearance, odour), electrometric measurements of water temperature, and colorimetric measurements of free chlorine concentrations in water were performed. The data for the analysis of Legionella presence were acquired by water sampling and the isolation of bacteria found in the water. In order to acquire laboratory results of specific physical and chemical parameters, ion chromatography, gas chromatography, spectrophotometry, titration, and inductively coupled plasma – mass detector were used. Although water samples from only two healthcare facilities showed no presence of Legionella, the number of water samples with the presence of Legionella decreased for at least 25% from the beginning to the end of period set. Also, after certain general sanitary and technical measures a noticeable improvement within healthcare facilities after 2008 could be observed. Regarding the initial part of the set period, a more favourable relationship between positive and negative samples, a lower number of samples with highest concentrations of present Legionella, and a higher number of samples with lower concentrations of present Legionella were determined. The research has shown that the existing system of ensuring health-compliant water is fairly efficient; however, the results could be improved additionally by investing more into the preparation and renovation of systems. Due to a limited number of samples, a direct impact of adding polyphosphates to potable water could not be linked to the occurrence of Legionella. None of the samples showed an increased concentration of by-products of potable water disinfection. In its conclusion, the research has shown that the procedures after overheating and after chlorine disinfection result in a similar success. While filtration proved to be most efficient, from the perspective of Legionella infections the use of medical bathtubs can present a high risk to people's health, therefore such devices should be subject to more frequent maintenance and supervision.

STRUCTURAL PROPERTIES OF MANGANESE-FUNCTIONALIZED SILICA AEROGELS
Tatjana Kobal, 2016, magistrsko delo

Opis: Manganese-functionalized silica with interparticle mesoporosity and isolated Mn sites (Mn/Si = 0.01) is an excellent Fenton catalyst for water cleaning. However, there is a problem that needs to be solved, i.e., Mn leaching from the silica support during the reaction. The solution may lie in using aerogels as the silicate supports for the manganese. The goal of this master thesis is the synthesis and characterization of manganese-functionalized silica aerogels with different Mn/Si molar ratios and a determination of their structural properties. The emphasis is on the preparation of manganese-functionalized silica aerogels with isolated manganese sites. Firstly, manganese-functionalized microporous and mesoporous silicates with a molar ratio Mn/Si = 0.005–0.02 were synthesized according to the literature and characterized as reference materials for manganese-functionalized aerogels. Manganese silicalite-1 (MnS-1) as a microporous zeolite-type silicate and manganese-functionalized silica (MnKIL-2) as a mesoporous silicate were prepared by the sol-gel process with a hydrothermal and solvothermal treatment, respectively. MnS-1 and MnKIL-2 with a molar ratio of Mn/Si ≤ 0.01 contain manganese as isolated sites in the silica framework and with a molar ratio of Mn/Si > 0.01 contain manganese as manganese oxides. Secondly, manganese-functionalized aerogels (MnAEG) with a molar ratio Mn/Si = 0.005–0.02, were prepared according to the acid-base of the sol-gel polymerization of a tetraethylorthosilicate precursor, which is followed in combination with a supercritical drying using CO2. The prepared materials were characterized using the following techniques: X-ray powder diffraction (XRD), energy-dispersive X-ray elemental analysis (EDX), nitrogen physisorption, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The characterization results on manganese-functionalized aerogels (MnAEG) showed Mn oxide nanoparticles incorporated into the aerogel already at a low Mn concentration (Mn/Si = 0.005), which means that Mn aerogels are not promising silica supports for Mn catalysts applied for water cleaning, because they do not contain isolated Mn sites.

ECOLOGICAL STUDIES OF EPIKARST COMMUNITIES IN ALPINE AND PRE-ALPINE CAVES
Federica Papi, 2016, doktorska disertacija

Opis: The karst ecosystem shows heterogeneity and variability of geology, hydrology, morphology and ecology in space and time. Chemical composition of water in karst plays a crucial role not only in dissolution of karst rocks and deposition but also in ecological processes. The heterogeneous nature of karst aquifers leads to difficulties in predicting groundwater flow and contaminant transport direction and travel times. For its position at the top of karst, epikarst represents the interface between surface and underground. Epikarst ecology, biodiversity and fauna have rarely been systematically studied. The typical absence of enterable passages makes necessary an indirect approach. In this research, epikarst biodiversity in relation to environmental conditions was studied in seven Alpine and Pre-Alpine caves, located at different altitudes, in Slovenia and in Italy: Snežna jama na planini Arto (1556 m a.s.l.), Jama pod Babjim zobom (860 m a.s.l.), Zadlaška jama (300 m a.s.l.) and Pološka jama (500 m a.s.l.), in Slovenian Alps and Pre-alps, and Grotta A del Ponte di Veja (600 m a.s.l.), Covolo della Croce (875 m a.s.l.) and Grotta di Roverè Mille (1005 m a.s.l.) in Lessinian Massif. In these caves, percolating water was monthly monitored for fauna in the period of one year. Temperature, discharge, conductivity and pH were measured at the same time, and water samples for the laboratory analyses of total hardness, concentrations of various ions (calcium, chlorine, nitrate, sulphate and phosphate) and dissolved organic carbon were taken. 66 aquatic and terrestrial, mostly hypogean, species were found. Aquatic fauna was dominant in all caves, with the exception of Covolo della Croce. Caves located at higher elevations harbour less diverse communities. No animals were found when discharge was very low and in correspondence of moonmilk formations. The most abundant and diverse group was Copepoda, with thirteen different species and 776 individuals at different maturity stadia, totally representing 61% of the community (between two and three copepod species per cave in Slovenia and between one and six per cave in Italy). The 62% of copepod species were stygobionts. Some copepod species (e.g. Speocyclops infernus) have wide ecological tolerance to environmental variables, other have more restricted tolerances (e.g. Lessinocamptus insoletus). With regard of copepods, there was a good agreement between the number of observed species and the total number of predicted species, confirming that the sampling method was appropriate and sampling complete. Correlations between the copepod community structure and measured parameters, obtained with Pearson correlation coefficient and principal component analysis (PCA) show different patterns. Presence of copepods was positively correlated with conductivity and dissolved organic carbon in Grotta di Roverè Mille, and with carbonate and nitrate in Pološka jama. In other caves not so high correlations were found between copepod species and measured parameters and between pairs of species. Investigations of the Alpine and Pre-alpine epikarst fauna can help to understand better the ecology of the epikarst fauna and its roles within the large range of different shallow subterranean habitats.

SINGLE NUCLEOTIDE POLYMORPHISMS OF THE CHROMOSOME SEGREGATION GENES INVOLVED IN THE DEVELOPMENT OF GASTRIC CANCER
Marija Rogar, 2016, doktorska disertacija

Opis: INTRODUCTION. Gastric cancer represents the fifth most frequently diagnosed cancer in the world. Despite numerous research studies, mechanisms leading to disease are poorly known and unclear. At the molecular level, many changes are involved in the development of gastric cancer, including malfunction of chromosome segregation genes. These abnormalities can lead to chromosomal instability (CIN). Segregation gene function can be affected by the low penetrance errors which include polymorphisms. AIM. The aim of this study is to examine the effect of selected polymorphisms in specific segregation genes on gastric cancer development. HYPOTHESIS. The study focused on exploring genotypes of selected polymorphisms in specific mitotic segregation genes. Those that differ significantly between the subjects and the healthy control population, may be associated with higher risk for developing gastric cancer or with certain clinical and histopathological characteristics, and may have effect on the survival of gastric cancer patients. METHODS. 30 polymorphisms in genes BUB1B, CASC5, ESPL1, PTTG1, SMC1A, TPX2, TTK and ZWINT were included in the study. Subjects were compared with the control group. Polymorphisms were determined using quantitative real-time PCR (qPCR), restriction fragment length polymorphism (RFLP) and DNA sequencing. RESULTS. The association between polymorphisms rs2277559 (BUB1B), rs2241666 (ZWINT), rs11858113 (CASC5) and rs11855334 (CASC5) and increased risk of developing gastric cancer in male population was determined. As concerning rs11855334, statistically significant difference was also observed in the genotype distribution between the whole population of subjects and controls. The association between the genotypes of polymorphisms (in gene BUB1B) rs2277559, rs2290551, rs1801376, rs1047130, rs1565866, rs2277560 and Lauren classification was recognized. Genotypes of polymorphisms rs1801376 (BUB1B), rs11855334 (CASC5), rs2241666 (ZWINT), rs2910101 (PTTG1) and rs1047130 (BUB1B) are linked to different tumour differentiation grades. Survival analysis revealed association between the lymph node involvement and perineural invasion. Statistically higher frequencies of haplotypes G-A-G-T-G-G-A, G-G-A-G-A-A-G and A-G-G-T-A-G-A in gene BUB1B and of haplotypes A-A-A-C and C-C-G-T in gene ESPL1 were observed in gastric cancer patients, whereas haplotypes A-C-A-T and C-A-G-T in gene ESPL1 were significantly more frequent in the control group. Association with gastric cancer was not noted with other polymorphisms. CONCLUSIONS. The association between specific polymorphisms of selected chromosome segregation genes and gastric cancer was recognized. Findings could provide guidelines for further research and polymorphisms linked to gastric cancer could serve as potential diagnostic and prognostic biomarkers.

THE EFFECTS OF MIXED COMMUNAL WASTE RECYCLING MANAGEMENT IN SLOVENIA - CASE STUDY
Peter Bohinec, 2016, magistrsko delo

Opis: With the adjustment of the Slovenian legislation with the European one we have an obligation to increase the reuse and recycling target for municipal solid waste by up to 65% by 2030 and gradual limitation of the landfilling of municipal solid waste to 10% by 2030 (Directive 2008/98 on waste, 2015). This represents a major challenge for municipalities in Slovenia. This study contains a plan for establishing new waste treatment facility in the Municipality of XY. As all new constructions in Slovenia, the presented facility needs to provide all the environmental protective measures predicted by the legislation. Beside the legislation, it is also important to ensure that new waste treatment facilities will have a low or no effect on the environment. Based on the Environmental Protection Act and the Construction Act of Slovenia, measures to ensure long term monitoring of the waste treatment facility as a case study in the Municipality of XY are presented. Before constructing the new facility, the track of “baseline” – a one-year monitoring of the following environmental parameters was crucial: groundwater, air dust deposit, condition of the soil on the area where new facility will operate in the future. The thesis points out the importance of the so-called track “baseline” monitoring of environmental parameters before new waste treatment facility will operate. This will be the basis for the introduction of operating monitoring for the new waste treatment facility in the future. Data for the analysis of presence of pollutants were acquired from groundwater, air dust deposit, soil sampling and containment of chemical pollutants. The following methods of analysis were employed in the acquisition of laboratory results of specific physical and chemical parameters: ion chromatography, gas chromatography, spectrophotometry, titration, inductive coupled plasma – mass detector, measurement with an electrode. It was determined that in the period between 2011 and 2012, the groundwater samples taken from three drilled wells containing pollutants as for example in the P-2 well there were adsorbable organic halogens - AOX, boron and mineral oils found. The results of the dust deposit show increased value of lead and zinc. More concerning are analysis of the soil samples where the quantity of copper at the MM2 measuring point were 530mg/kg, on 20 April 2012 the present critical level was 300 mg/kg. At the same measuring point (MM2) on the same day, the value of zinc was 650 mg/kg and almost reached the critical level of 720 mg/kg. The levels of heavy metals as cadmium, copper, lead and zinc in the soil samples taken at the MM2 and MM3 measuring points were at the warning level. All the detected parameters were evaluated and present a good basis for future operational monitoring of the environment in the area of the new waste treatment facility in the future. This case study has shown that planned steps in the improvement of the waste management in the Municipality of XY are crucial to protect the environment. The analysis and interpretation present an important basis for planning and monitoring a new waste treatment facility which will help to improve our goals and reduce landfilling to 10% and increace recycling by up to 65% by 2030 as predicted by the Directive on waste (Directive 2008/98 on waste, 2015).

ANALYSIS OF ALTERNATIVE CHANCES FOR SLUDGE TREATMENT AT NEW CENTRAL WASTE WATER TREATMENT PLANT
Renata Janja Slovša, 2016, magistrsko delo

Opis: The purpose of this master’s thesis is to present the operation of a large municipal waste water treatment plant in Slovenia with over 300.000 PE and its efficiency, and through a theoretical analysis to present the current practice and alternative options of sewage sludge treatment in Slovenia and around the globe. The main objective of master's thesis is to present the most possible alternative scenarios for the final managing of sewage sludge from WWTPs and at this objective we take into consideration the impact on Carbon Foot Print (CFP). Due to scenarios (thermal utilisation of dried sludge (90% d.m.) in a cement plant, co-incineration of dehydrated sludge (25% d.m.) in a local power plant, thermal utilisation of dried sludge (90% d.m.) in a local power plant, incineration of dehydrated sludge (25% d.m.) in own plant, incineration of dried sludge (90% d.m.) in own plant, and also prohibited scenarios such as sludge utilisation in the soil -fertilization, sludge disposal in the landfill) we calculated CFP and we find out that CFP of various methods of thermal sludge treatment are more or less similar but absolutely smaller than convetional sewage sludge treatment. The CFP is more favourable for dehydrated sludge than for pre-dried sludge, and it is also more favourable for treatment in industrial furnaces (heat power plant, cement plant) than in individual waste incineration facilities.
