ASSESSMENT OF EFFECTIVE DOSES BASED ON VARIOUS RADON MEASURING TECHNIQUES
Nataša Smrekar, 2016, magistrsko delo

Opis: In my master's thesis, I have focused on radon gas in 43 buildings used for different purposes (23 schools, 3 kindergartens, 16 offices and a residential house) in which preliminary measurements had shown higher concentrations of radon gas. I carried out measurements of radon and short-lived radon products whilst simultaneously employing different measurement techniques. In all 43 buildings, I measured the instantaneous concentration of radon by using scintillation cells; in 18 buildings, I additionally measured the average concentration of radon by using solid state nuclear track detectors and in 10 buildings, I measured concentration retrospectively with solid state nuclear track detectors. In four selected buildings (a school, a kindergarten, an office and a residential house), I carried out the measurements by using all of the available equipment. I monitored the daily fluctuations of concentration of radon and short-lived radon products by using continuous monitors in 14 buildings. This is how I obtained the factor of radioactive equilibrium between radon and its short-lived products. Based on the results obtained, I calculated the effective doses. As the basis for calculating the doses, I used the instantaneous and average concentrations of radon and the equilibrium factor taken from literature (0.40) or own measurements. I compared the doses and critically evaluated them. In contrast to the previous research, I researched radon exclusively in areas with increased risk for radon. I studied the influence of the working regime on the concentration of radon in different working environments (i.e. a school, a kindergarten and an office).
Ključne besede: Radon, short-lived radon products, measurement technique, scintillation cell, solid-state nuclear track detector, retrospective detector, equilibrium factor, effective dose, comparison.

Poetični jezik in ponavljanje
Mojca Pretnar, 2016, magistrsko delo

Opis: Delo Poetični jezik in ponavljanje se loteva razmerja med poetičnim jezikom in navadnim jezikom skozi psihoanalitične koncepte. Poetični jezik, kakor ga vidi psihoanaliza, je neločljivi del jezika in temelji na prepletu Lacanovih treh registrov: simbolnega, imaginarnega in realnega - tudi poetični jezik strukturo boromejskega vozla. Poetični jezik, ki ga najdemo v poetičnih besedilih, v primerjavi z navadnim jezikom pomeni spremembo v kodu, ustvarja kršitve in se od navadnega jezika loči po večjem deležu realnega, ki proizvaja različne učinke, zaradi katerih posegamo po poetičnih besedilih. Jezik se konstituira skozi ponavljanje in ponavljanje je moč jezika. Ponavljanje je vse prej kot zaviralna sila, ravno ponavljanje ponuja možnost, da se ustvarja novo. Pretresanje poetičnega jezika skozi dva različna koncepta ponavljanja, ponavljanje, kakor ga vidita Lacanova psihoanaliza in Deleuzova filozofija, potrdi, da se poetični jezik konstituira skozi vse plati ponavljanja. Če poetični jezik proizvaja realne učinke in stvori umetniško poetično besedilo, sestoji iz ponavljanja v vseh treh registrih po Lacanovi tipologiji ali mora biti sklop vseh treh sintez po Deleuzovi tipologiji. To vednost mora v zakup vzeti tudi prevajanje poetičnih besedil, ki je tudi en primer ponavljanja.
Ključne besede: poetični jezik, jejezik, boromejski vozel, ponavljanje v psihoanalizi, Deleuzov koncept ponavljanja, objekt a, literarno prevajanje

FLOODPLAIN FORESTS OF SOČA RIVER BETWEEN KOBARID AND CONFLUENCE WITH RIVER TOLMINKA: CURRENT SITUATION AND DEVELOPMENT
Janez Pagon, 2016, magistrsko delo

Opis: In its upper course the Soča River is one of the best preserved Alpine rivers. Despite that, there have been few studies of its riverine forests, which are an integral part of the river. The research in this thesis encompasses part of the river basin between the towns of Kobarid and the confluence with the Tolminka River. It was found that the riverine forests in the study area are not a homogeneous habitat. Rather, they consist of numerous phytosociological communities with a syn-dynamic connection. The majority of riverine forests in the study area is younger than 50 years old and were established either by the overgrowing of agricultural land or from degraded forests. Accordingly, the forest structure is characterised mainly by uneven-aged stands or younger structural stages, which are frequently returned to their earlier stages due to human impacts. The majority of these forests have low quality prospects. Based on their vegetation and stand characteristics, the riverine forests under study were classified into six stand types. A comparison of the functions and characteristics of particular forest types revealed similarities between the stand types of initial willow, white willow and grey alder. Forests in this cluster are under the influence of soil water and high floodwaters. Their most pronounced function is ecological. In their growing stock, there is a large share of deciduous softwood. Forests in this cluster cover 62% of all riverine forests in the study area. Silvicultural measures are rare in these forests and are less important for the existence of the stands than environmental features like a high level of soil water and minimised human impact on their habitat and the river course. An important characteristic of the second cluster, which consists of pioneer forest on higher-lying river terraces and the riparian corridor stand type is a lack of contact with soil water. In the tree layer of the growing stock in this cluster, species appearing on drier riverine-forest sites prevail (European ash, small-leaved lime, European hornbeam, sessile oak). These forest stands have a greater timber industry potential; therefore, modest measures and limited human impact (especially that which leads to a change in land use like forest grazing and clearing) are recommended. The stands in this cluster cover 30% of the analysed riverine forest area. The third cluster of riverine forests consists of anthropogenic riverine forest stands where the human impact is so significant that they mainly perform a social function. The stand type of this cluster represents 8% of the riverine forests in the study area, and it is suggested that they should be managed as parkland and not as forest areas. Directing visitors to these areas would unburden other, more preserved stand types from the pressures created by human activities (tourism, recreation, construction work). Growth and increment analyses of the most common tree species in the riverine forests in the study area show that mainly olive and white willow, followed by grey alder, have substantial current height (both willow types up to 1.14 m/year), diametric (willow up to 1.4 cm/year) and volumetric increments. However, their rapid growth makes these subjects prone to rapid ageing. The region of northern Primorska was inhabited early in history. Accordingly, there was great pressure imposed on riverine forests already in the past. The analysis of old maps revealed that up to the beginning of the 20th century, the riverine forest area within the scope of analysis was under 50 ha. Within the process of the overgrowing of agricultural land in Slovenia, a process that is currently still underway, the aforementioned riverine forest area increased to 229.16 ha. This thesis shows that the study area is not an unspoiled wilderness. On contrary, just as in the past, it is a crossroads of numerous and frequently conflicting interests. The riverine forest situation on the Soča River in the area b

Time restrictions in forest operations planning
Boštjan Kepic, 2016, magistrsko delo

Opis: This master’s thesis deals with annual harvest operations (AHO) planning with consideration of time restrictions. We developed five models of binary integer linear programming (BILP) that schedule working groups to harvest unit areas (HUAs) according to the lowest cost possible. Total AHO costs include felling and skidding costs, transportation costs, and machine relocation costs. The first model is based on the presumption that harvesting can be planned and executed freely throughout the year. In other four, scheduling was subject to time restrictions in HUAs and differed according to the extent of time restrictions. The second model takes into account time restrictions due to unfavourable natural conditions, the third model due to disturbance-free areas of animal species, the fourth and fifth model concurrently include the impact of time restrictions due to natural conditions and disturbance-free areas. The annual workplace time in Model 2 is reduced by 14.2 %, in Model 3 by 16.9 %, in Model 4 by 29.3 % and in Model 5 by 42.3 %. The model tool used to test all the models was designed in Microsoft Excel. All five models were tested with OpenSolver 2.7.1 software. Increasing the extent of time restrictions in forest operations reduces the utilization of the annual workplace time. In testing the second model, we demonstrated that with proper organisation of an AHO plan the planner can influence the working days fallout. In the other three models, we were able to ensure the implementation of AHO plan by introducing extra working groups. Further, we confirmed that time restrictions affect the scheduling of the working groups and the sequencing of tasks. The increases in total AHO costs were explained as an increase in working groups’ costs due to lower utilization rate, an increase in depreciation costs of machines and costs due to unrealized allowable annual cut and timber sales planned for the current year. We tested each model on two examples.

Birokratski stil v srbskem in slovenskem časopisju v času socializma
Jelena Budimirović, 2016, magistrsko delo

Opis: Glavni namen birokratskega stila ni komunikativen, temveč ritualno-ideološki. Takšen stil služi kot sredstvo jezikovne manipulacije in birokratom zagotavlja monopol pri političnem odločanju. Birokratski stil je v srbščini razcvet doživel v socializmu, v slovenščini pa se je razvijal pod vplivom srbščine. V tej nalogi analiziramo jezik srbskega časopisa Borba, oziroma slovenskih časopisov Ljudska pravica in Delo v času socializma, in sicer skozi dve obdobji – obdobje začetka socialističnega sistema v Jugoslaviji (1944–1947) ter poznejše obdobje, v katerem je imel socializem v Jugoslaviji za seboj že več desetletij (1974–1979). Za jezik prvega obdobja so značilni enostavnost, ideološkost in čustvenost. Za stil drugega obdobja je opazna izjemno močna birokratiziranost novinarskega stila, in smo ga zato analizirali glede na klasifikacijo značilnosti birokratskega stila: nominalnost, splošnost, nedoločenost, eksplicitnost, evfemizmi, presežek besed, kvaziznanstvenost in uporaba besed tujega izvora. Analiza opisuje slovnična in leksična sredstva birokratizacije in razlaga njihove učinke v sociolingvističnem kontekstu.

STREET CHILDREN IN NIŠ (SERBIA): THE CASE OF DROP IN CENTRE FOR THE MOST AT RISK ADOLESCENTS (MARA)
Miodrag Đorđević, 2016, magistrsko delo

Opis: In 2009, a Drop in centre for street children - MARA was established in Niš, Serbia. The purpose of the project was to provide health protection of adolescents, who lived in structural disadvantages, was exposed to the risk of HIV, and who have not been addressed by the institutional social care system. Once on the streets, children have difficulty meeting their basic needs such as obtaining food, clothes or shelter. Therefore, they employ a range of survival strategies. Begging, car washing, collecting secondary resources, borrowing money, and dealing drugs are common ways how to provide subsistence. Perhaps the most dangerous survival strategy pertains to exchanging sex services for food or money. Drug and alcohol use are common practices among street children. The main goal of this thesis was to obtain new knowledge about these young people in order to achieve a better understanding of their behaviours in the framework of social marginalization, their coping strategies and their own contributions to social exclusion. To provide better social, health and educational services for street children in Niš a qualitative approach is necessary to understand their survival strategies and their several needs as the persons at risk in certain social contexts. The main approach was ethnography encompassing participant observation during the fieldwork in Drop in centre in Niš. Following methods were employed: Review of the scientific literature on the issue and analytical reading; Review and analysis of existing documents and archive materials: UN/NGO/Government documents, and the documentation on the projects from Drop in centre; Participant observation in the group of MARA; Semistructured interviews with MARA; An ethnographic diary and ethnographic fieldnotes of fieldwork in the Drop in centre in Niš. This thesis was focused on the following research questions: What is the relationship between social stereotypes about MARA and MARA’s behaviour? Are the stereotypes affecting MARA’s identities, behaviour and appearance or vice versa? How do MARA act within their several environments? How MARA relate to each other? How “street groups” influence MARA’s risky behaviour? What are interactions within these groups? What are the commonly shared values among the members of the groups? My research will explore more in detail common values in the groups of drug users and sex workers. How MARA understand the risk of drug use and commercial sex? What is the social context of risk perception? Do they have any ideas how to prevent the risk? Did they have any concepts about the risk? And how their concept coincides with the mainstream, project concepts? Discussing all above research questions, the main expected result refers to obtaining new knowledge in order to find better solution to their problems compared to existing practices and understandings by several actors. Therefore, this work will fight against poorly informed images and understandings of adolescent Roma and street children, which are as a rule seen and understood within ideological, commonsensical, racial and stereotypical considerations. Roma studies have little academic research on at risk adolescent children, especially in the Western Balkans. The originality of this study is related to the unique material collected in the ethnography through participant observation and fieldwork with appropriate techniques of data collection with adolescent street children in Niš. The study was carried out on the territory of former Socialist Yugoslavia, in Central Serbia, Niš. No similar studies on structural inequality, marginality and Roma has been conducted in this region. Finally,concepts of structural inequality, marginality, street children, which have been coined and developed by several authors in the contexof the Western capitalist system, will be now reflected in the context of transition and postsocialist radical social changes.

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.
