<p>Teza se bavi religijskom istorijom rimske provincije Druge Panonije (Pannonia Secunda), formirane administrativnim reformama cara Dioklecijana (284-305) na prostoru jugoistočnog dela nekada&scaron;nje provincije Donje Panonije (Pannonia Inferior). Hronolo&scaron;ki tema je ograničena na 4. vek s obzirom da u to vreme dolazi do krupnih i dalekosežnih promena u religijskoj politici Rimskog carstva. Ovo je period tranzicije između stare helensko-rimske religioznosti i hri&scaron;ćanstva u razvoju. U toku jednog veka učinjen je prelaz od progonjenog hri&scaron;ćanstva kao religio illicita iz vremena prve tetrarhije (293-305) do potpuno afirmisanog hri&scaron;ćanstva kao jedine legitimne državne religije (381).<br />Druga Panonija je tokom 4. veka postala caput Illyrici ne samo kao administrativni i politički centar novoformirane teritorijalne prefekture Ilirik, već i u crkvenom pogledu sedi&scaron;te Sirmijske mitropolije. Podizanje vojno-političkog značaja ove provincije, donelo je rimskoj koloniji Sirmiju rang carskog grada u kome su zbog nestabilnosti donjedunavskog limesa često boravili carevi i dvor. Shodno tome, Sirmij je u progonima hri&scaron;ćana tetrarhijskog perioda zabeležio najveći broj mučenika u odnosu na ostatak Ilirika. Zapisi o stradanju sirmijskog episkopa Irineja, njegovog đakona Dimitrija, cibalskog lektora Poliona, sirmijske građanke Anastazije i ba&scaron;tovana Sinerota i drugi udarilo je temelj martirolo&scaron;koj književnosti Ilirika i dalo osnov za poznavanje organizacije i života prvih hri&scaron;ćanskih zajednica u Drugoj Panoniji. Prvi deo teze proučava ovu bogatu literarnu tradiciju, podrvrgava je istorijskoj kritici i nadopunjuje podacima arheolo&scaron;kih izvora vezanih za kultove mučenika Druge Panonije.<br />Posle legalizacije hri&scaron;ćanstva i zahvaljujući stalnom prisustvu carske administracije i dvora, Sirmij je za celo područje Ilirika postao glavno crkveno sedi&scaron;te, u kome su se u periodu od 349. do 378. održali crkveni sabori i donete formule vere od velikog značaja za op&scaron;ti tok istorije hri&scaron;ćanstva.&nbsp; Tako je značajan segment teze posveće ulozi Druge Panonije u hristolo&scaron;kim raspravama od Nikejskog do Akvilejskog sabora (325-381), analizi sirmijskih sabora i formula vere, ulozi mursanskog episkopa Valensa u crkvenoj politici homojskih pristalica, učenju sirmijskog episkopa Fotina i teolo&scaron;koj poziciji Germinija Sirmijskog.<br />Hronolo&scaron;ki poslednja tema disertacije jeste period konsolidacije nikejskog pokreta na Akvilejskom saboru (381), na kom sirmijski episkop Anemije bio aktivni učesnik i &scaron;tićenik moćnog Ambrozija Milanskog. Verska konsolidacija Druge Panonije i njeno pristajanje uz trinitarnu teologiju, odigrala se u periodu političke i kulturne dezintegracijom prouzrokovane ubrzanim padom donjedunavskog limesa i varvarizacije panonskih provincija.&nbsp;&nbsp;<br />S obziroma na značajne rezultate arheologije u proteklih pet decenija, autor je na osnovu materijalne ekspresije religije stanovnika Druge Panonije prikazao odlike načina sahranjivanja i formiranje verske topografije najznačajnijih lokaliteta. Autor je sakupio i obradio neobjavljenu rukopisnu građu relevantnu za martirologiju Druge Panonije, kao i neke neobjavljene ranohri&scaron;ćanske natpise sa ovog područja, koji pomažu u rekonstrukciji religijskog života stanovnika Druge Panonije u 4. veku.<br />Cilj teze bio je sveobuhvatno interdisciplinarno istraživanje ključnog perioda religijske istorije Druge Panonije, praćeno sintezom danas dostupnih izvora, kao polazne tačke svih daljih istraživanja.</p> / <p>The thesis deals with religious history of Roman province Pannonia Secunda, formed in the southeastern part of the former province Pannonia Inferior within the administrative reforms of emperor Diocletian (284-305). The subject is chronologically limited to the 4th century in light of the fact that this period saw fundamental and far-reaching changes in the religious policy of the Late Roman Empire. It is a period of transition from the old Hellenic-Roman religion to freshly institutionalised Christianity. This century witnessed a paradoxical leap from the persecuted Christanity as religio illicita to the fully accepted Christianity as the only legitimate religion.<br />In the 4th century Pannonia Secunda became caput Illyrici not only of the newly-established prefecture Illyricum, but as the religious capital within the Metropolis of Sirmium. The increase of military and political importance of the province brought the Roman colony Sirmium a rank of imperial city, in which due to instability of the Lower Danube limes Roman emperors often dwelt. Consequently, Sirmium listed the greatest number of martyrs in comparison to the rest of Illyricum during the tetrarchic persecutions. Records of martyrdoms of Sirmian bishop Irenaeus, his deacon Demetrius, lector Pollio from Cibalae, Sirmian citizen Anastasia, gardener Syneros and many others became the core of the martyrological and hagiographical literature of Illyricum as well as the foundation for the study of Christian communities in Pannonia Secunda. First segment of the thesis studies this rich literary tradition, subjects it to historical criticism and corroborates it with archaeological evidence coming from the cult of these martyrs.<br />After legalization of Christianity, Sirmium became the main ecclesiastical see, which housed several church council from 349 to 378. These councils brought creeds that influenced Christological disputes in the entire state.&nbsp; Thus a significant segment of the thesis is concerned with the role of Pannonia Secunda in the Christological disputes from the Nicene council to the Council of Aquileia (325-381), analyzing Sirmian councils and formulas, the role of Valens of Mursa in homoian party, theology of Photinus of Sirmium and theological position of Germinius of Sirmium.<br />Chronologically the last theme is the period of Nicenian consolidation in the Council of Constantinople and the Council of Aquileia (381), where Sirmian bishop Anemius was active participant and a prot&eacute;g&eacute;e of the mighty Ambrose of Milan. However, this religious change in the religious affiliation of Pannonia Secunda&#39;s clergy and adherence to trinitarian theology, coincided with political and cultural disintegration of the province due to the collapse of the northern frontier and permanent barbarian settlement within its borders.&nbsp;&nbsp;<br />In view of significant archeological discoveries within the last five decades, the author dedicated a chapter to the material expression of religion of the Pannonia Secunda&rsquo;s population through forms of burial and cult architecture. The author also collected and analysed unpublished manuscripts relevant to reconstruction of Pannonian martyrology, along with some unpublished epigraphic material which bring beter understanding of religious life of the 4th century Pannonia Secunda.<br />The aim of the thesis was a comprehensive interdisciplinary study of the key period in the religious history of Pannonia Secunda accompanied with a synthesis of most significant sources as the basis for all future research.</p>

The coalfields of South Africa contain numerous dolerite intrusions, which are believed to have affected the quality of the surrounding coal by a thermal process, controlled by the size of the magmatic body. Data gathered from a working coalfield in Secunda, South Africa, suggest that the relationship between intrusive sills and coal is complex and factors other than intrusion width must be considered in relation to the contact metamorphic effect. The study area contains multiple dolerite intrusions of Karoo age, separated according to their geometric relationship to the local coal seams. Three intrusions were selected for detailed study. The three dolerite bodies, namely the DO4, DO8 and DO10 dolerites, occur as sills intruded close to the main coal seam of the area. The dolerite sills have identical mineralogy and can only be distinguished through textural variations in thin section. Coal quality data was obtained from Sasol Mining Secunda and used to investigate the presence or absence of a change in coal quality relative to dolerite proximity. Reduction in coal quality was defined using three main proximate analysis values, termed Ash, Volatile content (Vols) and Dry Ash Free Volatile (DAFV) in the coal industry. These parameters were used to determine the extent of any effect deleterious to coal quality induced by the intrusion of the dolerite sills. The resultant investigation showed no correlation between the position and thickness of the dolerites, and a change in coal quality (as measured by proximate analysis). In the absence of a linear relationship between coal quality and dolerite proximity, two processes are proposed to explain the absence of the contact metamorphic effects expected from previous studies: -Dolerite emplacement dynamics may influence the size of the metamorphic aureole produced by an intrusion, and invalidating intrusion size as a measure of thermal output, - Hydrothermal fluids mobilised by the dolerite intrusions, either from the country rock or the intrusion itself may percolate through the coal and act as the metamorphic agent responsible for changing coal quality, by dissolving the volatile components of the coal and transporting them to other locations These two processes are sufficient to explain the lack of a clear “metamorphic effect” related to the dolerite intrusions.

This study seeks to determine the effectiveness of detectives in the investigation of housebreaking cases in the Secunda Cluster. Key theoretical concepts such as criminal investigation, housebreaking, evidence and effectiveness, are defined and explained. The objectives of criminal investigation are discussed in detail. The elements of housebreaking are also explained in detail. The researcher`s findings were that the research questions were answered by all the participants, who had more than adequate knowledge on the concepts, and were sometimes in line with the literature. The researcher noted the problems identified by the participants and came up with some solutions. On the basis of the findings of this research, recommendations are made to have specialised training in the investigation of housebreaking cases. The clarification and application of the various investigation techniques to improve the effectiveness of the investigation of housebreaking cases were also recommended. Investigators should continually receive refresher in-service training on new techniques being used by criminals in committing residential housebreaking cases. / Police Practice / M. Tech.

<p>The study shows conclusively that brine composition and concentration is highly variable at these South African power utilities and processes such as RO, contact with ash and CO2 ingress can have an impact upon the overall brine quality. Aq.QA was found to be a more accurate tool for classifying waters according to dominant ions than Stiff diagrams but Stiff diagrams still have the superior advantage of being a mapping tool to easily identify samples of similar composition as well as quickly identify what has been added or what has been removed from a water stream. Chemical speciation could identify effluent streams where CO2 dissolution had taken place.</p>

Syftet med denna studie är att utforska och utveckla min förmåga att sjunga utryckfullt när det ges kort instuderingstid. Ambitionen är att förbereda mig inför ett så kallat sekunda vista-prov där gestaltning av text och musik är i förgrunden. Hur ser processen ut när jag försöker utveckla min förmåga att väva samman text och musik vid ett ge- staltningsprov med kort förberedelsetid? Under sammanlagt 6 veckor övades olika färdigheter rörande sekunda vista, prima vista, gehör, textlig och kroppslig gestaltning. Övningen skedde dagligen med stöd från en egen utformad lista: Träna intervall utan ord, sjunga intervall utan ord men med olika uttryck, sjunga korta melodifraser utan ord med olika uttryck, läsa korta fraser och gestalta texten, sjunga korta fraser och gestalta texten musikaliskt samt med en mobil-app kallad Ella. I slutet av varje vecka spelades en kortare tysk romans in där 40 minuter gavs som förberedelsetid. Roman- sen skulle för mig vara sedan tidigare helt okänd. I sammanfattningen av studiens ge- nomförande kan det konstateras att jag främst lägger fokus på att sjunga rätt toner, att sjunga med god sångteknik och att jag försöker få med ett kroppsligt uttryck vilket då blir på viss bekostnad av det musikaliska uttrycket. / The purpose of this study is to explore and develop my ability to sing expressively when given a short rehearsal time. The ambition is to prepare myself for a so-called secunda vista-test where the performance of text and music is in the spotlight. What does the process look like when I try to develop my ability to weave together text and music with very short preparation time? For a total of 6 weeks, various skills were practiced concerning secunda vista, prima vista, aural training, textual and physical ex- pression. The practice took place daily with the support of a prepared list: Practice intervals without words, sing intervals without words but with different expressions, sing short melodic phrases without words with different expressions, read short phrases and shape the text, sing short phrases, and shape the text musically, and with a mobile app called Ella. At the end of each week a short German lied was recorded where 40 minutes were given as preparation time. The lied was to me completely un- known before. In the summary of the study, it can be identified that my focus is mainly on singing the right notes, singing with good singing technique, and trying to get a physical expression, which then becomes at some expense of the musical expression.

Magister Scientiae - MSc / The objectives of this study were: To review and understand flow and transport processes in unsaturated zones. In this study, particular emphasis is placed on understanding mechanisms that cause non-uniform (preferential) flow for two casestudies, namely the Cape Flats sandy environment and the Mpumalanga Highveld fractured rock environment. To evaluate the adequacy of models, in particular MACRO 5.0, in simulating flow and transport in the vadose zone, by making use of two case study sites (Cape Flats and Mpumalanga Highveld). Of particular importance is the evaluation of transfer coefficients to represent fluid and solute exchange between macropores and matrix. To run a sensitivity analysis with MACRO 5.0 in order determine which input model parameters are the most relevant in describing the effects of preferential flow in water and solute transport.
