In general these ponds are not completly used and it potential is wasted. As it are disseminated at different places at cities it can reduce costs with water transport and permit water preservation of best quality. Some it utilities includes use in green areas irrigation, industrial among than cooling towers and boiler, soil compaction, cleaning urban road, pisciculture and fire fighting system. The quality these water is influenced by anauthorized sewage in the drainage system. This study was performed in six detention and infiltration ponds at drainage system of Natal, which aim was to verify the non-portable use these ponds on urban environment. As indirect aim would to incentive the water utilization these ponds as a water source to another uses in urban environment. These ponds represents the characteristics of detention and infiltration of Natal city and consequently of Brazil. As the water quality, the ponds presents following characteristics: three has apparently good quality, other showed intermediate condition and two had water polluted. Were performed twenty sample in each ponds and the following parameters assessed: pH, temperature, dissolved oxygen, turbidity, electrical conductivity, coliform thermotolerant, ammonia, organic nitrogen, TKN, nitrate, total phosphorus and alkalinity, bicarbonate, chloride, total hardness, calcium and magnesium hardness, total solids, TSS, TDS, COD and SAR?. To utilization on pisciculture we recommend use in ponds which presents the best quality. Only one pond presented higher pollutants and it not being appropriated for use in cooling tower. The content of solids suspension restricted the water use in all ponds in boilers. As water use in soil compaction, cleaning urban road and fire fighting system the water from these ponds are not appropriated. However, the recommended limits from literature are to domestic sewage, due to this, the parameters are restrictive to diminish the sanitary risk that could be offered with it utilization. The infiltration velocity of water these assessed ponds restrict a moderato use, however the effects are potentiated only in soil less sandy, which not occur in Natal. It is recommend the unrestricted irrigation utilization in ponds with best quality of water, and a restricted irrigation to ponds with worst quality of water. As load of pollutants, it is recommended a complementary treatment in those ponds whit higher load to diminish sanitary risks. In only one pond was found one helminth eggs and due to the convention formula of results, it was found for all ponds less than 1 helminth/liter eggs. / As lagoas de deten??o e infiltra??o do sistema de drenagem urbana geralmente possuem a fun??o de proteger a popula??o contra os efeitos indesej?veis de enchentes. Geralmente as ?guas de tais lagoas n?o s?o utilizadas e o seu potencial ? desperdi?ado. Por estarem disseminadas nas cidades pode-se reduzir os custos com transporte de ?gua, al?m de permitir a preserva??o de ?guas de melhor qualidade. Alguns dos poss?veis usos s?o irriga??o de ?reas verdes, uso em caldeiras, torres de resfriamento, e outros usos industriais, na compacta??o do solo, limpeza de vias p?blicas, na piscicultura, em sistemas de combate a inc?ndio, etc. A qualidade destas ?guas sofre influ?ncia de lan?amentos indevidos de esgotos sanit?rios na rede de drenagem. O estudo foi realizado em seis lagoas de deten??o e infiltra??o do sistema de drenagem de Natal, com o objetivo de verificar as condi??es de uso n?o pot?vel de suas ?guas no meio urbano. Indiretamente tamb?m objetiva incentivar a utiliza??o das ?guas destas lagoas como uma fonte de ?gua com potenciais de outros usos no meio urbano. As lagoas s?o representativas das caracter?sticas de lagoas de deten??o e infiltra??o que est?o disseminadas em Natal, assim como no Brasil. As lagoas apresentaram as seguintes similaridades: tr?s delas apresentaram aparentemente boa qualidade de suas ?guas, outra lagoa apresentou uma condi??o de qualidade intermedi?ria, e outras duas lagoas apresentam ?guas polu?das. Foram realizadas vinte coletas em cada lagoa de deten??o e infiltra??o. Os par?metros analisados foram: pH, temperatura, oxig?nio dissolvido, turbidez, condutividade el?trica, coliformes termotolerantes, nitrog?nio amoniacal, nitrog?nio org?nico, NTK, nitrato, f?sforo total, alcalinidade total, bicarbonatos, cloretos, dureza total, dureza de c?lcio, dureza de magn?sio, s?lidos totais, SST, SDT, DQO e RAS?. Para a utiliza??o em piscicultura recomenda-se o uso das ?guas das lagoas que apresentaram as melhores qualidades. Em torres de resfriamento apenas a ?gua de uma das lagoas, a que apresentou a maior carga de poluentes, n?o ? adequada. O teor de s?lidos em suspens?o restringiu o uso das ?guas de todas as lagoas em caldeiras. Para uso das ?guas das lagoas em compacta??o do solo, limpeza de vias p?blicas, e em sistemas de prote??o contra inc?ndio as ?guas das lagoas n?o s?o adequadas. Entretanto, os limites recomendados nas refer?ncias pesquisadas s?o para esgotos dom?sticos, e em fun??o disto, os par?metros s?o restritivos para que se diminuam os riscos sanit?rios que podem ser oferecidos com a utiliza??o. A velocidade de infiltra??o das ?guas das lagoas analisadas imp?s uma condi??o de uso moderado, mas os efeitos s?o potencializados apenas em solos pouco arenosos, que n?o ocorre em Natal. Recomenda-se a utiliza??o em irriga??o irrestrita para as ?guas da lagoa que possui a melhor qualidade, e, exceto para a de pior qualidade, a recomenda??o ? para uso em irriga??o restrita. Para as ?guas da lagoa com maior carga de poluentes recomenda-se tratamento complementar para que riscos sanit?rios sejam eliminados. Em uma ?nica lagoa foi encontrado apenas um ovo de helminto, e em fun??o das f?rmulas para convers?o dos resultados, foi encontrado para todas as lagoas a concentra??o de menos de 1 ovo de helminto/litro.

Les parois moulées sont des ouvrages de fondations en béton armé. Le béton de paroi moulée n'est jamais vibré et présente une fluidité élevée. Les observations effectuées après le terrassement et le rabotage des parois montrent que celles-ci présentent des défauts qui sont reliés au ressuage du béton lors de sa mise en place. Les cheminées de remontées d’eau représentent 90% des désordres observés sur les chantiers. Les constituants du béton sont souvent mis en cause. Une étude a été menée afin de comprendre l'influence des divers paramètres affectant le ressuage. Quatre formulations de béton issues de chantier ont été caractérisées en laboratoire. Une formule a montré sur chantier sa robustesse vis à vis du ressuage, tandis que les trois autres formulations ont abouti à des pathologies plus ou moins sévères. La formulation qui présentait le plus de pathologies a été modifiée de manière à observer l’effet des constituants de la formulation vis à vis du ressuage forcé et statique. Différentes pressions ont été étudiées afin de simuler différentes hauteurs de paroi moulée. Cette étude a permis de valider la pression 5 bars prédite par les recommandations Bauer. La formulation de base de ce béton de fondation a été modifiée de manière à obtenir une courbe granulaire continue, un rapport G/S proche de 1 et une augmentation du dosage en fines supérieur à 430 kg/m3. Les résultats des essais ont permis de limiter le seuil admissible du filtre presse Bauer à 15 ml au lieu de 24,4 ml. Les formulations du béton de fondation de plusieurs chantiers de parois moulées ont été modifiées, ce qui a permis de valider les prescriptions précédentes. Des recommandations ont pu être proposées. / The diaphragm walls are foundations made with reinforced concrete. The concrete of diaphragm wall is never vibrated and has a high fluidity. The observations recorded following excavation and planing of diaphragm walls demonstrate that defects are observed which are correlated with concrete bleeding during placement. Water upwelling pathology represents 90% of all disorders observed at project sites. Mix components are often implicated. A study was conducted to understand the influence of various parameters affecting the bleeding. Four concrete mix designs derived from the field were characterized in the laboratory. On a jobsite, one design has, revealed its robustness with respect to bleeding, whereas the other three have led to pathologies of varying severity. The tested concrete displaying the most of pathologies was modified so as to observe the effect of different mix components on the forced and static bleeding. A range of pressures was introduced as a means of simulating various diaphragm wall heights.This study validated the pressure 5 bar predicted by the Bauer recommendations. The basic formulation of this concrete of foundation has been modified in order to have a continuous granular curve, G / S close to 1 and an increasing in the dosage of fines greater thinly than 430 kg / m3. The results of tests served to limit the admissible threshold of filter press Bauer at 15 ml instead of 24,4 ml. The formulations of the concrete foundation of several diaphragm walls have been modified accordingly, which validated the previous prescriptions. Recommendations have been proposed.

This thesis deals with the conservatively authoritarian collaboration movement led by the so-called State President of the Protectorate of Bohemia and Moravia, Emil Hácha, who belongs to the controversial figures of our modern history. The thesis is concerned with Hácha's ideological orientation as a radical conservative and with the historicist concept of the Czech statehood as the two main bases of his approach to collaboration on whose grounds the policy of actual cooperation with the Nazi occupiers was realised. In connection with Hácha's specific type of collaboration, emphasis is placed on his negative relationship with the first independent Czechoslovak Republic and its liberal democratic regime, and, on the other hand, on his friendly relationship with the Greater German Reich and supra-state systems in general. In order to demonstrate the practice of E. Hácha's policies, attention is paid to the President's and his supporters' loyal pro-German speeches, activities of the organisations founded by Hácha -- Národní souručenství (National Community) and Český svaz pro spolupráci s Němci (Czech Union for Cooperation with Germans) -- and Hácha's attitude towards the Czech resistance movement. The thesis also depicts the change of Hácha's leading position in the autonomous administration of the Protectorate in connection with the Nazi intentions that were put into practice in the Czech area from his election to the end of the war. Another aim of the thesis, in order to assess in detail the form of the President's pro-German cooperation, is to compare Hácha's group with the Czech fascist movement, and the collaborating journalists around E. Moravec. The primary focus is on the ideological conflict and political struggle for power among the collaborative movements, their different attitudes to the German occupation administration, and their exploitability by Nazi policies in the Protectorate. The final part of the thesis deals with opinions of contemporary society on E. Hácha's Protectorate policies, including reactions of the resistance at home and abroad. On this basis, the post-war statements given by the representatives of Hácha's collaboration movement to the National Court in the process of "national cleansing" are compared with their actual activities during the time of the occupation. The thesis draws from archive materials, contemporary printed sources, and scholarly literature that covers the topic of collaboration in the Protectorate.

Cette étude vise à caractériser des fragments clés d’une interface de subduction fossile affleurant dans la Ceinture Métamorphique du Sud-Tianshan (Chine). Nous étudions les processus de subduction au travers de la profondeur critique de ~80 km, au-delà de laquelle la géophysique et les modèles prévoient un changement du couplage mécanique, et les roches océaniques ne sont normalement pas exhumées. Ce travail s’intéresse au Complexe Métamorphique Akeyazi (AMC), un épais empilement de roches métavolcanoclastiques enveloppant des écailles éclogitiques, exposé sur ~30 km dans la vallée de Kebuerte, et préservant de nombreuses reliques de coésites. L’étude structurale révèle que l’AMC est un dôme métamorphique consistant de plusieurs nappes cohérentes d’ampleur kilométrique avec des histoire P-T-t-d distinctes. 4 unités sur 6, i.e. UH (2.75 GPa/480-560°C), EB (2.1/505), MU (1.45/485) et GT (>0.7-1.0/470-520) ont été subduites à des profondeurs de ~85, 65, 45 et 30 km respectivement. La déformation rétrograde des unités, liée à leur exhumation, est caractérisée par des bandes de cisaillement top vers le Nord au faciès schiste bleu. Le pic d’enfouissement de ces unités a eu lieu à 320±1, 332±2, 359±2 et 280-310 Ma pour les unités UH, EB, MU et schiste vert, indiquant plusieurs courts épisodes de détachement de matériel de la plaque plongeante. L’évolution tectono-métamorphique de ~12 à 5-7°C/km au cours du temps peut refléter le refroidissement progressif de la subduction. La juxtaposition et l’exhumation à 1-3 mm/an de ces 4 unités à des profondeurs crustales a eu lieu autour de 290-300 Ma. / This study attempts to characterize key fossil fragments of material equilibrated along subduction plate boundary, now exposed in Chinese SW-Tianshan Metamorphic Belt (STMB). We herein elucidate some subduction zone processes across a critical depth range of ~80km, beyond which geophysicist and modeler infer a change in mechanical coupling and oceanic rocks are usually not recovered. It focuses on an unusually thick pile of HP/UHP metavolcanoclastics, wrapping eclogite slices and preserving pervasive coesite relics, along a ~30km-long transect across the Akeyazi metamorphic complex (AMC) in the Kebuerte valley. Structural studies reveal the current geometry of the AMC is a metamorphic dome with evidence of internal nappe stacking and should be subdivided into several coherent, km-scale tectonic units with distinct P-T-time-deformation histories. At least 4 of 6 sub-units identified here, i.e., the UH (2.75 GPa/480-560°C), EB (2.1/505), MU (1.45/485) and GT units (>0.7-1.0/470-520) were subducted and buried to depths of ~85, 65, 45 and 30 km respectively. Deformation following EC/BS-EC peak burial is marked by pervasive BS facies exhumation-related shear senses with a top to North component. Radiometric constraints yield peak burial ages of 320±1, 332±2, 359±2 and 280-310 Ma, respectively, for the UH, EB, MU and GS facies units, indicating several short-lived detachment episodes of material from the downgoing plate. The tectono-metamorphic evolution from ~12 to 5-7°C/km with time may reflect progressive cooling of the subduction system. Juxtaposition & exhumation of those 4 units to mid-crustal depth, at rates on the order of 1-3 mm/yr, was accomplished around 290-300Ma.

This master thesis deals with the development of the academic relations between the Czechoslovak Socialist Republic and the Federal Republic of Germany during the so-called normalization, so from the beginning of the 1970s to the fall of the so-called Iron Curtain. The main focus lies on the inter-university partnership between Charles University in Prague and the University of Hamburg, which was concluded in Prague in 1980 and is successfully carried out till today. It was the first cooperation agreement Charles University made with a West German university during the period of the cold war. The thesis analyses, in which way both universities approached the partnership and how the cooperation could be put into practice. The main objective of the text is to find out which dynamics the partnership in the observed period gained and if the cooperation even managed to overcome the original expectations of the main actors considering the given conditions within the domestic and international politics. The examined cooperation is put into a broader context, not only of the development of the Czechoslovak-West German relations but also of the situation within international politics. The partnership was possible to negotiate thanks to bilateral agreements, which arranged the further development of the...

Effective Governance of Enterprise Information Technology (GEIT) is very important for an enterprise that has a huge investment in IT infrastructure. Implementing effective GEIT helps an enterprise to meet stakeholder needs by creating business value through strategic business-IT alignment. This study focuses on the analysis of GEIT implementation related to strategic business-IT alignment using Control Objectives for Information and Related Technology (COBIT 5), using the Commercial Bank of Ethiopia (CBE) as a case study. Strategic alignment is found to be the main concern of GEIT and strong alignment between business objectives and IT capabilities as a means of creating an effective foundation for business execution. There are various internationally accepted GEIT good practices and standards. In this study, COBIT 5 is selected for its strong aspects of control objectives for strategic business-IT alignment that help enterprises’ security, risk and compliance guidance and serves as a tool for leveraging GEIT. COBIT 5 is the leading business framework for the GEIT by making clear that there is a separation between governance and management of IT. This is a single integrated framework that covers the enterprise holistically and integrates with other important frameworks and standards at an advanced level. In addition to this, the use of COBIT 5 Balanced Score Card (BSC) for performance measurement tool (goals cascade), Process Reference Model (PRM), Process Assessment Model (PAM), principles and enablers and Capability Maturity Model (CMM) tool also utilise IT investments more effectively and accurately and measure performance with lower costs through stronger governance. This study analysed how enterprises effectively implement GEIT practices using COBIT 5 to achieve strong strategic business-IT alignment. The target groups of the study were the top management and IT management of CBE. The researcher used explanatory sequential mixed methods (both quantitative and qualitative) data collection techniques and analysis procedures. In the quantitative data collection, data were collected and analysed using GEIT practices maturity assessment tool, Luftman Strategic Alignment Maturity Model (LAMM) tool and the data analysed using Statistical Package for the Social Science (SPSS). In the qualitative phase of the study, evidence was collected and examined from observation and participation, document review, focus group, formal and informal discussions with selected managements of CBE and gap assessment using COBIT 5. Finally, the researcher integrated results to combine the quantitative and qualitative methods. The finidngs of the quantitative analysis indicate that the maturity level of GEIT practices implementation was 1.77, around level 2 maturity level (repeatable but intuitive), whereas the business-IT alignment maturity level of 53.13% agrees that strategic alignment business-IT was good level 3 (established, focused processes) in the case of CBE. GEIT practices implementation regarding strategic business-IT alignment is found to be positive. The data qualitative analysis indicates that the achievement of the capability level of GEIT processes is not defined and deployed based on international best practices and also confirms that the GEIT BSC is not yet implemented. The achievement capability level of GEIT processes implementation using COBIT 5 is under level 2. In this study, the gap between the existing GEIT practices processes and desirable level 4 (managed and measurable) using COBIT 5 was identified and a method to fill the gap was proposed. / School of Computing / M.

The subject of this thesis is to record the every-day life, local and collective memory, and relationships of individuals - local inhabitants of the 'panel-housing' estate, Jižní Město, in Prague - towards the specific urban and social space in which they live. The thesis is based on interviews, with the long-term inhabitants of Jižní Město, which were structured to record their lived experience in the housing estate during two consecutive periods in recent Czechoslovak history - the so-called normalisation and post-socialism periods. The interviews were used as an empirical counterbalance to architectural/city planning discourse and Czech media, which has interpreted the legacy of 'panel-housing' estates in a negative way, as the socialist form of housing par excellence. The aim of this thesis is to analyse this discourse, which also reflects how Czech society deals with its communist past, and to compare it with the experiences, evaluations and current challenges in the lives of these long- term inhabitants, living in the biggest Czech 'panel-housing' estate with a bad reputation. Key words: panel-housing estates, Jižní Město, housing, local/collective memory, local/urban identity, everyday life, city, so-called normalisation.

This thesis focuses on the quality of life in dimension of health at the regional level in the Czechia for the period 2010-2019. The main aim of this work is to describe and evaluate the spatial differentiation and spatio-temporal variability of the concept quality of life in dimension of health at the regional level of administrative districts of municipalities with extended powers. The assessment is based on objective indicators mapping the health status of the population, lifestyle, and the availability of primary health care. The theoretical part describes definitions quality of life, the characteristics of whole concept, health, its determinants, and inequalities that arise in health and can resonate at the regional level. This work also describes the types of prevention, as an effective tool in reducing health inequalities and the possible promotion of public health, in the form of improving health literacy. The analytical part is based on factor and cluster analysis and methods of spatial autocorrelation. In the Czech Republic, significant regional differentiation of quality of life in health dimension has been found. Furthermore, spatial patterns were discovered drawing attention to problematic and favourable areas within the observed concept. It turned out that the resulting quality of...

The interplay of experiments and theory is essential to deepen our understanding of magnetization dynamics. This thesis aims to serve as a bridge between these two aspects by establishing a mathematical framework that enables the computation of optical observable quantities based on theoretical models. The equations are cast in a matrix representation that is well-suited for performing numerical simulations. Additionally, the generality of these methods enables their application to layered media with any geometry, regardless of whether they possess magnetic properties or not. Furthermore, it explores the various perspectives and physical mechanisms involved in magneto-optic measurements to provide the reader with a self consistent introduction to the subject matter. Numerical calculations are presented for bulk Fe, alternating layers of Fe/Au and Ni with a MgO coating and a SiO substrate for different energies, angle of incident and magnetization direction. The results demonstrate the effectiveness of the method in predicting measurable outcomes from theoretical considerations and enables the analysis of optimal experimental configurations. / Samverkan mellan experiment och teori är avgörande för fördjupa vår förståelse av magnetiska system och deras dynamik. Målet med denna uppsats är att etablera en koppling mellan dessa två aspekter genom att formulera ett matematiskt ramverk som möjliggör beräkningar av optiska observerbara storheter baserat på teoretiska modeller. Ekvationerna formuleras med matriser vilket är väl lämpat för att utföra numeriska simuleringar. Dessutom möjliggör metodens generella natur tillämpning på skiktade material av godtycklig geometri, oavsett om de har magnetiska egenskaper eller inte. Vidare utforskar uppsatsen olika perspektiv och fysikaliska mekanismer som är involverade i magneto-optiska mätningar för att ge läsaren en självständig introduktion till ämnet. Numeriska beräkningar presenteras för bulkjärn, växlande lager av Fe/Au och Ni med en MgO-beläggning och ett SiO-substrat för olika energier, infallsvinkel och magnetiseringsriktning. Resultaten visar på metodens förmåga att förutsäga mätbara resultat baserat på teoretiska överväganden och tillåter analys av optimala experimentella uppställningar.
