Il metodo dei cronometri cosmici consente di misurare H(z) attraverso la datazione differenziale delle età delle popolazioni stellari delle galassie "early-type" massive e passive, che assumono il ruolo di “orologi standard” nell'Universo. Questo lavoro di tesi è incentrato sulla selezione di un campione ottimizzato di "orologi standard" a partire dagli spettri della survey spettroscopica ad alta risoluzione LEGA-C, in quanto una buona selezione consente di ridurre e tenere sotto controllo gran parte degli errori sistematici sulle stime di H(z). La prima parte della tesi descrive la selezione delle galassie effettuata a partire dagli spettri della Data Release 2 della survey, tramite l'uso simultaneo di tre criteri diagnostici (fotometrico, spettroscopico e ispezione visuale degli spettri), che ha fornito un campione di 245 "orologi standard" di cui si sono analizzate anche le proprietà fisiche. Nella seconda parte della tesi, l’analisi è stata svolta su un campione di 65 "orologi standard" estratti dalla Data Release 1 della survey, e si è incentrata sullo studio di diagnostici in grado di quantificare il livello di contaminazione residua da parte di una popolazione giovane sottostante la popolazione vecchia dominante che, se non è opportunamente tenuta in considerazione, può inficiare la stima di H(z) fino ad un valore del 20%. Si è quindi analizzata l'emissione ultravioletta nelle SED fotometriche, dimostrandone la trascurabilità. Si è poi applicato il metodo diagnostico spettroscopico basato sul rapporto delle righe del Ca II H/K per la prima volta a dati reali, sia misurandolo come rapporto tra i minimi delle righe, sia formulandone una nuova definizione basata sul rapporto integrale tra le due righe, tramite le misure di due nuovi "pseudo" indici di Lick da noi definiti. Si è quindi quantificata la contaminazione sul campione di "orologi standard" tramite un confronto con andamenti teorici dei rapporti H/K derivati da una libreria di spettri sintetici.

Since the collapse of the bubble economy in 1990, Japanese securities houses have suffered serious damage and have not been able to keep up with the progress of the global investment banking industry. During this period, foreign investment banks have grown rapidly, diversified the coverage of business, and expanded to the global market. Japanese investment banks were first developed in the late 1990s, after the "lost decade". They have competed with Japanese and foreign rivals mainly in the domestic market. This thesis explores both the external and internal strategic challenges confronting a Japanese investment bank seeking to survive and become a global player in the industry. First it confirms the findings of a recent stuffy of the Japanese investment banking industry and then explores two key lessons learned from historical experience in U.K. and U.S. financial markets. The current policy of Japanese government is also reviewed. With regard to the analysis of future challenges of Japanese investment banks, this thesis employs the game approach to understanding external challenges while the learning approach is applied to better understand internal challenges.

ENGLISH ABSTRACT: Background: Misoprostol, a prostaglandin E1 analogue with its uterotonic properties has entered as an integral part of management of the third stage of labour, helping to prevent postpartum haemorrhage (PPH). Objective: To assess evidence on the effectiveness of misoprostol compared to a placebo for the prevention and treatment of postpartum haemorrhage. Methods: Databases searched included; MEDLINE, Google Scholar and Cochrane Central Register of Controlled Trials (CENTRAL). Other sources were also searched. All articles were screened for methodological quality by two reviewers independently by standardized instrument. Data was entered in Review Manger 5.1 software for analysis. Results: Three Misoprostol studies were included (2346 participants), Oral (2 trials) and sublingual (1 trial). Misoprostol has shown not to be effective in reducing PPH (RR 0.65: 95% CI 0.40-1.06). Only one trial reported on need for blood transfusion (RR 0.14; 95% CI 0.02-1.15). Misoprostol use is associated with significant increases in shivering (RR 2.75; 95% CI 2.26-3.34) and pyrexia (RR 5.34; 95% CI 2.86-9.96) than with placebo. No maternal deaths were reported in included trials. Compared to placebo, misoprostol was coupled with less hysterectomies and additional used of uterotonics (RR 0.45; 95%CI 0.21-0.96) compared to placebo. Conclusion: Results of this review shows that the use of misoprostol in combination with some components of active management was not associated with any significant reduction in incidence of PPH. However oral administration showed a significant reduction in incidence of PPH. For its use for treatment of postpartum haemorrhage, there is a need for research focus in optimal dose and route of administration for a clinically significant effect and acceptable side effects.
AFRIKAANSE OPSOMMING: Agtergrond: Misoprostol, 'n prostaglandien E1 analoog met sy uterotonic eienskappe het ingeskryf as' n integrale deel van die bestuur van die derde stadium van kraam, help postpartum bloeding (PPH) te voorkom. Doelwit: Om bewyse oor die effektiwiteit van Misoprostol in vergelyking met 'n placebo vir die voorkoming en behandeling van postpartum bloeding te evalueer. Metodes: Databases gesoek ingesluit, Medline, CINHAL, Google Scholar en Cochrane Sentrale Register van gecontroleerde studies (Sentraal). Ander bronne is ook deursoek. Alle artikels is gekeur vir die metodologiese kwaliteit deur twee beoordelaars onafhanklik deur die gestandaardiseerde instrument. Data is opgeneem in Review Manger 5.1 sagteware vir ontleding. Hoof Resultate: Drie Misoprostol studies were ingesluit (2346 deelnemers). Mondeling (2 proe) en sublinguale (1 verhoor). Misoprostol het getoon nie doeltreffend te wees in die vermindering van PPH (RR 0,65: 95% CI 0,40-1,06). Slegs een verhoor berig oor die noodsaaklikheid vir 'n bloedoortapping (RR 0,14, 95% CI 0,02-1,15). Misoprostol gebruik word geassosieer met 'n aansienlike toename in bewing (RR 2,75, 95% CI 2,26- 3,34) en koors (RR 5,34, 95% CI 2,86-9,96) as met' n placebo. Geen moederlike sterftes is aangemeld in proewe. In vergelyking met placebo, was Misoprostol tesame met minder hysterectomies en addisionele gebruik van uterotonics (RR 0,45, 95% CI,21-,96) in vergelyking met placebo. Gevolgtrekking: Resultate van hierdie studie toon dat die gebruik van Misoprostol in kombinasie met 'n paar komponente van aktiewe bestuur is wat nie verband hou met' n beduidende afname in die voorkoms van PPH. Vir die gebruik vir die behandeling van postpartum bloeding, daar is 'n behoefte vir navorsing fokus in die optimale dosis en die roete van administrasie vir' n klinies beduidende uitwerking en aanvaarbare neweeffekte.

Resumo:
This Thesis presents ethnographic data collected through multi-sector, multi-level purposive sampling in a longitudinal qualitative case study between 2008 and 2010. A pilot study had discovered the changing role of government in building capacity for responses to civil emergencies, against a context of changing risks and resources for UK Emergency Management. The Thesis explored the increasing involvement of non-statutory agencies by focussing on the ‘Third Sector’: voluntary, charitable, faith, or community organisations and communities. The Thesis reports (1) the relationship between multi-organisational arrangements and resilience, (2) the role of Third Sector organisations in implementing resilience, and (3) the role of the Third Sector in community resilience. (1) The data suggested that the process of implementing resilience involved operationalising the resilience concept as a philosophy for Integrated Emergency Management [IEM], and consequent changes to the governance and organisation of Scottish and UK emergency management. The research linked the role of the Third Sector in resilience and community resilience to the dynamic between preparedness and response. It explored (2) the impact of implementing resilience on organising and organisations in the Third Sector, and (3) policy development and capacity-building for an emergent role in community resilience. The Thesis makes a distinctive contribution to the discipline of Public Management. Firstly, the findings represent a novel empirical and theoretical contribution regarding the role of the Third Sector in community resilience and in the resilience paradigm of emergency management. This data is used to extend existing theory about the proactive role of Third Sector organisations in collaborative emergency management. Secondly, the Thesis argues that the meso-level of analysis is neglected in the emerging field of resilience studies. Network and collaboration theory in Public Management are used to make a novel theoretical contribution, describing the relationship between multi-organisational arrangements and the operationalisation of ‘resilient’ emergency management. Thirdly, the Thesis contributes to the study of collaborative emergency management from this longitudinal perspective. This data is used to extend our understanding of (a) the applicability of Public Management theory to this context and (b) the relevance of data from this context to theories of collaborative public management.

A dor pós-operatória é a causa mais comum de hiperalgesia em humanos e pode ter sua severidade e duração reduzidas através da analgesia preemptiva, tratamento antinociceptivo que previne o processamento alterado de impulsos nervosos responsáveis pela sensibilização central. A literatura sugere que o uso pré-operatório de anti-inflamatórios pode diminuir a intensidade e a duração da dor pós-operatória. Dezenove participantes submetidos à extração de terceiros molares inclusos inferiores bilaterais participaram de ensaio clínico randomizado, duplo-cego, cruzado, no qual foi comparado o uso de dose única (DU, 600mg de ibuprofeno, VO, 1 hora antes da cirurgia) versus doses múltiplas (DM, 600mg de ibuprofeno 25, 19, 13, 7 e 1 hora antes da cirurgia). O desfecho principal foi a redução da dor pós-operatória, medida pelo uso da escala visual analógica (EVA) aplicada imediatamente e 3, 8 e 24 horas após a cirurgia. Como desfechos secundários utilizaram-se a medida da redução do grau de abertura bucal 24h pós-cirurgia, o consumo de analgésico socorro (Codeína 30mg, VO) nas 24h pós-cirurgia e a aplicação dos filamentos Semmes-Weinstein (Δlog força g). O grupo DM apresentou menor intensidade de dor (EVA) quando comparado com o controle nos tempos 3h e 8h após a cirurgia (22  21 vs. 37  29; 27  22 vs. 37  34; DM VS DU, 3h e 8h respectivamente, P = 0,03). Não houve diferença com relação aos desfechos secundários. Em conclusão, o uso de doses múltiplas foi superior ao uso de dose única de ibuprofeno na analgesia preemptiva associada à cirurgia de remoção de terceiros molares inferiores inclusos.
Postoperative pain management still represents a challenge for some clinicians, and its severity and duration can be reduced by preemptive analgesia, defined as an antinociceptive treatment that prevents the establishment of altered central processing of afferent input, responsible by amplification of postoperative pain. Nineteen participants underwent extraction of bilateral lower impacted third molars were enrolled in a randomized clinical, double-blind, crossover clinical trial, which was compared using single dose (SD, 600mg of ibuprofen, oral, 1 hour before surgery) versus multiple doses (MD, 600 mg ibuprofen 25, 19, 13, 7 and 1 hour before surgery). The primary outcome was reduction of postoperative pain, measured by using a visual analogue scale (VAS) immediately and 3, 8 and 24 hours after surgery. Secondary outcomes were reduction of degree of mouth opening, consumption of rescue analgesics (codeine 30 mg, orally) and measurement of the pain threshold by Semmes-Weinstein filaments application (Δlog force g), 24 hours after the surgery. The MD group showed less pain (VAS) compared with the control at 3 and 8 hours after surgery (22±21 vs. 37±29, 27±22 vs. 37±34; MD vs. SD, 3h and 8h respectively, P = 0.03). There was no difference with respect to the secondary outcomes. In conclusion, the use of multiple doses is superior to single dose of ibuprofen as preemptive analgesia strategy associated with surgical removal of impacted lower third molar.

The synthesis of steroidal 14α,16-methano, 14α,17-methano-, 14α,17-ethano- and 14α,17-propano estradiol analogues as well as 14α-alkyl and 14α-functionalised-alkyl estradiol analogues was investigated. Furthermore, the synthesis of 17β-hydroxy-17α, 14-(epoxymethano)androst-4-en-3-one was undertaken and acid-mediated rearrangement of the 14,17-etheno bridged testosterone analogue gave the 14,16-ethano analogue of androst-4-en-3,17-dione. Established ring D cycloaddition and oxidative cleavage methodology gave ring D 14α-formyl and 14α, 17α-diformyl compounds as key intermediates in the overall synthetic plan. Chemoselective- and stereoselective nucleophilic addition at C-14¹ of the 14α-formyl-3-methoxyestra-1,3,5(10)-trien-17-one provided access to 14α-alkyl- and 14α-alkyl-functionalised 19-norsteroids for elaboration toward 14α,17-propano- and 14α-alkylamide estradiol analogues. Synthesis of the 14α,17-methano bridged steroid was attainable indirectly through intramolecular pinacol coupling between the 17-oxo- and 14-formyl group of 14αformyl- 3-methoxyestra-1,3,5(10)-trien-17-one. The 14α, 16-methano bridged steroid was synthesised via base-mediated intramolecular cyclisation of 14-(toluene-p-sulfonyloxy)methyl-3-methoxyestra-1,3,5( 1 0)-trien-17-one. Novel compounds were characterised with the aid of high field NMR techniques. A X-ray crystal structure determination of the strained ring D 14α, 17-methano bridged estriol analogue corroborated its structure. The minimum energy conformation of novel estradiol analogues were superimposed on estradiol, and their least square fit values determined and discussed in relation to biological activity. These analogues will contribute toward defining the structural parameters responsible for certain pattern of hormonal activity, and hence, the ultimate goal of predictive drug design.

La presente investigación propone que la novela Mañana, las ratas (1984) de José B. Adolph es una novela de ciencia ficción inscrita en la tradición de la utopía andina, que presenta al neoliberalismo aplicado en el Perú como una utopía de la igualdad destinada a fracasar, que se contrapone con las utopías que a la vez imaginan otros grupos de poder y las personas marginadas durante siglos por una sociedad que no es capaz de desvincularse de su pasado colonial. Para demostrar esta hipótesis, estudio de qué manera la novela se inscribe en las tradiciones de la utopía y la distopía, y sus diferentes variantes, en el marco de los planteamientos de Fredric Jameson, Alberto Flores Galindo, George Claeys y Gabriel Alejandro Saldías. También, en la medida en que la distopía se vale de algunos elementos de la ciencia ficción para lograr el extrañamiento necesario para la crítica, utilizaré la propuesta teórica de Marco Suvin, así como los acercamientos a la historia del género de la ciencia ficción latinoamericana de Luis Carlos Cano y Elton Honores. Asimismo, de manera transversal, analizaré, en el marco de la propuesta teórica de Mijail Bajtín, cómo los diversos cronotopos de la novela reflejan las condiciones distópicas de esta sociedad. Entre las condiciones que me interesan analizar se encuentran las prácticas y discursos ideológicos que movilizan la deshumanización de la población de la clase baja, denominadas «las ratas», con el fin de mantener el poder de quienes gobiernan; por lo que, tomando como punto de partida los conceptos del homo sacer, de Giorgio Agamben, la basurización, de Rocío Silva Santisteban, y de la arcadia colonial, de Sebastián Salazar Bondy, analizo el retrato de la deshumanización de las ratas, a quienes se ha despojado de sus derechos ciudadanos, en una Lima declarada en estado de excepción constante.

Mestrado em Comunicação Multimédia
O jornalismo de proximidade caracteriza-se por promover uma diferente forma de comunicar. A informação difundida pretende, mais do que dar a conhecer uma situação, fazer com que o público se sinta parte dela, estabelecendo, assim, uma relação baseada no interesse comum. Quando utilizado como veículo um meio de comunicação tão abrangente como a televisão e um género informativo com as características ímpares da Reportagem, todas as particularidades do jornalismo de proximidade saem reforçadas. Para além disso, numa era marcada pela globalidade e ausência de fronteiras, torna-se pertinente perceber a importância dada ao local. Neste sentido, o presente trabalho tem como principal objetivo identificar as guidelines da reportagem de proximidade, tendo como base o estudo de caso das reportagens emitidas no Porto Canal. Para atingir o objetivo, o investigador esteve durante quatro meses nas instalações da estação televisiva e desempenhou as várias tarefas inerentes à criação deste género jornalístico, conseguindo, assim traçar as diferentes linhas orientadoras de uma reportagem construída neste contexto, atendendo às diferentes fases do processo de construção: Produção, Realização e Pós-
Local journalism is characterized by promoting a different way to communicate. The information disseminated aims to - more than make known a situation - make the audience feel part of it, thus establishing a relationship based on common interest. When used as a means of communication as broad as television and an informative gender with the unique characteristics of the news report, all the characteristics of local journalism are reinforced. Besides, in an era marked by globality and an absence of borders, it is pertinent to realize the importance given to the local itself. In this sense, this work has as main objective to identify the guidelines of the news report at a proximity level, based on the case study of news reports broadcasted by Porto Canal. To achieve the objective, the investigator spent four months in the facilities of the television station and performed various tasks involved in the creation of this journalistic genre, having achieved the different guidelines of a story built in this context, taking into account the different stages of the construction process: production, implementation and post-production.

Resumo:
Soil is an invaluable finite resource, and it is essential that any changes in soil condition are adequately monitored. In the semi-arid regions of eastern Australia, there has been an expansion of intensive irrigated cotton production, and these regions have also experienced highly variable rainfall patterns in the last decade or so. This combination of climatic and land use changes has the potential to significantly alter soil attributes. This thesis focuses on monitoring the change in several important soil properties – pH, salinity, sodicity, and organic and inorganic carbon – in the semi-arid irrigated cotton-growing district of Hillston, NSW, between 2002 and 2015. Rather than using traditional digital soil mapping techniques, this study focuses on using bi- and multi-variate linear mixed models, and two-step mixture models to model and map soil properties in space and time. The linear mixed models were particularly advantageous for monitoring changes in soil properties as they can account for correlation in space and time, and improve the sensitivity of detecting statistically significant changes. As traditional laboratory methods of measuring certain soil properties can be expensive and laborious, this study also focused on using visible near infrared (VisNIR) spectroscopic techniques to rapidly predict exchangeable sodium percentage (ESP), organic carbon (SOC) content, and inorganic carbon (SIC) content. Various degrees and extents of soil change were observed during the study period in both the top and sub soil. This included an acidification trend in some areas, a contrasting shift in electrical conductivity (EC) under differing land uses, an increase in soil ESP under irrigated land uses, an increase in SOC content at some locations, and no detectable change in SIC content. Overall, it was clear that fluctuating rainfall patterns and agricultural management practices had a notable impact on the degree and direction of changes in soil properties.

Resumo:
H2O and CO2 concentrations in olivine-hosted melt inclusions, assuming vapor saturation at the time of trapping, can be used to estimate crystallization depths for the olivine host. Estimating the true CO2 in melt inclusions is difficult, as much is lost to shrinkage bubbles, which form upon post-entrapment cooling and crystallization. Reheating olivine to temperatures above the melt inclusion trapping temperature and then quenching rapidly can restore CO2 to the glass because the CO2 in the bubble redissolves at high temperature. Previous work has established that olivine crystallization for the1959 Kilauea Iki eruption took place in the shallow summit reservoir, but crystallization depths have not been established for the rift extension of the eruption, at Kapoho. The new data presented here suggest that the most primitive Kilauea Iki component bypassed the summit reservoir for the east rift zone prior to the start of the eruption and was later erupted at Kapoho.

У витоках цих гобеленів – звичайно багата культура, сакральна символіка, національні мотиви і народні традиції України. Проте особливим резонансом відгукнулася виставка художниці під назвою "Лабіринт", що пройшла у львівській галереї сучасного сакрального мистецтва "Іконарт" у 2018 році. Ця несподівана виставка здивувала своєю винятковістю, неординарністю, адже всі свої роботи авторка зашифрувала у сучасні QR-коди, що являють собою невід'ємні актуальні цифрові елементи сучасного світу.
In this paper, the author analyzes the artistic search of a talented craftswoman from Lviv, Yaroslava Tkachuk, who uses rare techniques and uses innovative methods of weaving – "weaves tapestries from metal." The origins of these tapestries are usually rich in culture, sacred symbols, national motifs and folk traditions of Ukraine. However, the exhibition of the artist called "Labyrinth", which took place in the Lviv gallery of contemporary sacred art "Ikonart" in 2018, had a special resonance. This unexpected exhibition surprised with its uniqueness, extraordinaryness, because the author encrypted all her works into modern QRcodes, which are integral relevant elements of the modern world.

Svensk dramadialog under tre sekel är ett projekt framtaget vid Uppsala universitet och innehåller en dramakorpus av 45 pjäser från 1725–2000. Syftet med den här undersökningen är att undersöka utvecklingen av tilltal i fyra pjäser med utgångspunkt i fyra dramer ur Svensk dramadialog under tre sekel. Undersökningen har sin utgångspunkt i tilltalen du och Ni men andra tilltal som exempelvis titlar, förekommer. Undersökningen visar att samtidens tendenser för tillatalsbruk speglas i de fyra pjäserna mellan 1925 och 1997 och att miljöer och sociala förhållandena avgör vilket tilltal som används. Undersökningen visar även att författarna till dessa pjäser har möjlighet att använda tilltalet som en stilistisk resurs för att visa relationer mellan personer inom pjäsen. Undersökningen speglar även du-reformen och en utveckling av ett artigt nyniande som ersatt Ni.

I denna undersökning granskas 31 texter skrivna av elever i årskurs 7 höstterminen 2011. Samtliga texter är skrivna efter samma på förhand fastställda uppgift. Metodmässigt har texterna granskats genom en närläsning strukturerad av ett analysschema.  Undersökningen syftar till att besvara följande frågeställningar: - Vilka är de texttypsmässiga styrkorna och svagheterna i elevtexterna? - Hur ser samspelet ut mellan berättandet och argumenterandet i elevtexterna? - Vilka typer av kunskaper i argumentation visar sig i elevtexterna? Sammanfattningsvis visar studien att eleverna kan föra fram en tes och argument som stödjer tesen. Dock finns det utrymme för förbättring vad det gäller skapandet av disposition. Undersökningen visar också att en mindre del av eleverna valde att skriva en diskuterande text istället för en renodlad argumentation. Eleverna har i de flesta fall en god känsla för blandningen av den argumenterande och berättande texttypen. I diskussionen redogörs för hur texterna skulle kunna användas i ett formativt arbetssätt för att diskutera kunskaps-kvalitéer.
In this thesis 31 student texts are examined by close reading. The texts were written in seventh grade on the fall semester of 2011. The study of close reading were structured by an analytic scheme and aimed to answer the following questions: - Which are the strengths and weaknesses in the student’s text in relation to text type? -  How is the relationship between narrative and argumentative text types represented? -  Which signs of knowledge about written argument appear in the student’s texts?  The study shows that most students can formulate a thesis and argument to support it.   There is however room for improvement when it comes to the disposition of the text. The study also shows that some of the students wrote a text as a discussion rather than an argument. In most cases the students are successful in combining narrative and argumentative text types. The thesis is concluded by a discussion about how these results could be helpful in the frame of formative assessment and guide students to develop their argumentative skill.

Auto Deco Primer Valve är ett projekt som har resulterat i ett förenklat startsystem för tvåtaktsmotorer. Att starta en tvåtakts motor med dragsnöre är både tidskrävande och jobbigt, därför vill projektgruppen ge samhället en lösning på problemet. Genom ett befintligt koncept har syftet varit att fullborda detta system genom en ny innovativ lösning i form av en multifunktionel ventillösning.   Ventilen och dess ingående system är tänkt att ersätta två funktioner som återfinns på de flesta tvåtaktsmotorer idag: Dekompressionsventil och Chokereglage   Vår nya ventil gör att det tidigare manuella systemet automatiskt, och tar på så sätt bort de steg som måste utföras innan motorn startas.   Det nya systemet som förverkligas i ”Auto Deco Primer Valve” kommer att medföra många fördelar som beskrivs utförligare längre fram i rapporten.   Målet vid projektets slut har varit att ta fram en fungerande prototyp vilket projektgruppen har åstadkommit. Arbetet har inneburit en stor del av kreativt tänkande, för att kunna kombinera vetenskap om bland annat pneumatik med ett mekaniskt system.   För att bygga ett hållbart system som klarar marknadens tuffa krav och samtidigt inte är beroende av elektricitet så har stor del av arbetet bestått av att utveckla, beräkna, dimensionera, samt förenklat systemets olika delar och sedan modellera detta i Catia V5 R20.   Projektet har resulterat i en funktionsprototyp med fullständigt CAD-underlag som Husqvarna AB kommer att använda till att vidareutveckla systemet.   Med detta arbete vill vi ge samhället och framförallt skogsbranschen ett tillförlitligare hjälpmedel, genom en ny innovativ lösning, som gör att ett motorsystem för tvåtaktsmotorer blir mer driftsäkert, lättare att använda och snabbare att starta.

Denna studie har som syfte att undersöka hur pedagoger i förskolan uppfattar undervisningsbegreppet. Via våra frågeställningar vill vi vidare ta reda på hur pedagogerna uppfattar undervisningsbegreppet i förhållande till sitt uppdrag formulerat i läroplanen och hur de tillämpas i den pedagogiska verksamheten. Vi har valt att genomföra en kvalitativ forskning med en fenomenografisk ansats då den gör det möjligt för oss att ta del av en variation olika uppfattningar. Utifrån ett kvalitativt frågeformulär kommer vi att samla in svar i textform som vi sedan analyserar och tolkar för att kunna urskilja en variation i resultatet. Vårt forskningsämne kommer att placeras in i ett redan existerande forskningsfält och centralt för vårt valda ämne är begrepp som samspel och kommunikation och därför tar vi fäste i utvecklingspedagogiken och Vygotskijs sociokulturella perspektiv. De båda perspektiven beskriver olika aspekter av utveckling och lärande, vilka är centrala i diskussionen kring undervisningbegreppet. Resultatet visar att pedagogerna uppfattar undervisning som målstyrda processer där pedagoger och barn i samspel utvecklar ny kunskap. Vi kan dock urskilja en variation i det faktiska användandet av begreppet då en grupp pedagoger medvetet väljer att inte använda sig av eller tala om det. Vår slutsats är att det sker undervisning i förskolan trots att pedagoger väljer att inte ge uttryck och utrymme för begreppet.

Vid insjuknandet i diabetes typ 2 sker en förändring i patienters liv. En del av behandlingen vid sjukdomstillståndet är att förändra kost- och motionsvanor. Egenvården är en viktig del av de livsstilsförändringar som är aktuella. Patienterna kan genom egenvården bromsa sjukdomsutvecklingen och på så sätt bibehålla en god hälsa. Tidigare forskning har visat på svårigheter i genomförandet av livsstilsförändringar. Syftet med litteraturstudien är att undersöka hur livsstilsförändringar upplevs av patienter med diabetes typ 2. Litteraturstudien bygger på åtta vetenskapliga artiklar. Samtliga artiklar belyste upplevelsen av livsstilsförändringar vid diabetes typ 2. Data har analyserats genom Axelssons (2012) modell i skapandet av en ny helhet. Litteraturstudiens resultat presenteras i två huvudteman och sex subteman. De två huvudteman är Att ställas inför utmaningar och Att uppleva en positiv dimension. Att ställas inför utmaningar visade att livsstilsförändringarna kunde upplevas som krävande, utmanade och svåra av patienterna. Det visade även hur mötet med hälso- och sjukvården kunde upplevas som besvärligt men samtidigt stödjande. Att uppleva en positiv dimension visade hur patienterna upplevde att integreringen av livsstilsförändringar främjade hälsan och balansen i livet. Upplevelsen av livsstilsförändringar är personlig och unik för varje patient. Sjuksköterskan bör ha detta i åtanke i mötet med patienten där vårdrelationen blir central. En vårdande relation kan hjälpa patienten till att skapa varaktiga och långsiktiga förändringar som deras sjukdomstillstånd kräver.

The present master's dissertation had the objective to analyze the types of responses the programmes of work and income, its limits and possibilities as mechanisms for reintegration of unemployed in the market of work, in the city of São Paulo, between 2001 to 2006. The search started the idea that the answers are limited and palliatives front to the increase of the unemployment and the precarization of the market of work. The work was supported in bibliographical survey, of documents and empirical research with the beneficiaries of the programs, social workers and managers. The study showed that the social programs of work and income meet partially a share of the demands of work and income of a parcel of the poor population and do not guarantee the reintegration in the market of work. The types of answers were the granting of aid-money to smooth the difficulties of the population about the lack of work; responsibility of the person by their situation of unemployment, the spread of alternative forms of employment and generation of income through self - employment forms and associations of different modalities
A presente dissertação de mestrado teve o objetivo de analisar os tipos de respostas dos programas de trabalho e renda, seus limites e possibilidades como mecanismos de reinserção de desempregados no mercado de trabalho, na cidade de São Paulo, entre 2001 a 2006. A pesquisa partiu da idéia de que as respostas são limitadas e paliativas frente ao aumento do desemprego e à precarização do mercado de trabalho. O trabalho apoiou-se em levantamento bibliográfico, de documentos e pesquisa empírica junto a beneficiários dos programas, assistentes sociais e gestor. O estudo revelou que os programas sociais de trabalho e renda atendem parcialmente as demandas de trabalho e renda de uma parcela da população pobre e não garantem a reinserção no mercado de trabalho. Os tipos de respostas encontradas foram a concessão de um auxílio-monetário para suavizar as dificuldades da população em relação à falta de trabalho; responsabilização da pessoa por sua situação de desemprego; a propagação de formas alternativas de trabalho e geração de renda, através do auto-emprego e de formas associativas de distintas modalidades

Denna uppsats handlar om hur programmering som verktyg i matematisk problemlösning har implementerats sedan det infördes som obligatoriskt i flera av gymnasiets mattekurser hösten 2018. Syftet är att reda ut vilka programmeringsspråk och programbibliotek som används ute i klassrummen och hur det upplevs av elever och lärare med avseende på svårighetsgrad, nytta för matematiken och om det bidragit till ett ökat intresse för programmering i allmänhet hos eleverna. Även eventuella könsrelaterade skillnader i dessa frågor har undersökts, då en av de politiska intentionerna med införandet varit att en förhoppning att främja flickors it-intresse. Arbetet tar sitt teoretiska avstamp i en genomgång av den politiska bakgrunden till införandet, tidigare studier i ämnet och en kort historik om programmeringens roll i läroplanerna. Med hjälp av digitala enkäter har fallstudier företagits i två klasser från olika gymnasieskolor i Skåne, där elever och lärare fått ta ställning till antal påstående genom att gradera på en skala hur väl påståendena stämmer samt komplettera med eventuell textkommentar. Enkäterna var anonyma men utformade på ett sådant sätt att lärare och elever kunnat kopplas samman klassvis. Av resultatet har framkommit att många elever visserligen uppfattar programmeringen som svår och inte anser att den underlättar förståelsen för matematik. Men det framkom också att skillnaden var stor i dessa frågor och svaren tycks hänga samman med lärarens tidigare erfarenhet av programmering och i vilken omfattning programmeringen lärts ut. Intresset för programmering i allmänhet tycks inte ökat nämnvärt p.g.a. att det ingår i matematiken, men det låter sig heller inte entydigt sägas om någotdera könet var mer positivt eller negativt inställd till programmeringen. En något större andel tjejer än killar valde det allra mest negativa alternativet i enkätfrågorna, men klumpar man samman de mest negativa respektive de mest positiva alternativen på varsin halva om mitten, var tjejerna å andra sidan något överrepresenterade bland de positiva alternativen. Python verkar vara ett lämpligt programmeringsspråk att använda. Det är viktigt att tillse att lärare har tillräcklig kunskap i programmering och att omfattningen i utlärandet av programmering inte blir alltför ytlig, för att eleverna skall tillägna sig nyttan av det. Obligatorisk programmering i matematik kan potentiellt bidra till att fler för upp ögonen för ämnet och på sikt minska den sneda könsfördelningen bland yrkesprogrammerare.

Methicillinresistent Staphylococcus aureus (MRSA) är en multiresistent bakterie som är ett hälsoproblem över hela världen. Genom mutationer i bakterien skapas en resistens mot antibiotika. Faktorer som bidrar till den ökade spridningen och resistens av MRSA är bland annat dålig handhygien/hygien bland vårdpersonal på sjukhus, samt överanvändning av antibiotika. Personer som är bärare av MRSA riskerar då att inte kunna behandlas med antibiotika vid bakteriella infektioner, vilket kan medföra längre vårdtider eller i värsta fall hot mot hälsan och riskerar då att inte överleva dessa infektioner. Syfte: Att beskriva vårdprogram för MRSA i Sverige, Tyskland och Spanien. Metod: Metoden som använts är litteraturöversikt. Resultat: Vårdprogrammen för att minska spridningen av MRSA består samma riktlinjer i de olika länderna i Europa. Varför spridningen ser olika ut beror i stor utsträckning på vilka förutsättningar som finns i de olika länderna samt hur antibiotikakonsumtionen ser ut. Vissa länder har hög exponering av antibiotika inom djurhållningen, vilket ökar spridningen av MRSA. Konklusion: Trots stora skillnader i spridningen av MRSA ligger inte problemet i vårdprogrammen och dess riktlinjer för MRSA för länder i Europa. Vid jämförelse av länder med hög spridningen av MRSA respektive låg blev slutsatsen att det största problemet ligger i vilka förutsättningar vårdpersonalen har för att genomföra goda hygienrutiner samt brist eller bättre tillgång på kunskap och mer frekventa utbildningar kring MRSA och spridningen av resistenta bakterier.

This work presents itself as a result of the research: Women as the subject of crime: a study on the complex reality of the criminal inmates Dr. John Keys - Natal / RN, done with women incarcerated in the Women's Pavilion Complex Criminal Dr. John Keys. Aimed to investigate the key determinants that lead women to enter the institution to be subject of crime. To better understand the object of our study, we start to understand and analyze the social reality, economic and cultural these women, as well as seizure of their family relationships and emotional, within a gender perspective and consider the analysis of major crimes committed and their determinations. In our study, it appears from successive approximations and procedures theoretical and methodological quality and quantity, we were privileged to documentary research, observation and semi-structured, beyond the theoretical foundation on the subject - that the question of increase in recent years, women in the criminal occurs as a result of socioeconomic reality experienced by those. At the same time, the study has also believe that poverty and crime are not phenomena of cause and effect, however, it is undeniable that the large number of prisoners (as) are poor and live situation of denial of rights. The main focus of the research points to the socio-emotional relationships, both marital and family as the main determinant for inclusion of women in crime, breaking with the myth that the woman is "fragile sex." And, more, points out that the woman in the process of emancipation and achievement of public spaces to commit a crime seek equal to the male. Moreover, the research also denounced in a prison system collapsed, and totally abandoned by the public. That denies all rights provided to prisoners (as), both inside and outside the "walls". It is a system that criminalizes and no one wants to fulfill its role, which is the functional rehabilitation and resocialization of (the) inmates (those). It is hoped that this work could contribute to the unveiling of the reality of women in the criminal - no pretension of exhausting it - and can also contribute to further studies on the subject

Para compreendermos mais adequadamente o nosso objeto de estudo, partimos da compreens?o e an?lise da realidade social, econ?mica e cultural destas mulheres, assim como, da apreens?o de suas rela??es familiares e afetivas, dentro de uma perspectiva de g?nero, bem como consideramos a an?lise dos principais crimes praticados e suas determina??es.

Ao mesmo tempo, o estudo permitiu entender tamb?m que pobreza e criminalidade n?o s?o fen?menos de causa e efeito, por?m, ? ineg?vel que o grande n?mero de presidi?rios (as) s?o pobres e vivenciam situa??o de nega??o de direitos. O foco principal da pesquisa aponta as rela??es s?cio-afetivas, tanto conjugais como familiares como principais determinantes para inser??o das mulheres na criminalidade, rompendo com o mito de que a mulher ? sexo fr?gil . E, mais, aponta que a mulher em seu processo de emancipa??o e conquista dos espa?os p?blicos ao cometerem um crime procuram equiparar-se ao sexo masculino. Por outro lado, a pesquisa tamb?m nos denuncia um sistema penitenci?rio falido, e totalmente abandonado pelo poder p?blico. Que nega todos os direitos previstos aos presos (as), tanto dentro como fora dos muros . ? um sistema que criminaliza e nem se quer consegue cumprir o seu papel, funcional que ? a ressocializa??o e a reeduca??o das (os) presidi?rias (os).

Resumo:
In dieser Arbeit steht die Frage im Vordergrund, inwieweit eine besondere Orientierung sozialen und pädagogischen Handelns, die Orientierung an Face, im hochschulischen Raum Spanien als handlungsleitendes Konstrukt aufgezeigt werden kann und inwieweit dies mit den in chinesischsprachigen Kulturräumen verorteten Konzepten von Face vergleichbar ist. Face wird als transkulturelles, individuell und kollektiv bedeutsames Orientierungsmuster verstanden, dessen Kenntnis und handlungswirksame Umsetzung die Grundlage pädagogisch bedeutsamer Internationalisierungsstrategien stellen kann. Das Grundanliegen dieser Arbeit ist der Versuch, auch für einen europäischen Sprach- und Kulturraum Face als soziale Orientierung, speziell im pädagogischen Handlungsfeld Hochschule, aufzuzeigen und daraus Handlungsräume für die Gestaltung studienfördernder Lern- und Lehrkonstellationen bei internationalen Studierenden zu entwerfen. Die vorliegende qualitativ-ethnomethodologische Datenerhebung besteht aus einer Kombination mehrerer Erhebungsinstrumente, die im Rahmen von zwei aufeinander aufbauenden Studien in Spanien und Deutschland verwendet wurden. Studie 1 ist eine Teilnehmende Beobachtung im Forschungsfeld in Kombination mit der Critical Incident Technique, Studie 2 besteht aus leitfadengestützten ethnographischen und problemzentrierten Interviews. Zentrale Ergebnisse der Datenauswertung sind, dass Face als relationales Konstrukt im Bereich der Lehr-/Lernstilforschung von hoher Relevanz ist. Der Ausdruck El qué dirán kann als spanische Entsprechung für Face angesehen werden. Die in diesem Zusammenhang entwickelten Modelle – das Vínculo-Modell und das Enchufe-Modell – bieten eine kultursensible Darstellung von Face. Von diesen Ergebnissen ausgehend werden Implikationen für eine Face-sensible Lehre aufgezeigt und Anregungen für die Gestaltung studienfördernder Lern- und Lehrkonstellationen bei internationalen Studierenden gegeben.
This paper focuses on the question to what extent a special orientation of social and pedagogic action, the orientation towards Face, can be shown to be a presumed construct in higher education in Spain and to what extent this can be connected to the concepts of Face observed in Chinese-speaking cultural areas. Face is understood as a transcultural, individually and collectively significant orientation pattern, the knowledge and effective implementation of which can form the basis of pedagogically significant internationalisation strategies. The basic aim of this paper is to attempt to identify Face as a social orientation for a European language and cultural area as well, especially in the field of higher education as an area of pedagogic action, and to use this as a basis for designing study-enhancing learning and teaching constellations among international students. The qualitative ethnomethodological data collection used consists of a combination of several survey instruments used in two consecutive studies in Spain and Germany. Study 1 is a participant observation in the research field in combination with the Critical Incident Technique; Study 2 consists of guideline-based ethnographic and problem-oriented interviews. Central results of the data evaluation are that Face is of high relevance as a relational construct in the field of teaching/learning style research. The expression El qué dirán can be regarded as the Spanish equivalent of Face. The models developed in this context – the Vínculo model and the Enchufe model - were taken from the data and offer a culturally sensitive representation of Face; they can be understood as a culture-specific supplement to the social orientation triangle (Henze 2011) for understanding social interaction. Based on these results, implications for face-sensitive teaching are identified and suggestions for the design of study-enhancing learning and teaching constellations for international students are made.

Cette thèse s'attache à l'étude économique sociale et culturelle de la noblesse de quatre élections rurales du centre de la Normandie durant le dernier siècle de l'Ancien Régime (1700-1790). En exploitant informatiquement de nombreuses sources sérielles, enrichies par l'analyse de multiples dossiers familiaux, il a été dégagé les grandes structures mais aussi les évolutions d'une noblesse vivant en milieu rural. Après avoir examiné les fondements et le poids social de ce groupe nobiliaire (nombre, ancienneté, puissance seigneuriale et foncière), une analyse des activités et revenus de la noblesse aboutit à sa hiérarchisation selon son niveau de fortune. La société noble est ensuite appréhendée par le biais de sa culture matérielle et intellectuelle, afin d'éclaircir les conditions de vie quotidienne, le cadre dans lequel le foyer peut batir sa sociabilité, mais aussi s'interroger sur la transmission des valeurs par l'éducation et sur les conditions de la construction d'une culture personnelle. Enfin, cette thèse examine la dynamique nobiliaire du XVIIIIe siècle et la pérennité du groupe, tant naturelle que sociale, dans cet espace rural de Normandie. Une question se fait jour : la noblesse arrive-t-elle à préserver, tout au long du XVIIIe siècle, le contrôle des différents pouvoirs locaux?

Ziel der Dissertation ist es, eine umfassende Analyse der kambodschanisch-thailändischen diplomatischen Beziehungen von 1950 bis 2014 zu liefern. Die Arbeit geht über einen rein historischen Bericht hinaus, da sie darauf abzielt, die Wechselhaftigkeit der kambodschanisch-thailändischen Beziehungen zu erklären. Als Grundlage dient hierzu ein Ansatz sozialen Konflikts, der Staaten nicht als homogene Akteure ansieht, sondern vielmehr als eine Konfiguration konfligierender Kräfte, die ihre außenpolitischen Ziele im Einklang mit ihrer eigenen Ideologie, ihren Interessen und ihren Strategien verfolgen. Daher postuliert die Arbeit, dass die kambodschanisch-thailändischen Beziehungen nicht als Produkt einheitlicher Staaten angesehen werden sollten, die entweder miteinander kooperieren oder sich voneinander abschotten, sondern als Matrix sich überlappender Beziehungen zwischen gesellschaftlichen und politischen Gruppen beider Staaten, die konkurrierende Ideologien und/oder Interessen zur Förderung ihrer innenpolitischen Machtposition beherbergen. Das Projekt bringt zwei mit einer verknüpfte Argumente hervor. Erstens, kambodschanisch-thailändische Beziehungen sind wahrscheinlich dann kooperativ angelegt, wenn es sich bei beiden Machthabern um zivil-demokratisch gewählte Regierungen mit ähnlichen Ideologien, ökonomischen Interessen und Sicherheitsbedenken handelt. Umgekehrt verschlechtern sich die Beziehungen, wenn diese Faktoren nicht reziprok sind. Dies ist besonders dann der Fall, wenn eine der beiden Regierungen mehr mit der Opposition der anderen gemein hat. Zweitens, auch wenn antagonistische Nationalismen auf beiden Seiten bestehen, handelt es sich keinesfalls um eine Determinante, die die Außenpolitik beider Seiten festlegt. Die Arbeit argumentiert, dass Nationalismen nur dann aufgerufen werden, wenn zumindest eine der beiden Regierungen ihre Legitimität in der Heimat stärken muss und die andere Regierung nicht dieselbe Ideologie und strategischen Interessen teilt.
This dissertation aims to provide a comprehensive analysis of Cambodia-Thailand diplomatic relations over the past six decades, specifically from 1950 to 2014. In addition to empirical discussion, it seeks to explain why Cambodian-Thai relationships have fluctuated and what primary factors caused the shifts during the period discussed. In doing so, it employs the “social conflict” analysis, which views states not as unitary actors, but within which is comprised of different societal forces competing with one another and pursues foreign policies in accordance with their own ideology, interest, and strategy. As such, it is postulated that Cambodia-Thailand diplomatic relations should not be seen simply as relations between two unitary states cooperating with or securitizing against one another, but rather as a matrix of intertwining relationships between various social and political groups in both states harboring competing ideologies and/or interests to advance their power positions at home. Two inter-related arguments are therefore put forward in this research. Firstly, Cambodian-Thai relations are likely to be cooperative when both governments in power are civilian-democratically elected regimes and share similar ideologies, mutual economic interests, as well as security outlooks. Conversely, relations between them tend to deteriorate when these factors are not reciprocal. This is particularly true when one government has more in common with the dissidents of the government of the other side. Secondly, though antagonistic nationalism does exist between Cambodia and Thailand, it is not a determinant of the two nations’ foreign relations. This research argues that nationalism and historical animosity are invoked only if at least the government on one side needs to bolster its own legitimacy at home, and the government on the other side does not share a similar ideology or strategic interests with its own – the second aspect being the more important factor here.

Höhere Spin Theorien haben in den letzten Jahren große Aufmerksamkeit gefunden. Ein Grund dafür ist, dass diese Theorien dual zu besonders einfachen konformen Feldtheorien sind. Die einzigen bekannten wechselwirkenden höheren Spin Theorien wurden von Vasiliev in einem sehr ungewöhnlichen Formalismus und mit unendlich vielen Hilfsfeldern konstruiert. Die vorliegende Arbeit extrahiert die Physik, die durch diese Gleichungen beschrieben wird. Wir untersuchen im Detail die Wechselwirkungen, das Spektrum sowie die Lokalitätseigenschaften der Vasiliev Theorie. Diese Arbeit ist die erste systematische Untersuchung der Vasiliev Theorie auf wechselwirkender Ebene (nur ausgedrückt durch physikalische Felder).
Higher-spin theories have received significant attention over the last years. This is because they arise as the bulk duals of comparatively tractable conformal field theories. The only known interacting higher-spin theories were constructed by Vasiliev and are formulated in a highly non-standard way in terms of an infinite number of auxiliary fields. This thesis extracts physics out of Vasiliev theory. We study in detail its interactions, spectrum and locality properties. We consider both the three- and four-dimensional case. Our work represents the first systematic study of Vasiliev theory at the interacting level (in terms of physical fields only).

Die vorliegende Arbeit beschäftigt sich mit der Synthese von Pincer-Ligandenvor-läufern mit fluorierten Alkylketten –(CH2)2Rf6 (Rf6 = C6F13) an Sauerstoff- bzw. Phosphorhaftatomen. Darüber hinaus stehen die Bildung hochfluorierter Lithium-, Palladium-, Ruthenium- sowie Aluminium-Pincer-Komplexe und die Reaktivitäts-studien für diese neuartigen Komplexe im Fokus. Für vergleichende Untersuchungen war ebenso die Synthese der analogen, nicht fluorierten Verbindungen von Interesse. Eine Mischung aus in situ hergestelltem (NC5H3)-1,3-(CH2P((CH2)2(CF2)5CF3)2)2 (13) und [Ru(2Me-C3H4)2(cod)] kann die Dehydrogenierung von Cyclooctan bei vergleichsweise niedrigen Temperaturen von 80 °C katalysieren. Interessant ist die je nach Lösungsmittel unterschiedliche Produktbildung. Die Lithium- und Aluminiumkomplexe [Li(C6H3-2,6-(CH2O(CH2)2(CF2)5CF3)2)] (21), [Li(C6H3 2,6 (CH2OCH3)2)] (22), [Al((C6H3)-2,6-(CH2O(CH2)2(CF2)5CF3)2)(CH3)2] (28), [Al((C6H3)-2,6-(CH2OCH3)2)I2] (29), [Al((C6H3)-2,6-(CH2O(CH2)2(CF2)5CF3)2)I2] (31) wurden erfolgreich synthetisiert und charakterisiert. Mittels [Al((C6H3)-2,6-(CH2O(CH2)2(CF2)5CF3)2)I2] (31) konnten diverse aromatische Verbindungen wie Benzol, Toluol oder Pentafluorbenzol dehydrogenierend gekuppelt werden. Weiterhin wurden die Palladiumkomplexe [Pd(Cl)((C6H3)-2,6-(CH2O(CH2)2(CF2)5CF3)2)] (34) und [Pd(NCCH3)((C6H3)-2,6-(CH2O(CH2)2(CF2)5CF3)2)][PF6] (36), [Pd(Cl)((C6H3)-2,6-(CH2OCH3)2] (37) und [Pd(NCCH3)((C6H3)-2,6-(CH2OCH3)2][PF6] (38) hergestellt und charakterisiert.
The current thesis is concerned with the syntheses of pincer ligand precursors with fluorinated alkyl chains –(CH2)2Rf6 (Rf6 = C6F13), the so called „ponytails“, at oxygen or phosphorous donor atoms. Furthermore, this work focuses on the formation of highly fluorinated lithium, palladium, ruthenium or alumina pincer complexes and considering reactivity studies of these novel compounds. For comparative investigations the syntheses of the analog non-fluorinated compounds was of great interest. A mixture of in situ synthesized (NC5H3)-1,3-(CH2P((CH2)2(CF2)5CF3)2)2 (13) and [Ru(2Me-C3H4)2(cod)] catalyses the dehydrogenation of cyclooctane at relatively low temperatures of 80 °C. Depending on the used solvent cyclooctene or cyclooctatriene can be received as the single product, respectively. The lithium and alumina complexes [Li(C6H3-2,6-(CH2O(CH2)2(CF2)5CF3)2)] (21), [Li(C6H3 2,6 (CH2OCH3)2)] (22), [Al((C6H3)-2,6-(CH2O(CH2)2(CF2)5CF3)2)(CH3)2] (28), [Al((C6H3)-2,6-(CH2OCH3)2)I2] (29), and [Al((C6H3)-2,6-(CH2O(CH2)2(CF2)5CF3)2)I2] (31) were synthesized and characterized succesfully. With the complex [Al((C6H3)-2,6-(CH2O(CH2)2(CF2)5CF3)2)I2] (31) a diversity of aromatic compounds like benzene, toluene or pentafluorobenzene can be coupled after dehydrogenation. Moreover, the palladium complexes [Pd(Cl)((C6H3)-2,6-(CH2O(CH2)2(CF2)5CF3)2)] (34), [Pd(NCCH3)((C6H3)-2,6-(CH2O(CH2)2(CF2)5CF3)2)][PF6] (36), [Pd(Cl)((C6H3)-2,6-(CH2OCH3)2] (37) and [Pd(NCCH3)((C6H3)-2,6-(CH2OCH3)2][PF6] (38) were synthesized and characterized.

Das Forschungsfeld der Synchrotronstrahlungsquellen hat sich in den letzen Jahren entscheidend weiterentwickelt. Alle Zukunftsideen, unabhängig von ihrer Komplexität, haben dennoch eines gemeinsam: die Erzeugung kurzer Pulse. Die Naturwissenschaften haben die Spitzenbrillanz, die mit Hilfe kürzester Pulse produziert werden kann, als neues Schlüsselwerkzeug entdeckt. Die Nutzergemeinschaft verlangt nicht mehr nur ein statisches Bild, sondern vielmehr eine Reihe von bewegten Aufnahmen atomarer Substrukturen und den dazugehöringen Prozessen. Existierende dritte Generation Synchrotronstrahlungsquellen werden an die neuen Herausforderungen angepasst: Verbesserungen an der Magnet-Optik sowie der Einbau modernster Beschleunigertechnologie ermöglichen die Erzeugung kürzester Pulse mit höchster Brillanz für zeitaufgelöste Experimente. Ein möglicher Kandidat für die Lichtquelle der nächsten Generation ist ein Linear-Beschleuniger mit Energierückgewinnung. Durch die Verwendung langer Beschleunigungsstrukturen kann es, selbst bei hohen Energien, nicht zur Ausbildung des Emittanzgleichgewichts wie in Speicherringen kommen. Durch die Verwendung Impulsabhängiger-Umlaufbahnen und der Rückgewinnung der Strahlenergie ist es mit `Energy Recovery Linac'' (ERL)-basierten Quellen energieeffizient möglich, hochenergetische Elektronen-Pulse im Femtosekundenbereich zu erzeugen. Die longitudinale Elekronstrahldynamik solcher ERLs ist eines der Hauptthemen dieser Arbeit. Umfangreiche Simulationen über die gesamte Maschine wurden im Rahmen der `Femto-Science Factory'' Lichtquellen Studie durchgeführt. Die Begrenzungen des Kurzpulsmodus Betriebes wurden untersucht und mit den Erwartungen verglichen. Besondere Aufmerksamkeit lag dabei auf den 6D Elektronenstrahleigenschaften, insbesondere auf der Vermeidung von Strahlaufweitungen, die mit der Erzeugung von Ultra-Kurzpulsen einhergehen können.
Synchrotron light sources are entering a new era. No matter how elaborate, all the next generation proposals share a common necessity; the production of ultra-short electron bunches. There is an evolution in the field of science under investigation using the high peak brilliance generated from such bunches. The user community is demanding not just pictures but videos of atomic substructures and the processes that define them. Existing 3rd generation facilities are modifying their magnetic lattices and upgrading the acceleration schemes in order to keep up with this trend of generating short pulses with ultimate brilliance for time resolved experiments. A possible candidate for the next generation light source is one based on ERL technology. Using long linacs to accelerate to high energies overcomes the present limitation of emittance equilibrium in storage rings. By implementing independent arcs for acceleration and deceleration while recuperating the beams energy, ERL based sources are theoretically capable of efficiently producing high energy femtosecond long bunch lengths. The study of the longitudinal motion of the beam through single pass magnetic optic in combination with linacs is the main topic of this thesis. Dedicated start-to-end simulations in the framework of the Femto-Science Factory large scale light source are undertaken. The expectations and restrictions on the short pulse mode (SPM) operation are comprehensively examined in this work. Particular attention is given to the 6D electron beam properties and with it the beam degradation caused by the production of ultra-short bunches.

Resumo:
In dieser Arbeit schlage ich eine phänomenalistische Interpretation von Kants Idealismus vor, die sich jedoch in einigen Punkten von Standard-phänomenalistischen Interpretationen unterscheidet. Erscheinungen sind in meiner Lesart der Inhalt von Vorstellungen, aber nicht das eigentliche Objekt der Erkenntnis. Denn Erscheinungen sind von den erscheinenden Objekten verschieden. Diese sind vielmehr die Dinge an sich, welche wir zum transzendentalen Gegenstand der Erkenntnis machen. Allerdings erkennen wir sie lediglich, wie sie erscheinen, und nicht, wie sie sind. Somit bleibt die Unerkennbarkeit der Dinge, wie sie an sich sind, gewahrt. Im Verlauf meiner Argumentation diskutiere ich zahlreiche Aspekte von Kants Philosophie. Darunter sind die Unterscheidung zwischen Erscheinungen und Dingen an sich, Kants Verhältnis zur Cartesischen Epistemologie, die Widerlegung des Idealismus, sowie nicht zuletzt seine Theorie der Synthesis zu nennen. Mein Ziel ist dabei nicht nur zu zeigen, dass Kant ein Phänomenalist ist, sondern auch die Art seines Phänomenalismus zu charakterisieren.
This publication defends a phenomenalist interpretation of Kant’s idealism, which, however, deviates from usual phenomenalist interpretations in several respects. According to my reading, appearances are the content of representations, but not the true object of cognition. The object to which our cognition refers is rather the thing itself as the transcendental object. Nonetheless, we only cognize them as they appear and not as they are in themselves. Thus the unknowability of things as they are in themselves is retained. In the course of my presentation, I discuss a number of aspects of Kant’s philosophy, among which are the distinction between appearances and things in themselves, Kant’s relationship to Cartesian epistemology, the refutation of idealism, and not least his theory of synthesis. My aim is not only to show that Kant is a phenomenalist, but also to characterize the kind of his phenomenalism.

In der Dissertation wurden Effekte der zuwanderungsbezogenen Klassenzusammensetzung auf verschiedene Leistungsmaße und psychosoziale Schülermerkmale im Rahmen von drei Zeitschriftenbeiträgen untersucht. In Teilstudie eins wurden Effekte der sozialen und zuwanderungsbezogenen Zusammensetzung auf das Leseverständnis im Verlauf der neunten Klasse und deren Vermittlung durch Merkmale der Unterrichtsqualität analysiert. Der Klassenanteil von Heranwachsenden mit Zuwanderungshintergrund war unter Kontrolle des mittleren sozioökonomischen Status nicht mit der Leseleistung assoziiert. Es zeigten sich Hinweise einer partiellen Vermittlung des Effekts sozialer Zusammensetzung durch das Ausmaß herausfordernden Sprachunterrichts. Teilstudie zwei beschäftigte sich mit Effekten der Zusammensetzung auf die Lernmotivation im Verlauf der neunten Klasse und deren Vermittlung durch das Ausmaß schülerorientierten Unterrichtsklimas. Heranwachsende mit Zuwanderungshintergrund berichteten höhere Motivation, wenn sie Klassen mit einem höheren Anteil von Heranwachsenden mit Zuwanderungshintergrund besuchten. Es zeigten sich keine vermittelten Effekte durch Merkmale des Unterrichtsklimas. In Teilstudie drei wurden der Anteil von Kindern mit Zuwanderungshintergrund und Maße zuwanderungsbezogener Heterogenität in ihrer Assoziation mit Mathematik- und Leseleistung sowie dem Verbundenheitsgefühl mit Peers von Kindern der vierten Klasse verglichen. Es bestanden stärkere negative Effekte des Klassenanteils im Vergleich zu Heterogenitätsmaßen. Bei simultaner Berücksichtigung von Klassenanteil und Heterogenitätsmaßen waren Heterogenitätseffekte größtenteils nicht mehr signifikant. Es zeigten sich jedoch leicht positive Heterogenitätseffekte auf die Mathematikleistung. Es bestanden keine Effektunterschiede zwischen Heterogenitätsmaßen. Die Befunde verweisen auf die Bedeutung der Schulklasse für die akademische Entwicklung sowie für die Erklärung zuwanderungsbezogener Disparitäten im Bildungssystem.
The thesis at hand explored effects of the language-related and ethnic makeup of classrooms on several achievement outcomes as well as psychosocial outcomes in three research articles. The first article investigated effects of socioeconomic and language minority classroom composition on ninth graders’ reading achievement across two measurement points and explored the mediating role of instructional quality. The proportion of minority students had no effect on achievement after controlling for the socioeconomic composition. The results suggest that the effect of the socioeconomic composition on achievement may be mediated partially by the teacher’s focus on language during instruction. The second article focused on effects of the proportion of language minority students on the development of ninth graders’ motivation and the mediating role of a student-oriented climate. The analyses revealed that minority students were increasingly motivated in classrooms with a higher proportion of minority students. The compositional effect was not mediated by the instructional climate. The third article explored various measures of the ethnic makeup of classrooms and their relationship with student outcomes. The proportion of minority students and measures of diversity were compared in their prediction of fourth graders’ achievement in math and reading as well as the feeling of belonging with one’s peers. The proportion of minority students showed stronger negative effects on student outcomes than the diversity measures. Including diversity measures and the proportion of minority students, the diversity effects mostly lost their significance. However, students showed slightly higher levels of math achievement in more diverse classrooms. The various measures of diversity led to similar results. The findings add to the evidence indicating that the classroom learning environment affects students’ academic development and contributes to ethnic disparities in the education system.

Folienmanagement ist von wirtschaftlicher Bedeutung im Freiland-Gemüsebau im Frühjahr. Aber die Prognose des optimalen Zeitpunktes der Abnahme von Plastik-Abdeckungen vom Bestand ist mit den bereits verfügbaren Mitteln zu ungenau, um die heutigen Anforderungen an die Produktionssicherheit zu erfüllen. Der bislang verwendete empirische Ansatz benötigt aktuelle Referenzmessungen unter den Abdeckungen, welche kostspielig sind. Das Ziel dieser Arbeit war es, die Grundlagen eines mechanistischeren Modellansatzes zu entwickeln, welcher auf dem physikalischen und biologischen Verständnis von Energiehaushalt, Pflanzenwachstum und den Prozessen der Qualitätsentwicklung unter den Abdeckungen beruht, um die zukünftige Produktionssicherheit zu verbessern. Entsprechende Feldversuche wurden durchgeführt, um Daten zum Pflanzenwachstum und Mikroklima unter und über der Abdeckung zu erhalten und neue sowie etablierte Untermodelle zu parametrisieren. Weiterhin wurden Laborversuche zum Verständnis z.B. der optischen Eigenschaften der Abdeckungen, Blätter und des Bodens ausgeführt. Außerdem wurde eine neue Methode zur Bestimmung des Blattflächenindex bei Kopfsalat und Kohlrabi geprüft und für die effiziente Erhebung der Pflanzendaten etabliert (Sandmann et al. 2013). Im Ergebnis können nun verschiedene Prozesse der Gemüseproduktion unter Abdeckungen besser verstanden und mit hinreichender Genauigkeit mathematisch beschrieben werden, z.B. Strahlungshaushalt (Graefe & Sandmann 2014) und Blattflächenwachstum. Die meisten Ziele der Arbeit wurden erreicht. Weitere Arbeit ist vor allem notwendig für die Modellierung der Lufttemperatur unter der Abdeckung und die Entwicklung eines mechanistischen Ansatzes zur Beschreibung der Pflanzenqualität. Hier konnte die Pflanzenqualität wegen der subjektiv beeinflussten Daten nur über einen empirischen Ansatz modelliert werden. Die übliche Erfassung der Pflanzenqualität sollte überdacht werden, um zukünftig möglichst objektive Werte zu erhalten.
Plastic film management is economically of importance for vegetable growing in the field in early spring, but the prediction of the best moment of removal of plastics from the crops is currently too imprecise to fulfill contemporary requirements in production safety. The broadly used approach for prediction is of empirical nature and is depending on current reference data from below covers, which are expensive to gather. The aim of this thesis was to develop the scientific foundations for a more mechanistic model approach, based on the physical and biological understanding of the energy balance, plant growth and plant quality formation process below plastic covers in order to increase future production safety. Field trials at three sites, with two species and several cover materials and removal strategies were carried out to gain data from plants and microclimate beneath and above covers for parameterization of new and established submodels. Additionally, laboratory experiments were performed to understand e.g. the optical properties of plastics, leaves and soil. Furthermore, a new method for determining leaf area index in lettuce and kohlrabi was adopted and established for a more efficient plant data collection (Sandmann et al. 2013). As a result, several processes of vegetable production using plastic covers are now better understood and can be described mathematically and sufficiently precise, e.g. the short wave radiation budget (Graefe & Sandmann 2014) and leaf area growth. Most, but not all aims of the thesis could be achieved. Further work will be necessary according to modeling of air temperature below the covers, leaf gas exchange and the development of a mechanistic approach for plant quality formation. Here, plant quality could only be modelled via an empirical approach, due to subjectively influenced data. Common plant quality data acquisition should be reconsidered to yield as much as possible objective values in the future.

Ein nicht-invasiver Atemtest zur Lungenkrebsdetektion setzt Kenntnis über lungenkrebsspezifische Substanzen voraus. Die Identifizierung von Lungenkrebsbiomarkern in der Atemluft war das Ziel dieser Arbeit. Leichtflüchtige organische Substanzen (VOC) wurden als Zielkomponenten ausgewählt. Für die VOC-Analytik wurde eine SPME-GC-MS-Methode entwickelt und sowohl auf Modellsysteme als auch auf Realproben angewendet. Drei Lungenadenokarzinomzelllinien wurden in-vitro untersucht. Die VOC-Analyse wurde mit drei verschiedenen Probenahmestrategien durchgeführt und es war ein deutlicher Hintergrundeinfluss der eingesetzten Einwegzellkulturflaschen auf das analysierte VOC-Profil feststellbar. Trotzdem konnten signifikante Unterschiede zwischen Tumorzellen und zellfreien Nährmedien beobachtet werden: 1-Propanol wurde von den Zellen produziert, während der Gehalt einiger Aldehyde sank. Die eingeschränkte Ähnlichkeit des gewählten Zellkulturmodells mit realen Atemluftproben bedingt eine geringe Eignung dieser Ergebnisse für die Biomarkerableitung. Ein Gasmodell auf Basis angefeuchteter, synthetischer Luft wurde als Grundlage für die qualitätsgesicherte, quantitative VOC-Analyse der realen Atemluftproben konzipiert. Diese Modellluft wurde mit 24 Zielsubstanzen (Alkane, Aromaten, sauerstoffhaltige Spezies) sowie 3 Matrix-VOC mit starker Dominanz in den Atemluftproben (Isopren, Aceton, 2-Propanol) angereichert. In Kooperation mit zwei Berliner Kliniken wurden 37 Atemluftproben von Lungenkrebspatienten und 23 Proben von Gesunden gesammelt. Die Anwendung von 1-Butanol als univariater Marker erlaubt eine Erkennung von Lungenkrebs mit einer Sensitivität von 92% und Spezifität von 78%. Durch lineare Diskriminanzanalyse konnte ein Set aus 4 VOC (1-Butanol, 2-Butanon, 2-Pentanon, n-Hexanal) ermittelt werden, welches ebenfalls eine Sensitivität von 92% und mit 87% eine höhere Spezifität aufwies. Gegebenenfalls handelt es sich bei diesen Substanzen jedoch nur um allgemeine Krankheitsmarker.
A non-invasive breath test for lung cancer detection would be favorable but knowledge on lung cancer specific substances is required. This work aims at the identification of potential lung cancer biomarkers in breath. Volatile organic compounds (VOC) were chosen as targets and a SPME-GC-MS method was developed to analyze the VOC profiles of model systems and real samples. Three lung adenocarcinoma cell lines were investigated in-vitro. The VOC analysis, carried out with 3 different sampling strategies, was influenced by the VOC background of the used disposable culture vessels. Changes in the VOC profiles of cell lines compared to cell-free culture media were obvious: 1-propanol was released by the tumor cells whereas the content of some aldehydes was diminished. The similarity of this model system with real breath samples of lung cancer patients was seen to be insignificant. Consequently, these cell cultures were not suitable for biomarker identification. A gaseous model consisting of humidified synthetic air was developed. It was fortified with 24 target VOC (alkanes, aromatics and oxygenated species) as well as 3 matrix compounds (isoprene, acetone and 2-propanol) dominating patients’ VOC profiles in breath. This model was used for the quality assured quantitative VOC analysis in real breath samples. In cooperation with two hospitals 37 single mixed expiratory breath samples from lung cancer patients and 23 from healthy controls were collected. Applying 1-butanol as an univariate biomarker patients and controls were discriminated with a sensitivity of 92% and a specificity of 78%. Linear discriminant analysis displayed a set of 4 VOC (1-butanol, 2-butanone, 2-pentanone, n-hexanal) with similar sensitivity but higher specificity of 87%. However, these potential biomarkers might rather be a consequence of illness in general.

Intentionale Kontrolle ist ein fundamentaler Aspekt menschlichen Verhaltens. Jedoch gibt es bei der neuronalen Basis solcher Kontrollprozesse noch immer viele offene Fragen. Bis heute bleibt beispielsweise umstritten wie das frontoparietale Intentions-Netzwerk organisiert ist. Weiterhin üben motivationale Prozesse einen großen Einfluss auf intentionale Kontrollprozesse aus. In früheren Studien wurden motivationale und intentionale Kontrollprozesse jedoch oft als unabhängige Funktionen verstanden und untersucht. Diese Dissertation untersucht die neuronalen Grundlagen intentionaler Kontrolle, vor allem auf den Einfluss zweier motivationaler Variablen (Aufgabenschwierigkeit, monetäre Belohnungen) und die funktionelle Organisation des Kontrollnetzwerkes fokussierend. Experiment 1 untersuchte Effekte motivationaler Prozesse auf volitionales Verhalten sowie die neuronale Grundlage dieser Effekte. Experiment 2 untersuchte welche Hirnregionen Verhalten mit seinen Konsequenzen assoziiert. Dies ist eine zentrale Funktion, möchte man die positiven Konsequenzen eigenen Verhaltens maximieren. Experiment 3 untersuchte direkt die Repräsentationen frei gewählter und extern determinierter Intentionen und somit auch die funktionale Architektur des intentionalen Kontrollnetzwerkes. Die Ergebnisse aller drei Studien betonen die Wichtigkeit des anterioren zingulären Kortex, dorsomedialen Präfrontalkortex und des parietalen Kortex für die Vermittlung motivationaler Effekte auf intentionale Kontrolle. Weiterhin deuten die Ergebnisse darauf hin, dass das frontoparietale Kontrollnetzwerk sowohl für die Kontrolle frei gewählten als auch extern determinierten Verhaltens wichtig ist. Diese Ergebnisse stellen einen wichtigen Beitrag für aktuelle Debatten über die neuronale Grundlage intentionalen Verhaltens dar, und erweitern aktuelle Theorien über motivationale und intentionale Kontrolle.
Freely choosing one’s own course of action is a fundamental aspect of human behavior. Yet, despite its importance, there remain many open questions about the neural basis underlying intentional control of action. On the one hand, the functional organization of the fronto-parietal brain network associated with intentional control remains a debated topic. On the other hand, motivational processes evidently affect intentional control, as we often choose actions which promise desirable outcomes. Despite this, previous research largely treated intentional and motivational control as two independent functions. This thesis aims at shedding light on the neural basis of intentional control, focusing on the effects of two motivational variables on intentional control processes (effort, monetary rewards), as well as the functional organization of the intentional control network. Experiment 1 investigated the effect of motivational processes on voluntary behavior and its neural basis. Experiment 2 assessed which brain regions associate behaviors with their outcomes, an important piece of information for choosing actions which lead the most desirable outcomes. Experiment 3 directly contrasted the representations of freely chosen and externally cued intentions, in this way investigating the functional organization of the intentional control network. Overall, results from those three experiments highlight the role of the dorsal anterior cingulate, dorso-medial prefrontal, and parietal cortex in mediating motivational effects on intentional control. They further suggest that the fronto-parietal intentional control network likely has a role in both controlling behavior that is freely chosen and externally cued. These results inform debates on the neural basis of intentional control and extend some recent theories of motivational and intentional control functions. They provide a promising starting point for a systematic investigation of the neural basis of intentional control.

Im Mittelpunkt der Arbeit steht das soziale Phänomen Volunteering in der sozialen Institution Public Library mit konkretem Bezug auf die Gegebenheiten in den USA. Die Behandlung des Themas erfolgt auf der Basis von Quellen sowie den Ergebnissen einer qualitativen Untersuchung. Zunächst werden die historischen Hintergründe von Volunteering und Philanthropie in den Vereinigten Staaten sowie die Entwicklungsgeschichte der US Public Libraries beschrieben und diskutiert. Zwischen beiden Phänomenen werden Zusammenhänge aufgezeigt. In diesem Kontext wird auch die Rolle Andrew Carnegies herausgearbeitet. Des Weiteren werden der gegenwärtige Stand der Freiwilligenforschung mit den Schwerpunkten Motivation und Volunteer-Management sowie das Wirken von Volunteers in US Public Libraries unter politischen, soziologischen und administrativen Gesichtspunkten erörtert. In Auswertung der qualitativen Untersuchung, die eine Kombination aus Feldforschung und problemzentrierten Interviews – durchgeführt in insgesamt 31 Public Libraries in elf US-Bundesstaaten – darstellt, werden eine Reihe von Erkenntnissen gewonnen, die unter anderem Rückschlüsse auf die Bibliotheksspezifik von Volunteering – insbesondere in Hinsicht auf die Motivation zur Freiwilligenarbeit sowie dem Volunteer-Management – ermöglichen.
This thesis describes the social phenomenon of volunteering in the public library as a social institution, focused on the situation in the United States of America. The paper is based on a literature review and on findings of a qualitative study. After discussing the history of volunteering, philanthropy, the American public library, and Andrew Carnegie’s role, there will be a review on research on volunteerism. Thereby, the focus is laid upon aspects of volunteer motivation as well as volunteer management in the US in general and particular in libraries. Furthermore, a compilation and interpretation of library volunteer coordinators’ materials, manuals, and reports will be presented. The results of the qualitative study which is based on a combination of field research and problem-centered interviews – held in 31 public libraries in eleven US states – will be discussed in detail. Among others, the results lead to the conclusion that – especially concerning several motivational and management aspects – public library volunteering is quite specific in comparison to volunteer work in other facilities and institutions.

In questo lavoro di tesi viene eseguita un'analisi accurata in banda radio e nei raggi X dell'ammasso di galassie Abell 2495. Questo oggetto è stato selezionato tra gli ammassi con più alto flusso X e luminosità Halpha; queste sembrano infatti essere caratteristiche peculiari degli ammassi cosiddetti cool-core. In aggiunta, questi dati sono stati confrontati con quelli relativi all'emissione Halpha presentati in letteratura. Dal confronto dell'emissione X e radio sono state ricavate le proprietà principali dell'ammasso e della radiosorgente posta al centro della galassia (BCG). Sono stati individuati due offset, uno tra l'emissione radio e il picco X e uno tra quest'ultimo e il picco Halpha, che possono indicare che il raffreddamento non stia attualmente depositando gas sulla BCG. Si è inoltre investigata la presenza di possibili cavità dell'ICM, che si pensa siano generate dall'attività dell'AGN, valutando grazie ad esse l'impatto che gli offset di cui sopra possono avere nei processi di raffreddamento e feedback che caratterizzano l'ammasso.

L’insufficienza renale è una condizione che colpisce milioni di persone al mondo. Gli individui affetti da patologie renali sono purtroppo soggetti ad un progressivo ed inesorabile peggioramento della qualità della vita. Al giorno d’oggi è possibile garantire una vita normale ai pazienti, grazie a un procedimento chiamato dialisi. Esistono diverse tecniche dialitiche ma tutte si propongono lo stesso obiettivo: sostituire la funzione renale nei soggetti in cui questa sia irrimediabilmente compromessa. Le tecniche dialitiche si sono evolute nel corso degli anni e tra le innovazioni di maggior importanza si evidenzia l’impiego di nuovi materiali per la realizzazione della membrana di dialisi. In questo studio di tesi si è analizzato lo stato dell’arte dei materiali impiegati per la produzione di membrane attualmente in uso su macchine di dialisi, studiando i fenomeni di trasporto della materia attraverso una membrana semipermeabile e i parametri che la caratterizzano. In particolare si è rivolta l’attenzione a come questi materiali possano garantire una maggior efficienza nella rimozione delle tossine e nella riduzione della mortalità associata al contatto della membrana con il sangue, permettendo di migliorare la qualità della terapia dialitica mediante la possibilità di realizzare fibre con diverse caratteristiche ottenute agendo sui parametri fondamentali delle membrane come cut off, coefficienti di ultrafiltrazione e di sieving e a loro volta questi parametri uniti alla possibilità di disporre le fibre all’interno dei filtri secondo diverse geometrie, in base alle esigenze, permettono di adattare la terapia di dialisi alle necessità di ciascun paziente.

Questo elaborato di tesi si inserisce nel contesto della ricerca di stelle Evolved Blue Straggler Stars (E-BSS) in ammassi globulari Galattici. Le BSS sono ritenute essere significativamente più massicce delle stelle che tipicamente popolano un ammasso stellare. Questi oggetti sono facilmente identificabili durante la loro fase di bruciamento dell'idrogeno, al contrario è impossibile distinguerli fotometricamente, in modo certo, dalle altre stelle di minore massa del sistema che li ospita durante le fasi evolutive successive. In questo lavoro è stato applicato il metodo spettroscopico utilizzato da Ferraro et al. (2016) per identificare una E-BSS nell'ammasso globulare 47 Tuc e basato sul confronto tra le abbondanze chimiche derivate da righe spettrali neutre e ionizzate. Tale metodo permette di ricavare una stima della gravità a superficiale e, quindi, della massa stellare. In particolare, sono stati analizzati spettri ad alta risoluzione, acquisiti con lo spettrografo ad alta risoluzione UVES, di un campione 13 stelle candidate E-BSS dell'ammasso globulare M80 situate nella regione del CMD tra l'HB e l'attacco dell'AGB. I principali risultati di quest'analisi hanno mostrato che nel campione analizzato non vi sono E-BSS particolarmente massicce e, inoltre, hanno evidenziato una sottostima sistematica dell'abbondanza chimica ricavata da righe neutre in tutte le stelle di post-RGB, mentre le righe ionizzate risultano il diagnostico più u robusto ed affidabile per derivare le abbondanze chimiche.

La tesi affronta metodi e tecnica di rilievo e restituzione grafica digitale, applicati al caso di studio della Sala dei Filosofi a Villa Adriana, dopo il restauro iniziato nel 2014 e finito nel 2016. L'importanza della restituzione digitale della Sala dei Filosofi è legata alla prossimità di questa al più celebre edificio di Villa Adriana, il Teatro Marittimo, e al fatto che il suo studio nel rapporto con questo è sempre stato finora realizzato solo superficialmente, attraverso rilievi planimetrici. La tesi si compone di due parti distinte: la prima realizzata in situ, la "campagna di rilievo" per l'acquisizione dei dati; la seconda di elaborazione di questi, "post processing". Lo strumento utilizzato per il rilievo è un Laser Scanner modello C5 della Leyca che attraverso la creazione di nuvole di punti, lavorate successivamente in Cyclone - programma della medesima casa produttrice - ha permesso di estrapolare piante, sezioni e viste assonometriche. Una volta esportate in Autocad si è proceduto con le analisi geometriche della Sala, che hanno evidenziato analogie con altri edifici di quell’epoca, nella fattispecie la Basilica di Palazzo Flavio sul Palatino. L’obiettivo fondamentale di documentazione di un manufatto di Villa Adriana poco studiato si unisce a studi maggiormente specifici riguardo le affinità geometriche con la Basilica del Palazzo Flavio sul Palatino a Roma.

La tesi affronta lo studio di Villa Adriana con particolare riferimento al Teatro Marittimo; lo studio si propone di descrivere in modo dettagliato l’esperienza del rilievo attraverso le moderne tecnologie di acquisizione digitale, specificando le procedure che hanno permesso la fedele ricostruzione tridimensionale del Teatro Marittimo . Gli strumenti di rilievo Laser scanner - LS Leica modello C-5 - hanno consentito di condurre una campagna di rilievo finalizzata alla ricostruzione accurata e fedele dello stato dei luoghi post restauro del 2016, condotta durante la settimana del Workshop internazionale di rilievo archeologico e modellazione 3D svolto dal 26 Agosto al 2 Settembre 2017. I dati acquisiti sono stati integrati tra loro e successivamente elaborati mediante il software Cyclone, della medesima casa produttrice, al fine di ottenere il modello 3D oggetto della tesi. Lo studio svolto, tuttavia, non si limita alla documentazione digitale del Teatro Marittimo ma affronta e approfondisce forme ed edifici accessori posti in adiacenza a questo, documentando questo complesso con elaborati 3D e 2D (piante, sezioni, assonometrie) in grado di mettere in luce le connessioni con la Biblioteca e La Sala Dei Filosofi.

La tesi “Restituzione grafica della cosiddetta Casa Colonica a sud dell’area di Palazzo di Villa Adriana” si pone l'obiettivo di fornire una documentazione digitale della cosiddetta Casa Colonica mediante un modello tridimensionale realizzato con il software 3D Leica Geosystems Cyclone e l'estrazione da questo di elaborati tecnici significativi. La struttura della tesi segue le fasi del processo che a partire dal rilievo porta alla generazione di elaborati bidimensionali di documentazione tecnica di Beni Culturali, articolandosi in tre fasi ben distinte: la prima riguarda la ricerca storica della Villa imperiale, studiando approssimativamente l’intero complesso della villa per poi approfondire il caso di studio; la seconda riguarda la fase di rilievo spiegando la metodologia di rilievo, la strumentazione utilizzata e le varie operazioni svolte per ottenere il rilievo completo sotto forma di nuvola di punti; la terza riguarda la realizzazione degli elaborati: pianta della Casa Colonica; sezione longitudinale e trasversale. Non è secondaria la parte conclusiva di studio della pianta, per verificare le dimensioni di ogni singolo ambiente riferendole alla maglia compositiva basata sull’unità di misura romana, il piede (pes).

Questa lavoro di tesi nasce durante il periodo di tirocinio svolto presso la società di servizi Energika srl di Rimini in affiancamento all’Ufficio Tecnico, concentrandomi sull’attività di diagnosi energetica. Dopo una descrizione del panorama energetico europeo e italiano, si sono voluti affrontare sia aspetti più tecnici che altri meno pratici legati all’attività di diagnosi energetiche: gli obblighi normativi, i suggerimenti ministeriali sulla stesura, la figura dell’energy auditor e l’importanza del cambiamento di mentalità per il successo dell’efficienza energetica. La tesi procede poi seguendo lo schema di un audit vero e proprio. Si parte dallo studio del processo produttivo dell’azienda fino alla raccolta delle bollette di fornitura di elettricità e gas naturale. In seguito a tutte le informazioni raccolte, si sono costruiti i bilanci energetici per allocare i consumi ai diversi reparti e identificare quelli più energivori. Una parte importante del lavoro poi è stata la creazione e lo studio di indici di prestazione energetica. Attraverso la creazione degli indici di consumo specifico è stato possibile commentare le performance energetiche di questa azienda con lo scorrere degli anni e in confronto ad altre realtà industriali. Infine, si sono studiate diverse possibilità di efficientamento, sia elettrico che termico, per il sito in esame. Le varie tecnologia innovative proposte sono analizzate e confrontante attraverso un’analisi costi/benefici.

The High-luminosity project of the LHC calls for the employment of a new technology of superconducting magnets, which will make use of a material never used before, Nb3Sn. Some of the dipole magnets will be replaced inside the accelerator to enhance the collimating system of the beams and will be capable of producing magnetic fields in the order of 12 T, against the 8 T of the present machine. Experimental tests were conducted at the cryogenic laboratory at CERN to study the thermal behavior of a sample of the 11 T dipole under AC losses, with typical values of the input power density in the order of the mW/cmᵌ. The sample was inserted into an open box of insulator, to get closer to real operation. This thesis, which was carried out at the MSC (Magnets, Superconductors and Cryostats) Group at CERN, regards the development of a 1-D model of a radial line crossing the middle plane of a quadrant of the magnet. It is also representative of the materials in the section and it was used with the aim to study the temperature evolution and steady-state profiles in response to heat injections in the conductors, similar to those provided in the experiment. The same model was adapted to reproduce results of quench tests carried out at the SM-18 facility on short models of the 11 T dipole. In such tests, inductive heaters were energized to release heat in the magnet, in order to trigger the quench phenomenon, starting from given operating conditions of current and field. Using magnetic field maps together with the parametrization of the superconducting material, it was possible to derive local values of the T_cs, thus employing the magnet as a temperature probe. This work presents a detailed description of the model and of the hypothesis made to run the simulations, together with its validation obtained through the comparison with experimental tests cited above.
