Abstract (sommario):
Ziel dieser Arbeit war es, das Potenzial von p-tert-Butyltetramercaptotetrathiacalix[4]aren (H4(MTC[4])) zum Aufbau von mehrkernigen Komplexen mit weichen Metallionen mit d10-Elektronenkonfiguration zu untersuchen. H4(MTC[4]) bietet im Vergleich zum bekannteren p-tert-Butylcalix[4]aren erweiterte Bindungsmöglichkeiten für Metallionen an den Thioetherbrücken. Die Funktion der Metallionen Cu(I) und Zn(II) in biologischen Systemen lieferte die anfängliche Inspiration, jedoch erschien auch die Untersuchung anderer Metalle wie Nickel, Silber und Gold in Verbindung mit (MTC[4])4- Liganden lohnenswert, da diese Metalle durch ihre jeweils bevorzugten Koordinationsgeometrien neue Strukturen und Koordinationsmöglichkeiten an H4(MTC[4]) aufzeigen könnten. In Experimenten mit Kupfer(I)-Ionen konnten der Kupferkomplex [(Ph3PCu)4(MTC[4])] sowie das Hexamer [Cu4(MTC[4])]6 hergestellt und charakterisiert werden. [Cu4(MTC[4])]6 weist eine einzigartige, supramolekulare, hohle Cu24S48-Käfigstruktur auf. Die [Cu4(MTC[4])]-Einheiten werden durch Cu2S2-Motive verknüpft, die extrem kurze Cu···Cu-Abstände aufweisen. Durch NMR-Experimente wurde gezeigt, dass die Hohlräume von [Cu4(MTC[4])]6 in Lösung Acetonitril und Methan aufnehmen können. In Experimenten mit Silber(I)-Ionen wurden die Molekülstrukturen der Silberkomplexe [(Ph3PAg)2AgH(MTC[4])], [(Ph3PAg)4AgCl(MTC[4])] und [(Ph3PAg)4(MTC[4])] bestimmt. Diese zeigen, dass H4(MTC[4]) gegenüber Silber- und Kupferionen ein ähnliches Koordinationsverhalten aufweist. In Experimenten mit Gold(I)-vorläufern war es möglich, zu steuern, wie viele Metallionen ein einzelnes Molekül H4(MTC[4]) koordiniert. Die Komplexe [(Ph3PAu)2H2(MTC[4])], [(Me3PAu)3H(MTC[4])] und [(Me3PAu)4TlCl(MTC[4])] wurden synthetisiert. Diese bieten teilweise durch vorhandene freie Thiolfunktionen Potenzial für die Synthese heterometallischer Komplexe.
It was the aim of this work, to assess the potential of p-tert-Butyltetramercaptotetrathiacalix[4]arene (H4(MTC[4])) to create multinuclear complexes with soft metal ions of d10 electron configuration. In contrast to the more known p-tert-Butylcalix[4]aren, H4(MTC[4]) offers extended possibilities for the coordination of metal ions at the thioether groups. While this work was initially inspired by the function of Cu(I) and Zn(II) ions in biological systems, the metal ions, which were incorporated into the Calixarene, were soon expanded by Ni(II), Ag(I) and Au(I) ions. Through their different preferred coordination geometries, these metal ions could yield new information about coordination modes of H4(MTC[4]). In experiments with copper(I) ions the complex [(Ph3PCu)4(MTC[4])] and the hexamer [Cu4(MTC[4])]6 were synthesized and characterized. [Cu4(MTC[4])]6 consists of a unique, supramolecular hollow Cu24S48 cage structure. The [Cu4(MTC[4])] units are connected by Cu2S2 motivs, which display extraordinary short Cu···Cu distances. An investigation by NMR spectroscopy indicated that the cavities of [Cu4(MTC[4])] in solution can hold acetonitrile or methane molecules. In experiments with silver(I) ions, the molecular structures of the compounds [(Ph3PAg)2AgH(MTC[4])], [(Ph3PAg)4AgCl(MTC[4])] and [(Ph3PAg)4(MTC[4])] were determined. In these compounds H4(MTC[4]) exhibits a similar coordination behaviour towards Ag(I) ions as it does towards Cu(I) ions. In experiments with gold(I) precursors it was possible to control how many gold(I) ions were coordinated by H4(MTC[4]). The complexes [(Ph3PAu)2H2(MTC[4])], [(Me3PAu)3H(MTC[4])] and [(Me3PAu)4TlCl(MTC[4])] were synthesized and studied. Due to their free thiol functions, they are potential precursors for the synthesis of heterometallic complexes.

Abstract (sommario):
The current energy situation is taking a turn towards renewable energies, due to the new pacts to curb global warming. These agreements, together with governmental aid, are facilitating an escalation in the production and improvement of new energy systems and the price decrease due to a larger-scale production. Within these energy alternatives, solar energy is found, specifically the subject to be treated in this project is photovoltaic energy, due to its exponential growth in the last 10 years, new tools are being developed for its monitoring and modelling. Therefore, the main objective of this thesis is to develop a method  for installation testing of a PV-system. The method should give the installed nominal power of the system and show if the maximum power point trackers work as expected. A large PV-system was installed on the roof of Gävle Arenaby during 2017. A measurement system for monitoring of the power of the system and of the solar irradiance was installed. Different parameters have been taken into account for the adjustment of the model that vary the performance of the system. These factors are: the irradiance received, the module temperature and the angle of incidence. It has been concluded that the results obtained indicate a correct adjustment of the theoretical power against the real power, which means, a correct operation of the generated model. Besides, the expected power follows a linear trend, reaching the power set by the manufacturer for Standard Test Conditions. The results show that the monitored modules-strings fulffill the promised performance and the method for installation testing work as expected. The linear correlation between corrected power and irradiance means that the maximum power point tracker in the inverter works independent of the power.

Abstract (sommario):
El compost dímer [{RuCl2(p-cimè)}2] reacciona amb diferents lligands fosfina donant pas a la formació dels compostos monòmers de ruteni(II) [RuCl2(p-cimè)L] on L = PPh2H, PPh2(CH2)xpy (on x = 0 i 1) i PPh2C∫CR (on R = Ph, tBu i p-Tol). Si se'l fa reaccionar amb la fosfina PPh2C∫CPPh2 s'obté el compost d'estequiometria [{RuCl2(p-cimè)}2PPh2C∫CPPh2] on la fosfina actua com a lligand bidentat pont entre dos àtoms de ruteni. Quan es fan reaccionar els compostos [RuCl2(p-cimè)PPh2(CH2)xpy] amb NaBF4 s'obtenen els compostos [RuCl(p-cimè)PPh2py]BF4 i [RuCl(p-cimè)PPh2CH2py]BF4. En aquests compostos la fosfina actua com a lligand quelant P-N.
L'estudi cristal·logràfic efectuat confirma les estructures proposades per als compostos [RuCl2(p-cimè)PPh2H], [RuCl2(p-cimè)PPh2py] i [RuCl2(p-cimè)PPh2py]BF4. El compost [RuCl2(p-cimè)PPh2C∫CPh] cristal·litza formant dos tipus de cristalls diferents amb dues estructures pràcticament idèntiques, amb l'única diferència de l'orientació dels anells fenil units directament al fòsfor en relació a l'anell del p-cimè.
Els compostos [RuCl2(p-cimè)PPh2py] i [RuCl(p-cimè)PPh2py]BF4 actuen com a catalitzadors de la hidrogenació catalítica de substrats com olefines i alquins. Els rendiments són comparables als obtinguts amb altres catalitzadors malgrat que la cinètica és més lenta.

El dímer [Ru2(HCOO)2(CO)4(PPh2py)2] reacciona amb ditiols formant els corresponents complexos [Ru2(S(CH2)xS)(CO)4(PPh2py)2] (on x = 2 i 3) en els quals el lligand ditiolat actua com a lligand pont i la fosfina com a lligand terminal.

El complex [Ru(HCOO)(CO)2(PPh2CH2py)]HCOO reacciona amb el ditiol HS(CH2)2SH donant lloc al compost [Ru(S(CH2)2S)(CO)2(PPh2CH2py)] en el qual els lligands ditiolat i fosfina actuen com a lligands quelants.
El compuesto dímero [{RuCl2(p-cimeno)}2] reacciona con diferentes ligandos fosfina dando lugar a la formación de los compuestos monómeros de rutenio(II) [RuCl2(p-cimeno)L] con L = PPh2H, PPh2(CH2)xpy (x = 0 y 1) y PPh2C∫CR (con R = Ph, tBu y p-Tol). Si se hace reaccionar este dímero con la fosfina PPh2C∫CPPh2 se obtiene el compuesto de estequiometría [{RuCl2(p-cimeno)}2PPh2C∫CPPh2] en el que la fosfina actúa como ligando bidentado puente entre dos átomos de rutenio. Cuando se hacen reaccionar los compuestos [RuCl2(p-cimeno)PPh2(CH2)xpy] con NaBF4 se obtienen los compuestos [RuCl(p-cimeno)PPh2py]BF4 y [RuCl(p-cimeno)PPh2CH2py]BF4. En éstos, la fosfina actúa como ligando quelante P-N.
El estudio cristalográfico efectuado confirma las estructuras propuestas para los compuestos [RuCl2(p-cimeno)PPh2H], [RuCl2(p-cimeno)PPh2py] y [RuCl2(p-cimeno)PPh2py]BF4. El compuesto [RuCl2(p-cimeno)PPh2C∫CPh] cristaliza formando dos tipos de cristales diferentes con dos estructuras prácticamente idénticas, con la única diferencia de la orientación de los anillos fenilo unidos directamente al fósforo en relación al anillo del p-cimeno.
Los compuestos [RuCl2(p-cimeno)PPh2py] y [RuCl(p-cimeno)PPh2py]BF4 actúan como catalizadores de la hidrogenación catalítica de substratos como olefinas y alquinos. Los rendimientos son comparables a los obtenidos con otros catalizadores aunque la cinética es más lenta.
La reacción de Ru3(CO)12 con la fosfina PPh2py en exceso de ácidos carboxílicos da lugar a los complejos dímeros de Ru(I) [Ru2(HCOO)2(CO)4(PPh2py)2] y [Ru2(CH3COO)2(CO)4(PPh2py)2] en los que el ligando carboxilato actúa como ligando puente y la fosfina actúa como ligando terminal. El dímero [Ru2(HCOO)2(CO)4(PPh2py)2] reacciona con ditioles formando los correspondientes complejos [Ru2(S(CH2)xS)(CO)4(PPh2py)2] (x = 2 y 3) en los que el ligando ditiolato actúa como ligando puente y la fosfina como ligando terminal.
La reacción de Ru3(CO)12 con la fosfina PPh2CH2py en presencia de un exceso de ácidos carboxílicos da lugar a los complejos monómeros de Ru(II) [Ru(HCOO)(CO)2(PPh2CH2py)]HCOO y [Ru(CH3COO)(CO)2(PPh2CH2py)]CH3COO en los que los ligandos carboxilato y fosfina actúan como ligandos bidentados. El complejo [Ru(HCOO)(CO)2(PPh2CH2py)]HCOO reacciona con el ditiol HS(CH2)2SH formando el compuesto [Ru(S(CH2)2S)(CO)2(PPh2CH2py)] en el qual los ligandos ditiolato y fosfina actúan como ligandos quelantes.
The dimeric compound [{RuCl2(p-cymene)}2] reacts with different phosphine ligands to give the monomeric ruthenium(II) compounds [RuCl2(p-cymene)L] with L = PPh2H, PPh2(CH2)xpy (x = 0 and 1) and PPh2C∫CR (with R = Ph, tBu and p-Tol). Reaction with PPh2C∫CPPh2 leads to the compound [{RuCl2(p-cymene)}2PPh2C∫CPPh2], where the ligand acts as a bridge between two ruthenium atoms. When compounds [RuCl2(p-cymene)PPh2(CH2)xpy] react with NaBF4, [RuCl(p-cymene)PPh2py]BF4 and [RuCl(p-cymene)PPh2CH2py]BF4 are obtained. In these compounds, the phosphine ligands act as chelating P-N molecules.
The crystallographic study confirms the structures proposed for compounds [RuCl2(p-cymene)PPh2H], [RuCl2(p-cymene)PPh2py] and [RuCl2(p-cymene)PPh2py]BF4. The structure of [RuCl2(p-cymene)PPh2C∫CPh] shows two type of crystalls with practically identical structure. The only difference is the orientation of phenyl rings directly linked to phosphorous.
Compounds [RuCl2(p-cymene)PPh2py] and [RuCl(p-cymene)PPh2py]BF4 catalyse the hidrogenation of substrates such as olefines and alkynes. The yields are comparable to those obtained with other catalysts although the kinetics are slower.
The reaction of Ru3(CO)12 with PPh2py with an excess of a carboxylic acid leads to the dimeric Ru(I) complexes [Ru2(HCOO)2(CO)4(PPh2py)2] and [Ru2(CH3COO)2(CO)4(PPh2py)2] in which the carboxylate ligands act as a bridge and the phosphine acts as a terminal ligand. The dimeric compound [Ru2(HCOO)2(CO)4(PPh2py)2] reacts with dithiols forming the corresponding complexes [Ru2(S(CH2)xS)(CO)4(PPh2py)2] (x = 2 and 3) in which the dithiolate ligands act as bridging molecules and the phosphine acts as a terminal ligand.
The reaction of Ru3(CO)12 with PPh2CH2py in the presence of an excess of carboxylic acids gives the monomeric Ru(II) compounds [Ru(HCOO)(CO)2(PPh2CH2py)]HCOO and [Ru(CH3COO)(CO)2-(PPh2CH2py)]CH3COO in which carboxylate and phosphine act as bidentate ligands. The complex [Ru(HCOO)(CO)2(PPh2CH2py) ]HCOO reacts with 1,2-ethanedithiol forming the compound [Ru(S(CH2)2S)(CO)2(PPh2CH2py)] where dithiolate and phosphine ligands act as chelating ligands.

The waste pickers perform an important public utility service in the current context of the cities, working in waste pickers which, when discarded, would occupy more space in landfills and dumps. The Law 12.305/10 recognizes, appreciates and clarifies the importance of active participation of the category with the government regarding the management of solid waste. However, the reality experienced by these professionals is characterized as unhealthy due to poor infrastructure and lack of technologies to develop their activities, favoring a danger scenario a nd exposure to occupational hazards and damage to health. This work aimed to evaluate, develop and implement technological and infrastructure alternatives to reduce occupational hazards in the professional practice of waste pickers linked to ARENSA, Campina Grande-PB. The participant survey was conducted from October 2014 to December 2015 with 16 waste pickers associated with ARENSA (Waste Pickers Association of Community Nossa Senhora Aparecida) operating in Campina Grande-PB. It found the frequency and severity of physical risks (exposure to sunlight and temperature changes), chemical (dust, smoke) biological (exposure to microorganisms and macrovetores), ergonomic (intense physical effort, lifting and manual transport weight; requirement of poor posture, prolonged use of voice, conflict and stress) and accidents (fires; sharps; landslides bags of pedestrian accidents and falls). To reduce the source of the danger and minimize risks to improving the working environment were developed three social technologi es: a collapsible cart for collection of solid waste with dimensions 100x120x150cm, dry weight 55 kg; a trolley platform for transport bags and bales during screening for packaging measuring 100x120x480cm and support for 350 kg; a dimension in sorting table 200x100x100cm and 20 cm depth. The technologies were developed with the participation of workers and observing the dynamics of work and ergonomic parameters in order to reduce the physical effort of the group. One can gauge the effectiveness in mitigating the ergonomic and accidents with lifting and carrying weight reduction, lower demand for improper posture and aggravating diseases physical health of the worker. To reduce accidents by trampling have changed the uniforms with reflective fabric application (NBR 15292/2013), peaked at other positive impacts, such as professional development. Besides the acquisition of personal protective equipment (boots, gloves, rain gear, protective cap and Arabic glasses) enabled the worker protection with regard to exposure to physical, chemical, biological. So the alternatives applied favored the reduction of occupational hazards, contributing to the implementation of activities and the appreciation of the profession waste pickers.
Os catadores de materiais recicláveis realizam um serviço de utilidade pública muito importante no contexto atual das cidades, atuando na coleta de materiais que ao serem descartados indevidamente, ocupariam maior espaço em aterros sanitários e lixões. A Lei 12.305/10, reconhece, valoriza e esclarece a importância da participação ativa da categoria junto ao poder público e à sociedade no tocante à gestão dos resíduos sólidos, contudo, a realidade vivenciada por estes profissionais caracteriza-se como insalubre, devido à precária infraestrutura e ausência de tecnologias para desenvolver as suas atividades, culminando num cenário de perigo e exposição a riscos ocupacionais e danos à saúde. Este trabalho teve como principal objetivo avaliar, desenvolver e implantar alternativas tecnológicas e de infraestrutura para reduzir riscos ocupacionais no exercício profissional de catadores de materiais recicláveis vinculados à ARENSA, Campina Grande-PB. A pesquisa participante foi efetivada de outubro de 2014 a dezembro de 2015 com 16 catadores de materiais recicláveis associados à ARENSA (Associação de Catadores de Materiais Recicláveis da Comunidade Nossa Senhora Aparecida) atuantes em Campina Grande-PB. Constatou-se a frequência e gravidade de riscos físicos (exposição à radiação solar e mudanças de temperatura), químicos (poeira; fumo), biológicos (exposição a microrganismos e macrovetores), ergonômicos (esforço físico intenso, levantamento e transporte manual de peso; exigência de postura inadequada; uso prolongado de voz; conflitos e stress) e de acidente (incêndios; perfuro-cortantes; desmoronamentos de bags, atropelamentos e quedas). Com intuito de reduzir o perigo e minimizar os riscos para melhoria do ambiente de trabalho foram desenvolvidas três tecnologias sociais: um carrinho desmontável para coleta de resíduos sólidos com dimensões 100x120x150 cm e peso seco 55 kg; um carrinho plataforma para transporte de bags e fardos da triagem ao acondicionamento, medindo 100x120x480 cm e suporte para 350 kg; uma mesa de triagem em dimensões 200x100x100 cm e 20 cm de profundidade. As tecnologias foram confeccionadas com a participação dos trabalhadores e observando-se a dinâmica do trabalho e os parâmetros da ergonomia como a redução do esforço físico manual. Pode-se aferir a eficiência na mitigação dos riscos ergonômicos e de acidente com redução de levantamento e transporte de peso, menor exigência de postura incorreta e de agravantes à saúde física do trabalhador. Para redução dos riscos de acidente por atropelamento, foram modificados os fardamentos com aplicação de tecido reflexivo (ABNT NBR 15292/2013), proporcionando outros impactos positivos, como a valorização profissional. Ademais a aquisição de equipamentos de proteção individual (botas, luvas, capa de chuva, óculos protetor e boné árabe) propiciou a proteção do trabalhador no que se refere à exposição de riscos de ordem física, química, biológica e ergonômico. Portanto, as alternativas aplicadas foram positivas à redução dos riscos ocupacionais, favorecendo a execução das atividades e a valorização profissional dos catadores de materiais recicláveis.

Smith, Gregory Michael. "Performance Practice Issues in Russian Piano Music". Thesis, 2003. http://hdl.handle.net/1959.13/24961.

Testo completo
Abstract (sommario):
The nineteenth and twentieth centuries witnessed the rapid growth of musical culture in Russia. This resulted in a large repertoire of piano music — ranging from miniatures to virtuosic etudes and sonatas. Growing out of the nineteenth century romantic tradition, and highly influenced by the social conditions of the time, Russian composers developed a distinctive style which closely reflected their culture, personalities and ideologies. There are several approaches to studying performance practice. One is to study the interpretations of other pianists. While this does have many advantages, it has not been adopted in this paper as it has one flaw: it still fails to capture the distinctive language of these composers. Rather, the paper will study the social and musical influences on the composers, and, more importantly, their philosophies about pianism and the purpose of music. This will be related to interpretative issues in the works. The repertoire has been divided into four areas. The paper commences with a study of the miniature, which is valuable in finding the ‘essence’ of a composer’s musical language expressed on a small scale. Here, the ‘elementary’ considerations in performance practice will be studied. The second chapter discusses etudes. This is useful in gaining an insight into composers’ conception of technique, and how this relates to performance practice. The third chapter deals with music that has extra-musical themes. This provides opportunity for a more detailed cultural and biographical study of the composers. To represent the large-scale repertoire of Russian composers, the sonata will be studied. Here, a detailed analysis of the composers’ musical language and its relationship to expression will be discussed.
