Explorations is a three-movement experimental work for eighteen-piece jazz ensemble consisting of the following instruments: soprano saxophone, alto saxophone, two tenor saxophones, baritone saxophone, two trumpets, two flugelhorns, three trombones, bass trombone, electric guitar, vibraphone, contrabass, drums and piano. The duration of the work will approximate twelve minutes. The first movement features geometric configurations of spatially notated sound which emphasize percussive qualities of the ensemble (i.e. key clicks, tongue slaps, mouthpiece pops, etc.). Tone clusters of various pitch, texture and dynamics derived from blues scales provide the source material for the second movement. A slowly developing dynamic counterpoint creates the sound mass texture and delineates the form. Movement Three features a contrapuntal poly-metric collage of variations on a four-note theme. The collage provides the background fabric for an exchange of periodic and aperiodic events.

Air pollution can lead to environmental impacts. Over the past decades there have been some success stories reducing pollutant emission, namely sulphur dioxide (SO2). However, impacts on ecosystems from atmospheric nitrogen (N) pollution are still seen as a major threat for European biodiversity. Across Europe over 70% of Natura 2000 sites are at risk for eutrophication with over 70% of the Natura 2000 area in Europe (EU28( exceeding critical loads for nutrient nitrogen deposition. Agricultural ammonia is a key contributor to the threat to these sites due to the close proximity of agricultural activities and protected sites. Source attribution modelling using an atmospheric transport model showed that agricultural livestock production in the UK is the dominant nitrogen source for N disposition across the UK Natura 2000 network. Nearly 90% of all sites had livestock as their dominant source, contributing 32% of the total nitrogen deposition across the whole network. 76% of all Special Areas of Conservation (SAC) sites exceeded their critical load for nutrient nitrogen, representing 74% of the entire SAC area. The extent of exceedance is also notable with many sites experiencing depositions of >50 kg N/ha/yr over the critical load. the situation for acidity critical load exceedance is less sever, by 51% of sites are still exeeded. Legislation to regulate pollutant emissions to air and protect biodiversity are often not integrated, and there has been no common European approach for determining the impacts of nitrogen deposition on individual Natura sites, or on conservation status. Off-site sources of air pollution present difficulties in assessing and attributing impacts, because deposition can result from local sources (1-2 km), or very far away sources (>1000 kms). Managing nitrogen losses on the farm and improving the efficient use of nitrogen are key components for overall reduction in NH3 emissions. Many nitrogen management options are available to abate ammonia from agricultural activities. On the one hand, technical and management measures include controlling emissions from manure storage and spreading, livestock feeding strategies, and improving housing systems. Trees, on the other hand, are effective scavengers of both gaseous and particulate pollutants from the atmosphere, making tree belts potentially effective landscape features to support ammonia abatement strategies. Using a coupled deposition and turbulence model the recapture efficiency of tree planting around ammonia sources was estimated. Using different canopy structure scenarios, tree depths and differing leaf area density (LAD) and leaf are index (LAI) were adjusted for a main canopy and a backstop canopy. Recapture efficiency for ammonia ranged from 27% (trees planted around housing systems), up to 60% (under-story livestock silvopastoral systems). Practical recapture potential was set at 20% and 40% for housing and silvopastoral systems respectively. Model results from scaling up to national level suggest that tree planting in hot spot areas of ammonia emissions would lead to reduced N deposition on nearby sensitive habitats. Scenarios for on-farm emission control through tree planting showed national reductions in nitrogen deposition to semi-natural areas of 0.14% (0.2 kt N-NHx) to 2.2% (3.15 kt N-NHx). Scenarios mitigating emissions from cattle and pig housing yielded the highest reductions. The afforestation strategy showed national-scale emission reductions of 6% (8.4 kt N-NHx) to 11% (15.7 kt N-NHx) for 25% and 50% afforestation scenarios respectively. Increased capture by the planted trees also generated an added benefit of reducing long-range transport effects, including a decrease in wet deposition of up to 3.7 kt N-NHx (4.6%) and a decrease in export from the UK of up to 8.3 kt N-NHx (6.8%). Agroforestry measures for ammonia abatement were shown to be cost-effective for both planting downwind of housing and in silvopastoral systems, when costs to society were taken into account. Planting trees was also cost-effective from a climate change perspective. Comparing the cost per kg of NH3 abated showed that planting trees is a method of ammonia emission mitigation comparable with other (technical) measures. The costs for planting trees downwind of housing were calculated at €2.6-7.3/kg NH3. Agroforestry for ammonia abatement offers multiple benefits for the farmer and synergistic effects for society as a whole including i) carbon sequestration. ii) visibility screening around housing units, iii) imporved animal welfare for silvopastoral systems, iv) reducing critical load exceedance on protected sites, v) price advantage of 'woodland chick' productions, vi) supporting the Industrial Emission Directive (IED) requirements for emission reduction, vii) supporting national afforestation policies. The results of this work support the notion that in the emerging discussion about the values of ecosystem services and the role of nature-based solution to tackle persistent environmental challenges, tree planting has a large potential in rural and urban environments.

A base conceitual do mesmo, apresentando temas como serviços, Gestão da Qualidade e controle e avaliação de desempenho, permitiu elaborar um conjunto genérico de indicadores que pudesse atender algumas especificidades das empresas de serviços, quanto ao seu tipo de processo, e ao requisito de medição da norma ISO 9001:2000. Os indicadores propostos foram definidos de modo que eles pudessem desencadear uma relação de causa e efeito, interligando-os em cinco perspectivas. Foram realizadas visitas a cinco empresas de serviços da região metropolitana do Recife, para análise de seus sistemas de medição de desempenho e comparação com o conjunto de indicadores propostos, a partir da classificação das empresas quanto ao tipo de processo, onde se esperava observar alguns dos indicadores sendo medidos e o porquê de outros não serem medidos. Nesta análise, pode-se observar uma variedade de modelos de medição de desempenho, com medidas isoladas entre áreas e sem relação com a estratégia da empresa. Com relação ao conjunto de indicadores propostos, foi observado que são passíveis de serem mensurados e importantes de serem avaliados por estas organizações. O modelo elaborado neste trabalho tem como objetivo propor um grupo equilibrado de medidas essenciais e seus correspondentes indicadores para auxiliar as empresas de serviços a avaliar seu desempenho, baseado na metodologia da Balanced Scorecard e considerando as limitações presentes quanto aos segmentos de serviços selecionados

Nele, o enfoque dado foi ao processo de implementação do Sistema de Gestão da Qualidade (SGQ) na Construção Civil, tendo sido explanada a normalização existente referente à qualidade, desde a série de normas ISO 9000:2000 até as políticas de qualidade voltadas a este segmento. O modelo de implementação de três autores, a atuação dos ambientes da qualidade on-line, in-line e off-line e os oito princípios de qualidade foram abordados. Foram pesquisadas quatro construtoras da Região Metropolitana do Recife com entrevistas, questionários e visitas técnicas. A partir dos dados coletados e pesquisados, foi elaborado um modelo, intitulado Pontos Chaves do Processo de Implementação, composto por onze etapas, que tem como objetivo auxiliar as empresas a implantarem o SGQ ou a reavaliarem seu sistema de maneira eficaz. Três importantes etapas, não muito exploradas na literatura, foram enfatizadas no modelo: aspectos que impulsionaram a implementação, diagnóstico crítico e melhoria contínua. A primeira apresenta a importância de se trabalhar pró - ativamente tendo como motivação a satisfação do cliente e um produto final com qualidade. A segunda retrata a realidade do processo produtivo e serve de base para a tomada de decisões. A terceira exige a interação dos três ambientes da qualidade e o envolvimento de pessoas de todos os setores com visões diferentes do processo

114 Resumé The topic of my diploma thesis is "Legal regulation of Natura 2000 Network". Natura 2000 is a a network that seeks to preserve biodiversity within the territory of the EU. Natura 2000 was imposed by the article 3 of the Habitats Directive, which along with the Bird Directive are the most important legal acts aiming at biodiversity conservation in the European Union. The main purpose of this work is the legal analysis of the legal arangement of the Natura 2000 Network by taking the european context under consideration. First three chapters describes the concept of Natura 2000 Network and its history, including a short description of biodiversity protection within the internatinal law (relevant international agreements). The next chapter is focused on the European Union Law. Firstly, it describes the history of environmental policy within the european law and the institutions and funds connected to Natura 2000 Network. The law base of Nature 2000 network is formed by the European Directive 2009/147/EEC on the conservation of the wild birds (so called "Birds Directive") and the European Directive 92/43/EEC on the conservation of the natural habitats and of wild fauna and flora (so called "Habitats Directive"). These directives enable designation of two types of protected areas - Special Protected...
