Resumo: Atualmente o Brasil apresenta 7,8 milhões de hectares de árvores plantadas para fins industriais, sendo cultivado principalmente o gênero Pinus e Eucalyptus, e em menor escala outras culturas florestais. Entre essas culturas destaca-se o gênero Populus, com 4216 ha de plantios, sendo empregado principalmente para produção de palitos de fósforo. Dentre este gênero destaca-se a espécie deltoides, a qual não apresenta seu uso tão difundido, necessitando ser estudada para outros fins, como por exemplo, o seu emprego na confecção de painéis de colagem lateral - EGP. Este tipo de painel é formado pela união de sarrafos, lateralmente ou pela união de topo, através de ligação adesiva. Diante deste cenário, este trabalho teve como objetivo avaliar a viabilidade tecnológica do uso da madeira de Populus deltoides W. Bartram ex Marshall para a produção de painéis de colagem lateral - EGP. Para cumprir este objetivo, avaliou-se as propriedades químicas e físicas da madeira de Populus deltoides e Pinus taeda (testemunha), as propriedades dos adesivos PVA D3, PVA D4, EPI e MUF, e, testou-se as emendas de topo do tipo finger-joint colada com o adesivo PVA D3 por meio dos ensaios flexão estática e tração paralela, e, as juntas coladas efetivadas com os distintos adesivos na gramatura 180 g/m², por meio do ensaio mecânico de cisalhamento na linha de cola. A qualidade da colagem lateral e de topo da madeira de Populus deltoides foi comparada a madeira de Pinus taeda e com requisitos normativos. Os resultados obtidos, demostraram que Populus deltoides apresentou massa específica inferior, estabilidade dimensional e teor de cinzas superior a Pinus taeda. Para as juntas coladas e as emendas de topo, de acordo com a norma EN 13353 (EN, 2003) e a ASTM D 5572-95 (2005), a espécie Populus deltoides pura ou em mistura com o Pinus taeda, apresentou de modo geral potencial para a produção de EGP com os adesivos PVA D3, EPI e MUF. Palavras-chave: Populus deltoides; propriedades físico-químicas; colagem lateral; colagem de topo.
Abstract: Currently Brazil presents 7.8 million hectares of trees planted for industrial purposes, being cultivated mainly the genus Pinus and Eucalyptus as well as other forest cultures. Among these cultures, the genus Populus stands out with 4216 ha of reforestation used mainly for the production phosphorus sticks. Among this genus, the species deltoides is highlighted, which does not present its widespread use, and needs to be studied for other purposes, such as its use in the manufacture of edge glued panel - EGP.This type of panel is formed by the joining of battens, laterally or by the top joint, through adhesive bonding. In this scenario, the objective of this work was to evaluate the technological feasibility of the use of wood from Populus deltoides W. Bartram ex Marshall for the production of edge glued panel - EGP.In order to comply with this objective, the chemical and physical properties of the wood of Populus deltoides and Pinus taeda (control), the properties of the adhesives PVA D3, PVA D4, EPI and MUF, were evaluated. finger-joint bonded with the PVA D3 adhesive by means of the static bending and parallel traction tests, and the bonded joints effected with the different adhesives in the grammage 180 g / m², by means of the mechanical test of shear in the glue line. The quality of the lateral and top collage of the wood of Populus deltoides was compared to Pinus taeda wood and with normative requirements.The results showed that Populus deltoides hard lower specific mass, dimensional stability and ash content large than Pinus taeda. For the top and side gluing, according to EN 13353 (EN, 2003) and ASTM D 5572-95 (2005), the species Populus deltoides pure or in combination with Pinus taeda, presented in general a potential for the production of EGP with the adhesives PVA D3, EPI and MUF. Keywords: Populus deltoides; physicochemical properties; side gluing; top gluing.

OBJETIVO: Adaptar transculturalmente o Exame Geronto Psicomotor (EGP) e analisar suas evidências de validade. MÉTODOS: A amostra foi constituída por 51 idosos, 10 participaram da adaptação transcultural e 41 da etapa de avaliação das propriedades psicométricas do EGP. As variáveis analisadas foram: Validade de conteúdo, concordância entre juízes, consistência interna, estabilidade teste reteste e validades convergente e divergente. As etapas de adaptação transcultural foram: tradução para a Língua Portuguesa, síntese das traduções, tradução reversa, treinamento dos avaliadores, avaliação do comitê de especialistas e pré-teste. Para coleta de dados utilizou-se: Questionário social, Mine Exame do Estado Mental (MEEM), Sênior Fitness Test (SFT) e a versão brasileira do EGP. Na análise dos dados e tratamento estatístico foi utilizado o programa SPSS 22. A pesquisa foi aprovada pelo Comitê de Ética sob o parecer nº 1.223.636. RESULTADOS: Após a análise das equivalências e as modificações propostas pelo comitê de especialistas, a versão pré final do EGP passou por um pré-teste (Piloto) em um grupo de 10 idosos. Durante a adaptação transcultural foram realizadas diversas mudanças no EGP, desde o layout até os comandos do teste. O coeficiente de k demonstrou alto grau de concordância entre os juízes. O valor do alfa de Cronbach foi (α=0,69) e não houveram itens cuja retirada impactaria na melhora desse índice. A correlação entre os dois momentos de aplicação mostrou que o escore global da EGP possui boa estabilidade (r=0,98; p<0,01). CONCLUSÃO: O EGP foi adaptado com êxito para uso no Brasil e demonstrou ser um bom instrumento para traçar perfis individualizados, já que engloba tanto a parte quantitativa quanto a qualitativa da avaliação. Contudo, a aplicação com grande número de indivíduos se torna complexa.
OBJECTIVE: To Adapt cross-culturally the Geronto Psychomotor Exam (EGP) and analyze its evidence of validity. METHODS: The sample consisted of 51 elderly, 10 participated in the cross - cultural adaptation and 41 of the stage of evaluation of the psychometric properties of EGP. The variables analyzed were: contente validity, judges greement, internal consistency, test retest stability and convergent and divergent validities. The stages of cross-cultural adaptation were: translation into Portuguese, synthesis of translations, reverse translation, training of evaluators, evaluation of the committee of experts and pre-test. For data collection, were used: Social Questionnaire, Mine Mental State Examination (MEEM), Senior Fitness Test (SFT) and the Brazilian version of EGP. In the data analysis and statistical treatment the SPSS program 22 was used. The research was approved by the Ethics Committee under opinion nº 1,223,636. RESULTS: After the analysis of the equivalences and the modifications proposed by the expert committee, the pre-final version of the EGP underwent a pre-test (Pilot) in a group of 10 elderly people. During the cross-cultural adaptation several changes were made in the EGP, from the layout to the test commands. The coefficient of k showed a high degree of concordance between the judges. The value of Cronbach's alpha was (α = 0.69) and there were no items whose withdrawal would impact the improvement of this index. The correlation between the two application moments showed that the overall EGP score had good stability (r = 0.98, p <0.01). CONCLUSION: The EGP was adapted for use in Brazil and has proved to be a good tool for drawing individual profiles, since it encompasses both the quantitative and the qualitative aspects of the evaluation. However, application with large numbers of individuals becomes complex.

The use of pine wood is increasing and for the success of its products it is essential to have the know-how to work its features, advantages and disadvantages. The objective of this study is to evaluate the influence of batten widths and the physical arrangement of growth rings in Edge Glued Panel of Pinus taeda used in the manufacture of door frames, according the requirements of ABNT-NBR 15.930 (2011) to determine the best combination for better physical performance of the door frame. Experimental tests considered the full factorial method using two factors and four levels, with batten widths of 32mm, 56mm, 75mm and 112mm; and arrangement of the growth rings: radial, tangential, crossed and plates with top amendments type finger joint. The 48 samples (03 from each combination), with 2120 x 220 x 32 mm, with a moisture content between 8% and 12% and an apparent density between 400 kg.m-3 and 600 kg.m-3 were produced in a wood factory in Sengés/PR/Brasil. The statistical analysis of variance (ANOVA) was used to investigate the influence of the factors and their interactions in the following responses: visual appearance, moisture content variations, density variations, dimensional variations in width and thickness and deviations in shape (warping: bending, curving and curling). The results showed that both factors and their interactions exerted influence with a significance level of 1% on the deviations of form. The best results were to EGP produced with batten widths of 32 mm and 56 mm, with radial or crossed arrangement. The factors and their interactions did not significantly influence the other answers.

Abstract:

L'étude des processus de différenciation des EGP entreprise dans ce travail, nécessite leur dosage à des teneurs d'ultra-traces. Une méthode analytique de dosage a été développée. Elle met en oeuvre une extraction et une préconcentration basée sur une coprécipitation des EGP avec le sélénium et le tellure. L'analyse est effectuée par absorption atomique au four graphite. Les taux d'extraction, varient de 90 à 100 % pour Pt, Pd, Ru, Rh, et Au, et les limites de détection sont de l'ordre de 0,5 ppb . Les distributions des EGP observées dans les roches magmatiques, ont conduit à la distinction de deux groupes, l'un nommé IEGP ( Ir, Ru, Os) et un autre PEGP (Pt, Pd, Rh et Au). Les éléments du premier groupe sont exprimés sous forme de minéraux et se trouvent quasi exclusivement en inclusions au sein des cristaux de chromite . Par contre ceux du second se concentrent dans les sulfures de métaux de base (pentlandite, chalcopyrite). Ces associations suggèrent un rôle important de la fS2. et de la f02. dans le fractionnement des EGP. L' approche expérimentale de l'influence de ces deux paramètres, sur la solubilité d'un élément de chaque groupe, Ir et Pt, dans un bain silicaté à composition basaltique .( T= 1430° C), met en évidence, une diminution importante de la solublité de Ir avec une augmentation de la f02, ainsi qu'une forte augmentation de la solubilité du Pt pour une augmentation de la fs2. (fs2. > 1 0-2 at . ). Les résultats obtenus sont en parfait accord avec les observations microscopiques . De plus, ils nous ont conduit à rechercher l'origine des spectres en EGP très différents pour les chromitites de type stratiforme et podiforme, dans les conditions de formation de ces corps minéralisés . Nous proposons que ces conditions peuvent être comparées à un "système ouvert" pour les chromitites de type podiforme et à un '*système clos" , c' est-à-dire beaucoup plus confiné, pour les chromitites stratiformes. Dans ce modèle , nous confirmons l'importance de l'apparition de la saturation en soufre, sur le fractionnement des EGP, et montrons que ce dernier est à relier à l'évolution de la capacité en soufre du magma. De même, l 'étude de la distribution des EGP dans des roches ou phases minérales formées lors de la serpentinisation et la listwaenitisation des roches ultrabasiques mantelliques du complexe ophiolitique de Bou-Azzer (Maroc) a permis de mettre en évidence des phénomènes de fractionnement des EGP. Ce fractionnement se traduit par de nouveaux spectres en EGP attribués à des mobilités variables des EGP au cours des deux processus d'alteration postmagmatique. De Plus, les résultats obtenus montrent la faible solubilité de Pt ,Pd et Rh, par rapport à Au, dans les fluides hydrothermaux riches en. CO, As, Bl, ... , pour des T° de 150 à 300°C, ayant conduit , à la formatlon des concentrations en Au et Co dans les listwaenltes. Enfin, l 'étude des fractions de minéraux lourds , recueillis dans les alluvions de la Basse-Durance (France , a permis de mettre en évidence une paragenese complexe en MGP, avec comme minéral prédominant l' isoferroplatlne (Pt3Fe) . Une origine industrielle ou météoritique de ces paillettes est à rejeter . Les caractéristiques morphoscopiques observées suggèrent un long transport de ces paillettes. Le bassin versant de la haute Durance apparait comme une zone à fort potentiel pour contenir les roches sources de ces paillettes .

Inserido no contexto do Arco Magmático de Goiás, o Complexo máfico-ultramáfico Mangabal está associado a um conjunto de diversas intrusões neoproterozóicas formadas durante o a orogenia brasiliana, no centro do Brasil. Este trabalho tem como objetivo apresentar a evolução magmática e o metamorfismo do Complexo máfico-ultramáfico Mangabal. Para tanto foram realizados trabalhos de campo, descrição e amostragem de testemunhos de sondagem, descrições petrográficas em seções delgadas e polidas, química mineral, imageamento em microscópio eletrônico de varredura (MEV) e análises químicas isotópicas de isótopos de Sm e Nd. O Complexo Mangabal está inserido na Zona de Cisalhamento São Luís dos Montes Belos e é composto por dois corpos máfico-ultramáficos acamadados metamorfizados. O membro norte apresenta aproximadamente 6 km²; já o membro sul, distante aproximadamente 2 km do anterior, possui aproximadamente 29 km² de área em superfície. Ambos os corpos exibem a mesma mineralogia, sequência de cristalização ígnea e composição química mineral. A estratigrafia do Complexo de Mangabal pode ser dividida em três zonas principais: i. Zona Máfica Inferior, localizada na porção basal da intrusão, composta por norito adcumulático; ii. Zona Ultramáfica, caracterizada por dunito e harzburgito e iii. Zona Máfica Superior, predominantemente de composição norito, com porções isoladas de dunito feldspático. O complexo apresenta sequência de cristalização composta por: Olivina + Cromo-Espinélio > Olivina + Ortopiroxênio > Ortopiroxênio + Plagioclásio > Clinopiroxênio. A mineralogia primária das rochas é frequentemente substituída por mineralogia metamórfica, devido ao metamorfismo heterogêneo sobreposto ao Complexo. Apesar da recristalização mineralógica, tal transformação metamórfica muitas vezes preserva as texturas magmáticas. O metamorfismo sobreposto ao complexo atingiu fácies metamórfica anfibolito de alta pressão, marcada pela presença da paragênese cianita-ortoanfibólio-hornblenda-plagioclásio, atingindo pressões de aproximadamente 8.5 kbar e temperaturas de até aproximadamente 750 °C. A mineralização primária de Ni-Cu-EGP sulfetado ocorre em rochas máficas e ultramáficas do complexo, porém a deformação superimposta no complexo pode localmente remobiliza-la. A mineralização é predominantemente do tipo disseminada, tanto nas rochas máficas quanto ultramáficas, porem localmente ocorrem em textura maciça.
Inserted in the context of the Goiás Magmatic Arc, the mafic-ultramafic complex of Mangabal is associated with several neoproterozoic mafic-ultramafic intrusions formed during the Brasiliano Orogeny in the center of Brazil. This study included fieldwork data, systematic drill-core sampling, mineral chemistry and Sm-Nd isotopic geochemistry in order to better understand the petrology of the mafic-ultramafic complex of Mangabal and associated Ni-Cu-PGE mineralization. The Mangabal Complex is inserted in the São Luís dos Montes Belos Shear Zone and is composed of two metamorphosed mafic-ultramafic bodies. The northern limb is approximately 6 km² and is stretched towards E-W; already the south member, distant approximately 2 km of the previous one, is approximately 10km wide by 5.5km long. Both bodies exhibit the same mineralogy, igneous crystallization sequence and mineral chemistry. The stratigraphy of the Mangabal Complex can be divided into three main zones: i. Lower Mafic Zone, located in the basal portion of the intrusion, composed by addcumulatic norite; ii. Ultramafic Zone, characterized by dunite and harzburgite and iii. Upper Mafic Zone, consisting predominantly of norite composition, with isolated portions of feldspathic dunite. The complex has the following crystallization: Olivine + Chromium-Spinel> Olivine + Orthopyroxene> Orthopyroxene + Plagioclase > Clinopyroxene. The primary mineralogy is often replaced due to an overlapping heterogeneous metamorphic transformation. Despite the mineralogical recrystallization, metamorphic transformation often preserves the magmatic textures. The metamorphism superimposed on the complex reached high-pressure amphibolite facies, marked by the presence of kyanite-ortoamphibole-hornblende, reaching pressures of approximately 8.5 kbar and temperatures up to 780 ° C. The primary Ni-Cu-EGP sulfide mineralization occurs in mafic and ultramafic rocks of the complex, but the deformation in the complex can locally remobilize the sulfides and, particularly, nickel and palladium. The mineralization is predominantly disseminated, occurring in both mafic and ultramafic rocks, but massive sulfide levels occur locally, mainly in metamorphic portions.

Abstract:

I dagens samhälle är påtagliga skillnader i hälsa mellan olika sociala klasser ett välkänt faktum. Eftersom arbetet har en central plats i individens liv, är arbetsvillkoren som är direkt kopplade till klass, viktiga för skillnader i hälsa mellan olika yrkesgrupper. Utöver dessa kan en rad andra faktorer som påverkar sambandet mellan klass och hälsa nämnas. Frågan som uppstår och kommer att behandlas i denna undersökning, med hjälp av en regressionsanalys, är hur mycket av sambandet mellan klass och hälsa som kan förklaras med hjälp av yrkesrelaterade faktorer, såsom krav, kontroll och stöd. Vidare är vi intresserade av den relativt outforskade variabeln sjuknärvaro, och om den kan ge någon implikation på vårt samband. Separata regressionsanalyser för respektive kön kommer att genomföras för att undersöka om sambandet mellan klass och hälsa skiljer sig mellan män och kvinnor. Denna undersökning utgår från LNU-datamaterialet (2000). Resultaten påvisar att det finns ett icke-linjärt samband mellan klass och hälsa. När de yrkesrelaterade variablerna läggs till, blir sambandet mellan klass och hälsa svagare, vilket innebär att krav, kontroll och stöd i arbetet minskar antalet dagar i sjukfrånvaro. När sjuknärvaro läggs till blir sambandet mellan klass och hälsa något svagare för mellantjänstemän, samtidigt som sambandet blir starkare för högre tjänstemän. Kvinnor anger högre sjukfrånvaro jämfört med män. De utvalda variablerna förklarar en relativt liten del av sambandet mellan klass och hälsa, vilket innebär att det finns andra faktorer än arbetsrelaterade villkor och sjuknärvaro som påverkar sambandet.

Abstract:

Utbildning är en viktig del i många människors liv, en del som kan vara avgörande för framtida jobbmöjligheter. Valet att utbilda sig eftergymnasialt eller ej blir därför en viktig milstolpe i den unga elevens liv. Studien syftar till att undersöka hur föräldrarnas ekonomiska- och arbetssituation, utbildningsgrad, samt om de är skilda eller ej, påverkar barnets val att studera på eftergymnasial nivå. För att göra detta används måttet EGP och frågeställningen är: Hur påverkar föräldrarnas EGP, om de har studerat på eftergymnasial nivå samt om de är skilda eller ej, barnets beslut att utbilda sig eftergymnasialt. Baserat på tidigare forskning inom ämnet lyder hypotesen att ju högre föräldrarnas EGP är, ju fler av dem som har eftergymnasial utbildning samt om de lever tillsammans alla är faktorer som innebär en ökad sannolikhet att deras barn ska utbilda sig eftergymnasialt, och tvärtom. För att förklara varför dessa faktorer bidrar till elevens val appliceras socialisationsteori samt nätverksteori. Genom att använda datamaterial från Levnadsnivåundersökningen 2010, skapas regressionsanalyser för att se hur de oberoende variablerna påverkar sannolikheten att studera eftergymnasialt. Resultatet visar att hög EGP, att föräldrarna har studerat eftergymnasialt samt att de lever ihop alla ökar sannolikheten för att deras barn ska välja att utbilda sig eftergymnasialt. Detta överensstämmer med tidigare forskning och kan förstås utifrån studiens teorier om hur beteenden reproduceras från en generation till nästa.

Abstract:

Cytoplasmic mRNA-containing granules in eukaryotic cells play key roles inthe storage, localisation and degradation of mRNA. In yeast, depletion of glucoseleads to the rapid inhibition of translation initiation and consequent appearance of Pbodiesand EGP-bodies. P-bodies contain factors of the mRNA decay pathway andtherefore, are likely to be sites in which mRNAs targeted for degradation arelocalised. In contrast, EGP-bodies lack decay components and contain onlytranslation initiation factors and RNA binding proteins. Thus EGP-bodies have beensuggested to be storage repositories for mRNAs that need to be rapidly translatedfollowing glucose readdition. In this study we utilised the m-TAG system to investigate the localisation ofendogenous MS2-tagged mRNAs with P-bodies and EGP-bodies. A triplefluorescent labelled system developed show that a class of unregulated mRNAslocalised into P-bodies following glucose starvation. It was also observed that thesespecific abundant classes of mRNAs can be found in aggregates prior to any cellularstress and upon glucose starvation these aggregates coalesce into larger granules thatcolocalise with P-body components. This coalescence of mRNA aggregatesfollowing glucose starvation does not rely upon the recruitment of mRNA decayfactors and appears to precede this event. Indeed mRNAs in mutants deficient in Pbodyformation still develop large aggregates following glucose stress. In unstressedcells it appears that the mRNA granules are implicated in high-level translation ofthese specific abundant mRNAs. Following the inhibition of translation initiation inresponse to stress, these granules nucleate P-body formation via aggregation and therecruitment of mRNA decay factors.

Resumo: Este trabalho objetivou avaliar. por meio de um estudo da literatura. o potencial da Província Ígnea do Paraná - SE da América do Sul - para depósitos magmáticos de sulfetos de Ni-Cu-EGP. A proposta é baseada na presença das mineralizações desse tipo em Noril'sk - Talnakh na Província de CFB dos Traps Siberianos. Rússia; e no Complexo Insizwa (Waterfall Gorge) na Província Ígnea do Karro. Transkei - África do Sul. A literatura sobre o contexto geológico dessas duas mineralizações. tomadas como modelos para defmir critérios de avaliação da Província do Paraná. mostra que ambas se desenvolveram sob condicionamentos geológicos (metalotectos) bastante semelhantes. subdivididos em dois tipos: regionais e locais. Os metalotectos regionais permitem reconhecer dentro das províncias de CFB o contexto geodinâmico regional favorável para a ocorrência de mineralizações. mostrando que estes depósitos estão particularmente associados: (1) às fases iniciais de magmatismo nas províncias de CFB; (2) aos estágios primordiais do desenvolvimento de estruturas de rifteamento continental; (3) a locais da província que evoluíram relacionados a regiões do manto anomalamente quentes (plumas I hot spots) produzindo uma grande diversidade de tipos litológicos; e (4) a falhas antigas do embasamento reativadas. Os metalotectos locais mostram as mineralizaçõe8 associadas a várias feições. tais como: (5) ao magmatismo tholeiítico de baixo-Ti; (6) à porção basal de corpos diferenciados. acamadados; (7) à magmas empobrecidos em elementos calc6filos (Ni. Cu. EGP); e (8) processos relacionadas à segregação de sulfetos. do tipo assimilação crostal (enriquecimento em elementos litóftlos incompatíveis) e injeções múltiplas (fracionamento invertido). Estes metalotectos. tanto os regionais como os locais se caracterizam pelo seu caráter genérico. podendo ser utilizados para avaliação de qualquer província de CFB. Na província ígnea do Paraná. a aplicação dos metalotectos regionais aponta a sua borda leste. cujo desenvolvimento esteve mais diretamente vinculado à evolução do Rift Sul-Atlântico. como o contexto regional favorável para a ocorrência de possíveis mineralizações de Ni-Cu-EGP. Este contexto da borda leste da província. analisado sob a ótica dos metalotectos locais. revela uma potencialidade relativa decrescente de sul para norte e define. ainda. o Complexo Básico de Lomba Grande (Gravataf - RS). na porção sul de baixo- Ti da província. como um alvo merecedor de investigação detalhada.
Abstract: This dissertation presents a literature review of the potential for Ni-Cu-PGE mineralisations in the Paraná igneous province of Southeastem South America. The work was based 0Il the presence of mineralised bodies at Noril' sk- Ta1nakh (Russia) and Insizwa- Waterfall Gorge (franskei-Republic of South Africa) respectively in the Siberian and Karoo CfB provinces. The geologic settings of mineralisation at Noril'sk-Talnakh and Insizwa-Waterfall Gorge arevery similar and may be grouped in regional and local metalotects. On a regional scale, it is suggested that the mineralisations are associated (1) with tbe initial magmatism of any particular CfB province; (2) with the early development of continental rifting structures; (3) with old reactivated basement faults; (4) with regions of mantle anomalously hot (mande plumes orhot-spot). hence resulting in a diversity of rock types. The local metalotects indicate that mineralisation is found (5) associated with low-titanium tholeiitic magmatism; (6) in magmas depleted in chalcophile elements (Ni. Cu. PGE); (7) at the basal zone of differentiated layered bodies; and (8) associated with sulphide segregatioo processes such as crostal contamination and multiple injections. Because of their generic nature. the local and regional metallogenic constraints may be applicable to any CfB province worldwide. In South America the regional metalotects indicate that the eastem boundary of the Paraná igneous province is tbe most favourable region for the occurrence of Ni-Cu-PGE mineralisation due to its dose evolution with the South Atlantic rifting. The local criteria show that the metallogenic potential of the eastem boundary of the Paraná igneous province decreases from south to north, and that the Lomba Grande Basic Complexo located in the Gravataí municipality (Rio Grande do Sul State) within the southem low-titanium domain of the province. stands as an area which deserves further studies

The aim of this study was to evaluate the bonding quality of two adhesives (PVA and EPI) in top and side joints of Cupressus lusitanica in production of EGP panels. Anatomical, chemical and physical characterization was performed to determine the influence on the formation and performance of bonded joints. For evaluation of end-grain joints in static bending tests and tension parallel were assessed two adhesives (PVA and EPI), grammage (180 and 200 g/cm²) and two types of end-grain joints (butt-joint and finger-joint). In addition to the strength and stiffness analysis was applied the technique of scanning electron microscopy technique (SEM) to verify the influence of moisture contend in glued bonds of parallel tensile specimens. The side bonding was performed with two adhesive (PVA and EPI) and two grammage (180 and 200 g/m²) by shear test in the central glue line. As result, the specie has low porosity and fine texture; chemical properties was similar to conifers usually used to wood panels production; wood showed low density (0.41g/cm³) with high dimensional stability; for glued end-grain joints, the treatment composed of finger-joint, adhesive EPI with grammage 180 g/m² (T7), showed greater resistance to parallel traction and bending test; SEM analysis allowed the visualization and verification of PVA adhesive degradation by moisture, and demonstrated that EPI adhesive has no structural change in same condition; for side bonding of Cupressus lusitanica timber is indicated using EPI adhesive with grammage 180 g/m² (T3) due to high strength and wood failure percentage
O objetivo do presente estudo foi avaliar a qualidade de colagem de dois adesivos (PVA e EPI) em junções de topo e laterais da madeira de Cupressus lusitanica na produção de painéis EGP. Foi realizada a caracterização anatômica, química e física da madeira da espécie a fim de determinar a influência na formação e desempenho das juntas coladas. Para a avaliação das junções de topo coladas foram avaliados por meio dos ensaio de flexão estática e tração paralela, dois adesivos (PVA e EPI), duas gramaturas (180 e 200 g/m²) e dois tipos de junções de topo (plana e finger-joint). Além da análise de resistência e rigidez, foi aplicada a técnica de microscopia eletrônica de varredura (MEV) para verificar a influência do teor de umidade na qualidade de colagem dos corpos de prova de tração paralela. A colagem lateral foi realizada com dois adesivos (PVA e EPI) e duas gramaturas (180 e 200 g/m²) pelo ensaio de cisalhamento na linha de cola central. Como resultado, a espécie apresenta porosidade reduzida e textura fina; as propriedades químicas foram semelhantes às de coníferas normalmente utilizadas para produção de painéis de madeira; a madeira apresentou baixa massa específica (0,41 g/cm³) com alta estabilidade dimensional; para as juntas de topo coladas, o tratamento composto por junções do tipo finger-joint, adesivo EPI com gramatura de 180 g/m² (T7), apresentou maior resistência para o ensaio de tração paralela e flexão estática; a análise por MEV permitiu a visualização e comprovação da degradação do adesivo PVA por ação da umidade, e demonstrou que o adesivo EPI não apresenta alteração estrutural na mesma condição; e para a colagem lateral da madeira de Cupressus lusitanica é indicado a utilização de adesivo EPI com gramatura de 180 g/m² (T3), devido à elevada resistência e percentual de falha na madeira

O Complexo Máfico-Ultramáfico Acamadado Lago Grande contém mineralização de EGP associada a níveis centimétricos de cromititos e sulfetos. Pertence à Suíte Máfica-Ultramáfica Serra Leste (Ferreira Filho et al., 2007) – região leste da Província Mineral Carajás, cujo principal representante é o Complexo Luanga também mineralizado a EGP. A Suíte Serra Leste situa-se nas imediações de Serra Pelada, importante depósito epigenético de Au-PGE (Grainger et al., 2002). Trata-se de um corpo intrusivo posicionado entre o Complexo Xingu e o Grupo Rio Novo, com estratigrafia magmática composta por estrato ultramáfico harzburgítico na base, seguido de pacote piroxenítico e espessa unidade de gabro no topo. O pacote ultramáfico apresenta textura primária cumulática produzida pela olivina e pelo ortopiroxênio, enquanto que no pacote gabróico a textura cumulática é dada pelo plagioclásio. Resultados de química mineral revelam magma relativamente primitivo - olivina (Fo82,5 a Fo85,7); piroxênio (En82,6 a En85,3); plagioclásio (An67,9 a An45,7). Ocorre cromita sob a forma disseminada e de delgado estrato de cromitito situado no topo do pacote de rochas ultramáficas. O empilhamento estratigráfico revela “trend” de diferenciação normal da base para o topo do Complexo e os dados estruturais sugerem que a câmara magmática esteja invertida. A mineralogia primária das rochas está praticamente toda transformada hidrotermalmente, restando relictos da mineralogia primária. Olivina, opx, cpx e plagioclásio estão transformados em serpentina, hornblenda, Mg-cumingtonita, tremolita, actinolita, talco, saussurita, carbonato, epidoto, clorita e quartzo. Estas condições metamórficas são condizentes com fácies xisto verde a anfibolito. O conteúdo em elementos maiores e menores, bem como elementos traço reflete a percentagem de cumulados de olivina–opx-pl-cromita nas rochas indicando o fracionamento do magma da base para o topo da câmara magmática. Os teores de ETR nas rochas do Complexo Lago Grande apresentam inclinação positiva, sendo suave para as rochas ultramáficas e mais forte para a unidade gabróica, denotando enriquecimento em ETRL e forte anomalia de Eu para as rochas do Complexo Lago Grande. Dosagens em cristais de zircão extraídos de leucogabros pegmatóides retornaram idade por Sm/Nd de 2,72 Ga, com _Nd (T=2.72 Ga) valores (−0.32 a−4.25), indicando contaminação das rochas por elementos das encaixantes. Datações U/Pb indicaram idade de 2.722±53 Ma para cristalização das rochas do Complexo Lago Grande e intersecção com a concórdia em 2.553±61 Ma, sugerindo atuação do processo metassomático hidrotermal IOCG sobre as rochas deste complexo. Há ainda outra intersecção com a concórdia em 600 Ma representado influência do evento Brasiliano sobre estas rochas. Os estudos focando a caracterização de EGP demonstram que nos cromititos predomina alta relação Pt-Pd-Rh e sulfo-arsenietos de Pt e Pd, enquanto que nos níveis sulfetados predomina baixa relação Pt-Pd e bismutet. _______________________________________________________________________________________ ABSTRACT
The Lago Grande and Luanga mafic-ultramafic complexes are part of a cluster of PGEmineralized layered intrusions located in the eastern part of the Carajás Mineral Province (CMP). The CMP occurs in the southeastern portion of the Amazonian Craton and is divided in the Rio Maria Domain to the south, where typical NeoArchean granite-greenstone terrains occur, and the Itacaiúnas Domain to the north. The latter includes the Archean (ca 2.75 Ga) metabasalt sequence of the Grão Pará Group, footwall to the jaspilite-hosted, giant iron deposits of Carajás. The PGE-mineralized intrusions occur in the Itacaiúnas Domain, which is also known for hosting several Cu-Au, Au-PGE and Ni world-class deposits. The Lago Grande Complex is a NE-trending medium-size (12-km-long and average 1.7- km-wide) layered intrusion consisting mainly of mafic cumulate rocks and minor ultramafic cumulates. The stratigraphy of the intrusion is overturned and, to the south, overlain by highly foliated metamorphic rocks of the Xingu Complex. The layered sequence consists of an Ultramafic Zone to the southeast, and a Mafic Zone to the northwest. Geological sections defined by drilling indicate that igneous layers have moderate dip to the SE, such that the Ultramafic Zone overly the Mafic Zone. The Ultramafic Zone, about 4 km long and 500 meter wide, comprises an up to 250 meter-thick sequence of interlayered harzburgite and pyroxenite at the base and pyroxenite at the top. The lower contact of the Ultramafic Zone with the Xingu Complex is poorly exposed, whereas the contact with the overlying Mafic Zone is gradational and characterized by interlayered pyroxenite and gabbroic rocks. The Mafic Zone consists of a monotonous sequence of gabbroic rocks with an estimated thickness of up to 1,000 meters in the central part. Primary igneous minerals of the Lago Grande Complex are partially replaced by metamorphic assemblages that indicate temperatures up to the amphibolite facies of regional metamorphism. This metamorphic alteration is heterogeneous and characterized by an extensive hydration that largely preserves primary textures and bulk chemical composition. The penetrative fabric when present is restricted to narrow domains of up to few meters, and igneous textures are identified in adjacent non-deformed domains. Metamorphic assemblages consist of variable proportions of Mg-cummingtonite, serpentine, talc and magnetite in ultramafic rocks, and hornblende and/or actinolite-tremolite, clinozoizite, chlorite, micas, albite and minor quartz in mafic rocks. The compositional range of cumulus olivine (Fo82.5-85.7) is consistent with a moderately primitive composition for the parental magma of the Lago Grande Complex. Cryptic variation of olivine in the Ultramafic Zone suggests the existence of one major compositional reversal interpreted as resulting of open-system crystallization involving replenishment by new primitive magma pulses. The sequence of crystallization in the Lago Grande Complex, consisting of olivine + chromite, orthopyroxene + chromite, orthopyroxene, orthopyroxene + plagioclase and orthopyroxene + plagioclase + clinopyroxene, suggests that the parental magma was silica saturated. Mantle-normalized alteration-resistant trace element profiles of gabbroic rocks of the Lago Grande Complex are fractionated, as indicated by relative enrichment in LREE and Th, with pronounced negative Nb and Ta anomalies. Nd isotopic data obtained for both mafic and ultramafic lithotypes render Nd model ages between 2.94 and 3.56 Ga, with variably negative _Nd (T=2.72 Ga) values (-0.32 to -4.25). The crystallization sequence of the intrusion and the composition of cumulus minerals, together with lithogeochemical and Nd isotopic results, are consistent with an original mantle melt contaminated with older continental crust. Different styles of PGE mineralization occur in the Lago Grande Complex, as indicated by PGE mineralization associated with sulfide-poor chromitite, sulfide-bearing harzburgite and venulated sulfide-bearing altered rocks. The latter is considered to result from hydrothermal remobilization of the chromitite-hosted and/or sulfide-bearing magmatic mineralization. In sulfide-poor chromitite of the Lago Grande Complex the PPGE are highly enriched and show a negative slope in mantle-normalized profile for PGE contents, whereas IPGE are moderately enriched and show a positive slope. Normalized profile of the chromitite sample from the Lago Grande Complex is generally similar to profiles from Middle Group (MG) and Upper Group (UG) chromitites from the Bushveld Complex, and very close to profiles and overall contents of the MG-4 chromitites. Platinum group minerals (PGM) occur mainly at the edge of chromite crystals in the Lago Grande chromitite, consisting mainly of arsenites and sulfo-arsenites. Sulfidebearing harzburgite samples with well preserved igneous mineralogy of the Lago Grande complex have low Pt/Pd (0.2 to 0.3) and high Pd/Ir (116.7 to 170.0) ratios. These ratios are very distinct from those obtained in the chromitite sample, thus suggesting that PGE contents in sulfide-bearing harzburgites and chromitites result from different magmatic concentration processes. Altered and venulated sulfide-bearing harzburgite samples from the Lago Grande complex have highly variable PGE contents. This variation is indicated by Pt/Pd ratio (< 0.02 to 8.0) and Pd/Ir ratio (5.0 to 810.0), suggesting that PGE were mobile and fractionated during hydrothermal alteration. Preliminary studies of PGM in venulated samples from the Lago Grande complex identified several minerals with variable contents of Cl and Bi. Mineralogical results in venulated and altered sulfide-bearing rocks suggest that Cl-bearing saline hydrothermal fluids, similar to those considered to be associated with the origin of both NeoArchean IOCG deposits and smaller Paleoproterozoic Cu-Au-W-Bi deposits in the Carajás Mineral Province, may be involved in the PGE remobilization by hydrothermal fluids. The 2722±53 Ma U-Pb zircon age determined in this study for the Lago Grande Complex overlaps with the crystallization age of the Luanga Complex. This result supports the interpretation that layered intrusions in the eastern portion of the Carajás region result from coeval magmatic events. Similar styles of magmatic PGE mineralization, including PGE associated with sulfide-poor chromitites and PGE associated with disseminated sulfides in ultramafic cumulates, occur in the coeval Luanga and Lago Grande complexes. PGE profiles for chromitites of the Lago Grande and Luanga complexes are remarkably similar suggesting that the same parental magma and/or magmatic concentration process were involved. The distribution of different styles of magmatic PGE mineralization in these two complexes, as well as in other intrusions located in the eastern portion of the Carajás Mineral Province, support the concept that they belong to a PGE-enriched mafic-ultramafic magma type, designated the Serra Leste Magmatic Suite. These layered complexes crystallized from siliceous high magnesian basaltic magmas, similar to the parental liquids to the world's principal PGE-sulfide deposits, such as those hosted by the Bushveld and Stillwater complexes.

Abstract:

Studier inom sociologi och Total Quality Management (TQM) har visat att anställda som är tillfredsställda i arbetet är mer motiverade att göra ett bra jobb, har god arbetsmoral och arbetar mer effektivt än de som inte är tillfredsställda. Syftet med denna kvantitativt inriktade uppsats var att finna huruvida klassposition på arbetsmarkanden, förtroende för ledningen och möjligheten att få hjälp av sina arbetskamrater är faktorer som förklarar sannolikheten att vara mycket tillfredsställd i sitt arbete. Klassposition definierades enligt klasschemat ”Erikson, Goldthorpe och Portocarero” (EGP) där de som har en tjänsterelation betraktades som högre tjänstemän och mellantjänstemän, de som hade ett blandat kontrakt sågs som lägre tjänstemän och att de som hade ett arbetskontrakt definierades som okvalificerade och kvalificerade arbetare. En logistisk regression genomfördes på det amerikanska datamaterialet General Social Survey (GSS) från år 2010. 2044 individer ingick i datamaterialet varav 916 av dessa ingick i analyserna till följd av ett bortfall på 55 %. Resultaten från denna analys visade att det inte går att statistiskt säkerställa att klassposition har en inverkan på arbetstillfredsställelse, däremot är sannolikheten att vara mycket tillfredsställd i sitt arbete högre bland de individer som har mycket förtroende för sin ledning och de som instämmer att de i mycket hög grad kan få hjälp av sina arbetskamrater. Ytterligare faktorer som visade sig ha en inverkan på arbetstillfredsställelsen är ålder, inkomst och graden av autonomi i individens yrkesutövning. Att nå kunskap om hur relationer till arbetstillfredsställelse ser ut, kan ses som en grundförutsättning för att det ska gå att utföra förändringar i arbetsmiljön med syfte att höja de anställdas trivsel.

Abstract:

The Mafic-Ultramafic Brejo Seco Complex occurs on the western end of the Neoproterozoic Riacho do Pontal fold belt, the northern limit of the São Francisco Craton, State of Piaui, Northeast of Brazil. In this work, cartographic, petrographic, geochemical and isotopic data enabled a new genetic model for the complex and an evaluation of its metallogenetic potential. The Brejo Seco Complex (BSC) consists of a layered igneous body, tectonically inverted, dipping on average 70° to north. It was considered here as intracontinental in origin, in contrast to an ophiolitic origin previously proposed. The stratigraphy of the complex can be divided into four major zones: Lower Mafic Zone (LMZ), Ultramafic Zone (UZ), Mafic Transitional Zone (MTZ) and Upper Mafic Zone (UMZ). Sm-Nd isotopic data indicate that the complex intruded the continental crust at c.a. 900 Ma. The magmatic crystallization sequence (Ol+Chr >> Pl+Ol+Chr >> Pl+Cpx+Ol >> Pl+Cpx+Ilm+Mag+Apt) defined for the BSC, together with geochemical fractionation and olivine chemistry, suggest an affinity for Mg-tholeiitic parental magma. Nd(T=900) values obtained along of Brejo Seco stratigraphy (-0.2 a +3.3), show the interaction of parental magma with sialic crust and together with crystallization sequence and mineral chemistry, record at least four major phases of magmatic chamber filling. The phase three has a special interest as it represents the sulphide mineralization, located in the contact between the UZ and the MTZ, and formed by the interaction between a primitive parental magma (Fo87-89) and contaminated (Nd < 0) and moderately a primitive magma (Fo82). The evaluation of the metallogenic potential of the BSC to host Ni-Cu-(EGP) sulphide deposits revealed no potential target specifically, but can be used as a guide for future exploration works. Chemical analyzes performed on mineralized zone indicated low levels of Ni-Cu-(EGP). The Tonian age (~ 900 Ma) obtained for the CBS allows to interpret it as a record of early rifting stages of the Riacho do Pontal fold belt, as well as correlate it to Monte Orebe basalts (~820 Ma), which represent the oceanic crust developed during the rifting evolution. The BSC can also be correlated to the Tonian extensional magmatic event responsible for fragmentation of the supercontinent Rodinia. Evidence of this magmatism are present in several fold belts as well as the São Francisco and Congo Cratons.
O Complexo máfico-ultramáfico de Brejo Seco ocorre no extremo oeste da Faixa neoproterozóica Riacho do Pontal, limite norte do Cráton do São Francisco, sudeste do Estado do Piauí, Brasil. Neste trabalho, dados cartográficos, petrográficos, geoquímicos e isotópicos possibilitaram um novo modelo para a sua gênese e uma avaliação de seu potencial metalogenético. O Complexo de Brejo Seco (CBS) consiste em um corpo ígneo acamadado, invertido tectonicamente, que mergulha em média 70° para norte. Foi aqui considerado como de origem intracontinental, em contraste a uma origem ofiolítica previamente proposta. Sua estratigrafia é formada por quatro zonas principais: Zona Máfica Inferior (ZMI), Zona Ultramáfica (ZU), Zona Máfica Transicional (ZMT) e Zona Máfica Superior (ZMS). Dados isotópicos Sm-Nd indicam que o CBS intrudiu a crosta continental há aproximadamente 900 Ma. A sequência de cristalização magmática (Ol+Chr >> Pl+Ol+Chr >> Pl+Cpx+Ol >> Pl+Cpx+Ilm+Mag+Apt) definida para o CBS, em conjunto ao fracionamento geoquímico e a química da olivina, sugerem uma afinidade Mg-toleítica para o magma parental. Os valores de åNd(T=900) obtidos ao longo da estratigrafia do CBS (-0.2 a +3.3), evidenciam a interação do magma parental com a crosta siálica e, em conjunto a sequência de cristalização e a química mineral, registram pelo menos quatro estágios principais de preenchimento da câmara magmática. Destaca-se o Estágio III, que representa a mineralização sulfetada localizada nos contatos entre a ZU e ZMT e formada pela interação entre um magma parental primitivo (Fo87-89) e contaminado (åNd < 0), com um magma moderadamente primitivo (Fo82). A avaliação do potencial metalogenético do CBS em hospedar depósitos sulfetados de Ni-Cu- (EGP) não revelou nenhum alvo especificamente em potencial, mas pode ser utilizada como um guia para futuros trabalhos de exploração. Análises químicas realizadas na zona mineralizada indicaram baixos teores de Ni-Cu- (EGP). A idade toniana (~900 Ma) obtida para o CBS permite interpreta-lo como um registro dos estágios iniciais do rifteamento Riacho do Pontal e correlaciona-lo aos basaltos Monte Orebe (~820 Ma), que representam a crosta oceânica desenvolvida com a evolução do rifte. O CBS também pode ser correlacionado ao evento magmático extensional toniano, responsável pela fragmentação do Supercontinente Rodínia. Evidências deste magmatismo estão presentes no Escudo São Franciscano e no Escudo do Congo.

Dans cette thèse, les derniers développements en matière de modélisation moléculaire sont utilisés pour étudier la spectroscopie de molécules contenant de gros ligands. La première partie de ce document présente les méthodes de la chimie quantique utilisées par la suite. La seconde partie est dédiée à l'étude des pseudopotentiels de groupes. Cette étude permet mieux comprendre leur fonctionnement. De plus, certaines faiblesses dans la théorie sont démontrées et plusieurs solutions proposées. La dernière partie est consacrée a l'utilisation des pseudopotentiels de groupes. Pour la première fois, les dix premiers états du composé à valence mixte [Fe2(OH)3(NH3)6]2+ sont obtenus avec précision. Ceci permet d'étudier le phénomène de double échange. Enfin, les premières transitions électroniques des composés M(C8H8)2 (M=Ce, Nd, Tb, Yb, Th, U) sont étudiées. Les résultats obtenus permettent d'apporter des informations sur la structure électronique de l'état fondamental de Ce(C8H8)2

Abstract:

Le complexe mafique–ultramafique lité Yacouba est intrusif au sein des granulites gneissiques du domaine archéen de Man (3,6-2,78 Ga) dans la région de Biankouma-Sipilou (ouest de la Côte d'Ivoire). Dans le secteur de Samapleu, il est composé de trois entités ; dépôt principal de Samapleu (SM), l’Extension 1 de Samapleu (E1) et l’occurrence de Yorodougou (Yo). Il comprend des horizons de webstérites, péridotites, chromitites, norites, gabbro-norites. Ces horizons (épaisseur cumulée de 80 à 200 m) sont inclinés de 70 à 80° vers le SE ; présentent une zonation concentrique, qui sont autant de caractéristiques d’un dyke ; un enracinement à plus de 600 m à partir de la surface avec une jonction des intrusions (SM, E1) plus en profondeur. Les contacts avec l’encaissant gneissique (localement site E1) sont marqués par une zone hybride (condition P = 7,5±1Kbar et T = 850°C ± 100°C) interprétées comme le résultat d'un métamorphisme de contact lors de la mise en place de l’intrusion en base de croûte à environ 22 km de profondeur. Les gneiss et granulites du socle, tout comme les faciès de la zone hybride, préservent des âges archéens (~2,78 Ga, U-Pb sur zircon). Des cristaux de rutile observés dans la zone hybride révèlent un âge U-Pb de 2,09 Ga interprété comme l'âge du métamorphisme de contact et donc de la mise en place de l'intrusion.La minéralisation en Ni-Cu (essentiellement disséminée avec des veines sulfurées subverticales semi-massives à massives) est composée de pentlandite, chalcopyrite, pyrrhotite, rarement pyrite. La texture des sulfures varie de matricielle, en filets, en gouttelettes, ou brèchique. Les réserves estimées des dépôts de Samapleu (SM et E1) font plus de 40 millions de tonnes à une teneur moyenne de 0,25% Ni et 0,22% Cu dans la partie supérieure des intrusions (Sama Nickel-CI, Août 2013). Des MGP riches en palladium (Pd) sont associés aux sulfures et plusieurs bandelettes de chromite sont également présentes. Ces observations suggèrent un liquide sulfuré immiscible formé à partir du liquide silicaté initial consécutivement à la saturation en soufre du système. Ces sulfures d’origine essentiellement mantellique ont été probablement formés par injection de plusieurs magmas. Cependant une partie de ces sulfures aurait pu se former par l’assimilation des roches granulitiques encaissantes.La composition du liquide parent révèle une composition de basalte à forte teneur en MgO et faible teneur en Ti et suggère que les intrusions de Samapleu se sont formées par fusion du manteau supérieur sous l’influence d'un panache mantellique. Ainsi, lors de leurs remontées, le magma a assimilé les roches granulites encaissantes environnantes
The Yacouba layered complex intrudes the archean (3.6-2.78 Ga) Man field in the Biankouma-Sipilou area, western Ivory Coast. In Samapleu area, the complex is composed of three entities; Samapleu Main (SM); Samapleu Extension 1 (E1) and Yorodougou (Yo). It includes websterites, peridotites, chromitites, norites, gabbro-norites horizons. These horizons (total thickness of 80 to 200 m) inclined at 70-80° to the SE; arranged symmetrically with mafic layers at the center and ultramafic layers at both margins, are features of a dyke ; show a root more than 600 m from the surface with a junction intrusion (SM, E1) in more depth.At the E1 site, contacts of intrusions with the country rock gneiss are characterized by a hybrid zone (condition P = 7.5±1Kbar and T = 850°C ± 100°C) attributed to contact metamorphism during intrusion of the complex in the lower crust at a depth of about 22 km. Zircons in country rock gneisses and granulites, as well as in the hybrid facies, yield archean ages of ~ 2.78 Ga. Rutiles in the hybrid zone give a U-Pb age of 2.09 Ga, which is interpreted as the age of contact metamorphism and emplacement of the intrusion.The Ni-Cu mineralization (disseminated mainly with subvertical and semi-massive to massive sulfide veins) is composed of pentlandite, chalcopyrite, pyrrhotite and rare pyrite. The SM and E1 sites contain Ni and Cu sulfide deposit with reserves estimated as more than 40 million tons grading 0.25% Ni and 0.22% Cu in the upper portion (Sama Nickel-CI, August 2013). The sulfide textures range from matrix ore, net-textured, droplets or breccia textures. Zones enriched in PGM, particularly Pd, are associated with the sulfides and several chromite bands are also present. These observations suggest that an immiscible sulfide liquid formed from a parental silicate liquid and percolated through the crystal pile. These sulfides mainly mantle origin were probably formed by injecting several magmas. However few of these sulfides may have formed by the assimilation of country rocks.The parental melt composition has a basalt rich MgO and low Ti and suggest Samapleu intrusions were formed by melting of the upper mantle under the influence of a mantle plume. Thus, during its ascent, magma has assimilated the granulites country rocks

Abstract:

Os chapéus de ferro associados ao depósito de Canoas mineralizado em Zn-Pb, em Adrianópolis (PR) e ao depósito de O\'Toole mineralizado em Ni-Cu, em Fortaleza de Minas (MG), contém concentrações anômalas desses metais base. O intemperismo químico do minério sulfetado produziu uma série de feições mineralógicas e geoquímicas características que são diagnóstico para a prospecção mineral e identificação do tipo de depósito mineral. Análises por espectrometria de raios X para elementos maiores e traços, difratometria de raios X, espectroscopia Mössbauer, análises microssituadas, foram utilizadas para este estudo. No depósito de Canoas existem três ocorrências de chapéus de ferro, Canoas 1, Salvador 1 e Salvador 2, os quais apresentam diferenças nos teores de metais base dosados que pode estar relacionado ao tipo de minério e maturidade do chapéu de ferro. O chapéu de ferro de Canoas 1 ocorre sobre o minério primário e assemelha-se a uma zona de sulfato-carbonato. Os chapéus de ferro de Salvador 1 e Salvador 2 apresentam feições e mineralogia características de chapéus de ferro maduros. A associação jarosita-goethita e em menor proporção hematita é a principal feição mineralógica dos chapéus de ferro de Canoas. As jarositas são uma fase transitória e armadilhas para o Pb. No depósito de O\'Toole o intemperismo e alteração supérgena dos sulfetos primários de Ni-Cu evoluíram para uma zona de pentlandita-violarita ou zona de cimentação ou transição. O chapéu de ferro ocorre sobre a zona de transição e tem feições, texturas e mineralogia típicas de um chapéu de ferro maduro e evoluído. Durante os processos de lixiviação dos sulfetos, metais tais como Pb, Zn, Cu, Ni e Co são dissolvidos e podem ser co-precipitados com compostos de Fe ou serem adsorvidos em duas superfícies. No primeiro caso eles são incorporados na estrutura dos minerais de Fe por substituição isomórfica, causando distorções nas dimensões da cela (continua) (dependendo) unitária, dependendo das diferenças entre os raios iônicos. No chapéu de ferro de Canoas a incorporação de Pb e Zn na estrutura da goethita não ficou claramente demonstrada. Para as amostras de chapéu de ferro de O\'Toole as análises sugerem que o Cu e Ni foram incorporados estruturalmente na goethita.
Gossans associated with the Canoas zinc-lead ore deposits, in Adranópolis (PR), and O\'Toole nickel-copper ore deposit, in Fortaleza de Minas (MG), contain anomalous concentrations of these base metal. The chemical weathering of sulfide lodes has produced a series of characteristic mineralogical and geochemical features that are diagnostic for mineral prospection and identification of ore body type. X-ray spectrumetrie analysis of major and trace elements, difractrometry of the X-ray, Mössbauer spectroscopy, microprobe analysis, were used in this study. In the Canoas deposit there are three gossan occurrences, Canoas 1, Salvador 1 and Salvador 2, which have differences in accumulation that may be related to the ore type and gossan maturity. The Canoas 1 gossan is over the primary ore and appears to be a sulphate-carbonate zone. The Salvador 1 and Salvador 2 gossans presented features and mineralogy that are characteristics of the mature gossans. The jarosite-goethite association and to a lesser extent hematite is the principal mineralogical feature of the Canoas gossans. The jarosites are the transitory Pb-bearing phases. In the O\'Toole deposit the weathering and supergene alteration of primary nickel-cooper sulphides evolved to the pentiandite-violarite zone or cementation zone. The gossans is over the cementation zone and has features, textures and mineralogy typical of mature evolved gossans. During the sulphide leaching processes, metals such as Pb, Zn, Cu, Ni and Co are dissolved and can either co-precipitate with Fe compounds or be adsorbed onto their surfaces. In the first case they are incorporated into the Fe-mineral structurs by isomorphous substitution, causing distortions in the unit-cell dimensions, depending on the ionic radii differences. In the Canoas gossan incorporation of the Pb and Zn into the goethite structure are not clearly demonstrated. For the O\'Toole gossan samples the analysis suggests that Cu and Ni structurally incorporated in the goethite lattice.

Abstract:

In recent years EFL education within Saudi Arabia has come under increased scrutiny, due to government efforts to reform the broader education system within the country, and the perceived importance of English as a global language of commerce and enterprise. EFL education within Saudi Arabia suffers from a number of problems, including low standards and a tendency within the Saudi education system to rely upon prescriptive and authoritarian teaching paradigms. In addition to this, there is no cohesive national strategy for EFL teacher training and education, and little emphasis on professional development opportunities for teachers within the EFL field. This study focuses attention on EFL teacher quality within Saudi Arabia as a critical component in improving English language education across the country. The study presents a case study of Umm al-Qura University, in Mecca, Saudi Arabia, in which the perspectives of students, teachers and managers were explored in depth in order to shed light on the current mechanisms for ensuring teaching quality in EFL. Adopting a mixed-methods approach, the study engaged in an in-depth case study of the English Language Centre (ELC) at the Umm al-Qura University. A quantitative questionnaire was distributed to students within the ELC, and semi-structured interviews were undertaken with teachers and academic managers, in addition to classroom observations conducted by the researcher. The findings corroborated recent research on educational paradigms within Saudi Arabia, and highlighted a number of cultural factors that impacted upon teacher quality within the ELC. The findings of the study form the basis of a series of recommendations for improving English language teaching quality within the Kingdom of Saudi Arabia.

This thesis aims to report the results of a study to check the use of project management practices, based on the PMBOK (Project Management Body of Knowledge) Guide, in the day-to-day by project professionals in Brazilian organizations. The effective and efficient implementation of a project requires a composition of knowledge, skills, techniques and tools that are used and defined in many project management guides. This composition is what we call as project management. This study about the degree of use of the practices consisted in a quantitative field survey with the individuals working with project management in their companies. Thus we identified the characteristics of professional, of your organization, the use of practices, and metrics of success of the project. It is emphasized that this research study is limited to Brazilian audience. To achieve the study goals, is was developed as: descriptive analysis, where we seek to describe the reality of project management presented by professionals; explanatory, aiming at clarifying the degree of utilization of these practices in relation to the PMBOK Guide in organizations; and exploratory, as there was little knowledge accumulated and systematized in this area in Brazil . We also use the literature review to consolidate the study of theories relating to the area of project management based on guides , periodicals and journals , academic papers and books on the subject matter. Through the quantitative analysis we sought the compliance of the data collected to allow the logical analysis of information in the process of searching for answers about the evaluation of the PMBOK Guide’s project management principles use degree by project professional in the Brazilian market. The results showed different use degrees of practices according to the nine knowledge areas of the PMBOK Guide and intriguing revelations when analyzed under perspectives like an existence of a PMO (project management office) in the company, project success and among others revealing that the context where the professionals and their organizations can contribute for a significant changing in the use degrees analyzed. This study aims to serve as factor for prospecting of others studies in the area of project management, promoting Brazilian scientific publications.
Esta dissertação de mestrado tem por objetivo relatar o resultado de um estudo de verificação das práticas de gerenciamento de projetos, baseadas no Guia PMBOK (Project Management Body of Knowledge), presentes no dia-a-dia pelos profissionais de projetos das organizações brasileiras. A execução eficaz, eficiente e efetiva de um projeto necessita de uma composição entre conhecimentos, habilidades, técnicas e ferramentas definidos em diversos guias de gestão de projetos. Essa composição é o que se denomina: gerenciamento de projetos. A fundamentação prática aqui apresentada baseou-se em uma pesquisa de campo quantitativa, que inquiriu sujeitos organizacionais atuantes em gestão de projetos em suas empresas. Assim, pôde-se verificar as características do profissional, de sua organização, do uso das práticas e das métricas de sucesso do projeto. Ressalte-se que este estudo limita-se ao Brasil, como ambiente em que atua o público-alvo de pesquisa. Para tanto, o estudo foi desenvolvido: de forma descritiva, a partir da realidade de gestão de projetos apresentada pelos profissionais; explicativa, tendo como objetivo central esclarecer qual o seu grau de utilização em relação ao Guia PMBOK, no contexto das organizações brasileiras; e exploratória, dado que existia pouco conhecimento acumulado e sistematizado a respeito deste tema, na área Brasil. A revisão bibliográfica, para consolidar o estudo das teorias referentes à área gestão de projetos, deu-se por meio de guias, periódicos e jornais especializados, trabalhos acadêmicos e livros sobre o tema em questão e demais textos virtuais. Da análise quantitativa, buscou-se a conformidade sobre os dados coletados a fim de se consolidar a consistência lógica das informações obtidas nas respostas sobre a avaliação do grau de uso do preceitos de gerenciamento de projetos do Guia PMBOK por parte dos profissionais de projetos, do mercado brasileiro. Os resultados demonstraram diferentes graus de uso das práticas relativas às nove áreas de conhecimento do Guia PMBOK. Pôde-se apurar, também, revelações intrigantes como a existência de um EGP (escritório de gestão de projetos) na empresa, como no contexto, no qual estão inseridos os profissionais e suas organizações, podem contribuir de modo significativo tanto na alteração dos graus de uso como no sucesso do projeto. Almeja-se que o presente estudo possa servir de elemento prospectivo para outras pesquisas na área de gerenciamento de projetos, fomentando a realização de trabalhos e publicações científicas, de âmbito brasileiro.

Abstract:

The Australian magpie (Gymnorhina tibicen) is a large, sedentary, omnivorous passerine. In some populations, individuals live in groups, and some of these groups breed cooperatively. The white-backed magpie (G. t. tyrannica) from the south-eastern corner of the continent, has had relatively little study, and few details are known of its mating system, social structure, and method of parental care. I conducted an observational study on a population of white-backed magpies, recording details of their demography, dispersal, breeding system, and parental care. In conjunction, I conducted a genetic analysis of the population, to determine if the genetic mating system matched the observed social system, to detect instances of extra-group mating, and to sex juvenile birds. Extra-pair paternity (EPP) is a common feature of the mating systems of many birds. The rate of EPP may vary between species, races and populations. I made a comparison of extra-group paternity (EGP) rates between two races of the Australian magpie, to determine if similar mating systems were being employed. The two populations had similar social structure, but differed in group size and dispersal. I predicted that dispersal differences would have a profound effect on the rate of EGP between the populations, as the population with the lower rate of dispersal and higher chance of breeding with a close relative would engage in EGPs more frequently. Eight microsatellite loci were used to determine parentage in the white-backed Australian magpie. The rate of EGP was found to be 44%. Dispersal rates were estimated from observational data. Over half of the juvenile magpie cohort from the previous breeding season leave the territorial group. These results contrast sharply with the results found by other researchers in a population of western Australian magpies (G t. dorsalis). In this population, 82% EGP is recorded and dispersal of juveniles is close to nil. The results indicate that dispersal rate is a potentially important predictor of rates of extra-group fertilisations between populations of this species, and suggest that females maximise their reproductive output by avoiding breeding with close kin. The reproductive success of a male bird is often correlated with measurable traits that predict his intrinsic quality. Females are thought to select mates based on their quality to gain their 'good genes'. Male Australian magpies of the white-backed race were trapped in two breeding seasons. Measurements were taken of morphometric and other characteristics in order to discover whether particular traits of males were associated with: a) number of fledglings produced in the territory per season; b) percentage of offspring sired in the territory; and c) whether females select males for their 'good genes'. The only variable that was correlated with number of territorial offspring was feather lice load. Males with high numbers of lice were less likely to produce territorial fledglings in one season and across both seasons. Males of inferior quality may be subject to increased conspecific territorial intrusions, leading to more time spent on defence, more failed breeding attempts, less time allocated to grooming and thus high parasite loads. Males that produced many territorial fledglings were more likely to gain genetic paternity of at least some of them, although again this was significant for only one season. Also, across both seasons, a high number of females in the group was correlated with increased paternity within the group. The general lack of correlation between the variables and level of genetic paternity may be due to females engaging in extra-group mating primarily to avoid breeding with a close relative rather than to choose a quality male. In this scenario, males would not have to be 'high quality', but merely genetically different to the female's social mate. Extra-group paternity (EGP) can affect paternal effort. It may also influence the helping effort of auxiliary birds in cooperatively breeding species. If helping is driven by kin selection, helpers should decline to provision unrelated young. Relatedness becomes difficult to assess however, when females mate outside the group. Alternative rewards may then become important in helper decisions. In my study population of Australian magpies, 38% of fledglings were sired by males outside the territorial group. In a second population (G. t. dorsalis), 82% of fledglings were sired by extra-group males. I observed within-group male and helper feeding effort over three breeding seasons in the first population and obtained data recorded over a single season in the second population. In both populations, males provisioned young regardless of relatedness, as did helpers. Males provisioned less than the nesting female on average. Paternal effort did not reduce with an increase in the rate of EGP between populations. In the population with intermediate levels of EGP, the white-backed magpies, I observed helpers in about half of the sampled territories that produced fledglings. Helpers did not increase the production of young. In the population with high levels of EGP, western magpies, I detected helping behaviour in proportionally more territories. It appears that Australian magpie helpers provide help in order to pay 'rent' and remain on the natal territory. I discuss these results in light of the differences between the two races of magpie and the major theories regarding male parenting decisions and helper activity. Finally, I examine the relatively high rates of EGP's in the Australian magpie from a phylogenetic perspective. Although inbreeding avoidance is strongly supported by this study as the major reason EGP is so common in magpie populations, there may be an element of phylogenetic inertia that maintains the frequency of this behavioural trait. I comment upon the use of single-population estimates of species EGP rates in comparative analyses, given the intraspecific variation discovered between Australian magpie populations. Future directions for the study of mate choice in the Australian magpie are outlined with a proposal to study variation at the major histocompatibility complex between mated pairs.

Notre travail de these a consiste a identifier les proteines codees par les clones eg2 et eg3. Ces adnc correspondent a des arnm specifiquement desadenyles apres la fecondation chez le xenope. Le sequencage de ces deux adnc nous a permis de constater que les sequences qui en sont deduites presentent l'ensemble des motifs caracteristiques retrouve dans les sous-domaines du domaine catalytique des proteines kinases. L'analyse de la sequence des sous-domaines 6b et 8 nous permet de supposer que ces molecules seraient potentiellement des serine/threonine-kinases. L'interrogation des banques de donnees proteiques nous a permis de constater que la sequence du domaine catalytique de la proteine eg2 presentait la similitude la plus elevee avec le domaine catalytique de l'une des sous-unites catalytiques de la proteine kinase a identifiee chez s. Cerevisiae. Pour eg3, le domaine catalytique presente un pourcentage de similitude superieur a 50% avec la sequence du domaine catalytique de la proteine kinase bkin2 identifiee chez h. Vulgare. Dans cette derniere, le domaine catalytique est excentre du cote de l'extremite nh2 de la molecule ce qui correspond a une position peu frequente dans la famille des serine/threonine kinases. Nous avons mis en evidence deux adnc (eg2a et eg2b) codant pour des proteines dont l'identite est de 94,4%. Nous avons prepare un serum polyclonal dirige contre une region specifique de la proteine eg2. Ce dernier nous a permis de constater que la proteine est presente des le debut de l'ovogenese et subsiste au moins jusqu'au stade bourgeon caudal. De plus, nous avons montre que la proteine eg2 est majoritairement synthetisee pendant la maturation ovocytaire. Ceci est en correlation avec la polyadenylation de l'arnm qui a lieu au cours de cette meme phase de l'ovogenese. La proteine est localisee au niveau des poles du fuseau mitotique

Abstract:

Dengue Fever virus (DENV) is a very old mosquito-borne flavivirus that has made a modern worldwide re-emergence as a result of population movement and growth, urbanisation and lapse of vector control. The World Health Organisation estimates that 2.5 billion people, or two-fifths of the world’s population are at risk from DENV, which can cause serious illness and in its severe forms, death. Despite the humanitarian and economic burden that DENV and its flaviviral relatives create, there are no chemotherapeutic drugs available and vaccine development is challenging. Mammalian host cell infection by DENV is mediated by the Envelope glycoprotein (EGP), which covers the entire exposed surface of the mature virus particle and is comprised of three exposed protein domains (DI, DII and DIII) and a transmembrane anchor. While significant effort has been invested to better understand how DIII of EGP participates in receptor mediated endocytosis of DENV into host cells, including the site and structure of the receptor binding site, or carbohydrate recognition domain (CRD), and the structure of ligands involved remain undefined. A recent study of mammalian cell surface glycans involved in DENV infection by Dr Kazuya Hidari and co-workers identified DENV inhibition by the glycolipid Paragloboside, which includes the tetrasaccharide Lacto-N-neotetraose (nLc4)1. This thesis reports an investigation of DENV-2 EGP DIII ligand specificity and characterisation of the DIII CRD involved in mammalian cell infection. To achieve this, soluble and high level expression of DENV-2 ThNH-7/93 EGP DIII was established from Pichia pastoris (P. pastoris) yeast and the recombinant DIII was successfully purified to near homogeneity by single step affinity chromatography. The biological activity of DIII was assessed by DENV permissible cell based assays and the recombinant protein was shown to have retained its wildtype host cell receptor binding activity. Recombinant DIII protein was utilised to successfully establish glycan microarray and saturation transfer difference nuclear magnetic resonance (STD NMR) methodologies, Confidential – not to be copied ii which are useful in the study of EGP ligand specificity. Investigation of nLc4 ligand binding to EGP confirmed that this tetrasaccharide binds to the CRD DIII, involving each of its carbohydrate moieties. Epitope mapping by STD NMR spectroscopy also revealed that the H-1 proton of the N-acetyl-D-glucosamine (GlcNAc) makes closest contact with DIII via its N-acetyl group. Screening of carbohydrate libraries with DENV-2 and a multivalent DIII complex identified additional EGP specificity to several novel binding ligands that share a GlcNAc moiety at the first or second non-reducing cytoplasmexposed positions.

Abstract:

Le platine (Pt), le palladium (Pd) et le rhodium (Rh), font partie des Eléments du Groupe du Platine (EGP), utilisés dans les catalyseurs automobiles. En raison de leur émission dans l'environnement, ces éléments peuvent aujourd'hui être considérés comme des contaminants émergeants et traceurs de la contamination automobile. Cette étude porte sur la dispersion des EGP depuis leur source (monolithes et émission à l'échappement) jusqu'au champ proche (atmosphère, poussières de chaussées, eaux de ruissellement, sédiment,sol de bord de route). Leur mobilité à partir de monolithes a été étudiée en présence d'eau de ruissellement et de molécules organiques. Leur spéciation a été évaluée dans les poussières de chaussées et les sédiments. Les teneurs en EGP dans les monolithes étudiés montrent le remplacement de Pt par Pd dans les catalyseurs récents. L'abondance relative des EGP dans les échantillons environnementaux est Pd > Pt > Rh. Les expérimentations de mobilisation montrent que la mobilisation des EGP est plus significative au contact des molécules organiques, est dépendante du pH de la solution et augmente avec l'âge du monolithe. Rh est l'élément le plus mobilisable dans les monolithes. La spéciation montre que les EGP sont peu mobiles. Dans la part mobilisable, ils sont majoritairement liés à la fraction dite organique
Platinum (Pt), palladium (Pd) and rhodium (Rh) (platinum-group elements; PGEs),are used in automotive catalytic converters to remove harmful emissions from exhaust gas. Nevertheless, nowadays, the PGEs are emerging as new environmental emission contaminators due to their increasing use. The goal of this research is to study the distribution of PGEs from the source (i.e. automotive catalytic converters and exhaust gas) to the environmental samples (i.e. atmospheric particles, road dust,storm water, pond sediments, and road-side soil). The mobility of PGEs from the converters in contact with run off water and natural complexing agents were studied. Also, the speciation of PGEs was investigated in road dust and pond sediments. Comparison of PGE contents in different catalysts confirms the replacement of Pt by Pd in more recent converters. Besides, the relative abundance of PGEs in environmental samples shows higher concentration of Pd compared toPt and Rh (i.e. Pd>Pt>Rh). The results of testing PGEs mobilization in catalytic converters demonstrate more significant mobilization by organic molecules as compared to run off water. Our results also show the dependency of PGEs mobilization on pH and on catalyst age. Among the PGEs, Rh was the most mobilized element in catalytic converters. More importantly, the speciation test shows that while PGEs are low mobile elements, in the mobilizable fraction, PGEs are in the organic fraction

Os Escritórios de Gerenciamento de Projetos (EGPs) têm um papel cada vez mais relevante nas organizações, contribuindo para o sucesso dos projetos, no interesse dos objetivos organizacionais. A atuação dos EGPs, entrementes, transcorre repleta de percalços e desafios, que ocorrem desde a sua implantação nas organizações, percorrendo todo o seu ciclo de vida. Nas organizações públicas, alguns projetos apresentam uma complexa rede relacional, que afeta um grande número de stakeholders, em razão de sua exposição ao escrutínio público, tornando bastante difícil a coordenação e gestão de todos esses atores, o que pode afetar o sucesso dos projetos. Dessa forma, este estudo se propõe a responder ao seguinte problema de pesquisa: quais os principais desafios da implantação e maturação de escritórios de projetos em organizações do governo brasileiro? Para esse fim, foi realizada uma pesquisa qualitativa, com estudos de casos múltiplos, aplicada a dez representantes de oito organizações do governo brasileiro, por meio de entrevistas semiestruturadas. A partir dos resultados encontrados na pesquisa, foram identificados os códigos Burocracia, Capacitação, Comunicação, Cultura da Organização, Dedicação Parcial aos Projetos, Estrutura da Organização, Ferramentas de Gerenciamento de Projetos, Legislação e Política, que representam os principais desafios enfrentados pelos escritórios de gerenciamento de projetos estudados. O entendimento da dinâmica relacional desses códigos contribuiu para uma melhor compreensão dos EGPs das organizações do setor público brasileiro e seus desafios.

Abstract:

This thesis explores the nature of the ego, drawing upon Christian and secular conceptions, in order to determine whether it is something to be affirmed or denied. Contemporary perspectives which either overvalue the individual self, or retort by refuting it, are questioned in the light of psychology, spirituality and Christian doctrine. I have been vexed by the existence of two seemingly opposing views within Christian popular culture. Those who look to the mystical tradition, the Spirituality of the Desert, claim that self-denial is the path to spiritual enlightenment and discovery of the true self; the ego is a false self. By contrast, the world of psychology endorses the merits of a healthy ego. Accordingly, psychology has made a significant contribution to pastoral theology and the life of church communities, especially in relation to personality dynamics. I seek to overcome this dichotomy through a broadening of our understanding of the self and adoption of the notion of personhood arising from a theological anthropology, which includes a relational understanding of imago Dei, Christological kenosis and the social doctrine of the Trinity. Findings are related to the paradoxical demand of Christian discipleship, encapsulated by Jesus’ teaching that his followers must lose themselves in order to be save themselves. The thesis concludes with a more practical turn, applying the insights of the earlier psychology and spirituality chapters, to assess tools for daily life for enhancing emotional and spiritual intelligence, which are taken as interdependent. The goal is for the ego to become servant, not master. The overall approach is a theoretical interdisciplinary one, drawing on the perspectives of philosophy, sociology, psychology, spirituality and theology, in order to gain a comprehensive picture of the ego.

O Modelo Estrutura, Conduta e Performance - Social (ECP-Social) foi construido como alternativa para a avaliação da performance social empresarial. O framework do modelo ECP-Social considera que a pressão exercida pela estrutura de mercado sobre as empresas faz com que elas ajam ou reajam adotando determinado comportamento social, o que promove a performance social. A definição dos indicadores de estrutura de mercado foram baseados no modelo ECP de Scherer e Ross (1990). A partir deste modelo foram feitas adaptações e inclusões para se desenhar a estrutura social do mercado, considerando as características econômicas dele. Já, os indicadores de conduta social fazem referência às funções gerenciais tendo sido estabelecidos indicadores sociais para as funções de administração geral, marketing e comunicação, gestão da cadeia logística, pesquisa e desenvolvimento, manufatura, meio ambiente, finanças, gestão de pessoas, assuntos políticos e assuntos jurídicos. Por fim, os indicadores de performance social apontam os reflexos dos comportamentos empresariais e da pressão sobre a estrutura da indústria através dos impactos sobre os a. & i. internos e externos. Para tornar operazionalizável o framework do modelo ECP-Social foi criada uma ferramenta que permite determinar o nível de conduta social em cada uma das funções gerenciais da empresa. Esse nível de conduta social é confrontando com a pressão exercida pela estrutura de mercado sobre a empresa, de onde se obtem o perfil social empresarial. O modelo foi testado em indústrias avícolas e calçadistas brasileiras. A partir do uso do modelo ECP- Social e sua ferramenta as empresas podem visualizar as áreas de maior e menor comprometimento social e a partir disso direcionar suas ações para as áreas estratégicas em investimentos sociais.
