This work had to verify the influence of massará, while mortar component, in the process of formation of saltpeter in cementitious plaster walls of buildings. The massará is a ceramic material, texture areno usually found in large volumes argillaceous sediments in Teresina, Piaui State capital, which is associated with the Portland cement mortar form for fixing and finishing in construction. Saltpeter or flowering is a pathology that happens in gypsum wallboard, which invariably reaction between soluble salts present in materials, water and oxygen. This pathology, supposedly credited to massará caused its use to suffer significant reduction in the market of the buildings. Verify this situation with particular scientific rigor is part of the proposal of this work. Grading tests Were performed, consistency limits (LL, LP and IP), determination of potential hydrogen, capacity Exchange (CTC), electrical conductivity (EC), x-ray fluorescence (FRX) and x-ray diffraction (DRX). Massará analysed samples in number six, including sample plastering salitrado presented potential hydrogen medium 5.7 in water and 5.2 on KCl n and electrical conductivity (EC), equal to zero. These results pointed to the affirmative that massará is a material that does not provide salinity content that can be taken into consideration. It is therefore concluded that the material analyzed not competing, at least with respect to the presence of soluble salts, for the formation of saltpeter

As teorias e políticas de desenvolvimento regional sofreram grandes alterações nas duas últimas décadas. Os factores que impulsionam o crescimento económico sustentado já não se relacionam apenas com o capital físico, nem sequer com o capital humano regional. As novas condições de competitividade enfatizam a importância do “capital social”, normas e regras sociais, formais ou informais que promovem a compreensão recíproca e a confiança mútuas entre os agentes da economia da região. Este artigo demonstra a forma como as instituições de uma região se podem organizar em torno dos processos de reestruturação produtiva e encorajar as empresas na região a adoptar normas, expectativas, valores, atitudes e práticas comuns, em suma, uma cultura comum de inovação reforçada pelo processo de aprendizagem social. A acção política dinamizada pela autarquia da Covilhã no projecto ReADAPT, a acção da Associação Nacional dos Industriais de Lanifícios ao promover as condições que sustentam e levam ao aparecimento de redes ou agrupamentos de empresas com actividades relacionadas nas áreas de maior potencial de desenvolvimento da região, e o estabelecimento de relações entre essas redes e as restantes instituições (centros de formação, universidade, sindicatos, etc.) constituem o chamado Sistema Regional de Inovação deste território. Num contexto de depressão económica sectorial e regional, o papel da ANIL e das restantes entidades parceiras assumiu-se como de “animadores e facilitadores” do desenvolvimento. A aprendizagem e a reflexão institucional conseguidas contribuíram também para o que ANIL e as restantes entidades parceiras e o sector público com o qual interagem, tenham adquirido uma nova capacidade de inovação estratégica. Neste contexto, instituições de carácter regional/local assumem-se como um elemento essencial na construção de racionalidades e no condicionamento de comportamentos reflexivos e de cooperação, indicando os caminhos possíveis a seguir aos restantes actores da região. Em suma, as dinâmicas de associação entre actores regionais são um ingrediente fundamental na receita para o desenvolvimento das regiões, no sentido em que podem ajudar outros a ajudar-se na criação de significados, na construção de capacidade para agir e no suporte à construção de redes através das quais os agentes económicos e sociais podem colaborar em benefício comum.

The metropolitan regions of Northeast Brazil are being gradually included in a scenario of international investments, which are motivated by the restructuring of both touristic and real-estate sectors. The new capital, real-estate developers and space configurations that result from this process indicate the need for the creation and implementation of public tools which should, at least, allow the mitigation of the urban impacts and environmental losses resulting from this situation. The effects on landscape and on the socio-spatial configuration result from the intensification caused by the dynamism of the "real estate-tourism" sector. There is a regional integration as an expression of the urban expansion of the metropolitan area of Natal. This study investigates the uniqueness of the restructuring and territorial integration of coastal areas and the strategies of the circuit of capital accumulation formed by linking the real estate to tourism. It is intended to increase the understanding about the strategies of tourism, real estate and public policy agents involved in this territorial reconfiguration and in the fund-raising needed for the investments, to understand the existing social and environmental effects and their future trends and also to understand the forms of spatial production as results from the practices of approaching the land transformation and the tourism valorization of the landscape, in a synchronous manner, first in the Northeast region and, as a focal study, in the Metropolitan Area of Natal. Likewise, it is intended to apprehend the current processes of metropolization of the eastern coast of Rio Grande do Norte, in addition to indicate its physical-territorial transformation and the types of projects/developments promoted by the market in the recent period. Based upon analysis undertaken for the Metropolitan Region of Natal RN, this piece of work presents some considerations on possible legal instruments that can be adjusted to the municipalities which are experiencing the impact of this peculiar and recent phenomenon in the region, caused by the arrival of the real estate-touristic capital. It is also intended to point out basic proposals to the forms of public intervention, in a speculative way, starting from a Metropolitan Planning project within a medium and long term

This study aims at solidifying the theoretical bases to provide, above all, an explanation for this phenomenon which currently happens, with a scenario of social, political, economic and cultural transformations worldwide in medium cities. Nevertheless, because it has different dimensions from its transformation axes, gentrification comes with change, but also with the introduction of a new purpose in the space using and occupation, outlining in this context the identity of places from the formation of centralities with the presence of flows with social and economic dynamicsThe current forms of geographic space appropriation show the directions of the senses and ideological profile which recreates the meanings and uses of content and materials from descriptions of a historical past. However, today there is an economic context in the urban space which refers to a search of strategies for change, i.e., the acquisition of parameter aimed at meeting the demands of the relationship between capital and labor, which ends up overriding some actions for the specification of the transformation methods within the urban space to be explained by new needs and also by the agents from the value adding to their interests and investments. Thus, we assume that the appreciation/gentrification of urban spaces may or may not result from the building of a public space, since the dialogic structure as a place of political interaction externalize conflicts and disagreements in general; it keeps segregating spaces. As new spaces are transformed, the access to them tends to happen with particular restriction, whereas some places like parks, shopping malls, high-rise and horizontal condos are the scene for major professional and family events. In this context, the gentrification process is used to designate interventions in the urban environment, in certain city spaces which are considered central to public and private investments. A historical place is permitted to be presented as a scenario, a stage full of attractions, through the transformation process. Studying gentrification consists of an analysis of the underlying interests in the transformation of these areas, and especially of the assessment of the interest level in the private sector to partner in order to modify the landscape. Gentrification results from the transformation processes of capital, which influences the efforts and investments application in order to establish and achieve optimal economic growth, focusing on a location socio-culturally centered in the urban space. Thus, the urban social structure develops in the light of some questions that relate not only the cities growth but also environmental conditions it provides in cities like Mossoro, State of Rio Grande do Norte, Brazil 2005 a 2011.

O trabalho apresentado nesta tese, tem como objetivo responder à questão de perceber se existe relação entre o capital psicológico positivo e a procura de emprego. Realizamos um estudo longitudinal que decorreu ao longo de cinco meses para encontrarmos possíveis respostas à questão levantada, em que aplicamos um questionário onde analisámos as diversas características psicológicas positivas que compõem o Capital Psicológico Positivo (auto-eficácia; otimismo; esperança e resiliência), o questionário foi aplicado a 82 indivíduos à procura de emprego, dos quais 20 foram admitidos. O que o nosso estudo concluiu foi que a auto-eficácia mediada pelo fator resiliência tem uma importância vital no processo de seleção, ou seja, os candidatos com maior perceção de auto-eficácia foram aqueles que foram admitidos. Estes resultados mostram que as organizações valorizam candidatos confiantes em si e nas suas capacidades, naquilo que sabem fazer. No final do estudo apresentamos algumas investigações futuras sobre este tema. ABSTRACT: The work reported in this thesis addresses the research question of how positive psychological capital related with job search. We developed a longitudinal study for five months to find possible answers to this question, we use a questionnaire in which we analyze the positive psychological components of positive psychological capital (self­efficacy, optimism, hope and resilience), this questionnaire was applied to 82 persons looking for a job, of this 20 were admitted. Our work shows that self-efficacy mediated by resilience has a vital importance in the selection process, this fact point that the candidates with a better perceived self-efficacy were the chosen. This results also points for the fact the organizations prefer candidates confidantes on themselves and on their capabilities, in what they know to do. At the end we present future investigations about this theme.

The oil companies in the area in general are looking for new technologies that can increase the recovery factor of oil contained in reservoirs. These investments are mainly aimed at reducing the costs of projects which are high. Steam injection is one of these special methods of recovery in which steam is injected into the reservoir in order to reduce the viscosity of the oil and make it more mobile. The process assisted gravity drainage steam (SAGD) using steam injection in its mechanism, as well as two parallel horizontal wells. In this process steam is injected through the horizontal injection well, then a vapor chamber is formed by heating the oil in the reservoir and, by the action of gravitational forces, this oil is drained down to where the production well. This study aims to analyze the influence of pressure drop and heat along the injection well in the SAGD process. Numerical simulations were performed using the thermal simulator STARS of CMG (Computer Modeling Group). The parameters studied were the thermal conductivity of the formation, the flow of steam injection, the inner diameter of the column, the steam quality and temperature. A factorial design was used to verify the influence of the parameters studied in the recovery factor. We also analyzed different injection flow rates for the model with pressure drop and no pressure drop, as well as different maximum flow rates of oil production. Finally, we performed an economic analysis of the two models in order to check the profitability of the projects studied. The results showed that the pressure drop in injection well have a significant influence on the SAGD process.

The world has many types of oil that have a range of values of density and viscosity, these are characteristics to identify whether an oil is light, heavy or even ultraheavy. The occurrence of heavy oil has increased significantly and pointing to a need for greater investment in the exploitation of deposits and therefore new methods to recover that oil. There are economic forecasts that by 2025, the heavy oil will be the main source of fossil energy in the world. One such method is the use of solvent vaporized VAPEX which is known as a recovery method which consists of two horizontal wells parallel to each other, with a gun and another producer, which uses as an injection solvent that is vaporized in order to reduce the viscosity of oil or bitumen, facilitating the flow to the producing well. This method was proposed by Dr. Roger Butler, in 1991. The importance of this study is to analyze how the influence some operational reservoir and parameters are important in the process VAPEX, such as accumulation of oil produced in the recovery factor in flow injection and production rate. Parameters such as flow injection, spacing between wells, type of solvent to be injected, vertical permeability and oil viscosity were addressed in this study. The results showed that the oil viscosity is the parameter that showed statistically significant influence, then the choice of Heptane solvent to be injected showed a greater recovery of oil compared to other solvents chosen, considering the spacing between the wells was shown that for a greater distance between the wells to produce more oil

Nearly 3 x 1011 m3 of medium and light oils will remain in reservoirs worldwide after conventional recovery methods have been exhausted and much of this volume would be recovered by Enhanced Oil Recovery (EOR) methods. The in-situ combustion (ISC) is an EOR method in which an oxygen-containing gas is injected into a reservoir where it reacts with the crude oil to create a high-temperature combustion front that is propagated through the reservoir. The High Pressure Air Injection (HPAI) method is a particular denomination of the air injection process applied in light oil reservoirs, for which the combustion reactions are dominant between 150 and 300°C and the generation of flue gas is the main factor to the oil displacement. A simulation model of a homogeneous reservoir was built to study, which was initially undergone to primary production, for 3 years, next by a waterflooding process for 21 more years. At this point, with the mature condition established into the reservoir, three variations of this model were selected, according to the recovery factors (RF) reached, for study the in-situ combustion (HPAI) technique. Next to this, a sensitivity analysis on the RF of characteristic operational parameters of the method was carried out: air injection rate per well, oxygen concentration into the injected gas, patterns of air injection and wells perforations configuration. This analysis, for 10 more years of production time, was performed with assistance of the central composite design. The reservoir behavior and the impacts of chemical reactions parameters and of reservoir particularities on the RF were also evaluated. An economic analysis and a study to maximize the RF of the process were also carried out. The simulation runs were performed in the simulator of thermal processes in reservoirs STARS (Steam, Thermal, and Advanced Processes Reservoir Simulator) from CMG (Computer Modelling Group). The results showed the incremental RF were small and the net present value (NPV) is affected by high initial investments to compress the air. It was noticed that the adoption of high oxygen concentration into the injected gas and of the five spot pattern tends to improve the RF, and the wells perforations configuration has more influence with the increase of the oil thickness. Simulated cases relating to the reservoir particularities showed that smaller residual oil saturations to gas lead to greater RF and the presence of heterogeneities results in important variations on the RF and on the production curves

O processo de Harmonização Contabilística é um processo que surge em consequência do processo de Globalização da Economia. Com a evolução do comércio global, exige-se que a informação contabilística seja mais uniforme entre os diversos países/continentes, para que os utilizadores dessa informação possam tomar as melhores decisões. Em Portugal, o referido processo tem sido influenciado pela regulamentação produzida a nível europeu. Fruto desta influência, a partir de 01 de janeiro de 2005 as empresas cotadas em bolsa ficaram obrigadas a aplicar as International Accounting Standards/International Financial Reporting Standards (IAS/IFRS) e as Standing Interpretations Committee/International Financial Reporting Interpretations Committee (SIC/IFRIC), de acordo com o Regulamento 1606/CE/2002. Em 2003, a CNC elaborou um projeto de linhas de orientação para um novo modelo de normalização contabilística, documento que serviria de base ao Projeto do novo Sistema de Normalização Contabilística (SNC), tendo o novo SNC entrado em vigor em 1 de janeiro de 2010. É, pois, dentro destas alterações introduzidas no normativo contabilístico nacional que se desenvolve este estudo, que tem como principal objetivo analisar e quantificar os impactos sobre o Capital Próprio, decorrentes da adoção do SNC em empresas do setor agrícola. Para o efeito utilizamos uma amostra de 6980 empresas do referido setor. Dos resultados obtidos concluímos que 4910 empresas, o que representa 70,34% do total, apresentaram alterações no Capital Próprio. A rubrica Reserva foi aquela que mais vezes sofreu variações, tendo sido alterada no Balanço de 4008 empresas. As alterações no Capital Próprio têm impacto nos rácios de Solvabilidade Financeira e Autonomia Financeira. Uma análise desses indicadores permitiu-nos concluir que, em termos de Solvabilidade Financeira, 6,32 % das empresas (441) pioraram a sua situação, 81,15 % (5664) mantiveram-na inalterada e 6,72 % (469) melhoraram a sua Solvabilidade Financeira. Relativamente à Autonomia Financeira as variações foram menos significativas, pois 99,07 % (6915 empresas) mantiveram inalterado o seu desempenho, 0,11 % (8 empresas) pioraram a sua situação relativamente ao presente indicador e 0,19 % (13 empresas) melhoraram. No entanto, estes indicadores de equilíbrio financeiro devem ser analisados num contexto de transição, uma vez que não se verificou um real aumento ou diminuição da estrutura de Capitais Próprios destas empresas, mas apenas uma nova reconfiguração contabilística.
