The presented work is an essay rather than a scientific dissertation. The author wants to put an impact on the source of conflicts regarding the complex subject of heritage management and conservation in comparison with the local needs and the given context. The paper attempts to show the role of local communities and their cooperation with authorities as well as the effects of such cooperation. The area of research comprises the problems arising in the field of implementing external rules on the local field, challenges appearing regarding the needs of local communities and the efforts of official authorities trying to implement the principles of the conventions. The problems arise when local communities display the lack of understanding and do not share the common idea of heritage conservation. This is caused mainly by the decreasing possibilities of comfortable life. The author tries to identify the main and wrongful approaches as ‘Gone with the Wind’, ‘The Prince and The Pauper’, ‘Heart of Darkness’ or ‘Scarlet letter’. The focus will be put to explain what the areas are where a mutual misunderstanding arise and why all parts to the problem present different points of view. What creates a value? Is it a heritage object or maybe the other values need a stronger protection? When the general duty and the need to protect the heritage is regarded as a controversy and when it is considered as a value within a given community? The international public interest in heritage protection is often regarded as an attempt to diminish the sovereign power of the community and provokes severe controversies and tensions. The major problem envisaged today seems to be the massive and increasing urbanisation and the destruction of the vestiges still existing of traditional cultures, when we consider century urban post-industrial districts of Upper Silesia in Poland, the medieval cities in Western Europe, the traditional nomad Masaya villages in Kenya or the remains of vanished cultures in various regions of Asia. The preferred platform of cooperation between the parts of the conflict includes divergent needs, beliefs and practices of communities and the possible fields of reconciling the abovementioned. Chosen examples of the best practices considering mutual cooperation will be underlined.

The present research results of the studies and debates inherent in PhD in Education at the Graduate Program in Education at the Federal University of Uberlândia, belonging to the Research Line "Politics and Knowledge in Education." This thesis aims to analyze the contradictory meaning of education as training human history, specifically educational representative under the logic of the industrial business associated FIEMG (Federation of Industries of the State of Minas Gerais) in the context 1961-1974. This definition is justified by the historical fact that it was a period marked by the cyclical crises of capital and their impacts in the final phase of the industrialization process in Brazil: it starts with one of the apexes of economic growth in the country , driven by national developmental , continues with a severe political crisis in 1966 , also impacting the economic sphere, and finally, with the constant quest for economic stability even under high prices, hatch the factors that led to the Brazilian economy to the context of the "Economic Miracle". For this, it was necessary to link the debate between education and work from the perspective of historical materialism and dialectical their subsidies theoretical-methodological and epistemological. In the first chapter, we designed a "State of the art" category "human formation", conceived as a process of education and history, from the Marxist assumptions, aiming at the reconstruction of concepts and meanings of which is the formation of workers in contradictory logic, the bias of comprehensive training and the prospect of capital accumulation. Then, in the second chapter, we present a review about industrialization, the industrial business and its development perspective 1961-1974. The third chapter was established on a contextualization of the state and its peculiarities, the industrial business and its proposed development both nationally and at the state (Minas Gerais). Finally, in the fourth chapter, was organized dialogue with the sources, from a historical survey of the shares of the industrial business with an emphasis on education, which converged in a pedagogy industrial consolidation in line with the political and economic conditions specific period from 1961 to 1974. It has mailing bibliographic reference business thinking expressed in the concreteness of training workers and industry of Minas Gerais, in agreement with the demands of work and training of mining companies. The thesis of this study is the defense that the corporate actions which constituted pedagogy industrial concepts were articulated to political and economic development in Brazil, since the discipline to work imposed by such conceptions met the human worker training geared to the accumulation the general capital and industrial capital in particular. Establish, therefore, different logics, the state level, the scope of private foreign capital and domestic private capital, which came up the process of capital accumulation, loading, contradictorily, the possibilities of building the human beyond capital, or a teaching job.

Faced with an agribusiness expansion scenario and the increase in fertilizer consumption due to the exponential growth of the population, it is necessary to make better use of existing reserves, by obtaining products of better quality and in adequate quantities to meet demand national. In Tapira Mining Complex, Vale Fertilizantes, the phosphate concentrate is produced with content of 35.0% P2O5 from ore with content of about 8.0% P2O5, which are intended to supply Complex Industrial Uberaba and Araxá Minero Chemical Complex for the production of fertilizers. The industrial flotation step responsible for the recovery of P2O5 and hence the viability of the business is divided into the crumbly, grainy and ultrathin circuits, and, friable and granular concentrate comprise the conventional concentrated. Today only 14.7% of the mass which feeds the mill product becomes, the remainder being considered losses in the process, and the larger mass losses are located in the waste of flotation, representing 42.3%. From 2012 to 2014, the daily global mass recovery processing plants varied from 12.4 to 15.9% while the daily metallurgical recovery of P2O5 from 48.7 to 82.4%. By the degree of variability, it appears that the plant operated under different conditions. Seen this, this study aimed to analyze the influence of operational and process variables in P2O5 mass and metallurgical recoveries of industrial flotation circuits of grainy, crumbly and ultrathin. And besides was made an analysis of the effect of ore variables, as degrees, hardnesse and the ore front 02 percentage, in global recoveries of processing plant and the effect of dosages of reagents in the recoveries obtained from the bench flotation using the experimental design methodology. All work was performed using the historical database of Vale Fertilizantes of Tapira-MG, where all independent variables were dimensionless as the experimental range used. To make the statistical analysis it used the response surface technique and the values of the independent variables that maximize recoveries were found by canonical analysis. In the study of industrial flotation circuit crispy were obtained from 41.3% mass recovery and 91.3% metallurgical recovery P2O5, good values for the circuit, and the highest recoveries occur for solids concentration of the new flotation power between 45 and 50%, which values are assigned to the residence time of the pulp in cells and industrial flotation columns. The greater the number of ore heaps resumed on the higher the mass recovery, but in this scenario flotation becomes unstable because there is enormous weight variation in the feed. Higher recoveries are obtained for mass depressant dosage exceeding 120 g / t for synthetic collector dosage of 11.6%. In the study of industrial flotation circuit of the granulate were obtained 28.3% to 79.4% mass recovery and metallurgical recovery of P2O5 being considered good values for the circuit. Higher recoveries are obtained when the front ore 02 percentage is above 90%, because the ore of this front have more clear apatite. Likewise recoveries increase when the level of pulp rougher step is highest due to the high mass of circulating step receives loads. In the analysis of industrial flotation circuit of the ultrafine were obtained 23.95% of mass recovery, and the same is maximized to depressant dosage and the top collector 420 and 300 g / t, respectively. The analysis of the influence of variables ore, it was observed that higher recoveries are obtained for ores with P2O5 content above 8.0%, Fe2O3 content in the order of 28% forward and 02 of ore percentage of 83%. Hard ore percentage has strong influence on recoveries due to mass division in the circuit that is linked to this variable. However, the hard ore percentage that maximizes recoveries was very close to the design capacity of the processing plant, which is 20%. Finally, the study of the bench flotation, has noted that in friable and granular circuits the highest recoveries are achieved for a collector dosage exceeding 250 g / t and the simultaneous increase of collector dosage and synthetic collector percentage contributes to the increase recovery in the flotation, but this scenario is suitable to produce a concentrate poorer in terms of P2O5 content, showing that higher recovery is not always the ideal scenario. Thus, the results show the values of variables that provide higher recoveries in the flotation and hence lower losses in the waste.

Tendo por base o contexto histórico e patrimonial no qual se desenvolveu o interesse pelo património industrial em Portugal, a partir do último quartel do século passado, este trabalho procura ser um contributo para a valorização histórica e patrimonial de um espaço industrial de grandes dimensões como foi o caso do Complexo Industrial da C.U.F. no Barreiro. O trabalho estrutura-se em duas partes, na primeira parte abordamos o tema Património Industrial na sua génese e enquadramento histórico como conceito e suas perspetivas de preservação e valorização; seguidamente faremos uma pequena síntese histórica do Barreiro até ao Complexo Industrial da C.U.F., onde abordaremos também o aumento populacional e o crescimento urbano, passando pelo problema da habitação e o surgimento dos Bairros Operários até aos espaços de lazer e catividades culturais ligadas ao Operariado, não esquecendo as estruturas de saúde, assistência, lazer e as politicas sociais. Na segunda parte abordaremos a importância de valorizar o património industrial e consequentemente o Complexo Industrial com a proposta de um programa de valorização do mesmo, através da criação de núcleos museológicos e de um roteiro de Património Industrial. ABSTRACT: The Human Facet of the Industrial Complex of C.U.F.- a Heritage to Preserve The foundation of this Project is the historical heritage for which developed the interest in Portugal's industrial heritage from the last quarter of the past century. This project has the intention to contribute to the historical and heritage valorization of one of the biggest industrial complexes, which was the case of the Industrial Complex C.U.F. in Barreiro. This project has two parts, the first part will be about defining the theme of industrial heritage and its genesis and the historical setting as a concept and its perspectives of preservation and valorization; afterwards, we will do a small historical synopsis of Barreiro including the Industrial Complex of C.U.F., where we will also refer to the increase in population growth and the urban development, followed by the housing problem and consequently the increase of working class neighborhoods, even to the prices of leisure and culture activities related to the working class, not forgetting the health structures, assistance, leisure and social politics. ln the second part, we will also talk about the importance of valorizing industrial heritage, and subsequently the Industrial Complex, with a proposal of a valorization programme of the Complex with the creation of a museological core as well as an industrial heritage guide.

En el Ecuador, a partir del año 2010, por resolución de la Superintendencia de Compañías, las compañías que se encuentran reguladas por este organismo, deben aplicar de manera obligatoria las Normas Internacionales de Información Financiera (NIIF), cuyo objetivo fundamental es que los Estados Financieros reflejen la realidad de la compañía y puedan ser comparables a nivel mundial, permitiendo una mayor competitividad y mejor toma de decisiones. La exención de la NIIF 1 permite optar en la fecha de transición a las NIIF por la medición de una partida de propiedad, planta y equipo por su Valor Razonable, y utilizar este valor como Costo Atribuido lo que implica contablemente un incremento en el valor tanto del activo como del patrimonio así como el reconocimiento de impuestos diferidos. Las NIIF no están diseñadas para realizar reportes impositivos por lo que la revaluación en los elementos de propiedad, planta y equipo generó implicaciones tributarias en la determinación del Impuesto a la Renta sobre todo en el sector industrial porque las compañías que pertenecen a este sector tienen en sus activos un valor significativo en propiedad, planta y equipo. El presente trabajo de investigación se lo realizó a través de un estudio de caso a una de las compañías objeto de estudio así como también a través de la aplicación de encuestas a las compañías que pertenecen al sector industrial del Cantón Cuenca y del análisis de la información que consta en la página de la Superintendencia de Compañías de dichas compañías.
