Deep-sea mining activities are expected to commence in the next decade; the International Seabed Authority (ISA) has already issued twenty nine exploration licenses for polymetallic nodules, polymetallic sulphides and polymetallic crusts. The ISA is seeking to approve the exploitation regulations for polymetallic nodules in the next two years, but there are significant research and knowledge gaps that still have to be explored. The discharge of dewatering plumes, the analysis of the effect of vortex-induced vibrations (VIV) on mining risers, and the development of updated and detailed economic models -which are among the most pressing ones - are addressed in this thesis. PLUMEX field studies were conducted in the Pacific Ocean to create and monitor six dewatering plumes. The data obtained from the experiments will be used to validate analytic and numeric plume models that will help to assess the environmental impacts. Additionally, a preliminary VIV analysis of a simple riser configuration was conducted to show the significant impact of VIV on the fatigue life. The results showed that the fatigue life could be reduced to less than one year. Lastly, an independent and thorough economic model is being developed at MIT to allow the simulation of different scenarios and forecast the economic result of a polymetallic nodule exploitation. The ISA will consider the results from the model to determine the royalties and fees that will be paid by future contractors in order to share their benefit with the humankind.

Повний текст джерелаThe dissertation presents the work done under the scope of the NP7 Self-Learning project regarding the design and development of the Adapter component as a foundation for the Self-Learning Production Systems (SLPS). This component is responsible to confer additional proprieties to production systems such as lifecycle learning, optimization of process parameters and, above all, adaptation to different production contexts. Therefore, the SLPS will be an evolvable system capable to self-adapt and learn in response to dynamic contextual changes in manufacturing production process in which it operates. The key assumption is that a deeper use of data mining and machine learning techniques to process the huge amount of data generated during the production activities will allow adaptation and enhancement of control and other manufacturing production activities such as energy use optimization and maintenance. In this scenario, the SLPS Adapter acts as a doer and is responsible for dynamically adapting the manufacturing production system parameters according to changing manufacturing production contexts and, most important, according to the history of the manufacturing production process acquired during SLPS run time.To do this, a Learning Module has been also developed and embedded into the SLPS Adapter. The SLPS Learning Module represents the processing unit of the SLPS Adapter and is responsible to deliver Self-learning capabilities relying on data mining and operator’s feedback to up-date the execution of adaptation and context extraction at run time. The designed and implemented SLPS Adapter architecture is assessed and validated into several application scenario provided by three industrial partners to assure industrial relevant self-learning production systems. Experimental results derived by the application of the SLPS prototype into real industrial environment are also presented.

Resumo: Foram sintetizadas sílicas mesoporosas híbridas a partir da funcionalização da SBA-15 e filossilicatos de cobalto e níquel com macrociclos orgânicos contendo sítios básicos para a sorção dos íons metálicos tóxicos Pb, Cd e Cu. A SBA-15 e o filossilicatos de magnésio também foram modificados com cadeias orgânicas contendo diferentes quantidades de átomos de enxofre para serem aplicados na sorção de íons complexos de ouro e de metais do grupo da platina com o intuito de otimizar as condições adotadas para a extração destes metais preciosos de seus minérios. Os materiais contendo macrociclos orgânicos foram formados a partir de sucessivas reações nas superfícies com diferentes moléculas orgânicas para conter os centros básicos nitrogênio, oxigênio e enxofre. As técnicas de caracterização confirmaram as formações das estruturas mesoporosas e lamelares, mostrando a presença de cadeias orgânicas pendentes contendo os grupos funcionais de interesse. Os híbridos funcionalizados com macrociclos apresentaram-se efetivos nas sorções dos metais tóxicos, com alta capacidade para o íon Pb quando estão funcionalizados com macrociclos contendo enxofre. Enquanto que, no geral, as capacidades de sorção de todos os materiais tornaram-se maiores com o aumento das quantidades de centros básicos. Estas capacidades de sorção ainda sofrem um aumento após a formação dos macrociclos. As sorções dos complexos de metais preciosos foram efetivas em todos os casos, com destaque para tetracloroaurato e tetracloropaladato, que apresentaram altos valores de sorção. Ótimos valores também foram obtidos na sorção do complexo aurotiossulfato com o filossilicato de magnésio funcionalizado com grupos tiol. As titulações calorimétricas dos metais tóxicos com as matrizes contendo macrociclos orgânicos indicaram processos favoráveis de interação dos sítios básicos com os cátions em solução aquosa, devido a valores negativos de energia de Gibbs, em um processo espontâneo, e valores positivos de entropia. Os valores de entalpia mostram que todas as interações metais/centros básicos na interface sólido/líquido são exotérmicas
Abstract: This thesis reports the syntheses of hybrid mesoporous sílicas, through the functionalization of SBA-15, and cobalt and nickel phyllosilicates functionalized with organic macrocycles containing basic sites for the sorption of the toxic metallic ions Pb, Cd and Cu. SBA-15 and magnesium phyllosilicates were also modified with organic chains containing different amounts of sulfur atoms to be applied to the sorption of complex ions of gold and platinum group metals. This is done in the aim of optimizing the conditions adopted in the extraction of these precious metals from their ores. The materials with pendant organic macrocycles were formed through successive reactions on the surfaces with different organic molecules possessing nitrogen, oxygen and sulfur basic centers. The characterization techniques confirmed the formation of mesoporous and layered structures, showing the presence of pendant organic chains with the desired functional groups. The hybrids functionalized with macrocycles were effective in the sorption of toxic metals, with high sorption capacities for Pb when the solids are functionalized with macrocycles containing sulfur atoms. Whereas the sorption capacities of all materials were improved with the increase of basic centers amounts. These sorption capacities were even improved after the macrocycles formation. The sorption of precious metals complexes were effective in all cases, especially for tetrachloroaurate and tetrachloropalladate, which presented high sorption values. Exceptional values were also acquired in the sorption of aurothiosulfate complex by the magnesium phyllosilicate functionalized with thiol groups. The calorimetric titrations of toxic metals with the matrices containing organic macrocycles indicated favorable processes for the interaction between the basic centers and the cations in aqueous solution, due to negative values of Gibbs energy, in a spontaneous process. The results also indicated positive values of entropy. The values of enthalpy showed that all the metal/basic centers interactions at the solid/liquid interface are exothermic

Повний текст джерелаThis thesis explores the application of the mathematical principles of Holmberg and his collaborators.These principles are described in the book Rock blasting and explosives engineering which aims to demonstrate in a practical way the importance of proper drilling and blasting mesh design. This was completed, first of all, with geomechanical mapping (RMR), analysis of the start to be used, as well as the length of holes and the optimal explosive for the bait and the loading column. This research was carried out at the Santa María Mining Unit of Compañía Minera Poderosa S.A., where it was shown that the diameter change in the starter relief drills from 38 mm to 64 mm and the additional use of 8-foot holes for the 2.5 m x 2.7 m section, contributes to being efficient in every shot. In this same instance, it was demonstrated that, optimally applying the mathematical principles used the amount of explosives use can be significantly reduced, reflected in economic savings per shot. The results obtained with the new design are: the power factor went from 1.23 to 1.15 kg/t reducing a 6.8 %, the advance per shot from 1.51 to 2.10 m increasing a 39.2 % and the linear load factor from 23.24 to 21.02 kg/m reducing a 9.6 %; which translates into a monthly savings on the work front of S/. 21,421.12.

Повний текст джерела[CAT] A lo llarc de l'historia, l'home ha explotat els recursos minerals de la terra per a la seua supervivencia i desenroll tecnologic sense un equilibri en la seua regeneracio. Donat el creiximent de la poblacio mundial i la reduccio de recursos, l'home escomençà a buscar nous deposits que se trobaren en la decada de 1960 en les fondaries dels oceans. En estos, l'humanitat empezò a pensar en extraure els minerals d'estos deposits i aço llevò al naiximent de Deep Sea Mining (DSM). Les conseqüencies de les activitats mineres en les fondaries del mar no se coneixen realment i els efectes poden ser diferents: contaminacio acustica, contaminacio lluminica, contaminacio quimica, destruccio de l'habitat, fragmentacio de l'habitat i perdua d'especies que son la base de molts sistemes vitals. L'impacte acustic d'estes activitats pot tindre importants conseqüencies en les especies marines, encara que este es el tema mes ignorat. El proposit d'este proyecte de doctorat fon proporcionar una comprensio basica dels possibles impactes acustics del DSM en la biodiversidad abans de que escomencen estes activitats. Per a fer aço, el proyecte de doctorat s'organisà en varis passos. Primer, durant un experiment indoor, s'analisaren les respostes bioquimiques en invertebrats somesos a estrés acustic, Arbacia lixula i Mytilus galloprovincialis. Els resultats demostraren efectes significatius en l'activitat de citotoxicidad, expressio d'heat shock protein (HSPS) i activitats enzimáticas (esterasa, fosfatasas alcalina, peroxidasas) en el liquit celomático dels capellanets de mar somesos a estrés acustic. Tambe s'observaren efectes significatius en el nivell de glucosa, la citotoxicidad i les activitats enzimáticas (esterasa, fosfatasa alcalina, peroxidasas) de la glandula digestiva de la clochina. En segon lloc, s'analisaren les respostes bioquimiques de vertebrats i invertebrats somesos in-situ a l'emissio de watergun: Chromis chromis, Holothuria tubulosa i Arbacia lixula. se trobaren efectes significatius sobre els nivells de cortisol en peixos i les activitats enzimáticas (esterasas, fosfatasas alcalines, peroxidasas y superoxide dimutases) en peristomes de capellanet de mar. Ademes, les respostes bioquimiques enzimáticas analisades en els decorreguts celómicos dels equinoderms fon significativa nomes per A. lixula i nomes en l'activade peroxidasica. Tercer s'estudiaren els canvis de comportament en les condicions experimentals en jovenils de Sparus aurata somesos a 4 freqüencies d'emissio acustica diferents. Este experiment demostrà que nomes les baixes freqüencies tingueren efectes en totes les respostes comportamental: alçada de natacio, motilidad i escampada del grup. Sobre la base de les senyes de comportament obtinguts in vivo en peixos jovens, se creó un model numeric per a predecir els impactes de diferents freqüencies d'emissio acustica. Utilisant els resultats obtinguts i la bibliografia cientifica, se propongue un primer estandart tecnic que es util per a la mineria.
[EN] Throughout history, man has exploited the earth's mineral resources for its survival and for technological development without regard for their regeneration. Given the growth of the world population and given the fall in resources, man started looking for new deposits, which were found in 1960s in the ocean depths. Humankind then began to consider extracting minerals from these deposits and this gave origin to Deep Sea Mining (DSM). The consequences of mining activities in the deep sea are not entirely known and the effects can be varied: noise pollution, light pollution, chemical pollution, habitat destruction, habitat fragmentation and the loss of species which we consider the basis of many life systems. The acoustic impact of these activities could have significant consequences on marine species; nevertheless, this has been the most overlooked issue to date. The aim of this PhD project was to provide baseline knowledge of possible acoustic impacts of DSM on biodiversity before mining begins. In order to do this, the PhD project was organised into 3 different stages. First, during an indoor experiment, the biochemical responses of invertebrates Arbacia lixula and Mytilus galloprovincialis subjected to acoustic stress were analysed. The results showed significant changes in cytotoxicity activity, expression of heat shock proteins (HSPs), and enzyme activities (esterases, alkaline phosphatases, peroxidases) in the coelomic fluid of sea urchins subjected to acoustic stress. Significant effects were also observed in glucose levels, cytotoxicity and enzyme activities (esterase, alkaline phosphatase, peroxidase) in the digestive gland of the mussel. Second, the biochemical responses of vertebrates and invertebrates subjected in-situ to watergun emission were analysed: Chromis chromis, Holothuria tubulosa and Arbacia lixula. Significant effects on fish cortisol levels and on enzyme activities in sea urchin peristomes were found. Furthermore, the enzyme biochemical responses analysed in the coelomic fluids of echinoderms showed significant effects only in A. lixula sea urchin and only in peroxidase activity. Third, behavioural changes in experimental conditions were studied in juveniles of Sparus aurata subjected to 4 different acoustic emission frequencies. This experiment showed that only low frequencies had effects on all the behavioural responses analysed: swimming height, motility and dispersion of the group. Based on behavioural data obtained in vivo on juvenile fish, a numerical model was created to predict the impacts of different acoustic emission frequencies. Using the results obtained and literature, a first technical standard useful for mining activities was drawn up.

Повний текст джерелаThe research work was carried out in the Antapaccay mining operation of the company San Martin Contractors Generals S.A during the 2018 - 2019 period, an operation that identified substandard acts (unsafe behaviors) as the main causes of their accidents in recent years. Given this situation, the research sought to implement the Behavior Based Safety program with the purpose of preventing and reducing the unsafe behaviors of workers who could generate events during the company's work activities. The work began by raising awareness among all company staff from top management, the line of command and collaborators, seeking the participation and training of observers for the program. Then the definition of responsibilities was made by each personnel involved in the program (Chief of Security, researchers, project manager, area managers and observers). Likewise, the preparation and personalization of the observation card was carried out based on the critical risks and the causes of the accidents of the company in recent years. Afterwards, the observers who participated in the program, divided into two shifts of the operation, were trained. The presentation and diffusion of the program occurred at the security stop with the work of the present collaborators. The collection of information was carried out at the end of the day and after the process of behavioral intervention, the booklets were registered and processed in the database created to develop an analysis of trends and propose immediate corrective actions. The research measured the variation of safe behavior indexes versus unsafe behaviors on a daily, weekly and monthly basis, evidencing that behavioral safety programs can increase safe behaviors and are a great complement and support in the search for operational controls and corrective measures. Mining safety management system. Finally, the conclusions and recommendations are presented according to the results presented.

Повний текст джерелаSyftet med uppsatsen är att få en djupare förståelse för hur fem elever som ligger högt på en provångestskala upplever och hanterar provsituationer. Metoden som användes var kvalitativ och utfördes i semistrukturerad intervjuform. Fem elever som läser i grundskolans senare år valdes ut genom flerstegsurval. Först gjordes ett tillgänglighetsurval och sedan subjektivt urval via en enkät som mäter provångest av Oostdam och Meijer (2003). De elever som hamnade i gruppen ”höga poäng” valdes ut för intervju.
Eleverna i studien finner provsituationer som obehagliga och förtränger att de ska ha prov. De blir ofta blockerade i en provsituation och får därmed problem med att återminnas relevant information. De har en låg tro på sin prestationsförmåga och ingen av eleverna har pratat med sina lärare om hur de känner i en provsituation. Vilka åtgärder som kan sättas in för att underlätta elevernas provskrivande varierade mellan informanterna. Dock framkom att tidsbegränsningen vid provskrivande har en negativ effekt på deras prestation. En annan vanlig åtgärd är att eleverna får lära sig hantera sina känslor i en provsituation.

Повний текст джерелаI den här studien undersöks om det är bristande tidsuppfattning som orsakar sämre prospektivt minne hos barn med diagnos ADHD. Studien syftar även till att utreda vad prospektivt minne har för relation till arbetsminne och exekutiva funktioner.
Studien har genomförts genom att två grupper, en grupp barn med diagnos ADHD och en kontrollgrupp, har utfört uppgifter som ger mått på prospektivt minne, tidsuppfattning, arbetsminne och exekutiva funktioner. Barnen i ADHD-gruppen har även deltagit i en intervju.
Resultaten visar att det inte finns någon skillnad i prestation på den prospektiva minnesuppgiften, men att barnen i ADHD-gruppen utvecklar en sämre strategi än barnen i kontrollgruppen för att klara uppgiften. Resultaten visar att barnen med ADHD presterar sämre än andra på tidsuppfattningsuppgiften, däremot visas ingen skillnad mellan grupperna i prestation på exekutiva funktioner eller arbetsminne. Det går inte med uppgifterna i den här studien att visa på några direkta samband mellan de olika undersökta funktionerna och prospektivt minne.
This study examines whether a lacking sense of time causes a negative effect on prospective memory in children with ADHD. In addition, the study investigates how prospective memory is related to working memory and executive functions.
The study explores two groups of children. One group consists of children diagnosed with ADHD and the other one is a control group. The two groups carried out tasks aimed at measuring prospective memory, sense of time, working memory, and executive functions. The children with ADHD also were interviewed.
The results yielded no difference between the groups in regards of the prospective memory assignment. However, the children in the ADHD group used a poorer strategy to solve the assigned task. The results further demonstrate that the children with ADHD presented a poorer outcome in the concept of time assignment. In contrast, there was no clear distinction between the groups in terms of executive functions and working memory. The study found no direct relationship between the examined functions and prospective memory.

This research is carried out by using the Holmberg mathematical algorithm that allows defining a numerical model for the design of a drilling mesh, and with the consideration of operational criteria, finding a technical mesh that allow improving the performance of exploration and development labors. To achieve it, the type of rock (type III - A) and the geomechanical characteristics present in it were considered as a fixed variable; the diameter of the drill as a fixed variable; the type blasting attachment and explosives as changeable, since the use of guides, safety wick and dynamite was replaced with the use of non electric detonators (Exaneles) and encapsulated emulsions. The opportune and pertinent standardization of the drilling and blasting process allowed obtaining the following results: the advance per shot was to 1.62 m, the load factor was reduced to 13.46 kg/m and the power factor decreased considerably.

Повний текст джерелаThis essay focuses on the U.S. Navy’s former and future capability to counter thethreats of sea mines in coastal waters during sea control operations. The study isbased on a broad theoretical background. The theories I use to describe and analysethe theories and methods for warfare at sea described by Julian S Corbett in 1911.These theories forms the bias of this essay and are used to analyze the case study.The U.S. Navy has struggled with the difficult task of mine clearance operations forwell over 100 years. During August 1864 the defenders of Mobile, Alabama a portcity on the Gulf of Mexico used mines against the forces led by Rear AdmiralFarragut. These struggles have been marked by a propensity to react to current orpast mine threats in developing force structure and employment methodologies. Thisreactionary approach to mine countermeasures is identified in three recurring themes;the lack of a published doctrine, the failure to fully integrate mine countermeasureforces into the operating forces, and the fragmentary development of technologywithout the focusing element of a coherent doctrine to guide research anddevelopment efforts. These themes are recognizable in the changing minecountermeasures force structure that has resulted from the Navy's reaction to minethreats manifested in various conflicts. Naval mine countermeasures and procedureshave been historically reactionary and essentially unfocused in their evolution.Examples of these difficulties can be identified in the Wonsan harbor during theKorean War, the Gulf War, and in present day planning for expeditionary warfareemployment.Since the end of the Cold War the need for multinational cooperation has increasedwithin the framework of nations and alliances. This change has opened the door forcooperation between traditionally small coastal navies and blue water navies.

This thesis relates to the issue of accumulation of technological capabilities at the firm level, their sources (learning mechanisms) and implications for competitive business performance in natural resources industries in the context of emerging economies. During the past 40 years much progress has been made in research on technological capability accumulation at the level of companies in emerging economies. However, there are still important gaps to be exploited particularly in relation to nature and dynamics of the accumulation of intra-firm technological capabilities paths in the context of natural resources industries, especially in mining. The purpose of the research reported here is to contribute to minimize this gap. In particular, this thesis explores intra-firm variations of technological capabilities accumulation paths, their sources (underlying mechanisms of learning) and some implications that are generated for the competitive performance of the company within the mining industry in Brazil, specifically in the mining company Vale, between 1942 and 2015. To achieve this goal, research is based on the combination of literatures of technological capability accumulation, innovation, learning and industrial development for the construction of the conceptual basis. In parallel, the research draws on a qualitative and inductive research design on primary evidence based on extensive field work. This research design is operated from a single case study in depth at Vale, within three major technology areas: prospecting and mineral exploration, mining and mineral processing. Through the implementation of this strategy, the research found: (1) Paths of technological capabilities accumulation relatively distinct between the three areas of analysis. Specifically: (i) the area of mineral prospecting and exploration there was a technological follower path that achieves global leadership position in innovation and production; (ii) the area of mining also showed up a technological follower path that achieves global leadership position in innovation and production, however, with late accumulation of technological capabilities; and (iii) the area of mineral processing showed an early entrance of a world leader in innovation and production from the creation of a distinct path already mapped by global leaders. The technological capabilities accumulation paths have become similar in 2011 when the three areas presented a world leader in innovation and at the same time demonstrated indications of a stagnation process, which restricts the opportunities to entrance in new technological paths and generation of spillovers. (2) The variations found in the technological capabilities accumulation paths are explained by the way in which different underlying mechanisms of learning were combined and used by the firm. Four combinations of learning mechanisms helped to explain the different directions of technological capabilities accumulation paths in the three areas. (3) The variations in the three technological capabilities accumulation paths generated different implications for competitive performance, specifically in terms of innovative, operational / environmental and spillovers performance. The research findings generate contributions to the understanding of the intra-firm relationship between accumulation of technological capabilities and the underlying learning mechanisms. In addition contribute to the understanding of mining industry as an industry that offers opportunities for significant innovations and can contribute to the diversification of the national industry. So, this industry should get special attention from policy makers and business actions to prevent that firms with high innovative potential deconstruct their innovative capabilities and consequently limit their impact to the technological and economic development in the context of emerging economies.
Esta tese relaciona-se ao tema da acumulação de capacidades tecnológicas em nível de empresa, suas fontes (mecanismos de aprendizagem) e suas implicações para a performance competitiva empresarial, em indústrias relacionadas a recursos naturais no contexto de economias emergentes. Durante os últimos 40 anos muito se avançou no campo da pesquisa sobre acumulação de capacidades tecnológicas em nível de empresas em economias emergentes. Porém, ainda há importantes lacunas a serem exploradas particularmente em relação a natureza e dinâmica de trajetórias de acumulação de capacidades tecnológicas intra-empresariais, no contexto de indústrias relacionadas a recursos naturais, especialmente na mineração. O objetivo da pesquisa aqui reportada é contribuir para minimizar esta lacuna. Particularmente, esta tese explora variações intra-empresariais de trajetórias de acumulação de capacidades tecnológicas, suas fontes (mecanismos subjacentes de aprendizagem) e algumas implicações que são geradas para a performance competitiva da empresa, no âmbito da indústria de mineração no Brasil, especificamente na empresa mineradora Vale, no período entre 1942 e 2015. Para alcançar este objetivo, a pesquisa apoia-se na combinação das literaturas de acumulação de capacidade tecnológica, inovação, aprendizagem e desenvolvimento industrial para a construção da base conceitual. Em paralelo, a pesquisa vale-se de um desenho de pesquisa qualitativo e indutivo baseado em evidências primárias com base em extensivos trabalhos de campo. Esse desenho de pesquisa é operacionalizado a partir de um estudo de caso individual em profundidade na Vale, no âmbito de três grandes áreas tecnológicas: prospecção e pesquisa mineral, lavra, e processamento mineral. Por meio da implementação dessa estratégia, a pesquisa encontrou: (1) Trajetórias de acumulação de capacidades tecnológicas relativamente distintas entre as três áreas de análise. Especificamente: (i) na área de prospecção e pesquisa mineral observou-se uma trajetória de seguidora tecnológica que alcança posição de liderança mundial em inovação e produção; (ii) na área de lavra também evidenciou-se uma trajetória de seguidora tecnológica que alcança posição de liderança mundial em inovação e produção, porém, com acumulação tardia de capacidades tecnológicas; e (iii) na área de processamento mineral houve o alcance precoce de posição de liderança mundial em inovação e produção a partir da criação de uma trajetória distinta da já mapeada pelos líderes globais. As trajetórias de acumulação de capacidades tecnológicas convergem para uma situação similar a partir de 2011 quando as três áreas apresentaram posição de liderança mundial em inovação e ao mesmo tempo demonstraram indícios de entrada em um processo de estagnação, que restringe as oportunidades de entrada em novas trajetórias tecnológicas e de entrada em novos negócios. (2) As variações encontradas nas trajetórias de acumulação de capacidades tecnológicas são explicadas pela maneira pela qual diferentes mecanismos subjacentes de aprendizagem foram combinados e utilizados pela empresa. Foram encontradas quatro combinações de mecanismos de aprendizagem que contribuíram para explicar as diferentes direções das trajetórias de acumulação de capacidades tecnológicas. (3) As variações nas três trajetórias de acumulação de capacidades tecnológicas geraram implicações distintas para a performance competitiva, mais especificamente em termos de performance inovadora, operacional/ambiental e de novos negócios. Os resultados da pesquisa geram contribuições para o entendimento do relacionamento intra-empresarial entre acumulação de capacidades tecnológicas e os mecanismos de aprendizagem subjacentes. E contribuem para o entendimento da mineração como uma indústria que oferece oportunidades para inovações significativas que, inclusive podem implicar na diversificação do tecido industrial nacional. Portanto, tal indústria deve receber atenção especial por parte de decisores de políticas públicas e de ações empresariais para evitar que empresas com alto potencial inovativo desconstruam suas capacidades inovadoras e consequentemente limitem seus impactos para o desenvolvimento tecnológico e econômico no contexto de economias emergentes.

Повний текст джерелаThis study describes and analyzes the process of modernization of the Southeastern part of Pará since the early 1950's due to geopolitical guidelines of the State towards the integration of the Amazon's territory to the national and international economy by exploiting the potential of its natural resources. The municipality of Parauapebas, emancipated from Marabá at the end of the 1980s, emerged as a concrete result of economistic strategies of the state, through the relations of power established with the extraction and export of iron ore, led by former state company CVRD - now called Vale SA. - Parauapebas has combined the contradictions of modern activities of mining policy, focused on foreign trade, and small non - modern activities, thinly capitalized and poorly organized, rooted to the local life of the city and/or region, thereby constituting an antagonistic space. Thus, the purpose of this research is to drill down and understand the urban dynamics of Parauapebas from the perspective of the Theory of Two Circuits of Urban Economics, formulated by Santos (2008), that segments the urban areas of developing countries into Upper and Lower Circuits.Small commercial activities and services, analyzed in neighborhoods New Town and Rio Verde, allowed for a delineation on the inconsistencies, as well as a comprehension of the expressions of the lower urban economy circuit, brought forth by the excluded population of modern mining industry, which is indifferent to the local reality, and confined in terms of manpower.

Повний текст джерелаIn recent years, mining has faced a gradual decrease in the metal´s prices, generating a reduction in the profitability of the business as a result of lower mineral reserves. This has led to the adoption of operational schemes focused on the continuous improvement of each of the processes within the mining cycle, in order to reduce costs. For this reason, it is necessary to visualize each of the activities involved, such as drilling and blasting, which have a productive and economic impact on the global process. Consequently, this research focuses on optimizing rock fragmentation, through a drill and blast mesh design, by integrating the engineering concepts of blasting and characterization of the rock mass. For this, the Pearse mathematical model will be applied, in order to calculate the controllable parameters of the design and obtain the expected results. Likewise, the scope of the work includes the analysis of the productivity of the mining cycle, as well as the quantification of the impact of the proposal in terms of costs. It begins with the baseline analysis, which consists of measuring the results of current P&V mesh designs, in order to determine the variables that are generating coarse rock fragmentation. Subsequently, the mesh design proposal is proposed considering the greater amount of data and information from the Tacaza pit. Then the field work is carried out, consisting of the monitoring and control of activities, in order to comply with the designed parameters. Finally, the fragmentation results are measured in the Wipfrag software, and the productivity and costs in the mining cycle are analyzed. From the results, an improvement in fragmentation is obtained, since it is possible to reduce the diameter of rocks from 13.0 to 5.0 inches on average. This leads to an increase in the effective performance of the equipment and a cost reduction of approximately US $ 9,600 per month. These new measures generate added value for the company, through a sustainable mining operation, which seeks to make the business profitable from a holistic view of the process.

Em decorrência das novas condições de mercado, marcado pelas privatizações, crises e novos entrantes, a indústria siderúrgica têm buscado o aprimoramento da gestão dos seus processos, através da maximização da produção e otimização dos insumos. Neste contexto, essa dissertação tem como objetivo analisar os fatores determinantes da eficiência nas usinas minimills da Gerdau S.A. localizadas em diferentes países das Américas do Sul e Norte. Trata-se de um estudo descritivo e exploratório, com abordagem quantitativa, realizado com dados dos anos de 2009 e 2010. Foi utilizado o procedimento de estudo de caso, incluindo 24 unidades na análise. Com a utilização da metodologia da Análise Envoltória de Dados (DEA) foi possível mensurar a eficiência técnica e econômica relativa das usinas selecionadas e identificar as unidades benchmarks. Os principais achados evidenciam que as usinas brasileiras são as mais eficientes tecnicamente, sendo os fatores relevantes para tais resultados a sua produtividade nos insumos de número de acidentes e tempo de parada dos seus equipamentos. Um grupo de usinas americanas também foi considerado tecnicamente eficiente se destacando na produtividade dos inputs de ativo operacional e mão-de-obra. Ao substituir os insumos por seus preços relativos fica evidente a superioridade nos resultados das usinas brasileiras, sendo estas mais produtivas nos três insumos da análise de eficiência econômica: ativo operacional, despesas com mão-de-obra e custo do aço.
As a result of new market conditions, influenced by privatizations, crises and newcomers, the steel industry has sought the improvement of its management process, through production maximization and input optimization. In this context this dissertation aims to analyze the determining factors for the efficiency of Gerdau’s mini-mills, located in different countries of South and North America. This is a descriptive and exploratory study, with quantitative approach, based on data from the years 2009 and 2010. Case study was the procedure adopted, including 24 units of analysis. With the use of the Data Envelopment Analysis (DEA) methodology it was possible to measure the technical and economic efficiency of the selected mills, as well as to identify the benchmarks. The main findings show that the Brazilian mills are the most technically efficient; the relevant factors behind these results are their productivity in the safety incident input and low equipment downtime. A group of American mills was also considered technically efficient due to high productivity in the operational assets and labor inputs. By replacing the inputs for their relative prices, it becomes evident the superiority of the Brazilian mills in terms of result, which were more productive in the three economic efficiency analysis inputs: operational assets, administrative expenditure and costs of steelmaking.

Повний текст джерелаThe result of protracted and arduous negotiations, the United Nations Convention on the Law of the Seasigned in 1982 is undoubtedly one of the most successful multilateral treaties at the international level. The principle of the common heritage of mankind, represented by the seabed, ocean floor and subsoil and their resources beyond the limits of national jurisdiction, is the cornerstone of the Convention and constituted a major innovation in international law. The success of the Convention lies, in particular, in the establishment of an unprecedented institutional framework, which is incarnated by three institutions: the International Seabed Authority, the Commission on the Limits of the Continental Shelf and the International Tribunal for the Law of the Sea. These institutions of diverse legal status are vested with different functions and have been in operation since the entry into force of the Convention in 1994. Twentyone years following its establishment, it is necessary to review this institutional framework as a whole and to assess its implementation in order to better understand the complementary role of the institutions. This study critically examines the genesis, the nature, the functioning and the practice of the institutions throughtheir interaction and their interdependence. Identifying institutional and inter-institutional weaknesses, and the challenges that the institutions face is an indispensable prerequisite for ensuring effective and viablesolutions, the harmonious implementation of the Convention and for giving substance to the principle ofthe common heritage of mankind. In this context, the role of the Tribunal as the guarantor of the integrityof the Convention and the creative power of the international judge merit special attention

In this thesis, we propose a novel spatial data mining algorithm, called 9DSPA-Miner, to mine the spatial association rules from an image database, where every image is represented by the 9D-SPA representation. Our proposed method consists of three phases. In the first phase, we scan the database once and create an index structure. In the second phase, we scan the index structure to find all frequent patterns of length two. In the third phase, we use the frequent k-patterns (k≧2) to generate candidate (k+1)-patterns and check each generated candidate if its support is not less than the user-specified minimum support threshold by using the index structure. Then, the steps in phase 3 are repeated until no more frequent patterns can be found. Since 9DSPA-Miner uses the characteristics of the 9D-SPA representation to prune most of impossible candidates and the index structure to speed up the mining process, the experiment results demonstrate that it is more efficient and scalable than the modified Apriori method.

Повний текст джерелаAs the popularity of deep-sea mining beyond national jurisdiction grows amongst the international community, so does the need to assess whether or not humanity is moving too fast into something unknown and if the application of the Precautionary Principle is in order. Throughout this thesis we analysed the impacts of this activity and the evolution of its legal framework. We also focused on the Precautionary Principle, its core elements and determined whether or not there was cause for applying it to deep-sea mining. We found that there is, in fact, cause and that this Principle has already been included in some aspects of the legal framework of deep-sea mining beyond national jurisdiction. However, this inclusion is still insufficient and in order to build a legal framework based upon the Precautionary Principle, some necessary measures are still missing.

Tropical sea surface temperature (SST) data derived from the Geostationary Operational Environmental Satellite (GOES) is analyzed by using data mining to explore the error sources of data and to further improve its accuracy. The SST data has been pre-processed into two kinds of data set, the daily mean and hourly. The root mean square error (RMSE) of daily SST estimate is reduced from 0.58 K to 0.37 K and the mean absolute percentage error (MAPE) is 1.03% by using the Back Propagation Neural Network (BPN) algorithm. For the hourly SST estimate, its RMSE is also reduced from 0.66 K to 0.44 K and the MAPE is 1.1%. We also applied the decision tree algorithm to examine if the accuracy of GOES SST product can be improved. The results show that the RMSE and the MAPE are 0.47 K and 1.3%, respectively for daily dataset, and are 0.41 K and 1.0%, respectively for hourly dataset. This indicates that the BPN algorithm has a better ability of correction than that of decision tree algorithm. While the proportion of cloud contamination is in different circumstances, the RMSE of retrieval satellite SST by using the BPN algorithm can be maintained below 0.38 K. This demonstrated the efficiency ability of anti-noise analysis of the neural algorithm. The factor analysis also shows that the errors are mainly caused by air temperature and then followed by wind speed and relative humidity. From the analysis of classification rules, wind speed and relative humidity have significant classifying ability to access the characteristics of local climate. It indicates that the characteristics of local climate can affect the accuracy of SST derived from satellite infrared sensors. This study successfully demonstrates that the neural network algorithm can effectively reduce the SST error derived from GOES and the influent factors can be extracted by the decision tree algorithm.
