Para medir o total de materiais particulados suspensos (PTS), um técnico usou um amostrador de grande volume (Hi-Vol). O filtro limpo pesou 15 g e a vazão inicial de ar passando era de 150 m3/h. Depois de 24 h o filtro sujo de particulado pesou 15,36 g e a vazão passando era de 90 m3/h. A concentração de particulados suspensos do ar é de

Uma bacia hidrográfica hipotética, com área de 7.200 km2, anualmente recebe 2.280 mm de chuva e infiltra 632 mm. A vazão média anual nessa bacia é de 100 m³/s. Sabendo-se que não existem perdas de água subterrânea para outras bacias e desprezando o volume interceptado, a evapotranspiração dessa bacia é de

Em uma seção transversal de um rio, a probabilidade de ocorrência de uma cheia catastrófica é de 25%. A probabilidade de que tal cheia ocorra nos próximos 5 anos é de

O projeto de um sistema de abastecimento de água adotou, para determinar a população a ser abastecida no horizonte de projeto, o método aritmético. Para efetuar os cálculos pesquisou os dois últimos censos populacionais do local. No ano de 2040, a população a ser abastecida, calculada segundo o método aritmético, será de

Um município muito acidentado topograficamente tem sua área habitada situada entre a cota topográfica de 520 m e a cota topográfica de 760 m. Sabendo-se que não existem problemas para o atendimento da pressão dinâmica mínima de 10 mca, assinale a opção que indica, no que diz respeito à pressão estática máxima, em quantas zonas de pressão com igual desnível deve ser subdividida a rede de distribuição de água municipal.

Um pequeno núcleo populacional rural de 240 habitantes resolveu utilizar, para o tratamento de suas águas servidas, um sistema composto por uma fossa séptica e um filtro anaeróbio invertido, atendendo ao prescrito nas NBR 13.969/97 e NBR 7.229/93. Considerando que a contribuição per capta é de 100 L/dia; o período de detenção dos esgotos “T” é de 0,75 dias; a taxa total de acumulação de lodo “K” de 57 dias e a contribuição de lodo fresco Lf é de 1 L/(hab.dia), o volume do filtro anaeróbio é de

Innovation is the new key to survival […] At its most basic, innovation presents an optimal strategy for controlling costs. Companies that have invested in such technologies as remote mining, autonomous equipment and driverless trucks and trains have reduced expenses by orders of magnitude, while simultaneously driving up productivity. Yet, gazing towards the horizon, it is rapidly becoming clear that innovation can do much more than reduce capital intensity. Approached strategically, it also has the power to reduce people and energy intensity, while increasing mining intensity. Capturing the learnings The key is to think of innovation as much more than research and development (R&D) around particular processes or technologies. Companies can, in fact, innovate in multiple ways, such as leveraging supplier knowledge around specific operational challenges, redefining their participation in the energy value chain or finding new ways to engage and partner with major stakeholders and constituencies. To reap these rewards, however, mining companies must overcome their traditionally conservative tendencies. In many cases, miners struggle to adopt technologies proven to work at other mining companies, let alone those from other industries. As a result, innovation becomes less of a technology problem and more of an adoption problem. By breaking this mindset, mining companies can free themselves to adapt practical applications that already exist in other industries and apply them to fit their current needs. For instance, the tunnel boring machines used by civil engineers to excavate the Chunnel can vastly reduce miners’ reliance on explosives. Until recently, those machines were too large to apply in a mining setting. Some innovators, however, are now incorporating the underlying technology to build smaller machines—effectively adapting mature solutions from other industries to realize more rapid results. Re-imagining the future At the same time, innovation mandates companies to think in entirely new ways. Traditionally, for instance, miners have focused on extracting higher grades and achieving faster throughput by optimizing the pit, schedule, product mix and logistics. A truly innovative mindset, however, will see them adopt an entirely new design paradigm that leverages new information, mining and energy technologies to maximize value. […] Approached in this way, innovation can drive more than cost reduction. It can help mining companies mitigate and manage risks, strengthen business models and foster more effective community and government relations. It can help mining services companies enhance their value to the industry by developing new products and services. Longer-term, it can even position organizations to move the needle on such endemic issues as corporate social responsibility, environmental performance and sustainability.

No século XX foi detectada, há dezenas de quilômetros abaixo da superfície terrestre, uma descontinuidade, chamada de Mohorovicic em homenagem ao seu descobridor. Essa descontinuidade é global e separa a crosta terrestre do manto, sendo a primeira composta por silicatos de baixa densidade e o manto formado por silicatos de alta densidade. Além do oxigênio, os elementos químicos mais abundantes na crosta terrestre, ordenados do maior para o menor percentual, são:

Como analista de participações, você é convidado a avaliar a possibilidade de entrada no capital de uma empresa nacional. Antes mesmo de analisar o balanço, sua primeira iniciativa é analisar a estrutura acionária dessa empresa de capital aberto para entender que tipos de sócios estão representados na estrutura de comando. Afinal, a visão de cada um desses sócios é o que determinará a estratégia da empresa. Ao realizar sua análise você se depara com vários sócios com interesses díspares e entre eles está a BlackRock Inc. A BlackRock é um dos maiores fundos de private equity do mundo. Esse tipo de fundo foi regulamentado no Brasil através da instrução CVM 391/03, e é denominado pela legislação:
