  1. 1. The hidden life of plants : fine root dynamics in northern ecosystems

    Författare :Gesche Blume-Werry; Roland Jansson; Ann Milbau; Scott D. Wilson; Isla Myers-Smith; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Arctic; belowground; boreal; climate change; fine roots; heath; meadow; minirhizotron; permafrost; phenology; plant community; root biomass; root growth; root litter; root production; subarctic; tundra;

    Sammanfattning : Fine roots constitute a large part of the primary production in northern (arctic and boreal) ecosystems, and are key players in ecosystem fluxes of water, nutrients and carbon. Data on root dynamics are generally rare, especially so in northern ecosystems. LÄS MER

  2. 2. Mine production index: Development and application

    Författare :Amol Lanke; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; production Assurance program PAP ; Fuzzy analytical hierarchy process FAHP ; Mine production assurance MPA ; Bottleneck detection; Mine production index MPi ; Mining; Industrial engineering and economy - Other industrial engineering and economics; Industriell teknik och ekonomi - Övrig industriell teknik och ekonomi; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : Assuring production forms a crucial part of mining business profitability. Factors related to various mine operations, activities and business processes can threaten required/planned mine production. To address problems and ensure production level in mining, it is necessary to implement a mine production assurance program (MPA). LÄS MER

  3. 3. Modelling and Management of Uncertainty in Production Systems : from Measurement to Decision

    Författare :Károly Szipka; Andreas Archenti; Sten Dr. Bergstrand; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Precision engineering; Uncertainty modelling; Machin-ing system capability; Production Engineering; Industriell produktion;

    Sammanfattning : The advanced handling of uncertainties arising from a wide range of sources is fundamental in quality control and dependability to reach advantageous decisions in different organizational levels of industry. Es-pecially in the competitive edge of production, uncertainty shall not be solely object of estimation but the result of a systematic management process. LÄS MER

  4. 4. Production Disturbance Management - The role of technology and managerial approaches in creating resilient production systems

    Författare :Adriana Ito; Chalmers University of Technology; []
    Nyckelord :resilient systems; production disturbance; managerial approach; Industry 4.0; technology; management;

    Sammanfattning : We live in a time that makes it clear the need of creating resilient production systems. To do so, it is necessary to efficiently and effectively manage production disturbances. Nevertheless, manufacturing companies have a very hard time thriving in this context. Mainly due to production disturbances, half their manufacturing capacity goes unused. LÄS MER

  5. 5. Effects of dissolved humic matter on phytoplankton

    Författare :Jessica von Einem; Biologiska institutionen; []

    Sammanfattning : Water colour is currently increasing in thousands of lakes in the northern hemisphere due to an increased input of terrestrial dissolved organic carbon (DOC), and more specifically coloured disscolved humic matter (DHM). I studied how water colour affects the light climate in the epilimnion and, as a consequence, phytoplankton biomass, species composition and production in lakes in southern Sweden. LÄS MER
