  1. 1. Microalgae - future bioresource of the sea?

    Detta är en avhandling från Växjö : Linnaeus University Press

    Författare :Martin Olofsson; Linnéuniversitetet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microalgae; algal cultivation; bioresource; bioenergy; CO2 mitigation; multi-species community approach; seasonal variation; Akvatisk ekologi; Aquatic Ecology; Bioteknik; Biotechnology; Environmental technology; Miljöteknik;

    Sammanfattning : Unicellular microalgae are a renewable bioresource that can meet the challenge forfood and energy in a growing world population. Using sunlight, CO2, nutrients,and water, algal cells produce biomass in the form of sugars, proteins and oils, allof which carry commercial value as food, feed and bioenergy. LÄS MER

  2. 2. Systems Modeling Approaches to Physical Resource Management An Industrial Ecology Perspective

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Rajib Sinha; KTH.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Complex systems modeling; environmental accounting and monitoring; en- vironmental footprint; industrial ecology; pressure-based driver-oriented approach; Modellering av komplexa system; miljöräkenskaper och miljöövervakning; miljöpåverkan; industriell ekologi; flödesbaserad övervakningaktörsorienterad strategi; Industriell ekologi; Industrial Ecology;

    Sammanfattning : Many of the present problems that we are facing arise as unanticipated side-effects of our own actions. Moreover, the solutions implemented to solve important problems often create new problems. To avoid unintended consequences, understanding complex systems is essential in devising policy instruments and in improving environmental management. LÄS MER

  3. 3. Invading Herbivory. Effects of the Golden Apple Snail (Pomacea canaliculata) in Asian Wetlands

    Detta är en avhandling från Nils Carlsson Värbyvägen 206, 230 40 Bara, Sweden

    Författare :Nils Carlsson; Lund University.; Lunds universitet.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; gastropoda; invasive species; golden apple snail; herbivory; wetland functioning; biodiversity; sustainable control; indigenous predators; size-dependent competitive ability; akvatisk ekologi; limnologi; Marinbiologi; limnology; Hydrobiology; aquatic ecology; marine biology;

    Sammanfattning : The South American golden apple snail (Pomacea canaliculata) was intentionally introduced to aquacultures in South East Asia to produce snails for human consumption, but the aquatic snails soon escaped and started to consume large amounts of rice seedlings. The aim of this thesis was to quantify the effects of this invasive herbivore on aquatic plants in natural wetlands since previous research has focused on effects of the snail in rice fields.

  4. 4. Beyond Waste Management Challenges to Sustainable Global Physical Resource Management

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Jagdeep Singh; KTH.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sustainable global physical resource management; global waste management; systems thinking; life cycle thinking; planning framework; global environmental justice; circular economy; Industriell ekologi; Industrial Ecology;

    Sammanfattning : Current physical resource management (PRM) was investigated in a global perspective in this thesis, to gain a deeper understanding of its implications in a sustainability perspective. In particular, the main challenges to the current PRM system and the kinds of systemic changes needed for sustainable PRM were examined. LÄS MER

  5. 5. The Karma of Products Exploring the Causality of Environmental Pressure with Causal Loop Diagram and Environmental Footprint

    Detta är en avhandling från Stockholm, Sweden : KTH Royal Institute of Technology

    Författare :Rafael Laurenti; KTH.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Products; Environmental Pressure; Causal Loop Diagram; Environmental Footprint; Industriell ekologi; Industrial Ecology;

    Sammanfattning : Environmental pressures from consumer products and mechanisms of predetermination were examined in this thesis using causal loop diagram (CLD) and life cycle assessment (LCA) footprinting to respectively illustrate and provide some indicators about these mechanisms. Theoretical arguments and their practical implications were subjected to qualitative and quantitative analysis, using secondary and primary data. LÄS MER
