  1. 1. Flight strategies in migrating birds: when and how to fly

    Detta är en avhandling från Martin Green, Dept. of Animal Ecology, Ecology Building, S-223 62 Lund, Sweden

    Författare :Martin Green; Lund University.; Lunds universitet.; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; geese; waders; terns; Animal ecology; Djurekologi; wind tunnel; radio telemetry; satellite telemetry; radar; formation flight; flight speed adjustment; wind drift; energy savings; departure decisions; bird migration; wind;

    Sammanfattning : Wind has a profound influence on migrating birds since it inevitably will influence travel time and energy expenditure. In this thesis I investigate how migrating birds are affected by, and use winds. LÄS MER

  3. 2. Green Propellants

    Detta är en avhandling från Stockholm : KTH

    Författare :Martin Rahm; KTH.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Quantum chemistry; reaction kinetics; ammonium dinitramide; high energy density materials; rocket propellants; chemical spectroscopy; polymer synthesis; NATURAL SCIENCES Chemistry Theoretical chemistry Quantum chemistry; NATURVETENSKAP Kemi Teoretisk kemi Kvantkemi; NATURAL SCIENCES Chemistry Physical chemistry; NATURVETENSKAP Kemi Fysikalisk kemi;

    Sammanfattning : To enable future environmentally friendly access to space by means of solid rocket propulsion a viable replacement to the hazardous ammonium perchlorate oxidizer is needed. Ammonium dinitramide (ADN) is one of few such compounds currently known. LÄS MER

    Sammanfattning : This thesis deals with development of lean and green production systems from an action research point of view. The studies focus on Swedish-based automotive and vehicle industries and their aims to integrate sustainable thinking and environmental care into their operations management. LÄS MER

  7. 5. First principles methods for electronic structure calculations of solids

    Detta är en avhandling från Department of Theoretical Physics, Lund University

    Författare :Martin Springer; Lund University.; Lunds universitet.; [1997]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; screened interaction; T-matrix; vertex function; GW approximation; Green function; density functional theory; gradient expansion; order N method; Physics; Fysik;

    Sammanfattning : A straightforward gradient expansion of the exchange energy of a perturbed electron gas is performed. Studied perturbations range from very weak to those that produce, e.g., a silicon-like band structure with a band gap. LÄS MER
