  1. 1. Fighting for Aid : Foreign Funding and Civil Conflict Intensity

    Författare :Daniel Strandow; Magnus Öberg; Michael G. Findley; Kristian Skrede Gleditsch; Uppsala universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Aid; foreign aid; foreign assistance; relief; humanitarian; conflict; civil war; civil conflict; geographic concentration; intra-state; violence; military; contest; low-intensity; guerrilla; irregular; conventional; decision theory; contest success function; geo-coding; geo-referencing; territorial control; propensity score; Africa; South of the Sahara; Peace and Conflict Research; Freds- och konfliktforskning;

    Sammanfattning : This dissertation focuses on the sub-national impact of foreign aid on civil conflicts by asking the question: How does foreign aid committed to contested areas affect the intensity of violence in those areas? The main theoretical contribution is to focus on how aid influences warring parties’ decisions to engage in contests over territorial control and how that in turn influences violence intensity. The study introduces two concepts: funding concentration and barriers to exploiting aid. LÄS MER

  3. 2. Costa Rican coffee and bananas : A social-ecological study of management practices and their effects on the environment

    Författare :Angelina Sanderson Bellamy; Micheal Tedengren; Charles Francis; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Costa Rica; coffee; banana; production system; pesticides; organic; conventional; Rainforest Alliance certification; Biology; Biologi; marin ekotoxikologi; Marine Ecotoxicology;

    Sammanfattning : This thesis investigates the variability in management practices on coffee and banana farms in an attempt to identify practices that reduce the environmental impact of export crop production. Different banana production systems are studied to determine their level of environmental impact. LÄS MER

  4. 3. Conventional, microfilled and hybrid composite resins : laboratory and clinical evaluations

    Författare :Jan W. V. van Dijken; Torild Ericson; Umeå universitet; []

  5. 4. Downstream migration of salmonids in regulated rivers : Non-conventional methods for fish diversion

    Författare :Johan Leander; Jonatan Klaminder; Micael Jonsson; Gustav Hellström; Paul Kemp; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Fish migration; Fish passage; Fish guidance; Hydropower; Atlantic salmon; Brown trout; Bubble barrier; Non-physical barrier;

    Sammanfattning : Passages through hydropower plants can be fatal for downstream migrating salmonids (Salmo spp.). This is particularly true for large adults that are returning to the ocean after spawning. LÄS MER

  7. 5. High volumetric machining strategies for superalloy gasturbine components : Comparing conventional and nonconventional machining methods for efficient manufacturing

    Författare :Jonas Holmberg; Johan Berglund; Anders Wretland; Tomas Beno; Joel Andersson; Sten Johansson; RISE; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Alloy 718; High volumetric machining; Conventional and Nonconventional machining; Material removal rate; Post processing; surface integrity; Residual stress; Microstructure; Deformation; Manufacturing; Surface and Joining Technology; Bearbetnings-; yt- och fogningsteknik; Production Technology; Produktionsteknik;

    Sammanfattning : There is a strong industrial driving force to find alternative manufacturing technologies in order to make the production of aero engine components of superalloys even more efficient than it is today. Introducing new and nonconventional machining technologies, as well as enhanced utilisation of today's high volumetric manufacturing, allows taking a leap to increase the material removal rate and the productivity.
