  2. 1. Process Integration of Industrial Heat Pumps in Grass-Root and Retrofit Situations

    Author : Erik Wallin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process integration; pinch technology; retrofit; industrial heat pumps; grass-root;

    Abstract : In several works, methods for process integration of heat pumps (HPs) have been developed, which in turn have been used for case studies in different industrial types. HP integration has thus proven to be a promising technique for utility savings and attractive payback periods. READ MORE

  4. 2. To Have and to Hold: Continuity and change in property rights institutions governing water resources among the Meru of Tanzania and the BaKgatla in Botswana; 1925-2000

    Author : Ellen Hillbom; Ekonomisk-historiska institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; institutional change; Botswana; institutions; Kgatleng; Meru; natural resources; property rights; Tanzania; Sub-Saharan Africa; water; Social and economic history; Ekonomisk och social historia;

    Abstract : Allocation, control, and management of natural resources are issues that absorb researchers within both the social and natural sciences. This study deals with such research questions as well as with one of the most fundamental issues in Economic History – namely institutional change. READ MORE

  5. 3. Optimum Design of Heat Exchanger Networks in Retrofit Situations

    Author : Annika Carlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimum design; pressure drop; process integration; pinch thechnology; heat transfer coefficients; heat exchanger networks; retrofit;

    Abstract : Today, the most important activity in heat exchanger network synthesis is the retrofitting, rather than grass-root design, of networks. There is a vast potential for energy improvement in many processes by increasing the level of internal heat exchange. READ MORE

  6. 4. Dangerous Liaisons : Why Ex-Combatants Return to Violence. Cases from the Republic of Congo and Sierra Leone

    Author : R. Anders Nilsson; Thomas Ohlson; Kristine Höglund; Mats Hammarström; Joanna Spear; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ex-combatants; reintegration; demobilization; DDR; conflict resolution; peacebuilding; civil wars; Republic of Congo; Sierra Leone; Peace and conflict research; Freds- och konfliktforskning;

    Abstract : After disarming and demobilizing, why do some ex-combatants re-engage in organized vio-lence, while others do not? Even though former fighters have been identified as a major source of insecurity in post-civil war societies due to their military know-how, there have been few efforts to systematically examine this puzzle. This study fills this research gap by comparing the presence or absence of organized violence in different ex-combatant communi-ties – all the former fighters that used to belong to the same armed faction and who share a common, horizontal identity based on shared war-and peacetime experiences.

  7. 5. Education for All in Sri Lanka : ICT4D Hubs for Region-Wide Dissemination of Blended Learning

    Author : Peter Mozelius; Henrik Hansson; Sutinen Erkki; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ICT4D; ICT4D hubs; Digital divide; Sri Lanka; Blended learning; Education for All; Computer and Systems Sciences; data- och systemvetenskap;

    Abstract : ICT4D, here defined as the use of Information and Communication Technologies (ICT) in developing regions, can be seen as one of the most powerful and cost efficient ways to improve the standard of living in the developing world. Many regions in Asia have shown a rapid but heterogeneous development where information technology had a drastic impact on development but often with the problems related to ICT4D 1. READ MORE
