   Sammanfattning : This dissertation aims to generate an understanding of collective learning in social entrepreneurial organisations in Sweden, especially during the COVID-19 pandemic. Employing a collective learning-centred perspective, I want to explore the following key areas: a) the learning conditions and organising processes entailed in becoming a social entrepreneur and creating a social entrepreneurial organisation, b) the importance of collective learning for organisational adaptation and change in tackling exogenous factors such as the COVID-19 pandemic, and c) the role of leadership in creating conditions conducive to collective learning processes in social entrepreneurial organisations during the COVID-19 pandemic.

4. 13. Investigation of Thermal Performance of Cylindrical Heatpipes Operated with Nanofluids

   Författare :Morteza Ghanbarpourgeravi; Rahmatollah Khodabandeh; Björn Palm; Oronzio Manca; KTH; []
   Nyckelord :Nanofluid; heat pipe; thermal resistance; heat transfer coefficient; evaporator; condenser; wick; porous layer; heat flux; inclination angle; thermal conductivity; viscosity; Energiteknik; Energy Technology;

   Sammanfattning : Nanofluids as an innovative class of heat transfer fluids created by dispersing nanometre-sizedmetallic or non-metallic particles in conventional heat transfer fluids displayed the potential toimprove the thermophysical properties of the heat transfer fluids. The main purpose of this study is toinvestigate the influence of the use of nanofluids on two-phase heat transfer, particularly on thethermal performance of the heat pipes. LÄS MER

5. 14. Managing design rationale in the development of product families and related design automation systems

   Författare :Morteza Poorkiany; Fredrik Elgh; Joel Johansson; Jerzy Pokojski; Jönköping University; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design rationale; design automation system; computer-supported engineering design; product development;

   Sammanfattning : As the markets’ needs change rapidly, developing a variety of products that meet customers’ diverse needs is a competitive factor for many manufacturing companies. Development of highly customized products requires following an engineer-to-order business process to allow the products to be modified or adapted to new customers’ specifications, which brings more value to the customer and profit to the company.
