2. 21. The neutron-induced fission cross section of 233Pa : and the quest for clean and safe nuclear energy

   Author : Fredrik Tovesson; Andreas Oberstedt; Dietrich Hilscher; Örebro universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik; fission; cross section; Pa-233; U-233; fysik; Physics; Fysik; Fysik; Physics;

   Abstract : Neutron-induced fission of 233Pa has been investigated between 1.0 and 8.5 MeV, and the reaction cross section was determined. Due to the short half-life of 233Pa for β-decay, fission events from the daughter product 233U affect the analysis of the protactinium experiment. READ MORE

4. 22. Cross-boundary knowledge work in innovation : Understanding the role of space and objects

   Author : Marta Caccamo; Karin Hellerstedt; Daniel Pittino; Sara Beckman; Robin Teigland; Jönköping University; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; cross-boundary knowledge work; knowledge management; knowledge sharing; knowledge integration; sociomateriality; boundary objects; affordances; material scaffolding; collaborative innovation; open innovation; business studios; corporate hackathons; startup accelerators;

   Abstract : This dissertation studies the topic of cross-boundary knowledge work from the perspective of sociomateriality. Cross-boundary knowledge work refers to the collaboration of actors belonging to different social worlds to achieve shared knowledge outcomes. READ MORE

5. 23. Surfactant Responsive Cross-Linked Polymer Hydrogels

   Author : Jesper Sjöström; Research Policy Institute (RPI); []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi; Two-step binding isotherms; Resolubilization; Nonmonotonic transient volume changes; Swelling isotherms; Divinyl sulfone DVS ; Polyquaternium; Cellulose ethers; Amphiphilic cross-linked polymers; Responsive gels; Polymer-surfactant interactions;

   Abstract : The focus of the thesis is on chemically cross-linked hydrogels which drastically change their volume when immersed in solutions of different ionic surfactants (with or without added salt). The two main questions addressed are: (1) How useful are simple gel swelling experiments to the study of polymer-surfactant interactions?, and (2) How does the volume of a cross-linked polymer gel change when it is immersed in a surfactant solution, both with respect to the equilibrium swelling and with respect to transient volume changes? Most of the gels studied were prepared by cross-linking linear polymers, which were well studied derivatives of hydroxyethyl cellulose (HEC). READ MORE

6. 24. Realizing the Single Software Market : Cross-National Validity of Software License Agreements

   Author : Jan Leidö; Johan Lindholm; Tom Madell; Lee Andrew Bygrave; Umeå universitet; []

   Abstract : The Internet has revolutionized the software industry, one of the world’s largest businesses. A single software market is emerging, independent of national borders, where products and services are digitally distributed. READ MORE

7. 25. A Cross-layered Pilot Scheme for IEEE 802.11p

   Author : Keerthi Nagalapur; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicular communications; FPGA implementation; Channel Estimation; Cross-layer; Pilot Scheme; IEEE 802.11p; OFDM;

   Abstract : Vehicular communication is expected to be a part of the future transportation system and promises to support a plethora of applications for traffic safety, traffic efficiency, and fuel efficiency. Traffic safety applications, such as collision avoidance, demand reliable communications with low latency. READ MORE
