2. 1. Fibre/fibre joints : their characterization and influence on different paper strength properties

   Author : Annsofie Torgnysdotter; Lars Wågberg; Derek Gray; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; Kemiteknik;

   Abstract : The main goal of this work was to gain knowledge of how to process the fibres for a certain enduse purpose. To reach this knowledge it must be clarified how different fibre properties, mechanical and chemical as well as surface and bulk properties, will influence the physical properties of the formed paper.

4. 2. Implementation and Experimental Evaluation of Wireless Ad hoc Routing Protocols

   Author : Henrik Lundgren; Per Gunningberg; Christian Tschudin; Marco Conti; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; wireless ad hoc network; mobile ad hoc network; MANET; experimental evaluation; real world experiments; communication gray zone; gray zone; routing protocol; ad hoc networking; Computer science; Datavetenskap;

   Abstract : A wireless ad hoc network consists of a number of mobile nodes that temporarily form a dynamic infrastructure-less network. New routing protocols that can adapt to the frequent topology changes induced by node mobility and varying link qualities are needed. READ MORE

5. 3. Investigation on the Influence of Nodularity in Machining of Compacted Graphite Iron (CGI)

   Author : Gustav Grenmyr; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compacted Graphite Iron CGI ; cutting forces; wear mechanisms; tool wear; nodularity; tool temperature; cutting temperature;

   Abstract : Stringency of environmental legislation on emission rates and increasing vehicle performance requirements are pushing the automotive and heavy truck industries to find new solutions for their diesel engines. Two potential opportunities to address these challenges involve increased combustion pressure to obtain more efficient combustion or reducing the weight of the engine. READ MORE

6. 4. Laboring Through Uncertainty : an ethnography of the Chinese state, labor NGOs, and development

   Author : Darcy Pan; Johan Lindquist; Anette Nyqvist; Stephan Feuchtwang; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; uncertainty; intimacy; complicity; mingan; secrecy; state; NGO; socialantropologi; Social Anthropology;

   Abstract : This study sets out to understand how international development projects supporting labor activism work in contemporary China. It focuses on the lived experiences of and relationships among a group of grassroots⁠ labor NGOs in the province of Guangdong, South China; intermediary NGOs in Hong Kong; and Western funding agencies that try to bring about social change in postsocialist China where the political climate is still highly restrictive and the limits of the state’s tolerance for activism are ambiguous and uncertain.

7. 5. Modelling and Experimental Investigations on Thermal Radiation in Combustion Environments

   Author : Henrik Hofgren; Värmeöverföring; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal radiation; Property model; SNB; WSGG; LBL; Planck; particle; fly-ash; soot; grate; furnace; combustion;

   Abstract : Thermal radiation is an important physical phenomenon in combustion environments. For the understanding of existing- and the design of new combustion environments computational modelling is a useful tool as it can describe the different transport phenomena. READ MORE
