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

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

    Sammanfattning : 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.

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

    Författare :Henrik Lundgren; Per Gunningberg; Christian Tschudin; Marco Conti; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 3. Arenan och den entreprenöriella staden. Byråkrati, viljan att samverka och gåvans moraliska ekonomi

    Författare :Alexander Paulsson; Företagsekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Arena; Entrepreneurial City; Bureaucracy; Private-Public Collaboration; Governance; Gift;

    Sammanfattning : The Arena and the Entrepreneurial City builds on a microhistory of the collaboration between public and private organizations in the creation of two public sports arenas. Several new arenas have been built in Sweden during the last 15 years and many of them have received a lot of attention because of cost overruns and design flaws. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  7. 5. Vem har och tar ansvar! : – I Väntan På Ambulans (IVPA)-uppdrag i Glesbygdsmiljö

    Författare :Helena Nord-Ljungquist; Johan Berlin; Linnéuniversitetet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alarm call; Ambulance staff; Callers; Caring science; CPR; Emergency care; Emergency medical dispatcher; Evaluation; Firefighters; Lived experiences; T-CPR; Vårdvetenskap; Caring Science;

    Sammanfattning : Aim: The overall aim was to explore and describe experiences from the perspective of different actors in While Waiting for Ambulance (WWFA) assignments in a rural environment. The four studies aimed: to describe WWFA and ambulance assignments in rural environments, focusing on frequency, event time and actions of firefighters before an ambulance arrives at the scene, and to evaluate these actions (I); to describe emergency situations involving  WWFA assignment in a rural environment from the caller´s perspective (II); to describe compliance with the telephone-assisted cardiopulmonary resuscitation (T-CPR) protocol, the performance of the laypersons in a simulated T-CPR situation, and the communication between laypersons and EMDs during these actions (III); to describe WWFA assignment in a rural environment from the firefighters’ and the ambulance staff’s perspective (IV).
