   Sammanfattning : Paper packaging is commonly found in the form of paper and cardboard boxes, but recently paper packing is being used in food packaging, trays, beverage packaging and even paper straws, among others. Paper strength additives have been developed to increase the efficiency of the joint strength and the joint areas and potentially maintain bulk in paper products. LÄS MER

3. 2. Fluid Management in Haemodialysis : Studies on current practices and new methods

   Författare :Jenny Stenberg; Hans Furuland; Magnus Lindberg; Eva Tiensuu Janson; Bernd Stegmayr; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Haemodialysis; Fluid management; Fluid overload; Bioimpedance spectroscopy; Dry weight; Brain natriuretic peptide; Decision aid; Medicinsk vetenskap; Medical Science;

   Sammanfattning : Chronic fluid overload has been identified as an independent predictor of mortality in haemodialysis patients, and 30% remain fluid overloaded at dry weight. The use of bioimpedance spectroscopy (BIS) in fluid management may improve blood pressure control and cardiovascular status. LÄS MER

4. 3. Weight scaling : methods to determine the quantity of pulpwood

   Författare :Mikael Hultnäs; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Scaling pulpwood according to its weight for payment purposes is done in many places around the world. In North America, pulpwood is commonly scaled according to its green weight, while in Central Europe the wood is commonly scaled according to its dry weight. In Sweden pulpwood is measured according to its volume. LÄS MER

5. 4. Integration of filamentous fungi in ethanol dry-mill biorefinery

   Författare :Jorge Ferreira; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; airlift bioreactors; ascomycetes; biomass; bubble column; ethanol; feed; Neurospora intermedia; thin stillage; zygomycetes; Resursåtervinning; Resource Recovery;

   Sammanfattning : The industrial production of bioethanol as a replacement to gasoline is well-established worldwide, using starch- or sugar-rich substrates. Additionally, the bioethanol plants produce animal feeds derived from fermentation leftovers. The biorefinery character of bioethanol plants can be enhanced via process diversification. LÄS MER

7. 5. Occupant casualties in bus and coach traffic : injury and crash mechanisms

   Författare :Pontus Albertsson; Ulf Björnstig; Torbjörn Falkmer; Claes Tingvall; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; bus; coach; aerodynamics; crash; non-crash; cross-wind; injuries; weight distribution; road friction; restraints; haddons matrix; prevention; severe crash; mass casualty; major incident; alighting; boarding; incidents; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

   Sammanfattning : Background: The relevance of conducting this thesis is evident by the fact that bus and coach casualties have been “stubbornly stable” in Europe recent years and a need for investigating if a similar trend could be found in Sweden is therefore obvious. It was also important to add new knowledge to the bus and coach research in Sweden, since many areas were scarcely addressed. LÄS MER
