   Författare :Brenda Vidal; Annelie Hedström; Inga Herrmann; Günther Langergraber; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainable sanitation; sand filter; phosphorus filter; package plant; cold climate; treatment process; system analysis; sustainability indicators; decentralization; centralization; historical development; on-site; resource recovery; source separation; source-separating systems; blackwater; urine; greywater; hållbarthetsanalys; små avlopp system; enskilda avlopp; markbädd; minireningsverk; kallt klimat; systemanalys; fosforfälla; fosforfilter; indikator; urin sortering; svartvatten; toalettvatten; gråvatten; BDT; VA-teknik; Urban Water Engineering;

   Sammanfattning : Current socio-technical wastewater system paradigms are being challenged by emerging global issues such as climate change, environmental degradation and scarcity of resources. Thus, exploration of innovative new urban water management solutions is required that enable closure of resource loops. LÄS MER

3. 2. Maternal and Neonatal Death Review System to Improve Maternal and Neonatal Health Care Services in Bangladesh

   Författare :Animesh Biswas; Koustuv Dalal; Fazlur Rahman; Charli Eriksson; Ragnar Westerling; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bangladesh; Facility Death Review; Maternal and Neonatal Health; Social Autopsy; Verbal Autopsy; Folkhälsovetenskap; Public health;

   Sammanfattning : Bangladesh has made encouraging progress in reducing maternal and neonatal mortality over the past two decades. However, deaths are much higher than in many other countries. The death reporting system to address maternal, neonatal deaths and stillbirths is still poor. LÄS MER

4. 3. On the Optimisation and Regulation of Clinical Trials

   Författare :Sebastian Jobjörnsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; decision theory; Bayesian statistics; optimal stopping.; clinical trials; subgroup analysis; drug regulation;

   Sammanfattning : The basic premise of this thesis is that Bayesian Decision Theory (BDT) can and should be used to solve clinical trial design problems. While the flexibility of the framework allows for accommodating a great variety of situations, it also requires an explicit consideration of the gains and costs associated with the trial. LÄS MER

5. 4. Reduction of refining energy during mechanical pulping : using pressurised chip compression and sulphite pre-treatment

   Författare :Erik Nelsson; Geoffrey Daniel; Mittuniversitetet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Chip pre-treatment; double disc refiner; energy efficiency; Impressafiner; low dosage; Norway spruce; refining intensity; single disc refiner; sulphite pre-treatment; thermomechanical pulp;

   Sammanfattning : The effects of pressurised compressive chip pre-treatment and low dosage sulphite pre-treatment were evaluated for production of thermomechanical pulp in mill scale trials using Norway spruce (Picea abies) at the Braviken paper mill (Holmen Paper AB, Sweden). The general aim of the study was to improve the energy efficiency during the production of mechanical pulps suitable for news and improved news grade papers. LÄS MER

7. 5. Nanoparticle Self-assembly on Prefabricated Nano Strucutres

   Författare :Johnas Eklöf; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanofabrication; Nanoparticles; single molecular electronics; Self-assembly;

   Sammanfattning : The demand for more powerful computers have been increasing ever since the first semiconducting devices were invented in the second half of the 20th century. The demand for an increase in computing power have escalated since the start of modern computer technology, however conventional techniques are reaching the limits regarding the downscaling of semiconducting based logic circuits.
