  1. 1. Exploring Software Cost Estimation Inaccuracy

    Author : Ana Magazinius; Chalmers tekniska högskola; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; organizational politics; estimation inhibitors; project management; software cost and effort estimation; learning in organizations; informal use of estimates;

    Abstract : The inaccuracy of software cost estimates has for long been a source of frustration to software practitioners and cost estimation researchers. Despite huge efforts to improve this important practice, estimation accuracy is still low. This thesis uses empirical and theoretical evidence to investigate why this problem persists. READ MORE

  2. 2. Cyclooxygenase-2 inhibitors and knee prosthesis surgery

    Author : Andreas Meunier; Lars Good; Per Aspenberg; Tore Dalén; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Non-steroidal anti-inflammatory agents; administration dosage; Arthroplasty; knee replacement; Surgical blood loss; Surgery; Cyclooxygenase inhibitors; Cyclooxygenase inhibitors; Fracture healing; Isoxazoles; Postoperative pain; Pyrazoles; Sulfonamides; Surgery; Kirurgi;

    Abstract : Adverse effects of cyclooxygenase (COX) inhibitors on bone healing have previously been demonstrated in diaphyseal fracture models in animals. In spite of that, they are widely used as postoperative analgesics in orthopaedic surgery. After joint replacement, a bone repair process starts at the interface between bone and cement. READ MORE

  3. 3. Strain-assisted corrosion cracking and growth rate inhibitors

    Author : Andrey P Jivkov; Mekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; materialteknik; Mechanical engineering; Material technology; Materiallära; Stress intensity factor; Inhomogeneous materials; Crack evolution; Stress corrosion cracking; Moving boundary; hydraulics;

    Abstract : A model for evolution of cracks as a result of strain-assisted corrosion is presented. The considered cracks possess a realistic geometry, where the tip region is an integral part of the crack surface instead of being a singular point. This geometry is either implicitly defined or is a consequence of crack nucleation from surface irregularities. READ MORE

  4. 4. Biochemical conversion of biomass : hydrothermal pretreatment, by-product formation, conditioning, enzymatic saccharification, and fermentability

    Author : Dimitrios Ilanidis; Leif J. Jönsson; Carlos Martin; Björn Alriksson; Eulogio Castro; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lignocellulosic biomass; hydrothermal pretreatment; enzymatic digestibility; ethanolic fermentation; microbial inhibitors; conditioning;

    Abstract : Lignocellulosic residues have great potential as feedstocks for production of bio-based chemicals and fuels. One of the main routes is biochemical conversion, which typically includes pretreatment, enzymatic saccharification, microbial fermentation of sugars, and valorization of hydrolysis lignin.

  5. 5. Pancreatic Cancer. Experimental and Clinical Studies

    Author : David Ljungman; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pancreatic neoplasms; Proteasome inhibitors; Apoptosis; Intracellular signaling peptides and proteins; Epidermal growth factor receptor; Pancreaticoduodenectomy; Cost and cost analysis; Quality-adjusted life years; Copy number variations; Comparative genomic hybridization;

    Abstract : Background: Pancreatic cancer is one of the most lethal of known cancers and the only treatment with possibility of cure is surgery. The costs associated with treatment of pancreatic cancer are reputably high, both in terms of morbidity and financially. READ MORE
