    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; clinical psychology; psychosomatics; Psychiatry; meta-analysis; opioid dependence; RCT; naltrexone; prescribed drugs; maintenance treatment; methadone; withdrawal symptoms; benzodiazepine dependence; DSM-IV; Psykiatri; klinisk psykologi; psykosomatik;

    Sammanfattning : The thesis contains 4 papers, two clinical studies and two meta-analyses. In the BZD taper study (Paper I) 21 BZD dependent (DSM-IV) patients were included for a 10-day inpatient detoxification. The average defined daily dose (DDD) was 4.7 doses. LÄS MER

  3. 2. Empirical Studies on Economic and Financial Spillovers : Asymmetric Risk and Dependence Modeling

    Författare :Axel Hedström; Gazi Salah Uddin; Ali M. Ahmed; Ugur Soytas; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Spillovers; systemic risk; risk modeling; risk dependence; asymmetric risk; energy finance; Spillovers; systemisk risk; riskmodellering; risk påverkan; asymmetrisk risk; energifinans;

    Sammanfattning : Financial assets are volatile, and volatility becomes more intense in terms of size and rate of recurrence when markets are uncertain and growing rapidly. The fact that the recurrence rate increased during crisis periods, such as the IT bubble in the early 2000 and the global financial crisis that started in 2007, is a key finding in the literature.

  4. 3. Influences of Statistical Analyses on Result Presentations of Oral Implant Treatment

    Författare :Irene Herrmann; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Statistical methods; oral implants; dependence; prognostic risk factors; multivariate analysis; bone-combination; Jackknife; log rank test; variance;

    Sammanfattning : Abstract Evaluation of oral implants involves at least three major components: statistical methods, study design and success criteria. The aims of the current thesis were to investigate how different statistical methods affect the outcome of oral implant treatment and to statistically determine if any dependence among implants placed in the same jaw exists.

  5. 4. On modelling of slope stability in sensitive clay

    Författare :Carolina Sellin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; constitutive modelling; mobilisation of shear strength; destructuration; slope stability; anisotropy; sensitive clay; rate dependence;

    Sammanfattning : The stability of natural slopes is a global problem, with the number of landslides and the associated socioeconomic losses increasing, as a result of the global trend of urbanisation, deforestation and changed weather patterns. The available methods for identifying potential failure modes and assessing the stability, however, overly simplify the modelled soil behaviour within a slope, which might lead to unnecessary mitigation measures or non-conservative results.

  7. 5. Failure of thin-walled structures under impact loading

    Författare :Salar Mostofizadeh; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shells; rate dependence; Phantom node method; cohesive zone; Continuum damage; XFEM; ductile fracture;

    Sammanfattning : Increase in computational power during recent years contributed to a significant development in numerical methods in mechanics. There are many methods developed that address various complex problems, yet modelling of initiation and propagation of failure in thin-walled structures requires further development. LÄS MER
