1. 1. A Method for Designing Resilient Digital Business Ecosystems

   Författare :Chen Hsi Tsai; Janis Stirna; Jelena Zdravkovic; Irina Rychkov; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; digital business ecosystem; method engineering; enterprise modelling; resilience; data- och systemvetenskap; Computer and Systems Sciences;

   Sammanfattning : Organisations and companies are transforming their ways of conducting business by combining digitalisation and digital collaboration in digital business ecosystems (DBE) in order to be able to remain competitive in global markets. However, for companies and organisations to be able to take full advantage of such collaborative business constellations, several challenges, including the capture and coordination of information concerning individual DBE actors and various perspectives of a DBE and the design of resilience for a DBE, need to be addressed.

3. 2. Parathyroid hormone-related protein (PTHrP), calcium and human osteoblast-like cells

   Författare :Jon A Tsai; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :hOB cells; PTHrP; cAMP; IGFs; IGFBPs; IL-1ß; TGF-ß; [Ca 2 ]i; [Ca2 ]O;

   Sammanfattning : Parathyroid hormone-related protein (PTHrP) may cause humoral hypercalcernia of malignancy (HHM) when overproduced by malignant tumors, but is also produced in lower amounts under normophysiological conditions in practically all cell types, including osteoblasts. One of the aims of the present study was to investigate interactions between PTHrP and osteoblasts, to elucidate bone-regulating functions of PTHrP. LÄS MER

4. 3. Approximations of Integral Equations for WaveScattering

   Författare :Andreas Atle; Björn Engquist; Richard Tsai; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Integral equations; Marching on in time; On surface radiation condition; Physical Optics; Numerical analysis; Numerisk analys;

   Sammanfattning : Wave scattering is the phenomenon in which a wave field interacts with physical objects. An incoming wave is scattered at the surface of the object and a scattered wave is produced. Common practical cases are acoustic, electromagnetic and elastic wave scattering. LÄS MER

5. 4. Treatment of subacromial pain and rotator cuff tears

   Författare :Hanna Cecilia Björnsson Hallgren; Lars Adolfsson; Kajsa Johansson; Rolf Norlin; Li Tsai-Fällender; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Shoulder; rotator cuff tear; ultrasound; surgery; exercises;

   Sammanfattning : Shoulder pain is very common, affecting 14-21 % of the population at some time during their lifetime. The aims of this thesis were to improve the understanding of various aspects concerning the pathogenesis and treatment of subacromial pain and rotator cuff tears. LÄS MER

7. 5. Non-Standard Crystallography : Examples in 3- and 3+1 Dimensional Space

   Författare :Jeppe Christensen; Sven Lidin; An-Pang Tsai; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Modulation; Crystallography; intermetallic; materials; Chemistry; Kemi; strukturkemi; Structural Chemistry;

   Sammanfattning : Crystallography today is by many seen as merely a tool for determining the structure of a material on the atomic level. It is expected that whatever comes out of the tool is the indisputable truth, a fact. This thesis is based on five publications illustrating that this is very far from the real world of materials research. LÄS MER
