  1. 1. Methods for measuring physical workload with relevance for musculoskeletal disorders of neck and upper limb

    Författare :Gert-Åke Hansson; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; shoulder; exposure-response relation; exposure; repetitiveness; movements; postures; questionnaire; EMG; electromyography; accelerometer; Goniometer; inclinometer; arm; wrist; hand.; Occupational health; industrial medicine; Yrkesmedicin; arbetsmiljömedicin;

    Sammanfattning : Work-related musculoskeletal disorders of the neck and upper limb are a major problem. Women in repetitive manual work is one large affected group. Preventive actions are hampered by the lack of knowledge regarding quantitative exposure-response relations for physical workload. LÄS MER

  3. 2. Image-based quantitative infrared analysis and microparticle characterisation for pulp and paper applications

    Författare :Kari Hyll; Lars Mattsson; Hannes Vomhoff; Samuel Schabel; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metrology; stock; papermaking; refining; fibrillation; fines; filler; morphology; classification; flow microscopy; fibre analyser; flow cytometry; laser diffraction; dynamic image analysis; process variation; thermography; emittance; emissivity; infrared; MWIR; LWIR; goniometer; Production Engineering; Industriell produktion; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Measurements of process variations and particle morphology are widely employed in the pulp and paper industry. Two techniques with high potential, infrared thermography and microparticle characterisation, are mainly used qualitatively. LÄS MER

  4. 3. Development of rotation electron diffraction as a fully automated and accurate method for structure determination

    Författare :Bin Wang; Xiaodong Zou; Andy Stewart; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electron crystallography; structure determination; structure refinement; metal-organic framework; guest molecules; software development; automation; hierarchical cluster analyses; high-throughput data processing; data merging; frame orientations; least-squares optimization; data processing; TEM goniometer; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : Over the past decade, electron diffraction methods have aroused more and more interest for micro-crystal structure determination. Compared to traditional X-ray diffraction, electron diffraction breaks the size limitation of the crystals studied, but at the same time it also suffers from much stronger dynamical effects. LÄS MER

  5. 4. Wrist and thumb joint postures and motions: Measurements using electrogoniometry and EMG

    Författare :Per Jonsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Wrist joint; Finger joint; Electromyography; Accuracy; Electrogoniometry; Input device; Information and communication technology; Mobile phone; Muscle activity; Posture; Thumb; Wrist;

    Sammanfattning : Correct measurements of the joints’ extreme postures, velocity and repetitiveness are important for studies of the origin of musculoskeletal disorders. Posture measurements of wrist and thumb joints may also provide insights into input device designs that may reduce effort and/or facilitate productivity. LÄS MER

  7. 5. Some studies in nuclear structure by coincidence measurements

    Författare :Benny Sundström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The coincidence technique is a basic method for determining nuclear parameters.From single and coincidence gamma-ray measurements, using high resolution Ge(Li) detectors, a level scheme of 123Sb was determined. LÄS MER
