   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power Tools; Nutrunners; Work Related Musculoskeletal Disorders; Risk Assessment; Load Exposure; Assembly Work; Monteringsverktyg; Mutterdragare; Arbetsrelaterade Muskuloskeletala Besvär; Riskbedömning; Belastningsexponering; Monteringsarbete; Teknik och hälsa; Technology and Health;

   Sammanfattning : Reaction force exposure from handheld tightening tools (also known as nutrunners) constitutes an acknowledged contributor to musculoskeletal disorders among assembly operators, and are today not regulated by explicit limits. The research presented in this thesis aimed at contributing to the development of recommended exposure limits for, and assessments of, reaction loads from handheld right-angle and pistol-grip tightening tools.

3. 2. 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

4. 3. New aspects of physical work load as a risk factor for musculoskeletal disorders

   Författare :Marketta Häkkänen; Göteborgs universitet; []
   Nyckelord :musculoskeletal disorder; upper limb; neck; shoulder; low back; physical work load; risk factor; job experience; trigger; interview; intervention; exposure assessment;

   Sammanfattning : ABSTRACT This study investigated new aspects of physical load factors as risk factors for musculoskeletal disorders among industrial employees. The following issues were in focus: the effect of physical work load and job experience on morbidity from musculoskeletal disorders, the incidence rates and induction times for these disorders, and the triggering factors for incident low back pain.

5. 4. Methods to assess physical load at work : With a focus on the neck and upper extremities

   Författare :Peter Palm; Mikael Forsman; Magnus Svartengren; Svend Erik Mathiassen; Eva Vingård; Esa Pekka Takala; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; risk assessment; physical load; upper extremities; ergonomics; Occupational and Environmental Medicine; Arbets- och miljömedicin;

   Sammanfattning : To prevent work-related musculoskeletal disorders (MSDs), useful, reliable and valid methods for assessing physical workload and risks for MSDs are needed. Ergonomists often assess work by short visual observations without a specific tool. LÄS MER

7. 5. Self-Healing Concrete

   Författare :Magdalena Rajczakowska; Andrzej Cwirzen; Karin Habermehl-Cwirzen; Hans Hedlund; Erik Schlangen; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cementitious materials; self-healing; exposure; fly ash; calcite; C-S-H; cracking; Byggmaterial; Building Materials;

   Sammanfattning : Concrete is a brittle material prone to cracking due to its low tensile strength. Crack repairs are not only expensive and time-consuming but also increase the carbon footprint. Designing a novel concrete material possessing the ability to self-repair cracks would enhance its sustainability. LÄS MER
