1. 1. Malleus fracture : experimental and clinical aspects

   Författare :Anders Niklasson; Krister Tano; Magnus Von Unge; Preben Homøe; Umeå universitet; []
   Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; malleus fracture middle ear human temporal bone laser doppler vibrometry; Oto-Rhino-Laryngology; oto-rhino-laryngologi;

   Sammanfattning : Background: Patients with malleus fractures are described as rare in the literature. The cause of these fractures are most commonly trauma and digital manipulation of the ear canal, while in some cases the causes are unknown. LÄS MER

3. 2. Experimental studies on fracture healing. Biological and biomechanical aspects

   Författare :Hans Mark; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
   Nyckelord :fracture; intramembranous; endochondral; ossification; neovascularization; fracture fixation; fracture stability;

   Sammanfattning : Considerable advances have been made in the knowledge regarding fracture healing and treatment duringrecent decades. Nevertheless, in 5-10 per cent of fractures, there are healing complications leading to complextreatment conditions, discomfort for patients and considerable costs. LÄS MER

4. 3. The influence of alcohol on bone metabolism and fracture healing

   Författare :Fredrik Nyquist; Malmö Institutionen för kliniska vetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kirurgi; traumatology; orthopaedics; Surgery; fracture prediction.; fracture healing; bone mineral density; Alcohol; post-traumatic osteopenia; fracture; ortopedi; traumatologi; Skeleton; muscle system; rheumatology locomotion; Skelett; muskelsystem; reumatologi;

   Sammanfattning : The influence of alcohol on bone metabolism, fracture and fracture healing was evaluated in men and male rats by measurements of bone mineral density (BMD), biochemical markers and biomechanical testings. Retrospectively, 199 male patients hospitalized for tibia shaft fractures were studied. Forty-nine were judged as problem drinkers. LÄS MER

5. 4. Mechanical behaviour of adhesive layers : experimental methods, cohesive laws, and fracture mechanics

   Författare :Anders Biel; Kristofer Gamstedt; Högskolan i Skövde; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; experimental method; adhesive layer; cohesive law; fracture; fracture energy; energy release rate; peel; shear; Materials science; Teknisk materialvetenskap; Teknik; Technology;

   Sammanfattning : Adhesive joining is today viewed as one of the key technologies to achieve decreased emissions in the automobile industry. To decrease weight, optimal material selection often results in different materials for different parts. This leads to the necessity to join mixed material. Here, the use of adhesives is the most promising joining technology. LÄS MER

7. 5. Constitutive Behaviour and Fracture of Adhesive Layers : Inverse Methods and Energetic Balance

   Författare :Svante Alfredsson; Högskolan i Skövde; []
   Nyckelord :adhesive layer; constitutive behaviour; fracture; energy release rate; shear fracture; mode-mixity; experimental method; inverse solution; multi-material joints; TECHNOLOGY; TEKNIKVETENSKAP; Teknik; Technology;

   Sammanfattning : In the automobile industry, current demands on reduced emissions with maintained or even increased crash worthiness, forces the industry to seek weight-reducing designs. The possibility to use lightweight materials is obviously attractive. At joints, these lightweight materials have to be connected to high-strength or low-cost materials. LÄS MER
