1. 1. Movement strategies and dynamic knee control after anterior cruciate ligament injury : a three-dimensional biomechanical analysis

   Författare :Jonas L. Markström; Charlotte K. Häger; Eva Tengman; Helena Grip; Lina Schelin; Jim Richards; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anterior cruciate ligament; biomechanics; kinematics; kinetics; finite helical axis; injury prevention; sports; reliability; agreement; one-leg hops; functional data analysis; physiotherapy; fysioterapi;

   Sammanfattning : Background: Rupture of the anterior cruciate ligament (ACL) is common and mainly occurs in non-contact situations in sports, often due to momentarily poor movement control. Assessment of movement quality during sport-like tasks iscrucial to understand how to decrease the high risk of reinjury for ACL-injured persons, but also how to prevent primary injury. LÄS MER

3. 2. Three Dimensional Determinations of Inclusions in Ferroalloys and Steel Samples

   Författare :Yanyan Bi; Andrey Karasev; Chris Pistorius; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Three dimensional; Ferroalloy; Inclusion; Spinel inclusion; T hermodynamic calculation; REM clusters; Formation mechanism; Statistical analysis; Maximum size;

   Sammanfattning : As the requirements on material properties increase, there has been a demand on an additional knowledge on the effect of impurities in the ferroalloyson the steel cleanness. Thus, the number, morphology, size and composition of inclusions in sixdifferent ferroalloys (FeTi, FeNb, FeSi,SiMn, LC and HC FeCr) were investigatedin this study. LÄS MER

4. 3. The three-dimensional normal-distributions transform : an efficient representation for registration, surface analysis, and loop detection

   Författare :Martin Magnusson; Achim Lilienthal; Wolfram Burgard; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NDT; 3D sensing; surface representation; registration; loop detection; surface analysis; mobile robotics; localisation; mapping; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

   Sammanfattning : This dissertation is concerned with three-dimensional (3D) sensing and 3D scan representation. Three-dimensional records are important tools in several disciplines; such as medical imaging, archaeology, and mobile robotics. LÄS MER

5. 4. Quiescent cancer cells : Three-dimensional cell models for evaluation of new therapeutics

   Författare :Frida Ek; Mårten Fryknäs; Malin Jarvius; Rolf Larsson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cancer; cancer cell quiescence; dormancy; three-dimensional; multicellular tumor spheroids; model development; cancer pharmacology; mitochondria; OXPHOS; colorectal carcinoma; hepatocellular carcinoma; Medicinsk vetenskap; Medical Science;

   Sammanfattning : Inadequate metabolic conditions in solid tumors lead to the formation of quiescent cancer cells that are suspended in a transient cell cycle arrest. When conditions change, quiescent cancer cells can re-enter the cell cycle and cause recurrence. LÄS MER
