1. 26. A Co-Simulation Tool Applied to Hydraulic Percussion Units

   Författare :Håkan Andersson; Daniel Leidermark; Kjell Simonsson; Joakim Holmberg; Pär Jonsén; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : In this dissertation, a co-simulation tool is presented that is meant to comprise a more comprehensive environment for modelling and simulation of hydraulic percussion units, which are used in hydraulic hammers and rock drills. These units generates the large impact forces, which are needed to demolish concrete structures in the construction industry or to fragment rock when drilling blast holes in mine drifting. LÄS MER

3. 27. Turbulence Descriptors in Arterial Flows : Patient-Specific Computational Hemodynamics

   Författare :Magnus Andersson; Matts Karlsson; Jonas Lantz; Tino Ebbers; Kristian Valen-Sendstad; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : At this very moment, there are literally millions of people who suffer from various types of cardiovascular diseases (CVDs), many of whom will experience reduced quality of life or premature lift expectancy. The detailed underlying pathogenic processes behind many of these disorders are not well understood, but were abnormal dynamics of the blood flow (hemodynamics) are believed to play an important role, especially atypical flow-mediated frictional forces on the intraluminal wall (i.

4. 28. On the role of the retinoblastoma tumor suppressor gene in hematopoietic differentiation

   Författare :Gösta Bergh; Helsingborg Kliniska Vetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antisense; leukemia; cell cycle; differentiation; hematopoiesis; p16; p53; tumor suppressor genes; RB; oligonucleotides; Haematology; extracellular fluids; Hematologi; extracellulära vätskor;

   Sammanfattning : The aim of this study was to investigate the role of some tumor suppressor gene products (with emphasis on the retinoblastoma suppressor gene product) in the regulation of differentiation and proliferation in leukemic and normal hematopoietic cells. For this purpose, the expression of the tumor suppressor genes RB, p53 and p16 were artificially altered. LÄS MER

5. 29. Negative Pressure Wound Therapy - Mechanisms of Action and Protecting Exposed Blood Vessels in the Wound Bed

   Författare :Erik Anesäter; Thoraxkirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Negative pressure wound therapy; wounds; complications; experimental surgery; blood flow;

   Sammanfattning : NPWT has recently been associated with severe complications and bleeding when used in wounds with exposed blood vessels. The aims of this work were to investigate the mechanisms of action of NPWT and to explore the possibility of using thin plastic discs to protect exposed blood vessels in the wound bed during NPWT.

7. 30. Protection of Biomolecules by Antioxidants - Mechanisms and Applications

   Författare :Carl Grey; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dG; antioxidants; mass spectrometry; Analytical chemistry; Analytisk kemi; Food and drink technology; Livsmedelsteknik; Bioteknik; Biotechnology; DNA; Oxidation; Protein; Fenton reaction;

   Sammanfattning : Reactive oxygen species (ROS) consisting of various oxygen-based free radicals as well as other reactive non-radical species produced in O2-related metabolism or through other processes are involved in the oxidation of such vital biomolecules as DNA, proteins and lipids. The types of oxidation represented here are known to cause many different diseases and disorders in human beings, such as cancer, Alzheimer's disease and ageing. LÄS MER
