2. 1. Ultrastructural Studies of the Airway Epithelium in Airway Diseases

   Author : Eyman Shebani; Godfried M. Roomans; Marie Johannesson; Anil Mehta; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Morphology; asthma; cilia; corticosteroids; cytokines; desmosomes; Gaucher’s disease; montelukast; primary ciliary dyskinesia; transmission electron microscopy; Morfologi; Morphology; cell biology; pathology; Morfologi; cellbiologi; patologi;

   Abstract : Ultrastructural studies of airway epithelium in airway disease are important for diagnosis and understanding the underlying pathology which helps clinicians to improve the patients' treatment.Airway biopsies from a 5-month old boy with respiratory problems and gastro-oesophageal reflux were studied by transmission electron microscopy (TEM).

4. 2. Dendritic morphology and ultimate tensile strength of pearlitic lamellar graphite iron

   Author : Vasilios Fourlakidis; Attila Diószegi; Carlos A. Silva Ribeiro; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lamellar graphite iron; Primary austenite dendrite; Ultimate tensile strength; Microstructure model;

   Abstract : The continued development, of cylinder blocks and cylinder heads for heavy truck engines that are made of lamellar graphite iron (LGI) is focused on achieving high ultimate tensile strength (UTS) whilst conforming to environmental regulations. The purpose of this work is to further improve the tensile strength as well as the predictive engineering tools for optimization of LGI aimed to enhance the efforts for producing lighter and sustainable components without sacrificing performance.

5. 3. The role of primary austenite morphology in cast iron

   Author : Juan Carlos Hernando; Attila Diószegi; Arne Dahle; Jessica Elfsberg; Roberto Boeri; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solidification; Cast Iron; Primary Austenite; Microstructure Evolution; Coarsening; LGI; CGI; SGI; UTS; stelning; gjutjärn; primär austenit; mikrostrukturbildning; förgrovning; LGI; CGI; SGI; UTS;

   Abstract : Automotive industry products portfolio includes a wide variety of complex-shaped cast iron products, such as truck engine components. Urged by strict environmental regulations on emissions, these components constantly need to combine higher demands on performance with lighter designs. READ MORE

6. 4. Thermal Conductivity of Cast Iron: Influences of Microstructure on the Thermal Conductivity of Cast Iron

   Author : Daniel Holmgren; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EBSD; Laser Flash Technique; Modelling; Spheroidal Graphite; Lamellar Graphite; Primary Austenite; Compacted Graphite; Pearlite; Ferrite; Thermal Conductivity;

   Abstract : The thermal transport properties of cast iron are important in high temperature applications,where the temperatures should be kept low and the thermal gradients within the componentsmall. Dimensional and microstructural changes, thermally induced stresses and even failuremight be catastrophic consequences of intense and/or unevenly distributed temperatures. READ MORE

7. 5. Observations on morphology and function of cutaneous and subcutaneous sensory mechanoreceptors : an experimental study in mammals

   Author : Birgit Stark; Karolinska Institutet; Karolinska Institutet; []
   Keywords : mechanoreceptors; somatosensory organisation; blood-nerve barrier; Glucose transporter-1; nerve regeneration; TGF-ß family; neurotrophin receptors;

   Abstract : Tactile sensory discrimination is dependent upon an intact system of peripheral mechanoreceptors, their nerve fibre afferents with cell bodies in the dorsal root ganglion and the dorsal column-medial lemniscal system which relays tactile information from the skin to the cortex. Injury to any part of the afferent pathways leads to compromised mechanoreceptive perception. READ MORE
