2. 16. Experimental vitreoretinal surgery in the rabbit eye - electrophysiology and morphology

   Author : Karin Gjörloff; Lund Oftalmologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oftalmologi; Ophtalmology; retinectomy; GFAP; PKC; rabbit; vitrectomy; focal laser photocoagulation; full-field electroretinography; multifocal electroretinography;

   Abstract : The field of vitreoretinal surgery has expanded greatly over the last decades. A continuous refinement of surgical methods and instruments has increased the number of treatable retinal disorders. Vitrectomy, retinectomy and laser treatment are all part of the modern surgical arsenal. READ MORE

   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chip curl; Chip flow; Chip segmentation; Computed Tomography; Damage modeling; Flow stress modeling; Machining; Spånkrökning; Spånflöde; Spånsegmentering; Datortomografi; Skademodelleringen; Modellering av Flytspänning; Bearbetning; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

   Abstract : Within the manufacturing of metallic components, machining plays an important role and is of vital significance to ensure process reliability. From a cutting tool design perspective, physics-based numerical modeling that can predict chip morphology is highly necessary to design tool macro geometry. READ MORE

5. 18. 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.

6. 19. Nano- and mesoscale morphology evolution of metal films on weakly-interacting surfaces

   Author : Bo Lü; Kostas Sarakinos; Peter Münger; Thomas Michely; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Thin films are structures consisting of one or several nanoscale atomic layers of material that are used to either functionalize a surface or constitute components in more complex devices. Many properties of a film are closely related to its microstructure, which allows films to be tailored to meet specific technological requirements. READ MORE

7. 20. Microstructure and Inclusion Characteristics in Steels with Ti-oxide and TiN Additions

   Author : Wangzhong Mu; Pär Jönsson; Keiji Nakajima; Casper Van der Eijk; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; intragranular ferrite; oxide metallurgy; inclusion engineering; titanium nitride; titanium oxide; inclusion size; heterogeneous nucleation; critical diameter; confocal laser scanning microscopy CLSM ; differential scanning calorimetry DSC ; continuous cooling transformation CCT diagram.; Materials Science and Engineering; Teknisk materialvetenskap;

   Abstract : Non-metallic inclusions in steels are generally considered to be detrimental for mechanical properties. However, it has been recognized that certain inclusions, such as Ti-oxide and TiN, can serve as potent nucleation sites for the formation of intragranular ferrite (IGF) in low-alloy steels. READ MORE
