1. 6. Analysis of basic motor behaviors in quadrupeds

   Författare :Manideep Gupta Vemula; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Ability to perform locomotion in different directions and maintain upright body posture is crucial for normal life. At present, mice, which allows employing genetic approaches, are widely used in studying the locomotor system. In these investigations different experimental setups are used to evoke locomotion.

3. 7. Wear mechanisms in sheet metal forming : Effects of tool microstructure, adhesion and temperature

   Författare :Anders Gåård; Pavel Krakhmalev; Jens Bergström; Ulf Olofsson; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Galling; sheet metal forming; wear; friction; adhesion; temperature; Materialteknik; Materials Engineering;

   Sammanfattning : The general trend in the car body manufacturing industry is towards low-series production and reduction of press lubricants and car weight. The limited use of lubricants, in combination with the introduction of high and ultrahigh-strength sheet materials, continuously increases the demands on the forming tools. LÄS MER

4. 8. Peripheral Regulation of Pain and Itch

   Författare :Elín Ingibjörg Magnúsdóttir; Malin C. Lagerström; George H. Caughey; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pain; itch; CGRP; TRPV1; mast cell; mast cell protease; mMCP4; mMCP6; CPA3; endothelin-1; compound 48 80; MRGPRX2; single-stranded oligonucleotide;

   Sammanfattning : Pain and itch are diverse sensory modalities, transmitted by the somatosensory nervous system. Stimuli such as heat, cold, mechanical pain and itch can be transmitted by different neuronal populations, which show considerable overlap with regards to sensory activation. LÄS MER

7. 10. Insights into wear and deformation of alternative binder hardmetals

   Författare :Lisa Toller-Nordström; Susanne Norgren; Ben Britton; Uppsala universitet; []
   Nyckelord :hardmetal; cemented carbide; alternative binders; steel turning; electron microscopy; electron diffraction; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

   Sammanfattning : This work presents new insights into how hardmetals with alternative binders as well as cobalt based references react to wear and deformation. The main focus has been on hardmetals for steel turning, but also on studying certain fundamental properties of the new binder materials. LÄS MER
