Popular Abstract in Swedish Varje dag bildas ca en biljon nya blodceller i en vuxen person. Eftersom blodceller är relativt kortlivade sker denna nyproduktion ständigt. Alla dessa celler härstammar från en sorts cell, multipotenta blodstamceller. Genom en gradvis mognadsprocess, genereras röda blodkroppar (erytrocyter), vita blodkroppar (granulocyter, lymfocyter och monocyter) och blodplättar (troProliferation, differentiation, and survival of hematopoietic stem cells and multipotent progenitor cells are regulated by cytokines and cell-cell interactions. Kit ligand (KL) and Flt3 ligand (FL) have pleiotropic effects, promotes survival, but are nonredundant. Using myeloid progenitor cell lines and mouse bone marrow-derived Lin- progenitors, we demonstrate that inhibition of phophatidylinosit

The two nature reserves Benestads backar and Hagestad in Scania, southernmost Sweden, were surveyed for insect diversity during 2011 and 2012. Because current management plans for both reserves include a size expansion to increase the protective status also of adjacent areas, the aim of this survey was to derive a measure of current insect diversity in both reserves. These estimates can then be us

This contribution deals with the topic of transnationalism as it has developed in the humanities in the last two decades. The starting point for the reflections is the author's experiences over the course of two research projects in the years 1996 to 2003. "Musik baut Brücken?" seeks to highlight some of the definitions and difficulties of "transnationalism" which have become obvious in several de

A flexible method for six-degree-of-freedom combined vision/force control for interaction with a stiff uncalibrated environment is presented. An edge-based rigidbody tracker is used in an observer-based controller, and combined with a six-degree-of-freedom force- or impedance controller. The effect of error sources such as image space measurement noise and calibration errors are considered. Finall

Introduction: In a cold,wet, or windy environment, cold exposure can be considerable for an injured or ill person. The subsequent autonomous stress response initially will increase circulatory and respiratory demands, and as body core temperature declines, the patient’s condition might deteriorate. Therefore, the application of adequate insulation to reduce cold exposure and prevent body core cool

Popular Abstract in Swedish Den här avhandlingen beskriver olika experimentella metoder att framställa nanopartiklar med kontroll över storlek och sammansättning. En nanopartikel är en partikel som är mindre än 100 nanometer (1 nm är en miljondels millimeter). Utmaningen ligger i att partiklarna är såpass små. En nanopartikel förhåller sig ungefär storleksmässigt till en tennisboll som en tennisboThis thesis describes experiments performed using different methods to produce aerosol nanoparticles with control over size and composition. The process included differential mobility analyzers (DMAs) as size-selecting instruments and tube furnaces for particle synthesis. A method to estimate the degradation of the DMA performance from the ideal case for individual DMAs was proposed and tested ex

C-fibre neuropeptides, such as tachykinins and calcitonin-gene related peptide (CGRP), play an important role in neurogenic inflammation. The present work deals with five different aspects of the physiology and pharmacology of C-fibres. 1) Tachykinin receptor antagonists of peptide and non-peptide nature have been employed to identify the tachykinin receptors of the rabbit iris as NK1 and NK3 type
