  1. 1. Neonatal water and heat exchange : The influence of environmental factors and infant maturity

    Författare :Gunnar Sjörs; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; Neonatal; transepidermal water loss; respiratory water loss; radiant heat; heat exchange; water loss; incubators; Pediatrik; Paediatric medicine; Pediatrisk medicin; pediatrik; Pediatrics;

    Sammanfattning : The environment provided by commonly used infant incubators, the effect of radiantheat and exposure to cold air on the exchange of water and heat between newborninfants and their environment, and the water loss through the skin of infants born at24-25 weeks of gestation were investigated. The evaporation of water from the skinwas measured by the gradient method. LÄS MER

  3. 2. On Business Exchange Activity : Activity Systems and Business Networks

    Författare :Frans Prenkert; Håkan Håkansson; Lars Halén; Lars-Gunnar Mattsson; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business studies; Företagsekonomi; Business studies; Företagsekonomi;

    Sammanfattning : Starting from an empirical study of a business firm’s problems with implementing an information system in its business activity, this thesis identifies a need to theoretically model and conceptually develop the general business activity of a firm. This puts the context in focus, as a well-functioning information system needs to be anchored and developed to support and enhance the activities for which it is used, that is, contextualized.

  4. 3. Modification of Float Glass Surfaces by Ion Exchange

    Författare :Stefan Karlsson; Bo Jonson; Helmut Schaeffer; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ion exchange; float glass; surface modification; surface colour; flexural strength; Glasteknologi; Glass Technology;

    Sammanfattning : Glass is a common material in each person’s life, e.g. drinking vessels, windows, displays, insulation and optical fibres. By modifying the glass surface it is possible to change the performance of the entire glass object, generally known as Surface Engineering. LÄS MER
