  2. 1. Evolution of New Genes and Functions

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Erik Lundin; Uppsala universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Abstract : To answer major evolutionary questions, we need a better understanding of the effects of mutations on specific functions and organism fitness. The aim of this thesis was to elucidate how new functions evolve and potential trade-offs with the original function. READ MORE

  4. 2. Uplink Load in CDMA Cellular Systems

    University dissertation from Linköping : Linköping University

    Author : Erik Geijer Lundin; Linköpings universitet.; Linköpings universitet.; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Code Division Multiple Access;

    Abstract : Cellular mobile systems designed to handle multimedia services are currently being developed. The primary goal for any mobile system is to provide a satisfactory quality of service, both to operators and customers.

  5. 3. Slow Transit Constipation Aspects of Diagnosis and Treatment

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Erik Lundin; Uppsala universitet.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; colectomy; constipation; radio-opaque markers; rectal compliance; rectal sensation; scintigraphy; segmental colonic resection; segmental colonic transit; sphincter pressure; Kirurgi; MEDICINE Surgery; MEDICIN Kirurgi;

    Abstract : Oral 111-Indium-DTPA colonic scintigraphy was used to assess segmental transit in 23 patients with slow transit constipation (STC) and 13 controls. The transit time did not differ between patients and controls in the right colon, whereas the patients had a consistent delay from the transverse colon and distally (P<0.05–0.001). READ MORE

  6. 4. The role of inland waters in the carbon cycle at high latitudes

    University dissertation from Umeå : Umeå universitet

    Author : Erik Lundin; Umeå universitet.; [2014]
