  1. 1. Modeling for Quality and Safety in Biopharmaceutical Production Processes

    Författare :Karin Westerberg; Institutionen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process modeling; chromatography; quality by design; robustness; process control;

    Sammanfattning : To design efficient and safe biopharmaceutical production processes, understanding the process and how it is affected by changes in the process conditions is essential. Experimental data form the basis of this understanding which can be enhanced by modeling and simulations of the physical and chemical processes known to control the process. LÄS MER

  2. 2. Past environmental and climate changes in northern Tanzania : Vegetation and lake level variability in Empakaai Crater

    Författare :Maria Ryner; Karin Holmgren; Peter Kuhry; Lars-Ove Westerberg; Henry Lamb; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; palaeoecology; palaeolimnology; physical and societal factors; Holocene; Tanzania; Lake Emakat; Engaruka; Earth sciences; Geovetenskap; Physical Geography; geografi med naturgeografisk inriktning;

    Sammanfattning : This thesis presents palaeoenvironmental data from equatorial Africa covering two important time intervals; i) the warming period forming the Pleistocene/Holocene transition and ii) the last millennium. The Empakaai Crater, in northern Tanzania contains a lake from where sediment cores, spanning two time-slices 14.8-9. LÄS MER

  3. 3. Diatoms in Lake Duluti : Tracking Environmental Variability in Northern Tanzania during the Past 1000 Years

    Författare :Helena Öberg; Lars-Ove Westerberg; Karin Holmgren; Jan Risberg; Robert Marchant; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Paleolimnology; Tanzania; Diatoms; Climate change; Crater lake; Physical Geography; naturgeografi;

    Sammanfattning : The tropics are the regions which are least understood climatically and new data on past climate variability is necessary for reliable future modeling of climate change. This thesis contributes with new paleoenvironmental information from a small crater lake in northern Tanzania and provides an additional link between the integrated history of climate, environment and socioeconomic variability in tropical Africa.

  4. 4. Environmental Factors of Importance in Myasthenia Gravis : Emphasis on Physical Activity

    Författare :Elisabet Westerberg; Anna Rostedt Punga; Anne-Marie Landtblom; Chantal Tallaksen; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Myasthenia Gravis; MG subgroups; Environmental factors; Lifestyle; Physical activity; Exercise; Clinical Neurophysiology; Klinisk neurofysiologi;

    Sammanfattning : Myasthenia Gravis (MG) is an autoimmune disease caused by antibodies directed against proteins at the neuromuscular junction (NMJ). The disturbed neuromuscular transmission induces fatigable weakness in skeletal muscles. LÄS MER
