  1. 1. A Numerical and Experimental Study of Airflow in Data Centers

    Författare :Emelie Wibron; T. Staffan Lundström; Jonathan Lewis Jonathan; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Airflow management is crucial for the performance of cooling systems in data centers. The amount of energy consumed by data centers is huge and a large amount is related to the cooling. In attempts to develop energy efficient data centers, numerical methods are important for several reasons. LÄS MER

  3. 2. Paleoglaciology of the Tian Shan and Altai Mountains, Central Asia

    Författare :Robin Blomdin; Arjen P. Stroeven; Clas Hättestrand; Jonathan M. Harbor; Lewis Owen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Paleoglaciology; glacial geomorphological mapping; cosmogenic nuclide dating; Tian Shan; Altai Mountains; Physical Geography; naturgeografi;

    Sammanfattning : The mountain-systems of Central Asia, act as barriers to atmospheric circulation patterns, which in turn impose striking climate gradients across the region. Glaciers are sensitive indicators of climate change and respond to changes in climate gradients over time by advancing during cold and wet periods and receding during warm and dry periods. LÄS MER

  4. 3. Catalytic Formation of Amides

    Författare :Fredrik Tinnis; Hans Adolfsson; Jonathan Williams; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organisk kemi; Organic Chemistry;

    Sammanfattning : The amide functionality is a highly important chemical bond, found in a great number of synthetic products such as pharmaceuticals, polymers and agrochemicals. The focus of this thesis has been directed towards efficient, mild and environmentally friendly methods for amide formations. LÄS MER
