  1. 1. Mesoporous magnesium carbonate as a drug delivery vehicle for stabilising amorphous drugs and regulating their release rate

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Peng Zhang; Uppsala universitet.; [2016]
    Nyckelord :mesoporous; magnesium carbonate; drug delivery; solubility enhancement; bioavailability; pharmacokinetics; diffusion release; controlled release;

    Sammanfattning : In today’s drug discovery, the number of candidate drugs based on new molecular entities with poor aqueous solubility is increasing. Since poor aqueous solubility of an active pharmaceutical ingredients (APIs) is associated with low bioavailability and thus limite their therapeutic effect, this is often a great challenge in the development of new drugs when oral administration is the preferred route of administration.

  2. 2. Multi-agent Systems in Diabetic Health Care

    Detta är en avhandling från Karlskrona : Blekinge Institute of Technology

    Författare :Peng Zhang; Blekinge Tekniska Högskola.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diabetic health care; Multi-agent Systems; General Systems Theory; Activity Theory; reactivity; proactivity; social activity; Knowledge Engineering;

    Sammanfattning : This thesis discusses how Multi-agent Systems (MAS) should be designed in the context of diabetic health care. Three fields are touched: computer science, socio-psychology and systems science. Agent Technology is the core technology in the research. LÄS MER

  3. 3. Multi-Agent Systems Supported Collaboration in Diabetic Healthcare

    Detta är en avhandling från Karlskrona : Blekinge Institute of Technology

    Författare :Peng Zhang; Blekinge Tekniska Högskola.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Multi-agent Systems MAS ; agent architecture; coordination; Diabetic healthcare collaboration; Activity Theory; holistic; hierarchy;

    Sammanfattning : This thesis proposes a holistic and hierarchical architecture to Multi-agent System design, in order to resolve the collaboration problem in diabetic healthcare system. A diabetic healthcare system is a complex and social system in the case that it involves many actors and interrelations. LÄS MER

  4. 4. Summer Climate Variability during the Past 1200 Years in Central Scandinavia – A Tree-Ring Perspective

    Detta är en avhandling från Karlskrona : Blekinge Institute of Technology

    Författare :Peng Zhang; Göteborgs universitet.; Gothenburg University.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Central Scandinavia; climate variability; dendroclimatology; maximum latewood density; Medieval Climate Anomaly; model-proxy data comparison; Pinus sylvestris L.; temperature; tree-ring width;

    Sammanfattning : To set the current 20th century warming in a long-term context, significant efforts have been made to reconstruct hemispheric-to-global temperatures beyond the instrumental period. Tree-rings, which have annual resolution and can be precisely dated, have been widely used to infer past climate variability. LÄS MER
