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

    Author : Peng Zhang; Maria Strømme; Niklas Hedin; Uppsala universitet; []
    Keywords : mesoporous; magnesium carbonate; drug delivery; solubility enhancement; bioavailability; pharmacokinetics; diffusion release; controlled release; Teknisk fysik med inriktning mot nanoteknologi och funktionella material; Engineering Science with specialization in Nanotechnology and Functional Materials;

    Abstract : 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.

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

    Author : Peng Zhang; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diabetic health care; Multi-agent Systems; General Systems Theory; Activity Theory; reactivity; proactivity; social activity; Knowledge Engineering;

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

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

    Author : Peng Zhang; Göteborgs universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  7. 5. Oxidation behaviour of MCrAlX coatings : effect of surface treatment and an Al-activity based life criterion

    Author : Pimin Zhang; Ru Lin Peng; Xin-Hai Li; Sten Johansson; Fang Liu; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : MCrAlY coatings (M=Ni and/or Co) have been widely used for the protection of superalloy components against oxidation and hot corrosion in the hot sections of gas turbines. The drive to improve engine combustion efficiency while reducing emissions by increasing the operation temperature brings a big challenge for coating design. READ MORE
