   Författare :Haochen Duan; Abigail Barker; Jaroslaw Majka; Stefan Wastegård; Kate Saunders; Susanne M. Straub; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Oceanic arc; Izu rear-arc; Melt inlcusions; Oxygen isotopes; Boron isotopes; Continental crust; Mantle hererogeneity; In-situ microanalysis; IMS-1280; Geovetenskap med inriktning mot mineralogi; petrologi och tektonik; Earth Science with specialization in Mineral Chemistry; Petrology and Tectonics;

   Sammanfattning : The Izu oceanic arc is produced by the subduction of the Pacific Sea Plate beneath the Philippine Sea Plate. The proto-Izu oceanic arc was initially formed at ca. 50 Ma, then it was separated into the Kyushu-Palau and Izu arc by the extension of the Shikoku basin from ca. 25 Ma. LÄS MER

3. 2. Silicon Carbide Reinforced Alumina and Mullite Ceramics

   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ceramic Nanocomposites; Creep; SEM; SiC; Grain Boundaries; Microanalysis; Mullite; Pressureless Sintering; TEM; Alumina;

   Sammanfattning : The aim of this work was to develop homogeneous ceramic nanocomposite materials with good thermal and structural stability as well as good mechanical properties. The development of microstructure was related to the material properties. LÄS MER

4. 3. Studies of the Elemental Composition of Airway Surface Liquid with Relevance to Cystic Fibrosis

   Författare :Viengphet Vanthanouvong; Godfried M. Roomans; Isabelle Sermet-Gaudelus; Uppsala universitet; []
   Nyckelord :Anatomy; airway surface liquid; cystic fibrosis; Na; K; Cl; X-ray microanalysis; Anatomi;

   Sammanfattning : Cystic fibrosis (CF) is an inherited disease with symptoms mainly in the respiratory tract. The airway epithelium is covered with a thin layer of fluid, the airway surface liquid (ASL). The volume and composition of ASL are important in the pathogenesis of cystic fibrosis. The composition of ASL was determined. LÄS MER

5. 4. Ion transport in exocrine glands with reference to cystic fibrosis

   Författare :Ailing Zhang; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; ion transport; cystic fibrosis; submandibular gland; airway submucosal gland; X-ray microanalysis; cytosolic Ca2 concentration; immunocytochemistry; Cellbiologi; Cell biology; Cellbiologi; Human Anatomy; anatomi;

   Sammanfattning : Aspects of ion transport in rat submandibular gland acinar cells at the subcellular level, and the regulation of chloride secretion and calcium mobilization in cultured pig tracheal gland acinar cells were studied with reference to the disease cystic fibrosis.In adult rat submandibular gland acinar cells, both cholinergic and α-adrenergic stimulation induced efflux of K+ and of C1-, but the response was generally less with α-adrenergic stimulation.

7. 5. The role of particles on initial atmospheric corrosion of copper and zinc : lateral distribution, secondary spreading and CO2-/SO2-influence

   Författare :Zhuo Yuan Chen; Christofer Leygraf; Jan-Erik Svensson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; atmospheric corrosion; copper; zinc; NaCl particles; NH4 2SO4; Materials chemistry; Materialkemi;

   Sammanfattning : The role of sodium chloride (NaCl) particles and ammonium sulfate ((NH4)2SO4) particles on the initial atmospheric corrosion of copper and zinc was investigated under in situ and ex situ conditions using microgravimetry, FTIR spectroscopy, ion chromatography, scanning electron microscopy with x-ray microanalysis and the scanning Kelvin probe. For the first time, in situ infrared spectra were collected on a micron level during particle induced atmospheric corrosion using a recently developed experimental set-up for in situ FTIR microspectroscopy.
