1. 11. Factors influencing emission fluxes and bacterial enrichment in sea spray aerosols : Insights from laboratory and field studies

   Författare :Julika Zinke; Matthew E. Salter; Paul Zieger; Rachel A. Foster; E. Douglas Nilsson; Patricia K. Quinn; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sea spray aerosols; eddy covariance fluxes; air-sea-exchange; bacteria; primary biological airborne particles; laboratory studies; field studies; Baltic Sea; North-Eastern Atlantic; Environmental Sciences; miljövetenskap;

   Sammanfattning : Sea spray aerosol (SSA) is one of the major natural aerosol sources and is produced when wave breaking entrains air into ocean surface water, which subsequently breaks up into bubbles. These bubbles rise to the surface and can scavenge biogenic material. LÄS MER

3. 12. Tools for the Advancement of Radiopharmaceutical Therapy

   Författare :Emma Mellhammar; Forskningsgruppen för Systemisk strålterapi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiopharmaceutical therapy; Nuclear medicine; Monte Carlo simulation; Intratherapeutic preclinical PET; Alpha particles; Beta Particles; radionuclides; Radiobiology; γ-H2AX; Dosimetry;

   Sammanfattning : Radiopharmaceutical therapy is used to treat cancers and other diseases with radiolabeled pharmaceuticals. The treatment targets specific cells, and the emitted ionizing radiation cause cytotoxic damage. Dosimetry is performed to estimate the absorbed dose from the energy deposited in the body. LÄS MER

4. 13. Nano-particulate Silica Hydrogels Imaged in 2D and 3D using TEM: Effects of local pore structure on mass transport and applications in aggregation dynamics

   Författare :Charlotte Hamngren Blomqvist; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; silica gel; colloidal silica gel; interconnectivity; nanoporous; electron tomography; silica nanoparticle gel; mass transport; nanostructure; accessible volume fraction; 3D structure;

   Sammanfattning : Porous materials are frequently used in everyday applications including food science, pharmaceuticals, fuel cell membranes, batteries and solar cells. A key aspect in these porous materials is how their micro- and nano-structure affect the internal transport of for example water, particles or charges. The transport is a three-dimensional process.

5. 14. Computational modeling of biological barriers

   Författare :Christian Wennberg; Erik Lindahl; Thomas Cheatham; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular dynamics; cholesterol; lipid bilayer; permeability; long-range interactions; Lennard-Jones; dispersion; particle-mesh Ewald; stratum corneum; skin formation; Biological Physics; Biologisk fysik;

   Sammanfattning : One of the most important aspects for all life on this planet is the act to keep their biological processes in a state where they do not reach equilibrium. One part in the upholding of this imbalanced state is the barrier between the cells and their surroundings, created by the cell membrane. LÄS MER

7. 15. Exploring the Interactive Landscape of Lipid Bilayers

   Författare :Christian L. Wennberg; Erik Lindahl; Arnold Maliniak; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular Dynamics; lipid bilayer; cholesterol; permeability; long-range interactions; Lennard-Jones; dispersion; particle-mesh Ewald; Biological Physics; Biologisk fysik;
