Mångfalden i användningen av modeller i betydelsen analogier i vetenskapligt språk beskrivs: visualiseringar, typexempel, och (vanligast) begreppsliga och teoretiska konstruktioner. En annan användning är när vetenskapliga teorier som sådana uppfattas som modeller. De betraktas då som något annat än bokstavliga beskrivningar av verkligheten, som i exv. i instrumentalismen och den kritiska realisme
Under vårt rundabordssamtal på inspirationskonferensen 2012 vill vi utbyta erfarenheter kring att utveckla och sprida e-lärande och digitala resurser vid ett lärosäte. Vår utgångspunkt är det universitetsgemensamma projektet Webbaserat lärande och digitala resurser. En mötesplats för dialog, erfarenhetsutbyte och förädling av goda idéer kring studenters lärandemiljöer (Irhammar & Landgren 2011
Popular Abstract in Swedish Helicobacter pylori är en Gramnegativ spiralformad human-specifik patogen med förmåga att penetrera magsäckens slemlager och kolonisera i epitelskiktet. H. pylori infektion betraktas som en högriskfaktor för utvecklandet av kronisk gastrit, magsår och ventrikelcancer. H. pylori har en komplex cellyta med ett flertal kolhydratbindande proteiner, sk. lektiner att interageHelicobacter pylori is a gastric pathogen colonising the gastric mucus layer and epithelium of gastric tissue and is associated with chronic type B gastritis and peptic ulcer disease. The attachment of H. pylori to gastric epithelial cells involves several structures recognised by specific bacterial surface proteins. Since colonisation is an initial and critical step in the development of a chroni
This thesis describes the design and characterisation of a vacuum ultraviolet scanning photoelectron microscope as well as results from studies of laterally inhomogeneous surfaces. The instrument utilises synchrotron radiation from an undulator at the 550 MeV storage ring at the MAX-laboratory. The beamline is comprised of a plane-grating monochromator with a Kirkpatrick-Baez objective and a graz
Closed loop lab tests of a dual-conjugate adpative optics setup are presented. The corrected field of view is improved compared to ground-layer and single-conjugate adaptive optics. The setup is eventually intended for on-sky observations.
Fredrik Wulff, professor in French and Spanish, expert in prosody and fonetics, listened to Birger Sjöberg' s performance in Lund 1923, and made notes of Sjöberg's performance and language, i. e. Sjöberg's choice of words and dialect. Wulff's letter or notes are extremely interesting as it is the only testimony one has of Sjöberg' s dialect and habit of performance.
Centralized Petersen coil earthing in networks with extensive use of underground cable involves flow of large quantities of reactive earth fault current. In networks with long radial cable feeders this creates problems involving active losses and active and reactive earth fault current. One possible solution to the problem is the use of local compensation. This paper aims at understanding the limi
Many politicians and researchers perceive wind power as an important part of future energy supply, nationally and globally. However, it has turned out to be problematic to expand wind power in the pace necessary to meet the national and international goals about wind power expansion. A significant challenge concerns the social and policy-related processes surrounding the establishment of wind powe
