It is often suggested that the emittance coupling of a storage ring should be adjusted to the so-called diffraction limit corresponding to the shortest wavelength of interest. For 1 Å radiation this leads to a typical requirement of 8 pm rad vertical emittance. In ultralow-emittance storage rings like the MAX IV 3 GeV storage ring this corresponds to a comparably large setting of the emittance cou

Texten behandlar hur Strindberg använt sig av Rydbergs karaktär Hermione i Den siste athenaren när han skrev sitt drama "Hermione".

Popular Abstract in Swedish Denna avhandling handlar om stora nätverk av oscillatorer. En oscillator är ett system som beter sig periodiskt. Speciellt handlar avhandlingen om oscillatorer som har ett typiskt beteende. En egenskap som varje sådan oscillator har är den naturliga frekvens med vilken beteendet upprepas. Om vi stör oscillatorn, så återvänder den så småningom till sitt typiska beteende.This thesis deals with large networks of limit cycle oscillators. A limit cycle oscillator is a dynamical system that has a periodic attractor in phase space, and is defined in continuous time. To each such oscillator one can associate a natural frequency. Virtually all biological systems that show periodic oscillations can be seen as limit cycle oscillators. The same is true for oscillating mecha

The implementation of multiband diversity antennas in compact mobile handsets, for the purpose of increasing transmission quality, is a topic of current interest in the mobile phone industry. In order to achieve the expected performance improvement in typical operating conditions, we not only have to contend with the challenges of designing multiple multiband antennas, which are closely spaced wit

The durability of a road is among other factors dependent on the affinity between stones in the top layer and bitumen that holds the stones together. Poor adherence will cause stones to detach from the surface of the road more easily. The rolling bottle method is the standard way to determine the affinity between stones and bitumen. In this test a number of stones covered in bitumen are put in a r

Popular Abstract in Swedish Effekter av narkosgas, låg syrgashalt och blodförlust under blodspädning (hemodilution) på sövda grisar. Blodspädning (hemodilution) används under operation för att minska behovet av blodtransfusion med dess inneboende risker. Hemodilution innebär att blod tappas före operationsstart och ersätts med en blodkroppsfri lösning. Om en blödning uppstår under operationen blirHemodilution reduces the need for blood transfusion and hereby the risk for transmission of infectious agents. The present study investigated effects on systemic and myocardial circulation and oxygenation, and blood lactate concentrations; induced by nitrous oxide, isoflurane, hypoxia, and uncompensated blood loss, in pigs hemodiluted to a hematocrit of 11%. In addition, indicators of hypovolemia
