Background. The incidence and severity of invasive group A streptococcal infection demonstrate great variability over time, which at least, in part, seems to be related to group A streptococcal type distribution among the human population. Methods. An enhanced surveillance study of invasive group A streptococcal infection (746 isolates) was performed in Sweden from April 2002 through December 2004
Exact diagonalization calculations reveal that the energy spacing Delta in the conduction band tunes the interplay between the local Kondo and nonlocal Ruderman-Kittel-Kasuya-Yosida (RKKY) interactions, giving rise to a Doniach phase diagram for a nanocluster with regions of prevailing Kondo or RKKY correlations. The parity of the total number of electrons alters the competition between the Kondo

I sex fallstudier vid fyra medelstora verkstadsföretag inom mekanisk industri utvecklades en metodik för att analysera och beskriva existerande och planerad arbetsmiljö och produktion med hjälp av datorgenererade bilder. Användningen av bilder skedde inom ramen för en aktionsforskningsmetodik, där chefer och berörda anställda tillsammans med fack och representanter för företagshälsovården samverka
Chemical beam epitaxy has been used to grow III/V nanowires seeded from size selected Au aerosol particles. Both chemically uniform InAs wires as well as InAs wires containing one or several heterostructure interfaces were grown. The interfaces were characterized in a transmission electron microscope revealing atomically sharp interfaces and also that, barriers as thin as only 2-3 monolayers and u
Popular Abstract in Swedish En av de viktigaste substanserna i vår kropp är proteiner, också kallade äggviteämnen. Proteiner har en mängd olika uppgifter i kroppen, de finns i våra celler där de har olika uppgifter såsom att fungera som enzymer, transportörer, signalsubstanser, eller som skyddsfaktorer. Proteiner ingår också som viktiga beståndsdelar i vävnaderna mellan cellerna och finns dessutomPathogenic bacteria express a wide array of surface proteins that interact with the environment. Many of these proteins are believed to be important for the virulence. This thesis deals with the binding of immunoglobulins (Ig) and complement regulating proteins to certain bacterial surface proteins. Protein L from Peptostreptococcus magnus binds to Igk-light chains while protein A from Staphylococ
My focus is on pragmatic arguments for various ‘rationality constraints’ on a decision maker’s state of mind: on his beliefs or preferences. An argument of this kind purports to show that a violator of a given constraint can be exposed to a decision problem in which he will act to his guaranteed disadvantage. Dramatically put, he can be exploited by a clever bookie who doesn’t know more than the a
