The M protein family of molecules in the group A streptococcus comprises a number of cell surface proteins that interact with the immune system of the host. One of the proteins in this family is the IgA receptor Arp4, which has C repeats similar to those that characterize the known M proteins. The streptococcal strain expressing Arp4 also expresses a second immunoglobulin-binding protein, Mrp4, wh
In the equation for thermal energy output from a flat-plate solar collector (written as a function of the collector mean heat carrier temperature), both the gain and the loss terms are multiplied by the collector efficiency factor, F'. For a concentrating collector with an uneven (non-uniform) irradiation on the absorber, the efficiency factor for the gain term, here called the optical efficiency
The M protein of Streptococcus pyogenes is a major bacterial virulence factor that confers resistance to phagocytosis. To analyze how M protein allows evasion of phagocytosis, we used the M22 protein, which has features typical of many M proteins and has two well-characterized regions binding human plasma proteins: the hypervariable NH2-terminal region binds C4b-binding protein (C4BP), which inhib
Ash is produced in combustion of biomass. Sonic part of this matter is called fly ash and is carried by the flow and causes not only air pollution and erosion, but also call affect the thermal radiation. The effects of fly ash particles oil the thermal radiation are considered ill this investigation. By analyzing sampled data in all electrostatic filter, a realistic particle size distribution is f
Popular Abstract in Swedish Hur gör bakterier för att komma undan immunförsvaret? Vi har studerat hur en vanligt förekommande bakterie, grupp A streptokocker, gör för att undvika kroppens immunförsvar vid infektion. Vi har upptäckt enzymer som bidrar till bakteriens förmåga att undvika immunförsvaret genom att avväpna antikroppar. De bakteriella enzymerna kan användas i bioteknisk industri och eveA majority of the proteins of the immune system are glycosylated and the glycans of IgG are essential for its functionality. Bacteria display enzymes that modulate the glycans of the immune system to weaken the host defense and favor bacterial survival. In this thesis we aimed at exploring bacterial modulation of host glycosylation in infection and to evaluate the usefulness of bacterial enzymes i
Förevarande uppsats genomför en komparativ analys av den svenska och danska krigslagstiftningen. I Sverige utgörs regelverket av 15 kap. regerings- formen med syfte att bibehålla legalitet oavsett vilka påfrestningar landet ställs inför. Kapitlet behandlar till stor del besluts- och normgivningsfrågor och olika nödförfaranden för när något statsorgan inte kan verka som vanligt. Vidare har Sverige
Wall-bounded turbulence is relevant for many engineering and natural science applications, yet there are still aspects of its underlying physics that are not fully understood, particularly at high Reynolds numbers. In this study, we investigate fully developed turbulent pipe flows at moderate-to-high friction velocity Reynolds numbers ( 361 ≤ R e τ ≤ 2000 ), corresponding to bulk velocity-based Re
There is no alternative! Margaret Thatcher once proclaimed in order to defend neoliberalist reforms and – implicitly – the capitalist regime. But if one doesn’t agree with Thatcher’s definition of the situation and her (and her many followers’) subsequent analysis, what viable options does one really have? Is it possible to come up with an empirically grounded alternative to the dominant modes of
The European Solar Telescope (EST) is a project aimed at studying the magnetic connectivity of the solar atmosphere, from the deep photosphere to the upper chromosphere. Its design combines the knowledge and expertise gathered by the European solar physics community during the construction and operation of state-of-the-art solar telescopes operating in visible and near-infrared wavelengths: the Sw
