Popular Abstract in Swedish Vårt immunsystem är uppbyggt runt två typer av celler som har som uppgift att försvaraoss mot infektioner. T lymfocyterna står för det cellmedierade immunförsvaret som är speciellt viktigt för att bekämpa virusinfektioner med B lymfocyterna har som uppgift att producera antikroppar. Antikroppar finns i alla kroppsvätskor och kan interagera med toxiner, virus och bakteriEach immunoglobulin (Ig) V gene segment contains an upstream promoter region. The octamer element and the TATA box are the only elements that are conserved in all Ig promoters. The presence of the octamer element is necessary, but not sufficient to support high levels of transcription. Therefore, the activity of other co-stimulatory elements is required. This investigation has focused on the study

Over the past few decades new cities have appeared around the world in undeveloped areas. And although development has expanded significantly and become bolder and more innovative, the above-average scale at which the countries of the Persian Gulf are growing stands one level above the rest. The United Arab Emirates obtained independence in 1971 with a GDP of 6.5 billion Dirhams (US$ 1.6 billion);

Existing econometric approaches for studying price discovery presume that the number of markets are small, and their properties become suspect when this restriction is not met. They also require making identifying restrictions and are in many cases not suitable for statistical inference. The current paper takes these shortcomings as a starting point to develop a factor analytical approach that mak

Radiative lifetimes have been studied in neutral copper, gold, magnesium, zinc, tellurium, sulphur, selenium, bismuth and helium and in singly ionised platinum and palladium. The radiative lifetimes were determined by time-resolved spectroscopy following single, two-photon or stepwise laser excitation. The excitations required short wavelengths, obtained by frequency mixing of radiation from pulse

The study reports on the practices of illegal file sharing in Sweden during the period 2007-2012. More than 1.000 posts in response to the question “You guys who download stuff illegally, don’t you ever feel guilty?” where analyzed with regard to the respondents’ expressed senses of guilt, whether file sharing was right or wrong, if they buy media, together with dimensions of stakeholders and medi

Popular Abstract in Swedish Kring millenieskiftet 2000 skulle den nya ekonomins företag framför allt vara snabba. Men vad är då egentligen ett snabbt företag, och hur blir ett företag snabbt? Internetkonsultföretaget Framfab (Framtidsfabriken) kom under ett par år att representera just de snabba företagen i Sverige. Med sin VD Jonas Birgersson i spetsen och med hjälp av ny digital teknik skulle föFor some years the new economy in Sweden was to a high extent represented by a couple of new and fast growing companies. One of these was the Internet consultancy Framfab (Framtidsfabriken). The company became synonymous with the unusual and exciting, a new kind of business, new products and new attitudes. In national media Framfab was mostly represented by its C.E.O. Jonas Birgersson, who in ofte

Gaia is ESA’s ambitious space astrometry mission with a foreseen launch date in early 2012. Its main objective is to perform a stellar census of the 1000 Million brightest objects in our galaxy (completeness to V=20 mag) from which an astrometric catalog of micro-arcsec level accuracy will be constructed. A key element in this endeavor is the Astrometric Global Iterative Solution (AGIS) - the math

Vännerna från skoltiden har för många en stor betydelse. När den kände palestinsk-amerikanske litteraturvetaren Edward W. Said skrev sitt livs historia insåg han att just vännerna från sina tidiga skolår påverkat hans liv mer än vad andra vänner gjort. I "Utan Hemvist" berättar han också om sin mamma. När mamman talade om en person som hon uppskattade och spenderade mycket tid tillsammans med på ä
