Interactions between mycorrhizas and soil microbial and faunal populations, including those between different mycorrhizal populations are discussed along with the nutritional and non-nutritional interactions between fungi and plant roots and their influence on the structure, development and functioning of plant communities. The discussions relate principally to vesicular-arbuscular and ecto-mycorr
We mapped the genetic influences for type 1 diabetes (T1D), using 2,360 single-nucleotide polymorphism (SNP) markers in the 4.4-Mb human major histocompatibility complex (MHC) locus and the adjacent 493 kb centromeric to the MHC, initially in a survey of 363 Swedish T1D cases and controls. We confirmed prior studies showing association with T1D in the MHC, most significantly near HLA-DR/DQ. In the
The application of feedback control to computing systems is a promising research area, but has to date been hindered by the almost unanimously perceived complexity in creating control-oriented system models. Computing systems are in fact considered very hard to describe with dynamic models allowing for simple and powerful control design tools, so that complex ones need bringing in to the detriment

Varje dag överlåts företag och företagsgrupper omstruktureras. Ofta rör det sig om stora värden och det är inte ovanligt att en företagsöverlåtelse påverkar de inblandade parterna under lång tid. Skatt är ofta den väsentligaste transaktionskostnaden. Av den anledningen är det mycket viktigt att kunna förutse de skattekonsekvenser som uppkommer i och med överlåtelsen. Beskattning av aktiebolag vi
In order to prepare for the potentially negative influence of insertion devices (IDs) on beam lifetime, injection effi- ciency and beam size in the MAX IV 3 GeV storage ring, a strategy for neutralizing the foreseen effects of the IDs has been developed. The strategy involves a local correction of the betatron phase advance by adjusting the strength of the quadrupoles adjacent to the ID as well as
Popular Abstract in Swedish Staren i jordbrukslandskapet Under de senaste tre decennierna har staren (Sturnu's vulgari's) i likhet med många andra fågelarter knutna till jordbrukslandskapet minskat kraftigt i antal, både i Sverige och i stora delar av västra och norra Europa. Det finn's flera tänkbara förklaringar till detta, men eftersom jordbruket under samma tidsperiod genomgått stora förändriThe European Starling Sturnus vulgaris as many other farmland bird species has been declining during the last decades. The cause of these declines is generally believed to be changes with in agricultural methods affecting breeding and survival of birds. For starlings in Southern Sweden the amount of pasture in the landscape surrounding breeding colonies is the key factor. We found a positive relat
Popular Abstract in Swedish Idag kan vi mäta mycket låga halter av gifter i t. ex. dricksvatten och livsmedel, bland annat genom utvecklingen av nanosensorer. Sensorerna kan också använda's medicinskt, t. ex för att väsentligt underlätta livet för diabetiker. Idag drabba's diabetespatienter ofta av nedsatt känsel i fingrarna på grund av dagliga nålstick. Med hjälp av de nya sensorerna kan vi nu mäA new type of Bioelectronic Nanosensor Device with potential applications in medicine,biotechnology and environmental analysis was designed. The nanosensor is based on RISFET (Regional Ion Sensitive Field Effect Transistor) technology. The design of the nanosensor involves use of a set of nano-sized electrodes on the surface of a silicon chip, giving the chip the ability to sense extremely low con
