In the collinear factorization scheme the minijet cross section diverges for small k [perpendicular]. In the k[perpendicular]-factorization formalism this divergence is avoided, and it is possible to calculate the number of minijets and the E[perpendicular]-flow exclusively from HERA data, without reliance on a phenomenological soft cutoff. The hadron multiplicity is very sensitive to non-perturba
This thesis consists of four self-contained essays on different conflicts shaping local government policy. The first essay examines how population aging affects the generosity of public long-term care. Aging may directly affect long-term care policy as the elderly become a more important voter group. However, concerns for other citizens may dampen the political importance of the elderly. Fixed e

Popular Abstract in Swedish Brosk är en typ av vävnad som finns på många olika ställen i vår kropp. Karakteristiskt för brosk är att det är mycket hållfast samtidigt som det medger en hög grad av flexibilitet. Ledbrosket är det tunna brosklager som klär kortändarna på benen i skelettet. Dess uppgift i leden är att fungera som stötdämpare för att skydda det underliggande benet samt att utgöra den gIntegrins are a family of cell surface receptors known to bind matrix proteins and to mediate signals such as mechanical signals between the cell and the surrounding matrix. We have studied integrins that are expressed by chondrocytes, with specific focus on the integrins that interact with the cartilage matrix protein collagen type II. It was found that chondrocytes isolated from articular cartil
The enzyme ferrochelatase (EC 4.99.1.1) is the terminal enzyme in the biosynthetic pathway of heme b and catalyzes the insertion of Fe(II) into protoporphyrin IX. In this dissertation ferrochelatase from Bacillus subtilis was studied. A new purification method via inclusion bodies was developed that enabled simple purification of recombinant enzyme without tags or modifications that might affect t
