The application of k(t) - factorization, supplemented with the CCFM small-x evolution equation, to heavy quark production is discussed. Differential cross sections of b (b) over bar production and also inelastic J/psi production as measured at HERA are compared to the hadron level CCFM Monte Carlo generator CASCADE, using the unintegrated gluon density obtained within the CCFM evolution approach f

Popular Abstract in Swedish Avhandlingen syftar till att bidra till förståelsen av hur det kan komma sig att kristendomen i början av det andra århundradet utvecklas till en icke-judisk religion. Att de judendom och kristendom idag uppfattas som två olika religioner är inte så märkligt. Dock, om man betänker att kristendomen ursprungligen var en del av det första århundradets judendom så är det egThis book attempts to answer the question of how it is possible that Christianity in the beginning of the second century C.E. had developed into a non-Jewish, Gentile religion. Since Christianity was originally one of many Jewish factions within the diversified Judaism of the period, and one that even primarily seems to have directed its attention to the people of Israel, the problem of its separa

Tumor cells often carry mutations in genes that control cell survival, and become resistant to signals that trigger cell death. Yet, some cell death pathways remain intact in tumor cells. If identified, these pathways might be exploited to selectively remove tumor cells. HAMLET (human α-lactalbumin made lethal to tumor cells) is a protein-lipid complex derived from human milk that activates cell d

Translocation of peptides through cellular membranes is a fundamental problem in developing antimicrobial peptides and in drug delivery. There is a class of peptides, known as cell-penetrating peptides, that are able to penetrate membranes without disrupting them. They can carry pharmacological compounds, thus a promising strategy for drug delivery. The physical mechanisms that facilitate transloc

The molecular self-diffusion in concentrated aqueous mixtures based on an oppositely charged po ymer-surfactant pair has been investigated by NMR pulsed field gradient techniques. The investigated structures were an ordered cubic Pm3n phase (ca. 50 wt % water) and a disordered micellar phase, both containing cetyltrimethylammonium (CTA(+)) micelles with mixed acetate (Ac-) and polyacrylate (PA(-))

The influence of rate controlled flow reversal on the transition from planar lamellae to multilamellar vesicles (MLV) using a nonionic lamellar phase consisting of 40 wt % triethylene glycol monodecyl ether (C10E3 in D2O) is investigated by means of time-resolved rheo-small-angle light and neutron scattering (SALS, SANS). Flow reversal provides the possibility to control the kinetics of the transi

S100A8 and S100A9 are Ca(2+)-binding proteins that are associated with acute and chronic inflammation and cancer. They form predominantly heterodimers even if there are data supporting homodimer formation. We investigated the stability of the heterodimer in myeloid and S100A8/S100A9 over-expressing COS cells. In both cases, S100A8 and S100A9 proteins were not completely degraded even 48 hrs after

Arginine-rich cell penetrating peptides (ARCPPs) are known to quickly permeate cell membranes through a non-endocytotic pathway. Potential clinical applications of this facility have prompted enormous effort, both experimental and theoretical, to better understand how ARCPPs manage to overcome the prodigious thermodynamic cost of lipid bilayer permeation by these highly charged peptides. In this w

Purpose – The rate of turnover of hospital managers has been high in Sweden. Hospitals are regarded to be difficult to manage, which is connected with different discourses and action logics such as politics, medicine, care and management creating complex conditions for hospital management. The purpose of this paper is to analyse hospital managers' management conditions in conjunction with hospital

The present article reports on static and dynamic light scattering (SLS and DLS) studies of aqueous solutions of the nonionic surfactant C12EO6 and the poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) triblock copolymer EO20PO68EO20 (P123) at temperatures between 25 and 45 degrees C. In water, P123 self-assembles into spherical micelles with a hydrodynamic radius of 10 nm, and at 40
