Popular Abstract in Swedish Vid Compton spridning sprids fotonen elastiskt, dvs. utan att förlora energi, mot en annan partikel eller kärna. Kärnorna som användes i detta försök består av en proton och en neutron (sk. deuterium, eller tungt väte). Kärnorna bestrålades med fotoner av kända energier och de spridda fotonerna detekterades mha. stora NaI-detektorer som var placerade i olika vinklar runA series of three Compton scattering experiments on deuterium have been performed at the high-resolution tagged-photon facility MAX-lab located in Lund, Sweden. The 50 < Eg < 70 MeV tagged photons were scattered from a liquid deuterium target and detected simultaneously in three (10"x10") NaI detectors. The average laboratory angles investigated were 45, 125 and 135 deg. The influence of the inela

Global climate change has enormous impacts on urban areas in the developing world. The known and growing effects of climate change, like increased temperatures and increased incidence of severe storms, is evident. This winter, 2015, extreme cold waves and snow storms hit the Middle East region. Death rates in Syrian refugee camps were significant due to inefficient temporary shelters. Children and

DT cell activation requires the combination of antigen in the context of MHC and costimulatory molecules to induce a functional immune response. For our studies, we primarily utilized superantigens (SAg) that bind MHC class II molecules as first signal. Mutations in the SAg MHC class II a-chain binding site reduced the number of responding T cells expressing particular TCR Vb chains, whereas mutati

Popular Abstract in Swedish Ämnen som har stor löslighet i vatten kallas i regel för "hydrofila", vilket betyder "vattenälskare". Exempel på sådana ämnen är socker, koksalt, ättika och etanol. Dessa ämnen består av små molekyler. Det finns emellertid även ämnen som består av stora molekyler och som också har stor löslighet i vatten, t. ex. gelatin, stärkelse och agar. En annan grupp av ämnen har lThe partitioning behaviour of different types of molecules in thermoseparating two-phase systems has been studied. A thermoseparating two phase system was formed by heating a water solution, which contained a thermoseparating polymer, above the cloud point temperature. The thermoseparating polymers studied were: random copolymers of ethylene oxide and propylene oxide (EOPO-polymers), and ethyl(hyd

Popular Abstract in Swedish I cellen styrs allt av biomolekylernas förmåga till igenkänning och växelverkan med varandra. Molekylernas speciella egenskaper bygger upp kroppens alla komplicerade funktioner, till exempel immunförsvar, celldelning och muskelarbete. Interaktionerna mellan biomolekylerna kan vara av olika karaktär; de beskrivs som starka eller svaga (affinitet), långsamma eller snabba Molecular recognition and interaction is fundamental for the function of biological systems. The properties of the interacting biomolecules dictate the type of forces involved and the strength and dynamics of the interaction. Many interactions are very strong whereas others exhibit weak affinity. Typically, weak interactions work in concert to trigger a biological response. The advantage with thi

This paper scrutinizes the Swedish concept of "äventyr" (adventure), originally the key concept of mediaeval chivalric romance, that has become one of the most popular concepts used in contemporary mass media. Influenced by the European development, "äventyr" has been applied in various contexts. A diachronic survey of Swedish sources from 1300 to 2004 enables us to reconstruct changing conceptual

Popular Abstract in Swedish Denne afhandling vedrører geriatriske patienters ernæringsproblemer indenfor rammen af geriatrisk rehabilitering. Geriatriske patienter er svækkede ældre mennesker, der er præget af aldring og kronisk sygdom. Den hændelse som er årsag til indlæggelse er ofte som toppen af et isbjerg, hvor der kan ligge mange andre problemer gemt under vandoverfladen. En lungebetændelse The aim was to evaluate the effectiveness and feasibility of functional and nutritional assessments in geriatric rehabilitation in Copenhagen, Denmark, and in addition to study clinically identifiable risk factors for undernutrition, association between nutritional and ADL status, feasibility and effectiveness of nutritional intervention conducted by the nursing staff, and the nursing staffs attit
