After 50 years of its prediction, the highest-lying [2 0 2]3/2 orbit among the six Nilsson single-particle orbits originating from the sd shells in prolately deformed nuclei and the rotational band on this orbit were identified. The band members were observed in Al-25 at excitation energies of 6-7.5 MeV in a high-resolution Mg-25(He-3,t) charge-exchange reaction at 0degrees having a strong selecti
Insertion of metals into various tetrapyrroles is catalysed by a group of enzymes called chelatases, e.g. nickel, cobalt, magnesium and ferrochelatase. It has been proposed that catalytic metallation includes distorting the porphyrin substrate by the enzyme towards a transition state-like geometry in which at least one of the pyrrole rings will be available for metal chelation. Here, we present a
An experiment has been performed to search for superdeformed (SD) states in Dy-149,Dy-150. While no evidence for discrete superdeformed states has been observed, a superdeformed ridge with a separation of Delta E-gamma=52 keV with a total intensity of 1.8+/-0.5% that of Dy-150 has been observed. An upper limit of 0.8% (0.9%), of the intensity of Dy-150 (Dy-149), is placed for observation of the mo
Triglycerides and phospholipids 0.5-2mg (wet weight) of human liver material obtained by the fine-needle aspiration biopsy technique can be estimated after chloroform:methanol extraction by the determination of lipid phosphorus and glyceride glycerol. The methods are based on the colorimetric determination of inorganic phosphate after oxidation of the phospholipids and the enzymatic fluorometric d
n this study, Jordanian feldspar from Wadi Al-Jayshiah area was invested to evaluate its applicability as raw material for ceramic and industries. The chemical analysis indicated that the average Fe2O3 content is 2.33%, which is very high, compared to commercial ceramic and glass grades feldspar. The SiO2 content in the Wadi Al-Jayshiah feldspar (67.96%) lies within the required amount in commerci
The possibility of reducing the transient times at grade changes in paper production and machine start-ups on the paper machines has highlighted the need for increased knowledge of the steam supply system. Models in this area have been presented in previous work and it is of interest to compare these models with each other and evaluate them against experimental data. This paper reports on the resu
Popular Abstract in Swedish Människan har märkbart ändrat Jordens ekosystem och dess funktioner. Genom avskogning och konvertering av naturliga ekosystem till åkrar och betesmarker så har människor skapat helt nya typer av ekosystem. Cirka en tredjedel av den koldioxid (CO2) som människor har släppt ut i atmosfären, kommer från dessa aktiviteter, resten beror till största delen på utsläpp från förThrough deforestation and conversion of natural ecosystems to croplands and pastures, have humans released vast amounts of carbon (C) dioxide (CO2) into the atmosphere. Roughly one third of the cumulative anthropogenic emissions until today stem from these practices, the remainder being mostly due to fossil fuel combustion. The extra CO2 has caused an increase in global air temperature, and both t
Popular Abstract in Swedish Om flyttningens betydelse för utbredningsmönster för arktiska fåglar Sara Henningsson Fågelflyttning är en anmärkningsvärt framgångsrik strategi som möjliggör att en större mängd individer kan försörjas genom rörelser mellan olika regioner. Inom dessa olika områden, som ofta ligger mycket långt ifrån varandra, kan fåglarna utnyttja stora säsongsmässigt tillgängliga resFlexibility as well as constraints to the evolution of migration routes has the possibility of affecting large-scale patterns of geographical ranges of animals both by facilitating, but sometimes restricting, accessibility to and colonization of new regions. This dissertation concerns the broad-scale effects migration has on the distributional patterns of birds in the Arctic. I studied the circu
Growing and eating food are cultural practices that simultaneously make physical bodies, shape landscapes, and produce racial (together with class/ethno/spatial) knowledge and identity. This chapter strives to complement the large body of work on race and racism in Brazil and elsewhere with an exploration of how some people in the Brazilian state of Bahia experience and communicate racialized iden
The paper describes a novel extraction procedure for lipopolysaccharides (LPS) from Salmonella enterica subsp. enterica (PCM 2266). Process parameters for the extraction of LPS from bacterial mass were optimized by carrying out a two-level fractional design experiment. Four parameters, namely temperature, CO, flow rate, pressure and co-solvent composition were analyzed. The best crude extract yiel
With the aim of properly understanding the basis for and the utility of many-body perturbation theory as applied to extended metallic systems, we have calculated the electronic self-energy of the homogeneous electron gas within the GW approximation. The calculation has been carried out in a self-consistent way; i.e., the one-electron Green function obtained from Dyson’s equation is the same as tha
Popular Abstract in Swedish Genetisk påverkan i ledgångsreumatism Ett väl fungerande immunsystem är en förutsättning för kroppens kamp mot diverse sjukdomar orsakade av t ex virus och bakterier. En grundläggande egenskap hos immunsystemet är dess förmåga att skilja på vad som är kroppens egna celler och molekyler och vad som är främmande. Ibland fungerar inte denna diskriminering som den ska och In this thesis the role of major histocompatibility complex (Mhc) class II molecules in development of autoimmune disease such as rheumatoid arthritis (RA), was studied. By combining an experimental model for RA, collagen type II induced arthritis (CIA), with molecular biology methods the importance of polymorphism in Mhc class II genes for disease development was investigated. The Mhc region con
