Periodic minimal surface structures in bicontinuous lipid-water phases and nanoparticles

The accumulated evidence for the existence of periodic minimal surface (PMS) bilayer structure of the bicontinuous cubic phases in lipidwater systems is summarized. There are three fundamental PMS: the G, D, and P types. These three and no others have been observed in lipid-water systems. Due to the so-called Bonnet relation, the PMS structures are isometric conjugates to one another at coexistenc

Living with cancer in old age. Quality of life and meaning.

Popular Abstract in Swedish ”Att leva med cancer som äldre, livskvalitet och upplevelse av mening” Cancer drabbar företrädesvis äldre personer och är en sjukdom som blir vanligare i takt med det stigande antalet äldre i befolkningen. Cancer hos äldre innebär en komplex situation eftersom åldrandet är präglat av stora individuella förändringar med ökande sjuklighet, nedsatt funktionell förmåga, föThe overall aim of this thesis was to investigate quality of life in people aged 75 and older with cancer in relation to age, gender, presence and type of complaints, comorbidity, living conditions, perceived economic situation, sense of coherence, receiving help for daily living and social resources. The aim was also to investigate older people’s experiences and the meaning of living with cancer

Beta-galactosidase from a cold-adapted bacterium: purification, characterization and application for lactose hydrolysis.

The enzyme beta-galactosidase was purified from a cold-adapted organism isolated from Antarctica. The organism was identified as a psychrotrophic Pseudoalteromonas sp. The enzyme was purified with high yields by a rapid purification scheme involving extraction in an aqueous two-phase system followed by hydrophobic interaction chromatography and ultrafiltration. The beta-galactosidase was optimally

Bi-isonicotinic acid on TiO2 rutile (110): calculated molecular and electronic structure

Bi-isonicotinic acid adsorption on rutile TiO2(1 1 0) surfaces has been studied using periodic first principles density functional calculations. The geometry of a dissociatively bridge-bonded adsorbate has been optimized, and the influence of the position of the dissociated protons on the surface examined. The results are in agreement with published experimental information on the adsorption geome

Severe extra-articular disease manifestations are associated with an increased risk of first ever cardiovascular events in patients with rheumatoid arthritis

Background: Rheumatoid arthritis is associated with increased cardiovascular mortality and morbidity. Objective: To assess the effect of severe extra-articular rheumatoid arthritis (ExRA) manifestations on the risk of cardiovascular disease (CVD) in patients with rheumatoid arthritis. Methods: Patients with ExRA (n = 81) according to predefined criteria and controls (n = 184) without evidence of e

Islamisk predikan på ljudkassett : en studie i retorik och fonogramologi

Popular Abstract in Swedish Avhandlingen handlar om islamisk predikokonst i teori och praktik, med särskilt fokus på islamisk predikan inspelad och publicerad på ljudkassett. Huvudmaterialet består av fyra kassetter med inspelningar av predikningar på arabiska: 1) Ismail Hamidi, ”Underrättelsen om uppståndelsens dag”; 2) Ahmad al-Qattan, ”Vägen till Paradiset/Lustgården”; 3) Ahmad al-Qattan, ”BeräThe dissertation deals with Islamic preaching in theory and practice, with special focus on material recorded and published in the format of audiotapes/cassettes. One aim is to explore possible implications of the use of this special format of publication in the context of Islamic preaching. How is this new format of publication to be understood in relation to the norms regulating the activity of

Experimental verification of tomographic measurement methods in ultrasound

This thesis describes two different measurement methods applied to ultrasound. The first method, Ultrasound doppler vector tomography, uses ultrasound to measure blood flow and the second method, Light diffraction tomography, measures the pressure field in an ultrasound beam with laser light. Both methods depend on tomography algorithms for reconstruction of the measured region. A prime motive fo

ECONOMIC AND SOCIAL CRISES IN SIERRA LEONE : The Role of Small-scale Entrepreneurs in Petty Trading as a Strategy for Survival 1960-1996

Popular Abstract in Swedish Målsättningen med avhandlingen är att analysera vilken roll småskaligt entreprenörskap som alternativ överlevnadsstrategi har spelat i Sierra Leone under den ekonomiska kris som drabbade landet efter självständighet på 1960-talet. Avhandlingen baseras på nätverksteori, snowball metod och det empiriska underlaget utgörs av en studie av utvecklingen i Sierra Leone, med avSierra Leone is a small country with rich mineral resources such as diamonds, bauxite, gold and iron ore. Other resources include fishing, forestry and fertile agricultural land, which enable people to farm without any sophisticated methods of mechanization. Nevertheless, with all its wealth in resources, the country is relatively poor and is one of the least developed countries in the Sub-Saharan

Measurement of dijet cross sections in ep interactions with a leading neutron at HERA

Measurements are reported of the production of dijet events with a leading neutron in ep interactions at HERA. Differential cross sections for photoproduction and deep inelastic scattering are presented as a function of several kinematic variables. Leading order QCD simulation programs are compared with the measurements. Models in which the real or virtual photon interacts with a parton of an exch

Genes in the HLA class I region may contribute to the HLA class II-associated genetic susceptibility to multiple sclerosis

In order to analyze whether loci in the human leukocyte antigen (HLA) class I region may contribute to the HLA class II-associated genetic susceptibility to multiple sclerosis (MS), we examined selected microsatellite markers in 177 Nordic sib-pair families, 222 British sib-pair families, 323 sporadic Norwegian MS patients and 386 Norwegian controls. All samples were, in addition, genotyped for th

Design of concentrating elements with CIS thin-film solar cells for facade integration

A concentrating photovoltaic wall element, including Cu(In, Ga)Se-2-based modules, aluminum reflectors, and an insulation for building integration, has been developed and evaluated. The geometric concentration ratio of the system is about 3 x. However, the measured maximum electric power from the modules is only 1.9 times that of identical vertical modules without reflectors, due to optical losses

Rotational structures and their evolution with spin in Gd-152

The fusion-evaporation reaction involving a 175 MeV S-36 beam and a Sn-124 target was performed, and the emitted gamma rays were observed with the Gammasphere spectrometer. Significant additions to the level scheme of Gd-152 were made in spite of the relative weakness of the alpha 4n exit channel, being only similar to 2% of the total fusion cross-section. The high-spin behavior of Gd-152 was comp

Self-Knowledge/Self-Regulation/Self-Control: A Ubiquitous Computing Perspective

This thesis is about self-knowledge, self-regulation and self-control. All three of these terms are easily understandable, and apply to situations in our daily lives (like misjudging one’s own competence at retiling the bathroom floor, or feeling the anxiety and thrill of doing unsupervised work, or guiltily hitting the snooze-button for the fifth time, and missing half a day of school). The five
