In this work it is shown that domains of ordered dipoles are formed in large droplets made from dipolar particles provided that the dipole-dipole interaction between nearest neighbors is larger than the thermal energy. The size of the domains grows almost linearly with the size of the droplets for droplets containing 1000-30 000 particles. The largest domains occupy around 25-35% of the droplet vo

The use of (U-Th)/He thermochronometry in old slowly cooled terranes has long been debated. Hence, studies of natural setting are needed to verify the expected diffusivity behaviour of helium. Our results demonstrate that the (U-Th)/He method can be applicable to samples older than 200 Ma, and that available helium diffusion models can reproduce the results obtained from the age-vs.-depth trends.

Eight cold-adapted, polygalacturonase-producing yeasts belonging to four species were isolated from frozen environmental samples in Iceland. They were identified as Cystofilobasidium lari-marini, Cystofilobasidium capitatum, Cryptococcus macerans and Cryptococcus aquaticus species by sequence analysis of rDNA regions. Growth behavior of the isolates was investigated. All strains could grow at 2°C.

Purpose: Tardigrades have a reputation of being extremely tolerant to extreme environmental conditions including tolerance to ionizing radiation while in a desiccated, anhydrobiotic state. However, the evidence for radio-tolerance in tardigrades is based on only one previous report, and there is an obvious need for complementary studies. In this paper we report an investigation on radio-tolerance

BACKGROUND: Hypothermia may be accidental or therapeutic. Therapeutic hypothermia is increasingly used as treatment for various conditions, e.g., neuroprotection after cardiac arrest. Hypothermia leads to an impairment of the coagulation system, but the degree of impairment has been difficult to determine. Most studies have been performed on plasma instead of whole blood. We therefore evaluated wh

Syftet med denna avhandling har varit att undersöka tvångsvårdens legitimitet. För det ändamålet har jag genomfört, spelat in och transkriberat kvalitativa intervjuer med 80 klienter – som var föremål för LVM-vård våren 2006 – samt deras socialsekreterare när klienterna dels var intagna på LVM-hem och dels vid en uppföljning cirka sex månader efter tvångsvårdens slut. Avhandlingen utgår från fem The aim of this dissertation was to examine the legitimacy and the legitimizing of compulsory care for substance abusers according to LVM. For this purpose I have conducted, recorded and transcribed qualitative interviews with 80 clients – taken into such care in spring 2006 – and their social welfare officers when the clients were in compulsory care and then again about six months after its termi

Certain climatologically-adverse conditions in the basin of the Poopo Lake, located on the high plateau of the Bolivian Altiplano, have prevented the existence of a reliable agricultural system and the impact on the population of the area has been severe. These problems have been the main motivation in choosing this region for this particular study. However, many species of plants have somehow man

Popular Abstract in Swedish I centrum för avhandlingen står det fotografiska porträttet. Min utgångspunkt har varit att kombinera olika teorier om kön med intresset för fotografi. Syftet har varit att visa hur fotografiska porträtt under perioden 1850-1910 i olika sociala och kulturella relationer medverkade till att formulera skilda bilder av vad en kvinna var. För att kunna göra det jämför jag f"Visiting Reality: Photography and Gender at the End of the Nineteenth Century" In the centre of the dissertation stands the photographic portrait. My point of departure has been to combine different theories of gender with an interest in photography. The aim has been to show how, during the period of 1850 to 1910, photographic portraits in different social and cultural relations contributed to f

The Marieberg porcelain factory, situated on the island of Kungsholmen in Stockholm, existed between 1758 and 1788. The aim of this study has been to investigate the manufacture of tiled stoves at Marieberg. The first question I wanted to answer was: how many were actually produced? The few documents from the period that have survived show that Marieberg must have had continuous production of tile

Mutations in the TP53 tumor suppressor gene have been shown to significantly correlate with poor prognosis in endometrial cancer. In the present study we have evaluated a luminometric immunoassay (LIA) for quantitative estimation of TP53 protein expression in 65 cytosol preparations from endometrial cancer, previously analyzed for mutations in TP53 exons 4-10. LIA showed high (greater than or equa

Popular Abstract in Swedish I denna avhandling presenteras en ny typ av röntgenkälla baserad på ett laser-producerat plasma. Röntgenstrålning alstras genom att fokusera laserpulser på ett strålmål. Energin i de enskilda laserpulserna blott är cirka 150 mJ, men tack vare den extremt korta pulstiden 100 fs (10E-13 s), blir laserns toppeffekt mer än 1 TW (10E12 W). Den extremt intensiva laserstrålninA laser-produced plasma was generated by focusing 100 fs laser pulses, with an energy of 150 mJ, onto metal targets. The laser intensity was expected to reach 10E17 W/cm2. Radiation was emitted from the created plasma, with photon energies extending up to the MeV regime. The laser-based X-ray source was optimised, with the purpose of making it a realistic source of hard X-rays (>10 keV). Dedicated

OBJECTIVES: To compare different forms and ratios of serum prostate-specific antigen (PSA) to determine which form or ratio provides optimal diagnostic specificity and sensitivity in distinguishing between benign prostatic hyperplasia (BPH) and clinically localized prostate cancer. METHODS: Serum samples were obtained from 47 patients with BPH and 39 with clinically localized prostate cancer. Pati

In a population-based case-control study in Sweden on multiple myeloma, the occurrence of different diseases in relatives, particularly hematologic malignancies and different types of cancer, was investigated. Through a questionnaire mailed to all living subjects, i.e. cases and controls, and to the next-of-kin for deceased subjects, information was obtained on malignant and certain other diseases

Background: Anal cancer is a rare disease, which might be the reason for the "one size fits all" approach still used for radiotherapy target contouring. To refine and individualize future guidelines, detailed and contemporary pattern of recurrence studies are needed. Methods: Consecutive anal cancer patients, all treated with curative intent intensity-modulated radiotherapy (IMRT), were retrospect

I 24 kap. 10 § a-e IL regleras begränsningen i avdragsrätten för ränta på vissa koncerninterna skulder. Reglerna framarbetades i samband med de av Skatteverkets konstaterade skatteflyktsförfaranden som skedde i anslutning till avdrag för koncerninterna ränteutgifter. Skatteverket har försökt att komma åt transaktionerna genom att tillämpa skatteflyktslagen men har inte haft framgång eftersom skattThe Income Tax Act Chapter 24 Section 10 a-e deals with restrictions of interest deductions for certain dividends. The regulations were worked out in connection with the established tax evasion procedures that occurred together with deductions for intergroup interest expenses. The Swedish Tax Agency has attempted to get hold of the transactions by applying the Law Against Tax Evasion, but have not

The purpose of this study was to examine the collaboration between organizations that care for mentally retarded persons with added psychiatric problems when they have the need of institutional care in the psychiatry. I have both looked at which kinds of collaboration there are and then looked closer on the coordinated care plan. I’ve also looked at how the organizations adjust themselves after th

The fight about the syringe - a discourse analysis of the needle exchange debate The debate about needle exchange had been going on for twenty years in Sweden when the Act (2006:323) on the exchange of needles and syringes was introduced in 2006. But still the syringe exchange program is only implemented in Skåne. The purpose of this study was to, with a social constructionist and discourse analy

The purpose of this work is to map what musical praise and worship means to different church members. What do they think of today's worship? Are there music styles or any instruments that are not suitable? What do the members think of contemporary Christian music and the regular traditional music in church? Do we need to make changes or not? How does the Christian Music affect their spiritual
