Background: There are at least three broad conceptual models for the impact of the social environment on adult disease: the critical period, social mobility, and cumulative life course models. Several studies have shown an association between each of these models and mortality. However, few studies have investigated the importance of the different models within the same setting and none has been p

Results on the study of localized fluctuations in the multiplicity of charged particles and photons produced in 158A GeV/c Pb+Pb collisions are presented for varying centralities. The charged versus neutral particle multiplicity correlations in common phase space regions of varying azimuthal sizes are analyzed by two different methods. Various types of mixed events are constructed to probe fluctua

An analysis of inelastic photoproduction of J/psi mesons is presented using data collected at the ep collider HERA corresponding to an integrated luminosity of above 80 pb(-1), Differential and double I < P-t/psi(2) < differential cross sections are measured in a wide kinematic region: 60 < W-gammap < 260 GeV, 1 p(t,psi)(2) < 60 GeV2 and 0.05 < z < 0.9. where z is the fraction of the energy of the

Excited levels in As-69 were studied using the Ca-40(S-32,3p)As-69 reaction at 95 and 105 MeV beam energy. Gamma rays were detected with the EUROBALL spectrometer operated in conjunction with the Neutron Wall and the charged-particle detector array EUCLIDES. New level sequences with positive and negative parity were identified from 3p-gammagamma and gammagammagamma coincidences. Spins were assigne

In the work described in the present thesis, laser techniques for combustion engine diagnostics were developed and applied. The main techniques were laser-induced incandescence (LII) and laser-induced fluorescence (LIF), used for both flame and engine diagnostics. A novel technique was developed, one in which the relative fuel distribution, as measured by planar laser-induced fluorescence (PLIF),

These final results on e(+) e(-) W+ W- production cross-section measurements at LEP2 use data collected by the DELPHI detector at centre-of-mass energies up to 209 GeV. Measurements of total cross-sections, W angular differential distributions and decay branching fractions, and the value of the CKM element |V-cs| are compared to the expectations of the Standard Model. These results supersede all v

Heavy metals (Cd, Hg, and Pb) and stable isotopes (N-15, C-13) in crayfish (Pacifastacus leniusculus) were studied in a trophic gradient of lakes (N = 19) in southern Sweden. Trophic indicators of the lakes as total phosphorus (tot-P) varied from 5 to 93 mu g/L. The examined lakes had no known point sources of heavy metals, but the catchment areas varied from mainly forested to agricultural land.

Popular Abstract in Swedish Vill man ta en bild av något som rör sig mycket snabbt, krävs det att man använder en kort exponeringstid. Om kamerans slutare är öppen under för lång tid, hinner det man vill fotografera röra sig under tiden filmen exponeras, med resultatet att bilden blir suddig. Kemiska reaktioner där atomer och molekyler är inblandade är exempel på något som sker på väldigt kort tidWhen a low-frequency laser pulse is focused to a high intensity in a gas, the electric field of the laser may become comparable to, or even exceed, the electric field between the electrons and the nucleus in the atom. Under such conditions, through a process known as high-order harmonic generation, bursts of extreme ultraviolet radiation may be emitted, with durations in the attosecond domain (1 a

Popular Abstract in Swedish Under 1990-talet har många kommunala verksamheter ställts inför ökade kostnader av äldre- och handikappomsorgen och flera organisatoriska förändringar har genomförts. Nya problem och dess lösningar beskrivs ofta förlagda till chef- och ledarskapsområdet. Chefer och ledare inom offentlig verksamhet har under de senaste åren tillskrivits en nästan magisk betydelse för verDuring the 1990s many of the local authorities have been forced to reduce expenditure on the care of the elderly and people with disabilities, and many organisational changes have been carried out. New problems and their solutions are often related to leadership and management. This dissertation deals with three trends in the development of the organisation: The first trend is a market orientation

Treatment with alendronate ( Fosamax (R)) has been shown to significantly reduce the risk of fragility fractures. Cost-effectiveness of treatment was assessed in nine European countries in a Markov model and was generally found to be cost effective in women with a previous spine fracture. Introduction Treatment with alendronate (Fosamax (R)) reduces the risk of osteoporotic fractures at the spine,

In Sweden from 1980 to 1995 there was an overall decrease of 56% in mean length of stay (MLOS) for surgical curative breast cancer treatment. The objective of this study was to separate the possible impact of tumour size and lymph node dissemination and changes in surgical procedures. All women diagnosed (n=13 290) with breast cancer between 1982 and 1995 were selected from the Southern Swedish Tu

Objective. In published studies there is a lack of data about the risks, management and how women with autoimmune hepatitis (AIH) decide on and are advised about pregnancy. The aim of this study was to investigate how women with AIH consider pregnancies, are advised and pharmacologically treated, as well as the outcome. Material and methods. A questionnaire was mailed to 128 women with AIH diagnos

Backgound: In severe, medically unresponsive congenital hyperinsulinism (CHI), the histological differentiation of focal versus diffuse disease is vital, since the surgical management is completely different. Genetic analysis may help in the differential diagnosis, as focal CHI is associated with a paternal germline ABCC8 or KCNJ11 mutation and a focal loss of maternal chromosome 11p15, whereas a
