A design of sub-Kelvin single-flux quantum (SFQ) circuits with reduced power dissipation and additional cooling of shunt resistors has been developed and characterized. The authors demonstrate operation of SFQ comparators with current resolution of 40 nA at 2 GHz sampling rate. Due to improved cooling the electron temperature in shunt resistors of a SFQ comparator is below 50 mK when the bath temp
Heat transfer in gas turbine related applications is investigated by steady state liquid crystal thermography (LCT) in this thesis. The work presented includes outlet guide vane heat transfer and gas turbine internal cooling.The heat transfer on the outlet guide vane (OGV) surface and its endwall region is investigated experimentally in a linear cascade test facility. The inlet flow angle is varie
We used the in vitro regenerating frog sciatic nerve to look for effects of insulin and insulin-like growth factors I and II (IGF-I, IGF-II) on regeneration of sensory axons and on injury induced support cell proliferation in the outgrowth region. In nerves cultured for 11 days, a physiological dose (10 ng/ml, ≈ nM) of insulin or IGF-II increased ganglionic protein synthesis (by 20% and 50%, respe
Ernst Wigforss (1881−1977) was Minister of Finance in Sweden 1925−26, 1932−36, and 1936−49, and one of the great ideologists of Swedish SocialDemocracy. During 1918−36 he was also a member of the Chapter in the Diocese of Gothenburg, Church of Sweden.Before 1937, lecturers in the old grammar schools were ex officiomembers of the diocesan chapter. The agnostic Wigforss took his seat in the chapter
Background: The Swedish Program for health surveillance of preschool children includes screening of language and communication abilities. One important language screening is carried out at age 4 years as part of a general screening conducted by health nurses at child health centres. The instruments presently in use for this screening mainly focus on expressive phonology. This may result in both ov
Individuals with low levels of education systematically have worse health than those with medium or high levels of education. Yet there are few examples of attempts to summarize the evidence supporting the efficacy of interventions targeting health-related behavior among individuals with low education levels, and a large part of the literature is descriptive rather than analytical. A rapid review
A decision is the result of comparing one or more alternatives with respect to one or more criteria that we consider relevant to the decision. Decision making can be considered as one of the most important challenges that analysts and experts encounter to solve complex problems. In recent decades, different methods and algorithms have been presented to support decision making. Multi-criteria analy
Objective: Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is associated with life-threatening bleeding. This systematic review of postnatal management of FNAIT examined transfusion of human platelet antigen (HPA) selected or unselected platelets, and/or IVIg on platelet increments, hemorrhage and mortality. Study design: MEDLINE, EM
There is accumulating evidence that gestational diabetes (GDM) is a growing problem. The lack of internationally standardized diagnostic procedures prevents consistent diagnosis and the burden of GDM must be determined in country-specific studies. In southern Sweden, GDM is defined as a 2-hour capillary plasma glucose concentration of ≥10.0 mmol/L during a universal 75 g oral glucose tolerance tes
It has been suggested that those organizations which have greatest competitive success are those in which information systems strategy is seen as integral to overall business strategy. Thus, the CIO is seen as a full member of the management team, and not as someone presiding over a separate functional area which provides a service to the rest. There is a need therefore for businesses to avoid suc
OBJECTIVE: To compare the outcome following Lichtenstein open mesh technique or Shouldice repair for inguinal hernia operated on by surgeons in training. DESIGN: Prospective, randomised, trial. SETTING: District hospital, Sweden. SUBJECTS: 200 men with primary inguinal hernias. INTERVENTIONS: Lichtenstein mesh repair or Shouldice repair. MAIN OUTCOME MEASURES: Duration of operation, postoperative
Background: Smoking is probably the most important among preventable health risks. Health economic evaluation of smoking-cessation interventions, applying a lifetime perspective, is made possible by available epidemiological knowledge. The well established method of performing cost-effectiveness analyses of smoking-cessation interventions involves mathematical modelling (both deterministic and sto
The aim of this study was to determine the risk and burden of vertebral fractures judged as those coming to clinical attention and as morphometric fractures. Incidence and utility loss were computed from data from Malmo, Sweden. Clinical fractures accounted for 23% of all vertebral deformities in women and for 42% in men. The average 10-year fracture probability for morphometric fractures increase
Context: Sex steroid levels decrease with increasing age, but little is known whether this is of importance for the age-related decline in cognitive function. Design and Patients: A cross-sectional study of 50 (26 men) consecutive patients under primary evaluation of cognitive impairment (D group) and 18 (9 men) matched healthy controls (C group). Measurements: Sex steroid and precursor levels wer
Objective - People living in eastern Finland have approximate to 40% higher coronary heart disease mortality rates than western Finns. Whether this is because of genetic or environmental factors is unknown. We examined the effect of geographic family origin on subclinical atherosclerosis among young Finns. Methods and Results - As part of a longitudinal follow-up study, we measured carotid intima-
Five acute leukaemia or highly malignant lymphoma patients at a hospital in southern Sweden were interviewed about their daily living problems, their coping strategies and their opinions about the nursing care they received during the active phase of their treatment. In addition the EORTC QLQ-C30, the Global Life Quality and the Sense of Coherence scales were administered. The data were analysed f
Human galectins have functionally divergent roles, although most of the members of the galectin family bind weakly to the simple disaccharide lactose (Galss1-4Glc). To assess galectin-glycan interactions in more detail, we explored the binding of several important galectins (Gal-1, Gal-2, and Gal-3) on a glycan microarray containing hundreds of structurally diverse glycans. All three galectins exh
This article explores whether the impact of marital status on the risk of preterm birth varies in relation to marital practices in the population, defined by the proportion of out-of-marriage births. Data come from a case–control study of the determinants of preterm birth in 16 European countries (5456 cases and 8234 controls). There is a significantly elevated risk of preterm birth associated wit
Pregnancy is rare in Parkinson's disease (PD). In the literature on studies of antiparkinsonian drugs in animals during pregnancy, there are reports on malformations of the skeletal and circulatory system. However, the majority of studies in animals have not shown any teratogenicity. Amantadine has been teratogenic in rats and selegiline has caused neurochemical and behavioral alterations in rats
