Space weather events in July 1982 and October 2003 and the effects of geomagnetically induced currents on Swedish technical systems

In this paper, we analyse in detail two famous space weather events; a railway problem on 13-14 July 1982 and a power blackout on 30 October 2003. Both occurred in Sweden during very intensive space weather storms and each of them a few years after the sunspot maximum. This paper provides a description of the conditions on the Sun and in the solar wind leading to the two GIC events on the ground.

Coreceptor change appears after immune deficiency is established in children infected with different HIV-1 subtypes

Change of HIV-1 coreceptor use has been connected to progression of disease in children infected with HIV-1, presumably subtype B. It has not been possible to discern whether the appearance of new viral phenotypes precedes disease development or comes as a consequence of it. We studied the evolution of coreceptor use in HIV-1 isolates from 24 vertically infected children. Their clinical, virologic

The Performativity of the Service Management Discourse - “Value Creating Customers” in Health Care

PURPOSE: The formation and spreading of market-, management- and individual-rights discourses into society, as well as the movement of consumerism, have paved the way for a transformation of the linguistic usage. The transformation suggests that the view of the care seeker has shifted from a waiting patient, via a consumer to a customer creating value. Another example of the process is that the fo

Interaction between smoking, GSTM1 deletion and colorectal cancer: results from the GSEC study

Cigarette smoking has inconsistently been associated with an increased risk of colorectal cancer. One of the enzymes responsible for the detoxification of the carcinogenic compounds present in tobacco smoke is glutathione S-transferase-mu (GST-mu). The gene that codes for this enzyme is GSTM1. In this study, we evaluated the associations and interaction between GSTM1 deletion, smoking behaviour an

Marital life course events and smoking behaviour in Sweden 1980-2000

The protective effect of marriage on smoking has been extensively established in the literature. However, less is known about the dynamics of how smoking behaviour is connected to various marital life course events, and whether there are any gender discrepancies in this respect. In this article the connection between the marital life course and smoking is analysed from a stress-related perspective

Amplitude-integrated EEG (aEEG) predicts outcome after cardiac arrest and induced hypothermia.

Objective To evaluate the use of continuous amplitude-integrated EEG (aEEG) as a prognostic tool for survival and neurological outcome in cardiac arrest patients treated with hypothermia. Design Prospective, observational study. Setting Multidisciplinary intensive care unit in a university hospital. Intervention Comatose survivors of cardiac arrest were treated with induced hypothermia for 24 h. A

Spinal sensorimotor transformation: Relation between cutaneous somatotopy and a reflex network

The projection of primary afferents onto spinal interneurons constitutes the first step in sensorimotor transformations performed by spinal reflex systems. Despite extensive studies on spinal somatotopy, uncertainties remain concerning the extent and significance of representational overlap and relation to spinal reflex circuits. To address these issues, the cutaneous projection from the hindpaw a

Common suppression pattern of eta and pi(0) mesons at high transverse momentum in Au plus Au collisions at root SNN=200 GeV

Inclusive transverse momentum spectra of eta mesons have been measured within p(T)=2-10 GeV/c at midrapidity by the PHENIX experiment in Au+Au collisions at root s(NN) = 200 GeV. In central Au+Au the eta yields are significantly suppressed compared to peripheral Au+Au, d+Au, and p+p yields scaled by the corresponding number of nucleon-nucleon collisions. The magnitude, centrality, and p(T) depende

Organic fouling of electrodialysis membranes with and without applied voltage

In this investigation organic fouling of ED membranes was studied with and without applied voltage. Fouling without the application of voltage, i.e., adsorption, was observed as an increase in the membrane resistance, and fouling with the application of voltage, i.e., conventional ED, was observed as an increase in the voltage drop across the membrane. Experiments were performed with three differe

PTSD and ADHD: underlying factors in many cases of burnout

Objective: To analyse the extent to which traumatic life events, post-traumatic stress disorder (PTSD) and the neuropsychiatric disorder attention deficit hyperactivity disorder (ADHD) can be contributors associated with burnout and the long-term sick leave that results from it. Subjects: Sixty-two individuals on long-term sick leave due to stress-related poor health and burnout, and 83 working in

Skipping the Baltic: the emergence of a dichotomy of alternative spring migration strategies in Russian barnacle geese

Since the early 1990s, an increasing proportion of barnacle geese, Branta leucopsis, bound for breeding sites in the Russian Arctic delay their departure from the wintering quarters in the Wadden Sea by 4 weeks. These late-migrating geese skip spring stopover sites in the Baltic traditionally used by the entire population. Individual geese from an arctic colony tracked by satellite or light-level

Acute pancreatitis in Soweto, South Africa: Relationship between trypsinogen load, trypsinogen activation, and fibrinolysis

Objective: It is not known why acute pancreatitis in Soweto, South Africa, pursues an aggressive course. We sought clues from circulating trypsinogen load at admission as marker of initial acinar injury, trypsinogen activation using the carboxypeptidase B activation peptide as surrogate, proteinase inhibitors, the coagulation-fibrinolysis axis, indicators of inflammation, oxidative stress markers,

Does It Really Matter Where You Live? A Panel Data Multilevel Analysis of Swedish Municipality Level Social Capital on Individual Health-Related Quality of Life

We test whether individual health status is related to area-level social capital measured by rates of voting participation in municipal political elections, controlling for personal characteristics, where health status is measured by mapping responses to interview survey questions into the generic health-related quality of life measure (HRQoL) the EQ-5D in order to derive the health state scores.

Inhibition of propylene oxidation to acrylic acid by amorphous overlayers on MoV(Nb)TeO based M2 catalysts

One of the most effective catalysts for the selective oxidation of propane to acrylic acid (AA) and ammoxidation to acrylonitrile (AN) is the MoV(Nb,Ta)(Te,Sb)O system, comprised of two phases, with M1 the major catalyst and M2 the co-catalyst in symbiosis with M1, converting intermediately formed propylene to the respective desired end products. An improvement in either phase should enhance the o

Abdominal manifestations of non-Hodgkin's lymphomas

25 children (18 boys and 7 girls) were treated for non-Hodgkin's lymphomas (NHL) during 1982-1990. The age at diagnosis was 2-15 years. Five of the 25 children died. Of the 25 children 6 patients had the diagnosis of intraabdominal NHL. The presenting abdominal symptoms for these 6 patients were abdominal pain in 4 cases, nausea 3, abdominal distention 2, icterus 1 and diarrhoea 1. Four of the 6 p

Levels of apolipoprotein M are not associated with the risk of coronary heart disease in two independent case-control studies

Apolipoprotein M (apoM), a 25 kDa plasma protein belonging to the lipocalin protein family, is predominantly associated with HDL. Studies in mice have suggested apoM to be important for the formation of pre-beta-HDL and to increase cholesterol efflux from macrophage foam cells. Overexpression of human apoM in LDL receptor-deficient mice reduced the atherogenic effect of a cholesterol-rich diet. Th

Chlorhexidine for prevention of neonatal colonization with group B streptococci. V. Chlorhexidine concentrations in blood following vaginal washing during delivery

Chlorhexidine 2 g/l was applied to the vagina of 96 women during delivery, whereas 28 served as controls. Both groups were given a shower using a chlorhexidine soap, and outer washing of the outer anogenital tract was also performed in all patients using chlorhexidine 2 g/l. Using a gas chromatographic method with a detection limit of 10 ng chlorhexidine per ml blood, 10-83 ng/ml was demonstrated
