Chronic non-A, non-B, non-C hepatitis: is hepatitis G/GBV-C involved?

BACKGROUND: Hepatitis G virus/GBV-C is a recently discovered virus, and its relevance in chronic hepatitis is still debated. METHODS: We have previously described 127 long-term-studied and well-characterized patients with chronic non-A, non-B hepatitis (NANBH). Ninety-one (71.7%) were positive for hepatitis C virus antibodies (anti-HCV) in a first-generation anti-HCV enzyme-linked immunosorbent as

Temperature effect on single chain MEH-PPV spectra

We report single molecule photoluminescence spectra of poly[2-methoxy-5-(2'-ethyl-hexyloxy)-1,4-phenylene vinylene] (MEH-PPV) in PMMA-matrix at 293 and 20 K with 90 s acquisition time. All spectra at 293 K are very similar, contrary to literature results with acquisition times < 5 s. We propose that fluctuations of conformations with distinct emission properties cause broadening of the spectra and

Inelastic leptoproduction of J/psi mesons at HERA

The leptoproduction of J/psi mesons is studied in inelastic reactions for four momentorri transfers 2 < Q(2) < 100GeV(2). The data were taken with the H1 detector at the electron proton collider HERA and correspond to an integrated luminosity of 77 pb(-1). Single differential and double differential cross sections are measured with increased precision compared with previous analyses. New leading o

The influence of ventilation systems on water depth penetration of emergent macrophytes

1. Roots of emergent macrophytes depend on oxygen transported from aerial parts by diffusion and, in some species, by pressurised ventilation. The aim of this study was to determine if species with pressurised ventilation grow in deeper water in situ than species lacking this ability. 2. Species with pressurised ventilation grew significantly deeper than species lacking pressurised ventilation, an

Polarization measurements in neutral pion photoproduction

We present measurements of the recoil proton polarization for the H-1((γ) over right arrow,(p) over right arrow)pi(0) reaction for theta(c.m.)(pi) = 60degrees-135degrees and for photon energies up to 4.1 GeV. These are the first data in this reaction for polarization transfer with circularly polarized photons. Various theoretical models are compared with the results. No evidence for hadron helicit

On the existence of harmonic morphisms from certain symmetric spaces

In this paper we give a positive answer to the open existence problem for complex-valued harmonic morphisms from the non-compact irreducible Riemannian symmetric spaces SLn (R)/SO(n), SU*(2n)/Sp(n) and their compact duals SU(n)/SO(n) and SU(2n)/Sp(n). Furthermore we prove the existence of globally defined, complex-valued harmonic morphisms from any Riemannian symmetric space of type IV.

The hoverflies (Diptera, Syrphidae) on a small farm at Linnaeus´ birthplace in the parish of Stenbrohult, Sweden

We made a detailed study of the hoverflies on a small farm in the parish of Stenbrohult, southern Sweden in 2004-2007. The study area is totally about 17 ha, consisting of 9 ha of semi-natural grasslands with both dry and wet parts (recently mainly grazed by cattle and a few horses in late summer-autumn), a few hectares of old deciduous forest dominated by Fagus, Quercus, Betula, Populus tremula,

Footwear for cold work: a field study at a harbour

A series of field studies at cold workplaces were initiated. This paper deals with a study at a harbour and the main attention is paid to the thermal responses of the feet and footwear performance. The study was carried out in February. Eight male workers were the subjects. They were selected among volunteers who carried out four different jobs in pairs. The warm winter boots were provided by the

Acute decrease of coronary flow after indomethacin delivery in newborn lambs.

Aim: To document the effects of indomethacin (IND) on coronary flow. Methods: We studied nine premature lambs during the first day of life. The gestational age varied between 132 and 134 days (term 145 days) and weight 3.1-4.7 kg. Coronary flow velocities were recorded with an intracoronary Doppler guide wire in the proximal left anterior descending coronary artery (LAD). Average peak flow velocit

A one step motion detection circuitry

A model of motion and direction detection is presented as well as results from a computer simulation of the model. The model is based on cooperative computations which allows an extremely simple architecture. Furthermore, it involves only one logical step in its computations even though Hubel and others have argued that motion detection requires at least two. This is made possible by not including

Läskulturer. Lärare, elever och litteraturläsning i grundskolans mellanår

Popular Abstract in Swedish Avhandlingen handlar om litteraturläsning och litteraturundervisning i grundskolan. Syftet är att belysa den betydelse läsning av skönlitteratur ges i skolans mellanår i början av det tjugoförsta århundradet. Forskningsfrågorna berör de mål och föreställningar om litteratur och läsning som lärare ger uttryck för och hur dessa kommer till uttryck i konkret klassrumsarbetThis dissertation explores the teaching of literature in Swedish compulsory school. The aim of the study is to elucidate different approaches to literature instruction in upper elementary school (grades 4-6, pupils aged 10-13). The research questions focus on what goals and ideas about literature and reading guide teachers and how these are carried out in pedagogical practice and classroom activit

Incidence of myocardial infarction in elderly men being treated with antihypertensive drugs: population based cohort study

OBJECTIVE: To analyse the association between use of antihypertensive treatment, diastolic blood pressure, and long term incidence of ischaemic cardiac events in elderly men. DESIGN: Population based cohort study. Baseline examination in 1982-3 and follow up for up to 10 years. SETTING: Malmo, Sweden. SUBJECTS: 484 randomly selected men born in 1914 and living in Malmo during 1982. MAIN OUTCOME ME

Verb serialization in Kammu

This paper presents the different kinds of serial verb constructions found in Kammu (a Mon-Khmer language spoken in northern Laos). Special focus is placed on how diagnostic tests (interrogative constructions, irrealis constructions and the scope of negation) can be applied to illustrate the contrast between the most prototypical serial verb constructions (e.g. directional coverbs and resultatives

Grading scale of radiographic findings in the pubic bone and symphysis in athletes.

Purpose: Radiographic abnormalities in the pubic bone and symphysis are often seen in athletes with groin pain. The aim was to create a grading scale of such radiologic changes. Material and Methods: Plain radiography of the pelvic ring including the pubic bone and the symphysis was performed in 20 male athletes, age 19-35, with long-standing uni- or bilateral groin pain. We used two control grou
