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

Metastable hydrogen absorption in ejecta close to eta Carinae

Spectroscopy with the high spatial resolution of the Hubble Space Telescope (HST) reveals narrow absorption in the hydrogen Balmer lines in spectra of Eta Carinae and the nearby nebular-scattered starlight. While hydrogen Balmer absorption lines are seen in stellar photospheres and winds, we are not aware of such being seen in galactic nebulae. This exceptional case is caused by intense stellar UV

Century-scale changes of atmospheric CO2 during the last interglacial

The crucial role of atmospheric CO2 in glacial-interglacial transitions is demonstrated by recent ice-core studies that highlight the importance of accurate CO2 records for our understanding of Quaternary climate dynamics. Previous estimates of CO2 levels during the last interglacial stage (the Eemian) relied on measurements on air trapped in the Antarctic Vostok ice core. Due to uncertainties ass

Measurement of charm and beauty photoproduction at HERA using D*mu correlations

A measurement of charm and beauty photoproduction at the electron proton collider HERA is presented based on the simultaneous detection of a D*(+/-) meson and a muon. The correlation between the D* meson and the muon serves to separate the charm and beauty contributions and the analysis provides comparable sensitivity to both. The total and differential experimental cross sections are compared to

A folding variant of human alpha-lactalbumin induces mitochondrial permeability transition in isolated mitochondria

A human milk fraction containing multimeric alpha-lactalbumin (MAL) is able to kill cells via apoptosis. MAL is a protein complex of a folding variant of alpha-lactalbumin and lipids. Previous results have shown that upon treatment of transformed cells, MAL localizes to the mitochondria and cytochrome c is released into the cytosol. This is followed by activation of the caspase cascade. In this st

Enriched environment enhances recovery of motor function after focal ischemia in mice, and downregulates the transcription factor NGFI-A.

The purpose of this study was to investigate the effect of enriched environment on motor function after experimental stroke in mice, and to determine whether time in enriched environment affects functional recovery. Earlier investigations have shown that rats placed in an enriched environment after focal ischemia, remarkably improve motor function, but similar observations in mice have not been re

The Physical Foundation of the Patterning of Physical Action Verbs : A Study of Chinese Verbs

Popular Abstract in Swedish Den fysiska grunden för fysiska aktionsverbThis work is a study of verbal semantics with a focus on the discussion and illustration of the role of body parts and the semantic incorporation into verbal roots of the actions that involve various body parts. Following a general discussion of the basic issues of language construction and human body actions with the image schemas of force-dynamics presented in line with the framework of cognitiv

Augmented increase in tight junction permeability by luminal stimuli in the non-inflamed ileum of Crohn's disease

Background: Crohn's disease is associated with deranged intestinal permeability in vivo, suggesting dysfunction of tight junctions. The luminal contents are important for development of neoinflammation following resection. Regulation of tight junctions by luminal factors has not previously been studied in Crohn's disease. Aims: The aim of the study was to investigate the effects of a luminal stimu

Effects of time/temperature treatments on potato (Solanum tuberosum) starch: a comparison of isolated starch and starch in situ.

Previously, time/temperature treatments of starch have been performed mainly on starch/water systems. In this study the same time/temperature treatments were applied to starch/water systems and to potato starch in situ. Two potato varieties (Solanum tuberosum cultivars Asterix and Bintje) were used. The effect of time/temperature treatments on gelatinisation behaviour was evaluated using different

Intranasal steroids and septum perforation--an overlooked complication? A description of the course of events and a discussion of the causes

The use of intranasal steroids for the treatment of allergic and vasomotor rhinitis has doubled during the past 5 years. The number of reported cases of nasal septum perforation has increased correspondingly. The mechanism behind this is unknown, and steroid-induced septum perforation is rarely described in the literature. In order to describe the course of events and to form an idea of the extent

Review of Anne Renate Schönhagen, Die Brüder schauen sehnsüchtig nach einer ausgestreckten Bruderhand von der anderen Seite des Meeres. Das Verhältnis der schwedischen Staatskirche zum nationalsozialistischen Deutschland. Frankfurt 2000

Boken bygger på en doktorsavhandling från Mannheim 1998 och innehåller en intressant undersökning av den svenska kyrkliga verksamheten i Berlin (den officiella Victoriaförsamlingen) och Wien (den frivilliga Israelsmissionen) under den nationalsocialistiska tiden. Deras hjälpverksamhet för judar eller judekristna markerade distans till regimen och beskrivs som motstånd. Underrubriken lovar dock mer

Serum prostate specific antigen complexed to alpha 1-antichymotrypsin as an indicator of prostate cancer

Prostate specific antigen (PSA) in serum has recently been shown to occur in complex with alpha 1-antichymotrypsin and as an approximately 30 kDa. noncomplexed molecular form. We characterized PSA by 3 different assays in samples from 144 patients with benign prostatic hyperplasia (BPH) and 121 with carcinoma of the prostate. One of these noncompetitive assays measured total PSA by detecting PSA c
