Psychosocial work conditions, unemployment, and generalized trust in other people: A population-based study of psychosocial health determinants
The association between psychosocial work conditions, unemployment, and generalized trust was investigated. The health survey in Skane is a cross-sectional postal questionnaire study with a 59% participation rate. A total of 5,180 persons that belonged to the work force and the unemployed were included. Logistic regression models were used to investigate the associations between psychosocial facto
Electrical characterization of thin InAs films grown on patterned W/GaAs substrates
InAs has been grown on W-GaAs patterned substrates using metal organic vapor phase epitaxy. It is shown that the W pattern guides the nucleation of the InAs on the GaAs substrate and that the islands formed may be used to embed metal features in a hybrid InAs/GaAs structure. A lower resistance (factor of 2) was measured for the hybrid structures as compared to reference structures. The reduction i
Parental care and adaptive brood sex ratio manipulation in birds.
Under many circumstances, it might be adaptive for parents to bias the investment in offspring in relation to sex. Recently developed molecular techniques that allow sex determination of newly hatched offspring have caused a surge in studies of avian sex allocation. Whether females bias the primary brood sex ratio in relation to factors such as environmental and parental quality is debated. Progre
A new distinguisher for clock controlled stream ciphers
In this paper we present a distinguisher targeting towards irregularly clocked filter generators. The attack is applied on the irregularly. clocked stream cipher called LILI-II. LILI-II is the successor of the cipher LILI-128 and its design was published in [1]. There have been no known attacks better than exhaustive key search on LILI-II. Our attack is-the first of this kind that distinguishes th
Acrylamide in food: mechanism of formation and influencing factors during heating of foods
Background: In April 2002, the Swedish National Food Administration and a scientific group at the University of Stockholm jointly announced that they had shown acrylamide to be formed during the preparation of food and found it to occur in many foodstuffs. These new findings were clearly of concern to many types of industrial food processing as well as to home cooking. The Swedish Food Federation
Stable algorithm for the stress field around a multiply branched crack
We present an algorithm for the computation of the stress field around a branched crack. The algorithm is based on an integral equation with good numerical properties. Our equation is obtained through a left regularization of an integral equation of Fredholm's first kind. Complex valued functions involving repeated products of square roots appear in the regularization. A new and effective scheme f
Palaeoenvironment and ecology of the middle Cretaceous Grebenka flora of northeastern Asia
The Grebenka flora, from the main exposure of the Albian-Cenomanian Krivorechenskaya Formation in northeastern Russia, represents a range of plant communities from pioneer to mature forest that grew close to the mid-Cretaceous North Pole (> 72degreesN). The diversity of this flora is dominated by angiosperms followed by conifers, ferns and other plant groups. The age is constrained by Ar-40/Ar-39

Protein kinase C modulation of the ethanol effect on serotonin2 receptor transduction in astrocytes
Acute ethanol exposure stimulated serotonin2 receptor signalling in cultured astrocytes. Pretreatment with the protein kinase C inhibitor H7 significantly increased the ethanol-induced potentiation of [3H]-inositol phosphates accumulation. The increase could be explained by an augmented activation of phospholipase C. The results indicate a role of PKC for the modulation of ethanol effects on cellu
Charge formation and transport in bulk-heterojunction solar cells based on alternating polyfluorene copolymers blended with fullerenes
We investigate charge formation in bulk-heterojunction solar cells based on conjugated polymers in the form of alternating polyfluorene copolymers and the methanofullerene PCBM. Using transient absorption spectroscopy we show that optimal charge formation is obtained with 20-50 wt% PCBM. This is in contrast to the maximum short circuit current density obtained at similar to 80 wt% PCBM as determin

Time constraints on exhumation of the East African Orogen from field observations and Ar-40/Ar-39 cooling ages of low-angle mylonites in Eritrea, NE Africa
Neoproterozoic high-grade metamorphic rocks of the lower to middle crust are exposed along parts of the East African Orogen (EAO). However, the mechanisms and rates of exhumation of these deep orogenic rocks remain unclear. In eastern Eritrea, the rocks of the EAO comprise two lithotectonic domains: Ghedem and Bizen. The Ghedem domain consists of low-angle mylonites among lower to middle crustal g
Smooth Termination of Rotational Bands in 62Zn: Evidence for a Loss of Collectivity
Two sets of strongly coupled rotational bands have been identified in Zn-62. These bands have been observed up to the terminating states of their respective configurations. Lifetime measurements indicate that the transition quadrupole moments in these bands decrease as termination is approached. These results establish the first terminating states of rotational bands in the A similar to 60 mass re
Speech-sound discrimination in neonates as measured with MEG
Magnetic brain responses to speech sounds were measured in 10 healthy neonates. The stimulation consisted of a frequent vowel sound [a] with a steady pitch contour, which was occasionally replaced by the vowel [i:] with a steady pitch, or the vowel [a] with a rising pitch, manifesting a change of intonation. The magnetic mismatch-negativity response (MMNm) was obtained and successfully modelled to

The heritable determinants of cartilage oligomeric matrix protein
Objective. Cartilage oligomeric matrix protein (COMP) is a cartilage matrix macromolecule. The protein is detectable in serum and has been investigated as a biomarker of osteoarthritis (OA). An association between COMP and OA has been shown, yet the precise factors governing serum levels of COMP remain unclear. The aim of this study was to determine whether genetic factors influence serum levels o

Small-x dipole evolution beyond the large-N-c limit
We present a method to include colour-suppressed effects in the Mueller dipole picture. The model consistently includes saturation effects both in the evolution of dipoles and in the interactions of dipoles with a target in a frame-independent way. When implemented in a Monte Carlo simulation together with our previous model of energy-momentum conservation and a simple dipole description of initia
