We investigated the orientation of juvenile pied flycatchers, Ficedula hypoleuca, during autumn migration in south Sweden using orientation cage experiments, to study the relative importance of visual and magnetic information at sunset. We performed cage tests under 12 experimental conditions that manipulated the geomagnetic and visual sunset cues available for orientation: natural clear skies in

Azimuthal correlations of jet-induced high-p(T) charged hadron pairs are studied at midrapidity in Au+Au collisions at root s(NN)=200 GeV. The distribution of jet-associated partner hadrons (1.0 < p(T)< 2.5 GeV/c) per trigger hadron (2.5 < p(T)< 4.0 GeV/c) is found to vary with collision centrality, in both shape and yield, indicating a significant effect of the nuclear collision medium on the jet

Objectives: The study examined the relation between daily workhours and the occurrence of neck-shoulder or back pain in physically demanding care work. Methods: Unpublished data were obtained from three intervention projects in care institutions. The projects had been conducted independently in Oslo (46 participants, 175 referents before and 158 referents after the intervention), Helsingborg (60

The character and quantity of dissolved organic carbon (DOC) were studied in nine small boreal streams and adjacent soils during two years, with focus on the spring snowmelt period. The streams cover a forest-wetland gradient, spanning from 0% to 69% wetland coverage. Lower values of the absorbance ratio measured at 254 nm and 365 nm (A(254)/A(365)), in both soil plots and streams, indicated that

The impedance at frequencies of 1-1000 kHz and dynamic bending storage modulus measured by the vibrating reed method were compared for potato tuber tissue, which had been processed by various methods. Raw potato tuber tissue strips were either heated for 30 min up to 100°C or frozen-thawed. Some samples were osmotically dehydrated in a mannitol solution up to a concentration of 0.7 mol/l. The elec

Amplified fragment length polymorphisms (AFLP) are dominant markers frequently used to build linkage maps where heterozygosity could be inferred by a backcross breeding strategy. In the present study, we describe the utilization of an unmanipulated great reed warbler, Acrocephalus arundinaceus pedigree to infer heterozygous genotypes of AFLP markers in order to map these markers to a partial linka

Aims: To study the impact of social participation, trust, and the miniaturization of community, i.e. high social participation/low trust, on the risk of high alcohol consumption. Methods: The Scania 2000 public health survey is a cross-sectional, postal questionnaire study. A total of 13 604 persons aged 18–80 years were included. A logistic regression model was used to investigate the association

The objective of the present study was to determine whether a systematic optimization of Morris water maze (mwm) testing parameters could reveal a significant role of the septohippocampal cholinergic system in spatial working memory. Young adult rats were lesioned using 192 IgG-saporin infused bilaterally into the medial septum. Lesions were near complete as measured by choline acetyltransferase (

In the present study, the objective was to evaluate the long-term metabolic impact of adding lactic acid to a bread-based diet in obese, hyperinsulinaemic Zucker (fa/fa) rats. All diets were based on a white wheat bread, and the lactic acid was added either prior to, or after the baking process. In addition, a diet with addition of Lactobacillus plantarum 299v was included to investigate the possi

This work describes a mediated amperometric method for simultaneous real-time probing of the NAD(P)H availability in two different phenotypes, fermentative and respiratory, of the phosphoglucose isomerase deletion mutant strain of S. cerevisiae, EBY44 [ENY.WA-1A pgi1-1D::URA3], and its parental strain, ENY.WA-1A. The developed method is based on multichannel detection using microelectrode arrays.

Activated protein C inhibits the procoagulant function of activated factor V (FVa) through proteolytic cleavages at Arg-306, Arg-506, and Arg-679. The cleavage at Arg-506 is kinetically favored but protected by factor Xa (FXa). Protein S has been suggested to annihilate the inhibitory effect of FXa, a proposal that has been challenged. To elucidate the effects of FXa and protein S on the individua

Testing for prostate-specific antigen ( PSA) has profoundly affected the diagnosis and treatment of prostate cancer. PSA testing has enabled physicians to detect prostate tumours while they are still small, low-grade and localized. This very ability has, however, created controversy over whether we are now diagnosing and treating insignificant cancers. PSA testing has also transformed the monitori

Radical copolymerization of acrylamide (Am) (90 mol%) with N-acryloyl-m-aminophenylboronic acid (NAAPBA) (10 mol%) carried out on the surface of glass slides in aqueous solution and in the absence of chemical cross-linkers, resulted in the formation of thin semitransparent gels. The phenylboronic acid (PBA) ligand density was ca. 160 micromol/ml gel. The gels exhibited a macroporous structure and

Parentage of 201 young (from 44 broods) in a population of Sedge Warblers Acrocephalus schoenobaenus in South Central Sweden, 1990-1992, was determined by using multilocus DNA fingerprinting. The frequency of extra-pair young (EPY) was 7.5% and they occurred in 23% of the broods. For 11 out of 15 extra-pair young we could identify the true father; in all of the cases he was a close neighbour. Amon

The globular cluster M15 was observed on three occasions with the High Resolution Camera on- board Chandra in 2001 in order to investigate the X- ray source population in the cluster centre. After subtraction of the two bright central sources, four faint sources were identified within 50 arcsec of the core. One of these sources is probably the planetary nebula K648, making this the first positive

This paper describes and analyses a community of disabled people in Sweden that use an online forum to discuss personal assistance issues. The forum is a community of practice (CoP) that has its roots in everyday living with personal assistance. The contributions to the forum were studied over a 41/2 year period, including a total of 2755 postings from 146 persons. The levels of the CoP learning s

Neutral pion transverse momentum (p(T)) spectra at midrapidity (|y| less than or similar to 0.35) were measured in Cu + Cu collisions at root s(NN) = 22.4, 62.4, and 200 GeV. Relative to pi(0) yields in p + p collisions scaled by the number of inelastic nucleon-nucleon collisions (N-coll) the pi(0) yields for p(T) greater than or similar to 2 GeV/c in central Cu + Cu collisions are suppressed at 6

Aromatic lactose 2-O-esters were synthesized and used to probe arene-arginine interactions with the galectin family of proteins. They were found to be low mu m inhibitors of galectin-1, -3, and -9N-terminal domain and moderate inhibitors of galectin-7, but not inhibitors of galectin-8N-terminal, which locks an arginine residue close to the critical, esterified lactose 2-O-position. Molecular model

Mo-V-Nb-Te-oxide catalysts with nominal metal compositions equal to those of M1, M2, and a mixture of the M1 and M2 phases were prepared in neat and sol-diluted forms. The latter catalysts were prepared with 30 wt% of Al2O3, SiO2, or TiO2 sol. All catalysts were characterized by BET, XRD, and TPR and tested for the respective ammoxidation of propane and propene. XRD showed that dilution with SiO2
