The Starlings Sturnus vulgaris breeding in sixteen nest-box groups, three in northern and thirteen in southern Sweden, were monitored in 1988-2003. Date of the first egg was found to correlate with both latitude and elevation when all sites were included (13 degrees of latitude; 5-430 m elevation). Restricting the analysis to only the south Swedish sites (4 degrees of latitude; 5-230 m elevation),
Let π:M→B be a horizontally conformal submersion. We give necessary curvature conditions on the manifolds M and B, which lead to non-existence results for certain horizontally conformal maps, and harmonic morphisms. We then classify all such maps between open subsets of Euclidean spaces, which additionally have totally geodesic fibres and are horizontally homothetic. They are orthogonal projection
PURPOSE: To describe the introduction and performance of proton MR spectroscopy (1H-MRS) in the daily routine of a modern standard MR unit. MATERIAL AND METHODS: Over an 8-month period, 52 patients with brain lesions were studied with 1H-MRS, using SE and STEAM sequences for chemical-shift imaging and single-volume spectroscopy. The quality of the spectra was graded from 1 (best) to 3, and the mai
[1] Transport of nonaqueous phase liquids (NAPLs) in soils is becoming an increasingly serious threat to the environment. Detection and observation of these substances are thus an increasingly important issue. During recent years, studies have used the apparent dielectric constant (K-a) measured by time domain reflectometry (TDR) for determining the saturation of NAPLs (theta(NAPL)) in soils (m(3)
III-V nanowires have been fabricated by metal-organic vapor-phase epitaxy without using Au or other metal particles as a catalyst. Instead, prior to growth, a thin SiOx layer is deposited on the substrates. Wires form on various III-V substrates as well as on Si. They are nontapered in thickness and exhibit a hexagonal cross-section. From high-resolution X-ray diffraction, the epitaxial relation b
OBJECTIVES: To investigate a broad range of occupational, hobby, and lifestyle exposures, suggested as risk factors for Philadelphia chromosome positive (Ph+) chronic myeloid leukaemia (CML). METHODS: A case-control study, comprising 255 Ph+CML patients from southern Sweden and matched controls, was conducted. Individual data on work tasks, hobbies, and lifestyle exposures were obtained by telepho
OBJECTIVE: To evaluate the sensitivity and specificity of CSF-tau in clinical practice as a diagnostic marker for AD compared with normal aging and depression, to study the stability of CSF-tau in longitudinal samples, and to determine whether CSF-tau levels are influenced by different covariates such as gender, age, duration or severity of disease, or possession of the APOE-epsilon4 allele.

The distribution of polarization in the overcast sky has been practically unknown. Earlier the polarization of light from heavily overcast skies (when the Sun's disc was invisible) has been measured only sporadically in some celestial points by point-source polarimetry. What kind of patterns of the degree p and angle a of linear polarization of light could develop after transmission through a thic
X-ray photoelectron spectroscopy (XPS) was used to study the distribution of elements and main wood components (cellulose and lignin) within the wood and at the bark/wood interface of a living hybrid aspen stem. The hybrid aspen was grown upright in a greenhouse and then tilted at similar to45degrees to induce tension wood formation and upright bending of the stem. The wood between the pith and th
The possibility that long-term atmospheric nitrogen pollution and fertilization of forest soil may serve as a basis for adaptation for enhanced transformation rates of NO3- and NH4+ in soil. bacteria was elucidated in a laboratory bioassay. Bacteria extracted from soils that had been fertilized at various rates for the last 30 yr were characterised with respect to their capability to reduce or oxi
Vascular endothelial growth factor (VEGF) stimulates angiogenesis by activating VEGF receptor-2 (VEGFR-2). The role of its homolog, placental growth factor (PlGF), remains unknown. Both VEGF and PlGF bind to VEGF receptor-1 (VEGFR-1), but it is unknown whether VEGFR-1, which exists as a soluble or a membrane-bound type, is an inert decoy or a signaling receptor for PlGF during angiogenesis. Here,
DNA microarrays can be used to identify gene expression changes characteristic of human disease. This is challenging, however, when relevant differences are subtle at the level of individual genes. We introduce an analytical strategy, Gene Set Enrichment Analysis, designed to detect modest but coordinate changes in the expression of groups of functionally related genes. Using this approach, we ide
This article reports the results of structural studies of poly (-benzyl-L-glutamate) (PBLG) layers self-assembled from dilute solutions in organic solvents on mica surface. Polarized dynamic light scattering and atomic force microscopy were used to study polymer properties in solutions and on the surface. The hierarchy of self-assembly from PBLG solutions in different solvents was investigated as
A systematic review of radiation therapy trials in several tumour types was performed by The Swedish Council of Technology Assessment in Health Care (SBU). The procedures for evaluation of the scientific literature are described separately (Acta Oncol 2003; 42: 357-365). This synthesis of the literature on radiation therapy for uterine cancer is based on data from one randomized study Moreover, da
Vehicle design is characterized by a high number of compromises. The special role of human factors in the process is to ensure that the compromises do not occur at the expense of the driver and passengers. Within the automotive industry there is a need for the development of inexpensive and efficient ergonomic tools, facilitating a fast and cost effective car development process as well as discuss
Popular Abstract in Swedish Denna avhandling består av ett introduktionskapitel, följt av tre kapitel i vilka individens betalningsvilja för att reducera väg- och personbildödsrisken skattas, baserat både på observerade och hypotetiska val. I kapitel 2 används den hedoniska regressionstekniken på den svenska personbilsmarknaden för att skatta värdet av trafiksäkerhet. Resultaten från studien visaThe thesis consists of an introductory chapter, followed by three chapters in which willingness to pay (WTP) for a reduction in car- and road-mortality risk is estimated using both revealed- and stated-preference methods. In chapter 2 the hedonic regression technique is used to estimate the value of traffic safety, using information from the Swedish market for automobiles. The results from the st
Popular Abstract in Swedish Små kyrkor i länder som domineras av andra religioner är ofta beträngda idag. I Malaysia växer sig Islam starkt, och islamistiska rörelser med terroristiska metoder omger landet på alla sidor. Samtidigt har även Buddhism och Hinduism fått nytt liv. Genomgående märks en skärpt hållning visavi den kristna kyrkan och en tilltagande kritik av proselytism. Från Väst finns inProtestantism in Malaysia is in many cases the result of labour migration from China and India in the 19th and 20th Centuries. Under the British colonial administration, it enjoyed a certain degree of protection. Furthermore, in the 20th Century, many Western missions started work in Malaysia often in order to strengthen and expand the ministry of existing denominations. This was particularly true
