The cross section for the diffractive deep-inelastic scattering process ep -> eX(P) is measured, with the leading final state proton detected in the H1 Forward Proton Spectrometer. The data analysed cover the range x(P) < 0.1 in fractional proton longitudinal momentum loss, 0.08 < vertical bar t vertical bar < 0.5 GeV-2 in squared four-momentum transfer at the proton vertex, 2 < Q(2) < 50 GeV2 in
Abstract in Spanish Este estudio aborda el movimiento de retorno entre los inmigrantes establecidos en Suecia y que tienen entre 51 y 80 años de edad. Una cuestión importante se refiere a la repercusión de la jubilación en la migración de retorno. Algunas circunstancias vinculadas con el abandono del mercado laboral sugieren una mayor tendencia al retorno, por ejemplo la transición del cobro de unThis study deals with return migration among immigrants in Sweden who are between 51 and 80 years old. An important question regards the impact of retirement on return migration. Some circumstances connected to the withdrawal from the labour market suggest an increased propensity to return, such as the transition from a wage income to a pension, which weakens the link between place of residence an
This paper concerns transient sorption measurements in two intervals (54 to 75% and 75 to 84% relative humidity) made on samples of pine, spruce, ash, aspen, cherry, and willow, with the flow in different directions. In the lower interval, the sorption behavior is quite Fickian; but in the higher interval, it is largely governed by other processes—e.g., the slow sorption in the cell walls. Differe
Abstract in French Ce volume de PERLES est consacré à une comparaison de l’acquisition et de la production de la morphologie flexionnelle à travers de différents corpus.
Background The aim of this study was to describe the Variable anatomy in the anastomosis between the umbilical arteries for better understanding of the physical characteristics of the umbilical Row velocity waveform (FVW). Methods. The arterial system of 67 placentas from pregnancies with normal umbilical FVW and resulting in a full-term AGA infant was visualized by angiography. The method allowed
The thesis deals mainly with modelling sea surface dynamics. We consider two different scales. The short-term scale,known as sea state, in which the sea surface over a restricted time period and space can be modelled as a stationary random field, and the long-term scale in which we study the evolution of wave characteristics like the significant wave height $H_s$, over long periods of time and at
In recent years, value for money in health care has become of increasing concern. There are various ways to perform an economic evaluation, the most simple being a cost-effectiveness analysis, where differences in costs will influence the choice between methods. Cost-utility and cost-benefit analyses represent more advanced forms of economic evaluations. In this cost-effectiveness analysis, the fo
We examined the influence of female age, male age, and pair-bond duration on start of egg-laying, clutch size, and number of young fledged in the Lesser Spotted Woodpecker (Dendrocopos minor). We also attempted to disentangle the relative influence of individual age and pair-bond duration on reproduction, because the effect of those factors may be confounded. Brooding performance improved with age
We compare the results of electrically detected magnetic resonance in a 2D electron gas in Si/SiGe quantum wells with transport and magnetic resonance measurements on ferromagnetic Ga1-xMnxAs. The results lead us to the conclusion that observation of electrically detected magnetic resonance is possible only in the case of a slow spin relaxation, where the microwave resonant absorption leads to a n
Kaposi's sarcoma occurs as a multicentric proliferation of endothelial cells. A lesion may progress through several histologic stages, culminating in a lesion consisting of spindle cells with marked nuclear atypia that may be indistinguishable from angiosarcoma. To assess the relationship between the nuclear DNA content and the stage, 29 paraffin-embedded biopsy specimens from 25 cases of Kaposi's
A novel immunoassay (PINC-ELISA) was designed using proteinase inhibitors of the cystatin superfamily (PINC) in the solid phase, to promote the selective capture of cysteine proteinases. The method was applied in the identification of papain-like antigens from parasitic protozoa. PINC of human origin, namely recombinant cystatin C (r-cystatin C) or low molecular weight kininogen were used in the a
Human papillomaviruses (HPVs) of the genera Betapapillomavirus and Gammapapillomavirus are common on human skin. Sequencing of subgenomic amplicons of cutaneous HPVs has revealed a large number of novel putative HPV types within these genera. Phylogenetic analysis based on these amplicons revealed 133 putative HPV types with <90% sequence identity to any known HPV type or to each other. As there a
Sixty guinea pigs were exposed to a steady-state broadband noise with a falling frequency spectrum. The sound-pressure level was varied between 96 and 117 dB SPL, and the duration of the exposure was varied from 3 to 12 h. After 4-5 weeks, the auditory thresholds were determined by electrocochleography at 14 frequencies, and the results were compared with a control group. With increasing sound-pre
Flower color can be a major determinant of plant fitness, not only because of preferential visitation by pollinators but also because of pleiotropic relationships between the expression of floral pigments and biochemically related compounds that influence vegetative performance variables. Different environments may therefore favor different pigmentation phenotypes. We examined whether spatially va
