Inbreeding depression is a key factor influencing mating system evolution in plants, but current understanding of its relationship with selfing rate is limited by a sampling bias with few estimates for self-incompatible species. We quantified inbreeding depression () over two growing seasons in two populations of the self-incompatible perennial herb Arabidopsis lyrata ssp. petraea in Scandinavia.

Aims: The general objective was to further elucidate thromboembolic disease in children and thereby help improve the care of these patients. More specific aims were as follows: to determine what children are affected by thrombosis; to discern any gender or age differences related to thrombosis; to identify prothrombotic risk factors; to ascertain whether autoantibodies against coagulation proteins

Studies on growth of the small intestine have mostly concentrated on crypt hyperplasia rather than crypt fission (CF). The process of crypt bifurcation has been identified in rodents and humans but not in swine. The main aims of this study were: 1) to investigate quantitatively crypt fission in the small intestine mucosa of pigs of different age-groups and 2) to assess the effect of colostrum and

We study the properties of impersonal null-subjects, in particular in Icelandic, exploring the idea that such elements are constructed in syntax (rather than being lexical pronouns deleted in PF). In addition, we discuss the cross-linguistic distribution of impersonal null-subjects.

Enflo K. and Hjertstrand P. Relative sources of European regional productivity convergence: a bootstrap frontier approach, Regional Studies. This paper addresses the issue of Western European regional productivity growth and convergence by means of data envelopment analysis (DEA), decomposing labour productivity into efficiency change, technical change and capital accumulation. The decomposition s

Prominent in the sky, but not visible to humans, is a pattern of polarized skylight formed around both the Sun and the Moon. Dung beetles are, at present, the only animal group known to use the much dimmer polarization pattern formed around the Moon as a compass cue for maintaining travel direction. However, the Moon is not visible every night and the intensity of the celestial polarization patter

Numerous studies have investigated causes of warfarin dose variability in adults, whereas studies in children are limited both in numbers and size. Mechanism-based population modelling provides an opportunity to condense and propagate prior knowledge from one population to another. The main objectives with this study were to evaluate the predictive performance of a theoretically bridged adult warf

A spatio-temporal model is constructed to interpolate yearly precipitation data from 1982 to 1996 over the African Sahel. The precipitation data used in the analysis comes from the Global Historical Climatology Network. The spatio-temporal model is based on a Gaussian Markov random field approach with AR(1)-dependence in time and a spatial component modeled using an approximation of a field withMa

Populärvetenskaplig artikel om Raoul Wallenberg och hans gärning i Budapest 1944–45, då han räddade tusentals judar undan förintelsen.

He-3 was a popular material in neutrons detectors until its availability dropped drastically in 2008. The development of techniques based on alternative convertors is now of high priority for neutron research institutes. Thin films of B-10 or (B4C)-B-10 have been used in gas proportional counters to detect neutrons, but until now, only for small or medium sensitive area. We present here the multi-

Recent matrix isolation (p-H-2, Ne, Ar, Kr) studies of water clusters made in Lund are reviewed. Gas phase positions of water cluster bands are estimated from matrix data. Intermolecular spectra of several isotopomers of the water dimer have been obtained, and approximate band strengths have been measured. Acceptor switching of the water dimer has been observed in matrices. A few intermolecular vi

Emerging multiculturalism in China's metropolitan areas implies people's frequent engagement in intercultural contacts and, therefore, creates a need for a mutual acculturation between the migrants and the host society. This research aimed to contribute to the study of immigrant adjustment in China by exploring the patterns of dietary acculturation among Russian immigrants residing in Beijing. The

Gene expression profiling (GEP) has significantly contributed to the elucidation of the molecular heterogeneity of multiple myeloma plasma cells (MMPC) and only recently it has been recommended for risk stratification. Prior to GEP MMPC need to be enriched resulting in an inability to immediately freeze bone marrow aspirates or use RNA stabilization reagents. As a result in multi-center MM trials

We calculate spin relaxation times due to spin-orbit-mediated electron-phonon interactions for experimentally accessible semiconductor quantum ring and dot architectures. We elucidate the differences between the two systems due to different confinement. The estimated relaxation times (at B = 1 T) are in the range between a few milliseconds to a few seconds. This high stability of spin in a quantum

Background: Prostate-specific antigen (PSA) is widely used to detect prostate cancer. The low positive predictive value of elevated PSA results in large numbers of unnecessary prostate biopsies. We set out to determine whether a multivariable model including four kallikrein forms ( total, free, and intact PSA, and human kallikrein 2 (hK2)) could predict prostate biopsy outcome in previously unscre

Background: The sural nerve is the most commonly used nerve for grafting severe nerve defects. Our aim was to evaluate subjective outcome in the lower leg after harvesting the sural nerve for grafting nerve defects. Methods: Forty-six patients were asked to fill in a questionnaire to describe symptoms from leg or foot, where the sural nerve has been harvested to reconstruct an injured major nerve
