The behaviour of a male bird towards a potential mate and her clutch may depend both on his expected paternity and on the likelihood that she will produce a replacement clutch if he commits infanticide. In this study we evaluate the choices made by replacement male European starlings Sturnus vulgaris. By removing males before and during laying, we induced other males, mainly neighbours, to mate wi

Objective: To assess the reliability of 6 gait performance tests in individuals with chronic mild to moderate post-stroke hemiparesis. Design: An intra-rater (between occasions) test-retest reliability study. Subjects: Fifty men and women (mean age 586.4 years) 6–46 months post-stroke. Methods: The Timed “Up & Go” test, the Comfortable and the Fast Gait Speed tests, the Stair Climbing ascend a

Red meat and fiber rich foods are the dietary factors most consistently related to colon carcinogenesis. Although several components in these dietary sources may contribute, the biochemical mechanism by which red meat and fiber affect colorectal carcinogenesis has not yet been established. Sphingomyelin metabolism is a novel signal transduction pathway that may have an impact on colonic tumorigene

To study the role of glutathione peroxidase for lipid oxidation in meat, chicken and duck muscle were heated to an internal temperature of 60, 70 or 80 degrees C and the meats were then stored at 8 degrees C for up to 6 days. Thiobarbituric-acid-reactive substances (TBARS) and glutathione peroxidase (GSHPx) activity were measured on days 0, 1, 3 and 6. In heated muscle samples, TBARS increased dur

We discuss spectra where both a primary photoelectron and a secondary decay particle are measured. We point out the striking similarity with threshold-excited emission spectra and predict resonant peaks analoguous to those found in resonant photoemission.

Compared to monolingual first language acquisition (L1) and adult second language acquisition (aL2), relatively little research has been done on child second language acquisition (cL2). This is an unsatisfactory situation from both a practical and a theoretical point of view. The present study concerns cL2 acquisition of French and poses the question whether cL2 acquisition bears closer resemblanc

Few epidemiologic studies have examined the hypothesis that circulating androgens are involved in the development of ovarian cancer. We investigated the association between prediagnostic serum levels of androgens and sex hormone–binding globulin (SHBG) and ovarian cancer risk in a case-control study nested within the European Prospective Investigation into Cancer and Nutrition cohort. One hundred

The case is presented of a child who developed rhinoconjunctivitis, angioedema and asthma by sensitization to Sapelli wood, which was used in his father's carpentry. Positive skin-prick test, high levels of specific immunoglobulin E by ELISA and a positive conjunctival challenge test suggest a type I hypersensitivity mechanism to this wood. This is the first case report of sensitization to Sapelli

Popular Abstract in Swedish Hela livscykeln för en elektronikvara är förknippad med miljöpåverkan. I jämförelse med många andra varor är tillverkningen av elektronik och i synnerhet halvledarkomponenter mycket resurskrävande. Elektroniken ger också upphov till ett antal mycket giftiga utsläpp och avfallsströmmar, såväl från själva tillverkningen som från de uttjänta varorna. Elektronikindustrin haThe life cycle of electronic products is associated with significant environmental impacts. Compared to many other products, the production of electronics and in particular semiconductors is resource intensive and generates a number of highly toxic waste streams in manufacturing and post-consumer stages of product life cycle. Electronics manufacturing industry has been successful in reducing envir

CELSIUS Heavy-Ion Collision Silicon detector system (CHICSi) is a large solid angle, barrel-shaped detector system, housing up to 600 detector telescopes arranged in rotational symmetry around the beam axis. CHICSi measures charged particles and fragments from nuclear reactions. It operates at internal targets of storage rings. In order to optimize space and momentum-space coverage and minimize th

Popular Abstract in Swedish Vilka typer av sociala relationer var kvinnor i en tidigmodern stad inblandad i? Vilka personer bjöd man in som dopfaddrar till sina barn? Vilka var man skyldig pengar? Vilka grälade och slogs man med? Hur skilde sig kvinnors sociala relationsmönster från mäns? Hur skilde sig kvinnors relationsmönster åt beroende på deras sociala ställning, ålder och civilstånd? I dennThis dissertation deals with the social structure of ordinary life in an early modern Swedish town as seen from the perspective of women. The questions which are dealt with are: What kinds of social relations, in addition to those inside the family, were women in an early modern town involved in? How did these differ from the relations men were involved in and how did they differ with regards to t
