Selective isomerization of 1-alkenes by binary metal carbonyl compounds

An efficient and selective isomerization of 1-alkenes to their corresponding 2-alkenes is achieved by using binary metal carbonyls such as Ru-3(CO)(12) as catalysts. Possible mechanisms are discussed. Substituents on the 1-alkene have a significant effect on the isomerization. (C) 2008 Elsevier Ltd. All rights reserved.

Novel Aspects of the Coagulation System in Host Defence

Bacterial infections are a major global threat to public health and sepsis is a major cause of morbidity and mortality. Sepsis incidence is rising, with supportive treatments and antibiotics being the main treatment possibilities. Sepsis is characterised by an excessive and uncontrolled immune and coagulation response, leading to tissue damage, capillary leakage, and multiple organ failure. Althou

Spring photosynthetic recovery of boreal Norway spruce under conditions of elevated [CO2] and air temperature

Accumulated carbon uptake, apparent quantum yield (AQY) and light-saturated net CO2 assimilation (A(sat)) were used to assess the responses of photosynthesis to environmental conditions during spring for three consecutive years. Whole-tree chambers were used to expose 40-year-old field-grown Norway spruce trees in northern Sweden to an elevated atmospheric CO2 concentration, [CO2], of 700 mu mol C

Doing the Right Things or Doing Things Right? : Paradoxes and Swedish Communication Professionals’ Roles and Challenges

Purpose – The purpose of this paper is to examine and analyze the prevailing form of rationality that governs the challenges, goals and roles of communication professionals. The authors will also explore alternative forms of rationality and discuss what these would imply. Design/methodology/approach – The paper is based on survey results from The European Communication Monitor (ECM) and qualitativ

Large-scale Feature Evolution: Problems and Solutions from the Mobile Domain

Abstract in UndeterminedYou may think that your requirements engineering process is fairly limited and currently not too complex to manage. Or you may be right in the middle of a storm of requirements where it is impossible to manage even the most important ones comprehensively. If you are in the former situation, it may be dangerous to relax as many successful software-intensive products have a t

Modern, svensk och jämställd. Om barn, familj och omvärld i grundskolans läseböcker 1962-2007

Abstract The aim of the thesis has been to explore representations of gender, ethnicity and generation in school readers used in the Swedish compulsory school since 1962, to find which ’discourses’, linked to equal opportunities, integration/diversity and childhood, underlie these constructions, and in which ways they may have contributed to the (re)production of different gendered, ethnified and

An alternative way of estimating asset values and asset value correlations

Abstract in UndeterminedWe suggest a new way of modeling the dynamics of a firm’s asset value and discuss how it could be useful in the computation of asset value correlations in multivariate credit risk models. The method relies on credit spreads from the credit default swap market and by combining these spreads with stock prices and leverage ratios we show how one can construct a proxy for the a

Effects of brown and turbid water on piscivore-prey fish interactions along a visibility gradient

1. Environmental changes such as eutrophication and increasing inputs of humic matter (brownification) may have strong effects on predatorprey interactions in lakes through a reduction in the visual conditions affecting foraging behaviour of visually oriented predators. 2. In this experiment, we studied the effects of visual range (25200 cm) in combination with optically deteriorating treatments (

Oral and sublingual immunotherapy for egg allergy

Background Clinical egg allergy is a common food allergy. Current management relies upon strict allergen avoidance. Oral immunotherapy (OIT) might be an optional treatment, through desensitization to egg allergen. Objectives We aimed to assess the successful desensitization and development of tolerance to egg protein and the safety of egg oral and sublingual immunotherapy in children and adults wi

Genome-wide association study identifies a new melanoma susceptibility locus at 1q21.3

We performed a genome-wide association study of melanoma in a discovery cohort of 2,168 Australian individuals with melanoma and 4,387 control individuals. In this discovery phase, we confirm several previously characterized melanoma-associated loci at MC1R, ASIP and MTAP-CDKN2A. We selected variants at nine loci for replication in three independent case-control studies (Europe: 2,804 subjects wit

Mobilizing for change: A study of research units in emerging scientific fields

Local research units. this article argues, play a very important role for the scientific field they belong to, for example by mobilizing financial support, offering job opportunities, attracting talented recruits, and providing adequate training. Little is known, however, about such units, at least in the fields under study here, i.e., studies of innovation, entrepreneurship and related phenomena.

Incretin Hormone Secretion - Studies in Human Subjects

Popular Abstract in Swedish Det finns ett flertal hormoner som bildas i mag-tarmkanalen och som sedan frisätts till blodet i samband med måltidsintag. Runtom i kroppen finns det sedan målceller, så kallade receptorer, som stimuleras av hormonerna till att påverka olika processer i kroppen. De hormoner från mag-tarmkanalen som vi har studerat är de så kallade inkretinhormonerna, glukagon-lik peptidSeveral different hormones are released from the intestine following a meal. In this thesis we have focused on the so called incretin hormones, glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). An important function of the incretin hormones is potentiation of insulin release from pancreatic beta-cells following a meal. This property has attracted a lot of inte

Treatment response to a second or third TNF-inhibitor in RA: results from the South Swedish Arthritis Treatment Group Register.

Objectives. To study treatment response rates of RA patients undergoing second- and third-line anti-TNF therapy and to identify baseline predictors of response to second-line treatment. Methods. RA patients monitored in a prospective, observational study, having switched anti-TNF therapy once (first-time switchers, n = 337) or twice (second-time switchers, n = 36)-i.e. following failures with one

Hearing loss and a supportive tactile signal in a navigation system: Effects on driving behavior and eye movements

An on-road study was conducted to evaluate a complementary tactile navigation signal on driving behaviour and eye movements for drivers with hearing loss (HL) compared to drivers with normal hearing (NH). 32 participants (16 HL and 16 NH) performed two preprogrammed navigation tasks. In one, participants received only visual information, while the other also included a vibration in the seat to gui

Etnicitet i ungdomsvården. Yrkesverksammas och ungdomarnas muntliga framställningar

I denna studie analyseras muntliga etnicitetsgestaltningar hos olika aktörer i ungdomsvården. Undersökningen uppmärksammar etniciteten när den uttrycks verbalt och icke-verbalt, hur den uttrycks samt i vilka situationer kategoriseringar synliggörs implicit eller explicit. Studiens syfte är: att analysera när och hur etnicitet aktualiseras genom kategoriseringar i ungdomsvården, att uppmärksamma hThe aim of this study is to analyze when and how ethnicity is actualised through categorisations in Swedish youth-care, to attract attention to how these categorisations are indicated and point out how the narrators own ethnic identity is shaped and upheld through different markings. The report is based on 109 interviews conducted with different actors in the youth-care and my field-notes made in

Feeding the Needy Student: Auto-Ethnographic Reflections from South India

Towns and cities have always been sites of attraction not only as centers of trade and commerce, seats of administration and power centers but also providing facilities for health and education. This is especially true of post-colonial nations such as India, marking differences between rural and urban areas in many significant ways. The late colonial and early post-colonial periods experienced wid
