Heterogena katalysatorer för användning i bränslecellssystem har undersökts baserat på aktiv fas och tillverkningsmetoder för granulat- och monolitkatalysatorer. Katalysatorerna tillverkades genom att använda θ – aluminiumoxid som bärare, dopad med lantan och cerium, där den aktiva fasen bestod av ädelmetall X och nickel i varierande halter. Analys gjordes genom att låta en blandning av vattenångaHeterogeneous catalysts to be used in a pre-reformer for fuel cell systems have been investigated based on active phase composition and catalyst preparation methods for granulate and monolithic catalysts. The catalysts were manufactured using θ – aluminum oxide as carrier, promoted with lanthanum and cerium, with active phases consisting of noble metal X and nickel in various concentrations. Analy

Populariteten för släktforskning har vuxit under dom senaste åren. Detta beror framför allt på att det blivit avsevärt enklare genom internets framfart. Idag kan privat personer bedriva släktforskning hemifrån då man tidigare behövde hjälp från arkivister och professionella släktforskare. Då stora mängder släktdata har digitaliserats och lagts ut på nätet genom olika internationella företag och idAssociation for computer aided genealogy research of Sweden(DIS) is investigating the possibility of a nationwide genealogical database (RGD) of Sweden's historical population. The finished database should contain basic information about individuals' names, birth, marriage, death, and individuals' relationships such as father, mother, husband/wife and children. This will make up a kind

Den 1 oktober 2009 trädde en de nya Takeover-reglerna i kraft. Den största nyheten i de nya reglerna var den kraftigt minskade möjligheten att erbjuda röststarka aktier ett högre pris än röstsvaga aktier i ett offentligt uppköpserbjudande. Detta är en skärpning av den aktiemarknadsrättsliga likhetsprincipen och avsikten var att tillförsäkra minoritetsägare en större del av uppköpspremien. UppsatseThe 1 October 2009 new Takeover Rules entered into force. The most material change of the new rules was that they decreased the possibility to offer multiple voting shares a higher price than ordinary shares. This is a strengthening of the legal principle of equality as applied at the Nasdaq OMX Stockholm stock market. The intention was to ensure that minority shareholders got a greater share of t

Abstract Estuaries and salt marshes are important wetlands used by waterbirds during winter and migration. However, many salt-marshes have been transformed into salinas, which currently function as high-tide roosts. Since traditional salt production is no longer profitable, many salinas have been abandoned or converted into aquaculture potentially becoming less attractive to waders. In this study

Purpose: To investigate the possibility to be able to offer left sided breast cancer patients, not suitable for DIBH, an organ at risk saving treatment. Materials and Methods: Twenty patients receiving radiotherapy for left breast cancer in DIBH were enrolled in the study. Planning CT scans were acquired in the same supine treatment position in FB and DIBH. 3DCRT_DIBH plans were designed and optim

BACKGROUND: Metformin use has been associated with improved survival in patients with different types of cancer, but research regarding the effect of metformin on cutaneous melanoma (CM) survival is sparse and inconclusive.OBJECTIVES: To investigate the association between metformin use and survival among patients with CM and diabetes.METHODS: All adult patients with a primary invasive CM between

The overall aim of this paper is to introduce a new way of analysing and understanding the framing and potential of Physical Education and Health (PEH) practice. Focusing on subject-specific literacy, which is defined as an abstract and generalising language, containing words and concepts typical for a specific subject [Nestlog, B. E. (2019).

Background: Few data have looked at the occurrence and clinical correlates of self-reported shorter than desired ejaculation latency (rapid ejaculation, RE) and its related distress in the general population. Aim: To determine the prevalence and clinical correlates of self-reported RE and RE- related distress in middle age and older European men. Methods: Subjects were recruited from population sa

Increasing water deficits and severe droughts are expected to alter the dynamics of vegetation post-disturbance recovery by decreasing new recruitment and limiting growth in semi-arid Mediterranean ecosystems in future. However, which vegetation metrics will be shifted and how they respond over time are not clear, and the experimental evidence is still limited. Here we assessed the impacts of a lo

INTRODUCTION: The aim was to investigate psychiatric health care utilization two years before death by suicide among individuals with previous suicide attempts (PSA) compared with those without (NSA).METHOD: A retrospective population-based cohort study was conducted including 484 individuals who died by suicide in Sweden in 2015 and were in contact with psychiatric services within the two years p

Land-use changes, pollution and climate warming during the 20th century havecaused changes in biodiversity across the world. However, in many cases, the environmental drivers are poorly understood. To identify and rank the drivers currentlycausing broad-scale floristic changes in N Europe, we analysed data from two vascularplant surveys of 200 randomly selected 2.5 9 2.5 km grid-squares in Scania,

BACKGROUND: Thirty-eight years of pediatric heart transplantation (pHTx) within the Scandiatransplant organization were analyzed to describe volume trends, regional prevalence, underlying etiologies and outcomes following listing and pHTx.METHODS: Children <18 years listed for pHTx from January 1st 1986 to December 31st 2023 were identified in the Scandiatransplant registry. The cohort was split i

Additionally, we compared the consumption of various food groups in relation to iron status.METHODS: Data were collected from 475 female high school students in Malmö and Lund, Sweden, using questionnaires on di

AIM: Factors associated with unexpected absence or presence of coronary atherosclerosis in individuals at high/low estimated cardiovascular (CV) risk are largely unexplored. We assessed two extreme phenotypes: 1) no coronary atherosclerosis despite very high CV risk; and 2) severe-extensive coronary atherosclerosis despite low CV risk.METHODS: A multicenter, cross-sectional nationwide, population-

Context. The second release of Gaia data (Gaia DR2) contains the astrometric parameters for more than half a million quasars. This set defines a kinematically non-rotating reference frame in the optical domain. A subset of these quasars have accurate VLBI positions that allow the axes of the reference frame to be aligned with the International Celestial Reference System (ICRF) radio frame. Aims. W

For historical reasons, Swedish railways use 15 kV/16? Hz overhead contact lines for train traction, while the most common standard worldwide is 25 kV/50-60 Hz. This leads to higher investment costs for railway conversions and expansions, and to greater energy losses in the distribution of electricity to the trains. Yet to get away from these drawbacks by investing in a 25 kV/50 Hz overhead contac
