Severe cerebral intraventricular hemorrhage (IVH) in preterm infants continues to be a major clinical problem, occurring in about 15-20% of very preterm infants. In contrast to other brain lesions the incidence of IVH has not been reduced over the last decade, but actually slightly increased. Currently over 50% of surviving infants develop post-hemorrhagic ventricular dilatation and about 35% deve

The kinetics and mechanism of the reactions between trans-[PtI3(PPh3)]– and trans-[PtI3(SbPh3)]– with pyridine, 2- and 4-methylpyridine in acetonitrile solvent have been studied by stopped-flow spectrophotometry. The crystal and molecular structures of the tetrabutylammonium salts of the two anions have been determined. Substitution of iodide trans to stibine is reversible and takes place via paraThe kinetics and mechanism of the reactions between trans-[PtI3(PPh3)]– and trans-[PtI3(SbPh3)]– with pyridine, 2- and 4-methylpyridine in acetonitrile solvent have been studied by stopped-flow spectrophotometry.

Context. High resolution stellar spectral atlases are valuable resources to astronomy. They are rare in the 1-5 μm region for historical reasons, but once available, high resolution atlases in this part of the spectrum will aid the study of a wide range of astrophysical phenomena. Aims. The aim of the CRIRES-POP project is to produce a high resolution near-infrared spectral library of stars across

Whilst many studies have been performed to investigate the spectral induced polarization (SIP) response of Non-aqueous Phase Liquid (NAPL) contaminated soil samples there are still many uncertainties in the interpretation of the data. A key issue is that altered pore space geometries due to the presence of a NAPL phase will change the measured IP spectra. However, without any information on the NA

This chapter provides a high-level summary of the state of knowledge regarding observations, processes and models of climate, terrestrial ecosystems and the global carbon cycle. We focus strongly on observations (at various timescales, including palaeo timescales as appropriate), and what can be learned from their interpretation in the light of the established principles of climate science and ter

Aims: The roles of the diverse populations of micro-organisms responsible for biodegradation of organic matter to form methane and carbon dioxide are rudimentarily understood. To expand the knowledge on links between microbial communities and the rate limiting, hydrolytic stage of two-stage biogas production from energy crops, this study was performed. Methods and Results: The process performance.

The aim of the present study was to investigate seasonal and spatial patterns of soil oxygen consumption, nitrification, denitrification and fluxes of dissolved inorganic nitrogen (DIN) in a tidal salt marsh of the Lagoon of Venice, Italy. In the salt marsh, intact soil cores including overlying water were collected monthly at high tide from April to October in salt marsh creeks and in areas cover

Popular Abstract in Swedish Denna avhandling undersöker hur vi använder visuell kontextinformation i samtal. Alla modeller över språkprocessning och kommunikation är ense om att visuell kontextinformation har en positiv nettoeffekt på förståelse och kommunikation. Trots detta är det inte klart genom vilka mekanismer denna kontextinformation verkar, eller om dessa mekanismer fungerar i situationer This dissertation is about the role of visual context information in communication. All accounts of language processing and communication agree that visual context is beneficial for understanding. Despite this, it is not clear through which mechanisms visual context works and whether these mechanisms also work in communication outside the lab setting. This dissertation aims to provide answers to t

Popular Abstract in Swedish Konventionella neuropsykologiska test, och begåvningstest, tar sällan hänsyn till att begåvningen "filtreras" genom individens personlighet vid utförandet av uppgifterna. Två lika begåvade personer (dvs med samma IQ) kan utföra samma test på helt olika sätt beroende på t.ex att den ena är impulsiv och snabb och den andra eftertänksam och försiktig. Detta medför skillnad"Personality determines very largely the use a person makes of his intellectual gifts" (Eysenck, 1988). Computerization of neuropsychological tests has made possible a detailed analysis of both quantitative and qualitative aspects of a person´s test performance. Factor analyses of test data generally bring out two main factors of performance: speed and accuracy, representing both the intellectual

Families living with a person with mental illness can experience distress requiring therapeutic interventions. Web-based mindfulness interventions have shown beneficial health outcomes for both clinical and healthy populations, and may help families cope and overcome barriers that can otherwise hinder a help-seeking process. Aims: To develop and assess outcomes of a web-based mindfulness intervent

Background: S100A9 has been shown to be important for the function of so called Myeloid Derived Suppressor Cells (MDSC). Cells with a similar phenotype are also involved in pro-inflammatory processes, and we therefore wanted to investigate the gene expression and function of these cells in animals that were either subjected to chronic inflammation, or inoculated with tumors. Methods: CD11b(+)Ly6C(

The Swedish Antarctic Research Expedition named “SWEDARP” was performed during October 1988 through April 1989. The aim of our project was to study the radioactivity in air and water from Gothenburg to the Antarctic. Between Gothenburg and the Equator, the average activity concentration of 7Be in air was 4.3 ± 0.7 mBq/m3. The activity concentration of 7Be in the South Atlantic down to Antarctica v

A 3D model is developed to describe an anode-supported planar solid oxide fuel cell (SOFC), by ANSYS/Fluent evaluating reactions including methane steam reforming (MSR)/water-gas shift (WGSR) reactions in thick anode layer and H-2-O-2/CO-O-2 electrochemical reactions in anode active layer, coupled with heat, mass species, momentum, and ion/electron charges transport processes in SOFC. The predicte

Amyloid deposits from several human diseases have been found to contain membrane lipids. Co-aggregation of lipids and amyloid proteins in amyloid aggregates, and the related extraction of lipids from cellular membranes, can influence structure and function in both the membrane and the formed amyloid deposit. Co-aggregation can therefore have important implications for the pathological consequences

Popular Abstract in Swedish Antalet personer som är amputerade ovanför tålederna i Sverige kan uppskattas till mellan 5000 och 5500. (ca 0.06 % av befolkningen). Största delen av dessa är amputerade pg.a. av kärlsjukdom (≈ 80 %). Antalet årligen nytillkomna benamputerade i Sverige kan uppskattas till mellan 1000-1100 och mindre än 5 % av dessa fall är relaterade till andra orsaker, t.ex. trauma elThe current prevalence of persons amputated at transmetatarsal level or higher in Sweden can be estimated to be between 5000 and 5500 persons (approx. 0.06 % of the population). The majority of these are patients with vascular disease (≈ 80%). In Sweden between 1000 and1100 new amputees can be expect every year. Less than 5% of all amputations will be related to causes other than vascular disease.

The thesis discusses closed-loop control of the hypnotic and the analgesic components of anesthesia. The objective of the work has been to develop a system which independently controls the intravenous infusion rates of the hypnotic drug propofol and analgesic drug remifentanil. The system is designed to track a reference hypnotic depth level, while maintaining adequate analgesia. This is complicat

I delar av Danmarks (Sjælland) grundvatten har det hittats nickel- och arsenikhalter över gränsvärdena bestämda av World Health Organization (WHO). Där har mineralet pyrit undersökts och visat sig innehålla dessa ämnen. Förhöjda halter av arsenik har även upptäckts i skånskt grundvatten av Sveriges geologiska undersökning (SGU). Kalkberggrunden i Danmark och Sverige, som har bildats på liknande säThe groundwater in parts of Danmark (Sjælland) is known to exceed the World Health Organizations limits for arsenic and nickel contents in drinking water according to the Danish Geological Survey (Flindt Jörgensen, 2005a; Flindt Jörgensen, 2005b; Stockmarr 2005). In groundwater in Scania the Swedish Geological Survey has found exceeding contents of arsenic. Therefore, this study investigated pyrit

Sri Lanka has been a leading example among developing nations in the fight against poverty. Human development has been a priority of the Sri Lankan government, and many social indicators are today more in line with those of a developed country. Still poverty is a severe and widespread problem in the country. The economic growth has been under the country’s potential, and the unequal development ha
