In recent years the use of repetition rate multiplication (RRM) on direct geometry neutron spectrometers has been established and is the common mode of operation on a growing number of instruments. However, the chopper configurations are not ideally optimised for RRM with a resultant 100 fold flux difference across a broad wavelength band. This paper presents chopper configurations that will produ
Introduction. In recent years, there has been a growing interest in ethnographic research within the field of library and Information studies. Although ethnography has been used by information researchers for studying a wide variety of phenomena, discussions concerning methodological developments and directions, as well as ethnography’s wider applicability within the field are rare. Our intent is
A new method for calibrating the hadron response of a segmented calorimeter is developed and successfully applied to beam test data. It is based on a principal component analysis of energy deposits in the calorimeter layers, exploiting longitudinal shower development information to improve the measured energy resolution. Corrections for invisible hadronic energy and energy lost in dead material in
Background: Plasmodium falciparum transmission has decreased significantly in Zambia in the last decade. The malaria transmission is influenced by environmental variables. Incorporation of environmental variables in models of malaria transmission likely improves model fit and predicts probable trends in malaria disease. This work is based on the hypothesis that remotely-sensed environmental factor
Background: Caldicellulosiruptor species have gained a reputation as being among the best microorganisms to produce hydrogen (H2) due to possession of a combination of appropriate features. However, due to their low volumetric H2 productivities (QH2), Caldicellulosiruptor species cannot be considered for any viable biohydrogen production process yet. In this study, we evaluate biofilm forming pote
Popular Abstract in Swedish Huntingtons sjukdom (HS) är en ärftlig hjärnsjukdom utan botemedel. Den orsakas av en mutation i en gen som kallas huntingtin. Den klassas som en s.k. neurodegenerativ sjukdom, där man ser en förlust av neuroner i delar av hjärnan som kontrollerar kroppsrörelser. Detta resulterar i dansliknande rörelser (chorea) och det är även därför som HS ibland kallas för danssjukanHuntington’s disease (HD) is a fatal, hereditary disease for which there is no cure. It is caused by a mutation in a gene called huntingtin. HD is a so-called neurodegenerative disease, where there is a loss of neurons in areas of the brain that control body movements. This results in uncontrolled dance-like movements (chorea). Traditionally, research on HD has focused round the brain and what is
Patients waiting for heart transplantation due to a failing heart can get a left ventricular assist device (LVAD) implanted through open chest surgery. The device consists of a pump that pumps blood from the left ventricle into the aorta. To get the correct rotation speed of the pump, the physicians consider a number of measurements as well as a sequence of echocardiographic images. The important

Background and Objective: Epilepsy is one of the most common neurological disorders, affecting more than 3 million people in Europe. This paper reviews the published evidence regarding the cost effectiveness of second-generation antiepileptic drugs (AEDs). Methods: A systematic literature search was performed, using the databases Academic Search Complete, Econlit, EMBASE and MEDLINE. Health econom
Abstract in Undetermined This study used passive telemetry (passive integrated transponders) to evaluate winter migration in three species of cyprinids (roach (Rutilus rutilus (L.)), white bream (Blicca bjoerkna (L.)) and rudd (Scardinius erythrophthalmus (L.))) and their potential predators (pike (Esox lucius (L.)) and perch (Perca fluviatilis (L.))) between a shallow lake and its streams. Migrat
Low grade systemic inflammation (LGSI) as well as androgen deficiency has in older men been associated with several pathologies, including cardiovascular disease (CVD). We wanted to investigate whether low testosterone levels are linked to biomarkers of LGSI already in young age, before any concurrent manifestations of CVD or other systemic diseases.
The review asks how the adaptive filter model of the cerebellum might be relevant to experimental work on zone C3, one of the most extensively studied regions of cerebellar cortex. As far as features of the cerebellar microcircuit are concerned, the model appears to fit very well with electrophysiological discoveries concerning the importance of molecular layer interneurons and their plasticity, t
TASISpec (TASCA in Small Image mode Spectroscopy) combines composite Ge- and Si-detectors for a new detector setup aimed towards multi-coincidence gamma -ray, X-ray, conversion electron, fission fragment, and a-particle spectroscopy of the heaviest nuclei. It exploits the TASCA separator's unique small image focal mode, i.e. the fact that evaporation residues produced in fusion-evaporation reactio
Skin fibrosis is characterized by activated fibroblasts and an altered architecture of the extracellular matrix. Excessive deposition of extracellular matrix proteins and altered cytokine levels in the dermal collagen matrix are common to several pathological situations such as localized scleroderma and systemic sclerosis, keloids, dermatosclerosis associated with venous ulcers and the fibroprolif
Within both psycholinguistic theories of parsing and formal theories of syntax, a distinction between arguments and adjuncts is central to some theories, while minimized or denied by others. Even for theories that deem the argument/ adjunct distinction important, the exact nature of the distinction has been difficult to characterize. In this article, we review the psycholinguistic evidence for an
Background: The presence of enthesitis (insertional inflammation) in patients with juvenile idiopathic arthritis (JIA) is difficult to establish clinically and may influence classification and treatment of the disease. We used ultrasonography (US) and color Doppler (CD) imaging to detect enthesitis at the small and deep-seated proximal insertion of the gluteus medius fascia on the posterior iliac
Summary In the majority of the field studies reviewed in this report samples were exposed outdoors above ground and only the average moisture content was determined. Therefore, no information is given about the moisture content in joints and other moisture traps. In many of the field studies, information on relative humidity, temperature, rainfalls etc. is missing and consequently these field stud
The primary topic of this thesis is a class of tempo-spatial models which are rather flexible in a distributional sense. They prove quite successful in modeling (temporal) dependence structures and go beyond the limitation of Gaussian models, thus allowing for heavy tails and skewness. By generalizing the construction of the above class of models, it is possible to ‘control’ some random geometric
