Much of the progress in astronomy follows imaging with improved resolution. In observing stars, current capabilities are only marginal in beginning to image the disks of a few, although many stars will appear as surface objects for baselines of hundreds of meters. Since atmospheric turbulence makes ground-based phase interferometry challenging for such long baselines, kilometric space telescope cl
The shielding at an accelerator-driven spallation neutron facility plays a critical role in the performance of the neutron scattering instruments, the overall safety, and the total cost of the facility. Accurate simulation of shielding components is thus key for the design of upcoming facilities, such as the European Spallation Source (ESS), currently in construction in Lund, Sweden. In this paper
Purpose of this paper The expression Enhanced Liability refers to clauses in a contract which obligation one of the partners to accept extended liability for future claims payments beyond normal standards of transport law, conventions or national standard terms and conditions for logistics service intermediaries, logistics service providers and carriers. This paper provides explanations and unders
Research in service management and marketing has in the past decade highlighted the concept of value creation. In service organizations value creation is described as a process in which the customer uses a company's value proposition in a meaningful way. However, research has tended to ignore the contextual meaning, and few empirical studies have shown how context is relevant. Therefore, the aim o
Many older people express strong preferences to remain in their own housing as long as possible. Due to declining health they may, however, become dependent on others for their daily care, eventually reaching a point where they consider relocation to a residential home. The overall aim of the dissertation is to reveal the process preceding older people’s potential relocation from ordinary housing
There is a great potential for phasor measurement applications in Scandinavia, mainly due to the long distance power transmission and limited transmission capacity expansion possibilities. Smart control, based on phasor measurements, can be used as an alternative to additional transmission lines, to increase power transmission capacity. Also the matter of damping is more and more becoming a key is
Objective: The aim of this article is to present the Swedish and Norwegian Testicular Cancer Group (SWENOTECA), with an emphasis on the history of SWENOTECA, organization, results and current status. Materials and methods: SWENOTECA was founded in 1981 as a binational organization open to hospitals in Sweden and Norway treating testicular cancer. It has since published treatment protocols for test
Pheromone-based mating disruption of the almond moth (Ephestia cautella) (Walk.) (Lepidoptera: Pyralidae) was carried out in a chocolate factory in Sweden. Population monitoring was conducted with pheromone-baited traps and water traps. Pheromone traps showed a 94% catch reduction, and monitoring with water traps showed a significant decrease in total catch (5.0 and 1.6 individuals per trap per we
The aim of the present study was to explore how a personal narrative told by a group of eight persons with aphasia differed between written and spoken language, and to compare this with findings from 10 participants in a reference group. The stories were analysed through holistic assessments made by 60 participants without experience of aphasia and through measurement of lexical and syntactic vari
Triple differential dijet cross sections in e(+/-)p interactions are presented in the region of photon virtualities 2 < Q(2) < 80 GeV2, inelasticities 0.1 < y < 0.85, jet transverse energies E*(T1) > 7GeV, E*(T2) > 5 GeV, and pseudorapidities - 2.5 < η(1)*, η(2)* < 0. The measurements are made in the gamma*p centre-of-mass frame, using an integrated luminosity of 57 pb(-1). The data are compared w
In this study a method for the analysis of simultaneous multiple measurements of kinematics and stabilizing forces related to human postural dynamics is proposed. Each subject in a group of normal subjects (n=10) was tested with eyes-open and eyes-closed with simultaneous but uncorrelated vestibular and proprioceptive stimuli in order to investigate the contributions of individual sensory feedback
Migratory land birds perform extreme endurance flights when crossing ecological barriers, such as deserts, oceans and ice-caps. When travelling over benign areas, birds are expected to migrate by shorter flight steps, since carrying the heavy fuel loads needed for long non-stop flights comes at considerable cost. Here, we show that great snipes Gallinago media made long and fast non-stop flights (
Background Glucocorticoid-mediated hypertension is incompletely understood. Recent studies have suggested the primary mechanism of this form of hypertension may be through the effects of glucocorticoids on vascular tissues and not to excess sodium and water re-absorption as traditionally believed. Objective The goal of this study was to better understand the role of the vasculature in the generati
Popular Abstract in Swedish Studier av enstaka makromolekyler gör det möjligt att få insikt i och karakterisera viktiga biologiska processer. DNA, livets molekyl, är av särskilt intresse här. I denna avhandling användar vi metoder från statistisk fysik för att studera olika aspekter av DNA i nanokanaler och dess smältegenskaper. DNA-smältning är inte bara relevant för förståelsen av denna molekylsInvestigation of single macromolecules makes it possible to gain insight into and characterize important biological processes. DNA as the molecule of life is of special interest here. In this thesis tools from statistical physics are used to study different aspects of DNA confined to nanochannels, with particular regard to its denaturation properties. The study of DNA melting from the theoretical
When a child has special communication needs, his or her entire family is affected. This position paper deals with “Xings” (crossings or just xings): active and reactive multisensory media, designed to be communicative on their own terms, challenging existing everyday communication patterns and augmenting family communication. The common shortcomings of oral and written language are no longer crit
New theoretical developments in impurity lattice dynamics are presented, with the emphasis on phonon broadening of core levels in metals. Detailed calculations have been made for Li and Na. The effects of non-linear screening are evaluated for the first time and are shown to increase the phonon broadening by about 70% for Li compared with the linear-screening value. The present a priori estimate o
Lignocellulose hydrolysate is an abundant substrate for bioethanol production. The ideal microorganism for such a fermentation process should combine rapid and efficient conversion of the available carbon sources to ethanol with high tolerance to ethanol and to inhibitory components in the hydrolysate. A particular biological problem are the pentoses, which are not naturally metabolized by the mai
Wind erosion causes severe damage on sandy soils in agricultural areas of north-west Europe. The weather conditions during erosion events are the result of the general atmospheric circulation and are key components in the erosion process. Principal component analysis (PCA) in combination with a non-hierarchical cluster analysis was conducted on de-seasonalized daily mean-sea-level pressure (MSLP)
