Ocean waves exhibit more or less a Gaussian distribution for the instantaneous water surface height, and there is a need to develop simple models for generation of the characteristic non-Gaussian statistics, namely the asymmetric distributions of water surface height and wave slope. We argue that a simple class of non-linear oscillators can reproduce some of the characteristic features of random w

IntroductionBeta-lactam antibiotics are essential in the treatment of Gram-negative bloodstream infections. The effect of beta-lactam antibiotics depends on the time of unbound antibiotic concentration above the minimal inhibitory concentration (MIC). An antibiotic concentration above MIC during the whole dosing interval (100% ƒT > MIC) has been suggested as a target for severe infections. The aim
“The implications and applications of biotechnology continue to be at the centre of public debate. In the light of rapid scientific advances and novel insights, the multi-faceted discussions are particularly fierce with regard to patents on DNA–related technology. In the often very emotionally-led debate basically two directly conflicting schools of thoughts can be identified. Some people believe

In this paper, we propose a new system-level design language, called SystemJ. It extends Java with synchronous reactive features present in Esterel and asynchronous constructs suitable for modelling globally asynchronous locally synchronous systems. The strength of SystemJ comes from its ability to offer the data processing and encapsulation elegance of Java, Esterel-like reactivity and synchrony,
Popular Abstract in Swedish Gastroesofageal refluxsjukdom innebär att maginnehåll backar (reflux) upp från magsäcken till matstrupen på ett onormalt sätt. Hos den friska individen finns flera mekanismer som skyddar matstrupen från reflux, vilket tydligt åskådliggörs av att man efter en måltid kan ställa sig upp och ner utan att föda backar upp i matstrupen. Vid refluxsjukdom föreligger defekter inEsophageal pH monitoring is important in the clinical management of patients with symptoms suggestive of gastroesophageal reflux disease (GERD), and in research aiming to clarify the mechanisms involved in the development of GERD complications. Catheter-based techniques for pH recording are uncomfortable, not well tolerated by all patients and cannot reliably measure acid exposure in the most dist
This doctoral dissertation presents the development and digital hardware realization of cardiac event detectors. Implantable medical appliances, as the cardiac pacemaker, have progressed from a life sustaining device to a device that considerably improves life quality for all ages. The number of electronic devices and household appliances in everyday live has an ongoing exponential growth. The
An experimental study was performed to investigate the dependency of particle size on the deposition rate. Polystyrene latex particles of two radii (0.23 and 0.38 mum) were deposited onto a glass surface covered with indium-tin oxide. Reduced deposition efficiency was observed for the larger particles, although an increase in the deposition efficiency was seen as that the diffusion boundary layer
That data from polar orbiting satellites have detected a widespread increase in photosynthetic activity over the last 20 years in the grasslands of the Sahel is justifies investigating its role in the tropical carbon cycle. But this task is undermined because ground data that are generally used to support the use of primary production models elsewhere are lacking. In this paper, we profile a Light
The aim of this study was to explore older patients' experiences of participation in the prescription process of mobility devices. The study was conducted in two Swedish municipalities and was a qualitative study, based on the focus group interview methodology of Merton et al (1990). In order to recruit a sample fulfilling both homogeneity and heterogeneity criteria, occupational therapists and p
Two different mathematical methods of implementing a detailed kinetic soot model have been employed in this work. The theoretical description of the soot modeling employed in this work is divided into three parts. Initially a detailed kinetic soot model is described from a chemistry and physics perspective. The soot model is then elaborated into mathematical form, starting with the formulation of
In this study a modified mid-ranging strategy is proposed where the controller for the secondary manipulated variable uses its own output as its setpoint, possibly with an offset and/or re-scaling. This modification allows the manipulated variables to increase in unison so that the mid-ranging advantage of utilizing the fast dynamics of the primary controller to regulate the process can be achieve
This paper presents an analysis of a regional transport infrastructure plan in Sweden. A comparison is made of two concepts central to transport infrastructure planning in Sweden; Regional expansion and Environmentally sound transport. These concepts signify different perspectives on the benefits and problems with transport. The analysis explains how these clashing perspectives are resolved in the
A large part of the literature published in the ‘Global South’ is barely covered by bibliographic databases. Institutional policies increasingly require researchers globally to publish in ‘international’ journals, draining local infrastructures. The standard-setting power of ‘Global South’ scholars is minimised further. My main aim is to render visible the ways in which European academic libraries
Within the paradigm of population dynamics a central task is to identify environmental factors affecting population change and to estimate the strength of these effects. We here investigate the impact of observation errors in measurements of population densities on estimates of environmental effects. Adding observation errors may change the autocorrelation of a population time series with potentia
In fragmented landscapes, mobility is an important trait for population persistence but the predictions on the relationship between habitat fragmentation and extinction risk are contradictory. Here, we test the effects of the two main aspects of fragmentation, patch area and isolation, on the species richness of groups of butterflies associated with semi-natural grasslands, differing in mobility.
