We study the probability distribution of the height of global maximum for a Gaussian random field evolving in time. Particularly, we discuss the role of the wave kinematics. It is observed that taking into account time dynamics of spatial characteristics results in distributions different from those obtained for the static case. We show how different characteristics of the sea surface like signifi
Abstract in UndeterminedThe questions dealt with in the course of this workshop are greatly complex. In order to outline the state of the art in Southern Scandinavia the character of the archaeological and palaeobotanical source material and different theories on early agriculture are summarized. Theoretical and methodological problems implied in ecological and archaeological interpretations of th
Several conditions for being an intrinsically intentional agent are put forward. On a first level of intentionality the agent has representations. Two kinds are described: cued and detached. An agent with both kinds is able to represent both what is prompted by the context and what is absent from it. An intermediate level of intentionality is achieved by having an inner world, that is, a coherent
Ingestion of aliphatic hydrocarbons--even in small amounts--can cause severe respiratory distress in children. Such accidents are becoming increasingly common in Sweden. A case of severe hydrocarbon ingestion is reported, where a 16-month-old boy, initially treated with mechanical ventilation for respiratory distress, subsequently developed a reversible radiological complication, pneumatocele. Pat

Purpose: To evaluate the functional disorders of the oral and pharyngeal phases of deglutition after repair of esophageal atresia in children. Material and Methods: 19 children (10 girls, 9 boys, mean age 22 months) underwent videofluoroscopy of deglutition after repair of esophageal atresia. The videofluoroscopic studies were assessed according to functional and morphological changes in the oral,
In this paper, two fundamentally different urban wastewater systems are assessed from an environmental impact perspective. One system represents a centralised, high-tech, end-of-pipe structure c whereas the second system is primarily based on source-separation strategies. Using material flow analysis a in combination with evaluation methods based on life-cycle assessment the systems are evaluated
Twelve palaeogeographical reconstructions illustrate environmental changes at the southwest rim of the Scandinavian Ice Sheet 40-15 kyr BP. Synchronised land, sea and glacier configurations are based on the lithostratigraphy of tills and intertill sediments. Dating is provided by optically stimulated luminescence and calibrated accelerator mass spectrometry radiocarbon. An interstadial sequence ca
The reduced bone mineral density (BMD) found in patients with fractures may, in part, follow rather than precede the fracture. We studied the magnitude and reversibility of bone loss in the 15 months following osteotomy in 21 men and 5 women with localized medial arthritis of the knee. BMD (mean +/- SD), measured using dual-energy X-ray absorptiometry, decreased by a maximum of 35 +/- 21% in the m
A general mass calibration procedure of a PIXE set-up is described. As an example, the results of the calibration of the PIXE set-up in Lund are given. For the calibration commercially available standards were used. The parameters of a physical model were adjusted to fit a calibration curve. To decrease errors due to inhomogeneities of the standard foils, the average from four different pieces of
We have applied the perforated patch whole-cell technique to beta cells within intact pancreatic islets to identify the current underlying the glucose-induced rhythmic firing of action potentials. Trains of depolarizations (to simulate glucose-induced electrical activity) resulted in the gradual (time constant: 2.3 s) development of a small (<0.8 nS) K(+) conductance. The current was dependent on
The recognition of microbes or microbial products by leukocytes is a key event in innate immunity. Binding of microbial products to cell surface receptors on phagocytes induce a response that includes the production of inflammatory mediators. One such mediator is the cytokine tumour necrosis factor alpha (TNF). TNF is a pleotropic cytokine with actions ranging from tissue injury to septic chock. T
Postoperative pain after total knee arthroplasty (TKA) is severe, and achieving adequate analgesia remains a clinical challenge. We tested the hypothesis that, in patients having unilateral TKA under intrathecal (IT) anesthesia, the addition of a femoral nerve block would provide superior analgesia when compared with IT morphine and demonstrate fewer adverse side effects. In a single-blinded and c
Ball rolling by dung beetles is considered to be a derived behaviour that evolved under pressure for space, and from competitors at the dung pat. Straight-line orientation away from the pat using a celestial cue should be the most successful rolling strategy to move dung to an unknown burial site. We tested this hypothesis in the field and the laboratory by presenting five species of ball-rolling
Runoff estimation is of high importance for many practical engineering applications so that, e.g. power production, dam safety and water supply can be ensured. The methods and time step relevant for runoff simulations vary depending on the location and the application. Long-term runoff simulation for Scandinavia is of high importance as its hydropower production is affected by climate variability,
