We characterize attosecond pulses in a train using both the well established "reconstruction of attosecond beating by interference of two-photon transitions" (RABITT) technique and the recently demonstrated in situ method, which is based on a weak perturbation of the harmonic generation process by the second harmonic of the laser field. The latter technique determines the characteristics of the si
This article is based upon "The management of diabetic foot osteomyelitis - a progress report on diagnosing and a consensus on treating osteomyelitis". The principle of treatment is to administer antibiotics while providing a local environment in which the medication can work. This typically involves the removal of dead, soft tissue and accessible dead bone during the wound care process. These int
We have investigated the possibility of using carbon nanotubes as flexible, mobile electrical probes able to electrically contact nanometre- scaled objects. Configurations with metal electrodes evaporated on top of multi-, few- and single-wall carbon nanotubes have been studied. Scanning probe manipulation was used to create nano-mechanical switches by first cutting the various tubes, and then mov
This article argues that the body of foreign direct investment (FDI) literature in general and the ownership, location, and internalization (OLI) paradigm in particular would be enriched if finance-specific factors are explicitly incorporated as drivers of FDI. We suggest that financial strategies involving factors such as debt/equity swaps or equity listings in foreign equity markets affect the f
Protein C inhibitor (PCI) is a heparin-binding serine proteinase inhibitor belonging to the family of serpin proteins. Here we describe that PCI exerts broad antimicrobial activity against bacterial pathogens. This ability is mediated by the interaction of PCI with lipid membranes, which subsequently leads to their permeabilization. As shown by negative staining electron microscopy, treatment of E
The evaporative gas turbine (EvGT), also known as the humid air turbine (HAT) cycle, is a novel advanced gas turbine cycle that has attracted considerable interest for the last decade. This high-efficiency cycle shows the potential to be competitive with Diesel engines or combined cycles in small and intermediate scale plants for power production and/or cogeneration. A 0.6 MW natural gas-fired EvG
This paper investigates how vascular plants affect carbon flow and the formation and emission of the greenhouse gas methane (CH4 ) in an arctic wet tundra ecosystem in NE Greenland. We present a field experiment where we studied, in particular, how species-specific root exudation patterns affect the availability of acetate, a hypothesized precursor of CH4 formation. We found significantly higher a
BACKGROUND: To investigate, in a rabbit model, the effect of two different doses of vigabatrin (VGB) on retinal function and morphology. METHODS: Twenty-nine rabbits of mixed strain were divided into two groups, receiving either high-dose (n = 15) or low-dose (n = 14) oral VGB treatment (cumulative dose 29.8 +/- 2.9 g and 14.2 +/- 0.6 g respectively). Ten rabbits receiving water served as control
Two mobile agents having distinct identifiers and located in nodes of an unknown anonymous connected graph, have to meet at some node of the graph. We present fast deterministic algorithms for this rendezvous problem.
The authors examined the hypothesized association between the body burden of polychlorinated biphenyls (PCB) in women and the risk of low birth weight for their infants. In Sweden, a main exposure route for PCBs and other persistent organochlorine compounds is through the consumption of fatty fish from the Baltic Sea (on the Swedish east coast). A previous comparison between a cohort of consumers
Objective— The reasons for the relationship between inflammation-sensitive plasma proteins (ISPs) and incidence of cardiovascular diseases are poorly understood. This study explored the hypothesis that ISPs are associated with future hypertension and age-related blood pressure increase. Method and Results— Blood pressure and plasma levels of fibrinogen, {alpha}1-antitrypsin, haptoglobin, cerulopl
The problem of reconstructing two-dimensional vector fields from tomographic measurements based on Doppler techniques is addressed. Measurements are made along lines, from which distributions of the field component parallel to the line are obtained. A new transform, the Doppler moment transform, which extracts local information from such data, is introduced. In contrast to most previous approaches
Although N- and P-type Ca2+ channels predominant in fast-secreting systems, Lc-type Ca2+ channels (C-class) can play a similar role in certain secretory cells and synapses. For example, in retinal bipolar cells, Ca2+ entry through the Lc channels triggers ultrafast exocytosis, and in pancreatic beta-cells, evoked secretion is highly sensitive to Ca2+. These findings suggest that a rapidly release
SummaryThe expansion of the European Union during the last 2 yr has resulted in the need for a revision of existing guidelines to further harmonize education and training in the specialty of anaesthesiology throughout the European Union. Although each individual country is responsible for its own training and certification, these guidelines are intended to reflect minimum criteria for specialist t
We sought to evaluate the experiences and knowledge of health care providers in Sweden regarding female genital cutting (FGC) as a health issue. Questionnaires (n = 2,707) were sent to providers in four major cities in Sweden and evaluated by means of descriptive statistics. Twenty-eight percent (n = 769/2,707) responded, of whom 60% had seen such patients. Seven providers, including 2 pediatricia
The aim of this study was to describe young (under the age of 7) children’s needs as expressed by their behavior, body language and verbal expression through observations during their initial hospitalization after being diagnosed with cancer. Twelve children under the age of seven were followed during 26 hours with nonparticipant unstructured observations. Field notes were written after each obser
