purpose of this study was to elaborate a model for estimating the caries-reducing effect of a preventive measure with due consideration of background factors. The material comprised 50 children, who had consumed NaF tablets regularly during preschool age, and 76 comparable children who had never consumed NaF tablets. They were all examined at 12 and 13 yr of age. Information on caries and, as conf
This paper introduces a new substrate for reverse-phase protein microarray applications based on macroporous silicon. A key feature of the microarray substrate is the vastly surface enlarging properties of the porous silicon, which simultaneously offers highly confined microarray spots. The proof of principle of the reverse array concept was demonstrated in the detection of different levels of cyc
The paper compares two lexical items, Icelandic ma@?ur and Swedish man, for the construction of a detached, general discourse stance (Berman, Ragnarsdottir and Stromqvist, 2002). Both forms mean 'man', but they can also be used in a generic sense. In that usage, Icelandic ma@?ur is associated with several semantic, pragmatic, and stylistic constraints, whereas Swedish man is more freely applicable
OBJECTIVE: In acute respiratory distress syndrome, the relationships between changes in the elastic behavior of the respiratory system and biological markers of extra-cellular matrix or surfactant turn-over could give some insights into its pathophysiological determinants. DESIGN AND MEASUREMENTS: In 17 patients with acute respiratory distress syndrome, we assessed the relationship between chord c
New palaeomagnetic results for the 935 Ma Goteborg-Slussen mafic dykes in southern Sweden provide a well-dated high-quality palaeomagnetic pole for Early Neoproterozoic Baltica. New U-Pb geochronological data for several palaeomagnetically studied mafic intrusions yield three additional well-dated palaeopoles and one virtual geomagnetic pole. This set of dated poles suggests minimal drift of Balti
The number of regulatory RNAs with identified non-canonical structures is increasing, and structural transitions often play a role in their biological function. This stimulates interest in internal motions of RNA, which can underlie structural transitions. Heteronuclear NMR relaxation measurements, which are commonly used to study internal motion, only report on local motions of few sites within t
One of the central tenets in life-history theory is that there is a trade-off between current and future reproduction (i.e. a cost of reproduction). The mechanism for this cost of reproduction is, however, largely unknown. One hypothesis is that the high workload during reproduction compromises resistance to parasites and that the resulting increase in parasitaemia has negative effects on the pros
Mass, heat and momentum transport processes are coupled with catalytic chemical reactions in a methane steam reforming duct. it is often found that endothermic and exothermic reactions in the ducts are strongly integrated by heat transfer from adjacent catalytic combustion ducts. In this paper, a three-dimensional calculation method is developed to simulate and analyze reforming reactions of metha
In many Voice over IP (VoIP) systems, the end-to-end voice Quality of Service (QoS) is largely dictated by the packet loss rate and the Packet Loss Concealment (PLC) method at the receiver. Typical PLC algorithms are usually based on simple signal extrapolation methods that can produce perceptually annoying artifacts. We present a taxonomy of PLC artifacts that degrade voice quality, and demonstra
The catalyst layer (CL) in polymer electrolyte membrane (PEM) fuel cells is one of the key components regulating the overall performance of the cell. In PEM fuel cells, there are two CLs having identical composition for hydrogen oxidation (HO) and oxygen reduction (OR) reactions. There are four phases inside the CL, namely: carbon, Pt particles, ionomer and voids. In this work, a micro-model of th
Methods for monitoring seepage and detecting internal erosion are essential for the safety evaluation of embankment dams. Internal erosion is one of the major reasons for embankment dam failures, and there are several tenths of thousands of large embankment dams in the world. Internal erosion is progressing inside the dam, and is sometimes difficult to detect by conventional methods. Therefore, th
Popular Abstract in Swedish Magnetresonanstomografi (MRT) är en metod för framställning av bilder av kroppen och av sjukliga förändringar i kroppen. När metoden introducerades ansågs den utomordentligt goda inbyggda vävnadskontrasten vara tillräcklig för att särskilja olika sjukliga förändringar, speciellt i hjärnan. Det har emellertid visat sig att förmågan att upptäcka sjukliga förändringar är oAims of the study The aims of this study using Gadodiamide injection were to investigate: · Whether Gadodiamide injection was comparable to Gd-DTPA for the enhancement of CNS lesions. · The contrast effect at different field strengths. · The effective time-window for the enhancement of blood-brain barrier damage. · The relations between the concentration of contrast agent and enhancement in p
