As multimedia- and group-oriented computing becomes increasingly popular for the users of wireless mobile networks, the importance of features like quality of service (QoS) and multicasting support grows. Ad hoc networks can provide users with the mobility they demand, if efficient QoS multicasting strategies are developed. The ad hoc QoS multicasting (AQM) protocol achieves multicasting efficienc
PURPOSE: To study factors that might contribute to intraoperative proximal type I endoleak and to evaluate the placement of giant Palmaz stents as a therapeutic option. METHODS: Thirty-three patients (30 men; median age 72 years, range 50-85) with abdominal aortic aneurysms underwent implantation of fully supported Gianturco Z-stent-based endografts (12 custom-made aortomonoiliac and 21 bifurcated
Customer orientation is strongly visible in the visions and strategies of most organizations, but how do these visions and strategies move from intentions to practice? This question provides the focus for this research which aims to acquire deeper insights into this process. The point of departure is the change in perspective from a product to a customer orientation in product and service developi
The relationship between on the one hand personality traits and, on the other hand, neuropsychological test performance, self-rated distress symptoms, psychosocial work exposure, and social interaction patterns, was studied in a group of healthy women (N= 101). All subjects completed the Karolinska Scales of Personality inventory (KSP) and the majority of the subjects (n = 88) completed the State
DIS data from HERA show a striking regularity as sigma(gamma*p) is a function of the ratio tau = Q(2)/Q(s)(2)(x) only. The scaling function shows a break at 7 t, which has been taken as an indication for saturation. However, besides saturation also the transition between dominance of k(perpendicular to)-ordered (DGLAP) and k(perpendicular to)-non-ordered (BFKL) evolution contributes to a break aro
A generic protocol for the creation of material-mediated self-assembled patterns of streptavidin, defined solely by patterns of gold and SiO2, is presented. Protein-adsorption resistance of selected regions was obtained by material-specific adsorption of thiol-modified poly(ethylene)glycol (thiol-PEG) on gold followed by adsorption of poly-L-lysine (PLL) modified PEG (PLL-g-PEG) on SiO2. Selective
The immunosuppressant drug cyclosporin A (CsA) is considered to be inherently protective in conditions of ischemia, e.g. in hepatic and cardiac tissue. However, investigations of effects of CsA on neuronal tissue have been contradictory, probably because the blood-brain barrier (BBB) is virtually impermeable to CsA. In the present study, we exploited the finding that the insertion of a syringe nee
Objective— Stretch-induced growth of the vascular wall plays a role in hypertension and neointima formation. Its signal pathways involve integrins, cytoskeleton, membrane receptors, and ion channels, some of which are organized in cholesterol-rich, membrane domains such as lipid rafts or caveolae. This study tested the role of rafts/caveolae in stretch-induced vascular growth by manipulation of me
The root/organic soil concentration ratio; R/S) of 50 cationic mineral elements was related to their ionic properties, including ionic radius (r), ionic charge (z), and ionic potential (z/r or z(2)/r). The materials studied were ectomycorrhizal beech (Fagus sylvatica L.) roots and their almost purely organic soil substrate, the O-horizon (mor; raw humus) of a Podzol in South Sweden, developed in a
Streptococcus pyogenes secretes a specific immunoglobulin G (IgG)-protease, SpeB, as well as the IgG glycan-hydrolyzing enzyme EndoS. Here we show that SpeB also degrades IgA, IgM, IgD, and IgE. We also show that EndoS only hydrolyzes the glycan moiety on native but not denatured IgG. Thus, SpeB has a broad immunoglobulin-degrading activity, while EndoS is highly specific for IgG.
This study investigates the importance of dimensionality for the characteristics of simulations performed with cloud-system resolving models (CSRMs). In addition to intrinsic questions related to dimensionality in CSRMs, the issue has gained added interest since CSRMs can be utilized instead of conventional cloud parametrizations to represent deep convection within global climate models. Such CSRM
Dynamic electric (DEA) and mechanical (DMA) analyses were combined to explore the relaxational processes in amorphous and semicrystalline poly(ethylene naphthalene-2,6-dicarboxylate) (PEN) samples. Differential scanning calorimetry measurements were carried out to investigate the crystallinity of the samples following isothermal annealing treatment at 443 K. The two secondary relaxations beta and
The use of folic acid prior to conception is generally recommended for the prevention of birth defects, notably neural tube defects. In a previous study from Sweden, based on interviews of women in early pregnancy, no such effect was found on the general malformation rate, but data for neural tube defects were scarce. Using data from the Swedish Medical Birth Register for the years 1995-2004, 20 8
Biological processes exhibit different behavior depending on the influent loads, temperature, microorganism activity, and soon. It has been shown that a combination of several models can provide a suitable approach to model such processes. In the present study, we developed a multiple statistical model approach for the monitoring of biological batch processes. The proposed method consists of four
An analytical quantitative high-pressure liquid chromatography (HPLC) method was developed for simultaneous determination of all mercaptobenzothiazole derivatives in the mercapto mix patch testing standard. The stability of the mercaptobenzothiazoles constituting the mercapto mix was studied both in petrolatum and in buffer solution at pH 6.5, with and without glutathione. In petrolatum vehicle, d
The purpose of the present study was threefold: (a) to replicate the finding by MacLeod and Rutherford (1992) that low trait-anxious individuals, in contrast to high trait-anxious individuals, show a selective attention away from subliminally presented threat words at elevated levels of stress; (b) to test the hypothesis that this effect is due to individuals with repressive coping-style rather th
This study was aimed at increasing our understanding of environmental and parental factors influencing mode choice for children's journeys to organized leisure activities. Three hundred and fifty-seven Swedish parents of 8-11-year-old children completed a questionnaire and kept a travel diary. The design of urban environment, in which the families lived, was assessed by a group of five experts. By
Periodic signals can be decomposed into sets of sinusoids having frequencies that are integer multiples of a fundamental frequency. The problem of finding such fundamental frequencies from noisy observations is important in many speech and audio applications, where it is commonly referred to as pitch estimation. These applications include analysis, compression, separation, enhancement, automatic t
To study the role of selenium compounds for the quality and nutritional value of meat, speciation of selenium compounds was performed in two muscles from each of seven animal species (chicken, turkey, duck, ostrich, lamb, cattle and pig). Soluble selenium compounds were separated by size-exclusion chromatography (SEC) and detected by inductively coupled plasma-mass spectrometry (ICP-MS). Four sele
