A methodology for safety verification of continuous and hybrid systems using barrier certi.ficates has been proposed recently. Conditions that must be satisfi.ed by a barrier certi. cate can be formulated as a convex program, and the feasibility of the program implies system safety in the sense that there is no trajectory starting from a given set of initial states that reaches a given unsafe regi
Vehicle ingress is an important automotive industry issue. End-users and production line assemblers perform similar ingress tasks. In this study, comparisons were made of the car ingress motion in 40 subjects of different statutes, acting both as assemblers and end-users. Half of the subjects were under 28 years of age and the remaining were over 60. Results show no significant differences in moti
The surface compositions of poly(styrene-b-ethylene oxide) and poly(styrene-g-ethylene oxide) films were found to be largely determined by the nature of the poly(ethylene oxide) (PEO) chain ends. Angle-dependent X-ray photoelectron spectroscopy revealed that polystyrene (PS) dominated the surfaces of the copolymers having PEO chain ends terminated by hydroxyl groups (SEO). Also, the PEO content de
Aims/hypothesis Post-translational modifications, such as isomerisation of native proteins, may create new antigenic epitopes and play a role in the development of the autoimmune response. Protein-L-isoaspartate (D-aspartate) O-methyltransferase (PIMT), encoded by the gene PCMT1, is an enzyme that recognises and repairs isomerised Asn and Asp residues in proteins. The aim of this study was to asse
Hypoglycaemia (median venous blood glucose 1.8 mmol/l; range 1.6-2.3) was induced by an intravenous infusion of regular insulin in eight patients with Type 1 (insulin-dependent) diabetes mellitus (age 28.0 +/- 7.4 years; mean +/- SD, duration 15.5 +/- 5.1 years) and in 12 age-matched healthy male control subjects. Multi-channel frequency analysis of electroencephalogram (electrophysiologic brain m
A central element in contemporary regional development strategies is the ability for regions to attract and retain talented people. The underlying argument is that by attracting talented people, regions are better geared to meet the demand of competences of the knowledge economy and become more competitive. This article focuses on the migration of the creative class in Sweden. Three questions, cen
The amino-terminal hypervariable region (HVR) of streptococcal M protein is required for the ability of this virulence factor to confer phagocytosis resistance. The function of the HVR has remained unknown, but the finding that many HVRs with extremely divergent sequences bind the human complement regulator C4b-binding protein (C4BP) has suggested that this ligand may play a role in phagocytosis r
Eosinophils may be found at sites of inflammation, for example in asthma, allergy and helminthic infestation, but their role in human inflammatory disease is unclear. In the present study, we investigated the presence of alpha-1-antitrypsin (AAT), a serine proteinase inhibitor, in human eosinophils. When lysates of highly purified eosinophils were subjected to Western blotting, with a chemilumines
The relationship between obesity and alterations in adipose tissue metabolism and lipid transport was studied in fourteen obese subjects before and after a weight reduction of 4-22 kg. Blood glucose and plasma insulin patterns after peroral glucose intake improved significantly, and plasma glucagon levels decreased markedly after treatment. Plasma triglyceride and total cholesterol levels were not
Bone-anchored percutaneous titanium implants have become a well-established clinical procedure with a low incidence of adverse reactions. However, passage through the skin leads to a breach in the barrier to exogenous pathogens. In the present study, monoclonal antibodies were used to investigate the distribution of lymphocyte subpopulations in the soft tissue around such implants. Eight biopsies
The glycaemic index (GI) concept is based on the difference in blood glucose response after ingestion of the same amount of carbohydrates from different foods, and possible implications of these differences for health, performance and well-being. GI is defined as the incremental blood glucose area (0-2 h) following ingestion of 50 g of available carbohydrates in the test product as a percentage of
Differences in physiological functioning in the hypothalamus-pituitary-adrenal cortex axis and the autonomic nervous system have been suggested to contribute to many of the health differences that may be observed between men and women as well as being relevant for the development of musculoskeletal pain. To clarify whether men and women with identical work tasks reacted differently when doing work
The copper-binding cellular prion protein (PrPC) and the heparan sulphate (HS)-containing proteoglycan glypican-1 (Gpc-1) can both be attached to lipid rafts via their glycosylphosphatidylinositol anchors, and copper ions stimulate their cointernalization from the cell surface to endosomes. The prion protein controls cointernalization and delivers copper necessary for S-nitrosylation of conserved
Background: The purpose of this study was to evaluate the incidence and the long-term results of closed uncomplicated Mason type-II and III fractures in a defined population of adults. Methods: Seventy women and thirty men who were a mean of forty-seven years old when they sustained a fracture of the radial head or neck (a Mason type-II fracture in seventy-six patients and a Mason type-III fractu
The three superdeformed (SD) bands in Ce-132 and the two SD bands in Ce-131 have been extended to higher spin following experiments with the EUROBALL IV spectrometer. The two SD bands in 131Ce have been linked together. However, despite the relatively high population intensity of the bands ( up to 5% of the respective channel), it has not been possible to unambiguously link any of the five SD band
The commercially available preparation of beta-galactosidase from Bacillus circulans, known as Biolacta FN5, has been extensively used in the production of prebiotic galactooligosaccharides (GOS). This study focuses on characterizing the production of GOS in two reaction systems: 10% lactose (w/v) in buffer and skim milk. Analysis of the temperature dependence of the GOS yield along with the relat
Carbon fluxes between natural ecosystems and the atmosphere have received increased attention in recent years due to the impact they have on climate. In order to investigate independently how soil moisture and temperature control carbon fluxes into and out of a dry subarctic dwarf shrub dominated heath, monoliths containing soil and plants were incubated at three different moisture levels and subj
Transportation of yellowtail kingfish (Seriola lalandi Valenciennes) juveniles from hatchery to on-growing operations in New Zealand exposes the fish to significantly elevated carbon dioxide (CO2) concentrations. Experiments were undertaken to assess metabolic and haematological stress responses after a 5 h period of hypercapnia followed by recovery in normocapnia. Mortality was low (0.5%) and sec
