We study oscillator chains of the form phi(k)=omega(k)+K[Gamma(phi(k-1)-phi(k))+Gamma(phi(k+1)-phi(k))], where phi(k)is an element of[0,2pi) is the phase of oscillator k. In the thermodynamic limit where the number of oscillators goes to infinity, for suitable choices of Gamma(x), we prove that there is a critical coupling strength K-c, above which a stable frequency-entrained state exists, but be

Abdominal trauma occurring in persons older than 60 years over a 30-year period (1950-79) in a well defined region of Sweden was reviewed. The 177 patients comprised 12.5% of the total with abdominal trauma during that period. Road traffic accidents were the main cause of trauma (48% of cases). The incidence of motor-car accidents rose sharply during the first two decades of the study. Injuries to

Popular AbstractDenna sammanläggningsavhandling tar upp olika aspekter vid det regionala innovationssystemet i en urban kontext. Det övergripande syftet är att identifiera faktorer som kan förklara hur regionala innovationssystem faktisk fungerar i en urban agglomeration. Detta är gjort genom att se på innovationsdynamiken och innovationsaktiviteten i Oslo regionen, och genom att se hur två olika The dissertation is based on a collection of papers addressing different aspects of regional innovation systems in an urban context. The overall aim is to find explanatory factors behind the workings of regional innovation systems in urban agglomerations by looking at the innovation dynamics and innovation outcomes of the Oslo region, and secondly, by analysing how two diverse subsets of economic

Abstract Many studies that investigate pollutant levels, or use stable isotope ratios to define trophic level or animal origin, use different standard ways of sampling (dorsal, whole filet or whole body samples). This study shows that lipid content, ΣPCB and δ13C display large differences within muscle samples taken from a single Atlantic salmon. Lipid- and PCB-content was lowest in tail muscles,

Objective To determine whether subjective evaluation of the morphology of the vessel tree of ovarian tumors, as depicted by three-dimensional (3D) power Doppler ultrasound, can discriminate between benign and malignant ovarian tumors, and whether it improves characterization compared with using gray-scale ultrasound imaging alone. Methods A consecutive series of 104 women scheduled for surgical r

Objective The effect of salt restriction on blood pressure is under intense debate. We tested the effect of 100 mmol salt reduction on ambulatory blood pressure (ABP) in 46 Swedish individuals, 39 of whom completed the study, using a double-blind, placebo-controlled, crossover design. Furthermore, we tested whether the basal plasma concentration of renin or N-terminal atrial natriuretic peptide (N

BACKGROUND: Proper treatment of lymph node-negative breast cancer depends on an accurate prognosis. To improve prognostic models for this disease, we evaluated whether an immunohistochemical marker for proliferating cells, Ki-S2 (a monoclonal antibody that binds to a 100-kd nuclear protein expressed in S, G2, and M phases of the cell cycle), is an accurate indicator of prognosis.METHODS: We studie

The proliferative rate in normal breast epithelium from 58 women undergoing reduction mammoplastics was studied using the formalin resistant antibody Ki-S5, and related to age at operation, menstrual cycle phase, family history of breast cancer, height and weight, parity, and hormonal use. The breast tissue from women operated on in the luteal menstrual cycle phase (day 15-28 among oral contracept

OBJECTIVE: To compare the attitudes of a large sample of obstetricians from eight European countries toward a competent woman's refusal to consent to an emergency cesarean delivery for acute fetal distress. METHODS: Obstetricians' attitudes in response to a hypothetical clinical case were surveyed through an anonymous, self-administered questionnaire. The sample included 1,530 obstetricians (respo

The Sahel region has been identified as a "hot spot'' of global environmental change, but understanding of the roles of different climatic and anthropogenic forcing factors driving change in the region is incomplete. We show that a process-based ecosystem model driven by climatic and atmospheric CO2 data alone closely reproduces the satellite-observed greening trend of the Sahel vegetation and its

Twelve research groups participated in the ISOBM TD-3 Workshop in which the reactivity and specificity of 83 antibodies against prostate-specific antigen (PSA) were investigated. Using a variety of techniques including cross-inhibition assays, Western blotting, BIAcore, immunoradiometric assays and immunohistochemistry, the antibodies were categorized into six major groups which formed the basis f

Popular Abstract in Swedish Svensk populärvetenskaplig sammanfattning Kvartärtidens avlagringar döljer mycket och detaljerad information om palaeoklimatet och de lämpar sig därför väl för att modellera palaeoklimatets förändringar. Inlandsisar är av avgörande betydelse för klimatet under kvartärtiden. Deras tillväxt och avsmältning beror till stor del på klimatiska faktorer, såsom temperatur, nedeThis thesis presents results from studies on geomorphology, lithostratigraphy and ice flow patterns during the final termination and deglaciation of the last Scandinavian Ice Sheet in NE Germany. Ice flow patterns derived from till fabrics and glaciotectonical data indicate that short-lived marginal domes had formed during the advance and the retreat of the last Scandinavian Ice Sheet in NE German

The process simulator ASPEN PLUS was used for simulation of an ethanol production process based on enzymatic hydrolysis of lignocellulosic materials. Various process configurations were studied to increase the overall yield of ethanol and to reduce the energy consumption in the process. An increased utilization of the pentosan fraction was achieved by a complex recycling of streams in the process.
