Popular Abstract in Swedish Aneurysm är ett sjukdomstillstånd som är känt sedan ca 2000 år före vår tideräkning, och bukaortaaneurysm (bråck på stora kroppspulsådern i buken) beskrivs i publikationer från 1500-talet. På 1800-talet försökte man sig på att behandla med ligering, tyvärr med dåligt resultat, och först på 1920-talet beskrivs den första lyckade ligeringen. Behandling med graftrekonstrukThe incidence of abdominal aortic aneurysms (AAA) is increasing. The risk of rupture is related to diameter. However, rupture may occur also in small AAA. To evaluate the size of an aneurysm when related to the predicted normal aortic diameter might be a better predictor of risk. AAA:s, range 40-55 mm were studied in relation to gender. No difference in AAA diameter was found. However, body surfac

After reactions of uranium atoms with NF3 and PF3 to form the N UF3 and P UF3 molecules, the analogous reaction with AsF3 produced the novel terminal arsenide As UF3. This first molecule with a uranium-arsenic bond was identified from matrix infrared spectra through comparison with spectra of the uranium nitride and phosphide species, with spectra using other metals, and with frequencies computed

Background Organic acid anhydrides are low molecular weight industrial chemicals, able to cause rhinoconjunctivitis and asthma associated with specific IgE against hapten-carrier protein conjugate. Only a proportion of exposed workers develop IgE-associated allergy to acid anhydrides. Objective We determined whether genetic susceptibility, in particular, HLA Class II alleles may be a risk factor.

Variable time-step methods, with general step-size control objectives, are developed within the framework of variational integrators. This is accomplished by introducing discrete transformations similar to Poincares time transformation. While gaining from adaptive time-steps, the resulting integrators preserve the structural advantages of variational integrators, i.e., they are symplectic and mome

OBJECTIVE: To compare survival of patients with breast cancer who had never smoked, were smokers, and who were ex-smokers. DESIGN: Observational study. SETTING: City of Malmo, Sweden. PATIENTS: 792 patients with breast cancer diagnosed between 1977-1986 in the Malmo mammographic screening trial. INTERVENTIONS: Follow-up of breast cancer cases through record-linkage with the Swedish Cause of Death

Popular Abstract in Swedish Elektroencefalogrammet (EEG), dvs mätning av potentialer på skalpen, är en relativt enkel och gammal teknik för att studera hjärnans aktivitet. Trots de stora framstegen inom s k brain-mapping-tekniker på senare år (magnetröntgen, PET, SPECT), är EEG fortfarande ett viktigt verktyg för diagnos. En av dess fördelar gentemot andra tekniker är dess fina tidsupplösning. EtThe thesis treats methods for pattern recognition in multichannel electroencephalogram (EEG) signals, for application to diagnostics of epilepsy. Parts I-IV treat methods for feature extraction and clustering of EEG spikes, occurring between epileptic seizures, and part V presents a method for filtering seizure onset EEG signals. In part I, Hermite functions are used for parametric description of

Excited states of nuclei in the vicinity of Sn-100 have been studied using: the EUROBALL detector array. Gamma-ray lines from Sn-103 have been identified for the first time, and a level scheme of low-lying excited states of Sn-103 has been established. New constraints on energies of single particle orbitals with respect to the Sn-100 core are obtained.

Partial and complete injured median and ulnar nerves caused by fractures of the radius and ulna, respectively, in which the symptoms of nervous injury were induced at the time of fracture are reported. In cases with complete loss of nervous function early exploration should be considered at the time of reposition or plating of the fractured bones, or both, and in patients in whom nervous dysfuncti

Various kinds of subgraph counts have been proposed as important statistics in the social sciences: for instance, in connection with studies of the structural properties of social networks. Since the empirical structure in question often involves an element of randomness, subgraph counts are random variables and, consequently, we need to describe their probabilistic properties. In this paper we gi

Why, how, and with what consequences do national governments delegate political authority to supranational institutions? Contrary to the static conceptions of delegation that dominate the existing literature, this article adopts a dynamic approach, where the stages of the delegation process are integrated into a coherent rational institutionalist framework. With demonstrations from the case of the

A wide divergence has been detected in the telomeric sequences among budding yeast species. Despite their length and homogeneity differences, all these yeast telomeric sequences show a conserved core which closely matches the consensus RAP1-binding sequence. We demonstrate that the RAP1 protein binds this sequence core, without involving the diverged sequences outside the core. in Saccharomyces ca

An increasingly common and effective method for the treatment of atherosclerotic disease in the coronary arteries is percutaneous transluminal coronary angioplasty (PTCA) and stenting. The stents are made of different metals. An increased rate of restenosis when using gold-plated stents has been shown. Contact allergy to gold is common in many countries. Recently, a study has shown an increased ra

We discuss how techniques from multiresolution analysis and phase space transforms can be exploited in solving a general class of evolution equations with limited smoothness. We have wave propagation in media of limited smoothness in mind. The frame that appears naturally in this context belongs to the family of frames of curvelets. The construction considered here implies a full-wave description

Various types of graph statistics for graphs and digraphs are presented as numerators of incomplete U-statistics, with symmetric and asymmetric kernels, respectively. Thus, asymptotic Poisson limits of these statistics are provided by using limit theorems for the sums of dissociated random variables. Several applications to statistical analysis of graphs are given
