North Eastern Europe and Swedish great power policy: Reflections on historical consciousness

The article discusses the usefulness of the concept of North Eastern Europe. It was developed as a cognitive instrument in order for historical analysis to focus on social structures and processes rather than on states. Swedish historical consciousness is linked to the history of the seventeenth century, not least thanks to the historical novels by Peter Englund, Sweden of those times was a multin

Synthesis of gamma-carboxylated polypeptides by alpha-cells of the pancreatic islets

gamma -Carboxylated proteins were detected in normal human pancreas by immunohistochemistry with a monoclonal antibody (M3B) specific for gamma -carboxyglutamyl residues, Staining appeared to be localized to the glucagon-secreting alpha -cells in the islets of Langerhans, Consistent with this, sections from a glucagonoma were stained much more intensely with the M3B antibody than those from an ins

A notion of independence via moving targets

We introduce a new notion of independence based on the Borel-Cantelli lemma. We study this characteristic in the context of i.i.d. stochastic processes and processes driven by equilibrium dynamics.

Percutaneous placement of stents in chronic iliac and aortic occlusive disease

OBJECTIVES: to evaluate the long-term results of stenting in iliac and aortic occlusive disease and identify factors predicting clinical outcome. Design: retrospective study. MATERIALS AND METHODS: 82 patients (87 limbs) with stenoses (n =63) and occlusions (n =24) in the aortoiliac segment were treated with stents. 81 lesions involved the iliac arteries, 3 the infrarenal aorta and 3 the aortic bi

Local variation in Rana termporaria egg and clutch size: Adaptations to pond drying?

Egg and clutch size variation among populations of common frogs (Rana temporaria) were studied in 14 ponds in Sweden. Also two secondary indices, clutch mass and allocation tactics (egg size3/clutch size) were studied. For all four characters there was a pond-wise correlation between the values across the two study years. All characters differed among ponds and all but allocation tactics differed

Towards the smart windows - Progress in electrochromics

Electrochromic devices have the ability to produce reversible and persistent changes of their optical properties. The phenomenon is associated with joint ion and electron transport into/out of an electrochromic thin film, in most cases being a transition metal oxide. This paper outlines the various applications of such devices in smart windows suitable for energy-conscious architecture, in variabl

A semiautomatic task-oriented programming system for sensor-controlled robotised small-batch and one-off manufacturing

A task-oriented system structure has been developed. In normal industrial robot programming, the path is created and the process is based on the path. Here a process-focused method is proposed, where a task can be split in subtasks, one for each part of the process with similar process-characteristics. By carefully encapsulating the information needed to execute a sub-task, this component can be r

Symmetry of magnetoconductance fluctuations of quantum dots in the nonlinear response regime

We investigate the symmetry of magnetoconductance fluctuations of phase-coherent, two-terminal quantum dots in the nonlinear regime of transport. Specifically, we consider open, ballistic quantum dots (electron billiards) with and without symmetry axes parallel and perpendicular to the current direction and formulate a set of novel symmetry relations not observed in devices with lower symmetry. We

Germline E-cadherin mutations in familial lobular breast cancer

Background: The cell surface glycoprotein E-cadherin (CDH1) is a key regulator of adhesive properties in epithelial cells. Germline mutations in CDH1 are well established as the defects underlying hereditary diffuse gastric cancer (HDGC) syndrome, and an increased risk of lobular breast cancer (LBC) has been described in HDGC kindreds. However, germline CDH1 mutations have not been described in pa

Kinetics of lung clearance of 99mTc-DTPA in smoking patients with sarcoidosis compared to healthy smokers.

Investigation of lung clearance of 99mTc-labelled diethylene triamine penta-acetic acid (DTPA) in smoking sarcoid patients has been impeded by difficulties to differ between pathology of clearance kinetics caused by sarcoidosis and by smoking. This study explores the kinetics of lung clearance of 99mTc-DTPA in 15 current smokers with intrathoracic sarcoidosis. The results are compared with finding

Energy localization in two chaotically coupled systems

We set up and analyze a random matrix model to study energy localization and its time behavior in two chaotically coupled systems. This investigation is prompted by a recent experimental and theoretical study of Weaver and Lobkis on coupled elastomechanical systems. Our random matrix model properly describes the main features of the findings by Weaver and Lobkis. Due to its general character, our

Performance Analysis and Optimization via Simulation

A large amount of scientific work has been carried out to enhance the methods used for design and control of technical systems. For many of these systems, the main objective is to utilize the limited resources in an optimal way. Different simulation techniques have, in many cases, been successfully applied to the analysis. When working with technical systems, it is important to have a common notat
