The local density theory is developed by Hohenberg, Kohn and Sham is extended to the spin polarized case. A spin dependent one- electron potential pertinent to ground state properties is obtained from calculations of the total energy per electron made with a `bubble' (or random phase) type of dielectric function. The potential is found to be well represented by an analytic expression corresponding
Due to political conflicts, the northern part of Cyprus is being under economical crisis. This is employed by environmental problems such as non-organised improvement of residential areas and their effects on habitat. Especially, three main cities where 75 percent of population is crowded, is seriously under the threat of sewerage problems. In this study the comparisons for available sewerage syst
The state authorities in Germany used to fund public sector research without controlling the performance of the research units. This has changed during past decade, where the dominant mechanism by which formerly unconditional state funds are allocated nowadays is indicator-based performance measurement. The indicator sets used to measure the research-related performance in the German public scienc
This paper analyses the effect of variety and intensity of knowledge on the innovation of regions. Employing data for Swedish functional regions, the paper tests the role of the variety (related and unrelated) and intensity of (1) internal knowledge generated within the region and also (2) external knowledge networks flowing into the region in explaining regional innovation, as measured by patent
Background: Preterm birth remains the major risk factor for the development of intraventricular haemorrhage, an injury that occurs in 25% of very low birth weight infants. Intraventricular haemorrhage is thought to be venous in origin and intrinsic thromboses in the germinal matrix are likely to play a triggering role. Heparin activates antithrombin and promotes the inactivation of thrombin and ot
The commissioning and operations planning for the European Spallation Source is currently being defined. It is foreseen that the ESS will begin to deliver beam on target by mid 2019, something which is urging a well structured and thought through plan both for commissioning and operations. In this paper we will discuss the plans for beam physics operational software, priorities and software servic
The linear filtering, prediction and smoothing problems as well as the linear quadratic control problems can very generally be formulated as operator equations using basic linear algebra.The equations are of Fredholm type II, and they are difficult to solve directly.It is shown how the operator can be factorized into two Volterra operators using a matrix Riccati equation. Recursive solution of the
Synovial proliferation in rheumatoid arthritis causes capsular distension, destruction of tendons and ligaments, and erosion of bone. The classic deformities in rheumatoid arthritis, like boutonnière or swan neck, are not consistent, and each patient may have his or her own pattern of deformities. The anatomic arrangement of the tendons enables motion of the proximal interphalangeal (PIP) joint is
A high resolution soft X-ray monochromator for the 550 MeV MAX storage ring is described. The instrument combines a plane elliptical premirror collecting a large (10 mrad) horizontal angle of radiation and a modified version of the well-known SX-700 plane grating monochromator (PGM). The modification consists of changing the original ellipsoidal focussing mirror to a plane elliptical mirror. There
Background. Allergy nurses are exposed to allergens and respiratory irritants, and there are no national guidelines addressing personnel safety when working with these agents. Objective. To investigate the prevalence of allergies, asthma, and hypersensitivity symptoms among allergy nurses and the use of protective equipment and measures when working with allergen concentrates and respiratory irrit
Most research on global governance has focused either on theoretical accounts of the overall phenomenon or on empirical studies of distinct institutions that serve to solve particular governance challenges. In this article we analyze instead “governance architectures,” defined as the overarching system of public and private institutions, principles, norms, regulations, decision-making procedures a
Systemic lupus erythematosus (SLE) is a severe autoimmune connective tissue disease. Our current knowledge about the serum proteome, or serum biomarker panels, reflecting disease and disease status is still very limited. Affinity proteomics, represented by recombinant antibody arrays, is a novel, multiplex technology for high-throughput protein expression profiling of crude serum proteomes in a hi
The Cochrun-Grabel (C-G) method, an algorithm for finding the characteristic polynomial of a circuit containing reactances, has so far been restricted to circuits not employing mutual inductances. In this paper we present an intuitive, yet rigorous, proof of the Cochrun-Grabel method for a general RLC circuit, and we extend the method to allow the analysis of an RLC circuit containing mutual induc
A new type of chip based microelectrode for acute electrophysiological recordings in the CNS has been developed. It's designed to be adaptable to a multitude of specific neuronal environments, in this study the cerebellar cortex of rat and cat. Photolithographically patternened SU-8 is used to yield flexible and biocompatible penetrating shanks with gold leads. Electrodes with an impedance of abou
