We use metal - organic vapour phase epitaxy for growth investigations of epitaxial nanowires in III - V materials, such as GaAs, GaP, InAs, and InP. In this paper we focus on gold assisted growth of nanowires. The nature of the metal particle - whether it is in the solid or liquid state - is discussed. For InAs and InP we have demonstrated that gold assisted wires can only grow at temperatures whe
The stress field in a finite, edge cracked specimen under load is computed using algorithms based on two slightly different integral equations of the second kind. These integral equations are obtained through left regularizations of a first kind integral equation. In numerical experiments it is demonstrated that the stress field can be accurately computed. Highly accurate stress intensity factors
This paper explores the possibility of providing robots with an 'inner world' based on internal simulation of perception rather than an explicit representational world model. First a series of initial experiments is discussed, in which recurrent neural networks were evolved to control collision-free corridor following behavior in a simulated Khepera robot and predict the next time step's sensory i
The Nordic Power Exchange (Nord Pool), the first multinational exchange for electricity trading, has existed since January 1996. Spot and futures contracts are traded on this exchange and its typical characteristics are very high volatilities as well as non-normally distributed returns. This article looks at electricity futures and how they can be used for short-term hedging of positions taken in
BACKGROUND: Cardiovascular disease (CVD) is the leading cause of death in women after menopause. In essence major risk factors for CVD are similar in women as for men inclusive of serum lipid perturbations. The effects of estrogens and hormone replacement therapy on lipid metabolism is widely discussed and warrant further evaluation especially when combined with other lipid lowering drugs. STUDY D
Many Gram-positive bacteria express surface proteins that bind human plasma proteins. These bacterial proteins, and derivatives of them, are of interest for analysis of bacterial pathogenesis and as immunochemical tools. Well-characterized examples include the IgG-binding reagents staphylococcal protein A and streptococcal protein G, and the recently described streptococcal IgA-binding peptide Sap
This work deals with different types of repair methods for concrete slab on the ground damaged by moisture. Many of the available methods involve some kind of mechanical ventilation of the foundation. The basic principle for all these systems is the same. By establishing air movement through an air-permeable layer below or above the concrete slab, the flowing air can absorb moisture from surroundi
A diagnosis-antibiotic prescribing study initiated by the Swedish Strategic Programme for the Rational Use of Antimicrobial Agents and Surveillance of Resistance was performed in 5 counties in Sweden (total 1,290,000 inhabitants) during 1 week in November 2000. The aims of the study were to analyse diagnoses and antibiotics prescribed for outpatients and to appraise the feasibility of the data col
Alpha 1-antichymotrypsin (ACT) inhibits chymotrypsin-like enzymes, particularly neutrophil cathepsin G. Moreover, ACT in its native form suppresses chemotaxis of neutrophils and decreases neutrophil production of superoxide radicals. We recently showed that Moraxella catarrhalis ubiquitous surface protein (Usp) A1 is able to specifically bind ACT in the context of a novel virulence mechanism. In t
Endotoxaemia is thought to occur in cardiac surgery using extracorporeal circulation (ECC) and a positive correlation has been proposed between the magnitude of endotoxaemia and risk for postoperative complications. We studied the effects of a new endotoxin adsorber device (Alteco(R) LPS adsorber) in patients undergoing cardiac surgery with ECC, with special reference to safety and ease of use. Fi
A new health surveillance protocol for work-related upper-extremity musculoskeletal disorders has been validated by comparing the results with a reference protocol. The studied protocol, Health Surveillance in Adverse Ergonomics Conditions (HECO), is a new version of the reference protocol modified for application in the Occupational Health Service (OHS). The HECO protocol contains both a screenin
The invariant differential cross sections for inclusive π0 and η mesons at midrapidity were measured in pp collisions at s=2.76 TeV for transverse momenta 0.4 < pT< 40 GeV/c and 0.6 < pT< 20 GeV/c, respectively, using the ALICE detector. This large range in pT was achieved by combining various analysis techniques and different triggers involving the electromagnetic calorimeter (EMCal). In particul
Different suggestions for the mechanism governing the narrow stability of the L(3) (sponge) phase have led to a series of debates in recent years. There have been several models developed to describe such a mechanism via thermodynamics. To date, experimental data are insufficient to test present theories. In this study, we revisit the sponge phase with two series of thermodynamic data performed on
Safe languages like Java provide a much more programmerfriendly environment than the low-level languages in which real-time and embedded software have traditionally been implemented. However, an obstacle for widespread use of Java in control applications has been the predictability and real-time performance of garbage collection, and the cumbersome memory management associated with RTSJ NoHeapReal
