Patients often worry considerably about biomedically mild and self-limiting conditions. A previous study on non-selected primary care patients showed that this could be partly explained by frequent associations with cases of serious illness in their family histories. This study further investigated these phenomena in middle aged men with a recent diagnosis of hypercholesterolaemia. Sixty-three out

Introduction Night nurses carry overall nursing responsibility for approximately half the time that patients spend in hospital. However, there is a paucity of literature that focuses on nursing care provided at night. Aim The aim of this study was to evaluate nursing care provided at night from the perspective of both nurses and patients. Methods The study, which had an evaluative and a comparativ

A photon echo experiment has been performed using accumulated highly attenuated laser pulses. We show experimentally that the photon echo process can be performed with, on the average, less than one photon in each pair of excitation pulses. The results support an interpretation where this nonlinear process can be performed with, on the average, less than one photon shared between two of the optica

A single detailed kinetic mechanism for the oxidation and combustion of n-decane and n-heptane has been written by means of an automatic mechanism generator ( REACTION) developed in our laboratory. It shows a good prediction of the ignition delay time versus temperature for the oxidation of n-decane at 13 and 50 bar and n-heptane at 13 and 40 bar for different equivalence ratios. The n-decane/n-he

A parasite's shift to a new host may have serious evolutionary consequences, since host switching usually is associated with a change in virulence and may lead to the evolution of emerging diseases. This phenomenon remains insufficiently studied in wildlife. Here, we combine microscopic examination of blood films and PCR-based methods to investigate the natural host specificity of Haemoproteus and

Second forerunner approximations to the transmission and reflection kernels for a temporally dispersive, nonmagnetic, isotropic slab are obtained. Numerical results are presented for two different dispersion models and are compared with the second forerunner approximations. Finally, transmission and reflection kernels are used to reconstruct the first susceptibility moments of the material of the

This paper presents theory related to stability analysis and stability criteria relevant for observer-based feedback control systems. To this purpose, a special formulation of the Yakubovich-Kalman-Popov (YKP) lemma is provided. We exploit that controllability is not necessary for existence of Lur'e-Lyaptinov functions as used in stability criteria. Constructive means for dynamic output feedback s

The Euro50 is a proposed 50 m optical and infrared telescope. It will have thousands of control loops to keep the optics aligned under influence of wind, gravity and thermal loads. Cross-disciplinary integrated modeling is used to study the overall performance of the Euro50. A sub-model of the mechanical structure originates from finite element modeling. The optical performance is determined using

A class of piecewise affine hyperbolic maps on a bounded subset of the plane is considered. It is shown that if a map from this class is sufficiently area-expanding then almost surely this map has an absolutely continuous invariant measure.

Hur ser smärtan ut? Smärtan känns. Det vet varje människa. Men hur förhåller det sig med dess synlighet? Går smärtan att avbilda? ”I wanted to paint the scream more than the horror”, förklarade Francis Bacon, smärtans och fasans okrönte mästare som på duk efter duk avbildade skrikande, ångestridna och vanställda kroppar. Och är det inte precis så det förhåller sig med våra försök att avbilda smärt

Miniaturized liquid chromatography nanoseparation in combination with minigel fractionation of human primary cell nuclei is presented. We obtained high-sensitivity and high-throughput identification of expressed proteins by subcellular fractionation and nanocapillary liquid chromatography interfaced to both electrospray ionization (ESI)- and matrix-assisted laser desorption/ionisation (MALDI) tand

BACKGROUND. The purpose of the current study was to evaluate the effectiveness of a prostate carcinoma screening program in which serum prostate-specific antigen (PSA) levels were measured. METHODS. From a group of 20,000 men born between January 1, 1930, and December 31, 1944, 10,000 men were randomized into a screening group and 10,000 were randomized into a control group. Patients in the screen

The aim of this study was to assess the impact of the degree of difficulty and quality of hernia repair, as perceived by the surgeon, and operative time on the reoperation rate. All hernia repairs performed during the period 1994-1995 at the Department of Surgery, University Hospital of Lund, Sweden, were recorded prospectively. The degree of difficulty and the degree of difficulty in relation to

District heating systems using cogeneration, as well as local fuel-based and electric heating systems for detached houses, are analysed. The analysis includes the whole energy system, from the natural resource to the end user, with respect to primary energy use, emission and cost. The end-use technologies studied are heat pumps, resistance heaters and boilers. It was assumed that the base-load ele

Photosynthetic electron transport is coupled to ATP synthesis. This process – photosynthetic phosphorylation – proceeds by several alternative electron-transport pathways in isolated chloroplasts. The question: ‘Which of these works in real life?’ has long occupied students of photosynthesis. Recent results from structural biology and genomics suggest that the answer is ‘All of them’. The interpla

Aims. To study the influence of low-intensity solution-focused family therapy with obese and extremely obese pediatric subjects on body mass index (BMI) z-scores and self-esteem. Materials and Methods. Fifty-four obese children, aged 6-17 years, were referred to an outpatient obesity clinic. The families received solution-focused family therapy provided by a multidisciplinary team. Height and weig

A recently developed method for quantitative assessment of regional lung ventilation was employed for the study of posture-dependent ventilation differences in rats. The measurement employed hyperpolarized 3He MRI to detect the build-up of the signal intensity after increasing numbers of 3He breaths, which allowed for computation of a regional ventilation parameter. A group of six anesthetized rat
