Industrial process signals do affect one other. However, causal dependencies, or corre-lation, and thereby consequences of control actions cannot always be understood by the operator, which may lead to accidents. Models explain dependencies and are mostly built on process knowledge and blueprints, while causalities are visible in the measurements and ought to be used to increase process under-stan

Renovascular hypertension (RVH) is the direct consequence of renal artery stenosis (RAS). Most RAS patients have dis¬seminated atherosclerosis, with > 6 times greater risk of cardiovascular death than age-matched controls. Elevated levels of angiotensin II and aldosterone lead to detrimental effects both through hypertensive injury and activation of profibrotic and atherosclerotic pathways. The re

Background: Patients who undergo treatment may suffer preventable medical errors. Some of these errors are due to diagnostic imaging procedures. Purpose: To compare the frequency of diagnostic errors in different age groups in an urban European population. Material and Methods: A total of 19 129 reported radiologic examinations were included. During a 6-month period, the analyzed age groups were:

ABSTRACT: BACKGROUND: Robot-assisted laparoscopy (RL) is used in a wide range of operative interventions, but the advantage of this technique over conventional laparoscopy (CL) remains unclear. Studies comparing RL and CL are scarce. The present study was performed to test the hypothesis that maiden users master surgical tasks quicker with the robot-assisted laparoscopy technique than with the con

PURPOSE: This study identified relationships between occupational factors and health and well-being among individuals with persistent mental illness. METHODS: There were 103 subjects assessed in regards to time spent in different occupations, activity level, satisfaction with daily occupations, and experienced occupational value. The health-related variables were self-rated health, quality of life

The movement of water in a large (3.5 m(3)) undisturbed sample of 22-year-old municipal solid waste has been modeled using a kinematic wave approximation for unsaturated infiltration and internal drainage. The model employs a two-parameter power expression as macroscopic flux law. The model parameters were determined and interpreted in terms of the internal geometry of the waste medium by fitting

In the literature, there are several different suggestions as to when the first postoperative pin-site care should be carried out to best prevent pin-site infections during the treatment by external fixation. In a cohort study, we compared the use of antibiotics and complications in patients where the theatre dressing was changed during the first postoperative week with patients where the theatre

This paper describes and compares university education and training, the procedures for licensing and the specialist training systems for professional psychologists in the Nordic countries Finland, Norway and Sweden. The interscandinavian and European regulations and agreements affecting mobility are presented. The presented systems are compared to each other and a discussion follows on the topics

The use of mobility devices, such as walking sticks and rollators, increases during the ageing process. Our aim was to explore how very old single-living Swedish women experience the use of mobility devices over time, in relation to everyday occupation. A multiple case study strategy involving quantitative and qualitative data was used. The findings indicate that the use of mobility devices, rolla

Physical bounds on the directivity Q-factor quotient and optimal current distributions are determined for antennas of arbitrary shape and size using an optimization formulation. A variational approach offers closed form solutions for small antennas expressed in the polarizability of the antenna structure. Finite sized antennas are solved using Lagrangian parameters in a method of moments formulati
