Managing cardiovascular risk: the need for change
Life-views and ethical viewpoints among physiotherapy students in Sweden and Turkey - a comparable study
There is a need for a deeper understanding of and discussion about different cultures' influences on life-views and ethical reasoning among professionals within healthcare. A culture can be seen as a set of guidelines, both explicit and implicit, which individuals inherit as members of a particular society, and which tells them how to view the world and how to behave in it in relation to other peo
Genetic similarities between latent autoimmune diabetes in adults, type 1 diabetes, and type 2 diabetes
OBJECTIVE-Latent autoimmune diabetes in adults (LADA) is often considered a slowly progressing subtype of type 1 diabetes, although the clinical picture more resembles type 2 diabetes. One way to improve classification is to study whether LADA shares genetic features with type 1 and/or type 2 diabetes. RESEARCH DESIGN AND METHODS-To accomplish this we studied whether LADA shares variation in the H
Robust tuning procedures of dead-time conpensating controllers
This paper describes tuning procedures for dead-time compensating controllers (DTC). Both stable and integrating processes are considered. Simple experiments are performed to obtain process models as well as bounds on the allowable bandwidth for stability. The DTC's used have few parameters with clear physical interpretation so that manual tuning is possible. Furthermore, it is shown how the DTC's
Robotic Force Control using Observer-based Strict Positive Real Impedance Control
This paper presents theoretical and experimentalresults on observer-based impedance control for forcecontrol without velocity feedback. As the velocity may notavailable to measurement, which is often the case for industrialrobots, an observer was designed to reconstruct velocityin such a way that it be useful for stabilizing feedbackcontrol and to modification of the damping in the impedancerelati
Techno-Economic Evaluation of Bioethanol Production from Three Different Lignocellulosic Materials
The lignocellulosic materials spruce (softwood), Salix (hardwood) and corn stover (agricultural residue) are all potential feedstock for ethanol production. In this study the utilization of these materials for bioethanol production was compared in terms of production cost and energy demand using a process concept based on SO2-catalysed steam pretreatment followed by simultaneous saccharification a
Perfusion abnormalities in pulmonary embolism studied with perfusion MRI and ventilation-perfusion scintigraphy: an intra-modality and inter-modality agreement study
PURPOSE: To compare perfusion magnetic resonance imaging (MRI) and ventilation-perfusion scintigraphy (V-P scan) in the study of perfusion abnormalities in pulmonary embolism (PE) and to compare the PE results to the findings previously reported for pneumonia and chronic obstructive pulmonary disease (COPD), in terms of perfusion abnormalities. MATERIALS AND METHODS: Dynamic contrast-enhanced MR i
Intrinsic viscosity of dispersions of core shell-particles
An analytic solution of the Brinkman and Stokes equations for a rigid sphere surrounded by a porous shell in pure straining flow is presented. The solution permits for an analytic determination of the intrinsic viscosity in the dilutelimiting expansion for the steady shear viscosity. The porous layer, characterized by a thickness and a constant permeability, alters the intrinsic viscosity from the
Prevalence of hip osteoarthritis in Iceland
OBJECTIVE: To assess the prevalence of primary hip osteoarthritis (OA) in Iceland. To compare the prevalence of primary hip OA in Iceland with published rates of primary hip OA for related Scandinavian populations.METHODS: Roentgenographs were examined of 1530 Icelandic people 35 years or older (653 males, 877 females) subjected to colon radiography during the years 1990-1996. The radiographs exam
Sexual dimorphism in lizard body shape: The roles of sexual selection and fecundity selection
Sexual dimorphism is widespread in lizards, with the most consistently dimorphic traits being head size (males have larger heads) and trunk length (the distance between the front and hind legs is greater in females). These dimorphisms have generally been interpreted as follows: (1) large heads in males evolve through male-male rivalry (sexual selection); and (2) larger interlimb lengths in females
Menorrhagia and minor bleeding symptoms in women on oral anticoagulation.
Background Oral anticoagulation (OA) is a common treatment with a known risk of fatal or major bleeding, but also minor bleeding symptoms and menorrhagia can cause substantial discomfort and necessitate medical or surgical interventions. The extent of these side effects is however not previously reported. The objective of this study is to assess the frequency of minor bleeding symptoms and menorrh
Reverse pharmacology and the de-orphanization of 7TM receptors
Approximately 800 genes coding for seven-transmembrane, G-protein-coupled receptors have so far been recognized. In spite of this, many of these receptors are defined by their sequence only, and are therefore classified as orphan receptors. Without knowing what their endogenous ligands are, we lack the information needed to understand their physiological role and hence cannot make use of them as d
Three years of Galileo dust data. II. 1993-1995
Between January 1993 - December 1995, the Galileo spacecraft traversed the interplanetary space between Earth and Jupiter and arrived at Jupiter on 7 December 1995. The dust instrument onboard the spacecraft was operating during most of the time and data from the instrument were obtained via memory readouts which occurred at rates between twice per day and once per week. All events were classified
ACCURATE PREDICTION OF PROTEIN SECONDARY STRUCTURAL CLASS WITH FUZZY STRUCTURAL VECTORS
The prerequisites for accurate prediction of protein secondary structural class (all-alpha, all-beta, alpha+beta, alpha/beta or multidomain) were studied, and a new similarity-based method is presented for the prediction of the secondary structural class of a protein from its sequence. The new method uses representatives of nuclear families as a learning set. For the sequence to be predicted, the
A comparison between batch and fed-batch simultaneous saccharification and fermentation of steam pretreated spruce
In order to improve the process economy it is important to use as high dry matter content as possible in simultaneous saccharification and fermentation (SSF). However, too high dry matter content often gives rise to severe inhibition of the yeast metabolism, due to the increased levels of toxic compounds. The aim of the present work was to increase the fibrous content in SSF of steam pretreated sp
Structural Characterization of Yeast Acidic Ribosomal P Proteins Forming the P1A-P2B Heterocomplex
Acidic ribosomal P proteins form a distinct lateral protuberance on the 60S ribosomal subunit. In yeast, this structure is composed of two heterocomplexes (P1A-P2B and P1B-P2A) attached to the ribosome with the aid of the P0 protein. In solution, the isolated P proteins P1A and P2B have a flexible structure with some characteristics of a molten globule [Zurdo, J., et al. (2000) Biochemistry 39, 89
Ischemia of rat stomach mobilizes ECL cell histamine
Microdialysis was used to study how ischemia-evoked gastric mucosal injury affects rat stomach histamine, which resides in enterochromaffin-like (ECL) cells and mast cells. A microdialysis probe was inserted into the gastric submucosa, and the celiac artery was clamped (30 min), followed by removal of the clamp. Microdialysate histamine was determined by enzyme-linked immunosorbent assay. In addit
Combinations of indigestible carbohydrates affect the short-chain fatty acid content in the hind-gut of rats
The fermentability and pattern of short-chain fatty acids (SCFA) formed in the hindgut of rats given various combinations of dietary fibers (DF) and resistant starch (RS) were investigated. Highly fermentable indigestible carbohydrates, i.e., guar gum (GG), pectin (Pec) and high amylose cornstarch (HAS), and a DF with a relatively high resistance to fermentation, i.e., wheat bran (WB), were includ
