The European Pre-Standard for protective clothing against cold ENV 342:1998 suggests that the testing of thermal insulation should be made on a moving thermal manikin. In this way the value can be used to match requirements specified by the IREQ-method or as realistic input for prediction of thermal stress in other standards. It is known from prior work that insulation values measured with human s
Purpose – The purpose of this paper is to propose a framework of the potential benefits of asset visibility in the context of returnable transport items (RTI), and uses the framework to examine the effect of asset visibility on the management of RTI systems. Design/methodology/approach – A combined case study and simulation approach was used. A case study was performed to identify and understand
Defect reactions associated with the elimination of divacancies (V-2) have been studied in n-type Czochralski (Cz) grown and float-zone (FZ) grown Si crystals by means of conventional deep-level transient spectroscopy and high-resolution Laplace deep-level transient spectroscopy (LDLTS). Divacancies were introduced into the crystals by irradiation with 4 MeV electrons. Temperature ranges of the di
Background: Termites of the subfamily Macrotermitinae live in a mutualistic symbiosis with basidiomycete fungi of the genus Termitomyces. Here, we explored interaction specificity in fungus-growing termites using samples from 101 colonies in South-Africa and Senegal, belonging to eight species divided over three genera. Knowledge of interaction specificity is important to test the hypothesis that
The effect of formally next-to-leading contributions to the CCFM evolution equation are discussed.
Objective. Insulin resistance is associated with progression of atherosclerosis. We assessed the effect of 12 months of treatment with rosiglitazone (RSG) on the progression of carotid intima-media thickness (IMT) in people with type 2 diabetes mellitus (T2DM) or the insulin resistance syndrome (IRS). Design. Randomized, double-blind, placebo-controlled trial. Setting. Malmo University Hospital, M
In an effort to increase our knowledge of the optimal use of serum cystatin C and creatinine as glomerular filtration rate (GFR) markers, these variables, as well as lean tissue mass and GFR, were determined in a population of 42 healthy young adults (men and women with normal GFR). Dual-energy X-ray absorptiometry and measurement of the plasma clearance of iohexol were used to measure lean tissue
A common methodology for analyzing metalworking fluid (MWF) aerosols in workplace air is based on gravimetry before and after organic solvent extraction of the MWFs from a suitable collection filter: Because MWFs have different chemical and physical properties, various mixtures of organic solvents have been used to extract the MWFs from their collection device. An alternative to organic solvents,
Mathematical models are frequently used in control engineering for analysis, simulation, and design of control systems. Many of these models are accurate but may for some tasks be too complex. In such situations the model needs to be simplified to a suitable level of accuracy and complexity. There are many simplification methods available for models with known parameters and dynamics. However, for
I syfte att utveckla en ny provningsmetod för golvmaterial/system på betong beträffande fläkningskraft, relativ fuktighet och emissioner av organiska ämnen studerades 60 provkroppar. Provkroppen, tre identiskt lika av vardera i syfte att studera noggrannheten, byggdes upp som ett verkligt golv inuti en stålform (standard ventilationsdelar i stål - lock och fläns) vilken satt kvar under hela testpe
1 This study examines the importance of mitogen-activated protein kinases (MAPKs) in upregulation of endothelin type B (ETB) receptors. 2 Rat middle cerebral arteries (MCAs) were incubated for 24 h with or without kinase inhibitors. Vessel segments were mounted in myographs and the contractile responses to endothelin-1 (ET-1; ETA and ETB receptor agonist) and sarafotoxin 6c (S6c; ETB receptor agon
Excited states in Ar-38 have been investigated by means of the heavy-ion fusion-evaporation reaction Si-28 +O-16. The level scheme reveals a subtle interplay between spherical, deformed, and superdeformed shapes. Large-scale shell-model calculations in the sd-fp space are invoked to study the microscopic aspects of deformation and shape changes.
Stacked stromatoporoid-dominated biostromes of the Ludlow-age Hemse Group (Silurian) in eastern Gotland, Sweden, are 0.5-5 m thick and a few tens of metres to >1 km in lateral extent. They form one of the world's richest Palaeozoic stromatoporoid deposits. This study compiles published and new data to provide an overall facies model for these biostromes, which is assessed in relation to possible m
Abstract Partitioning in aqueous polymer two-phase systems of polyethylene glycol and dextran was used to detect and compare cell-surface charge and cell-surface hydrophobicity of Aeromonas hydrophila, A. caviae, A. sobria, Vibrio cholerae, and V. anguillarum strains. These strains have cell-surface components that bound either native or thermally denatured type I collagen (i.e., a mixture of the
Health-health analysis (HHA) focuses on statistical lives themselves as a numeraire. The underlying principle is that the expected gains in health and safety of reduced risks in one area may result in increasing risks somewhere else in society. By reducing one risk other risks may increase due to changed individual behaviour. In addition to this direct effect, another indirect effect will also be
