Determination of heat loss from the feet and insulation of the footwear

This study compared the methods of determining the footwear insulation on human subjects and the thermal foot model. Another purpose was to find out minimal number of measurement points on human foot that is needed for insulation calculation. Bare foot was tested at three ambient temperatures on 6 subjects. Three types of footwear were tested on 2 subjects. The mean insulation for bare foot obtain

In vivo testing of the protection provided by non-latex gloves against a 2-hydroxyethyl methacrylate-containing acetone-based dentin-bonding product

In dentistry, allergic contact dermatitis to acrylates and allergic contact urticaria to latex are important occupational hazards. There is a need to identify non-latex gloves which are suitable for dental work but at the same time provide adequate protection against acrylate monomers. In a previous study, a new open-chamber system was used for testing the in vivo protection of 6 different gloves

Novel gamma-carboxyglutamic acid-containing peptides from the venom of Conus textile

The cone snail is the only invertebrate system in which the vitamin K-dependent carboxylase (or gamma-carboxylase) and its product gamma-carboxyglutamic acid (Gla) have been identified. It remains the sole source of structural information of invertebrate gamma-carboxylase substrates. Four novel Gla-containing peptides were purified from the venom of Conus textile and characterized using biochemica

Distribution of iodine 125-labeled alpha1-microglobulin in rats after intravenous injection

The 28-kd plasma protein alpha(1)-microglobulin is found in the blood of mammals and fish in a free, monomeric form and as high-molecular-weight complexes with molecular masses above 200 kd. In this study, iodine 125-labeled free and high-molecular weight rat alpha(1)-microglobulin (a mixture of alpha(1)-microglobulin/alpha(1)-inhibitor-3 and alpha(1)-microglobulin/fibronectin complexes) were inje

Channel models for ultrawideband personal area networks

This article describes the modeling of ultra-wideband wireless propagation channels, especially for the simulation of personal area networks. The IEEE 802.15.3a standards task group has established a standard channel model to be used for the evaluation of PAN physical layer proposals. We discuss the standard model, the measurements that form its basis, and the possibilities for future improvements

Modelling steam drying of a single porous ceramic sphere: Experiments and simulations

In order to investigate and describe the drying kinetics occurring in a porous material during superheated steam drying, a model was developed based on the fundamental transport equations for mass and heat. The driving forces in the model are gradients of moisture, temperature and pressure. The transport coefficients employed were either measured experimentally or were derived theoretically from t

The NorduGrid project: using Globus toolkit for building GRID infrastructure

The NorduGrid is the pioneering Grid project in Scandinavia. The purpose of the project is to create a Grid computing infrastructure in Nordic countries. The cornerstone of the infrastructure adopted at NorduGrid is the Globus toolkit developed at Argonne National Laboratory and University of Southern California. It is, however, missing several important high-level services. With the need to provi

Ekonomistyrning i Lund - Sveriges bästa skolkommun

Stora summor omsätts i skol- och barnomsorgen. År 2004 stod barnomsorgen för 13 % och skolan för 32 % av kommunerna bruttokostnader på 375 miljarder kronor (SKL, 2005). Tillsammans är verksamheterna de största kommunala kostnadsposterna, följt av vård och omsorg som förbrukar 40 % av bruttokostnaderna. Naturligtvis blir skolans ekonomistyrning viktig i ett sådant sammanhang. I denna artikel beskri

Identification of novel transcription factor-like gene from human intestinal cells

Intestinal crypt epithelial T84 cells form luminal structures and differentiate to intestinal enterocyte-like cells in response to IMR-90 fibroblast-secreted transforming growth factor-beta when grown within three-dimensional collagen gel. In search of TGF-beta regulated genes involved in this differentiation process, we isolated a TGF-beta downregulated cDNA, human homologue of rat apoptosis anta

Costs for screening, intervention and hospital treatment generated by the Malmö Preventive Project: a large-scale community screening programme.

OBJECTIVES: The purpose of this study was to estimate retrospectively the costs of health care resources used in the Malmö Preventive Project, Sweden and estimate the costs of in-patient care that were avoided because of early intervention. SETTING AND SUBJECTS: A large-scale community intervention programme was conducted from 1974 to 1992 in Malmö, Sweden with the aim of reducing morbidity and mo

Macrophage Activation and AP-1 in Atherosclerosis

High levels of very low density lipoprotein (VLDL) and intermediate density lipoprotein (IDL) have been identified as independent risk factors for coronary heart disease. Hypertriglyceridemia is generally associated with an increased expression of inflammatory makers and inflammation is thought to contribute to atherosclerosis and its complications. The present investigation was aimed at providing

Diffusion of a mixture of cations and anions dissolved in water

In service life modeling of concrete, the ion transport in the pore solution is crucial. The main deterioration phenomena associated with ions in the pore solution are (1) corrosion due to external chloride ions reaching the embedded reinforcement bars; (2) carbonation due to presence of dissolved carbon dioxide (which will form carbonic acid with water) supplied from the surrounding air; and (3)

Review of fungus gnats in the genus Tarnania Tuomikoksi, with a phylogeny of the Rymosia s.l. genus group (Diptera : Mycetophilidae)

The four known species of Tarnania Tuomikoski are reviewed, viz. T dziedzickii (Edwards, 1941), T. fenestralis (Meigen, 1818), T. nemoralis (Edwards, 1941), and T. tarnanii (Dziedzicki, 1910). Males and females are re-described, photographed and their terminalia figured. An attempt is made to homologize and name specific substructures of the male gonostylus, widely recognizable within the tribe Ex

Perceptual Surface Reconstruction

How does the brain transform the 2-D light arrays in our eyes into a meaningful 3-D description of surfaces around us? What assumptions does the visual system make about the world when information is incomplete? And how are these assumptions computationally expressed in this perceptual reconstruction process? These questions, and other aspects of binocular depth perception are analysed from a theo
