Temperaturen i ett material styrs av variationer i den omgivande miljön. Solstrålning, vindhastighet, lufttemperatur och långvågig värmestrålning bidrar tillsammas till att temperaturen i konstruktioner ändras i både tid och rum. Temperaturfördelningen i en konstruktion kan delas upp i komponenter; medeltemperatur, linjär temperaturdifferens horisontellt och vertikalt, samt en ickelinjär komponent

An area of considerable interest in second language (L2) acquisition is the difficulties learners face with the acquisition of articles. This article examines the role of prosody in the acquisition of articles by an endstate L2 English speaker focusing on the free morphemes the and a. In order to analyse the articles produced by a Turkish speaker named SD, we used the Praat (Boersma and Weenink, 2

Modelling the temperature dynamics of a district heating system is typically validated for a single pipe or a system with limited information about dynamic consumer behaviour. In the present work, time dependent consumer data from the Naestved district heating system was used to investigate the ability of modelling tools to represent the temperature profile distortion throughout an entire heating

PURPOSE: To prospectively evaluate the usefulness of magnetic resonance (MR) imaging for estimating pulmonary blood volume (PBV) and the variation in PBV throughout the cardiac cycle in experimental heart failure. MATERIALS AND METHODS: The animal care committee approved this prospective study. Seven pigs were studied before and after myocardial infarction. PBV measurement was validated in a phant

OBJECTIVE: To investigate if placental Doppler velocimetry can predict the recurrence of a small-for-gestational age (SGA) fetus in subsequent pregnancies. DESIGN: Retrospective study. SETTING: City cohort over 15 years attending a university hospital. METHODS: A total of 196 pregnancies suspected of a SGA fetus (

The existence of a uniform phase at the alveolar surface is demonstrated by polarizing microscopy and cryogenic transmission electron microscopy (cryo-TEM). Rabbit lungs were opened and the alveolar surface film was directly deposited on optical microscope coverslips and on electron microscope grids. In the polarizing microscope, the alveolar surface material deposited exhibits a uniform birefring

Foreign investors in the Nordic countries are most likely to find country risk arising from problems on the supply side, as in corporate structural changes. Such changes manifest themselves in a tendency toward concentration and internationalization on the macroeconomic level. Country risk can be divided into political risk and the risk of suspended payments, both of which are directly related to

Background: To date, no attempt has been made to systematically determine the apportionment of the hepatocellular carcinoma burden in Europe or North America among established risk factors.MethodsUsing data collected from 1992 to 2006, which included 4 409 809 person-years in the European Prospective Investigation into Cancer and nutrition (EPIC), we identified 125 case patients with hepatocellula
