In response to the increased early workflow implied by BIM processes it is important for design consultants to focus on creating and communicating information that is critical for its purpose (Jernigan 2008) - be it model content for 3d Design Coordination at scheme design stage, or Cost Estimation at Design Development stage, or generation of a suitable Record Model for Facilities Management. Tod

Yersinios och shigellos är två bakterieburna och livsmedelsrelaterade sjukdomar som medför betydande kostnader i termer av direkta kostnader (kostnader för vård, medicin, rehabilitering etc.), indirekta kostnader (produktionsbortfall till följd av sjukfrånvaro) och immateriella kostnader (obehag, illamående och dylika immateriella aspekter som kan kopplas till sjukdomen). Det är väsentligt att upp

Utbildning i hållfasthetslära är självklar för den som bygger konstruktioner som ska hålla i åratal. Lika självklart borde det vara med hållfasthetslära för människor som ska hålla i åratal. Att människor saknar kunskap om mänsklig hållfasthet visas tydligt i antalet långtidssjukskrivningar för utmattningssyndrom. Människor som saknar en god självkänsla bygger sitt hus på en instabil grund. När de

The problem of spontaneous cutting tool failure, such as tool chipping and breakage, is becoming more and more important in the manufacturing technology. The sponataneous tool failure is usually associated with the stresses subjected on the tool during a metal cutting process. When the maximum stress acting in a cutting tool exceeds its critical stress, which is usually determined by tool geometry

Popular Abstract in Swedish Alla levande organismer behöver kväve för att producera till exempel proteiner och DNA. I jorden förekommer kväve grovt indelat i två huvudformer, organiskt och oorganiskt. Mikroorganismer har förmågan att bryta ner det organiska kvävet till oorganiskt i en process som kallas för mineralisering. Växter tar i stort sett bara upp oorganiskt kväve och är beroende av den miMicroorganisms in forest ecosystems normally recycle nitrogen (N), such that gaseous losses and leaching are limited. Mobilization of organic N, including microbial N, and immobilization of inorganic N, especially NH4+, are the quantitatively most important N transformation processes. Various factors influence their rates, e.g. the amount of carbon and nitrogen, temperature, moisture, and the micr

In this study we investigate to what extent computer based discrete event simulation modeling can contribute to students’ learning processes in logistics and production management courses. Our interest in simulation stems from the fact that it is not possible to let students experiment with real logistics and production systems. This is an issue because the complexity and stochastic nature of thes

The resistivity method is an established geophysical method with a broad range of engineering and environmental applications. It has been tried numerous times on embankment dams, mainly for seepage investigations, dam status control and investigations of known defects. In previous use of the method on embankment dams some success has been reported, but only occasionally. The method is still not co

An overview of recent nuclear structure studies in the vicinity of the doubly-magic isotope Ni-56 is presented. Detailed spectroscopy of mirror nuclei, 'complete' high-spin spectroscopy, the gamma-decay out from superdeformed rotational structures, and prompt particle emission are some of the topics in the mass A similar to 60 regime which challenge the power of the 'big arrays'.

This paper presents a comparison of the thermal properties between infiltrated and non-infiltrated copper windings. The focus is on thermal conductivity in the radial direction on the winding. The samples have a fill factor above 65 % due to the manufacturing method of the samples. Samples are produced and measured with the transient plane source technique and then compared to FEM simulations and
