This paper presents and suggests a load combination factor for moisture induced stress (MIS) when MIS and snow load are combined. It is argued that MIS may be considered as an ordinary load to be combined with other structural actions, for example snow load. This outlook is not new but till now the load combination factor issue has not been investigated. Based on measured snow depths and calculate

Popular Abstract in English Nowadays road, air and sea transport activities around the world are almost completely dependent on finite and polluting oil fuels. Biofuels are fuels produced from biomass which can be used to substitute gasoline and diesel in cars, busses and (soon) planes. Where oil was created millions of years ago and is soon reaching its limit, biofuels are renewable fuels which cThe dependency of transport on oil fuels is responsible for risks of energy supply security, and local, regional and global environmental problems, including the emission of greenhouse gases affecting the Earth’s climate system. Biofuels attracted considerable attention in recent years as a solution to these problems. However, the deployment of biofuel technologies poses as many opportunities to b
Power systems are a vital infrastructure for the functioning of the society, generally regarded as one of the most critical infrastructures. Past power system blackouts (e.g., the Canadian ice-storm and New-Zeeland Power outage in 1998, the U.S. blackout in 2003, the European blackout in 2006 and the Indian blackout in 2012) have revealed the inherent vulnerabilities of power systems as well as th
Little is known the evolution of ‘yes’ and ‘no’ in human language, and in this paper, an attempt is made to make a first step in revealing how our ancestor came up with these words. Our analysis starts with Proto-Uralic, and then we compare its developmental path to other languages in the Indo-European family.
It has been documented that in Proto-Uralic (ca. 4,000 BC) there existed e ‘no’, but
This paper deals with policy options for constructing cross-border innovation systems. Trans-frontier cooperation and policies to stimulate increased interaction between neighbouring regions that belong to different nation states are not new phenomena. There is a large body of work on the governance structures of such areas and the array of public policies geared towards promoting increased econom
Popular Abstract in SwedishMänniskor spenderar en stor del av sin vakna tid åt att tänka på saker som är orelaterade till den uppgift de håller på med eller den omgivning de befinner sig i (dagdrömmar). Under tiden man jobbar, läser en tidning, eller väntar på bussen kan manexempelvis börja tänka på något trevligt man ska göra nästa helg eller en tidigare deprimerande händelse som upprör en. DagdrMany individuals spend a substantial portion of their waking time thinking about topics unrelated to current activities and surroundings (mind wandering). This dissertation sought to contribute to our knowledge of why some people mind wander more than others. Mind wandering in cognitive tasks is more common in individuals with poor executive cognitive control (working memory updating, inhibiting t
