A hypothesis on the mechanism of ''salt-scaling'' of porous building materials is described. The hypothesis is based on theories on frost heaving in soils and observations made on micro ice-lens growth in cement paste specimens. The main principle is that ice crystals close to the surface are able to feed from the remaining liquid phase of the outer salt solution after freezing has begun. Though t

Abstract in Undetermined In this paper, we introduce robust versions of the recently introduced Capon- and APES-based Magnitude Square Coherence (MSC) spectral estimators. The estimators exploit the related recent development on robust beamforming to allow for imperfect knowledge of the estimated sample correlation matrix. The resulting estimators are found to yield improved estimates as compared

The objectives of Food4Me work package 5 included a baseline assessment of the ethical and legal aspects of personalised nutrition at the start of the project in 2011, as well as a final assessment at the end of the project (2015), taking into account results achieved in other work packages. The initial assessment made a number of ethical issues visible, most of them relating to the consumer of pe

Five students of a rescue training school cycled at 50 W for 20 minutes at 20 °C before walking up to 30 minutes in a climatic chamber at 55 °C and 30 % relative humidity. Four different types of clothing ensembles were used differing in terms of thickness and thermal insulation value were tested on separate days. All subjects completed 28-30 minutes in light clothing, but quitted after 20-27 minu

Anthropogenic radionuclide concentrations have been determined in seawater and sediment samples collected in 1991, 1994 and 1996 in the Eurasian Arctic shelf and interior. Global fallout, releases from European reprocessing plants and the Chernobyl accident are identified as the three main sources. From measurements in the Eurasian shelf seas it is concluded that the total input of Cs-134, Cs-137

The production of heavy salted cod (bacalao) has changed from being a single-step process salting to a multistep procedure. The aim of this study was to gain a deeper understanding of water retention and yields of heavy salted cod as influenced by salting procedures. The effects of different pre-salting methods (injection and brining, brining only, and pickling) were compared to a single kench sal

An analysis of Swedish-Spanish Gothicism and the impacts of these ideas

There is a continuing tendency to apply many of the powerful results of modern control theory to various industrial processes. Power systems have been indicated as one area where significant progress can be expected. Practically all results of modern control theory require that models of the processes in terms of state equations are available. The need to obtain such models has been a strong motiv

The question is asked because it is often thought that real humility (low opinion of oneself, not self-assertive) cannot exist together with a messianic consciousness. Jesus made large claims for himself and the importance of his actions and teaching, seeing himself as endowed with unique closeness to the Father in heaven and therefore religious authority, but did not strive for ordinary social po

Popular Abstract in Swedish Samhällets produktion av avfall är ett ständigt pågående problem. Tidigare metodik för att ta hand om avfallet genom att deponera det på soptippar håller på att förändras. Genom beslut inom EU har det kommit krav på sortering av avfallet vilket har lett till att hushållsavfall inte längre kommer att få deponeras. Ett sätt att ta hand om avfall är att förbränna avfallet Baling of MSW has been extensively used in Sweden and other countries for the storage of energy (biomass for energy) for incineration and production of either and or electricity and heat. Baling is performed in two principally different ways, leading to cylindrical- or rectangular bales. This work has focused on various parameters during the storage of MSW. The first parameters investigated were g

In this paper we investigate the impact of a decrease in trade costs on firm decisions to export. The main contribution of this paper is to evaluate empirically the theoretical predictions of several models of multi-product exporters. The focus is on the firm export entry decision and the within firm adjustment regarding product scope and intensity. For identification, a quasi-natural experiment,

How does costly communication affect organizational coordination? This paper develops a model of costly communication based on the weakest-link game and boundedly rational agents. Solving for the stochastically stable states, we find that communication increases the possibilities for efficient coordination compared to a setting where agents cannot communicate. But as agents face a trade-off betwee

Popular Abstract in Swedish Vilket lands domstolar är behöriga att lösa tvister som kan uppkomma till följd av elektroniska avtal där parterna hör hemma i olika länder? Vilket lands lag skall domstolen använda? Även om en svensk domstol är behörig är det inte säkert att den skall använda svensk lag. Dessa frågor sorterar inom ett ämnesområde som heter interationell privat- och processrätt. I avhanThis study addresses some of the private international law perspectives on electronic commerce, namely the matters of jurisdiction and choice of law. Electronic commerce is based on the formation of contracts, and when there are contracts, questions regarding legal issues arise. A distinctive trait of electronic business is that its activities are not bound by geographic borders in a traditional s
