Recycling wood ash from burnt wood (back to the forest grounds) is of great ecological importance. However, the ash cannot be recycled directly after combustion. There are several reasons for this, one being the volatility of wood ashes. Mixing ash/dolomite/water in order to obtain granular material is one method to stabilize wood ashes. The main problem is predicting the quantity of water to be a

The majority of the large hydro power plants in Sweden were built 1935 - 1975 and are located in a cold climate in the northern parts of Sweden. Since the power plants were designed for a service life of 50-100 years, some of them are soon to reach their estimated service life and some have already passed it. During a condition assessment to determine the status of the Porsi hydro power plant, con

Abstract in Undetermined I detta paper analyserar jag maskuliniteter i relation till den internationella humanitärättens (IHL) materiella innehåll som sådant samt i relation till ICRC:s tolkning och framställning av IHL i filmen ”International humanitarian law: A universal code”. Analysen utgår från Connells Masculinities, Pettmans Worlding Women, samt antar ett intersektionellt perspektiv i analy

Algorithmic issues for the two thermodynamically consistent viscoplastic formulations of Perzyna and Duvaut–Lions are discussed. It is shown that it is simple to avoid the numerical problems associated with a small relaxation time without resorting to elaborate perturbation techniques, as suggested in the literature. A systematic numerical investigation of the efficiency of Newton iterations, that

Abstract: This paper provides one of the first studies on the role of social media in shaping collective memory in contemporary China. Social media enable the ordinary to participate in creating, interacting, and distributing alternative narratives of the past. Therefore, collective memory has being reconfigured under the influence of social media. Nevertheless, previous collective memory studies

In this paper the spectral features of impulse noise in DSL systems are mapped from the waveform domain onto the symbol domain, considering a QAM receiver. This work can be viewed as part of a full symbol domain model for impulse noise, which should include the amplitude and spectral aspects. Since the available models of impulse noise in DSL are generally waveform-based, this kind of mapping is j

In this thesis we have performed a systematic atomic scale characterization of model catalysts under pressures ranging from UHV to atmospheric ambient. By using a unique approach, linking UHV and high pressures studies by combining traditional electron based techniques with novel high pressure in situ probes and ab initio calculations, the surface structure of the different model catalysts could b
