摘要:Abstract(#br)Using data from 214 hydropower projects in Norway we study whether investors in renewable energy projects exert discretion about the timing of investment decisions. We know from interviews with these investors that they do not use the real options model; however, we ...

摘要:Abstract(#br)In this study we aimed to investigate the effects on historical NO x estimates on time trends, spatial distributions, exposure contrasts, the effect of relocation patterns and the effects of back extrapolation. Historical levels of nitrogen oxides (NO x ) from 1...

摘要:Abstract(#br)Attractiveness of magnesium alloys for structural applications is caused by their intrinsic properties i.e. low density and high specific strength. The main challenge in development of magnesium alloys is connected with requirement to fulfill the main function o...

摘要:Abstract(#br)Grain boundary plane distribution is analyzed for the Σ 13 coincident site lattice grain boundaries in magnesium. These boundaries are relatively frequent in materials with hexagonal structure. It was shown that the most frequent boundary plane is (0 0 0 1) basa...

摘要:Abstract(#br)The contribution of long-range transported (LRT) to urban background PM 10 concentrations was investigated from a long-term view from 1986 to 2010. Regional air concentrations of sulphate (SO 4 2− ), nitrate (NO 3 − ), and ammonium (NH 4 + ) were used as a sum (...

摘要:Abstract(#br)Background and aims(#br)Exposure to air pollution has been linked to total and cardiopulmonary mortality. However, few studies have examined the effects of exposure over decades, or which time windows of long term exposure are most relevant. We investigated the ...

摘要:Grain refinement of magnesium alloys at temperatures below 200 °C via deformation processes is a challenging task. Equal channel angular pressing is one of the severe plastic deformation techniques which can significantly refine grain size. Refined grains consequently improv...

摘要:The nucleation of { 1 0 1 ¯ 2 } twins at grain boundaries was studied in an Mg–3 wt.% Al–1 wt.% Zn alloy processed by equal channel angular pressing at 200 °C. A larger fr...

摘要:Abstract(#br)We study the impact of fuel prices, emission allowances, demand, past prices, wind and solar production on hourly day-ahead electricity prices in Germany over the period from January 2015 until June 2018. Working within a linear regression, ARX-EGARCH and quantile re...
