Since the nuclear accident in Fukushima the European electricity economy has been in transition. The ongoing shut down of nuclear power plants and the widespread installation of wind power and photovoltaic generation capacities, especially in Germany, has led to a high share of intermittent renewable electricity production. This high amount of generation with very little variable cost has led t...
The essential oils obtained by hydrodistillation (HD), steam distillation (SD) and solvent free microwave extraction (SFME) from the stems and flowers of Tanacetum tenuisectum (Boiss.) Podl., which is endemic to Iran,were analyzed by GC and GC/MS.Camphor (26.9 %, 27.2% and 25.5%), borneol (12.6%, 11.5% and 7.6%) and 1, 8-cineole (7.9%, 13.2% and 11.3%) were the main constituents of the HD, SD a...

Extended abstract 1- INTRODUCTION In the arid and semi-arid areas of Asia, dust storms occur frequently. Much progress has been made in the monitoring modeling and prediction of Asian dust storms. Dust emission is caused by wind erosion in the sensitive areas. Wind erosion is described as the transportation of soil particles by means of the wind. Soil Surface moisture is one of the most i...
The authors characterize impacts on heat in the ocean climate system from transient ocean mesoscale eddies. Their tool is a suite of centennial-scale 1990 radiatively forced numerical climate simulations from three GFDL coupledmodels comprising the ClimateModel, version 2.0–Ocean (CM2-O), model suite. CM2-O models differ in their ocean resolution: CM2.6 uses a 0.18 ocean grid, CM2.5 uses an int...

In this paper we assess the semantic stability of Wikipedia by investigating the dynamics of Wikipedia articles’ revisions over time. In a semantically stable system, articles are infrequently edited, whereas in unstable systems, article content changes more frequently. In other words, in a stable system, the Wikipedia community has reached consensus on the majority of articles. In our work, we...
A public debate exists whether the flow of consumer information should be restricted, and whether privacy laws — such as the Gramm-Leach-Bliley Act for financial institutions — should be amended. We offer a welfare comparison of the three main current policies towards consumer privacy — anonymity, opt in, and opt out — within a two-period address model. These privacy policies shape a firm’s abi...
