Hydroelectric reservoirs bury significant amounts of organic carbon (OC) in their sediments. Many reservoirs are characterized by high sedimentation rates, low oxygen concentrations in bottom water and a high share of terrestrially derived OC, and all of these factors have been linked to a high efficiency of OC burial. However, investigations of OC burial efficiency (OCBE, i.e., the ratio betwe...

Renewable energy facilities will constitute a major contribution to electrical power in the future. The wind turbine will, together with biomass, form the major renewables parts up to year 2030 including erection of offshore wind farms. The wind is a non-storable energy source, whose electric energy needs priming into interchangeable energy to be competitive for large-scale power generation. An...

The paper analyzes a structure of the energy industry in Siberia (the Siberian Federal District) though its comparison with Russian and world ones. We show how economic efficiency of large energy producers could change if we allowed for all the social and ecologic costs. We prove that the development of a nuclear power industry is necessarily advisable to be speed up in the territory of Siberia...

This paper describes a first version of a simulation model of the electrical energy system for the German federal state Bavaria in order to analyse its energy balance during the nuclear phaseout and the increase of renewable energy sources as well as energy storage capacities. According to current plans, in ten years 50 percent of the Bavarian electric power consumption should be covered by ren...

BACKGROUND Although leishmaniases are regarded as serious public health issues in the State of Tocantins, as consequence of the impact of environmental changes, small advances in taxonomic and ecological studies of Phlebotominae fauna are taking place in this state. The present study aimed to improve the knowledge about the sand flies, as well as about the aspects of the bioecology of leishmani...

We consider the challenging practical problem of optimizing the power production of a complex of hydroelectric power plants, which involves control over three continuous action variables, uncertainty in the amount of water inflows and a variety of constraints that need to be satisfied. We propose a policy-search-based approach coupled with predictive modelling to address this problem. This appr...
