Dynamic rating is an approach which implies to operate electrical network closer its thermal limits. This may be very beneficial for wave farms, as they are expected present a highly fluctuating current profile while benefiting from the large inertia of soil where their export cable will buried. However, implementation this still in infancy offshore wind it that first under form small-scale tes...

When a substantial number of wind parks are approaching the end their lifespan, and developers renewables facing decisions about what to do with assets, concepts such as hybrid power plants emerging promising solution enable renewable integration in cost-effective robust manner. This work proposes decision-aid algorithm perform comprehensive analysis plants, focusing on energetic contribution e...

Abstract In the North Nile Delta of Egypt, impacts overplanting paddy rice on water delivery performance have not been discussed quantitatively. Further, amount that could saved if farmers would follow planned area is unknown. this study, was assessed by comparison actual planting and government’s conditions. For both conditions, indicators relating to adequacy, equity, dependability were analy...

To decarbonize electrical power systems, it is essential to incorporate a high share of variable renewable energy sources while minimizing their costs. An important step towards this goal includes exploring the potential for so-called hybrid plants through combination (existing) wind and solar parks. Although that not usual approach in design, should take advantage existing synergies, as genera...

To solve the problems posed in Doctrine to ensure food security of population Russia (2020), it is important increase productivity and quality voluminous fodder on meadow hayfields. In Federal Scientific Center "VIK named after V.R. Williams", improved technologies have been developed for creation use legume-grass stands (with participation four legume species) using presowing inoculation seeds...

The range of natural environmental degradation caused by anthropogenic activity may include geomorphological forms such as dunes resulting from the build-up wind. In effect, transformation affects changes connected not only with their relief, but also presence and health diverse plant animal inhabitants. subject survey was a parabolic dune asymmetric shape, sand which subjected to exploitation ...

Water shortage is a major constraint to sustaining and increasing the productivity of rice-wheat systems. Saving water can be elusive in that reducing seepage, percolation and runoff losses from fields does not necessarily save water if it can be recaptured at some other temporal or spatial scale, for example by groundwater pumping. Many technologies appear to save substantial amounts of water ...
