The increase of energy demand in the past 50 years and targets to reach net-zero carbon dioxide emissions have led an electricity production from renewable sources . This paper first gives a snapshot word's mix then reviews most widely used market; comparing their reliability, efficiency cost-effectiveness, highlighting major advantages weaknesses. review concludes that marine energy, specifica...

the north atlantic oscillation (nao) is one of the most prominent modes of low-frequency variability over the atlantic basin in the northern hemisphere. in the past decades, the impact of nao has attracted increasing scientific interest because the nao exerts an important impact on the regional climate and weather in the north atlantic region and adjacent continents. of particular interest is t...

We consider a burst of quadrupole gravitational radiation in the presence of a large static mass M situated at its source. Some of the radiation is back-scattered off the static field of the large mass, forming a wave tail. After the burst, the tail is a pure incoming wave, carrying energy back towards the source. We calculate this energy, and, in a numerical example , compare it with the outgo...

We summarize the theoretical description of wave packets on molecular energy levels. We review the various quantum mechanical effects which can be studied and the models that can be verified on this system. This justifies our claim that the wave packet constitutes a universal quantum object.
