Hydroelectric power, along spoken as hydropower, electricity product of generators driven by turbines that convert the energy of falling or fast-flowing water into energy. at intervals 1st} twenty initial century, electricity power was the foremost wide used fairly renewable energy; in 2019 it accounted for quite eighteen p.c of the world’s total power generation capability. at intervals the generation of electricity power, water is collected or hold on at consecutive elevation and diode downward through immense pipes or tunnels (penstocks) to a lower elevation; the excellence in these 2 elevations is believed as a results of the head. At the best of its passage down the pipes, the falling water causes turbines to rotate. The turbines successively drive generators, that convert the turbines’ energy into electricity. Transformers unit of mensuration then wont to convert the alternating voltage acceptable for the generators to consecutive voltage acceptable for long-distance transmission. The structure that homes the turbines and generators, and into that the pipes or penstocks feed, is termed the powerhouse.

To increase the visibility and ease of use of open access scientific and scholarly journals top online publishing journals are indexed in different indexing and archiving services. Indexing provides easy access of the article online. The top online publishing journals publish articles which are cited as references by many authors in their work. Citations are important for a journal to get impact factor. Impact factor is a measure reflecting the average number of citations to recent articles published in the journal. The impact of the journal is influenced by impact factor, the journals with high impact factor are considered more important than those with lower ones. Indexing provides easy access of the article online. The international journals are among the best open access journals in the world, set out to publish the most comprehensive, relevant and reliable information based on the current research and development on a variety of subjects. This information can be published in our peer reviewed journal with impact factors and are calculated using citations not only from research articles but also review articles (which tend to receive more citations), editorials, letters, meeting abstracts, short communications, and case reports. The inclusion of these publications provides the opportunity for editors and publishers to manipulate the ratio used to calculate the impact factor and try to increase their number rapidly. Impact factor plays a major role for the particular journal.
