Progress in the Knowledge, Application and Influence of Extremely Low Frequency Signals

Abstract

This paper describes the characteristics of contributions made by researchers worldwide in the field of ELF (extremely low frequency) waves from 1957 to 2019. The data were collected through the Scopus database and processed with analytical and bibliometric techniques. The selection of the keywords is an essential step, because ELF has a very different meaning in some areas of medicine, where it is associated with a gene. A total of 12,436 documents were worked on in 12 thematic communities according to their collaborative relationships between authors and documents. Studies included authors publishing in the different thematic areas and the country where the USA stands first with more researchers in this theme than China and Japan. Documents were analyzed from the temporal perspective, their overall contribution, means of publication, and the language of the publication. Research requires extra effort and multidisciplinary collaboration to improve the knowledge, the application, and influence of these fields.

Влияние Геомагнитной Бури На Низкочастотные Поля Линий Электропередачи

“…Электромагнитное загрязнение околоземного космического пространства излучением наземных ЛЭП будет и далее увеличиваться по мере промышленного развития общества [De Santis et al, 2015;Пилипенко и др., 2021]. Рост интенсивности PLE и PLHR уже начинает вызывать в мире беспокойство относительно риска для здоровья населения [García et al, 2020].…”

Advances in Solar Energy towards Efficient and Sustainable Energy

“…Within Europe, Italy is the country that contributes the most with 6.77% of the total, the largest contribution in Asia is made by China with 8.59% and in America the greatest contribution is made by the United States. The map shows that the African continent is where there is a greater concentration of countries that do not contribute with any researcher on this subject, as happens in other publications such as [7,8].…”

Measurement and Assessment of Exposure to 50 Hz Magnetic Fields from Common Home Electrical Appliances

“…Many research works and findings have shown significant association of electromagnetic fields exposure with behavioral changes [5], health problems and some diseases [6]- [9]. There is an increasing concern that exposure to EMF may be associated with biological and health effects such as Alzheimer disease [10], cancer and brain tumors [11]- [16], leukemia [14], [17]- [24], and other serious disorders [25].…”
