However, while this was scientifically a success, [13] the experiment in practice produced less than 1% of the energy the facility used to create it: [14] while 3.15 MJ of energy was yielded from 2.05 MJ input, [15] the lasers delivering the 2.05 MJ of energy took about 300 MJ to produce in the facility.
In the author–date method (Harvard referencing), [4] the in-text citation is placed in parentheses after the sentence or part thereof that the citation supports. The citation includes the author's name, year of publication, and page number(s) when a specific part of the source is referred to (Smith 2008, p. 1) or (Smith 2008:1).

where characters is the number of letters and numbers, words is the number of spaces, and sentences is the number of sentences, which were counted manually by the typist when the above formula was developed. Non-integer scores are always rounded up to the nearest whole number, so a score of 10.1 or 10.6 would be converted to 11.
The law is derived from the principles of conservation of mass and momentum of the air stream flowing through an idealized "actuator disk" that extracts energy from the wind stream. According to Betz's law, no wind turbine of any mechanism can capture more than 16/27 (59.3%) of the kinetic energy in wind.
To a considerable extent the quality of work, in the absence of other criteria, is judged on the number of citations received, adjusting for the volume of work on the relevant topic. [citation needed] While this is not necessarily a reliable measure, counting citations is trivially easy; judging the merit of complex work can be very difficult.
In any given year, the CiteScore of a journal is the number of citations, received in that year and in previous three years, for documents published in the journal during the total period (four years), divided by the total number of published documents (articles, reviews, conference papers, book chapters, and data papers) in the journal during the same four-year period: [3]
