is a Bio analytical technique that produces spectra (singular spectrum) of the lots of the atoms or molecules comprising a sample of fabric. The spectra determine the isotopic signature or elemental of a sample. Mass spectrometry
are those considered to be highly influential in their respective fields. The impact factor
of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals
of similar kind. It reflects the average number of citations to recent articles
published in science and social science journals
in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor
of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
