A recently published paper [T. Došlić, this journal 3 (2012) 25-34] considers the Zagreb indices of benzenoid systems, and points out their low discriminativity. We show that analogous results hold for a variety of vertex-degree-based molecular structure descriptors that are being studied in contemporary mathematical chemistry. We also show that these results are straightforwardly obtained by u...

three nearly simultaneous events around the end of the 19th century, i.e., the discovery of x‐rays by roentgen in 1895, natural radioactivity by antoine‐henri becquerel in 1896 and isolation of radium by the curies' in 1898 opened the nuclear era which has changed broadly the worlds of physics, biology and medicine. at the close of the 20th century, fundamental discoveries in biology at mo...

introduction: citation tracking is a bibliometrics method to analyze the scientific impact of journal articles which can be done through scopus (sc), google scholar (gs), or isi web of knowledge (wos). in the current study, we analyzed the citations to 2006-2012 articles of iranian journal of nuclear medicine (ijnm) in the sc and gs. methods: we retrieved the relevant data from sc and gs offici...

the recently published articles in the iranian journal ofbiotechnology inspired us to write this short communication on nitrogen dioxide no2-philic plants (1).to cope with environmental pollution, we thought(still think) that development of methods that mitigatepollution is an urgent issue, and that no2-philic plantsthat can grow with no2 as the sole nitrogen source areinstrumental for the impl...
