Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Posidonia oceanica (L.) is an endemic sea grass in the Mediterranean Sea. Its dead leaves are accumulated in the beaches. Biomass based on dead leaves of P. oceanica is considered as a beach waste. Therefore, they are burned to keep beaches clean. In the present study, an alternative eco-friendly evaluation approach for removal of methylene blue by dead leaves of P. oceanica is studied. Dynamic removal of methylene blue from aqueous solution is performed in a fixed-bed column. Effects of different flow rates and bed heights on column performance are investigated and best flow rate and bed height are observed at 7.28 mL/min and 9 cm, respectively. Column performance has been modeled with Thomas and Artificial Neural Network models. The results confirm that dead leaves of P. oceanica can be used as a fixed-bed material for the dynamic removal of dyes in the waste waters from textile industry.
