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
Harmful Algal Blooms (HABs) are an increasing concern not only in Nebraska, but across the world. Increasing global temperatures in conjunction with overuse of synthetic fertilizers are leading causes to the increasing frequency and concern of HABs. In the present work, the effectiveness of simulated bank filtration (BF), as an economical water treatment option, to remove cyanotoxins under different levels of nutrients (nitrates and phosphates) was investigated. Vertical flow-through columns pre-acclimated with two levels of nutrients (e.g., nitrate and phosphate—10 vs. 50 mg/L) were exposed to two different levels of cyanotoxins (10 vs. 75 μg/L). Results from the study confirmed the ability of simulated BF to remove cyanotoxins. High cyanotoxins removals (>70%) were achieved regardless of the levels of nutrients and cyanotoxins. It can be recommended to guarantee enough travel time (>7 d) to enhance the removal of cyanotoxins. The majority (42 – 60%) of the overall removal occurred within the top 10 cm of the column, thus representing the effect of biodegradation. An additional 6% - 35% cyanotoxin removal occurred within the remaining 150 cm, thus representing the physicochemical processes within the packing material. Among the removal mechanisms, biodegradation was the predominant removal mechanism.Advisor: Chittaranjan Ray
