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
Many studies have been performed with the purpose of determining the effects of fines on paper properties. However, many of these studies fail to develop characterizations of the fines themselves before relating the presence of these fines to sheet properties. This study first developed complete characterizations of fines and then related the properties of the fines to properties of paper containing these fines.Bleached kraft, unbleached kraft, and TMP pulps from a southern pine were used in this project. Characterization of the fines included determination of physical features of the fines, size distribution, water retention value (WRV), drainability, and compressibility. Fines were then replaced in their respective pulp sources in levels from 0% to .30%. Handsheets were made and tested to determine various strength and optical properties.Results showed the bleached fines to be fibrillar, compressible, and hydrophilic. Presence of these fines promoted burst and tensile strength, while tear, opacity, and brightness suffered. Unbleached fines were a mix of flake-like and fibrillar material. These fines also promoted tensile and burst, while tear strength suffered. The TMP fines were comprised of chunky and flake-like material, and exhibited poor water holding and compressibility characteristics. Presence of these fines in a sheet promoted tensile and tear indexes, but decreased the scattering coefficient of the sheet.
