Metric Options: Counts1 Year3 YearSelecting 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
In this study, conventional solar still was modified by adding variable slope tilted wick in the basin so that day and night productivity of still can be enhanced. The tilted wick was constructed in such a way so that tilt angle can vary according to the incident angle of solar radiation i.e. from 0° to 45°. The experiments were conducted under similar weather conditions for several days. The depth of basin water of still was taken 3 cm for all set of experiments. Initially, the experiments were conducted on 30° tilted wick with different flow rate (0.10 g/m 2 /s, 0.20 g/m 2 /s, 0.30 g/m 2 /s) on the wick inside the basin of modified solar still. The range of flow rate was taken based on trial experiments so that wick don’t get dry throughout the day. The overall distillate of modified still with 30° tilted wick at 0.10 g/m 2 /s, 0.20 g/m 2 /s and 0.30 g/m 2 /s flow rate was found to be 3.51 kg/m 2, 3.60 kg/m 2 and 3.41 kg/m 2 respectively. Further, the experiments with tilted wick were conducted at 0.20 g/m 2 /s flow rate and 3 cm water depth in the basin by varying angle of inclination of tilted wick at 0°, 15°, 30° and 45°. It have observed that the overall distillate at 0°, 15°, 30° and 45° angle of tilt of wick was found to be 3.1 kg/m 2, 3.51 kg/m 2, 3.60 kg/m 2 and 3.41 kg/m 2 respectively. The maximum distillate was observed at 30° which is almost equivalent to the latitude of the location and sunrays falls directly on the wick surface. It has been found that day and night distillate of modified still with 30° remains 37.17 % higher than that of conventional still. The maximum cumulative efficiency was found to be 43.16% for the modified still with tilted wick at 30°.
