Diurnal Variation of Tear Film Dynamics During Digital Device Use
Abstract: With a primary focus on their effects on tear dynamics and ocular health, this research effort addresses the hyperlink between pre and post digital screen usage, time of day, and tear dynamics. The desired outcomes of the eye health metrics divulge that post-digital screen exposure significantly reduces mean tear production values across all conditions (p < 0.05), with this impact intensifying as the day progresses. These observations show the interplay …

Study of Diurnal Anisotropy Variation in Cosmic Ray Intensity During Minimum Solar Activity Period
Abstract: we present a comprehensive study of cosmic ray variations over the period from 1964 to 2018, encompassing solar cycles 20, 21, 22, 23, and 24. Both annual average and day-to-day variations have been analyzed to capture the temporal dynamics of cosmic ray intensity across multiple solar cycles. The study focuses particularly on periods of minimum solar activity, namely the years 1965, 1976, 1986, 1996, and 2008, when cosmic ray modulation …

Study on Single-Slope Solar Still for Experimental and Data-Driven Analysis for Improving Productivity with Different Basin Materials.
Abstract: This study investigates the single-slope solar still under the diurnal variation of water temperature and distillate yield under identical operating conditions. Experimental analysis was conducted to evaluate the performance enhancement through the incorporation of natural basin materials, namely hemp and sand. The water distillation process is focused on improving potable water productivity and thermal behaviour. The inclusion of hemp and sand in the basin leads to noticeable differences in productivity …

Seasonal Variation of VLF Radio wave Signal Strength at 19.8 KHz Received at Khatav India (16o46ʹN, 75o53ʹE)
Abstract: This research is a detailed study of the seasonal behavior of the VLF field strength of the waves transmitted by VLF station NWC Australia (19.8 kHz). This research was carried out by using the VLF Field Strength Monitoring System located at Khatav, India (16°46ʹN, 75°53ʹE) during the period of August 2009 to July 2010. This study explores how the ionosphere and VLF radio waves react to the solar radiation. In …
