The values of GWQI of water samples during dry and wet seasons were found in the range of 16.8-38.4 and 11.4-48.9, respectively. About 50% of sampling waters belong to “Excellent” water status and 50% under “Good” class during dry season. During wet season, 70% of sampling points come under “Excellent” water status while 30% belongs to “Good” water status. The GWQI value of each well for both seasons revealed their fitness for drinking and human consumption purposes. Pearson’s correlation coefficients among selected water quality parameters show very strong association between EC and TDS in both seasons.]]> https://scialert.net/abstract/?doi=rjp.2015.1.10 10 June, 2026 Validity of High Pressure Isothermal Equation of State for Carbon Nanotubes https://scialert.net/abstract/?doi=rjp.2015.11.20 10 June, 2026 On the Drying Efficiency of Potato Chips Using Open Sun Drying and a Locally Fabricated Solar Dryer –1 and 68.5%, indicating the potentials and effectiveness of the constructed solar dryer compared to the OSD method.]]> https://scialert.net/abstract/?doi=rjp.2015.21.29 10 June, 2026
