Introduction: Groundwater is the main source of water supply for agricultural purposes, especially in arid and semi-arid regions. the Water Quality Index (WQI) is used to provide early and quick results of the assessment of water quality status, IRWQI has been developed with the aim of using appropriate method with natural conditions and water resources issues in Iran. In this research, the tre...
Through meticulous daily observation of the Sun’s large-scale magnetic field Wilcox Solar Observatory (WSO) has catalogued two (Hale) cycles solar activity. Those (∼22-year long) Hale have yielded four (∼11-year sunspot (numbers 21 through 24). Recent research highlighted persistence “Extended Cycle” (ESC) and its connection to fundamental Cycle–albeit a host proxies resulting from image analys...
