The damselfly genus Enallagma originated in the Nearctic, and two Nearctic lineages recently underwent radiations partly associated with multiple independent habitat shifts from lakes dominated by fish predators into lakes dominated by dragonfly predators. A previous molecular study of four Palearctic morphospecies and all representative Nearctic species identified the presence of two cryptic s...

ABSTRACT The outer light (stellar haloes) of massive galaxies has recently emerged as a possible low scatter tracer dark matter halo mass. To test the robustness measurements across different data sets, we compare 1D azimuthally averaged surface brightness profiles using four independent sets: Hyper Suprime-Cam survey (HSC), Dark Energy Camera Legacy Survey (DECaLS), Sloan Digital Sky (SDSS), a...

In the present scenario depletion of conventional sources causes an energy crisis. The crisis load demand with respect to electricity. use renewable plays a vital role in reducing and reduction CO2 emission. solar is major source power generation as this root cause for development wind, tides, etc. However, due climatic condition availability PV varies from time time. Hence it essential track m...

Abstract NASA’s Dragonfly mission will send a rotorcraft lander to the surface of Titan in mid-2030s. Dragonfly's science themes include investigation Titan’s prebiotic chemistry, habitability, and potential chemical biosignatures from both water-based “life as we know it” (as might occur interior mantle ocean, cryovolcanic flows, and/or impact melt deposits) “life, but not that use liquid hydr...
