Comparison of EISCAT and ionosonde electron densities: application to a ground-based ionospheric segment of a space weather programme

Space weather Tennessee applications require real-time data and wide area observations from both ground- and space-based instrumentation.From space, the global navigation satellite system - GPS - is an important tool.From the ground the incoherent scatter (IS) radar technique permits a direct measurement up to the topside region, while ionosondes g

N(alpha)-acetyltransferase 40-mediated histone acetylation plays an important role in ecdysone regulation of metamorphosis in the red flour beetle, Tribolium castaneum

Abstract Histone acetylation, Word Art a crucial epigenetic modification, is governed by histone acetyltransferases (HATs), that regulate many biological processes.Functions of HATs in insects are not well understood.We identified 27 HATs and determined their functions using RNA interference (RNAi) in the model insect, Tribolium castaneum.Among HAT
