Sexual selection on song and cuticular hydrocarbons in two distinct populations of Drosophila montana [PDF]

, 2011
Sexual selection has the potential to contribute to population divergence and speciation. Most studies of sexual selection in Drosophila have concentrated on a single signaling modality, usually either courtship song or cuticular hydrocarbons (CHCs ...

Effect of Cu(NO₃)₂ and Cu(CH₃COO)₂ Activating Additives on Combustion Characteristics of Anthracite and Its Semi-Coke

Energies, 2020
The process of anthracite and its semi-coke combustion in the presence of 5 wt.% (in terms of dry salt) additives of copper salts Cu(NO3)2 and Cu(CH3COO)2 was studied. The activating additives were introduced by an incipient wetness procedure.
