The Lippia genus is used in ethnobotany as food, beverages, seasoning and antiseptic remedies, among others. The chemical compositions of fifteen extracts of six Lippia species were investigated comparatively by HPLC-PDA. To avoid data replication of previous works on this genus, Lippia lupulina Cham. root ethanol extract was selected for isolation procedures based on Principal Component Analys...

The fractional arboricity of a digraph D $D$ , denoted by γ ( ) $\gamma (D)$ is defined as = max H ⊆ | V > 1 A − (D)=\mathop{\max }\limits_{H\subseteq D,|V(H)|\gt 1}\frac{|A(H)|}{|V(H)|-1}$ . Frank proved that decomposes into k $k$ branchings, if and only Δ ≤ ${{\rm{\Delta }}}^{-}(D)\le k$ (D)\le In this paper, we study analogues for the Nine Dragon Tree Conjecture. We conjecture that, positive...

The kinetics of the membrane current during the anomalous or inward-going rectification of the K current in the egg cell membrane of the starfish Mediaster aequalis were analyzed by voltage clamp. The rectification has instantaneous and time-dependent components. The time-dependent increase in the K conductance for the negative voltage pulse as well as the decrease in the conductance for the po...
