The pine sawfly Diprion jingyuanensis Xiao and Zhang (Hymenoptera: Diprionidae) is a serious pest of Pinus tabulaeformis Carr. in the Shanxi, Gansu, Inner Mongolia provinces P. R. China. sex pheromone D. was shown to be propionate ester 3,7-dimethyl-2-tridecanol. Virgin females contained an approximate 1:3 blend precursors erythro-(2S,3S,7R/S 2R,3R,7R/S)-3,7-dimethyl-2-tridecanol threo-(2S,3R,7...

Short Wavelength Laser Calculations in the Beryllium, Boron 2 and Carbon Isoelectronic Sequences Level populations of the 2s3p, 2s 3p 2 and 2s 2p3p configurations in ions of the Be I, R I and C I isoelectronic 2 sequences can be inverted with respect to populations of the 2s3s, 2s 3s 2 and 2s 2p3s configurations by electron collisional pumping. In the case of B I and C I ions, the process is an...

This paper intends to study the following degenerate fractional Schrödinger–Kirchhoff–Poisson equations with critical nonlinearity and electromagnetic fields in R3: {ε2sM([u]s,A2)(−Δ)Asu+V(x)u+ϕu=k(x)|u|r−2u+(Iμ∗|u|2s♯)|u|2s♯−2u,x∈R3,(−Δ)tϕ=u2,x∈R3, where ε>0 is a positive parameter, 3/4<s<1, 0<t<1, V an electric potential satisfying suitable assumptions, 0<k∗≤k(x)≤k∗, Iμ(x)=|x|3−μ 0<μ<3, 2s♯=3...

Although dielectric relaxation can significantly affect the intrinsic fluorescence properties of a protein, usually it is fast compared to fluorescence timescales and needs to be slowed down by adding viscogens or lowering temperature before its impact on fluorescence can be studied. We report here a remarkable blue shift in fluorescence upon bimolecular quenching in the single-tryptophan therm...

In this paper we investigate some basic properties of fractional powers. In this regard, we show that for any rational number 1 ≤ 2r+1 2s+1 < og(G), G 2r+1 2s+1 −→ H if and only if G −→ H− 2s+1 2r+1 . Also, for two rational numbers 2r+1 2s+1 < 2p+1 2q+1 and a non-bipartite graph G, we show that G 2r+1 2s+1 < G 2p+1 2q+1 . In the sequel, we introduce an equivalent definition for circular chromat...
