While rapid evolution in introduced ranges is a mechanism at later stages of the invasion process, the introduction of adapted genotypes is a key driver of naturalisation of populations of introduced species. 展开 关键词: Forestry provenance trials genotype‐by‐environment interactions intraspecific ...

where ΔΓis the energy difference between the gauche and trans conformations, ca. 500cal. The factor 2 is placed because there are three possible angles per bond. The entropy of mixing,i.e. the conformational entropy,Sc, for the trans and gauche conformations is obtained through an approximat...
BERLIN, April 21 (Xinhua) -- The number of electric vehicles (EVs) in operation in Germany has grown three times as fast over the past two years as the country's public charging infrastructure, the state-owned promotional bank KfW said on Thursday. "If this trend continues it could become...
f(x)=1x2+1 has a power-series expansion about x=0 that only converges for ∣x∣<1, and it may not be obvious why that is so. But now we know (from a complex-variable perspective) that the region of convergence is limited by the poles of f(z) at ±i, corresponding to a disk...
Cluster analysis is further applied and it generates three major driving forces profiles among the 30 metropolitans, with respect to the relative importance of different categories of determinants and their combinations. The driving force profiles should be useful for managers to set priorities in ...
T cells express transcription factors T-bet, GATA-3, RORγt and Foxp3, representing Th1, Th2, Th17 and Treg cells respectively. No study has directly determined the relative presence of each of these T cell subsets concomitantly in a model of allergic airway inflammation. In this study we ...
