We present experimental evidence which confirms recently proposed ring current prediction methods for assigning hydrogen-bond proton nuclear magnetic resonance (NMR) spectra from tRNA (Robillard, G. T., Tarr, C. E., Vosman, F., & Berendsen, H. J. C. (1976) Nature (London) 262, 363-369; Robillard, G. T., Tarr, C. E., Vosman, F., & Sussman, J. L. (1977) Biophys. Chem. 6, 291-298). The evidence is...

Les dŽcouvertes de pŽtrole ou de gaz dans des conditions sŽvres de tempŽrature (plus de 150¡C) ou de pression (plus de 50 MPa) se comptent dans plusieurs bassins ˆ travers le monde. En mer du Nord, on prŽvoit de mettre en production des gisements dont les conditions de fond vont jusqu'ˆ 110 MPa et 190¡C. Ces caractŽristiques constituent un dŽfi pour la prŽdiction des propriŽtŽs des fluides de ...

Ditylenchus dipsaci showed an affinity, in relation to infection, for the temp at which it had been acclimated. The optimum infective temp was also correlated with field temp when collections were made during different seasons and from climatically different geographical areas. Nematode developmental stage did not influence infectivity.

I found some mistakes on Table 2 (page 1643) in my published paper in Materials [1]. A correct table is provided here. Table 2. The relationships between molecular structures of yellow anthraquinone dyes and their solubilities and dichroic ratios. Dye Solubility (wt %) 1) Dichroic ratio r. t. Low temp.

Th e at om i c force micro scopy in ultrahi gh vacuum and at low temp erature demonstrated its excellent capabil i ty to reach atomic resolution . N evertheless in the case of biologi cal samples high resolution has been achieved only in very few cases. W e demonstrated here the imp ortance of the appropriate choice of prob es and substrates in order to image DN A at low temp erature w ith high...

This research evaluated the influence of temporary cements (eugenol-containing [EC] or eugenol-free [EF]) on the tensile strength of Ni-Cr copings fixed with self-adhesive resin cement to the metal coronal substrate. Thirty-six temporary crowns were divided into 4 groups (n=9) according to the temporary cements: Provy, Dentsply (eugenol-containing), Temp Cem, Vigodent (eugenol-containing), Rely...

The negative impact of heat stress (HS) on the production performances in pig faming is of particular concern. Novel diagnostic methods are needed to predict the robustness of pigs to HS. Our study aimed to assess the reliability of blood metabolome to predict the sensitivity to chronic HS of 10 F1 (Large White × Creole) sire families (SF) reared in temperate (TEMP) and in tropical (TROP) regio...
