    In:  Supplement to: Jiang, Yan Wen; Wise, Sherwood W (1987): Paleocene-Eocene calcareous nannofossils of onshore wells from the Coastal Plain of New Jersey and Maryland, U.S.A. In: van Hinte, JE; Wise, SW Jr; et al. (eds.), Initial Reports of the Deep Sea Drilling Project, Washington (U.S. Govt. Printing Office), 93, 699-711, https://doi.org/10.2973/dsdp.proc.93.119.1987

    Description: Paleogene calcareous nannofossils from split spoon cores recovered from five wells along the Coastal Plain of New Jersey and Maryland have been analyzed in order to provide onshore information complementary to that derived from the offshore DSDP Site 605 (upper continental rise off New Jersey). Hiatuses are more numerous and of greater extent in the onshore sections, but the major ones correlate well with those noted in the offshore section. At one site at least (Leggett Well), sedimentation may well have been continuous across the Cretaceous/Tertiary boundary, as it is believed to have been at DSDP Site 605. These various correlations are discussed elsewhere in a companion paper (Olsson and Wise, this volume). Important differences in nannofossil assemblages are noted between the onshore (shelf paleoenvironment) and offshore (slope-rise paleoenvironment) sections. Lithostromation simplex, not present offshore, is consistently present onshore and seems to be confined to the Eocene shelf sediments of this region. The same relationship holds for the zonal marker, Rhabdosphaera gladius Locker. The Rhomboaster-Tribrachiatus plexus is more diverse and better preserved in the onshore sections, where the lowermost Eocene Zone CP9 is well represented. Differential preservation is postulated to account for two morphotypes of Tribrachiatus bramlettei (Brönnimann and Stradner). Type A is represented at DSDP Site 605 by individuals with short, stubby arms, but these forms are not present in the equivalent onshore sections. There they are replaced by the Type B morphotypes, which exhibit a similar basic construction but possess much longer, more delicate arms.

    Notes: Compound ceramic coatings with the main crystalline of Al2TiO5 (as-coated samples) wereprepared on Ti-6Al-4V alloy by pulsed bi-polar micro-plasma oxidation (MPO) in NaAlO2 solution. Thecoated samples were calcined in Ar and air at 1000oC, respectively. The phase composition, morphologyand element content of the coatings were investigated by XRD, SEM and XRF. The samples treated in Arand the as-coated ones were calcined in air at 1000oC to study the oxidation resistance of the samples. Theresults showed that Al2TiO5 decomposed and transformed into corundum and rutile TiO2 during the hightemperature calcination. Al2TiO5 decomposed very quickly in air and the proportion of Al2O3 to TiO2 was44:55 after a complete decomposition. On the contrary, Al2TiO5 decomposed very slowly in argon withthe final proportion of Al2O3 to TiO2 of 81:18 on the coating surface. The morphology of the ceramiccoatings after the calcination was also different. The coatings calcined in argon were fined: the grains andpores were smaller than those of the coatings calcined in air. The weight gains of both coatings changed inthe form of parabola law, and the weight gains of the coated samples treated in argon were comparativelylower than that of the as-coated samples. During the high temperature calcination, the samples treated inargon cannot distort easily, compared with the as-coated ones

    Notes: The anodized TiO2 ceramic film was post-treated by photoreduction and ion sputtering,respectively, to deposit platinum on the surface of the films. Surface morphology, the main elements ofthe films and platinum distribution on the film surface were investigated by scanning electron microscopyand energy dispersive spectroscopy. The phase composition of the films was examined by X-raydiffraction. The photocatalytic activity was compared through the effect of the films on photocatalytic(PC) degradation rate of the humic acid. The results showed that both films were composed of Pt5Ti3,rutile (R) TiO2 and anatase (A) TiO2, and the content of TiO2 (R) of the film prepared by photoreductionwas a little more than that of the film by ion sputtering. Compared with Pt on the Pt-TiO2 ceramic film byphotoreduction, Pt on the Pt-TiO2 film by ion sputtering dispersed more evenly and the grains were muchsmaller. Pt particulates in the film post-treated by ion sputtering were more strongly combined with thefilm than those by photoreduction. Besides, the PC degradation rate of humic acid by both Pt-TiO2 filmswere higher than that by TiO2 film, and Pt-TiO2 film by ion sputtering had higher catalytic activity andlonger using life than that by photoreduction

    Notes: In Pseudomonas aeruginosa, synthesis of the quorum-sensing signal molecules N-butanoyl-L-homoserine lactone (BHL) and N-hexanoyl-L-homoserine lactone (HHL) requires the LuxI homologue RhlI(VsmI). By using thin-layer chromatography in conjunction with high-performance liquid chromatography (HPLC) and mass spectrometry, we show that purified RhlI can catalyse the biosynthesis of BHL and HHL using either S-adenosylmethionine (SAM) or homoserine lactone (HSL) but not homoserine as the source of the homoserine lactone moiety. As we were unable to detect homoserine lactone in cytoplasmic extracts of Escherichia coli, we conclude that SAM is the natural substrate for RhlI-directed N-acylhomoserine lactone (AHL) biosynthesis. The N-acyl chain of BHL and HHL can be supplied by the appropriately charged coenzyme A derivative (either n-butanoyl-CoA or n-hexanoyl-CoA). The specificity of RhlI for charged CoA derivatives is demonstrated as RhlI was unable to generate AHLs detectable in our bioassays from acetyl-CoA, malonyl-CoA, n-octanoyl-CoA, n-decanoyl-CoA, DL-β-hydroxybutanoyl-CoA or crotonoyl-CoA. RhlI was also unable to use N-acetyl-S-3-oxobutanoylcysteamine, a chemical mimic for 3-oxobutanoyl-CoA. Furthermore, the RhlI-catalysed synthesis of BHL and HHL was most efficiently driven when NADPH was included in the reaction mixture.
