High Resolution XPS of the S2p core level region of the L-Cysteine/gold interface
No full textL-cysteine self-assembled monolayers (SAMs) have been deposited on gold from the liquid and vapour phase. Synchrotron based high resolution x-ray photoemission spectroscopy has been used to characterize the sulfur chemical states at the SAM/gold interface. Results obtained from pristine and x-ray irradiated samples, prepared with both as-received and purified L-cysteine, are reported. Pristine samples prepared with purified cysteine are characterized by an intense, largely dominant S 2p state at a binding energy around 162 eV (2p(3/2) level) assigned to thiolates. A second doublet around 161 eV develops during irradiation. By comparison with the literature, this doublet is assigned to atomic sulfur present either as impurity or generated by S-C bond scission. Comparative measurements performed, under similar experimental conditions, on pristine 3-mercaptopropionic acid [HS(CH2)(2)COOH] layers deposited from the liquid phase are also presented and discussed
Rattus fuscipes
No full textRattus fuscipes (Waterhouse, 1839). Zool. Voy. H.M.S. "Beagle," Mammalia, p. 66. TYPE LOCALITY: Neotype from Australia, Western Australia, Albany, "Little Grove" on Princess Royal Harbor, 4 mi S Mt Melville; holotype was lost (Mahoney and Richardson, 1988; Taylor and Horner, 1973). DISTRIBUTION: Coastal, subcoastal, and offshore islands of SW Western Australia; S coast from Eyre Peninsula in South Australia to W Victoria; coastal and subcoastal Victoria from Otway Peninsula north to near Rockhampton in Queensland; coastal Queensland from Townsville to Cooktown (see map in Taylor and Horner, 1973:15). SYNONYMS: assintilis, brazenori, coracius, glauerti, greyii, manicatus, mondraineus, murrayi, peccatus, pelori, ravus. COMMENTS: Taylor and Horner (1973) suggested, on morphological grounds, that the Queensland population of R. fuscipes (coracius) has a common ancestry with Queensland R. leucopus, a hypothesis reasserted by Taylor et al. (1982, 1983). This relationship, however, is not supported by either chromosomal (Dennis and Menzies, 1978) or biochemical data (Baverstock et al., 1983a, 1986). See Taylor and Calaby (1988a, Mammalian Species, 298).Published as part of Guy G. Musser & Michael D.

Australian Rattus
No full text130 p. : ill., maps ; 27 cm.Includes bibliographical references (p. 124-130)."The native Australian Rattus are represented by five species and 14 subspecies. The progenitor of these native Rattus appears to be an ancestral form of R. lutreolus which gave rise to two major lines. One line represents the forest species, R. fuscipes and R. leucopus, and of these, R. fuscipes appears to have given rise to R. leucopus through a R. f. coracius-like ancestor. The other major line is composed of the grassland species, R. sordidus and R. tunneyi. The link between these two is postulated as being through the two subspecies R. t. culmorum-R. s. sordidus. Rattus tunneyi tunneyi is the most distant subspecies from the R. lutreolus-type progenitor along this line, and R. leucopus cooktownensis is the most remote along the line of forest forms. Rattus exulans subspecies, which occurs within the political boundaries of Australia probably as a result of human biochore dispersal, is included in this study chiefly because it has been allied with native Rattus on occasion in previous investigations. We recognize four subspecies of Rattus fuscipes: R. f. fuscipes (synonyms = R. f. mondraineus and R. f. glauerti), R. f. greyii (synonyms = R. murrayi, R. greyii ravus, R. greyii peccatus, and R. greyii pelori), R. f. assimilis, and R. f. coracius (synonym = R. manicatus); two subspecies of Rattus leucopus: R. l. leucopus (synonym = R. l. mcilwraithi) and R. l. cooktownensis; three subspecies of Rattus lutreolus: R. l. lutreolus (synonyms = R. vellerosus, R. l. cambricus, and R. l. imbil), R. l. velutinus (synonym = ?Mus tasmaniensis), and R. l. lacus; three subspecies of Rattus sordidus: R. s. sordidus (synonyms = R. conatus and R. youngi), R. s. villosissimus (synonym = R. villosissimus profusus), and R. s. colletti; and two subspecies of R. tunneyi: R. t. tunneyi (synonyms = Mus woodwardi, R. melvilleus, and R. tunneyi dispar) and R. t. culmoram (synonyms = R. culmorum vallesius, R. culmorum austrinus, and R. culmorum apex)"--P. 5
