    Notes: Summary. Variation in Lateglacial lithic assemblages has led some researchers to sub-divide the British Later Upper Palaeolithic into two or more typologically distinct phases (Campbell 1977; Jacobi 1988). Until now, however, the chronological relationships between the different phases have been difficult to demonstrate. In this paper we present new dating evidence for two distinct blade technologies of Lateglacial type found in southwest Britain. The first corresponds to the ‘Creswellian’(as defined by Jacobi 1991; Jacobi and Roberts 1992), and is dated to the earlier part of the Lateglacial Interstadial (c. 13–12,000 years BP); the second technology compares with European Federmessergruppen assemblages (literally, ‘penknife group’ industries, as described in Schwabedissen 1954) of the ‘forested’ phase of the Interstadial (c. 12–11,000 years BP). In addition to presenting the new dates, this paper explores the implications of treating the technologies as separate entities and puts forward preliminary ideas on differences in raw material use and other human subsistence behaviour.

    Comparative assessment of techniques for estimation of glomerular filtration rate with 99mTc-DTPA (1985)
    Springer

    Keywords: Glomerular filtration rate ; 99mTc-DTPA clearance

    Notes: Abstract The relative accuracy of five simplified methods of measuring glomerular filtration rate was prospectively assessed using 99mTc-DTPA. The slope of the biological clearance curve, the 3-h volume of dilution and three renal tracer uptake methods (Piepsz, Gates and Nielsen) were concurrently compared with a multiple blood sampling reference method. The volume of dilution method from a single blood sample was markedly superior to the other four simplified methods which all had a similar degree of accuracy.

    Effects of amperozide, 8-OH-DPAT, and FG 5974 on operant responding for ethanol (1998)

    Notes: Abstract  Both 5-HT1A and 5-HT2A receptors have been implicated in modulating ethanol self-administration. A novel serotonergic compound, FG 5974, with combined 5-HT1A agonist/5-HT2A antagonist activities, has shown effects in decreasing ethanol consumption in two-bottle choice paradigms. In the present study, the effect of this compound on operant responding for ethanol (as well as water and a saccharin solution) was compared to compounds possessing the separate neuropharmacological effects of this drug (the 5-HT1A agonist, 8- OH-DPAT, and the 5-HT2A antagonist, amperozide). While all three serotonergic compounds decreased operant responding for ethanol, only FG 5974 had no effect on water and saccharin responding. These results suggest that combined 5HT1A agonist/5-HT2A antagonist activity provides a more selective effect on ethanol reinforcement than either neuropharmacological action alone. Therefore, further analysis of mixed serotonergic compounds in general, and FG 5974 in particular, is warranted as they offer potential treatments for alcoholism.

    Corticosterone increases severity of acute withdrawal from ethanol, pentobarbital, and diazepam in mice (1994)
    Springer

    ISSN: 1432-2072
    Keywords: Substance withdrawal syndrome ; Corticosterone ; Ethanol ; Pentobarbital ; Diazepam ; Mice

    Topics: Medicine
    Notes: Abstract It has been suggested that withdrawal from several subclasses of central nervous system (CNS) depressants involves common underlying mechanisms. For example, mice genetically selected for severe ethanol withdrawal convulsions (Withdrawal Seizure Prone or WSP) have also been found to express severe withdrawal following treatment with barbiturates and benzodiazepines. Corticosteroids appear to modulate severity of withdrawal from CNS depressants. Therefore, it was hypothesized that corticosterone would enhance withdrawal convulsions following acute ethanol, pentobarbital, and diazepam in WSP mice. Corticosterone (20 mg/kg) administered following each of these drugs significantly increased severity of handling-induced convulsions during withdrawal. Corticosterone did not affect pre-withdrawal convulsion scores or handling-induced convulsions of drug-naive mice. These results suggest that withdrawal convulsions following acute ethanol, pentobarbital, and diazepam are sensitive to modulation by corticosterone and they support the hypothesis that stress may increase drug withdrawal severity.

    Catalytic properties of SrSn1−xSbxO3 in methanol oxidation (1996)

    Topics: Chemistry and Pharmacology
    Notes: Abstract Ceramic model catalyst materials of general formula SrSn1−x Sb x O3 are synthesised by solid state reaction. X-ray diffraction shows the materials to be single phase over the composition range 0 ⩽x⩽0.085, with a second phase, identified as SrSb2O5, being produced at higher antimony doping levels. XPS, Auger electron spectroscopy and valence band photoemission show strong segregation of Sb to the surface of the material even within the single phase regime. The catalytic properties of the materials are examined using methanol oxidation as a test reaction. The activity and selectivity to formaldehyde production shown by these materials is found to be strongly correlated with the attainment of the bulk solubility limit of Sb in the SrSnO3 perovskite host.

    Notes: Abstract The subcentre invariant manifold of elasticity in a thin rod may be used to give a rigorous and appealing approach to deriving one-dimensional beam theories. Here I investigate the analytically simple case of the deformations of a perfectly uniform circular rod. Many, traditionally separate, conventional approximations are derived from within this one approach. Furthermore, I show that beam theories are convergent, at least for the circular rod, and obtain an accurate estimate of the limit of their validity. The approximate evolution equations derived by this invariant manifold approach are complete with appropriate initial conditions, forcing and, in at least one case, boundary conditions.

    Transient decay studies of photophysical process in aromatic polymers. I. Multiexponential fluorescence decays in copolymers of 1-vinylnaphthalene and methyl methacrylate (1980)

    Notes: The considerable potential of high resolution time-resolved spectroscopic data for copolymer systems in elucidation of the intramolecular photophysical processes which occur in polymer systems is illustrated. Such information can not be gleaned solely from studies of homopolymers. Kinetic data and time resolved fluorescence spectra of copolymers of 1-vinylnaphthalene and methyl methacrylate indicate that conventional kinetic schemes are inappropriate for the discription of excimer formation in 1-vinylnaphthalene polymers. Evidence is presented for the presence of an emitting species in addition to the expected monomeric and excimeric forms. The nature of this third species is discussed and photophysical kinetic schemes are proposed to describe intramolecular excimer formation in such systems. Kinetic data have been derived for the principle deactivation pathways through investigation of the observed fluorescence decays upon the intrachain concentration of aromatic species.
