    Fundamentals of Structural Geology (2005)
    Cambridge University Press
    In:  Cambridge, Cambridge University Press, vol. 7, no. Publ. No. 12, pp. 127, (ISBN: 0521839270, 520 p.)
    Details
    Publication Date: 2005
    Description: Fundamentals of Structural Geology provides a new framework for the investigation of geological structures by integrating field mapping and mechanical analysis. Assuming a basic knowledge of physical geology, introductory calculus and physics, it emphasizes the observational data, modern mapping technology, principles of continuum mechanics, and the mathematical and computational skills, necessary to quantitatively map, describe, model, and explain deformation in Earth's lithosphere. By starting from the fundamental conservation laws of mass and momentum, the constitutive laws of material behavior, and the kinematic relationships for strain and rate of deformation, the authors demonstrate the relevance of solid and fluid mechanics to structural geology. This book offers a modern quantitative approach to structural geology for advanced students and researchers in structural geology and tectonics. It is supported by a website hosting images from the book, additional colour images, student exercises and MATLAB scripts. Solutions to the exercises are available to instructors

    Submersible observations on the daytime vertical distribution of Aequorea ?forskalea off the west coast of southern Africa (2005)
    Cambridge University Press
    In:  Journal of the Marine Biological Association of the United Kingdom, 85 (3). pp. 519-522.
    Details
    Publication Date: 2020-07-16
    Description: The vertical distribution of the hydromedusa Aequorea forskalea was investigated using observations from the research submersible 'Jago' collected during 36 dives off the west coast of southern Africa during November 1997 and April 1999. The mean population depth of Aequorea? forskalea deepened with increasing sea surface temperature. We suggest that this behaviour enables individuals to avoid offshore advection, to minimize spatial overlap with other large medusae and to maintain their position over the middle of the shelf.

    New furanoid and seco-labdanoid diterpenes from Leonurus persicus (1996)
    American Chemical Society
    In:  Journal of Natural Products, 59 (2). pp. 131-134.
    Details
    Publication Date: 2020-07-22
    Description: Six new labdane diterpenoids, leopersin C (1), 15-epi-leopersin C (2), leopersin D (3), leopersin E (4), leopersin F (5), and 7-epi-leopersin F (6) were isolated from the aerial parts of Leonurus persicus. Their structures were elucidated by extensive use of 1D and 2D homonuclear and heteronuclear shift-correlated 1H−13C-NMR spectroscopic methods. Leopersin C (1) and 15-epi-leopersin C (2) were obtained as a C-15 epimeric mixture, and their structures were elucidated on this basis.

    Automated In-Line Extraction of Uranium(VI) from Raffinate Streams with Online Detection by Cathodic Stripping Voltammetry (1995)
    American Chemical Society
    In:  Analytical Chemistry, 67 (21). pp. 3903-3910.
    Details
    Publication Date: 2014-02-04
    Description: An automated method for on-site monitoring of uranium(VI) in raffinate streams originating from nuclear fuel reprocessing plants is described. An in-line stripping procedure (based on liquid/liquid extraction) was developed to extract U(VI) from this stream, a solvent mixture of 20% tributyl phosphate and nitric acid in kerosene, into an aqueous sodium sulfate solution, Degradation products in the solvent mixture, especially dibutyl phosphate, give rise to very strong complexes and are responsible for moderate but constant U(VI) recoveries (similar to 50%), Optimal conditions for in-line stripping comprise a mixing ratio of extractant (0.5 M sodium sulfate in water)/solvent mixture of similar to 3 and a pumping rate of similar to 0.4 mL min(-1) of the solvent mixture. The determination of U(VI) was by on-line cathodic stripping voltammmetry (CSV), preceded by adsorptive collection of the U(VL) as an oxine complex onto a hanging mercury drop electrode, Quantities of 1-2 mL of the aqueous extract were pumped into the voltammmetric cell and diluted (1/5 to 1/10) with a background electrolyte containing 0.1 M PIPES buffer, 2 x 10(-4) M oxine, 10(-4) M EDTA, and 0.2 M hydrazine hydrate (pH 9.0), The CSV peak for U(VI) was obtained at -0.68 V with a detection limit of 20 nM in the raffinate stream using an adsorption time of 120 s, Both the inline stripping procedure and the on-line measurement were fully automated, with a relative standard deviation in the measurements of 〈 5%.

    Correlates of growth and feeding in laboratory-maintained Eledone cirrhosa (Cephalopoda: Octopoda) (1998)
    Cambridge University Press
    In:  Journal of the Marine Biological Association of the United Kingdom, 78 (3). pp. 919-932.
    Details
    Publication Date: 2021-05-05
    Description: Octopuses ( Eledone cirrhosa (Octopoda: Cephalopoda)) held in an aquarium were subjected to varying conditions of feeding and starvation to evaluate putative indices of feeding and growth. Specific growth rate (%d −1 ) was linearly related to feeding rate (% of the body mass d −1 ) in animals with a mean body mass of 250 g at 15°C. Maximum growth rates varied between 〉 2% d −1 (body weights 〈 300 g) to 〈 1% d −1 (body weights ≤ 900 g) but specific growth rates were not related to body weight. Growth rates became negative (weight loss) after one week without food. The digestive gland index (DGI) was significantly correlated with short and long-term feeding and specific growth rates, and with body weight. Muscle RNA concentration was linearly correlated with growth rate during the previous 1–3 weeks but not with feeding rate. RNA:protein ratios were not different between mid-arm and mantle sample sites but arm tip values were significantly higher. RNA:protein ratio was related to body weight only in feeding animals. It is concluded that DGI is an index of feeding rate and that RNA:protein ratio can be used as an index of recent (~ 4 weeks) growth rate.

    New Records of Cephalopods Caught in Irish and Scottish Waters (1997)
    Cambridge University Press
    In:  Journal of the Marine Biological Association of the United Kingdom, 77 (2). pp. 561-564.
    Details
    Publication Date: 2021-05-06
    Description: Records of unusual cephalopods, taken as by-catch in Irish and Scottish waters in the years 1985–1995, are presented. Of most interest are three specimens of giant squid (Architeuthis) that were caught in bottom trawls off the west of Ireland between April and June 1995, all were mature males of mantle length ∼1000 mm. Other records include a large mature female Histioteuthis bonnellii from the west of Ireland and three specimens of the gelatinous incirrate octopus, Haliphron atlanticus.

    An apparent lack of response by metazoan meiofauna to phytodetritus deposition in the bathyal northeast Atlantic (1996)
    Cambridge University Press
    In:  Journal of The Marine Biological Association of The United Kingdom, 76 (2). pp. 297-310.
    Details
    Publication Date: 2019-01-22
    Description: Metazoan meiofauna were studied in replicated multiple-corer samples obtained at a bathyal site (1320–1360 m depth) in the Porcupine Seabight (51°36′N 13°00′W) before (April) and after (July) the delivery to the seafloor of a phytodetrital pulse originating from the 1982 spring bloom. In all samples the metazoan meiofauna was dominated by nematodes; harpacticoid copepods and their nauplii were the second most abundant taxon. Population densities and biomass were very similar in both sample sets, the only significant differences being in the numbers of ostracods (higher in April) and nauplii (higher in July). Furthermore, vertical distribution patterns in the top 5 cm of sediment indicate that the meiofauna did not migrate towards the sediment surface following the phytodetrital pulse. The lack of a metazoan meiofaunal response contrasts with published evidence, based on the same samples, for a substantial increase in the foraminiferal abundance following the sedimentation event. Thus our results suggest that metazoans (as a whole) fail to exploit and utilize phytodetritus as rapidly as foraminifera. This probably reflects the energetic expense of egg production coupled with frequently slower rates of somatic growth among metazoans. In addition, foraminifera may outcompete metazoans for detrital food because they possess extremely efficient food-gathering organelles (granuloreticulate pseudopodia) and are able to raise their levels of metabolic activity very rapidly. However, metazoan responses at the species level, or over longer time periods (〉3 months), would not have been detected and so remain a possibility.
