    Initial stages of food ingestion by Sepia officinalis (Mollusca: Cephalopoda) (1988)
    Wiley-Blackwell
    In:  Journal of Zoology, 214 (2). pp. 189-197.
    Details
    Publication Date: 2020-07-17
    Description: The cuttlefish ingests much skeleton from the crustaceans and fish it preys upon. The skeletal pieces are relatively large and their dimensions bear a close relationship to the length of the buccal mass and diameter of the oesophagus. The structures of the buccal mass are instrumental in the breakdown of prey and orientation of long pieces of skeleton to ensure their entry into the oesophagus. Many pieces of skeletal material present in the stomach contents still have attached muscles, showing that there is little, or no, external digestion. Skeletal material may be important for long-term maintenance of young Sepia in captivity.

    Benthic metabolism and standing stock in the central northern Red Sea (1987)
    Wiley-Blackwell
    In:  Marine Ecology, 8 . pp. 1-20.
    Details
    Publication Date: 2017-10-05
    Description: Benthic metabolism and standing stocks were investigated in the deep Red Sea between 21o and 27oN, Activity was assessed by the determination of respiration rates with a shipboard method and by calculating oxygen consumption from the activity in the electron transport system. We attempted to compare results from different latitudes within the warm Red Sea and with data from cold Atlantic environments. Our investigations were part of an environmental risk assessment to evaluate future mining of metalliferous sediments from the Atlantis II Deep.

    Seasonal variation in the diet of the king penguin (Aptenodytes patagonicus) at sub-Antarctic Marion Island (1987)
    Wiley-Blackwell
    In:  Journal of Zoology, 212 (2). pp. 303-324.
    Details
    Publication Date: 2020-07-17
    Description: The diet of the king penguin Aptenodytes patagonicus at Marion Island was examined throughout the year by analysis of stomach samples. Fish accounted for 87% by wet mass, 75% by numbers and 69% by reconstituted mass. Their proportional importance by wet mass increased from 68% during winter to almost 100% in summer and probably reflects a real increase in their local availability. Squid comprised most of the remainder with crustaceans forming less than 1% of the diet by numbers. Prey items were generally small, the most abundant being three species of myctophid fish, Krefftichthys anderssoni, Protomyctophum tenisonì and Electrona carlsbergi, and a squid Kondakovia longimana. King penguins took both juvenile and adult Krefftichthys anderssoni and P. tenisoni, but only adult E. carlshergi. The juvenile and adult modal size classes of K. anderssoni and P. tenisoni increased from March through to February and the proportion of juvenile to adult fish increased in winter. The increase in the modal size class of the K. anderssoni/P. tenisoni complex during the year probably reflects growth of the fish, rather than movement of different populations in and out of the area exploited by king penguins. All squid consumed were probably juveniles. The modal size class of Kondakovia longimana increased from March to August, but in September to October smaller squid again formed a large proportion of the squid component of the diet. Numbers of measurable squid beaks recovered from November to February were low. This is the first time that mesopelagic myctophid fish have been shown to comprise a major component of the diet of a vertebrate predator in the Southern Ocean.

    Size change in the phylogeny of Foraminifera (1988)
    Wiley-Blackwell
    In:  Lethaia, 21 (4). pp. 375-382.
    Details
    Publication Date: 2020-07-15
    Description: In the animal kingdom evolutionary size changes involved increasing, decreasing and stationary patterns. Planktic and benthic Foraminifera chiefly increased their size during evolution. This increase, however, did not always occur gradually, but could be interrupted by periods when the animals maintained or even decreased in size. The rate of the size increase is different for the various species examined, some benthic forms grew only 10% during the Oligocene-Pleistocene interval, while for others this figure was up to 96%. Some benthic species increased in size in certain areas, but not in others. It is not improbable that some phylogenetic trends of planktic Foraminifera representing, according to stratigraphers, the evolution of one species into another, represent in reality, from the biological point of view, specimens of the same species which changed their size and in addition some minor morphological traits which are encompassed by the normal span of intraspecific variability. A comprehensive understanding and explanation of the size change of Foraminifera needs much additional research.

    Blidingia ramifera stat. nov. (Chlorophyta): a new marine alga for eastern North America (1987)
    Wiley-Blackwell
    In:  Nordic Journal of Botany, 7 (3). pp. 359-363.
    Details
    Publication Date: 2018-10-02
    Description: Blidingia minima var. ramifera is reported for the first time in eastern North America. It occurs in the Gulf of St. Lawrence, Nova Scotia and in Maine. In the estuary of the West and Rights Rivers (Antigonish Harbour, Nova Scotia) it is the most common intertidal alga and during its maximum growth period (June‐August) covers 75–90% of the intertidal zone for several km of shoreline at the mouth of the Rights River. In culture, spore germination and early development were typical of the taxon as described from Europe. The taxon is raised to specific status as Blidingia ramifera stat. nov. Blidingia subsalsa is confirmed from New England based on observations of spore germination in plants from Maine and Connecticut.

    Gaseous diffusion in the transition pressure range (1970)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 16 (1970), S. 32-37 
    Details
    ISSN: 0001-1541
    Keywords: Chemistry ; Chemical Engineering
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Measurements of the effective self-diffusion coefficients for carbon dioxide and methane were performed in the transition pressure range. The experiments utilized carbon-14 tagged gases and semiconductor radiation detectors in a transient type of experiment. A detailed analysis of the errors associated with the experiments indicated that the accuracy of the measurements was near 5%. The results verify that the additive resistance law is valid for the representation in the transition range. The unknown effects of surface diffusion make the values to be employed in this law subject to review. As an example one surface diffusion model is considered.

    Vapor-liquid equilibria and dielectric constants for the helium-carbon dioxide system (1970)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 16 (1970), S. 97-100 
    Details
    ISSN: 0001-1541
    Keywords: Chemistry ; Chemical Engineering

    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Phase equilibria data are presented for the helium-carbon dioxide system at 253°, 273°, and 293°K. and pressures to 139 atm. Equilibrium is established under flow followed by nonflow conditions, and liquid and vapor samples are isolated without disturbing equilibrium. Liquid-and vapor-phase compositions are monitored with miniaturized capacitors, and compressibility factors are computed from resulting dielectric constants. The data are internally consistent and compare favorably with available literature values.

    Mass transfer in a nonuniform impinging jet: Part II. Boundary layer flow-mass transfer (1970)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 16 (1970), S. 90-96 
    Details
    ISSN: 0001-1541
    Keywords: Chemistry ; Chemical Engineering
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Exact solutions of the boundary layer equations were used to calculate the local mass transfer coefficients for an impinging jet with a parabolic velocity distribution. Boundary conditions were obtained from an inviscid flow solution and also from experimental pressure distributions. Experimental data for the air/naphthalene system were in good agreement with theoretical results. Mass transfer from the impingement surface was independent of nozzle height in the range 0.5 to 12 nozzle radii. For lower nozzle heights the effect of the constriction of flow between the nozzle and the surface led to increased transfer rates near the nozzle wall; data followed the predicted behavior.
