    A preliminary check-list of the phytoplankton of the Oshun River, Nigeria (1973)
    Oxford, UK : Blackwell Publishing Ltd
    Freshwater biology 3 (1973), S. 0

    Topics: Biology
    Notes: During hydrobiological investigations on the River Oshun, plankton samples were taken with a hand net of fine mesh for 14 months (May 1968-June 1969). Thirty-seven of the sixty species of algae identified have not been previously recorded in Nigeria. The qualitative character of the Oshun algae indicates the dominating nature of the floods in mixing bottom-living and rock-dwelling algae with the few euplanktonic species.

    The effect of impoundment on the water chemistry of Lake Asejire, Nigeria (1979)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: SUMMARY. Following the impoundment of the River Oshun to form Lake Asejire, Nigeria, in 1970, changes in the water chemistry were monitored. Chemical stratifications followed closely the pattern of thermal stratifications as the lake was chemically stratified from February to April and destratified from June to September and in January.

    The seasonal variation and distribution of phytoplankton in the River Oshun, Nigeria (1974)
    Oxford, UK : Blackwell Publishing Ltd
    Freshwater biology 4 (1974), S. 0 
    Details
    ISSN: 1365-2427

    Topics: Biology
    Notes: The seasonal variation in abundance of the phytopiankton groups in the river Oshun before and immediately after the closure of the Asejire dam is described.The river was dominated by the Bacillariophyceae throughout the period before impoundment but soon after, the Volcocaceae and the Dinophyceae became preponderant at the lake although the diatoms remained dominant at the source. Also, the period of maximum abundance of the diatoms occurred 8 weeks before the other phytoplankton groups attained their maxima in the river.Correlation coefficient values enumerated by computer revealed the controlling effect of the discharge, transparency and nitrate nitrogen on phytoplankton development in the Oshun.

    A new device for measuring and recording the forces applied during laryngoscopy (1995)
    Oxford, UK : Blackwell Publishing Ltd
    Anaesthesia 50 (1995), S. 0 
    Details
    ISSN: 1365-2044
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: In characterising the forces exerted during laryngoscopy it is accepted that the significant force component is that which is parallel to the axis of the laryngoscope handle. This paper describes a new method of evaluating the forces exerted at laryngoscopy. A laryngoscope handle has been redesigned, incorporating a force-displacement transducer on the handle at the end opposite to where the blade is attached. The device is designed specifically to sense the axial component of force. The blade attachment block has been detached from the sleeve and connected to a steel shaft which forms the new battery compartment. This allows the axial force exerted at the blade during laryngoscopy to be transmitted along this shaft to the sensing transducer. Linear ball bearings have been introduced between the new shaft and the handle sleeve (outer casing). The rolling friction has been reduced to less than 0.1 % by diamond-lapping the precision ground surface -hardened rod to produce a mirror finish. Thus, the force transmitted to the transducer is essentially constant regardless of where the load is applied along the blade. The output from the system is directly downloaded to a laptop computer and the data analysed almost instantaneously to determine the duration of laryngoscopy, the peak forces applied, the mean force with its standard deviation and graphic display of the data. Provision has been made for data entry checks, recording patient details and study data, and creating a data base for the storage and retrieval of the study details.

    A comparison of the forces exerted during laryngoscopy (1996)
    Oxford, UK : Blackwell Publishing Ltd
    Anaesthesia 51 (1996), S. 0 
    Details
    ISSN: 1365-2044
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: The forces exerted at laryngoscopy with the McCoy and Macintosh blades have been compared in 40 patients. The variables measured were the duration of laryngoscopy, the three maximally-applied forces and the mean force. The mean (SD) forces recorded were 18.9 (7.82) and 10.1 (5.33) N, respectively, with the Macintosh and the McCoy blades (p 〈 0.001) with a similar duration of laryngoscopy. There was a significant positive correlation between the mean force and patients' weight, height and body mass index for the Macintosh blade but only for weight and height for the McCoy blade. It is concluded that the use of the McCoy blade results in significantly less force being applied during laryngoscopy. This may be the reason for the reduction in the stress response reported previously with the use of the McCoy blade.

    Recovery of an extremely proteolytic form of Serratia liquefaciens as a pathogen of Atlantic salmon, Salmo solar, in Scotland (1990)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 36 (1990), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: During 1988, heavy mortalities were observed in three discrete populations of Atlantic salmon in Scotland. From moribund and dead animals, dense pure culture growth of an extremely proteolytic bacterium was recovered, which did not correspond to the description of any of the validly described fish pathogens. The organism, which was initially considered to have characteristics intermediate between Aeromonas veronii and Serratia liquefaciens, was eventually equated with the latter, i.e. S. liquefaciens, after seeking the advice of the Centers for Disease Control, Atlanta, U.S.A. The pathogenicity mechanism appears to involve the production of proteolytic extracellular products.

    Quantitative and qualitative studies of the bacterial microflora of turbot, Scophthalmus maximus L., gills (1988)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 32 (1988), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Populations of aerobic heterotrophic bacteria, occurring on the gills of healthy turbot, were estimated using a dilution plate technique. From a comparison of 18 media, the highest counts, i.e. 7.0 × l05 g−1, were obtained after incubation at 15–25°C on a specifically formulated medium which contained low quantities of beef extract, casein, tryptone and yeast extract. These bacteria were equated with Asticacaulis sp., Hyphomicrobium sp., Janthinobacterium lividum, Prosthecomicrobium sp., Pseudomonas fluorescens and Vibrio sp. Evidence from scanning electron microscopy pointed to a general lack of intimate colonization of exposed areas of the gill. Instead, micro-organisms colonized protected niches, such as the clefts between lamellae and in secluded areas on the arches.
