    Biomass and respiratory ETS activity of microplankton in the Barents Sea (1991)
    Oxford, UK : Blackwell Publishing Ltd
    Polar research 10 (1991), S. 0 
    Details
    ISSN: 1751-8369
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Geography , Geosciences
    Notes: The activity of the respiratory electron transport system (ETS) of microplankton was measured in the Central Barents Sea during summer 1988. In vitro ETS activity increased with assay temperature between 0 and 2°C, as reported for other enzyme systems in plankton. The higher in situ activities were observed near the surface (upper 10-25 m) and were associated with chlorophyll a maxima. Respiratory activity in the upper 60 m accounted for 40-60% of the total column respiration. The activities (0-100 m) were lower than oxygen consumption rates reported in the Canadian Arctic, mainly due to lower phytoplankton biomass. They were higher than ETS activity measured in the Weddell Sea (Antarctic Ocean). A high detrital versus total microplankton mass accounted for the low activity related to particulate organic carbon (POC). In general, the levels of respiratory ETS activity were in the range reported for temperate oligotrophic oceanic regions.

    Hatching of the queen conch, Strombus gigas L., based on early life studies (1991)
    Oxford, UK : Blackwell Publishing Ltd
    Aquaculture research 22 (1991), S. 0 
    Details
    ISSN: 1365-2109
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Abstract. This study is based on a description of the anatomical development of live eggs and larval characteristics of queen conch, Strombus gigas L., before hatching, and the development of these characteristics at five different temperatures (24°C, 26°C, 28°C, 30°C and 32°C). The effect of temperature was quantified with reference to six easily identifiable morphological changes, selected from 27 identified characteristics. The relationship between the appearance of the six characteristics and water temperature was used to calculate the minimal biological temperature (MBT) for queen conch. The “degree days” for each characteristic until hatching were determined. These data can be used to predict ihc hatching time at predetermined temperatures in culture systems. The work also has the benefit of providing synchronously developed material for S. gigas for developmental, biological, physiological and biochemical research of this species.

    Variability among Spanish citrus tristeza virus isolates revealed by double-stranded RNA analysis (1991)
    Oxford, UK : Blackwell Publishing Ltd
    Plant pathology 40 (1991), S. 0 
    Details
    ISSN: 1365-3059
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: A survey for citrus tristeza virus (CTV) strains, based on double-stranded RNA (dsRNA) analysis, was carried out in five locations on the eastern citrus-growing area of Spain. CTV was recovered from 137 trees of different ages, citrus species and varieties, sampled in 53 orchards. The best months for dsRNA recovery were April, May, September, October, and November, and the highest dsRNA yield was obtained from sweet orange cultivars. Sixteen dsRNA profiles differing by the number and/or position of subgenomic bands were detected. One of these profiles was detected in more than half the trees analysed. Maximum diversity of dsRNA patterns was found in the location with the oldest citrus orchards and the highest CTV incidence (Alzira-Carcaixent). In many instances, several dsRNA profiles were detected in neighbouring trees of the same orchard, notably in Alzira-Carcaixent, where 70% of the plots sampled contained more than one profile. The possible causes for the diversity of CTV isolates found in this specific area are discussed.

    Electrophoretic analysis of protein variation in two Spanish populations of the European seabass, Dicentrarchus labrax L. (Pisces, Moronidae) (1991)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Abstract. One hundred specimens of the European seabass. Dicentrarchus labrax L., from a natural population (Cádiz, Spain) were analysed by starch gel electrophoresis for 23 enzymes; 49 loci were identified, of which five were polymorphic (ADH*, AAT-3*, EST-.3*, MEP-1* and SOD-2*) P = 10·2% and HQ = 1·8%. Twenty specimens from a hatchery at Tinamenor in northern Spain (Fl progeny from wild) were analysed for 28 different enzymes. A total of 61 loci were identified of which 4 were polymorphic (LDH-1*, LDH-2*, MEP-1*, and XDH-2*) P = 6·6%,Ho= 1·5%. A total of 31 enzyme systems and 79 different loci were analysed in the two populations. The results suggest that the Cádiz and Tinamenor stocks are reproductively isolated and show a level of stock differentiation not previously known in populations of this species. An estimate of genetic distance based on the 31 loci compared in both populations gave a value of D=0·012+0·018 and a genetic similarity of I=0·988. The implications of these results for fisheries and aquaculture are briefly discussed.

    CONSULTANT'S CORNER PROPOSING THE INTERNATIONAL SENSORY JUDGES DAY (1991)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of sensory studies 6 (1991), S. 0 
    Details

    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: A panel of trained sensory judges is a sensitive and valuable instrument. and a lot of time and work is invested in their selection and training. The importance of internal motivation and external stimulation to maintain the interest and wellbeing of these human instruments is supported by major food scientists and behavioral psychologists. Current stimulation procedures for sensory judges are listed. A new procedure is proposed, consisting of an annual celebration party on November 20 in recognition of sensory judges. Advantages of holding this day on an international level are discussed: mainly, promotion of fellowship among sensory judges from different groups and countries, and also its help in increasing cooperation in sensory evaluation. Actions to promote International Sensory Judges Day are listed. Suggestions for the actual celebration party are put forward: an open house luncheon, presentation of awards, greeting cards and letters from other sensory panels; and last but not least, a set of proven “sensory” games where everyone joins in.

    Notes: Abstract. This paper describes the histopathological changes observed in the Mexican native cichlid Cichlasoma urophthalmus (Günther) when try with an initial weight of between 160 and 170 mg were fed with diets deficient in vitamin C for 90 days. The epidermis showed an extensive inflammatory response, with spongiosis and also degenerative changes in the basal cells. Muscle showed a range of pathological changes including inflammation, changes in the number and position of the nuclei, vacuolation and necrosis, granular degeneration, and fibre loss. Gills showed thickening of the primary lamellae, oedema, hyperplasia, telangiectasis and atrophy of the bony supporting structures. Ganglia and neurones of nervous tissue were abnormal with changes which ranged from slight inflammation to central chromatolysis. The hepalopanereas was also affected and focal necrosis of the hepatocytes was frequently observed. The pancreas showed major changes with shrinkage of the acinar cells and reduction of zymogen granule content. Fish fed diets containing 0 and 40 mg vitamin C kg-1 of diet were infected with Mycobacterium sp. and miliary tuberculosis was found affecting kidney, spleen, choroid gland, stomach, heart and muscle. The association between fish tuberculosis and vitamin C deficiency is discussed.

    τ-p SEISMIC DATA FOR VISCOELASTIC MEDIA – PART 1: MODELLING (1991)

    Notes: Viscoelastic modelling reveals that the interaction of compressional-wave velocity Cp, compressional-wave quality factor Qp, shear-wave velocity Cs, shear-wave quality factor Qs and Poisson's ratio as a function of time intercept τ and ray parameter p, is complicated; however, distinct, potentially diagnostic behaviours are seen for different combinations of viscoelastic parameters.Synthetic seismograms for three viscoelastic reservoir models show that variations in the Poisson's ratio produce visible differences when compared to the corresponding elastic synthetic seismograms; these differences are attributable to interaction of the elastic parameters with Qp and Qs.When the P-wave acoustic impedance contrast is small, viscoelastic effects become more apparent and more useful for interpretation purposes. The corresponding amplitude and net phase spectra reveal significant differences between the elastic and the viscoelastic responses. When P-wave reflectivities are large, they tend to dominate the total response and to mask the Q reflectivity effects. The attenuation effects are manifested as an amplitude decay that increases with both time and ray parameter.The sensitivity of the computed seismic responses for various combinations of viscoelastic parameters suggests the opportunity for diagnostic interpretation of τ-p seismic data. The interpretation of the viscoelastic parameters can permit a better understanding of the rock types and pore fluid distribution existing in the subsurface.

    τ-p SEISMIC DATA FOR VISCOELASTIC MEDIA - PART 2: LINEARIZED INVERSION (1991)

    Notes: An approach to extraction of viscoelastic parameters from seismic data is implemented and succesfully tested. Viscoelastic inversion is performed using adaptive damping factors to control the sensitivity of the viscoelastic parameters in relation to the τ-p seismic data. A priori information is incorporated through the damping factors as standard deviations of the data and of the viscoelastic model parameters. The stability of the inversion process is controlled by the variation of the damping factors as a function of the residual errors and parameter updates at each iteration.Tests on synthetic and real data show that P- and S-wave quality factors, Qp and Qs, in addition to P- and S-wave velocities and density Cp, Cs and p, can be extracted from τ-p seismic information. Singular value decomposition analysis demonstrates that estimated Qp and Qs values are more affected by the presence of data inaccuracies and noise than are those of Cp and p. Cs and Qs are not uniquely recovered due to the limited contribution of P-S converted waves.Knowledge of the viscoelastic parameters is of particular importance in accurately describing petrophysical properties of rocks and pore fluids existing in the subsurface; this is demonstrated with real data from the Gulf of Mexico.
