    IP RESPONSE FOR A 2D HORIZONTAL CYLINDER (1992)

    Notes: The induced polarization response for a 2D horizontal cylinder embedded in a half-space is calculated for a uniform electric source. Response curves, in the form of apparent charge-ability taking into account the effect of the air-earth interface, exhibit a sharp decrease in amplitude with an increase in depth of burial of the target. The resistivity contrast between the cylinder and the host plays a dominant role in determining the IP response, i.e. the amplitude decreases considerably with the increase in resistivity contrast. The decrease is due to the defocusing effect caused by the resistive cylinder. The current lines tend to deviate away from the cylindrical target. In the case of a highly conducting cylinder, apparent defocusing takes place as current lines are confined to the surface of the conducting cylinder. An increase in chargeability contrast is reflected as a steady rise in the response. The peak response at the centre is reduced by about half the magnitude when the air–earth interface is not considered. The variation of response along the profile, though noticeable, is not as high as that obtained at the centre.

    Notes: Protoplasts were isolated from young inflorescence-derived suspension cultures of a japonica rice cultivar ‘Taipei 177’. The isolated protoplasts which were cultured either in liquid, agar on Sea plaque agarose underwent sustained division. Maximum plating efficiency of 1.06% occurred in a medium containing macroelements of KM, microelements and vitamins of B5, 0.5 % Sea plaque agarose, 1.0 mg/l of 2,4-D, and glucose as an osmotic stabilizer. Green and albino plants were regenerated from the protocalli in MS semisolid medium containing 4 mg/l BAP, 0.5 mg/l NAA and 500 mg/l casein hydrolysate (MS18–2).

    Leachate Mound Changes in Landfills Due to Changes in Percolation by a Cap (1993)
    Oxford, UK : Blackwell Publishing Ltd
    Ground water 31 (1993), S. 0 
    Details

    Notes: A simple analytical method, adapted to hand calculations, is presented for evaluating the rise and fall of the leachate level in landfills due to possible changes of recharge caused by a landfill cap. The purpose is to provide an analytical tool for assessing the performance of landfill caps. A constant head boundary is assumed around the perimeter of the landfill, and the two-dimensional problem is solved using the linearized form of the Boussinesq equation. Percolation from rainfall or from other sources is assumed to be at a steady rate and the only source for leachate generation and mound development. The numerical results from the simple model, in terms of mound rise or decline, as a function of time, were in accord with the solution using the MODFLOW numerical model.The results of the analysis show that the level of the leachate mound is sensitive to changes in the percolation rate, and based on this, it is concluded that the effectiveness of different cap conditions can be assessed by monitoring the leachate level within the leachate mound after cap installation. The analysis is specifically applicable for landfills containing a leachate mound such as landfills in a nonarid environment and where perimeter heads are controlled.

    Interaction of enriched CO2 and water stress on the physiology of and biomass production in sweet potato grown in open-top chambers (1990)

    Notes: Abstract. The objective of this study was to investigate the effects of water stress in sweet potato (Ipomoea batatas L. [Lam] ‘Georgia Jet’) on biomass production and plant-water relationships in an enriched CO2 atmosphere. Plants were grown in pots containing sandy loam soil (Typic Paleudult) at two concentrations of elevated CO2 and two water regimes in open-top field chambers. During the first 12 d of water stress, leaf xylem potentials were higher in plants grown in a CO2 concentration of 438 and 666 μmol mol−1 than in plants grown at 364 μmol mol−1. The 364 μmol mol−1 CO2 grown plants had to be rewatered 2 d earlier than the high CO2-grown plants in response to water stress. For plants grown under water stress, the yield of storage roots and root: shoot ratio were greater at high CO2 than at 364 μmol mol−1; the increase, however, was not linear with increasing CO2 concentrations. In well-watered plants, biomass production and storage root yield increased at elevated CO2, and these were greater as compared to water-stressed plants grown at the same CO2 concentration.

    Notes: ‘Georgia-Jet’ sweet potatoes were grown at CO2 concentrations of 354, 431, 506, and 659 ppm for 90 days. Elevated CO2 concentrations decreased protein, total carotenoids and insoluble dietary fiber. An increase in dry matter and a reddish-orange color was observed at 506 and 659 ppm CO2 concentrations. Sensory evaluation scores for flavor and moistness indicated that sweet potatoes grown under high CO2 concentrations were acceptable and not different from the control.

    Monocarpic senescence in wheat: Influence of sterile glumes and ear (1986)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 67 (1986), S. 0 
    Details

    Topics: Biology
    Notes: The senescence of sterile glumes, flag leaf and the other two leaves below the ear of wheat (Triticum aestivum L. cv. Sonalika) was studied in relation to grain development and surgical manipulation. The senescence of sterile glumes was faster than that of the leaves in terms of chlorophyll and protein degradation. The flag leaf senesced later than the other two leaves below it. Removal of sterile glumes markedly reduced the harvest index (crop: straw ratio) and average dry weight per grain as compared to removal of the flag leaf. Maximum grain weight was achieved after the glumes had senesced completely. Removal of the ear delayed senescence of all the three leaves. It is concluded that sterile glumes are important suppliers of assimilate for grain filling and that nutrient drainage is the primary cause of the monocarpic senescence in wheat.

    Adherence of Vibrio parahaemolyticus to rabbit intestinal epithelial cells in vitro (1991)

    Notes: Abstract Kanagawa positive strains of Vibrio parahaemolyticus showed adherence whereas most of the Kanagawa negative strains were non-adhering to rabbit intestinal epithelial cells. Anti-hemolysin antisera did not inhibit the adherence of V. parahaemolyticus strains. Moreover, the adhesive capacity of non-adhering strains was not enhanced by purified hemolysin. Cell surface hydrophobicity remained the same in both Kanagawa positive and negative strains of V. parahaemolyticus. Fetuin strongly inhibited the adherence to rabbit intestinal epithelial cells followed by -mannose and d-glucose.

    Regulation of monocarpic senescence of Brassica campestris by the developing pods (1987)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 71 (1987), S. 0 
    Details

    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Senescence of Brassica campestris L. cv. B-9 was studied with regard to seed maturation and source-sink relationships. In normal control plants leaf senescence (as determined by the change in chlorophyll level) started and proceeded in a progressive manner from base to apex during the period of early pod setting. Complete yellowing of the leaves occurred well before the seed maturation and pod wall senescence. The pod wall always senesced before the attainment of final seed weight. In two different sets of acrocarpous plants containing 65 pods and 10 pods, respectively, leaf senescence was delayed during the pod filling period. It started non-sequentially after complete yellowing and senescence of the pod wall. The degree of leaf senescence at the post-pod filling stage was almost proportional to the number of pods present. When peduncles of the acrocarpous 10-podded plants were removed after the pod filling stage of the plant, leaf senescence was delayed compared to plants whose pedicels were removed, although the senescence pattern of the upper three leaves was nonsequential in both cases. Defruiting at an early stage of development delayed leaf senescence, although the pattern of such senescence remained unaltered (i.e. nonsequential). Defoliation hastened the seed-filling process and pod wall senescence. Plants containing fewer pods had higher average seed weight, although yield per plant was reduced.These results suggest that the pod wall serves as a temporary as well as intermediary storage organ and that foliar senescence is not directly related to seed maturation. The possible cause of uncoupling between foliar senescence and seed development is discussed.
