    Adverse selection, volume and transactions around dividend announcements in a continuous auction system (1996)
    Oxford, UK : Blackwell Publishing Ltd
    European financial management 2 (1996), S. 0 
    Details

    Topics: Economics
    Notes: We show that liquidity providers do not significantly respond to changes in information asymmetry risks, at least when we analyse their trading behaviour around dividend announcements of a representative sample of stocks in a continuous auction trading mechanism. the implicit bid-ask spread does not seem to change beyond what is normally conveyed through an increased number of transactions. We also document that the information in the trading behaviour of investors is primarily contained in the number of daily transactions.

    Color and Oxidative Rancidity of Gamma and Electron Beam-Irradiated Boneless Pork Chops (1996)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 61 (1996), S. 0 
    Details
    ISSN: 1750-3841

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Color and oxidative rancidity were determined for chilled (3 ± 2°C) and frozen (−17 ± 3°C) boneless pork chops packaged in vacuum or air and irradiated to an absorbed dose of 0, 1.5 or 2.5 kGy (chilled) or 0, 2.5 or 3.85 kGy (frozen) of electron beam or cobalt60 irradiation. Irradiation of vacuum-packaged chops produced redder, more stable (color and rancidity) product. More pronounced oxidative rancidity and less stable display color were noted for samples irradiated in aerobic packaging. Irradiation source had varying but limited effects on color and rancidity. Optimum packaging conditions can control color and rancidity changes in boneless chops, thereby enabling irradiation to be a useful intervention technology.

    High-pressure micro-inclusions and development of an inverted metamorphic gradient in the Santiago Schists (Ordenes Complex, NW Iberian Massif, Spain): evidence of subduction and syncollisional decompression (1995)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of metamorphic geology 13 (1995), S. 0

    Topics: Geosciences
    Notes: Abstract The Santiago Schists are located in the Basal Unit of the Ordenes Complex, one of the allochthonous complexes outcropping in the inner part of the Hercynian Belt in the north-west of the Iberian Peninsula. Their tectonothermal evolution is characterized by the development of an eo-Hercynian metamorphic episode (c. 374 Ma) of high-P, low- to intermediate-T. The mineral assemblage of the high-P episode is preserved as a very thin Si= S1 foliation included in albite porphyroblasts, being composed of: albite + garnet-I + white mica-1 + chlorite-1 + epidote + quartz + rutile ± ilmenite. The equilibrium conditions for this mineral assemblage have been estimated by means of different thermobarometers at 495 ± 10 °C and 14.7 ± 0.7 kbar (probably minimum pressure). The later evolution (syn-D2) of the schists defines a decompressive and slightly prograde P-T path which reached its thermal peak at c. 525 ± 10 °C and 7 kbar. Decompression of the unit occurred contemporaneously with an inversion of the metamorphic gradient, so that the zones of garnet-II, biotite (with an upper subzone with chloritoid) and staurolite developed from bottom to top of the formation.The estimated P-T path for the Santiago Schists suggests that the Basal Unit, probably a fragment of the Gondwana continental margin, was uplifted immediately after its subduction at the beginning of the Hercynian Orogeny. It also suggests that the greater part of the unroofing history of the unit took place in a context of ductile extension, probably related to the continued subduction of the Gondwana continental margin and the contemporaneous development of compensatory extension above it. The inverted metamorphic gradient seems related to conductive heat transferred from a zone of the mantle wedge above the subducted continental margin, when it came into contact with the upper parts of the schists along a detachment, probably of extensional character.The general metamorphic evolution of the Santiago Schists, with the development of high-P assemblages with garnet prior to decompressive and prograde parageneses with biotite, is unusual in the context of the European Hercynian Belt, and shows a close similarity to the tectonothermal evolution of several high-P, low- to intermediate-T circum-Pacific belts.

    Evidence of a new gene for high resistance to Meloidogyne spp. in Myrobalan plum, Prunus cerasifera (1998)
    Oxford, UK : Blackwell Publishing Ltd
    Plant breeding 117 (1998), S. 0

    Notes: The Myrobalan plum Prunus cerasifera clones ‘P,2175’ and ‘P,1079’ carry single major genes (Ma1 and Ma2. respectively) for resistance to the predominant root–knot nematode (RKN) species Meloidogyne arenaria (MA), Meloidogyne incognita (MI) and Meloidogyne jaranica(MJ). The Myrobalan plum clone ‘P.2980’ is another complete–spec–trum source bearing favourable agronomic features. The genetics of its resistance to MA, MI, MJ and to the population Meloidogyne sp. Florida has been investigated from G1 crosses with the host Myrobalan plum clone ‘P.16.5’ (recessive for both Ma genes), the resistant clone ‘P.2175’ (heterozygous for Mal) and the ‘Nemared’ peach (homozygous for resistance to MA, MI and MJ but a host for M. sp. Florida). The segregation of the Gl hybrids from the intraspecific crosses into two significantly separated resistant and host classes, independent of the RKN species, indicates that resistance to all four species in ‘P.2980’ is also controlled by a single major dominant (heterozygous) gene. This gene is designated Ma3 because it shares the same spectrum and efficiency as Ma1 and Ma2, and its relationship with these last two genes is discussed. The first hybrids between ‘P.2980’ and ‘Nemared’ tested only segregated for resistance to M. sp. Florida. These results illustrate the possibility of cumulating (pyramiding) Ma3 and the ‘Nemared’ peach resistance gene(s) into new interspecific rootstocks.

    Effect of the gene for double pod in chickpea on yield, yield components and stability of yield (1998)
    Oxford, UK : Blackwell Publishing Ltd
    Plant breeding 117 (1998), S. 0

    Notes: Five pairs of near isogenic lines (NILs) for the gene for single vs. double pod were used to study the effect of this character on yield and its components (seeds per plant, yield per plant and seed weight). The NILs were sown in 2 years at five locations in ihe first year and four locations in the second. Combined analysis of variance was applied to t he data and no significant differences between isolines were found, but there were significant genotype– location interaction effects for yield and seeds per plant. For both characters the double–podded lines were more stable than the single–podded lines. Although there were significant differences between the five genotypes lor yield per planl and seed weight, the differentes between single– and double–podded lines were almost nil. The results indicate that the double–pod gene has a positive effect on the stability of yield and is not linked to any other gene responsible Tor seed size in chickpea

    Purification of plasma membranes from dry maize embryos (1997)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 101 (1997), S. 0 
    Details
    ISSN: 1399-3054
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Isolation of subcellular fractions from dry structures such as seeds or their tissues is difficult. In the present work, plasma membranes were isolated from dry maize (Zea mays L.) embryos with an enrichment of 11-fold as estimated by glucan synthase II (GSII, EC 2.4.1.34) activity and a purity of 78 to 90% as judged by the sensitivity of ATP hydrolysis to vanadate, a specific inhibitor of the plasma membrane H+-ATPase (EC 3.6.1.35). The procedure involved a double homogenization of the dry embryos and the addition of a 1500-g supernatant to an aqueous polyethyleneglycol-dextran two-phase partitioning system; the optimal ratio of polyethyleneglycol-dextran for purification of plasma membranes from dry seeds was 6.8/6.8% (w/w). In the isolated membranes a trace of a tonoplast enzyme marker (tonoplast H+-ATPase, EC 3.6.1.3) could be detected, but there were negligible amounts of mitochondrial and rough endoplasmic reticulum markers, H+-ATPase (EC 3.6.1.34) and diacylglycerol acyltrans-ferase (EC 2.3.1.20), respectively. The technique could also be used in hydrated embryos. The entire procedure can be carried out in 5 to 6 h. The resulting preparation is stable for at least 2 months at −70°C. The membranes of dry and hydrated embryos exhibited a high level of vanadate-sensitive ATPase activity that was increased by lysophosphatidylcholine.

    Notes: RAPD markers were developed for octoploid X Tritordeum (amphiploid Hordeum chilense × Triticum aestivum) and its parents. Two bread wheats, two H. chilense accessions and the two tritordeums synthesized with them were used. A total of 41 arbitrary decamer primers were tested, yielding 190 products that could be assigned to wheat, 185 to H. chilense and 108 that were nonspecific (present in wheat and barley). A total of 44 products were specific to one H. chilense line and 33 to the other 16 of the former were located on the chromosomes using a set of H. chilense in T. aestivum addition lines. The potential of RAPDs for developing addition lines or the detection of introgressions of H. chilense in bread wheat is discussed.
