    Relationships between Control of Wheat Bulb Fly (Leptohylemyia coarctata (Fall.)) and Amounts of Dieldrin, Carbophenothion and Chlorfenvinphos on Treated Seed (1976)

    Notes: Trials were done in eastern England in 1972–74 to study relationships between control of wheat bulb fly larvae and amounts of insecticide on treated seed. Carbophenothion in short-row trials in 1972–73 was relatively ineffective even at the largest dose, 100 μg/seed. Chlorfenvinphos at low dosages did not significantly decrease the percentage of plants with live larvae but was increasingly effective as the dosage increased. Dieldrin decreased the percentage of plants with live larvae even at small dosages, about 10 μg/seed. Clilorfenvinphos was further studied in larger plots (c. 0.01 ha) in 1973–74. Plant examinations confirmed results of the previous year but large yield increases were obtained at only two of four sites, one with the greatest plant attack (55 per cent damaged shoots) and the other with the latest sowing date (22 November).

    Absorption spectra and magneto-optic figures of merit in the Bi x Sm3-x Fe5-y Ga y O12 system (1976)

    Notes: Abstract The absorption (α) and Faraday rotation (θ) spectra of 14 garnets belonging to the series Bi x Sm3-x Fe5-y Ga y O12 (0〈x〈1.05, 0.8〈y〈1.15) have been measured between 15 000 cm−1 and 19 000 cm−1. The figure of merit (θ/α) at 17 850 cm−1 (560 nm) increases linearly with increasing bismuth concentration up tox∼0.6 where it begins to increase less rapidly. For operation of magneto-optic display devices at 17 850 cm−1 there is no advantage in using garnets in this series withx〉0.8. The Faraday rotation at 17 850 cm−1 increases linearly with bismuth concentration whereas the absorption coefficient increases more rapidly. The presence of Bi3+ increases the intensity of all Fe3+ pair transitions in the garnet system as a result of the increased superexchange induced by Bi3+. This is in keeping with the observation that the intensity of the6A1g (S)→4T1g (G) transition in (RE)3Fe5O12 (RE=Er, Y, Dy, Gd, Eu) increases on traversing the above RE series as do the Curie temperatures of these iron garnets.

    Notes: Résumé La présence des globulines lentes α1 et α2 dans la rate des rats normaux est révélée par les techniques immunofluorescentes et immuno-péroxydasiques. En microscopie électronique, les globulines α-lentes semblent se trouver dans les phagosomes. Dans le cas de la globuline α1-lente, le nombre des phagocytes varie avec l'âge du rat. Ils sont presque absents jusqu'à la 18ième semaine. Par contre le nombre de phagocytes contenant la globuline α2 reste constant.

    Bis(diisopropyl) thiophosphoryl disulfide in cis-1,4-polyisoprene vulcanization reactions. I. As a sulfur donor (1975)

    Notes: Bis(diisopropyl)thiophosphoryl disulfide (DIPDIS) is used as a sulfur donor vulcanizing system for cis-1,4-polyisoprene. It is shown that the network structure consists of poly- and disulfidic crosslinks at early stages of cure, simplifying at optimum cure to monosulfidic crosslinks. It is thought that pendent accelerator groups are bound to the rubber molecule at early stages of cure, but are subsequently replaced by cyclic sulfidic groups. The good thermal and thermal oxidative aging behaviour of the vulcanizate is due to the formation of zinc diisopropyldithiophosphate (ZDP) in situ.

    Bis(diisopropyl)thiophosphoryl sulfides in vulcanization reactions (1979)

    Notes: A synergistic combination of bis(diisopropyl)thiophosphoryl disulfide, dimorpholyl disulfide, and sulfur is used to produce an efficient vulcanizing system for a range of rubbers. This produces vulcanizates with the exceptional thermal and thermal-oxidative stability characteristic of sulfur donor vulcanizates and the rapid and extensive crosslinking reaction normally associated with a conventional sulfur-accelerator combination. A pronounced induction period is noted. The crosslinks initially produced in cis-1,4-polyisoprene rubbers are predominantly polysulfide but reduce to mono- and disulfides at optimum and extended cures. The crosslinks of the ethylene-propylene terpolymer and the styrene-butadiene vulcanizates are initially mainly disulfide but are rapidly reduced to monosulfides at the high curing temperatures (180°C) used. A comparison with vulcanization systems based on tetramethylthiuram disulfide and bis(diisopropyl)thiophosphoryl tri-and tetrasulfides as sulfur donors and with a conventional cyclohexylbenthazyl-2-sulfenamide-sulfur combination, respectively, shows it to have distinct advantages.

    Notes: Scalopus membranes are characterized by: Superficial nidation; antimesometrial orientation of the embryonic disc; amniogenesis by folding; an extensive but transitory choriovitelline placenta; a large yolk sac with late and incomplete inversion; large persistent allantoic vesicle; a very broad, thin, villous, epitheliochorial chorioallantoic placenta of annular shape interrupted mesometrially, dotted with numerous areolae, and bordered by a non-villous sparsely vascular chorioallantoic membrane connected with the persistent bilaminar omphalopleure by a very narrow rim of chorion. There is no decidua. Electron microscopy shows that at 8 mm, CR, (limb bud embryo) the uterine epithelium of the interhemal membrane may be 0.5 μm or less in thickness, but that it shows no signs of degeneration. Trophoblastic microvilli often penetrate the epithelium to within 0.2 μm of its base. At this time there is active secretion by the uterine glands, and cellular hypertrophy and cytolysis of the epithelium at the gland mouths, with active phagocytosis by the areolar cytotrophoblast. The occurrence of absorptive areolae in an insectivore emphasizes the probable primitiveness of this widely distributed placental mechanism. In spite of similarities of the yolk sac to that of rabbits and rodents, the bilaminar omphalopleure produces no invasive trophoblastic giant cells. The definitive membranes of Parascalops breweri and Scapanus latimanus are like those of Scalopus. The placentae of Talpa europaea, Condylura cristata, and Neurotrichus gibbsii are discoid and relatively much smaller, thicker and more complex in internal structure. There is some reason to believe that the fetal membrane systems of moles and shrews (Soricoidea) are more like those of the ancestral mammalian stock than are those of any other recent eutherians.
