    ON THE ENERGY REQUIRED TO FORM THE MOON (1954)
    Oxford, UK : Blackwell Publishing Ltd
    Geophysical journal international 6 (1954), S. 0

    Notes: The energy in various model primitive Earth-Moon bodies containing a normal phase X and two high-pressure phases Y and Z has been examined. In each model, the first high-pressure phase Y has been taken to be in agreement with the data for the outer central core of Bullen's Earth Model B. On certain simplifying assumptions, it is then shown that disappearance of the phase Z from the primitive body would be accompanied by the release of sufficient energy to eject a body of the Moon's mass, provided that the radius of the region occupied by the phase Z was at least about 1500 km and that the density of Z is at least about 18 g/cm3. This result gives some quantitative support to Bullen's theory of the origin of the Moon, provided that his suggested mechanism of resonance could lead to sufficient distortion to take the primitive body over a potential barrier into the state in which the phase Z has disappeared.

    A neotype and 2 topotypes for Bola chaptis Hamilton, 1822 (Pisces, Sciaenidae) (1972)

    Notes: Hamilton (1822) described and figured Bola chaptis from the River Ganges, but left no type material. Trewavas & Talwar (1972, p. 11) have described a species that they believe identical with B. chaptis and placed it in the genus Bahaba Herre. Since their specimens came from Burma they did not propose a neotype from among them. During the course of a taxonomic study of the family Sciaenidae, 3 well-preserved specimens in the collections of the Zoological Survey of India were recognized by us as the same species. They were collected by the junior author at Chinsura in the Hooghly estuary during September 1954. This discovery supports the decision of Trewavas and Talwar to use Hamilton's name and after consultation with Dr Trewavas we have decided to select one of these specimens as neotype of Bahaba chaptis (Hamilton).

    Computer-Based Retort Control Logic for On-Line Correction of Process Deviations (1986)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 51 (1986), S. 0

    Notes: A control logic algorithm is described for use with computer-based control systems on batch retort operations in the thermal processing of canned foods. The system is capable of automatically adjusting process time during the cook cycle to compensate precisely for any unexpected deviation in retort temperature. It takes into account the cooling lethality contributed with conduction-heating foods, and does not rely on any test cans for monitoring product center temperature. Performance is demonstrated by computer-generated plots showing actual retort temperature history along with calculated center temperature and accumulated process lethality; and results are compared with other methods.

    Notes: Hydrostatic creep tests were run on cylindrical specimens of Rome Beauty apples to study the mechanical response. Volumetric strain was measured for different levels and durations of applied stress. The former was separated into recoverable, permanent, instantaneous, and time dependent components. A general constitntive relationship was developed from statistical analysis. A mechanical model was proposed to explain the strain response of the material.

    Notes: A cell-associated mannose/glucose-specific hemagglutinin (MSHA) has been purified from a strain of Vibrio cholerae O1 by chromatography on a chitin column followed by affinity purification on Sephadex G100. The purified protein gave a single stained band of 40 kDa by SDS-PAGE, exhibited high affinity towards d-mannose and d-glucose but was resistant to l-fucose and N-acetyl-d-glucosamine. The purified MSHA was revealed as a globular form of protein under electron microscope. In immunodiffusion tests the purified MSHA produced a single precipitin band against homologous antisera and antisera raised against the whole cell bacteria without any reactivity towards antisera raised against the purified N-acetyl-d-glucosamine-specific lectin of the same bacterial strain. Immunogold labelling confirmed the location of hemagglutinin on the surface of the bacteria. Purified MSHA reacted strongly with sera from convalescent cholera patients in immunodiffusion tests.

    Notes: Abstract An N-acetyl-d-glucosamine-specific cell associated hemagglutinin (HA) was isolated and purified from a strain of Vibrio cholerae 01 by chitin affinity chromatography followed by separation on Bio Gel P-150. A single stained protein band of 47 kDa in sodium dodecyl sulfate-polyacryl-amide gel electrophoresis (SDS-PAGE) was observed with the purified HA. HA-antisera produced a single precipitin band against the purified HA in an immunodiffusion test without exhibiting any reactivity towards purified lipopolysaccharide (LPS). Purified HA, used as solid-phase antigen in an enzyme-linked immunosorbent assay (ELISA), reacted strongly with HA-antisera but cross-reacted negligibly with antisera raised against purified LPS. Hemagglutinating activity of the purified HA was highly sensitive to N-acetyl-d-glucosamine. The immunogold-labelling method using HA-antisera confirmed the location of the HA on the surface of the bacterial cells. The HA-antisera reacted with

    Notes: A hemolysin was purified from a Vibrio cholerae O139 strain which moved as a single protein band of 67 kDa in SDS-PAGE. The hemolysin showed high level of phospholipase C activity. The purified phospholipase C–hemolysin demonstrated enterotoxic activity in rabbit ileal loop, suckling mice and enhanced permeability of rabbit skin. The pI of the purified hemolysin was 6.4. Erythrocytes from rabbit, chicken, guinea pig, sheep and horse were sensitive to the purified hemolysin in decreasing order of intensity. Erythrocytes from human and cow were unaffected by purified hemolysin.

    Adhesion and invasion of a mutant Shigella flexneri to an eukaryotic cell line in absence of the 220-kb virulence plasmid (1999)

    Notes: A Shigella flexneri strain, cured of the large 220-kb virulence plasmid, expresses adhering and invading ability in confluent monolayers of HeLa cells similar to its parent strain. Invasion by both the parent and the cured strains resulted in alteration of the monomeric actin (G) in the total actin pool of HeLa cells. Other indicators of invasive characteristics of virulent Shigella strains such as production of keratoconjunctivitis in guinea pig eye in vivo, Congo red binding and expression of contact hemolysin however, indicated loss of invasive properties in the plasmid cured strain. Further, pretreatment of bacterial cells with para-bromophenacyl bromide (p-BPB), a specific chemical inhibitor of phospholipase A, adversely affected adhesion to and invasion of HeLa cells in vitro, irrespective of the presence of the 220-kb plasmid indicating the possible involvement of the enzyme phospholipase A in the invasion process. Adherence of both the strains to guinea pig colonic epithelial cells (CECs) in vitro was reduced significantly on pretreatment of bacteria or CECs with p-BPB. Expression of exocellular enzymes viz. protease, elastase, phospholipase A and phospholipase C were not related to the large plasmid.

    Notes: The presence of three major virulence genes toxR, tcpA and ctxA as well as expression of several putative virulence factors were compared in 12 Vibrio cholerae O139 and non-O1,non-O139 strains of clinical and environmental origin. All the strains possessed the gene encoding the regulatory protein TOXR. None of the non-O1, non-O139 strains as well as one of the O139 environmental strains carried the genes for ctxA and tcpA. Statistically significant differences in hemagglutinin and hemolysin production were observed amongst the strains depending on the source of their isolation. Expression of extracellular enzymes such as protease, elastase, neuraminidase, phospholipase A and phospholipase C, however, did not vary significantly from the groups of strains isolated from different sources.

    Notes: Abstract The outer membrane (OM) protein components of a Vibrio cholerae O1 and four V. cholerae O139 strains, collected from cholera patients, were analysed by SDS-PAGE. A protein of 69 kDa molecular mass was observed only when the OMPs were prepared from strains grown in synthetic broth. As a result of passage in the rabbit ileal loop (RIL), virulence was enhanced, and a protein component around 18 kDa of the V. cholerae O139 OM became the major protein component. On immunoblot analysis with rabbit antiserum against V. cholerae O139 OM, it was shown that, apart from the major protein component of V. cholerae O1 OM of around 45 kDa and that of V. cholerae O139 OM of around 38 kDa, all other minor protein components were cross-reactive between the two serogroups. In immunoblot assays with convalescent sera obtained from V. cholerae O139-infected patients, it was observed that in addition to the lipopolysaccharide (LPS)-induced antibody, only the 38 kDa major protein component elicited considerable levels of antibody in the pateint. Minor OM components of 18 kDa were detected in the immunoblot analysis by LPS-directed antibody, however, as the OM proteins are known to be associated with LPS.
