    Spectral analyses of offshore magnetic data for computing depths to the basement rocks (1984)
    Springer
    Marine geophysical researches 6 (1984), S. 245-256 
    Details
    ISSN: 1573-0581

    Topics: Geosciences , Physics
    Notes: Abstract This paper deals with the computation of the depth to the magnetic interface from the total magnetic field intensity values obtained along profiles in the offshore area between Vengurla and Rajapur bay off the West Coast of India, by the application of one dimensional spectral analysis method. From the response characteristics of the total field magnetic values it is surmised that the magnetic interface may be identified with the Deccan trap series of rocks which are likely to form the magnetic basement rocks in this area. The plot of depths to the basement rocks as obtained from spectral analysis indicates that the basement is sloping towards outer edge of the Continental Shelf though not uniformly.

    Energy dependence of the fast fragment of the target nucleus in high energy hadron-nucleus interaction (1982)
    Springer
    Czechoslovak journal of physics 32 (1982), S. 1221-1224

    Notes: Abstract This paper presents an extensive study on the dependence of the mean number of the fast fragment of the target nucleus 〈n g〉 on the incident beam energy in proton-nucleus interaction in emulsion in the range 6·2≦E 0≦400 GeV/c. It has been observed that 〈n g〉 decreases in the range 6·2≦E 0≦200 GeV/c, then increases and attains an approximately steady value up to 400 GeV/c. It is very difficult to explain this behaviour with the help of the existing nuclear production models.

    Radial motion of a solid spherical body in a magnetic field (1980)
    Springer
    Czechoslovak journal of physics 30 (1980), S. 1115-1126 
    Details
    ISSN: 1572-9486
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The object of the present paper is to investigate the radial motion of a solid spherical body, assumed to be homogeneous, isotropic and elastic, in presence of a magnetic field in the azimuthal direction. The body is assumed to be in a state of initial stress which is hydrostatic in nature. This theory of radial motion of a solid spherical body in a magnetic field has been utilised to find the small radial motion of a solid Earth assumed to be homogeneous isotropic elastic sphere in presence of a magnetic field in the azimuthal direction. Considering the effect of gravity and the initial stress produced by slow process of creep due to extra masses over the surface of the Earth, the fundamental equations of motion are derived which are non-linear in character and are solved. The times of a desired radial displacement are calculated in presence of a magnetic field only and in presence of the same magnetic field, initial stress and gravitational field, which are compared and exhibited numerically.

    Notes: Summary The kinetics of oxidation of some neutralized α-hydroxy acids such as lactic (LA), mandelic (MA), α-hydroxyisobutyric (IB) and benzilic (BA) acid by hexachloroiridate(IV) have been studied. The oxidation products are acetaldehyde, benzaldehyde, acetone and benzophenone for the respective reactions, which are first order with respect to each substrate and to iridium(IV). The reaction rate increases with increase in pH and salt concentrations. The temperature influence is quite marked in all these reactions. A mechanism involving the formation of an unstable complex, which decomposesvia a free radical pathway to give the respective reaction products, is proposed.

    Notes: Summary Schiff base complexes of trichloro(cyclopentadienyl)titanium(IV) having the general formulae CpTiCl3SB and CpTiCl(SB') (where SB=Schiff bases derived from thiocarbohydrazide and benzaldehyde,m-nitrobenzaldehyde,p-nitrobenzaldehyde, acetophenone,p-hydroxyacetophenone, anisaldehyde, cinnamaldehyde and vanilline; SB'H2=Schiff bases derived from thiocarbohydrazide and salicylaldehyde, oro-hydroxyacetophenone) have been synthesized by reaction of appropriate Schiff base with trichloro(cyclopentadienyl)-titanium in anhydrous dichloromethane. The complexes were characterized by elemental analysis, electrical conductance, magnetic measurements and spectral (electronic, i.r. and1H n.m.r.) studies. Proton n.m.r. spectra indicate that there is rapid rotation of the cyclopentadienyl ring around the metal-ring axis on the n.m.r. time scale at 25°C.

    Post-translational processing of 7S and 11S components of soybean storage proteins (1981)
    Springer
    Plant molecular biology 1 (1981), S. 19-34 
    Details
    ISSN: 1573-5028
    Keywords: Glycine max ; storage protein biosynthesis ; in vitro translation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The synthesis and processing of the major storage proteins in soybean cotyledons was studied both in vivo and in vitro. The α and α′ subunits of 7S as well as the 11S proteins are synthesized as higher molecular weight-precursors on membrane-bound polysomes. The initial translation products of the 7S are proteolytically cleaved during translation suggesting the removal of a ‘signal peptide’ as evidenced by the presence of 2α and 2α′ peptides immunoreactive with 7S antibody in the in vitro chain completion products of the membrane-bound polysomes. This is followed or accompanied by cotranslational glycosylation, which increases their size equivalent to that of initially-synthesized precursors. In vivo pulse-labelled 7S α and α′ products are of slightly higher molecular weights than the immunoprecipitable chain-completion products, indicating further post-translational modifications. A slow post-translational processing during a period of 1.5 to 16 h yields the final 7S α and α′ glycoproteins. Acidic and basic subunits of the 11S protein appear to be synthesized from common large molecular weight (60K-59K) precursors. Antibodies to the 11S acidic component recognize both acidic and basic domains in the precursor while those raised against basic subunits appear to be specific for that region only. The processing of the 11S precursor is also very slow and occurs post-translationally. This slow rate of processing, coupled with a temporal difference in the synthesis of 7S and 11S components, suggests a highly coordinated mechanism for synthesis and packaging of these proteins into protein bodies during seed development.

    Structure of soybean Kunitz trypsin inhibitor mRNA determined from cDNA by using oligodeoxynucleotide primers (1984)
    Springer
    Plant molecular biology 3 (1984), S. 111-117 
    Details
    ISSN: 1573-5028
    Keywords: oligodeoxynucleotide primers ; soybean trypsin inhibitor
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Oligodeoxynucleotides complementary to the deduced mRNA sequence of soybean Kunitz trypsin inhibitor (KTI) were used to prime the synthesis of cDNA from soybean cotyledon total poly(A) RNA. The primed cDNA was used to select clones from a Glycine max cotyledon cDNA library. Two out of twelve hybridizing clones were shown to contain KTI cDNA. The nucleotide sequence of one clone, pSTI 9-2, was determined and it was found to encompass the complete protein coding region of KTI excet for three C-terminal residues. Trypsin inhibitor is synthesized with a 25 amino acid hydrophobic N-terminal sequence presumed to be a signal peptide. The mature polypeptide encoded by pSTI 9-2 agrees with the published amino acid composition of KTI, but contains two discrepancies at the peptide sequence level.

    Localization and identity of adenosine deaminase-positive cells in tissues of the young rat and calf (1983)

    Notes: Summary Rabbit antibody to calf adenosine deaminase (ADA) was used to localize this enzyme in tissues of the young rat and calf by the immunoperoxidase method. The distribution patterns of ADA in most tissues were similar for both species. Within the thymus gland, the enzyme was strongly expressed predominantly in cortical lymphocytes. In the spleen and lymph nodes, most lymphocyles of T-cell areas stained weakly for ADA, whereas only a small number of ADA-positive cells were found in B-cell areas. Clumps of strongly ADA-positive mononuclear blastoid and plasma cells were observed in the medullary regions of lymph nodes, around peri-arteriolar lymphocyte sheaths and in the red pulp of the spleen, and in the lamina propria of the intestine. Double immunofluorescence staining studies in the rat showed that some of these blastoid cells contained both ADA and immunoglobulins and appeared to be plasmablasts. Strong staining for ADA was also found, in both the rat and calf, in as yet unidentified mononuclear blastoid cells in the inter-stitium of non-lymphoid organs (kidney, heart, lung), in endothelial cells of some arterioles and capillaries, and in Kupffer cells of the liver. In addition, ADA was strongly expressed in calf bile canaliculi. These studies define areas in rat and calf tissues which contain ADA-positive cells and provide a model system for investigations of the relationship between ADA and the function and development of these cells.
