    SEPARATION OF TWO-DIMENSIONAL RESIDUAL GRAVITY ANOMALIES USING LATERAL DENSITY VARIATION (1974)

    Notes: A set of parabolae is defined to approximate the observed gravity profile for specifying the lateral density variation in a two dimensional causative body. This variation separates the “biased” as well as “unbiased” residual anomaly structure. The method may be directly incorporated into existing numerical and graphical techniques of interpretation for subsequent delineation of structural configuration. The simple relations derived by inspection of the observed gravity profile permit universal application of the technique and in particular for the determination of the size and shape of sub-shelf structures. The suitability of the method in various problems of two dimensional interpretation has been indicated through an illustration of the Godavari Basin (India).

    A palaeomagnetic study of Cainozoic basalts from Northern Nigeria (1991)
    Oxford, UK : Blackwell Publishing Ltd
    Geophysical journal international 106 (1991), S. 0 
    Details

    Topics: Geosciences
    Notes: Palaeomagnetic results are presented for 95 specimens from 10 sites from the Jos Plateau Cainozoic basalts in the Northern Nigeria volcanic province. Available K–Ar age determinations from this area suggest that the rocks formed during the Pleistocene. After alternating field demagnetization, the mean direction of the natural remanent magnetization is D= 341.7°, I=–8.7° with α95= 4.2°. This yields a virtual geomagnetic pole position of 67.0°S, 63.0°E.An estimated average palaeomagnetic latitude of about 4.4°S for the area of study when compared with the present geographic latitude of about 9.5°N, implies a latitudinal northward drift of about 14° for the African plate since the time of formation of the rocks. This is incompatible with current models for plate motions and most likely represents the effects of conditional local tectonic movements or departures of the geomagnetic field from an axial dipole configuration.

    Defined starter system including a bacteriocin producer for the enhancement of cheese flavour (1999)
    Springer
    Biotechnology techniques 13 (1999), S. 267-270 
    Details
    ISSN: 1573-6784
    Keywords: bacteriocin ; cheese ; flavour ; lysis ; starter

    Notes: Abstract Defined starter systems, consisting of bacteriocin-tolerant Lactococcus lactis subsp. lactis H6 alone or in combination with bacteriocin-sensitive L. lactis subsp. cremoris H1, and low amounts of a bacteriocin-producing culture, were developed and used for the manufacture of semi-hard cheese. Aminopeptidase activity and proteolysis were increased and acidification retarded in cheeses made from milk inoculated with lactococci and the bacteriocin-producing culture with respect to cheeses from milk inoculated with only lactococci. Cheeses made with a defined-strain starter system consisting of L. lactis subsp. lactis H6 and the bacteriocin-producing culture received the highest scores for flavour intensity and quality.

    Acceleration of flavour formation in cheese by a bacteriocin-producing adjunct lactic culture (1997)
    Springer
    Biotechnology letters 19 (1997), S. 1011-1014

    Notes: Abstract Bacteriocin-producing Enterococcus faecalis INIA 4 was used as adjunct lactic culture at inoculum levels ranging from 0.003% to 0.10% in the manufacture of semi-hard cheese. Cheese made from milk with 0.003% adjunct culture had the most pronounced proteolysis and developed a characteristic cheese flavour faster than the rest, reaching in 30.4 days the flavour intensity score of a 45-day control cheese made without adjunct culture.

    Seismic studies in the Cretan Sea, 2 : the southern Aegean Sea: an extensional marginal basin without sea-floor spreading? ; results of R.V. "Meteor" and R.R.S. "Shackleton" cruises (1977)
    Bornträger
    Details
    Publication Date: 2022-07-22
    Description: This paper is a dcscription of the shallow structure of the Cretan Trough in the Aegean Sea as illustrated by continuous seismic profiles obtained by R. V. "Meteor" (1600 n.m., 1974), and R. R. S. "Shackleton" (1000 n.m., 1972, 1974). Study of this data shows an erosional unconformity between indurated rocks and sediments which over most of the Cretan Trough corresponds to erosion after the main Alpine orogeny and prior to the Upper Tortonian and in some places to the Upper Pliocene transgression. Thick sediments of up to 1.5 km have collected in local basins. Strong vertical movements on normal faults were responsible for the formation of the Cretan Trough and subsequently controlled the sedimentation. Sediments within the Trough have been deformed by Upper Pliocene/Pleistocene faulting and folding. Quaternary intrusions of volcanic? material are sporadically observed over the whole width of the Cretan Trough and do not suggest active seafloor spreading. Extensional processes are seen to be the dominant f eature in the tectonics of this area since ca. 10 m. y. A geodynamic process responsible for the observed structural data - mantle diapirism or subduction induced back-arc spreading - could not be derived from the reflection seismic data.

    CTP1L Endolysin Regulated by a Secondary Translation Product [Protein Structure and Folding] (2016)
    The American Society for Biochemistry and Molecular Biology (ASBMB)
    Details
    Publication Date: 2016-03-05
    Description: Bacteriophages produce endolysins, which lyse the bacterial host cell to release newly produced virions. The timing of lysis is regulated and is thought to involve the activation of a molecular switch. We present a crystal structure of the activated endolysin CTP1L that targets Clostridium tyrobutyricum, consisting of a complex between the full-length protein and an N-terminally truncated C-terminal cell wall binding domain (CBD). The truncated CBD is produced through an internal translation start site within the endolysin gene. Mutants affecting the internal translation site change the oligomeric state of the endolysin and reduce lytic activity. The activity can be modulated by reconstitution of the full-length endolysin-CBD complex with free CBD. The same oligomerization mechanism applies to the CD27L endolysin that targets Clostridium difficile and the CS74L endolysin that targets Clostridium sporogenes. When the CTP1L endolysin gene is introduced into the commensal bacterium Lactococcus lactis, the truncated CBD is also produced, showing that the alternative start codon can be used in other bacterial species. The identification of a translational switch affecting oligomerization presented here has implications for the design of effective endolysins for the treatment of bacterial infections.

    Publication Date: 2014-06-19
    Description: There is overwhelming evidence that ions are present near the vapor–liquid interface of aqueous salt solutions. Charged groups can also be driven to interfaces by attaching them to hydrophobic moieties. Despite their importance in many self-assembly phenomena, how ion–ion interactions are affected by interfaces is not understood. We use molecular...

    Extended surfaces modulate hydrophobic interactions of neighboring solutes [Chemistry] (2011)
    National Academy of Sciences
    Details
    Publication Date: 2011-10-26
    Description: Interfaces are a most common motif in complex systems. To understand how the presence of interfaces affects hydrophobic phenomena, we use molecular simulations and theory to study hydration of solutes at interfaces. The solutes range in size from subnanometer to a few nanometers. The interfaces are self-assembled monolayers with a range of chemistries, from hydrophilic to hydrophobic. We show that the driving force for assembly in the vicinity of a hydrophobic surface is weaker than that in bulk water and decreases with increasing temperature, in contrast to that in the bulk. We explain these distinct features in terms of an interplay between interfacial fluctuations and excluded volume effects—the physics encoded in Lum–Chandler–Weeks theory [Lum K, Chandler D, Weeks JD (1999) J Phys Chem B 103:4570–4577]. Our results suggest a catalytic role for hydrophobic interfaces in the unfolding of proteins, for example, in the interior of chaperonins and in amyloid formation.
