    A short geostatistical study of the three-dimensional spatial structure of fumonisins in stored maize

    No full text
    The heterogeneous three-dimensional spatial distribution of mycotoxins has proven to be one of the main limitations for the design of effective sampling protocols. Current sample collection protocols for mycotoxins have been designed to estimate the mean concentration and fail to characterise the spatial distribution of the mycotoxin concentration due to the aggregation of the incremental samples. Geostatistical techniques have been successfully applied to overcome similar problems in many research areas. However, little work has been developed on the use of geostatistics for the design of sampling protocols for mycotoxins. This paper focuses on the analysis of the two and three-dimensional spatial structure of fumonisins B1 (FB1) and B2 (FB2) in maize in a bulk store using a geostatistical approach and on how results help determine the number and location of incremental samples to be collected. The spatial correlation between FB1 and FB2, as well as between the number of kernels infected and the level of contamination was investigated. For this purpose, a bed of maize was sampled at different depths to generate a unique three-dimensional data set of FB1 and FB2. The analysis found no clear evidence of spatial structure in either the two- dimensional or three-dimensional analyses. The number of Fusarium infected kernels was not a good indicator for the prediction of fumonisin concentration and there was no spatial correlation between the concentrations of the two fumonisins

    RESOLVING THE SURFACE CONTRIBUTION OF THE P L2, 3 VV AUGER LINESHAPE OF GAP(110) VIA USE OF (1 X-1) SB OVERLAYERS

    No full text
    An experimental and theoretical study of the band-like P L2,3VV Auger lineshape for GaP(110) is reported (kinetic energy almost-equal-to 120eV). By deposition of one monolayer of Sb (isoelectronic to P) we determine the surface-related Auger lineshape as the difference between the two spectra measured from the as-cleaved surface and the GaP/Sb interface. Theoretical calculations based on a single particle approach including different structural coordination models (i.e. ideally truncated surface, real relaxed surface, ordered Sb overlayer) are performed, which allows to isolate the surface contribution of the L2,3VV Auger profile from the bulk related lineshape. Moreover the results of the joint analysis are discussed giving excellent agreement between calculations and measurements and pointing toward an interpretation of the P LVV lineshape in terms of surface structural probe

    EXPERIMENTAL AND THEORETICAL SURFACE COMPONENT OF THE PL2,3VV AUGER LINESHAPE IN GAP(110) - THE USE OF ORDERED (1X1) SB OVERLAYERS

    No full text
    An analysis of the theoretical and experimental surface contribution of the PL2,3VV Auger lineshape in GaP(110) is performed. From the theoretical point of view the lineshapes are calculated within a single-particle framework from a slab-by-slab tight-binding calculation of the ideal and real relaxed surfaces. The experimental information is extracted by comparing the Auger feature of as-cleaved GaP(110) and of the GaP(110) interfaced with one ordered monolayer of Sb. This allows the LVV surface component to be isolated. A comparison with theory, showing strong similarities in the position of the surface-related features is discussed

    SURFACE LOCAL DENSITY OF STATES OF INP(110) VIA PL2,3VV AUGER LINESHAPE - THE ROLE OF AN ORDERED (1X1) SB OVERLAYER

    No full text
    An experimental and theoretical investigation on the PL2,3VV Auger lineshape of the InP(110) surface is presented. A band-like picture provides a good description of the spectral features. In addition, deposition of one monolayer of Sb on InP(110) is shown to drive the surface atoms into an environment similar to that present in the bulk, so that a comparison between the PL2,3VV spectrum from the clean and Sb-covered sample allows us to discriminate between the surface contribution and the bulk contribution to this surface-sensitive Auger transition

    ANION-SPECIFIC SURFACE VALENCE-BAND STATES IN HETEROPOLAR SEMICONDUCTORS - THE CASE OF GAP(110) AND INP(110)

    No full text
    The surface- and anion-specific valence-band states of heteropolar P containing III-V semiconductors [GaP(110) and InP(110)] have been determined by analysis of the Auger P L2,3 VV line shape of the ascleaved samples and the well-ordered epitaxial Sb-covered interfaces. The experimental spectra are analyzed in terms of slab-resolved partial density-of-states calculations performed for different surface structural models
