    The microflora of semi-preserved fish products II. The effect of the quality of raw materials, added materials, and storage conditions (1964)
    Springer
    Antonie van Leeuwenhoek 30 (1964), S. 197-208 
    Details
    ISSN: 1572-9699

    Topics: Biology
    Notes: Abstract This paper is concerned with titbits, i.e. canned fish products that have not been subjected to heat, but which have certain keeping qualities thanks to their high salt content, low pH, and the addition of preservatives. The effects of such factors as the raw material used, the composition of the pickle added to the titbits before they are canned, and physical procedures, e.g. freezing and thawing, on the keeping qualities of the titbits have been investigated. The keeping quality varied substantially with the amount of sugar added to the pickle, a high sugar content markedly prolonging and a low sugar content shortening the maximum tolerable duration of storage of the products. Sodium benzoate proved to have a good effect as a preservative, while nisin had no demonstrable antibiotic effect at all. Freezing of canned titbits before storage at 20 C produced some improvement in keeping qualities and seemed to damage some types of bacteria present. In fermented specimens of titbits the microflora was dominated by cocci and lactobacilli. However, the total amount of bacteria initially present in the cans is not directly correlated to the keeping qualities of the product.

    Transient bending waves in anisotropic plates studied by hologram interferometry (1989)

    ISSN: 1741-2765

    Notes: Abstract Propagating bending waves are studied in plates made of glass-fiber reinforced polyester. The waves are generated by the impact of a ballistic pendulum. Hologram interferometry, with a double pulsed ruby laser as light source, is used to record the out of plane motion of the waves. The interferograms have an elliptic-like symmetry for an orthotropic plate, while the wave pattern for a symmetric angle-ply reinforced plate has a symmetry about the axes of reinforcements. Experimental data are compared on one hand to analytical results obtained by assuming that the orthotropic plate can be described as if isotropic along the main axes, and on the other hand to numerical results from calculations using the finite-element method. The effective Young's modulus raised to power 1/4 is shown to be an important parameter for the description of the dispersive wave pattern. A defect in the plate alters the wave pattern in the interferograms significantly. This may have technical use.

    Applications of reciprocity, electronic holography and shearography in statics (1994)
    Springer
    Experimental mechanics 34 (1994), S. 334-339 
    Details
    ISSN: 1741-2765
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract This paper illustrates the use of reciprocity in electronic-holography experiments to determine unknown forces or couples acting on a mechanical structure. Electronic holography and electronic shearography are simple, fast and contact-free methods for the measurement of deformation fields or gradients of deformation fields, both for static and sinusoidal loadings. From a first measurement, the deformation field of the structure for a known force is determined. In a second experiment, the deformation field for the unknown quantity is measured. Reciprocity is then used to determine the unknown quantity. These optical methods are useful tools for the understanding of reciprocity.

    Notes: Abstract Propagating bending waves are studied in plates made of aluminum and wood. The waves are generated by the impact of a ballistic pendulum. Hologram interferometry, with a double pulsed ruby laser as the light source, is used to record the out of plane motion of the waves. Elliptic-like fringes visualize differences in wave speed for different directions in the anisotropic plate and circular ones are obtained for the isotropic plate. The experimental data for the isotropic plate compare favorably with analytical results derived from the Kirchhoff-plate equation with a point impact of finite duration. A similarity variable is found when starting conditions are modeled as a Dirac pulse in space and time, that brings new understanding to the importance of specific parameters for wave propagation in plates. A formal solution is obtained for a point force with an arbitrary time dependence. For times much larger than the contact time, the plate deflection is shown to be identical to that from a Dirac pulse applied at the mean contact time. A method for determining material parameters, and the mean contact time, from the interferograms is hence developed.

    A nondestructive method to determine material properties in orthotropic plates (1987)
    Brookfield, Conn. : Wiley-Blackwell
    Polymer Composites 8 (1987), S. 103-108

    Notes: An electronic speckle pattern interferometer (ESPI) is used to determine modes of vibration in rectangular, orthotropic, free-free plates; that is using a noncontact, nondestructive, optical method. It is shown, using the finite element method (FEM), that each of the first three modes of vibration in rectangular orthotropic plates has a strong dependence upon only one of the main material parameters, namely the in-plane shear modulus and the two Young's moduli, respectively. With this one-variable dependence it is a simple task to determine the effective material parameters. This method has several obvious advantages compared to the use of test bars and it can be extended to give a measure of the damping parameters and probably also be used for production control. Preliminary results are presented and discussed.
