  • analytical modeling of transient hygro elastic stress Concentration Application to embedded optical fiber in a non uniform transient strain field
    Composites Science and Technology, 2006
    Co-Authors: Frederic Jacquemin, Sylvain Freour, Ronald Guillén
    Abstract:

    The aim of this work is to propose an analytical model for transient hygro-elastic stresses in transversely isotropic multi-layered cylinders. This approach allows one to calculate the time and space dependent hygro-elastic stresses in fiber-reinforced composite submitted to hygroscopic fields by applying the classical continuum mechanics formalism. Application of the proposed model to the case of an embedded optical fiber shows interesting results, concerning the stress field perturbation occurring in the composite in the vicinity of the intrusive optical fiber. The model proposed in this study provides a detailed stress analysis of the inclusion which is required to correctly interpret the data collected through the optical fiber and deduce stresses experienced by the host material.

  • Efficacy of selected pesticides against Tyrophagus putrescentiae (Schrank): influences of applied Concentration, Application substrate, and residual activity over time
    Journal of Pest Science, 2017
    Co-Authors: Salehe Abbar, M. W. Schilling, R. Jeff Whitworth, Thomas W. Phillips
    Abstract:

    Dry-cured ham is protected from arthropod infestations using the fumigant methyl bromide. Tyrophagus putrescentiae (Schrank), known as the cheese or ham mite, decreases the quality and quantity of dry-cured hams during the aging process and is a serious economic threat to dry-cured ham companies. Methyl bromide is a strong ozone-depleting substance that is scheduled to be phased out from most uses in the near future. Consequently, developing effective, feasible, and economic alternatives to methyl bromide is the main purpose of the current project. More than ten registered residual pesticides were assessed for toxicity with glass vials treated with different Concentrations. Twenty mites were transferred to each vial for 24 h of exposure on contact. Persistence of three of these residual pesticides was evaluated over a 2-month period by applying the recommended label rates to different surfaces. Results indicated that the commercial products of deltamethrin plus chlorpyrifos-methyl, chlorphenapyr, and malathion showed promising results for contact toxicity against mites, and chlorphenapyr was highly effective at very low Concentrations. Chlorphenapyr was the only pesticide applied to metal, concrete, and wood that was effective at controlling ham mites for 8 weeks. These pesticides are currently registered for use in similar contexts, so they could be considered as new potential control measures for ham mites in ham plants.
