  • Environmental Stress screening some misconceptions
    Journal of Environmental Sciences-china, 2006
    Co-Authors: Duane Pennington
    Abstract:

    Recent shipbuilding contracts and requests for proposals have specified Environmental Stress Screening (ESS) for electronics equipment. As with any new requirement, misconceptions have hindered the implementation of a viable ESS program within the shipbuilding industry. This paper addresses several of these misconceptions to provide an understanding of the objectives and advantages of a cost-effective ESS program applied to the shipbuilding industry.

  • The Impact of Environmental Stress on Bt Crop Performance.
    Trends in plant science, 2020
    Co-Authors: Patricia Sarai Girón-calva, Richard M. Twyman, Ramon Albajes, Angharad M. R. Gatehouse, Paul Christou
    Abstract:

    Bt crops have been grown commercially for more than two decades. They have proven remarkably effective in the control of target insect pests. However, Bt crops can become less effective under various forms of Environmental Stress. Most studies in this area have considered the effect of Environmental Stress on Bt insecticidal protein levels or target pest mortality, but not both, resulting in a lack of mechanistic analysis. In this review, we critically examine previous research addressing the impact of Environmental Stress on the effectiveness of Bt crops. We find that the body of research data is not sufficiently robust to allow the reliable prediction of the performance of Bt crops under extreme climatic conditions.

  • pax3 confers functional heterogeneity in skeletal muscle stem cell responses to Environmental Stress
    Cell Stem Cell, 2019
    Co-Authors: Audrey Der Vartanian, Marie Quetin, Stephanie Michineau, Frederic Aurade, Shinichiro Hayashi, Christelle Dubois
    Abstract:

    Summary Muscle satellite cells (MuSCs) are the quiescent muscle stem cells required for adult skeletal muscle repair. The impact of Environmental Stress such as pollution on MuSC behavior remains unexplored. We evaluated the impact of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) exposure, a ubiquitous and highly toxic pollutant, on MuSCs by combining in vivo mouse molecular genetic models with ex vivo studies. While all MuSCs express the transcription factor PAX7, we show that a subset also express PAX3 and exhibit resistance to Environmental Stress. Upon systemic TCDD treatment, PAX3-negative MuSCs display impaired survival, atypical activation, and sporadic differentiation through xenobiotic aryl hydrocarbon receptor signaling. We further show that PAX3-positive MuSCs become sensitized to Environmental Stress when PAX3 function is impaired and that PAX3-mediated induction of mTORC1 is required for protection. Our study, therefore, identifies a functional heterogeneity of MuSCs in response to Environmental Stress controlled by PAX3.

  • the strain in the test Environmental Stress cracking of plastics
    Polymer Testing, 2003
    Co-Authors: Q G Du, Y Q Li
    Abstract:

    Abstract An investigation was carried out to determine the appropriate values of strain to be exerted in the test for Environmental Stress cracking of different kinds of polymeric materials. It was found that for the brittle plastics the elastic region on the Stress-strain curve is the best selection; for toughened plastics the strain should be selected in the plastic region; for polycarbonate, which can crack easily in a chemical medium, a strain below the yield point is suitable. These results could be used as a reference in the application of test method “Plastics-Determination of Environmental Stress cracking (ESC)-Ball or pin impression method”.

  • a formulation of Environmental Stress testing and screening
    Reliability and Maintainability Symposium, 1994
    Co-Authors: H. Anthony Chan
    Abstract:

    Although hard-defects may be detectable in factory tests, weak products may exhibit failures or degrade only under certain Stress conditions. Without Stress testing, these weak products may often be shipped to customers causing early failures in the field. Early failures usually come from product weaknesses resulting in the presence of weak populations and the lower end of a broad main population for the product strength distribution. The requirements on the product strength distribution are determined by the reliability criteria and by the distribution of the lifetime maximum Stress of the product. Environmental Stress testing (EST), which includes corrective actions, aim at eliminating product weaknesses to achieve robustness. Environmental Stress screening may augment EST, but is applicable only under certain conditions. Its applicability also depends on whether the dominating failure may be stimulated by threshold Stress, cumulative Stresses or their combination. >
