Degradation of 1,4-Dioxane and Cyclic Ethers by an Isolated Fungus [PDF]
Applied and Environmental Microbiology, 2005 ABSTRACT By using 1,4-dioxane as the sole source of carbon, a 1,4-dioxane-degrading microorganism was isolated from soil. The fungus, termed strain A, was able to utilize 1,4-dioxane and many kinds of cyclic ethers as the sole source of carbon and was identified as Cordyceps sinensis from its 18S rRNA gene

Cyclic stress-controlled tests on offshore clay
Journal of Rock Mechanics and Geotechnical Engineering, 2017 One of the main concerns in cyclic behavior of soft clay is gradual degradation with the progression of loading cycle. A series of cyclic constant-volume direct simple shear (CDSS) loading tests was performed on Malaysia offshore clay to study its ...

A Simplified Method for Analysis of Laterally Loaded Piles considering Cyclic Soil Degradation
Advances in Civil Engineering, 2021 This paper proposes a simplified method to analyze the bearing behavior of pile undergoing cyclic lateral load. Firstly, a modified strain model is proposed by utilizing the Duncan–Chang model to describe the stress-strain behavior of soils in the strain

Scientific Reports, 2023 AbstractAgitation is a commonly encountered stress for enzymes during all stages of production and application, but investigations that aim to improve their tolerance using topological engineering have yet to be reported. Here, the plastic-degrading enzyme IsPETase was cyclized in a range of topologies including a cyclic monomer, cyclic dimer and ...

Synergistic degradation of dentin by cyclic stress and buffer agitation [PDF]
Journal of the Mechanical Behavior of Biomedical Materials, 2015 Secondary caries and non-carious lesions develop in regions of stress concentrations and oral fluid movement. The objective of this study was to evaluate the influence of cyclic stress and fluid movement on material loss and subsurface degradation of dentin within an acidic environment.

Dynamic Shear Degradation of Geosynthetic–Soil Interface in Waste Landfill Sites
Applied Sciences, 2017 Geosynthetics and soil particles inevitably come into contact, resulting in a geosynthetic–soil interface. The discontinuity of the materials at the interface causes an intricate shear response, especially under dynamic loads.

Acoustic Entropy of the Materials in the Course of Degradation
Entropy, 2016 We report experimental observations on the evolution of acoustic entropy in the course of cyclic loading as degradation occurs due to fatigue. The measured entropy is a result of the materials’ microstructural changes that occur as degradation due to ...
