Numerical simulation of the influence of blasting vibration on buried oil pipeline
You-qi chuyun, 2021 In order to ensure the safety of buried oil pipelines during blasting construction, the impact of blasting vibration on pipelines was simulated with the ANSYS/LS-DYNA fluid-solid coupling method in combination with the earthwork blasting of Shugang ...

Molecular Oncology, EarlyView.Interferon type 1 (IFN‐1) production and signaling is associated with the acquisition of therapy resistance, following chronic DNA damage, via Interferon‐related DNA damage resistance signature (IRDS) gene expression. An alternative, DNA damage‐independent role of sustained IFN‐1 mediated resistance was identified and characterized by the emergence of ...

Mechanical response and failure pressure prediction of cracked PVC-UH buried thin-walled pipes
Case Studies in Construction MaterialsHigh-performance unplasticized polyvinyl chloride (PVC-UH) buried water supply pipelines may develop cracks during service. It is essential to understand their mechanical response to loads during construction and service, identifying the parameters most ...

Strain monitoring of crossing-fault pipelines with coaxial cable FabryPerot interferometer sensors
You-qi chuyun, 2021 Affected by the extreme geological hazards such as the fault and uneven ground settlement, pipelines are prone to produce large deformations. However, the large strain monitoring cannot be achieved with the existing strain sensing technology due to its ...

Uplift Resistance of Buried Pipelines in Sand
Soils and Foundations, 1994 ABSTRACT A centrifugal model study into the influence of pipe diameter, depth of burial and backfill density on the resistance to uplift of pipes in sand is reported. No significant differences between the behaviour of buried pipes and that of strip anchors is found, justifying the application of anchor uplift theory to buried pipeline behaviour ...

Molecular Oncology, EarlyView.Tumour heterogeneity and clonal evolution of metastatic salivary gland cancer were evaluated in two patients with adenoid carcinoma and one patient with myoepithelial carcinoma. Radiology‐guided autopsy enabled multi‐region sampling (total samples n = 149), followed by whole‐genome sequencing and phylogenetic reconstruction (17 tumour samples, 4–7 per ...

Experimental Research of Buried Pipelines
Procedia Engineering, 2012 AbstractIn structural engineering, is very often needed to monitor the tension in the structures by various reconstructions. Measurement of strain is used by the analysis of additional load effects on structures that were not designed. Particularly challenging is the task in the field, where the measuring system is exposed to extreme conditions that ...

FEBS Open Bio, EarlyView.This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.
