The technology of thermal welding of the circulation piping of NPPS containing the influence of ultrasound

open access: yesNuclear Energy and Technology, 2017
The authors propose a thermal welding technology with ultrasound treatment for NPP circulation pipe-lines. This technology can significantly increase the strength of welded connections by reducing residual stresses, grain size and welded joint degassing.

Heat affected zone in surfacing chromium ledeburitic steel [PDF]

open access: yesMetalurgija, 2010
Tools get failured during work; wear is a major factor that contributes to failures. Damaged tools are replaced or filed. This paper describes typical changes that occur in the heat affected zone of tool (HAZ), which was repaired by surfacing with a TIG ...

Effect of cerium on welding performance of 700 MPa high-strength steel used in construction machinery

open access: yes工程科学学报, 2020
As the use of high-strength thick plates is increasing in marine engineering, bridge engineering, petroleum pipelines, and other fields, the required performance level of thick welded plates is also increasing.

Effects of high frequency current in welding aluminum alloy 6061 [PDF]

open access: yes, 1968
Uncontrolled high frequency current causes cracking in the heat-affected zone of aluminum alloy 6061 weldments during tungsten inert gas ac welding. Cracking developed when an improperly adjusted superimposed high frequency current was agitating the ...

P‐glycoprotein modulates the fluidity gradient of the plasma membrane of multidrug resistant CHO cells

open access: yesFEBS Letters, EarlyView.
To explore the impact of the overexpression of the multidrug‐transporter P‐glycoprotein (ABCB1) on membrane fluidity, we compared the transversal gradient of mobility and microviscosity in plasma membranes of drug‐sensitive Chinese hamster ovary cells (AuxB1) and their multidrug‐resistant derivatives (B30) using the fluorescent n‐(9‐anthroyloxy) fatty ...

Effect of Grit Blasting and Thermal Spraying on Microstructure Evolution of P91 Weldment [PDF]

open access: yesArchives of Metallurgy and Materials, 2018
In the present work, studies have been carried out on the variations in the microstructure and hardness of P91 base-metal and welded joint. This variations result from the grit blasting and thermal cycle experienced during the thermal spraying process ...

Critical Assessment of the Electric Effect in Electric Arc Welding

open access: yesMetals, 2021
This work provides a critical assessment of electric effects on the microstructure evolution at the heat-affected zone in electric arc welding. Electric effects are the interactions between electromagnetic fields and materials’ microstructures.

Targeting the MDM2‐MDM4 interaction interface reveals an otherwise therapeutically active wild‐type p53 in colorectal cancer

open access: yesMolecular Oncology, EarlyView.
This study investigates an alternative approach to reactivating the oncosuppressor p53 in cancer. A short peptide targeting the association of the two p53 inhibitors, MDM2 and MDM4, induces an otherwise therapeutically active p53 with unique features that promote cell death and potentially reduce toxicity towards proliferating nontumor cells.

Comparing self‐reported race and genetic ancestry for identifying potential differentially methylated sites in endometrial cancer: insights from African ancestry proportions using machine learning models

open access: yesMolecular Oncology, EarlyView.
Integrating ancestry, differential methylation analysis, and machine learning, we identified robust epigenetic signature genes (ESGs) and Core‐ESGs in Black and White women with endometrial cancer. Core‐ESGs (namely APOBEC1 and PLEKHG5) methylation levels were significantly associated with survival, with tumors from high African ancestry (THA) showing ...
