Measurement of electromagnetic radiation in the single point incremental forming of AA3003-O

International Journal of Lightweight Materials and Manufacture, 2020
The strength and rigidity of the metals depends upon its crystal structures and intermolecular arrangement which resist its failure during loading. During the plastic deformation it is observed that an electromagnetic radiation (EMR) is emitted when ...

Spif on Polymers – Experimental Data Design and Processing

Acta Universitatis Cibiniensis. Technical Series, 2023
Abstract The paper’s aim is to describe the stages of the experimental research as well as the processing of data measured in the SPIF of some polymeric materials using methods such as the Taguchi method, ANOVA analysis, and establishing the regression equation to determine the relevant factors of influence.

Interaction of preimplantation factor with the global bovine endometrial transcriptome.

PLoS ONE, 2020
Preimplantation factor (PIF) is an embryo derived peptide which exerts an immune modulatory effect on human endometrium, promoting immune tolerance to the embryo whilst maintaining the immune response to invading pathogens.

Research on the Radial Accuracy of Ultrasonic Vibration‐Assisted Single Point Incremental Forming Parts

International Journal of Aerospace Engineering, Volume 2019, Issue 1, 2019., 2019
With the more and more complexity demands of the market, the geometric accuracy of the part has become the main factor restricting the development of single point incremental forming technology (SPIF). For this reason, with the truncated cone as the target part, the radial accuracy error generation mechanism was analyzed from the aspects of sheet ...

Preimplantation factor modulates acute inflammatory responses of equine endometrium

Veterinary Medicine and Science, Volume 4, Issue 4, Page 351-356, November 2018., 2018
Preimplantation factor modulates acute inflammatory responses of equine endometrium. Abstract Persistent mating‐induced endometritis (PMIE) is a significant cause of mare infertility hence its treatment would advance the management of susceptible mares.
