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.

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 ...

Hole-flanging of AA7075-O sheets: conventional process versus SPIF
Procedia Manufacturing, 2020 Incluída en nº 50 Procedia Manufacturing Recently, the research interest in hole-flanging for small and medium-sized batches has turned from conventional press-working to SPIF due to the advantages of incremental forming, such as flexibility and cost of tools. Both technologies have been studied separately using different approaches

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 ...
