    Sulla stima di macro, micro e nano-durezza di materiali metallici mediante analisi elasto-plastiche agli elementi finiti by Luca Susmel, David Taylor

    Published 2011-12-01
    “…Il lavoro sintetizzato nel presente articolo si pone come obiettivo primario quello di investigare lapossibilita di stimare, mediante un approccio elasto-plastico agli elementi finiti, la durezza dei materiali metalliciconvenzionali, e questo sia a livello macroscopico, che a livello microscopico, che, infine, a livello nanoscopico.Per verificare validita e accuratezza della metodologia FEM sviluppata, sono state condotte una serie di analisisperimentali su tre materiali metallici aventi caratteristiche metallurgiche estremamente diverse: una legadfalluminio (Al 7075-T6), un acciaio a basso tenore di carbonio (BS970-En3B) e, infine, un acciaio austenitico(AISI 316L). …”

    Sunitinib Reduced the Migration of Ectopic Endometrial Cells via p-VEGFR-PI3K-AKT-YBX1-Snail Signaling Pathway by Xiaodan Fan, Yanyan Tong, Yiting Chen, Yichen Chen

    Published 2022-01-01
    “…The ectopic endometrial cells from patients were divided into two groups: the control group and the sunitinib group. Co-IP and protein spectrum assay were employed to filtrate differential proteins between two groups, and then, our study discovered a signaling pathway, p-VEGFR-PI3K-AKT-YBX1-Snail, in the cell of EMs. …”

    Surface Hardening of Ti-15V-3Al-3Cr-3Sn Alloy after Cyclic Hydrogenation and Subsequent Solution Treatment by Chia-Po Hung, Tair-I Wu, Jiann-Kuo Wu

    Published 2014-01-01
    “…The as-received and preheated (1000°C-30 min. and 500°C-30 min.) sheets of Ti-15V-3Al-3Cr-3Sn alloy (Ti-153) were treated according to the predetermined process including a cyclic electrolytic hydrogenation (at 50mA/cm2 for 1hr and at 5mA/cm2 for 10 hrs) combining a subsequent solution treatment to see the effects of various operating parameters on the evolution of microstructure and the variations of hardness. …”
