Procesamiento y estudio preliminar de un material compuesto de matriz AlSi₁₀Mg reforzado con nanopartículas de Ti mediante aleado mecánico. por Sánchez Rico, Valentina

“…The results obtained from the wear resistance made in the sintered samples show that with the 5N load there is a greater wear than with the 1N and 3N loads and that the grinding hours and the addition of the NPTsTi have a significant impact in the results. The results of the Vickers hardness show that with the addition of the nano particles and with the sintered one, it decreases; on the other hand, through the SEM and DRX the creation of new phases such as magnesium oxide and titanium oxide was observed in addition to observing some pores in certain microstructures. …”

Inestabilidad cormosómica específica en neoplasia cervical evaluada mediante técnicas de citogenética molecular por García Vielma, Catalina

“…In 2011 was described a process called chromothripsis, which postulates that all rearrangements are generated from a single catastrophic event in the cell with the bonding of the fragments in areas of micro-homology, resulting in the formation of derivative chromosomes. There have been few studies on the subject but found association between chromothripsis and poor prognosis of some diseases, such as multiple myeloma and neuroblastoma. …”
