According to various studies, it has been found that due to the lack of reagents for the RT-p.R test for the accurate diagnosis of SARS-CoV-2 infection, tomograp.y began to be used as a criterion to achieve diagnostic sup.ort in p.tients with lack of a definitive diagnosis. The objective of this work is to describe the tomograp.ic findings in p.tients with COVID-19 and their relationship.with the clinical p.esentation in each of the radiological p.tterns. According to the Feinstein Criteria, the analytical typ. of study, with quantifiable, non-exp.rimental data, was cross-sectional from October 2020 to June 2021, obtaining a samp.e of 227 p.tients hosp.talized in the UAER of the CMJp.. Statistical analysis was p.rformed using Microsoft Excel (2021) and Sp.S. According to the radiological classifications, 6.17% (14) p.esented in the Initial (early) p.ase of the disease, 46.7% (106) were in p.ogression and 47.14% (107) in the advanced p.ase of the latter with a higher p.rcentage in the CORADS classification at level 3 with 74.5% in both;Similarly, in advanced onset, the extension with the greatest p.esentation was severe with 86.96% (93). Tomograp.ic studies p.ayed an imp.rtant role during the COVID-19 p.ndemic, together with the ap.lication of international classifications such as CO-RADS and the classification issued by INER, being considered diagnostic sup.ort tools for COVID-19 and p.tient evolution.

Strain engineering,as a p.werful strategy to tune the op.ical and electrical p.op.rties of two-dimensional(2D)materials by deforming their crystal lattice,has attracted significant interest in recent years.2D materials can sustain ultra-high strains,even up.to 10%,due to the lack of dangling bonds on their surface,making them ideal brittle *** remarkable mechanical resilience,together with a strong strain-tunable band structure,endows 2D materials with a broad op.ical and electrical resp.nse up.n ***,strain engineering based on 2D materials is restricted by their nanoscale and strain quantification *** this study,we have modified a homebuilt three-p.ints bending ap.aratus to transform it into a four-p.ints bending ap.aratus that allows for the ap.lication of both comp.essive and tensile strains on 2D *** ap.roach allows for the efficient and rep.oducible construction of a strain system and minimizes the buckling effect caused by the van der Waals interaction by adamantane encap.ulation *** results demonstrate the feasibility of introducing comp.essive strain on 2D materials and the p.tential for tuning their op.ical and p.ysical p.op.rties through this ap.roach.
