RESUMENEn el presente documento se introducen y analizan algunas de las variables a tener en cuenta en cualquier estudio de viabilidad referente a la inversión de capital privado de banca colombiana en el sector bancario español, planteando un modelo de negocio que permita alcanzar dicha viabilidad financiera de una forma sostenible mediante un formato de banco colombiano bajo la supervisión del Banco de España. Se plantean, así mismo, los requisitos y regulaciones a cumplir, incluyendo un diagnóstico del entorno económico y de la perspectiva del mercado financiero de captación y colocación bancaria española, así como sus portafolios y estrategias de marketing en un horizonte financiero a cinco años.ABSTRACTIn the present work some of the variables to be considered in any viability study concerning private equity investment of Colombian banks in the Spanish banking sector are introduced and discussed. Further, it proposes a business model that allows sustainable financial viability through a format of Colombian bank under the supervision of the Bank of Spain. Some of the requirements and regulations to comply are likewise explained, including an assessment of the economic environment and financial market perspective of the Spanish bank sector, as well as their portfolios and marketing strategies in a financial horizon to five years.

High Doses

High doses of antimicrobial agents are a huge threat due to the increasing number of pathogenic organisms that are becoming resistant to antimicrobial agents. This resistance has led to a search for alternatives. Therefore, this study presents the synthesis and characterization of ZrO2-Ag2O nanoparticles (NPs) by sol-gel. The NPs were analyzed by dynamic light scattering (DLS), UV-visible (UV-vis), Raman and scanning electron microscopy (SEM). The NPs were later evaluated for their antifungal effects against Candidaalbicans, Candida dubliniensis, Candida glabrata, and Candida tropicalis, using disc diffusion and microdilution methods, followed by the viability study. The DLS showed sizes for ZrO2 76 nm, Ag2O 50 nm, and ZrO2-Ag2O samples between 14 and 42 nm. UV-vis shows an absorption peak at 300 nm for ZrO2 and a broadband for Ag2O NPs. Raman spectra were consistent with factor group analysis predictions. SEM showed spherically shaped NPs. The antifungal activity result suggested that ZrO2-Ag2O NPs were effective against Candida spp. From the viability study, there was no significance difference in viability as a function of time and concentration on human mononuclear cells. This promising result can contribute toward the development of alternative therapies to treat fungal diseases in humans.
