Se presenta el diseño y la factibilidad de un método destinado a la obtención de Cu-64 en un reactor nuclear, a partir de la reacción umbral sobre zinc, inducida por la componente rápida del espectro neutrónico, 64Zn(n,p)64Cu, para su utilización en tomografía por emisión de positrones (PET). Las experiencias preliminares se han realizado en el reactor de investigación RP-10 a una potencia de 3.5 MW, seguidas por una separación radioquímica mediante extracción por solventes, empleando una solución clorofórmica de ditizona. Se ha identificado y cuantificado el radioisótopo obtenido a través del pico de 1345.77 keV de energía, utilizando espectrometría gamma de alta resolución. El rendimiento preliminar alcanzado demuestra la viabilidad del método planteado.

Purpose – This study aims to map the relationship between entrepreneurial orientation (EO), market orientation (MO), and supply chain agility (SCA) from the operations perspective. An analysis of the most relevant manuscripts on the topic supposes a gap in the existing literature; thus, such an analysis was performed to evaluate consensus and discrepancies between scholars. Design/methodology/approach – The literature review includes 13 papers published in Web of Science-indexed journals. These studies provide an overview of MO and EO on SCA. This review uses content analysis to map the nexus between these three capabilities. Findings – The results indicate that the literature can be clustered in four areas: (a) MO and EO with supply chain agility, (b) MO and supply chain agility, (c) EO and supply chain agility, and (d) supply chain orientation and other orientations as a research...

Determina la relación entre las creencias irracionales y el funcionamiento familiar en adolescentes de educación secundaria que asisten a instituciones educativas públicas y privadas en el distrito de Los Olivos, Lima. Para ello, se empleó una metodología no experimental, utilizando un diseño de investigación descriptivo correlacional y comparativa. Se efectuó en una muestra de 395 estudiantes, con edades comprendidas entre 13 a 17 años, tanto hombres como mujeres. La muestra estuvo conformada por 227 estudiantes de una institución educativa pública y 168 de una privada. Se utilizaron dos instrumentos: el Inventario de Creencias Irracionales para Adolescentes (TCI - A) de Cardeñoso y Calvete, y la Escala de Evaluación de la Cohesión y Adaptabilidad Familiar (FACES III) de Olson, modificada a la comunidad peruana por Bazo et al (2016). Se evaluó la validez y la fiabilidad d...

En la ciudad de Arequipa se vienen desempeñando empresas internacionales gastronómicas las cuales ofrecen a las personas que afluyen a sus establecimientos diferentes productos que ofertan con su menú establecido. Gracias al boom gastronómico que vive el país han tratado de satisfacer la necesidad de incorporar en el desarrollo de su gestión a la cultura peruana ofreciendo la opción del menú fusión con productos peruanos de alta calidad. La presente investigación determinará el grado de influencia de la cultura peruana en el desempeño de las empresas internacionales gastronómicas en la ciudad de Arequipa, a través de diferentes procesos como el análisis de aplicación y descripción de los resultados mediante la estadística descriptiva, además del uso de tablas cruzadas. Habiéndose utilizado y desarrollado los instrumentos se encontraron datos precisos que la Cultura Pe...

The objective of this article is to provide recommendations for public policies that guarantee the conditions for effective access to justice, support and protection from the State to prevent and avoid that minor children lose parental care while their parents are serving a custodial liberty measure. The article addresses four points regarding the care of prisoners: a) the enhancement of the legal and jurisprudential framework on the guarantee of rights of persons deprived of liberty in relation to their minor sons and daughters; b) guidelines for the formulation, harmonization and implementation of national public policies around the guarantee of rights of the population in a situation of high vulnerability in prison contexts, through national and territorial development plans, focused on strengthening plans, programs, projects and strategies of comprehensive protection for the families...
