Computational modelling of the behaviour of biomarker particles of colorectal cancer in fecal matter

Colorectal adenocarcinoma is one of the carcinogenic diseases that is increasing the morbidity and mortality rates worldwide. The disease initially occurs through the segregation of biomarker substances in the human system without manifesting symptoms that affect the health of the carrier. Early detection would allow the application of more effective treatments, less invasive procedures and reduce the development of cancer. The purpose of this investigation was the elaboration of a mathematical model and the development of computational simulations to visualize the behavior of biomarker particles in transit through the colon. The flow conditions, properties of the viscous medium and biological regions of interest were established. Constitutive models, numerical conditions and solution strategies were determined. A numerical grid was used to represent the model of the colon and the human feces that carry the bioparticles (biomarkers). The results indicated the trajectories of the bioparticles in the fecal mass and the interactive movement with the natural contractions of the colon. The analysis of the movement of the biomarker particles can provide future less invasive alternatives for the detection in real time of the cancer by means of the implantation of biosensors in the walls of the colon

Implicaciones del ingreso de Colombia a la OCDE

The Organization for Economic Cooperation and Development (OECD) emerged in the post-war period from the initiative of European leaders, who considered that to achieve a lasting peace the best thing was to “encourage cooperation and recovery, instead of punishing the vanquished”.La Organización para la Cooperación y el Desarrollo Económico (OCDE) surgió en la posguerra por iniciativa de los líderes europeos, quienes consideraron que para alcanzar una paz duradera, lo mejor era “fomentar la cooperación y la recuperación, en vez de castigar a los vencidos”

El plan nacional de desarrollo 2018-2022: “Pacto por Colombia, pacto por la equidad”

The President of the Republic, Iván Duque Márquez, sanctioned the development plan “Pact for Colombia, pact for equity”, established by means of Law 1955 of May 25, 2019. This plan, which will be executed in the four-year period 2018–2022, becomes the road map of public policy and investments during his presidential term.El presidente de la República, Iván Duque Márquez, sancionó el plan de desarrollo “Pacto por Colombia, pacto por la equidad”, establecido por medio de la Ley 1955 del 25 de mayo de 2019. Dicho plan, que se ejecutará en el cuatrienio 2018–2022, se convierte en la hoja de ruta de la política pública y las inversiones durante su período presidencial

El desempleo en Colombia: una aproximación

One of the most pressing issues currently in Colombia is the high unemployment rate. Although, actually, this is not just a problem for the country, because one of the fundamental macroeconomic objectives of any nation is to contain unemployment. While it is true that the level of unemployment must conform to the size and the composition of the economy analyzed, the unemployment rate should not exceed certain levels, because this could undermine political stability.Uno de los problemas más apremiantes actualmente en Colombia es la alta tasa de desempleo. Aunque, en realidad, este no es solo un problema para el país, porque uno de los objetivos macroeconómicos fundamentales de cualquier nación es contener el desempleo. Si bien es cierto que el nivel de desocupación debe ajustarse al tamaño y la composición de la economía analizada, la tasa de desempleo no debe exceder ciertos niveles, porque ello podría atentar contra la estabilidad política

Magnitud e implicaciones de la pobreza en Colombia

Poverty is an important concept in the social sciences and its interpretation generally depends on the school of thought on which it is based. However, most of its scholars consider that poverty is the deprivation or deficiency of a condition or the obtaining of income in relation to a predetermined threshold.La pobreza es un concepto importante en ciencias sociales, cuya interpretación, por lo general, depende de la escuela de pensamiento en la que se sustenta. Sin embargo, la mayoría de sus estudiosos considera que la pobreza es la privación o deficiencia de una condición o la obtención de ingresos con relación a un umbral prefijado

El censo de 2018 y sus implicaciones en Colombia

The national census of population is an essential statistical instrument in any country .It is a basic input so that both the public and private sectors have the relevant information to design their policies in the best way and thus achieve the proposed objectives. In the Colombian case, the census has been the object of many criticisms and objections insofar as, according to the population projections made by the National Department of Statistics (DANE, by its acronym in Spanish), according to the 2005 census, the population calculated was 50 million people;however, the 2018 census found that we are 45 5 00 000, that is, a difference of 9%.El censo nacional de población es un instrumento estadístico esencial en cualquier país. Es un insumo básico para que tanto el sector público como el privado tengan la información pertinente para diseñar sus políticas de la mejor forma y así alcanzar los objetivos propuestos. En el caso colombiano, el censo ha sido objeto de muchas críticas y objeciones en la medida en que, de acuerdo con las proyecciones poblacionales realizadas por el Departamento Nacional de Estadística (DANE), según el censo de 2005, la población calculada era de 50 000 000 de personas; sin embargo, el censo de 2018  encontró que somos 45 500 000, es decir, una diferencia de 9 %
