La cultura organizacional es conocida universalmente como el conjunto de significados compartidos y creencias en poder de una colectividad; su estudio evidenciará la forma como trabajan las empresas y las conductas que sus miembros toman al enfrentarse a diferentes situaciones. El presente artículo acerca al lector al concepto de cultura organizacional a partir de autores destacados en la historia, y registra el progreso cronológico en los métodos de medición, iniciando desde la observación y análisis psicológico hasta la elaboración de instrumentos especializados que midan el comportamiento de las personas y su influencia en la organización. Todo esto, con el fin de respaldar el avance científico regional, al considerar diversos estudios como precedente para futuras investigaciones.Organizational culture is known universally as the set of shared meanings and beliefs held by a community. The study of Organizational culture will reveal the way of how factories operate and the stance that they take whendealing with different situations. This article presents to the reader with the concept of organizational culture from the best known authors throughout history; furthermore it provides the chronological progress in measurement methods, starting from observation and psychological analysis of the concept, to the preparation of specialized tools to measure people’ behavior and its influence on the organization. All this, in order to support regional scientific progress, on considering several studies as a precedent for future research

Propylene glycol, also known as 1,2 propanediol, is one of the most important chemicals in the industry. It is a water-soluble liquid, considered by the U.S. Food and Drug Administration as safe to manufacture consumer products, including foodstuffs, medicines, and cosmetics. This chemical has essential properties, such as solvent, moisturizer, or antifreeze, in addition to a low level of toxicity. This paper aims to present the selection, simulation, and dimensioning of a trickle bed reactor at a laboratory scale. The sizing was validated with other authors. Two predictive models have been considered for reactor modeling, intrinsic kinetics and coupled intrinsic kinetics, along with mass transfer equations and the wetting of the catalyst particles. The model was implemented using Aspen Custom Modeler® (20 Crosby Dr. Bedford, MA 01730, EE. UU.) to study the reactor behavior in terms of conversion. The results show the profiles of different variables throughout the reactor and present higher glycerol conversion when mass transfer is added to the model.
