One is as old as the discovery of the Americas, empirical observation refers to the custom of the Andean Indians chew coca leaves (Erythroxilon coca) in order to prevent hunger and avoid fatigue. It is difficult to consider this interesting fact from an experimental point of view, since the physiological mechanisms related to the phenomena of hunger and fatigue are complicated. Cocaine, the active ingredient of coca leaves (Gardekem 1855), is probably the substance responsible for the effects noted.

Este trabajo de suficiencia profesional aborda la problemática presente en la organización Capacidad-Creatividad-Cumplimiento S.A.C. (CCC), una empresa peruana del sector "Otros servicios" orientados a otras empresas (B2B). Se realizó un diagnóstico integral de su situación actual, tanto externo como interno, empleando herramientas como las matrices EFE y EFI, la cadena de valor y el análisis FODA. Como resultado, se identificó la necesidad de optimizar la gestión de la cadena de mando para alinear a la empresa con el cumplimiento de sus objetivos estratégicos. Con base en estos hallazgos, se proponen alternativas para mejorar la eficiencia operativa, incluyendo la diversificación de clientes y el fortalecimiento de relaciones comerciales. Se concluye que la implementación de un marco estratégico que optimice los recursos es la opción más recomendable para mejorar su produc...

Contamination by non-biodegradable solid waste is worrying, mainly due to PET and glass waste, because they are used for single use such as bottles or containers. In addition, global production in 2021 of these materials was 139 million tons and 23.4 million tons, respectively. Therefore, the objective of this research is to develop an efficient design of bricks composed of cement, PET plastic and glass, evaluating both their physical properties and their mechanical properties to reduce said waste. For this, 4 mixtures based on cement, sand and glass were designed with proportions of 1:2:0.5 and 1:2:1. In addition, 5% and 10% PET were incorporated into these proportions. It should be noted that the PET was ground to a size of 0.2 cm and the glass was ground to a size of 2 cm. The tests carried out show that the 1:2:0.5 dosage with 10% PET is the most efficient, since it obtained a compre...

The ever-growing global production of glass generates high waste percentages, the vast majority of which does not get recycled hence increasing the concern on its environmental impact. Studies on the pozzolanic properties of glass powder emerged as a solution to the abundance of waste glass powder available and its insufficient recycling. The aim of this study is to investigate the influence 10%,15% and 20% of waste soda-lime glass powder as partial cement replacement; fresh concrete tests were carried out, as well as compression strength tests at 28 days on grade 280 kg/cm2 concrete produced with pozzolanic cement. Tests results show an insignificant reduction of slump on the concrete mixes, an increase of air content and a decrease in density and compressive strength resistance with increasing glass powder substitution.

The low resistance to compression and flexural of conventional earth techniques such as adobe in the occurrence of earthquakes causes the immediate collapse or failure of structures built with this material. These deficiencies are caused by the lack of stabilization and reinforcement processes of the block, which causes low mechanical performance in the face of seismic forces. The most common structures to collapse during earthquakes in developing countries such as Peru are the self-built adobe rural houses, being the most used in these areas due to the high housing deficit and the high demand for low-cost housing. One solution to this problem is the use of reinforced CEB in rural housing. In the present investigation some properties such as absorption, compressive strength and flexural strength are studied, the results indicate that the compressive strength and flexural strength increas...

During recent years, the rapid growth of the population in urban areas has promoted the development of housing, roads, shopping centres and industries; having increased the consumption of tap water in the concrete industry. A solution to this problem, is to use domestic wastewater treated, due to the large quantities produced and the need to include them within the life cycle of the water; thus bridging the gap of service in urban and rural areas. The present research seeks to use the domestic wastewater treated in the production of concrete for construction; the results show slightly for the slump, initial setting time and splitting tensile increase, and that the resistance to compression and flexural is decreased.

En el presente trabajo se ejecutó un plan de negocio que consiste en la elaboración de un shampoo en barra hecho a base de insumos peruanos. Para realizarlo exitosamente, se efectuó inicialmente una investigación exhaustiva para elegir el sector en el cual nos desempeñamos y a nuestro público objetivo. Con el objetivo de conocer y validar el modelo de negocio se desarrollaron distintas hipótesis que finalmente llevaron a experimentos como el Producto Mínimo Viable (MVP). En base a los MVP’s se realizaron cambios y mejoras en el producto final para que sea del agrado de los clientes y posteriormente motivarlo a efectuar una compra. En este paso, se realizó un ajuste en cuanto a las edades y nivel socioeconómico para alcanzar mayor demanda. Este trabajo contiene distintos presupuestos que se efectuarán a lo largo del proyecto tales como plan de operaciones, marketing, recursos...
