The Mass spectroscopy analysis of some types of Piscos Peruvians and two adulterated samples, prepared by an addition of sugar to the skins and the other by adding sugar-cane alcohol, have reported interesting evidence of a difference in composition at the adulterated samples. They are compounds such as furfural, the acetate and others, which have not been detected in the pisco prepared correctly and what could be attributed as products of the fermentation of sucrose, sugar, which should not be in the musts Grape where there are only fructose and glucose. The developed method allows not only the correct identification of the components of our Pisco, which once established, could be a way that allows to differentiate it from other spirits and pisco adulterated.

The purpose of this study is to know the composition of the fractions of distillates wort for the production of Pisco, two of the main grape varieties for their manufacture: Torontel and broken. The analysis was performed by the method of gas chromatography to follow the standard technique for the analysis of Peruvian Pisco. We analyzed 24 of distillate fractions obtained from two grape must Torontel and shakes, obtained by natural fermentation.The grape shakes presents a greater concentration of higher alcohols that must of torontel, but lesser amount of esters that the latter. The analysis on samples from both distillations, show a decrease in the concentration of higher alcohols and esters passes under the process of distillation, while the concentrations of acetaldehyde and methanol remained virtually constant. Considering the total volume of each fraction analyzed, all components di...

Pisco is produced from fermented grape seven Pisquera grapes. In this second part is reported the composition of pisco. The analysis was performed using the method USAQ-ME-11 by gas chromatography with mass spectroscopy.

El objetivo del presente trabajo es el de conocer la composición de las fracciones de los destilados del mosto para la producción de pisco, de dos de las principales variedades de uva para su fabricación: Torontel y Quebranta. El análisis se realizó por el método de cromatografía de gases siguiendo la Norma Técnica Peruana para el análisis de pisco. Se analizaron 24 fracciones de destilado obtenidas de dos mostos de uva torontel y quebranta, obtenidos por fermentación natural.El mosto de uva quebranta presenta una mayor concentración de alcoholes superiores que el mosto de torontel, pero menor cantidad de ésteres que esta última. Los análisis para las muestras de ambas destilaciones presentan una disminución en la concentración (expresado en mg de compuesto/100 ml de alcohol anhidro) de ésteres y alcoholes superiores conforme transcurre el proceso de destilación, mientr...

El objetivo de la investigación fue determinar la relación entre clima educacional y bienestar psicológico de los internos de un hospital público de Lima-Perú, 2022. Metodología: Es un estudio de tipo básico, de diseño no experimental, correlacional, corte transversal y enfoque cuantitativo, estuvo conformados por 70 internos de un hospital público de Lima. Se aplicó dos cuestionarios debidamente validados, para la confiabilidad se utilizaron el Alfa Cronbach con un nivel de confiablidad de 0.91 para la variable clima educacional, y 0.69 para la variable bienestar psicológico. Resultados: A nivel descriptivo se observa que el 50% de los internos tienen alto nivel de clima educacional y el 30% bajo nivel, en la variable de bienestar psicológico el 49% de los estudiantes evidencio alto nivel y el 28% bajo nivel. En el análisis diferencial se evidencia que la variable clima edu...

El presente estudio tiene como propósito determinar la relación del control interno con la gestión contable en la Junta de Usuarios del Sector Hidráulico Menor Jaén, San Ignacio, 2021, con una metodología de tipo aplicada, enfoque mixto, diseño no experimental, corte transversal y de nivel descriptivo – correlacional. La población estuvo conformada por 18 colaboradores de todas las áreas, incluyendo al consejo directivo de la institución y como muestra 15 colaboradores que fueron seleccionados por el método de exclusión. Para recoger los datos, se realizó un cuestionario de 34 preguntas, dividido en 18 preguntas control interno y 16 preguntas gestión contable, de acuerdo a la escala de Likert, el cual fue validado a través del juicio de expertos, por medio de la validez de Aiken, obteniendo un coeficiente de 99% de validez. Así mismo, se aplicó el coeficiente alfa de C...

Manejo de Información, Comprensión, Espacio Temporal, juicio crítico.

El uso de la declaración previa para evidenciar contradicción en juicio es una herramienta de la litigación que permite desacreditar al testigo o perito que cambia su versión ofrecida en la fase de investigación preparatoria, lo que impacta en su credibilidad ante los ojos del juzgador. Si bien esta institución no encuentra mayor inconveniente pues la habilita el art.378.6 CPP, el problema surge cuando este criterio es aplicado a lo vertido por el acusado. Un sector se opone a su uso en este supuesto, pues -se sostiene- afecta el principio de no autoincriminación y la naturaleza de la declaración del acusado. Sin embargo, otro sector discrepa, ya que sostiene que no afecta el derecho mencionado ni aquellos que informan el debido proceso, entre otros argumentos. Es así que, a través del Acuerdo Plenario N° 3-2018/SPN, la Sala Penal Nacional, zanjando este asunto, concluyó que ...

Pd-Fe bimetallic catalysts were studied on different supports such as Al2O3, SiO2, C, TiO2 and MgO, which were prepared by the impregnation method at a ratio of 2/1 of Pd/Fe. The characterization was performed by XRD, DTP of hydrogen, TPR, BET and TEM. The results show a high surface area, high dispersion of metals with small crystals and the presence of two types of acid centers.
