    The objective of the research was to evaluate the use of alternative rations for feeding guinea pigs in the growth-fattening stages. The experimental units were made up of a total of 80 guinea pigs, 40 males and 40 females. A completely random design was applied in a combinatorial arrangement of factors, where factor A: alternative rations had 4 levels and factor B: sex had 2 levels (males and females), and carrying out the evaluation of different variables such as initial weight, final weight, weight gain, total feed intake, feed conversion, carcass weight, carcass yield, all this in addition to the mortality variable, these measurements had an evaluation period of 75 days, the same as the investigation lasted. For the statistical analysis, the experimental results were subjected to an analysis of Variance (ADEVA) and separation of means according to Tukey’s methodology at a significance level (P ≤ 0.05), resulting in significant differences in the feed conversion variable. While for the rest of the variables we found highly significant differences. It was concluded that the best treatment is that of the male guinea pigs that were fed with T2 since they contribute to improving the feed conversion rates without affecting the productive behavior of the livestock. As per the results obtained from this investigation, it is recommended to disseminate to small and medium producers of guinea pigs.

Las unidades experimentales estuvieron conformadas por un total de 80 cuyes de los cuales 40 fueron machos y 40 hembras. Se aplicó un diseño completamente al azar, en arreglo combinatorio de factores, donde el factor A: raciones alternativas teniendo 4 niveles y el factor B: sexo con 2 niveles (machos y hembras), y llevándose a cabo la evaluación de diferentes variables como son: peso inicial, peso final ganancia de peso, consumo total de alimento, conversión alimenticia, peso a la canal, rendimiento a la canal todo esto en y la variable mortalidad, estas mediciones tuvieron un periodo de evaluación de 75 días mismos que duro la investigación. Para el análisis estadístico los resultados experimentales fueron sometidos a un análisis de Varianza (ADEVA) y separación de medias de acuerdo a la metodología de Tukey a un nivel de significancia (P≤0,05) dando como resultado diferencias significativas en la variable conversión alimenticia mientras que para el resto de variables encontramos diferencias altamente significativas. Se concluye que el mejor tratamiento es el de los cuyes machos que fueron alimentados con T2 ya que contribuyen a mejorar los índices de conversión alimenticia sin afectar el comportamiento productivo de los semovientes. Se recomienda difundir a pequeños y medianos productores de cuyes, los resultados obtenidos de la presente investigación.

    La presente investigación tuvo como objetivo, analizar el régimen de facturación ecuatoriano, esencialmente el uso de los comprobantes de venta en las transacciones de los contribuyentes y como se relaciona con las tipologías de evasión tributaria o fiscal que hacen que el contribuyente pague menos impuestos al incluir gastos inexistentes u omisión de ingresos en las declaraciones, perjudicando al Estado ya que reciba menos recursos y realice mayores controles, se estudia el avance tecnológico en el régimen de facturación impulsado por la Administración Tributaria resaltando las mejoras y analizando las falencia que aportan a las variables. Además se estudia la normativa tributaria vigente que se relacionan con el tema y su constante evolución desde el 2008 año en el cual el sistema tributario incluye mecanismos para evitar la evasión fiscal y la defraudación tributaria como un delito, se hace además un análisis del proyecto de control emblemático de empresas fantasmas y los resultados obtenidos por el SRI en donde se evidencia la importancia de las variables de estudio, su aplicación práctica y la incidencia en la recaudación tributaria, el enfoque de la investigación es cualitativa y cuantitativa ya que se analiza por qué los contribuyente evaden sus impuestos y los datos estadístico obtenidos de la información disponible y solicitada al SRI, utilizando una investigación de campo al realizar entrevistas a funcionarios del SRI de los departamentos de control tributario que son las personas que detectan el mal uso de comprobantes de venta e investigación bibliográfica revisando leyes y estudios relacionados a la presente investigación, estableciendo sectores de mayor riesgo de evasión e identificando las causas principales del problema de estudio como son: el desconocimiento del sistema tributario, asesoramiento que reciben los ciudadanos para disminuir el pago de sus impuestos e incluso la dificultad de cumplir las obligaciones tributarias puesto que el sistema es complejo. The objective of this research was to analyze the Ecuadorian billing system, essentially the use of sales receipts in the taxpayers’ transactions and how it relates to tax evasion or tax evasion typologies that cause the taxpayer to pay less taxes when including non-existent expenses or omission of income in the declarations, harming the State and receiving less resources and carrying out greater controls, technological progress is studied in the billing regime promoted by the Tax Administration highlighting the improvements and analyzing the failures they bring to the variables. In addition, the current tax regulations related to the subject and its constant evolution since 2008 are studied, in which the tax system includes mechanisms to avoid tax evasion and tax fraud as a crime, and an analysis of the project is made. emblematic control of ghost companies and the results obtained by the SRI in which the importance of the study variables, their practical application and the incidence on tax collection are evidenced, the research focus is qualitative and quantitative since it is analyzed why the taxpayers evade their taxes and the statistical data obtained from the information available and requested from the SRI, using a field investigation when conducting interviews with SRI officials from the tax control departments who are the people who detect the misuse of sales receipts and bibliographic research reviewing laws and related studies This study is based on establishing sectors at greater risk of evasion and identifying the main causes of the study problem, such as: ignorance of the tax system, advice received by citizens to reduce their tax payments, and even the difficulty of complying with the tax obligations since the system is complex.

    El presente artículo es un análisis retrospectivo y prospectivo  sobre  la aplicación del Diseño Curricular por Competencias en la carrera de Ingeniería Industrial. Se parte de un análisis de: los planteamientos de la Comunidad Europea y el Proyecto Tunning en América Latina sobre la educación superior; estudios realizados sobre el Diseño Curricular por Competencias por diferentes autores en cuanto a sus características y  fines de su aplicación en la educación superior, para luego evidenciar la propuesta curricular de la carrera de Ingeniería Industrial de la Universidad Laica Eloy Alfaro de Manabí del Ecuador y con un análisis de las ventajas y desventajas que tiene este modelo curricular en la carrera. Se abordan los elementos esenciales que permiten  evidenciar que el modelo solo se centra en la empleabilidad del profesional y que tiene limitaciones en cuanto al emprendimiento, investigación, innovación y desarrollo empresarial, elementos que si  han sido considerados en el diseño curricular de la carrera, ya que en este sentido, existe la necesidad de relacionar la universidad, con el mercado laboral y las competencias que expresan la aparente diversidad que se encuentra en las exigencias y en las demandas que tiene en la actualidad la Universidad para que el profesional que egresa sea actor preponderante en su desarrollo profesional y de la sociedad

    Cerebral white matter consists mainly of axons surrounded by myelin sheaths, which are grouped to form association, commissural, and projection fasciculi. The aim of our work was to quantify and compare under the microscope the axons of the white matter association fasciculi in the cerebral hemispheres of cow (Bos taurus), pig (Sus scrofa domesticus) and rabbit (Oryctolagus cuniculus) indirectly by identification of their myelin sheaths. The samples were taken from 30 cerebral hemispheres: 10 cow, 10 pig and 10 rabbit (15 right and 15 left). They were obtained following a protocol based on the Talairach-Tournoux coordinate system for human and primate brains. The slides were stained with Luxol Fast Blue, observed by optical microscopy, and photographed at 600x. Samples were also prepared for observation in scanning transmission electron microscopy (STEM) with osmium tetroxide. The myelin sheaths/axons were counted with the ImageJ software. Statistically significant differences in the number of myelin sheaths per 410 µm2 were found in the inferior and superior longitudinal fasciculi between the left and right hemispheres of cows, with predominance of the right hemisphere; and in the inferior occipitofrontal fasciculus of the rabbit with predominance of the left hemisphere. The use of animal models for experiments in the cerebral fasciculi, especially pig, could give us a greater understanding of the behavior of demyelinating and neurodegenerative diseases in humans
