The origins of Western medicine are located on the island of Cos, small Greek territory to neighboring Asia Minor. It ruled out any medicine that divine influence in explaining the disease and its causes rather sought natural disorders developed. His concepts were developed in different works written in the V and IV centuries BC; these works had considerable influence in Greece and the ancient world. The most famous physician of this school was Hippocrates, who was born on the island mentioned in 460 BC, but from whom there is little reliable information, much of which is based on a biography written by Soranus. Greek physician who lived in the second century after Christ. Hippocrates lived no doubt it is directly mentioned by Plato in his Dialogues PROTAG pray and Phaedrus and Aristotle's Politics.

There have been 4 cases of patent ductus arteriosus in which calcification of the ductus region on the image plate was observed. The radiographic image feature corresponds to a calcium deposit in the aortic walls next to the aortic opening of the ductus . This area has been identified as the aortic infundibulum . In a review of published cases of patent ductus arteriosus with calcifications recognized at autopsy or x-rays, it was observed that the age of the patients was distributed from 29 to 79. Calcification occurred in cases with and without pulmonary hypertension, although the former were in the majority. The finding of calcification feature helps in the diagnosis of patent ductus arteriosus with pulmonary hypertension , especially in the differential diagnosis between patent ductus with reversed shunt and large VSD with left to right shunt ( Eisenmanger complex ) , whose manifestat...

El presente trabajo investigación tiene como objetivo evaluar el método más eficiente para la medición de resistencia en sistemas de puesta a tierra de grandes dimensiones, en términos de confiabilidad de los resultados, costos y tiempo empleado para su ejecución, considerando que para las mediciones de resistencia no siempre se cuenta con las distancias recomendadas por el método convencional. Se tiene como casos de estudio dos sistemas de puesta a tierra de grandes dimensiones, en el primer sistema se tienen restricciones de distancia para la ejecución de las mediciones y en el segundo no existen restricciones de distancia permitiendo realizar las mediciones a longitudes mayores a cinco veces la longitud más larga de sistema, en ambos casos se aplica y evalúa la eficiencia del método convencional IEEE de medición de resistencia por caída de potencial al 62% y el método al...

El objetivo de la investigación fue determinar la evolución de las exportaciones de banano orgánico al mercado de los Países Bajos en el periodo 2009 – 2015. La idea ha sido demostrar que la exportación de banano orgánico al mercado de los Países Bajos 2009-2015 ha tenido una tendencia positiva, para lo cual hemos utilizado el método estadístico, que consistió en organizar los datos (a través de cuadros), presentar los datos (a través de gráficos de líneas) y describir los datos (a través de números estadísticos como la línea de tendencia y el coeficiente de determinación correspondiente). La principal conclusión a la que se ha llegado es que de acuerdo con los resultados de la investigación el volumen de exportación de banano orgánico al mercado de los Países Bajos en el periodo 2009-2015 ha tenido una tendencia positiva.

El presente trabajo de investigación nace ante la necesidad de contribuir con el desarrollo sostenible en el país, fomentando el uso eficiente de energías limpias como es el caso del aprovechamiento de la energía solar que al ser aprovechada no emite ningún contaminante que afecte al medio ambiente como es el caso de los combustibles convencionales (diésel, gasolina, carbón, etc.). Se obtuvo Agua Caliente Sanitaria (ACS) mediante el uso de colectores solares de placa plana en la institución Educativa Cristiana Bereshi de Chimbote, se realizó el diseño y dimensionamiento de dos sistemas de colectores para abastecer con ACS a una demanda de 40 los alumnos de nivel de educación inicial cada sistema, además se evaluó la viabilidad económica de construir o comprar donde la opción más conveniente fue la de construir ahorrando S/. 1212.35 por sistema. Luego de ser construidas se...

Agricultural producers base their decisions on unofficial information or on their own experience, and despite the fact that there is a state regulator in charge of collecting data on agricultural production, not all producers have access to this information. This article deals with the benefits of implementing a business intelligence system in crop management for agricultural production. This is a quasi-experimental investigation where the data obtained by the La Libertad Regional Agriculture Management and the survey, carried out with agricultural producers in the province of Otuzco, were used as data collection techniques. To prepare of the Business Intelligence System, the Scrum methodology was used, whose main advantage is to be aligned between the client or sponsor with the development team. The results of this research is that with the implementation of the business intelligence sy...

ABSTRACT The lack of information on the part of the agricultural producer generates some inconveniences in communication, loss of time and money, that is why it is looking for another communication alternative. This article deals with the benefits of implementing a Virtual Assistant in information management for integrated crop management. This is a Quasi-Experimental investigation where the survey was used as a technique for collecting data from agricultural producers in the province of Otuzco and the documentary review. To prepare the Virtual Assistant, the XP methodology was used, which comprises the following stages: Planning, Design, implementation and testing. The results of this research is that with the implementation of the virtual assistant it influences the costs of access to information, reducing costs by up to 90%. In addition, it determines that 77.46% of agricultural produ...

At the faculty of Engineering of the “Universidad Privada del Norte”, it was observed that the queries or doubts of the students about their academic processes, not only were answered in a slow way and generated queues, but also the information provided was not always the most reliable and this generated that the students have to make the query more than once. therefore, our objective was to determine the influence of an intelligent agent in the communication of academic processes of the engineering faculty of the “Universidad Privada del Norte”, San Isidro Trujillo headquarters in the year 2019. As a solution to the problem, the processes were analyzed and documented, which were the input values for training the intelligent agent. Two measurements were made, before using the agent and after using the agent in order to establish the best percentage in the effectiveness of the com...

Has completed extensive epidemiological, clinical , electrocardiographic and prophylactic regarding Chagas disease in the major population centers of two valleys of southern Peru , showing the presence of very favorable for the presence of this disease epidemiological factors . Almost 100% of households had T. infesfans and over 50% of them , these triatomines were infected with T. cruzi. Inside the homes of many and varied pets prevalent among guinea pigs, rabbits , cats and dogs , which have important role as a reservoir of T. cruzi are raised. 320 has been practiced xenodiagnoses to equal numbers of homes in Moquegua , resulting 12 positive among 113 dogs, 11 positive in 62 guinea pigs, 68 cats between 2 positive and 2 positive in 30 rabbits. The remaining (27 pigs , 8 horses , 6 goats, donkeys and 6 ) were negative. We practiced xenodiagnoses 752 and 553 reactions Guerreiro - Machado...
