El presente estudio analiza el rendimiento en aserrío de dos de las principales especies comerciales de la zona de Chanchamayo, el tornillo (Cedrelinga catenaeformis Ducke) y moena (Aniba sp.), teniendo en cuenta las características promedio de las trozas y de un aserradero tipo de la zona. Para el tornillo se encontró un factor de conversión promedio de 0.58 y de 0.61 para moena; con base en estos resultados se elaboró una tabla de rendimiento de madera aserrada para cada especie. Los valores de las tablas elaboradas estadísticamente no difieren en forma significativa del rendimiento real.

Con el propósito de conocer la eficiencia de los métodos de motosierra, trozadora y hacha, en la ejecución del corte y trozado de árboles, se han  comparado dichos métodos en tres tipos de madera: dura, semidura y blanda; obteniendo los siguientes resultados: en madera blanda no existe diferencia de rendimientos entre los métodos, en cambio si, en madera dura y semidura en las cuales el rendimiento del método de motosierra es muy superior al hacha y trozadora y el de trozadora tiene ligera ventaja sobre el hacha. En cuanto a costos, los de métosierra son siempre menores que los de trozadora y hacha y esta diferencia se asentúa más cuando aumenta el costo de la mano de obra. Los costos de la trozadora son ligeramente menores que los de hacha.

We have studied the advantages, limitations and indications of the method of aspiration biopsy in a series of 80 breast tumors. From the results obtained it is concluded that this is a harmless method of great value in the anatomical diagnosis of ulcerated lesions in which biopsy should not be performed section; allows certain pre-operative diagnosis and nonsurgical in advanced cases, the only oprtunidad constitutye anatomical diagnosis. Close collaboration between the oncologist and pathologist, as a fundamental condition for good samples, and to provide proper interpretation of them is indispensable.

We have studied the histological structure of the cervix of 200 pregnant women with multiple biopsies taken during labor or immediately after him; then, in order to ascertain whether the histological changes found after señalaremos- which were permanent or only temporary and dependent on pregnancy, new biopsies 50 women, six and twelve weeks postpartum were taken, they are included in this group all wherein in the first biopsy showed these changes. In ten women (5%) histological alterations indistinguishable from carcinoma in situ was found; even in four of these cases they showed images suggestive of infiltration of the corium. In 18 women (9%) was found. nuclear atypia, which came to constitute some real monstrous cells. In 20 (10%) could be observed in cell disorder stratification and nuclear hyperchromatism. In 29 women (14.5%) increase in the number and size of nuclei in both the e...

Las empresas peruanas están en crisis con respecto a la gestión del talento humano (TH); ya que, pierden alrededor del 30% de sus empleados al año, esto resulta ser una cifra significativa, debido a que el punto crítico es perder el 10% de su TH [1]. Se evidencia que en la práctica la gestión humana (GH) es una problemática y muchas organizaciones fallan para gestionar sus talentos sobre todo en la adquisición de un personal competente y en su retención, debido a la falta de la elaboración de medidas de desempeño y la falta de integración de los elementos clave del sistema de gestión del TH. Por esta razón, se requiere un modelo de GH que integre los elementos claves para su desarrollo eficiente. Para este estudio se diseñó y aplicó un modelo de gestión del conocimiento (GC) en una empresa manufacturera con el fin de lograr resultados favorables con enfoque a la mejora ...

The present investigation research to study the Brand Personality in Careers belong to three Academic Areas of Universidad Nacional Mayor de San Marcos (Health, Humanities and Engineering), all them with accreditation requires. The aims were orientated to establish the features typical of brand personality of each one of the careers comparing the level of studies of the students (entry level: the first year, intermediate level: the third year, high level: the fifth year) and the genre. The population is constituted by the students’ totality registered in each of the careers and the sample by 553 students of Systems Engineering, Education and Psychology. The used instrument was the Aaker’s Brand Personality Scale, it consists of five dimensions: sincerity, competition, emotion, sophistication and hardness adapted by Denegri, M. (2009). The results establish typical different features ...

La presente investigación se planteó estudiar la personalidad de marca de carreras pertenecientes a tres áreas académicas (Salud, Humanidades e Ingeniería) de la Universidad Nacional Mayor de San Marcos (UNMSM), todas ellas con exigencias de acreditación. Los objetivos se orientaron a establecer los rasgos característicos de personalidad de marca de cada una de las carreras comparando el nivel de estudios de los alumnos (inicial: primer año, intermedio: tercer año, avanzado: quinto año) y el género. La población está constituida por la totalidad de alumnos matriculados en cada una de las carreras y la muestra por 553 alumnos de Ingeniería de Sistemas, Educación y Psicología. El instrumento utilizado fue la escala de personalidad de marca de Aaker, que consta de cinco dimensiones: sinceridad, competencia, emoción, sofisticación, dureza, adaptado por Denegri (2009).

Intimidation among coetaneans is a complex problem which is made up of not only the direct protagonists who are the students but also the teachers who interact permanently in the classroom and the educational centre. The goals are oriented to identify the predicting factors of the intimidation among coetaneans, perceived from the different roles (teacher, student), compare the perception of personal, family and socio-educative factors of the intimidation in students and teachers of different genre. The design of the research project is descriptive-comparative, the sample is 606 students and 70 teachers, all of them come from public high schools. The results establish meaningful differences in the perception of predicting factors of intimidation among coetaneans according to the role: teachers and students, from the perspective of genre, meaningful differences in the personal and family f...
