El objetivo de este trabajo de investigación fue los profesores y profesoras de Educación Básica Regular y superior deben fomentar la investigación en todos los niveles, con el objeto de formar estudiantes comprometidos en resolver los problemas que la sociedad demanda. La formación científica es importante, porque desde las instituciones educativas se debe brindar experiencias o situaciones significativas que despierten el interés y las expectativas para hacer ciencia, esto involucra un acercamiento a la realidad en la que el estudiante se desenvuelve con la finalidad de que pueda identificar las necesidades, problemas y demandas. El tema de la célula es importante como conocimiento base, puesto que es la unidad básica de un ser vivo que ejerce muchas funciones, siendo una de ellas la mitosis. En el presente trabajo de investigación hemos tratado sobre la mitosis en los animal...

The presented work demonstrates the process of designing a cheap, low cost three axis force sensor. Further it describes its integration in an array of multiple sensors to measure the distribution of forces acting on the sole of a prosthetic foot. The focus will be on easy manufacturing and common materials since the sensor will be integrated in a low cost prosthesis for lower limp amputees. Using the knowledge from bio mechanics and some basic assumptions for the later use, requirements for the project are derived. After a presentation of some state of the art sensor principles, suitable concepts are collected. Than, the concepts are compared using a comparison table to find the one the fits the requirements the best. A very compelling concept using barometers casted in silicone rubber is tested using a simple prototype to try out whether it is a good candidate or not. The tests show th...
