El objetivo de este trabajo fue determinar que de los métodos participativos en la mejora del aprendizaje de física básica en la institución educativa privada "Johannes Kepler", Trujillo 2017. Esta investigación se realizó, que es de un tipo aplicado a cuasi-experimental, siguiendo el diseño pre-experimental a solo un grupo. La población son los estudiantes de secundaria de la fundación de capacitación Johannes Kepler en la ciudad de Trujillo, 2017, y el muestreo se define de 20 estudiantes del quinto año, sección "A", del nivel secundario de la fundación de capacitación privada Johannes Kepler en la ciudad de Trujillo, 2017. Además de utilizar la encuesta para la recopilación de datos, se utlilizó una herramienta de prueba de conocimiento. Y al verificar la fiabilidad de los instrumentos, se ha utilizado el diagnóstico estadístico de Alfa De Cronbach (0.750); y esta v...

In internal dosimetry contribution and the significance of the dose of the radiopharmaceutical depends heart and biokinetics. Knowing the importance of the contribution offered the organ’s dose of the biokinetics as radiopharmaceuticals used for diagnostic, it has become a topic fairly specific within the internal dosimetry since the various organs of the human have specific physical and biological properties and this takes to have to be made a greater analysis before selecting the radiopharmaceutical for diagnostic, this mainly depends of the patient. This research consists to analyze and compare to what extent the radiation deposited in the organs source of the biokinetics of the heart contributes to the algorithm designed in Matlab. Our main objective is to design an interphase in Matlab using the Mird formalism and the representation of Cristy-Eckerman to consider the absorbed auto...

Purpose: To calculate the contribution of absorbed dose by organs in the biokinetics of Tc-99m when used for radiodiagnosis of the adult male heart employing a Matlab program. Methods: The absorbed self-dose of the adult male heart and absorbed dose by organs in the biokinetics of the heart when administering Tc-99m are estimated using the MIRD formalism and the Cristy-Eckerman representation, which have been employed to develop the algorithm in Matlab. Results: The results indicate that electron capture emissions of 1.446 (mGy/MBq) and Auger electrons of 0.062 (mGy/MBq) are entirely directed towards the target organ (heart) and contribute 29.33% and 1.25% respectively to its total dose. Additionally, the dosimetric contributions of biokinetic organs correspond to characteristic radiation emissions and gamma photons at 2.578 (mGy/MBq) for Tc-99m, representing 52.29% of its total dose.
