The growth of Tetraselmis suecica was evaluated. The experiment was realized using the Response Surface Methodology (RSM) with Central Composite Rotational Design (CCRD) with two factors, pH and sanguaza/seawater concentration in the range of 7 - 9 and 2 - 5 % (v/v), respectively. The culture media were stirred by bubbling air constantly (0.07 L/s) and continuously illuminated with 40 W of fluorescent light in glass containers of 1.5 L capacity at a temperature of 22.5 ± 2.1 °C. Using the Gompertz mathematical model was determined that from an 8.0 of pH and a ratio of 3.5% of sanguaza/seawater, the Tetraselmis suecica achieves maximum growth. An 8.71 of pH and a ratio of 4.56% of sanguaza/seawater allow the Tetraselmis suecica maximum growth (logN/N0) of 0.659, with a 12.3% of prediction error by applying a mathematical model of 2nd order. According to the study, the values obtained in...

RESUMENLos fracasos de los implantes producidos después de la carga funcional están principalmente relacionados a factoresbiomecánicos. Diversos análisis han demostrado que el macro diseño del implante y el tipo de conexión pueden afectar latransmisión de fuerza al hueso peri-implantar.OBJETIVO: Evaluar la distribución de tensiones en el hueso y el implante ante una fuerzas horizontales y verticales entres diseños de implante de conexión interna: Octodecágono, hexágono interno y cono morse; por medio de análisis enelementos finitos (MEF).MATERIALES Y MÉTODOS: Los tres diseños de conexión interna tuvieron aplicación de fuerza horizontal y vertical del150N. El modelado geométrico de los sistemas de implantes se realizó con el software Solid Works 2011. Se obtuvieronresultados mediante el análisis de Von Mises a través del programa Cosmo Works.RESULTADOS: El menor valor...
