Estructura y mezcla genética de las poblaciones mestizas del noreste de México mediante el uso de marcadores moleculares autosómicos, mitocondriales y del cromosoma "Y" por Cerda Flores, Ricardo Martín

“…Se considera que los primeros pobladores del Continente Americano fueron ancestros asiáticos que cruzaron el estrecho de Bering, entrando en Alaska mucho antes del final de la glaciación Würm-Wisconsin, en una fecha que oscila entre los 15,000 y los 40,000 años, según los diferentes cálculos (Serrano-Sánchez, 1993). La fecha que marcó el inicio del proceso de mezcla, que desembocó en el estada actual de los grupos humanos, se ha fijado en el año 1492, ya que lo sucedido durante los dos primeros años, siguientes al viaje del navegante genovés Cristóbal Colón, modeló gran parte de la distribución humana del mundo actual (Coon, 1969).…”

A Dynamic Simulation Model for Growth of Penaeid shrimps por Mishra, A. K., Verdegem, M., van Dam, A.

“…The model was calibrated andvalidated with an independent data set.For calibration, the best agreement between observed and simulated value for growth wasachieved when it was assumed that 14% of dietary amino acids was converted to glucoseand ratio of fat: protein for energy generation was 0.819. Calculated regression equationand R2 were Y = 0.868X + 1.384 and 0.71, respectively, where Y is simulated and X is theobserved final shrimp weight. …”

A bi-objective model for the integrated frequency-timetabling problem por Avila Torres, Paulina Alejandra, Lopez Irarragorri, Fernando, Caballero Fernandez, Rafael

“…In this work we focus on the urban bus timetable construction problem which has two sub-activities: bus frequency calculation and bus departures setting. Typically, these sub-activities are done sequentially, which has some drawbacks: to overcome these drawback we propose to integrate both these sub-activities. …”
