Plasmodium vivax is the main cause of malaria in the Peruvian Amazon and Mazan is considered one of its districts with high risk of malaria transmission. In this site, previous studies has described P. vivax transmission as heterogenic and has suggested that its prevalence is influenced by factors linked to human mobilization. However, the contribution of this factor have not been assessed yet. Population genetic tools provide information on the individual contribution of the factors that favor the transmission and evaluate the demographic patterns of dispersion of the parasite populations which are influenced by the human mobilization. In order to evaluate contribution of human mobilization to malariatransmission in Mazan, in this work we use a Bayesian framework to identify genetic sub-populations in each basin and to discriminate between endogenous and imported cases. Socio-demographi...

Background: Plasmodium vivax remains a challenge in Peru. The high heterogeneity of its transmission has limited the intervention measures based on global and generalized epidemiological information at medium and long term. Population genetic tools may provide information on the spatial heterogeneity of transmission by linking parasite genetic patterns with epidemiological information. Methods: The genetic diversity and population structures from three settlements located in the Peruvian Amazon, Cahuide (CAH), Lupuna (LUP) and Santa Emilia (STE) were measured on samples collected from September 2012 to March 2015. Results: A total of 777 P. vivax mono- infections were genotyped. LUP showed the lowest proportion of polyclonal infections (0.197) and genetic diversity (Hexp 0.544 ± 0.0012). Moreover, in this study area results showed a significant increment of polyclonal infections and Hex...

En este trabajo de tesis se realiza el análisis y la implementación del control vectorial indirecto y control escalar para un motor de inducción trifásico de inducción con rotor tipo jaula de ardilla.

En el segundo capítulo se presentan los principios básicos del funcionamiento y la modelación matemática del motor trifásico de inducción, se desarrollan las transformaciones de Clark y de Park necesarias para lograr simplificar el análisis. Luego, se desarrolla el control vecto...

The African oil palm (Elaeis guineensis Jacq) is a crop that is widely distributed in tropical regions around the world; however, this crop is subject to limitations such as rapid trunk growth and susceptibility to bud rot and red ring diseases particularly in South America. To overcome these limitations, national breeding and conservation programs have been established, and there is a need to identify parental palms from natural populations of the American oil palm (E. oleifera H.B.K. Cortes) with desirable yield and morphological traits (i.e., yield production and bunch number) and with high genetic diversity. However, in Peru the morphological and genetic data related to this important crop is limited. In this study, we characterized the morphological and yield and estimated the genetic diversity using 12 neutral microsatellite markers (simple sequence repeats, SSRs) across 72 oil pal...
