Esta investigación tuvo como propósito principal determinar el diseño del pavimento flexible para mejoramiento del tránsito vehicular del camino vecinal Vichayito, del distrito de Máncora, 2021. Se planteó un estudio de enfoque cuantitativo, de tipo aplicado y diseño no experimental, trabajando con una muestra consistente en la vía de acceso a Vichayito - distrito de Máncora, misma que fue extraída de una población de estudio consistente en todos los caminos vecinales del distrito de Máncora. Se empleó la técnica de la observación y como instrumentos se emplearon estudios de suelos y fichas de conteo vehicular estandarizada por el Ministerio de Transportes y Comunicaciones. Los resultados mostraron un suelo con CBR de 20%; un índice medio diario de 185 vehículos por día, valores que se emplearon para realizar el diseño del paquete estructural del pavimento mediante el ...

This paper analyzes the genetic diversity of 79 accessions of native potato varieties (Solanum spp.) using 18 microsatellite markers. A random sample from Ayacucho, Cajamarca, Cusco, Huancavelica and Puno from "chacras" of farmers who collaborated with the "In situ conservation of native crops and wild relatives" were used. 17 markers amplified one single polymorphic locus, the mean number of alleles per locus was 8.79. The mean similarity was 0.62 and clustering indexes varied between 0.41 and 0.98. 19 loci showed a total of 166 alleles. Cuzco had the highest number of alleles (130 alleles). Of the 166 characterized alleles, 72 alleles (43.37%) were common or shared with 5 sampling sites. Puno had the highest number of exclusive alleles (8 alleles). The 42 varieties of S. tuberosum subsp. andigena showed a mean diversity of 0.74 and 18 varieties of S. x chauchaan average diversity of 0....
