Buildings standing on unstable soils are vulnerable to natural processes such as internal and external geodynamics and climate change. The village of Tapacocha, which is settled on slid floor, would be sensitive to those natural processes. The May 1970 earthquake caused ground fracture and building destruction; heavy rains in 1942 and 1997 caused mudslides that destroyed buildings and agriculture land. The internal geodynamics gave its shape to the base rocks through intense folding and fracturing of the sedimentary rocks; the external geodynamics created shapes through rotational movements, landslides and differential erosion. Presently, climate change is causing unusual torrential rains that periodically erode and threaten buildings and agriculture. The goal of this study is to advise the authorities and the population on ways to prevent and mitigate the destructive effects of these na...

Las construcciones civiles edificadas sobre suelos inestables son vulnerables a los procesos naturales como la geodinámica interna, externa y el cambio climático. El poblado de Tapacocha que está asentado sobre suelo deslizado es sensible a los procesos naturales. El terremoto de mayo de 1970 ocasionó fracturamiento de la planicie, destrucción de sus construcciones; las intensas lluvias de los años 1942 y 1997 ocasionaron huaycos que destruyeron algunas de sus edificaciones y terrenos de cultivo. La geodinámica interna modeló el basamento con un intenso plegamiento y fracturamiento de las rocas sedimentarias; la geodinámica externa por geoformas modeladas por los movimientos rotacionales, deslizamientos, erosión diferencial. En la actualidad el efecto del cambio climático se manifiestan por las inusuales torrenciales lluvias que erosionan periódicamente y ponen en peligro las...

The aim of this study was to develop a preliminary physical map of single nucleotide polymorphisms (SNPs) in alpaca using an alpaca/hamster radiation hybrid panel and a bovine high- density SNP genotyping microarray (BovineHD BeadChip-Illumina). The methodology included genotyping 92 alpaca/hamster hybrid cell clones, and four control samples (male alpaca, female alpaca, hamster and 1:10 DNAmixture) with the microarray. After genotyping the alpaca and hamster DNA control samples, only bovine SNPs with a call frequency of 1 were retained. The SNPs identified in the alpaca DNA samples were then filtered to remove those also found in the hamster. From the remaining alpaca SNPs, to decrease the probability of false positives, only those with a call frequency from 0.2 to 0.8 in the 92 hybrid clone samples were retained for the final analysis. The remaining alpaca specific SNPs were tabulated ...
