Cómo apareció el nombre del pueblo "Cabeza de tigrillo" (Cómo ocurió la denominación de Quetzalapa)

The authors present two texts from the Guerrero Mixtec región. One relates how the town of Quetzalapa carne to be called in their language Xini Ñáña, "Head of a Tiger". It deals with the migration of a group of Mixtecs from a town calledCahuañaña, 'Tiger Rock', to Quetzalapa, and involves their custom of leaving the bones of the animals they eat as an offering after a meal. The other is the prayer that is said on beginning the construction of an adobe house. The authors note that adobe was introduced into the area only about forty years ago.

Seismic Reinforcement for Adobe Houses with Straps from Used Car Tires

After outlining introductory research on a proposed reinforcing system for adobe housing using straps cut from used car tires, the paper reports on full-scale tests. One dynamic and two static tests are described and results presented. The most significant outcome was that a single-room adobe house reinforced by tire straps successfully withstood the strong shaking that routinely collapses unreinforced adobe dwellings. The reinforced house strength, as measured during the shaking, exceeded the requirements of the Peruvian seismic code. This type of reinforced adobe can undergo large horizontal deformations without collapse. Design, construction, economic, and cultural issues are discussed prior to concluding that the proposed system can prevent collapse of adobe houses during damaging earthquakes.
