Alternativas para mitigar excesivas vibraciones en puentes peatonales. by Rangel Banda, Jose Gerardo

“…Con el paso del tiempo factores como el desarrollo de procedimientos constructivos, el encarecimiento de los materiales de construcción, mano de obra y el ahorro de los costos finales de las obras ha generado una tendencia en el diseño en nuestro caso de estudio puentes peatonales, como el empleo de cubrir claros mayores con la utilización de estructuras más ligeras y flexibles, dando como consecuencia la disminución de rigidez y de masa, esto nos lleva a frecuencias naturales menores que resultan en una mayor sensibilidad a cargas dinámicas que a menudo coinciden con la frecuencia del andar de las personas, ocasionando vibraciones que producen desplazamientos, esto pone en riesgo la estabilidad de la estructura y por consecuencia la comodidad del usuario. …”

Metallophilic fungi research: an alternative for its use in the bioremediation of hexavalent chromium by García Hernández, María de los Ángeles, Villarreal Chiu, Juan Francisco, Garza González, María Teresa

“…Short-term exposure to hexavalent chromium can cause irritation, ulceration in skin and stomach and in addition to cancer, dermatitis, and damage to liver, renal circulation and nervous tissues, with even death being observed in response to long-term exposures. Many techniques have been used for the remediation of this pollutant, including physical and chemical approaches and, in more recent years, biological methods. …”
