Compatibilidad de dos metodologías para la mejora de intersecciones no semaforizadas peligrosas en el distrito de El Tambo, Huancayo-Junín 2018

Camayo Armaulia, Cristian Maicol 17 May 2019 (has links)
El presente trabajo de tesis titulado “Compatibilidad de Dos Metodologías para La Mejora de Intersecciones No Semaforizadas Peligrosas en el Distrito de EL Tambo, Huancayo – Junín 2018”, consiste en el análisis de dos metodologías el “Manual de Capacidad de Carretera” (HCM 2000) y el “Manual de Dispositivos de Control de Tránsito Automotor para Calles y Carreteras” del (MTC), en intersecciones no semaforizadas.Finalmente, se llevó a cabo una discusión de los resultados que se muestran en el capítulo 4.3 mediante tres análisis de compatibilidad entre las dos metodologías, para determinar la compatibilidad entre sus resultados; bajo estos tres análisis, se determinó que ambas metodologías proveen una mediana compatibilidad de resultados, mas no en su totalidad, ya que coinciden en las intersecciones I_02, I_03, I_05 e I_06 y discrepan en las intersecciones I_01 e I_04, además de ser metodologías complementarias entre sí.

Pasture renovation with herbicide suppression of weeds and no-till seeding of orchardgrass

Fitzsimmons, James P. 17 June 1993 (has links)
No-till pasture renovation can increase the quality and forage yield of underproductive pastures. Decreased erosion, lower costs, and less lost grazing time are advantages of no-till renovation compared to conventional renovation. Unwanted vegetation is first controlled with herbicides to decrease competition for introduced orchardgrass. Two field trials were conducted using a split-plot design to compare three seeding methods and two herbicides. An Aerway no-till drill, a Tye double disk drill, and broadcast followed by harrowing were the seeding methods. Paraquat and glyphosate were used to determine herbicide effect on vegetation control. Orchardgrass did not adequately survive at either trial site. However, where some orchardgrass did survive, vegetation control was more important than seeding method. Competition from annual grasses, many germinating after herbicides were applied, was the reason for renovation failure. Herbicide and initial growth for best control. Yield was doubled in the first harvest by the addition of fertilizer. Early spring forage production from poor pastures is usually more than adequate, so the increase from fertilizer is of marginal value unless it is stored for later use. Yield increase did not carry over to the second harvest when it could be better utilized. Later application dates would extend yield increases from certain species if water is available. / Graduation date: 1994
