Ingeniería e Investigación , 2011,
Abstract: energy forms the cornerstone of almost every economic, social and cultural sector in modern societies. energy is regarded as an irreplaceable ingredient in such societies' industrial development. the aim of this research was to estimate the generation of biogas in the city of ensenada's sanitary landfill to ascertain the amount of energy which could be generated from the solid waste being disposed of. biogas estimates were conducted in two stages: a waste characterisation study followed by implementing the regulations proposed by scs engineers (scs engineers, 2009) regarding the mexican biogas model (version 2.0). the results showed that a large quantity of organic matter (around 70%) is a key element in anaerobic degradation of waste. as to energy generation, it is believed that a full 1.90 mw capacity will be reached in 2019. such energy could increase ensenada's current electricity generation capacity by 3.46% and provide 60% of the energy needed for street lighting, thereby leading to usd $1.423 million in savings.

Abstract: Energy forms the cornerstone of almost every economic, social and cultural sector in modern societies. Energy is regarded as an irreplaceable ingredient in such societies’ industrial development. The aim of this research was to estimate the generation of biogas in the city of Ensenada’s sanitary landfill to ascertain the amount of energy which could be generated from the solid waste being disposed of. Biogas estimates were conducted in two stages: a waste characterisation study followed by implementing the regulations proposed by SCS Engineers (SCS Engineers, 2009) regarding the Mexican biogas model (version 2.0). The results showed that a large quantity of organic matter (around 70%) is a key element in anaerobic degradation of waste. As to energy generation, it is believed that a full 1.90 MW capacity will be reached in 2019. Such energy could increase Ensenada’s current electricity generation capacity by 3.46% and provide 60% of the energy needed for street lighting, thereby leading to USD $1.423 million in savings. El papel de la energía en la vida de las sociedades modernas ocupa un lugar central en casi todos los sectores económicos, sociales y culturales. La energía se considera como un ingrediente irreemplazable para las sociedades económicas y el progreso industrial. El objetivo de esta investigación fue estimar la generación de biogás del relleno sanitario de Ensenada (estado mexicano de Baja California) con la finalidad de conocer la cantidad de energía que se podría generar con los residuos sólidos depositados en él. La estimación de biogás se llevó a cabo en dos etapas: 1) se realizó un estudio de caracterización de residuos; 2) se siguieron los lineamientos propuestos por SCS Engineers (2009) del Modelo Mexicano de Biogás versión 2.0. Los resultados muestran una gran cantidad de materia orgánica (aproximadamente el 70%), lo cual es un aspecto clave en el proceso anaeróbico de los residuos. En cuanto a la generación de energía, se tiene que se llegará a una capacidad máxima de 1,90 MW en el 2019. Dicha energía podría aumentar la capacidad de generación eléctrica existente en Ensenada aproximadamente en un 3,46% y abastecer el 60% de la energía necesaria para alumbrado público, con un ahorro de 1.423 millones de dólares.

Abstract: Conocer las cantidades y tipos de residuos sólidos domésticos (RSD) que son depositados en el relleno sanitario, brinda la posibilidad de proponer opciones sustentables para su aprovechamiento. Los residuos de cualquier localidad manejados de forma apropiada se pueden convertir en insumos de algún otro proceso. El objetivo de este estudio fue cuantificar los componentes de los RSD susceptibles de ser reciclados, depositados en el relleno sanitario de la ciudad de Ensenada (Baja California, México), para ser valorizados en el mercado de los reciclables. En promedio se podrían comercializar semanalmente 643.67 toneladas de residuos alimenticios para composta, 389.45 toneladas de papel y cartón, 217.55 toneladas de plástico, 78.81 toneladas de vidrio, 37.20 toneladas de metales y 8.11 toneladas de aluminio. Se obtendría en total un aproximado de MXP $911,224.18 (USD $ 71,693.48) por la comercialización de los principales reciclables./ Knowing the amount and type of Domestic Solid Waste (DSW) that is deposited in the landfill gives us the possibility to consider options in how to make sustainable use of it.

Abstract: En las comunidades de Baja California, México, existen diferencias en las características propias de los sitios que impiden generalizar los parámetros para predecir la generación de biogás. Con el objetivo de proyectar con mayor precisión la generación de biogás, en esta investigación se determinó el índice de generación de metano (k) y el potencial de generación de metano (L0) en cuatro comunidades, dos urbanas (Mexicali y Ensenada) y dos rurales (San Quintín y Vicente Guerrero) de Baja California, México. Se realizaron estudios de caracterización de residuos, se utilizaron como base algunas constantes del Modelo Mexicano de Biogás Versión 2.0, y se siguieron los lineamientos del Panel Intergubernamental sobre Cambio Climático (IPCC). Los resultados muestran que el 64 % de los residuos generados son orgánicos, lo cual influye en el valor de los parámetros k y L0. Los valores de los parámetros promedio obtenidos en los cuatro sitios de estudio son similares a los rangos establecidos por el IPCC y el World Bank Group (WBG) (k = 0.0404 por a o y L0 = 73.645 m3/t de residuo). En algunos modelos los parámetros k y L0 ya están preestablecidos, sin embargo, se sabe que la determinación de estos parámetros in situ otorga una mayor certidumbre a la estimación de la generación de biogás.

Abstract: La hipertrofia mamaria severa supone para muchas mujeres el origen de una serie de trastornos físicos y psíquicos ampliamente reconocidos. Presentamos aquí los resultados obtenidos tras cirugía de reducción en pacientes con macromastia intervenidas en nuestro Servicio a lo largo de 8 a os, con la aplicación de dos técnicas diferentes: la técnica de Thorek y la técnica de McKissock. Fueron intervenidas un total de 98 pacientes, el 77,55% mediante técnica de Thorek y el 22,45% con la de McKissock. Las complicaciones postquirúrgicas fueron escasas en las dos técnicas, siendo el seroma y el hematoma las más frecuentes, además de la necrosis parcial/total del complejo areola-pezón en la de Thorek. El grado de satisfacción de las pacientes tras la cirugía fue "muy satisfactorio" o "satisfactorio" en la mayor parte de los casos. En casos de macromastia con ptosis severas la técnica de Thorek creemos que se perfila como la opción más adecuada. Cuando es viable, la técnica de McKissock permite una corrección excelente conservando la sensibilidad de la areola y el pezón.
