Estudio de viabilidad para la utilización de gas metano generado a partir de residuos orgánicos en la comunidad de Coper-Boyacá

Definir la viabilidad para la utilización de gas metano generado a partir de residuos orgánicos en la comunidad de Coper-Boyacá.Actualmente el sector ganadero y agrícola han tenido un gran desarrollo tecnológico, el cual ha permitido aprovechar los residuos generados por estos, como fuente de energía en zonas rurales de difícil acceso. El biodigestor es un tanque herméticamente sellado, que permite la fermentación anaeróbica de residuos orgánicos, generando en un tiempo determinado biogás rico en metano y bioabono, cuyo mercado objetivo es el municipio de Coper-Boyacá. Para el desarrollo del proyecto fue necesario un estudio de mercados a través de encuestas, para poder desarrollar el estudio técnico, la propuesta administrativa, organizacional y legal y el estudio financiero, con el fin de demostrar la viabilidad del proyecto.TITLE: FEASIBILITY STUDY FOR THE USE OF METHANE GAS GENERATED FROM ORGANIC WASTE IN THE COPER-BOYACÁ COMMUNITY* AUTHORS: Álvarez Niño Rita Paola, Buitrago Esparza José Rodrigo, López Palacio Carolina** KEY WORDS: Digester, Biogas, Biofertilizer, Feasibility, Organic waste. DESCRIPTION Currently the livestock and agricultural sector have had a great technological development, which has allowed to take advantage of the waste generated by these, as an energy source in rural areas of difficult access. The digester is a hermetically sealed tank, which allows the anaerobic fermentation of organic waste, generating in a certain time biogas rich in methane and biofertilizer, whose target market is the municipality of Coper-Boyacá. For the development of the project it was necessary to study markets through surveys, to develop the technical study, the administrative, organizational and legal proposal and the financial study, in order to demonstrate the viability of the project

Evolution over Time of Ventilatory Management and Outcome of Patients with Neurologic Disease∗

OBJECTIVES: To describe the changes in ventilator management over time in patients with neurologic disease at ICU admission and to estimate factors associated with 28-day hospital mortality. DESIGN: Secondary analysis of three prospective, observational, multicenter studies. SETTING: Cohort studies conducted in 2004, 2010, and 2016. PATIENTS: Adult patients who received mechanical ventilation for more than 12 hours. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Among the 20,929 patients enrolled, we included 4,152 (20%) mechanically ventilated patients due to different neurologic diseases. Hemorrhagic stroke and brain trauma were the most common pathologies associated with the need for mechanical ventilation. Although volume-cycled ventilation remained the preferred ventilation mode, there was a significant (p < 0.001) increment in the use of pressure support ventilation. The proportion of patients receiving a protective lung ventilation strategy was increased over time: 47% in 2004, 63% in 2010, and 65% in 2016 (p < 0.001), as well as the duration of protective ventilation strategies: 406 days per 1,000 mechanical ventilation days in 2004, 523 days per 1,000 mechanical ventilation days in 2010, and 585 days per 1,000 mechanical ventilation days in 2016 (p < 0.001). There were no differences in the length of stay in the ICU, mortality in the ICU, and mortality in hospital from 2004 to 2016. Independent risk factors for 28-day mortality were age greater than 75 years, Simplified Acute Physiology Score II greater than 50, the occurrence of organ dysfunction within first 48 hours after brain injury, and specific neurologic diseases such as hemorrhagic stroke, ischemic stroke, and brain trauma. CONCLUSIONS: More lung-protective ventilatory strategies have been implemented over years in neurologic patients with no effect on pulmonary complications or on survival. We found several prognostic factors on mortality such as advanced age, the severity of the disease, organ dysfunctions, and the etiology of neurologic disease
