Study of alternative wastewater management in the northern sector, the town and Montecillo, Township Guatavita
No full textEn el presente trabajo se plantea la comparación de tres tipos de sistema, un filtro Imhoff, la PTAR existente y un Humedal artificial, para escoger una(s) opción(es) que coadyuve, en el tratamiento del agua residual vertida a la quebrada Montecillo del Municipio de Guatavita Cundinamarca. La comparación se hizo, estableciendo la población afectada, los caudales y cargas contaminantes esperadas, las áreas requeridas para implementación, un presupuesto estimado de construcción y mantenimiento, además el reconocimiento de las ventajas y desventajas de cada sistema, para finalmente proponer una solución y generar conclusiones.In this study comparing three types of system, an Imhoff filter Plant Wastewater Treatment exists and an artificial wetland is proposed, to select one (s) option (s) that contributes, in the treatment of wastewater discharged to the Montecillo broken Township Guatavita Cundinamarca. The comparison was made by establishing the affected population, flows and pollutant loads expected, areas required for implementation, estimated construction and maintenance budget further recognition of the advantages and disadvantages of each system, and finally propose a solution and generate conclusions.Pregrad
Complete genome sequence of rhizobium sp. strain 11515TR, isolated from tomato rhizosphere in the Philippines
No full text© 2018 Montecillo et al Rhizobium sp. strain 11515TR was isolated from the rhizosphere of tomato in Laguna, Philippines. The 7.07-Mb complete genome comprises three replicons, one chromosome, and two plasmids, with a GC content of 59.4% and 6,720 protein-coding genes. The genome encodes gene clusters supporting rhizosphere processes, plant symbiosis, and secondary bioactive metabolites
Near-complete genome sequence of ralstonia solanacearum T523, a phylotype i tomato phytopathogen isolated from the Philippines
No full textCopyright © 2018 Montecillo et al. Ralstonia solanacearum strain T523 is the major phytopathogen causing tomato bacterial wilt in the Philippines. Here, we report the complete chromosome and draft megaplasmid genomes with predicted gene inventories supporting rhizosphere processes, extensive plant virulence effectors, and the production of bioactive signaling metabolites, such as ralstonin, micacocidin, and homoserine lactone
The dependence of the characteristics of THz current oscillations on the quantum-well width in resonant tunneling diode
No full textEffects of harvesting on the structure of a neotropical woody bamboo (Otatea: Guaduinae) populations
No full textNatural populations of Otatea acuminata (Munro) C.E. Calderón & Soderstr. subsp. aztecorum (McClure & E.W. Smith) R. Guzmán, Anaya & Santana-Michel were studied in the Sierra de Manantlán, Jalisco-Colima, in Western Mexico. The objectives were to compare the structure of otate populations at different harvesting levels, in order to evaluate the changes occurred due to management and to obtain the best prediction factor for culm production. Forty-one 50m 2 plots were randomly established in harvested and non-harvested stands, and were observed over a 2 year period. There was no significant difference between harvested and unharvested stands, but the latter had higher densities and longer stems on average. Culm diameter and height were significantly different according to soil type in a nonparametric ANOVA. A backward lineal regression analysis identified a prediction model for juvenile culms production. Present exploitation levels by artesans appear to be sustainable
