Graphical Abstract
Abstract We produced and characterised biochar made from Caribbean pine sawdust as raw material. The (BC 500 ) was used biocompatible support to co-inoculate phosphate solubilizing bacteria (PSB) /PSB) on Allium cepa L., plants at a greenhouse scale for four months. three biomaterials study included proximate analysis, elemental aromaticity scanning electron microscopy, Fourier transform infrared spectroscopy (FTIR), adsorption studies different pH PSB stability function of time. results...
This paper proposes an integrated system architecture composed by a custom-designed lightweight Ground Penetrating Radar (GPR) and novel method for low-altitude autonomous flight called Backstepping+DAF. Simulations experimental results are carried out to evaluate how steady is achieved means of the proposed controller that consequently enables GPR detection buried objects with similar materials morphology real explosive landmines.
In peri-urban areas of Bogota, people harvest and use untreated rainwater. Initial research indicates that water collected from roofs contains high turbidity values, as well concentrations total suspended solids, biochemical oxygen demand 5-Day heavy metals. Moreover, these do not generally have access to public sewer systems. An eco-productive green roof with the aim reducing poverty improving quality life communities located Bogota has been described examined. These eco-roofs are made...
In this paper we present an approach for analyzing the inertial effects of changing wing shape steering a bat-like robot. Using BaTboT, robotic platform with massive morphing-wings, have estimated generation pitching and rolling torques, which are directly related to forward turning maneuvers. Results let us conclude that faster retraction wings during upstroke, slower extension downstroke increase both torques in about 50% compared those wingbeats equal periods retraction/extension. Also,...
Background and purpose: Urban trees provide a number of services including shade thermal attenuation.This is related to morphological physiological characteristics may vary between species even individuals the same species.The aim this work was identify thermic attenuations on concrete sidewalks under six tropical urban with different types shadows.Materials methods: In Santa Marta City, Colombia (10º12´20" N, 74º13´33" W, 10 meters above sea level 31ºC temperature), we selected (species)...
Introducción. Este trabajo de investigación se realizó en la Ciudad Honda, Colombia. Identificó el efecto sombra los árboles atenuación temperatura, humedad relativa, temperatura superficie del suelo, radiación solar y ultravioleta (UV) determinó requerimientos agua para vegetación arbórea. Metodología. Se tomaron datos aire relativa aire, radiaciones solares UV bajo a plena exposición. Resultados. encontró que osciló entre 50ºC exposición 41ºC sombra. La presentó valores 66.8ºC 42.6ºC...
<p>En este estudio se evaluó la atenuación hídrica de un techo verde utilizando tres<br />indicadores: lag-time, coeficiente escorrentía y volumen agua retenida. Se<br />registraron siete eventos lluvia su respuesta para dos tipos plantas<br />—Pennisetum clandestinum Melissa officinalis— tres profundidades sustrato (5,<br />10 15 cm), total seis tratamientos con repeticiones. Los experimentos<br />se realizaron en el del edificio “Rafael Arboleda”...
La cuenca de la Orinoquía colombiana, además caracterizarse por su diversidad ecológica, social, económica y cultural, se configura como una las zonas mayor dinámica petrolera en el país, actividad que ocupa cerca del 75% este territorio afecta manera importante recurso hídrico. De los requerimientos ambientales para protección agua Colombia, obligación invertir 1% valor un proyecto licenciado acciones preservación conservación hidrográfica cual abastece desarrollo sus actividades (de...
