In this work, a modification of the sugarcane bagasse is performed, in order to obtain organic catalysts. The bagasse analysis is performed using X-ray diffraction (XRD) and Fourier Transformer Infrared Spectroscopy (FTIR), which indicated that characteristic peaks determined its chemical compounds. In addition, Scanning Electron Microscopy (SEM) is used to know the morphology. Finally, a discoloration test is conducted on an azo compound (methylene blue) in an aqueous medium, obtaining an efficiency of 98.6%.

The paper presents an efficient form of growing arugula plants by means of automatic control of an aeroponic culture irrigation *** system considers a reprogrammable electronic circuit that uses software to generate different irrigation cycles to obtain an adequate growth of arugula *** show how different samples grown in a greenhouse had the same growth behavior as field-grown samples during the test *** was possible to obtain a more efficient and sustained five-week production to supply consumers by having a continuous cycle irrigation system,which was operated for 35 *** growth and number of leaves were maintained in a similar way for different plants *** grow similarly,but some of them showed size differences during the five weeks.

介绍了一种利用可灌溉雾化栽培系统自动控制种植芝麻作物的有效方式。该系统采用一个可重新编程的电子电路,使用软件生成不同的灌溉周期,以获得芝麻作物的充分生长。结果表明,在试验期间,温室中生长的样品与田间生长的样品具有相同的生长行为。通过连续循环灌溉35天,可以获得更高效、更持久的五周产量,以供应消费者。所分析的不同植物的叶片生长和数量均保持一致。根系生长状况相似,只是其中一些在五周内表现出大小差异。
