![]() ![]() Remarkably, after immobilization, the PSP grafted on the wood substrate exhibited a faster photo response effect than the free spiropyran (SP). This novel membrane can efficiently separate stabilized water-in-oil and oil-in-water emulsions due to reversible hydrophilic-hydrophobic transition by switching UV and visible light irradiation. Herein, three-dimensional (3D) smart membranes with switchable superhydrophobic-hydrophilic surfaces were prepared by grafting photo-responsive poly-spiropyran (PSP) on wood-based substrates via surface atom transfer radical polymerization. However, the manufacture of multifunctional membranes with high efficiency, high flux and self-cleaning using renewable materials remains a challenge. Membrane separation technology has the advantages of low energy consumption and low cost, thus is an effective solution to the problems of oily wastewater. There is an urgent need to separate stable oil/water emulsions by efficient and environmentally friendly methods. Moreover, the study provides better references for popularization and application of these kinds of peanut harvesters.Oily sewage discharged from indiscriminate industrial and frequent oil spills have become a serious global problem. The results of comparative test and the analyses of the three types of peanut harvesters, provide the basis for theoretical research and optimized design of peanut harvesters, and also offer new methods for research and development of peanut combine harvesters. ![]() Experimental results prove that the performance of 4H-2 type peanut harvester is superior to those of the 4HW-700 and 4HW-800 peanut harvesters. Through comparative field experiment on the performances of the three types of peanut harvesters, the dominant factors including total loss rate, soil content and fuel consumption per hour, which control peanut harvesting targets, were analyzed. Three types of peanut harvesters, i.e., 4H-2, 4HW-700 and 4HW-800 peanut harvesters were selected as research. The mechanization level of peanut harvesting is lower than those of other crops, and it is concluded that the loss rate is higher, the reliability is worse and utilization efficiency is lower, through investigation and analyses of the mechanized harvesters for peanut at present in China. ![]() oxysporum, due to the increase in photosynthetic activity and thickness of the cuticle. This investigation reached as a conclusion that the application of fertilizers supplemented with silica, resulted in an improved growth of tomato plants and an increased resistance to F. The fertilizer with the best results on the severity and incidence was PSD, and best growth was observed when silica was applied at between 33 and 40%. The best result was observed when doses 20% higher than the recommended, were applied, and Cid F1 variety was more susceptible to F. ![]() The benefit of silica in plant growth was significantly associated with fertilizer sources and the applied doses. In PeƱuela, Veracruz, Mexico, from April to July 2015, doses recommended by the manufacturer, and also one 20% lower and other 20% higher of PSD, Silifertidol Ultra y Fosfosilidol fertilizers were applied to tomato plants. The objective of this work was to evaluate the effect of fertilization supplemented with silica on resistance of tomato to F. In fertilizers use, it is known that application of silica improves resistance to diseases. In this crop, Fusarium oxysporum causes one of the principal diseases that produce wilting and plant death. This fruit presents benefits as an antioxidant and is widely used in the Mesoamerican cuisine. Tomato production stands in first place worldwide. ![]()
