Furthermore, gray relational analysis was used to compare the comprehensive nutritional value. Results showed SPL HP1 had the highest protein value (30.8 \u00b1 0.4 g/100 g dw), while SPL HP3 had the highest content of vitamin C (104.6 \u00b1 4.9 mg/100 g dw), vitamin E (5.8 \u00b1 0.4 mg/100 g dw), total polyphenol content (9.1 \u00b1 0.3 g/100 g dw), antioxidant activity (DPPH: 7.4 \u00b1 0.1 g VcE/100 g dw; ABTS: 10.6 \u00b1 0.7 g VcE/100 g dw; FRAP: 0.617 \u00b1 0.005 \u00b5mol TroloxE/100 g dw), and comprehensive nutritional value (weighted gray relational grade 0.8336). The individual phenolic composition showed the presence of six caffeoylquinic acids, caffeic acid, and two flavonoids (quercetin and isoquercetin), which were significantly different among different harvest periods. In conclusion, HP3 was an optimal period for harvesting SPL.", "keywords": ["nutritional composition", "antioxidant activity", "Harvest period", "NUTRITIONAL COMPOSITION", "Food processing and manufacture", "HARVEST PERIOD", "Phenolic composition", "0404 agricultural biotechnology", "Antioxidant activity", "TX341-641", "https://purl.org/becyt/ford/2", "Sweet potato leaves", "2.

We explore the potential for generating electricity from biomass vulnerable to fires as an ecologic and socioeconomic opportunity that can reduce the risk of greenhouse gas generation from wildfires and help to create incentives to preserve natural and seminatural vegetation and prevent its conversion to agriculture, including biofuel crops. On the basis of a global analysis of the energy generation and spatial distribution of fires, we show that between 2003 and 2010, global fires consumed ~8300\uffc2\uffa0\uffc2\uffb1\uffc2\uffa0592\uffc2\uffa0PJ\uffc2\uffa0yr\uffe2\uff88\uff921 of energy, equivalent to ~36\uffe2\uff80\uff9344% of the global electricity consumption in 2008 and &gt;100% national consumption in 57 countries. Forests/woodlands, cultivated areas, shrublands, and grasslands contributed 53%, 19%, 16%, and 3.5% of the global energy released by fires. Although many agroecological, socioeconomic, and engineering challenges need to be overcome before diverting the energy lost in fires into more useable forms, done cautiously it could reconcile habitat preservation with economic yields in natural systems.</p>", "keywords": ["2.
