“…Figures 3 and 4 show the variation trend between icing failure rate and rainfall in line sections 70, 60, 09, and 83. It can be seen from Figure 4 that the overall trend of the change of fault rate in the four line sections increases with the increase of rainfall, but there are certain differences in different line sections due to the influence of geographical environment factors, wind speed, temperature, and other meteorological factors [23].…”

In order to study the dynamic assessment system of composite fault risk of transmission line based on blockchain energy and in order to study the transmission line compound fault risk dynamic assessment system based on blockchain, firstly, according to the coupling relationship between power grid and natural disasters, the information resources such as data collected by power grid intelligent devices and natural meteorology are excavated, and the overall architecture of power grid disaster early warning and decision-making system supported by blockchain is built. Then, from the perspective of risk, combined with analytic hierarchy process, an index system for reasonable evaluation of distribution network fault benchmark risk is established. Quantitative assessment and risk classification shall be carried out for the failure probability, failure impact consequence, and comprehensive failure risk, so as to facilitate the adoption of risk response measures. Finally, taking several 220 kV lines in the northwest and central part of a city as examples, the icing prediction analysis verifies the feasibility and effectiveness of the proposed power grid disaster early warning decision system based on blockchain to predict the icing thickness. The experimental results show that taking the icing disaster as an example, the MPC method is used to modify the icing thickness prediction model, improve the accuracy of the icing prediction model, and verify the feasibility and effectiveness of the prediction and early warning system based on blockchain.

IntroductionCotton straw biochar (biochar) and compound Bacillus biofertilizer (biofertilizer) have attracted wide attentions in the remediation of heavy metal-contaminated soils in recent years. However, few studies have explored the metabolomics of lateral roots of Cd-stressed cotton to determine the mechanism of biochar and biofertilizer alleviating Cd stress.MethodsIn this pot experiment, biochar and biofertilizer were applied to the soils with different Cd contamination levels (1, 2, and 4 mg kg-1). Then, the responses of cotton root morphology, vitality, Cd content, and antioxidant enzyme activities were analyzed, and the mechanism of biochar and biofertilizer alleviating Cd stress was determined by metabolomic analysis.ResultsThe results showed that exogenous Cd addition decreased the SOD and POD activities in cotton taproot and lateral root. Besides, with the increase of soil Cd content, the maximum Cd content in taproot (0.0250 mg kg-1) and lateral root (0.0288 mg kg-1) increased by 89.11% and 33.95%, respectively compared with those in the control (p< 0.05). After the application of biochar and biofertilizer, the SOD and POD activities in cotton taproot and lateral root increased. The Cd content of cotton taproot in biochar and biofertilizer treatments decreased by 16.36% and 19.73%, respectively, and that of lateral root decreased by 13.99% and 16.68%, respectively. The metabolomic analysis results showed that the application of biochar and biofertilizer could improve the resistance of cotton root to Cd stress through regulating the pathways of ABC transporters and phenylalanine metabolism.DiscussionTherefore, the application of biochar and biofertilizer could improve cotton resistance to Cd stress by increasing antioxidant enzyme activities, regulating root metabolites (phenols and amino acids), and reducing Cd content, thus promoting cotton root growth.

“…Also, it was found that the average dissolution rates of zinc, copper, cadmium, mercury, arsenic and lead in four kinds of CHMs were 47.4, 33.8, 20.5, 6.1, 5.4 and 4.8%, respectively, and the CHMs were considered to pose no threat to human health (Wang et al, 2019). Nan et al (2021) reported that the Platycodon grandiflorum accumulated varying amounts of metal(loid)s in the order copper > mercury > lead > arsenic > cadmium, and their concentrations decreased in the early growth stage and then increased in the flowering season. However, unlike human drinkable decoction, heavy metals may accumulate in tissues of pigs fed diets directly supplemented with herbal powder, especially when the dosage is large.…”

Chinese herbal medicines (CHMs) contain multiple active ingredients, such as polyphenols, flavonoids, polysaccharides, due to which CHMs have many biological properties for example antioxidant, anti-inflammatory and anti-lipase. CHMs can promote intramuscular fat deposition, increase the content of fatty acids and free amino acids in pork, which increases the nutritional value and health-promoting properties of meat. However, there are still some problems with the application of CHMs in pig production to improve meat quality. Firstly, there are many active ingredients, and their identification and study on their interactions are necessary. Secondly, the presence of harmful ingredients limits CHMs popularization and application. This review summarizes the current applications of CHMs in pig production in order to increase meat quality, and compares their effects on meat quality, which provides a theoretical screen for effective CHMs and their combinations. In brief, it is necessary to distinguish and find CHMs that have positive effects on meat quality and growth performance.
