Authors: Li Ru , Huang Hui , Zhang Jia , Zhang Mengxin 
Published: July 2021

Abstract
In this paper, bibliometrics and visual analysis are used to analyze the fire safety related literature with the theme of “fire protection” and “safety” by CiteSpace software. The quality of fire safety management in China could be improved through the understanding of fire safety prominent risk and fire safety research hotspots. After searching, screening and exporting 2900 fire safety related literatures from China National Knowledge Infrastructure (CNKI), CiteSpace software was used to analyze the data exported from CNKI, and four kinds of visual maps including keywords, emergent words, authors and institutions were drawn. The atlas intuitively shows that the research hotspots from January 2015 to September 2020 are mainly focused on fire safety, countermeasures, high-rise buildings, fire hazards and so on. Many excellent authoritative authors have published articles, and different institutions have cooperated with each other, but the overall contact is less. Based on the overall situation, the investigation and treatment of fire hazards still need to be carried out in depth, and the fire safety management system needs to be further implemented.

Study on Energy Consumption Characteristics of Sewage Pipe under Different Conditions
Authors: Jiang Chao , Qing Leng 
Published: July 2021

Abstract
It can optimize the design of sewage pipe network system and select the design conditions of pipe network to obtain the best hydraulic characteristics and the most economical design plan by studying the hydraulic characteristics of sewage pipe network under different conditions. In this paper, k-s turbulence model is used to calculate the change of energy consumption characteristics in sewage pipe network under different working conditions. The results show that the pipe diameter is too small and the pressure on the pipe wall increases, which is not conducive to flood discharge. If the inlet velocity is too small, the negative slope of the pipe would lead to the reduction of the overall flow rate, which is easy to cause siltation of the sewage pipe network. Proper pipe diameter, inlet velocity and reasonable slope can help the pipe drain water. Increasing the diameter of the main pipe can improve the stability of the fluid, which is more conducive to sewage discharge.

Published: July 2021

Abstract
Defatted rice bran (DRB) and broken rice (BR) are by-products with large output in rice processing, but without being utilized properly. In order to strengthen the utilization of rice bran and broken rice, the pasting and rheological properties of the binary mixture of defatted rice bran-broken rice flour closely related to the adjustment of equipment and process parameters were studied. The results show that the peak viscosity, valley viscosity and final viscosity reduced during gelatinization, and the decrease increased first and then decreased with the rise of the proportion of defatted rice bran in the mixed system. Moreover, the addition of defatted rice bran may reduce the gelatinization temperature, attenuation value and setback value, reduce the difficulty of gelatinization and improve the stability of the mixed system. The conclusion revealed the binary mixture of defatted rice bran and broken rice flour belongs to pseudoplastic fluid, and the rheological properties are in accordance with the power law equation. The apparent viscosity of the binary mixture of defatted rice bran and broken rice flour is significantly affected by different mixing ratio, particle size and gelatinization temperature (P < 0.05).

Abstract
In order to determine the usage of the codon against Helianthus annuus chloroplast genome, this study used Codon W 1.4.2 and online software CUSP to perform neutral mapping, ENC-plot and PR2-plot analysis on the coding sequence codes of 51 genes in the H. annuus J-01 chloroplast genome. The results showed the GC content of H. annuus J-01 chloroplast genome codons was GC1 (47.14%) > GC2 (39.44%) > GC3 (28.42%), indicating that the preference for synonymous codons in the chloroplast genome ends with A/U. The average ENC value is greater than 45, of which 37 are greater than 45. It shows that the H. annuus J-01 chloroplast genome has a weak bias. Through neutral plot analysis, ENC-plot analysis and PR2-plot analysis, it is found that the preference of H. annuus J-01 chloroplast genome codons is affected by selection as the main factor. The 12 optimal codons in the H. annuus J-01 chloroplast genome were finally determined: CUU, AUA, UAU, UAG, CAU, AAA, CCA, ACU, GCU, GAU, AGU, GGA.

Published: July 2021

Abstract
The caramel color is one of the most widely used natural food colorants. At present, there are few reports about its modification. The modification of caramel is expected to improve its stability, color indexes and compatibility with food. In this paper, succinic and maleic acid modified caramels were prepared by esterification reaction of the raw caramel with succinic anhydride and maleic anhydride, and characterized by ultraviolet-visible (UV-vis) spectra, Fourier transform infrared (FTIR) analysis, and scanning electron microscope (SEM), etc. The significant changes of color, yellow and red indexes of the modified caramels indicated that the modification technique can be used to adjust the color properties of caramel to meet the various needs of different fields and expand the application of caramel. Compared with raw caramel, though the antioxidant ability of caramel was decreased, the thermal stability was improved, which made it more suitable for cooking and high temperature sterilization environment compared to the raw caramel. This study provided an alternative method for improving the performance of the caramel as food colors.

Published: July 2021

Abstract
The study was to determine the repellency of crude extracts of Epichloë bromicola at different altitudes against Tribolium castaneum Herbst, and the effect of crude extracts of endophytic fungi with higher repellent activity on superoxide dismutase, catalase and cytochrome P450. The percent repellency and the activities of three enzymes were measured at the concentration of 0.25mg/mL after 2h and 4h with different crude extracts. The correlation between altitude and avoidance rate was analyzed. The stain 1, 6, and 9 at the maximum concentration of 2.5mg/mL had better repellency (66%, 59%, and 65%, respectively). The concentrations of 0.25mg/mL treatment had a higher rate of avoidance, so this concentration was selected and the enzyme activity was determined. The activities of SOD, CAT, and CYP450 were significantly increased by three crude extracts of Epichloë bromicola compared with the control.
Effects of calcium on the formation of berry russet and phenolic compounds in ‘Shine Muscat’ grape
Authors: Huang Yan , Wang Pei , Wang Xiao , Wang Jin , Liu Fang 
Published: July 2021

Abstract
Four year old ‘Shine Muscat’ grape was used as the test material to spray amino acid calcium and water-soluble calcium solution on grape leaves and ears during fruit expansion and turn-color stages. A randomized block test was conducted to study the effects of exogenous calcium fertilizer on the formation of fruit russet and phenolic compounds in ‘Shine Muscat’ grape. The test was used to set the concentration of amino acid calcium solution to 1000 times, and to set the concentration of calcium water solution to 1500 times. With spraying water as a control. The results showed that: compared with water spraying, fruit russet was reduced in fruit expanding stage and turn-color stage, which could inhibit the accumulation of lignin, total phenol and total flavonoids, and affect the accumulation of eight phenolic acids in fruit peel. Spraying calcium fertilizer at fruit expanding stage was more conducive to inhibiting the accumulation of phenolic acids than that at turn stage, while spraying 1000 times of amino acid calcium at turn-color stage was more conducive to inhibiting the accumulation of gallic acid, caffeic acid, quercetin, coumaric acid and ferulic acid in pericarp than spraying 1500 times of water-soluble calcium and water. The results of this experiment can provide some guidance for grape production to supplement exogenous calcium and improve fruit quality.
