Authors: Hou Zhe , Lv Xinliang , Yang Bo , Liu Hao , Liu Shulin , Yu Changlong 
Published: July 2021

Abstract
The hot spot temperature of transformers operating in the station area is calculated in real-time using the transformer heat path model as it is impossible to measure the internal winding hot spot temperature directly and modifying the transformer will increase the cost. The smart distribution transformer terminal is an important device for collecting and processing data on the side of the distribution transformer, with a container built from Linux inside to run an application (App) with specific functions developed in the Linux environment. Based on that, the heat circuit model of the transformer is developed into an App installed into the container of the smart distribution transformer terminal to realize the function of the real-time computing and warning of transformer hot spot temperature. It is expected to provide some reference for the transformer operating normally and stably.

Abstract
Under the special environment of high temperature, high humidity and high salt, the development of the deterioration or latent defects of the arrester is accelerated. It is difficult to identify the abnormal state of arrester in special environment, only relying on the monitoring index of arrester. Therefore, this paper proposes a kind of lightning arrester defect recognition technology based on Naive Bayesian, which extracts the key features that affect the operation state of lightning arrester in special environment, and calculates the prior probability of training samples and the posterior probability of test samples through naive Bayesian algorithm, so as to identify the type of lightning arrester defects. The feasibility and correctness of the proposed method are analyzed and verified by the actual monitoring and detection data.

Authors: Hu Xiaochen , Wei Chenghui , Wang Shuang , Zhang Ze , Zhang Jing , Zhang Qichen , Shen Chenchen , Wei Jie 
Published: July 2021

Abstract
Dimethyl phthalate (DMP) is a common organic pollutant that can accumulate in aquatic organisms and pose a threat to aquatic ecosystems. Many studies have shown that DMP is toxic to marine organisms, but the toxicity mechanism of DMP in microalgae is still unclear. We measured indicators of cell growth, oxidative damage and antioxidant enzyme activity in Chlorella vulgaris exposed to DMP. The degree of growth inhibition of C. vulgaris cells increased with the increase of DMP concentration. Hydrogen peroxide and malondialdehyde contents increased significantly in C.vulgaris exposed to 800 mg/L DMP. Glutathione peroxidase and Superoxide dismutase activities both decreased in C. vulgaris exposed to 100 mg/L DMP. These data indicated that DMP treatment altered the redox status of C. vulgaris and that oxidative damage may be the main mechanism of DMP toxicity. The results lay a foundation for understanding the impact of DMP on C. vulgaris stress and provide a theoretical basis for the protection of aquatic ecosystems.

Published: July 2021

Abstract
Di-2-ethylhexyl phthalate (DEHP) is a toxic organic compound. It has been shown to exert negative effects on non-targeted aquatic organisms. In order to study the toxicological effects of DEHP on marine microalgae, we investigated cell growth, oxidative damage and antioxidant enzyme activities of Dunaliella salina under DEHP treatment. After exposure to DEHP of 10 to 800 mg/L for 7 days, D. salina growth was gradually inhibited with the increase in DEHP concentration. After D. salina was exposed to 400 mg/L DEHP for 4 days, the contents of malondialdehyde and hydrogen peroxide in D. salina were significantly increased as compared with those in the control group. After 6 days of exposure to DEHP at 10 to 400 mg/L, glutathione peroxidase activity in D. salina was significantly reduced in the 10 and 40 mg/L DEHP groups. Exposure of D. salina to 100 to 400 mg/L DEHP resulted in significantly higher inhibition of total superoxide dismutase in D. salina (p<0.05), and copper-zinc superoxide dismutase of D. salina was significantly inhibited compared with that of the control group (p<0.01). The results showed that DEHP exposure can damage the antioxidant defense system and cause cell death in D. salina.

Authors: Li Peiyuan 
Published: July 2021

Abstract
Hydrogen peroxide (H2O2) has great application prospects in the wastewater treatment environmental field due to its clean degradation product of merely H2O. While the green synthesis and highly efficient purification are also challengeable but significant. Thus, we intended to overview the H2O2 preparation methods, which are environmentally friendly, producing efficiently and economically. Here, we first discussed the most widely used H2O2 producing method of anthraquinone autoxidation synthesis method and put forward the main drawback. Six ideal substitute methods were next put forward which are oxidation of alcohols, photocatalysis, synthesis from CO/O2/H2O mixtures, direct synthesis method, fuel cell method, and direct electrosynthesis method. We then analyzed the traditional homogeneous Fenton process and summarized the promising substitute application of H2O2 in water treatment through heterogeneous Fenton processes from three main points. They are advanced heterogeneous iron oxychloride, heterogeneous electro Fenton catalytic assistance, and heterogeneous photo-Fenton catalytic assistance. Finally, a new sequential process of H2O2 applied in the environment as a form of water treatment was envisaged and named as One-stop Sequential H2O2 Process combining each way from the source and terminal. Additionally, in all the methods mentioned, we restated mechanisms and redrawn them more concisely and clearly to make them easier to understand.

Abstract
Objective: Intend to observe the effect of lycopene on reproductive toxicity induced by PFOS in male rats and its possible mechanism. Methods: 30 male SD rats were randomly divided into 5 groups with 6 rats in each group. The control group was given CMC-Na solution. At the same time, the PFOS group and the low, middle and high dose LP protection groups were fed with poisoned feed (32mg/kg PFOS-K).In the meanwhile, the lycopene protection groups were given LP every other day according to their designed dose, and were killed continuously for 3 months. In addition, the sperm motility, number, LDH-X, CAT, GSH-Px, SOD enzyme activity and MDA content were detected and observed. Results: The sperm motility was 44.00%, 53.68% and 58.37%, respectively.The rate of sperm deformity decreased, and the levels of LDH-X and serum testosterone (T) recovered in varying degrees. Moreover, low, middle and high doses of LP could significantly restore the activities of SOD and CAT and reduce the content of MDA, which was significantly different from that of PFOS group (P<0.05). Conclusion: 10∼20mg/kg LP can protect against reproductive damage induced by subchronic low dose PFOS. In addition, antioxidant damage and regulation of testosterone secretion are important mechanisms for LP to protect reproductive damage induced by PFOS.

Finding suitable materials to repair heavy metal lead pollution caused by mining, metal smelting and processing, domestic sewage discharge, sludge use, etc. is an important measure that needs to be taken at present. Mudstone is mainly composed of clay minerals such as illite, kaolinite, and montmorillonite. The clay minerals and secondary minerals contained therein have the basic characteristics of repairing soil contaminated by heavy metals. Therefore, mudstone can be used as a remediation method for soil contaminated by heavy metal lead. Potential material. In this study, indoor simulation experiments were conducted to study the effects of adding mudstone to the soil on the toxic dissolution of lead and soil enzyme activities. The results showed that the addition of mudstone significantly reduced the toxic dissolution of lead in the soil, and the degree of reduction was proportional to the amount of mudstone added and time. The strong adsorption of mudstone is an important factor in solidifying the heavy metal lead in the soil. In addition, mudstone has improved the physical and chemical properties of the soil to a certain extent, and played a role in improving the soil.

Authors: Raju R A , Akiyama M , Lim S , Kakegawa T , Hosono Y , Uno Y 
Published: July 2021

Abstract
This paper proposed a fabrication method of steel fiber reinforced concrete (SFRC) piles without shear reinforcement using the centrifugal forming technique to reorient the fibers perpendicular to the pile’s longitudinal axis for resisting the shear stresses. Effects of rotation patterns and concrete mixes on the fiber dispersion were investigated experimentally to identify the optimum procedure providing both well-oriented and well-distributed steel fibers. Using the X-ray radiography to visualize steel fibers inside the piles, it is confirmed that the centrifugal forming technique can realign the fibers in favor of the shear stresses. The shear test results show the effectiveness of the steel fibers in improving the shear strength of the SFRC piles due to good fiber dispersion. Moreover, the SFRC piles without shear reinforcement exhibited more ductile behavior than the RC piles with shear reinforcements. Steel fibers can be used to replace the shear reinforcements and improve the demanding productivity in the pile construction industry by saving time and labor.
