Resistance Reduction Scheme for Tower Grounding with Conductive Cement
Lun Li,Tian Xu,Pei Feng,Liu Xin,Jia Lulu,Deng Chenxing,Wang Xing,Lan Fen,Cheng Hongbo 대한전기학회 2021 Journal of Electrical Engineering & Technology Vol.16 No.3
The construction conditions of transmission lines are becoming more and more diffi cult. It is necessary to fi nd new ways to reduce the grounding resistance of poles and towers at high soil resistivity and small construction area. Conductive cement samples with graphite, stainless steel fi bers, and their mixtures as conductive phases materials were prepared, the resistivity, fl exural strength and compressive strength were tested, compared and analyzed. The graphite and stainless steel fi ber conductive cement with better comprehensive performance was selected out for tower grounding. The application schemes of conductive cement for tower grounding were designed and compared, the partial wrapping scheme was selected and its application methods under diff erent soil resistivity was analyzed. The analysis results can provide theoretical basis and guidance for the application of conductive cement in transmission tower grounding, the feasibility of scheme is proved by the fi eld application.

Chemical investigation of the fermentation broth of a Soft Coral-Derived fungus Pestalotiopsis sp., led to the isolation of a new phthalide derivative, pestalotiolide A (1), three known analogues (2, 3 and 4), along with 5'-O-acetyl uridine (5) first isolated as a natural product. The structure of the new compound (1) was established by comprehensive spectroscopic analysis and chemical methods. Compounds 1 - 4 possessed varying degrees of antiviral activities, which was reported for the first time. Compared to the positive control ribavirin (IC50 = 418.0 μM), pestalotiolide A (1) exhibited significant anti-EV71 activity in vitro, with an IC50 value of 27.7 mM. Furthermore, the preliminary structure-activity relationship of antiviral activities was also discussed.

The comparison of microbial communities in thyroid tissues from thyroid carcinoma patients
Liu Chen-Jian,Chen Si-Qian,Zhang Si-Yao,Wang Jia-Lun,Tang Xiao-Dan,Yang Kun-Xian,Li Xiao-Ran 한국미생물학회 2021 The journal of microbiology Vol.59 No.11
Thyroid carcinoma is a common endocrine organ cancer associated with abnormal hormone secretion, leading to the disorder of metabolism. The intestinal microbiota is vital to maintain digestive and immunologic homeostasis. The relevant information of the microbial community in the gut and thyroid, including composition, structure, and relationship, is unclear in thyroid carcinoma patients. A total of 93 samples from 25 patients were included in this study. The results showed that microbial communities existed in thyroid tissue; gut and thyroid had high abundance of facultative anaerobes from the Proteobacteria phyla. The microbial metabolism from the thyroid and gut may be affected by the thyroid carcinoma cells. The cooccurrence network showed that the margins of different thyroid tissues were unique areas with more competition; the stabilization of microcommunities from tissue and stool may be maintained by several clusters of species that may execute different vital metabolism processes dominantly that are attributed to the microenvironment of cancer.
