  • Artemisia herba alba Essential Oil: GC/MS analysis, antioxidant activities
           with molecular docking on S protein of SARS-CoV-2

    • Authors: Khaoula Diass; Imane Oualdi, Mohammed Dalli, Salah-eddine Azizi, Mounir Mohamed, Nadia Gseyra, Rachid Touzani, Belkheir Hammouti
      Abstract: This study was conceived to work on Artemisia herba alba essential oils (EOs) originating from Eastern Morocco. We investigated the chemical properties and determined the antiradical scavenging activity. The GC-MS technique was used to elucidate the chemical composition of the two studied regions. Jerada Eo was distinguished by the existence of 1,6-Dimethylhepta-1,3,5-triene (36.44%), Camphor (22.50%), and Thujone (7.21%). While, Taourirt EO was found to be rich in Camphor (55.31%), Eucalyptol (14.64%), and Camphene (9.95%). Moreover, the free radical scavenging ability (DPPH•), and ferric reducing power assay (FRAP) were conducted. The EOs tested are found to be weakly active and to have important antioxidant potential. The docking study was also carried out by theoretical investigation with molecular docking of four active predominating components (1,6-dimethylhepta-1,3,5-triene; Chrysanthone; Eucalyptol; Alpha-pinene) against S protein of SARS-CoV‑2, and all the four ligands were found to bind to the S protein 6CS2 of SARS-CoV-2 differently and that the stable complex formed as a result of these interactions may prevent the binding of ACE2 with the spike S protein of SARS-CoV-2.

  • Products of Apatite-Nepheline Ore Processing in the Synthesis of
           Low-Modulus Zeolites

    • Authors: Yana A. Svakhina; Marina E. Titova, Igor N. Pyagay
      Abstract: The article presented the results of studies on the production of low-modulus zeolites from two types of technogenic resources containing a sufficient amount of silicon in their composition. The raw materials were nepheline concentrate and silica gel, which are products of the processing of apatite-nepheline ore. Directly before the synthesis of low-modulus zeolites, the morphology, chemical composition, and particle size of the starting materials were analyzed. The optimal parameters for sample preparation and purification of the raw materials used were also selected. The influence of the ratio of components in the reaction mixture on the type of synthesized zeolite and its characteristics were studied. The properties of synthesized zeolites from the proposed type of raw material were compared with the properties of zeolites synthesized today using the popular technology from kaolin clay, which is currently offered as an inexpensive natural raw material.
       
  • Analysis of the behavior of asynchronous electric drive with a closed
           scalar control system when changing the inductance of the magnetizing
           circuit

    • Authors: Yu. L. Zhukovskiy; B. Y. Vasilev, N. A. Korolev, Y. M. Malkova
      Abstract: The article was devoted to the study of an automated electric drive with a scalar closed-loop speed control system. Severe duty and operating modes of electric drive determine the actual service life. Wear of the induction motor, as a key link of the electric drive, was associated with deviation from nominal parameters. The deviation of parameters of the induction motor equivalent circuit determined the resultant change of characteristics. The parameters of the equivalent circuit determined the accuracy of the adjustment of regulators and optimal algorithms in the control system of the electric drive. In continuous operation modes the possibility of auto-tuning regulators, which requires stopping or no-load mode, was excluded. The paper considered the influence of the magnetization circuit mutual inductance value of the induction motor on the behavior of the electric drive control system. Evaluation of the behavior of the scalar closed-loop speed control system was performed on the basic energy (power factor, efficiency factor) and mechanical (speed, electromagnetic torque) characteristics of the electric drive.
       
  • Literature Review and Experiment: Diversity of Bacteria in Forest,
           Revegetated Post-Mining Land, and Active Tin Mining with A Metagenomic
           Approach

    • Authors: Eka Sari; Andhika Puspito Nugroho, Endah Retnaningrum, Irfan Dwidya Prijambada
      Abstract: The objective of this study was to investigate the diversity of bacteria in the rhizosphere of Acacia grow in the forest and different ages of revegetated land and non-rhizospheric bacteria from active tin mining soil on Bangka Island with a metagenomic approach and to investigate its relationship with physicochemical properties of the soil and its metal content. 17 species/genera were found in the four fields, and Bradyrhizobium is the dominant genus. Bacterial communities of the forest (more than 5 years in revegetated post-tin mining land containing C, N, P, and Fe) are Paraburkholderia sp., Bacillus sp., Candidatus-Xiphinematobacter, and Bacterium enrichment. The physicochemical properties of soil from less than 5 years of revegetated contain Cu, Cr, and Mo, and the dominant species in this soil were Bulkhorderia sp., Bacillus lehensis, B. fordii, B. thermolactis, Chloroflexi bacterium, and Thermonosporaceae bacterium. The physicochemical properties of soil from the mining were dominated by Cd and Ni, and the dominant species in this soil were Sinomonas atrocyanea.
