It all depends on how much xenobiotics damage the immune and hormonal systems. Therefore, viruses are not the cause, but the consequence of the disease. The fight against viruses with the help of vaccines prepared on their basis has been violating and restraining the natural mechanisms of regulation of biological processes in plants and mammals. Thus, molecular motifs arising from microbiota bacteria become either apaptogens (viruses) or adaptogens. In the first and second cases, genetic information is released into the environment. In the latter case, there is an adaptation or a kind of vaccination of others by a natural mechanism. This mechanism is also applicable to somatic diseases, such as cardiovascular, autoimmune, oncological, etc. As for the original properties of coronaviruses, it is their ability to suppress innate and acquired nonspecific viral immunity in the respiratory tract. This leads to the reactivation of chronic, mainly bacterial, respiratory infections - pneumococci, staphylococci, hemophiluses, however, fungal infections can also be observed – mucormycosis, aspergillosis, etc. This feature of the virus prompted doctors at the beginning of the epidemic (2020) to use a pneumococcal vaccine, which, as it turned out, similarly to the coronavirus vaccine reduces the severity of the disease and mortality. As for the diagnosis of coronavirus infection and its treatment, as practice has shown, everything depends on the stage of the disease, starting with a viral and ending with a bacterial infection. Similar and identical antigenic determinants in coronavirus and respiratory group bacteria often caused confusion when analyzing the results of serological and molecular biological diagnostic tests in patients with COVID-19. Moreover, the justified use of antibiotics in the post-viral, that is, in bacterial periods, made it possible to successfully treat patients with a positive PCR test for coronavirus on an outpatient basis.","PeriodicalId":177098,"journal":{"name":"Journal of Environmental Science and Engineering Technology","volume":"4 2‐3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139000329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

That is why the efficiency concept has to be present at all levels of industrial and financial activities. The proposed concepts in this paper could be further developed as a model for improving companies’ corporate energy policies. \u0000Nowadays, some purchase decisions for equipment are still driven predominately by the purchase price, and the full consequences of energy efficiency and the impact on the environment are not always considered. \u0000In general relatively “low value equipment” purchase policy is still driven by purchase price only, in spite of the evidence that such price represents a maximum of 5 % to 7 % of the total expenses related to the total costs of ownership. In the minerals industry “low value equipment”, like low-voltage motors (up to 1100 volts, 50/60 Hz), are found many times and in very large numbers, their efficiency and reliability influencing dramatically specific costs of technological processes. \u0000Although with “major equipment” energy savings are considered more in the purchase decision, every growing importance on the environment of “Green House Gas” (GHG) emissions is still not a major factor when selecting equipment. Often more traditional equipment is purchased at the expense of new innovative technologies that in addition to providing energy savings can also be used as a tool for trading Carbon Credits in the financial marketplace. An example of such a technology is the IsaMill™ comminution machine, which is becoming more widely used in gold and general mining operations in South Africa and throughout the world. Comminution in the mining industry is one of the most energy intensive activities in the world, and the innovative use of “major equipment” saving power can also have a positive effect on the environment. \u0000The paper presents descriptions of the essentials of the Global Efficiency (GEff) concept that has been promoted over the last years in South Africa. Price-efficiency criteria (as a corollary of GEff) are investigated for applications incorporating equipments that are driven by low and high voltage motors. \u0000The paper presents theoretical and technical aspects analysing the economic and environmental impact, by reducing total cost of ownership with energy savings, for one “low value equipment” in typical applications largely used in mineral processing in the gold mining industry, and one “major equipment” purchase at a current operating gold mine where the innovative IsaMill™ comminution technology was installed as an alternative to traditional older technologies. \u0000Besides the impact of energy savings with high-efficiency technological processes and new innovative developments, this paper suggests the general impacts of: \u0000 \u0000Technical and economical performance improvements and competitiveness of mining corporations to international standards; \u0000Defusing incipient ene","PeriodicalId":177098,"journal":{"name":"Journal of Environmental Science and Engineering Technology","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139009682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These nanocomposites have the potential to exhibit enhanced biological applications, such as antifungal, enzyme immobilization and antibacterial activities, compared to bare graphene oxide (GO) and phosphoramides. This research delves into the detailed investigation of three GO-based membranes, where GO serves as substrate for phosphoramide ligands. It has been demonstrated that these membranes possess wider interlayer D-spacing compared to GO. The compounds were characterized using various analytical techniques, including IR and NMR spectroscopy, AFM, XRD analysis, and UV-visible spectroscopy. Furthermore, this study delved into the mechanisms underlying the immobilization of Acetylcholinesterase enzyme (AChE) by GO and its newly synthesized derivatives. The results obtained from this study demonstrated that the GO/L films possessed enhanced biological activity compared to both phosphoramide ligands and bare GO alone. The objective of this research was to develop simple and efficient methods for synthesizing potent compounds that can find applications in various biological fields. Notably, these compounds offer advantages in terms of their environmental friendliness, cost-effectiveness, and time efficiency. The findings of this investigation contribute to a deeper understanding of GO-based membranes and open possibilities for rational design in diverse areas such as drug development and food industry.","PeriodicalId":177098,"journal":{"name":"Journal of Environmental Science and Engineering Technology","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124918593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stable isotope signatures of macrophytes indicate the environmental conditions and macrophyte contributions to food webs. However, macrophyte isotope signatures have been studied less than isotope signatures of other organisms. We determined the stable C and N isotope signatures of 10 aquatic plant species from Poyang Lake wetland (Wucheng, Yongxiu County) and Nanji wetland (Nanjishan, Xinjian County) in Jiangxi Province, which are Chinese national nature reserves, among different seasons. The isotope signatures for different species and seasons were significantly different. The dominant macrophyte species were Potamogeton malaianus and Nymphoides peltatum. The isotope signatures for different organs of these two species were determined. Both δ13C and δ15N values were higher for P. malaianus than for N. peltatum stems, roots and leaves, and δ13C varied less for N. peltatum than for P. malaianus organs. The δ13C and δ15N values for P. malaianus organs increased in the order roots<stems<leaves. δ13C values for N. peltatum organs decreased in the order roots>stems>leaves, and δ15N values for N. peltatum organs increased in the order roots<stems<leaves. The stable C and N isotope signatures for P. malaianus and N. peltatum may be controlled by various factors including macrophyte life history, external sources of C/N, and the amount of water in the wetland. These results provided a theoretical reference and experimental data support for detecting the flow trend of C & N elements and environment changes in the lake by the δ13C and δ15N values of euhydrophytes.","PeriodicalId":177098,"journal":{"name":"Journal of Environmental Science and Engineering Technology","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115411783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, studies on cyanobacteria inoculation in abandoned ionic rare earth mines were still insufficient. The abundance and composition of microorganisms in the topsoil of abandoned ionic rare earth mines were analyzed using high-throughput sequencing of the 16S rRNA V4 gene in this study. Fifteen samples were selected in and around rare earth mine tailings based on five different habitat types to assess the difference of main bacteria component and the dominant cyanobacteria caused by environmental factors. A total of 713,057 effective 16S rRNA genes were classified into 30 bacteria phyla, and 7 cyanobacterial genera were determined in phyla of Cyanobacteria. Proteobacteria, Chloroflexi, Acidobacteria, Actinobacteria, Planctomycetes, and Cyanobacteria were dominant groups in all samples (>5% of total effective sequences).

As one of ecological footprint methodology, carbon footprint is emerging as an effective tool for carbon emission management, especially that from fossil energy consumption. Taking one of the most developed regions in China, the Yangtze River Delta as a case study, this paper analyzes carbon footprint of fossil energy consumption through productive lands by explicitly addressing spatial changes of land use/cover. The impacts of land use change on the carbon footprint are then assessed by coupling changes in land use/cover and fossil energy consumption. The results show that carbon footprint from energy consumption in the Yangtze River Delta increased from 322531 km2 in 2001 to 862924 km2 in 2013. Despite the fact that productive lands (i.e., forest and grasslands) were rising, the carbon footprint was still in deficit, about 831873 km2 in 2013. According to scenario analysis, carbon footprint is expected to reach 2572837 km2 in 2025 in the condition of ecological protection, 2604049 km2 in the condition of business as usual and 2609125 km2 in cultivated land protection.
