ВЛИЯНИЕ ГИПОТЕНЗИВНЫХ ПРЕПАРАТОВ В ПОСЛЕОПЕРАЦИОННОМ ПЕРИОДЕ У ПАЦИЕНТОВ С ПСЕВДОЭКСФОЛИАТИВНЫМ СИНДРОМОМ НА ФОНЕ ОСЛОЖНЕННОЙ КАТАРАКТЫ

In modern surgery of complicated cataracts, an important factor is the preservation of visual functions with minimal costs. The surgeon’s experience and modern technology, which makes it possible to identify hidden symptoms of certain pathologies at the diagnostic stage, allows for a favorable completion of surgery with minimal intraoperative complications. This article shows the approach and observations of patients at risk of increasing eye pressure in the postoperative period due to the anatomical structures of the eye (in these cases, patients with open-angle glaucoma) to antihypertensive drugs. 131 patients (134 eyes) with various signs of pseudoexfoliation syndrome participated in the observation. Before planned surgery for complicated cataracts, all patients underwent ophthalmological diagnostics, medical history, and laboratory tests according to generally accepted methods. All operations were performed by the same surgeon. Cataract surgery was performed according to the standard technique (Phaco + intraocular lens) through a 2.2 mm incision, two 1.2 mm paracentesis, but for some patients other components of surgical interventions were added. In the observation groups, for better fixation and a lower percentage of complications in long-term follow-up periods, RPR, T-19, Myol were implanted in 27.7%. A large percentage of 34% were implanted with the HO Acrylic IOL model lens, which requires a 2.2 mm corneal incision. In observation groups 2 and 3, 32.5 and 31.8% preferred lenses to the Acrysoft IQ model. And in 32.5% and 13.6%, respectively, the AFY model. The choice of the method of surgical intervention, as well as the model of intraocular lenses, made it possible to predict the long-term postoperative period with less toxicity for the patient’s condition. No intraoperative complications were observed; the administration of antihypertensive drops, both in combination and in monotherapy in the early stages of the postoperative period, allowed maintaining eye pressure within normal limits in all observation groups.

In the digital economy, the use of artificial intelligence is inevitable, including by lawyers. While there is a perception that artificial intelligence will not fundamentally change the practice of law, and that the legal profession requires specialised skills and making judgments in a way that only humans do, the use of technology in the legal sector is and will continue to become more prevalent. While not every problem can be solved by technology, there are fewer and fewer solutions that will not be supported by it in some way. This will increase the role of legal engineers – they will build the future of law, which can be imagined as a collaboration between all members of an organisation, including those with a legal background and those with experience in other fields. The diversity of perspectives encourages innovative thinking, the creation of more efficient service delivery models, and the satisfaction of both service providers and service recipients, while work automation minimises risk and reduces the number of errors by ensuring that the same rules are followed every time. Many lawyers have accepted that technology has and will continue to play a big role in their work, although not all are well equipped to use it. They need new skills, primarily in management, project delivery, finance, marketing, mediation and negotiation, as well as modern technology.

Genomic surveillance strategy. Problems and perspectives

The topic of epidemiologic surveillance is one of the basic concepts in the theory and practice of epidemiologic science. In Russia, generalization of the accumulated factual material and theoretical developments have allowed us to formulate a number of provisions on the nature of the epidemic process. The pandemic of a new coronavirus infection has forced adjustments in all spheres of society, including the activities of the infectious disease epidemiological surveillance system, requiring the development and implementation of innovative solutions. Based on the experience of prompt response to the tasks set by the COVID-19 pandemic, the authors raised the problem of development and implementation of a system of molecular genetic monitoring for pathogens of emerging and re-emerging infections as a priority vector of epidemiological surveillance development. The introduction of modern molecular biological technologies for the identification of pathogens with epidemic potential, taking into account their genetic diversity, into the system of epidemiologic surveillance has been substantiated based on the experience of using platform solutions created by the Central Research Institute of Epidemiology of Rospotrebnadzor. The strategy of genomic epidemiologic surveillance as a powerful tool to ensure readiness for response measures and management of the epidemic process by implementing and adjusting preventive and anti-epidemic measures was developed. The Russian platform for aggregation of information on virus genomes (VGARus) developed at the Central Research Institute of Epidemiology of Rospotrebnadzor as a technological, scientific, organizational and infrastructural base of genomic epidemiological surveillance, acting as an interdepartmental consortium, has been introduced into practice. The efficiency of VGARus was shown to assess the mutational variability of SARS-CoV-2, the influence of evolutionary development of circulating pathogens on the characteristics of the epidemic process, the implementation of operational and retrospective analysis of morbidity and prediction of the spread of genetic variants of pathogens.

Impact of Crop Production on Economic Growth in Nigeria, 1981 – 2018

This study examined the impact of crop production on economic growth in Nigeria utilizing annual time series data from 1981 to 2018. The study used Johansen cointegration test, Vector Error Correction test, the impulse response functions and variance decomposition for data analysis after the data series were checked against unit root problem using the Augmented Dickey Fuller unit root test. The study tested and found that increase in the production of cassava, cocoyam, groundnut, guinea corn, maize, millet, rice and yam spurs economic growth in Nigeria in the long-run except for cotton production and with only groundnut production contributing significantly to the output of the Nigerian economy in the short- run. The study, therefore recommends that the Nigerian government should encourage farmers in the production of crops through supply of fertilizer to increase their productivity and food output while improving their use of modern seedlings and technology in the production that may in turn increase the crop production while farmers should be encouraged to adapt best practices in farming to maximize crop yield.

Watchdog or Lapdog? South African Broadcasting Corporation News in the Coverage of the 2021 Local Government Elections

ABSTRACT The South African Broadcasting Corporation (SABC) post-1994 was transformed into a public service broadcaster, to advance the course of democracy. The SABC newsroom continued to navigate modern technology, although with challenges. Also, the heads of news at the SABC were mainly political deployees who promoted the African National Congress (ANC)-led government's mandate, ignoring the interests of the citizenry. Using the social responsibility theory, this paper argues that the appointment of the new head of news in 2018 revived the SABC’s mandate and the institution performed well in the 2021 local government elections. Drawing on semi-structured interviews with SABC journalists and recorded programmes for news and current affairs for six weeks during the election period, this qualitative study's findings attest that the journalists felt more protected from censorship and political interference, which promoted a culture of ethical performance. However, the SABC newsroom convergence process still appeals to the elite at the expense of its radio platforms. This paper argues that SABC needs to invest more in its radio platforms. Ethical leadership is another crucial ingredient for the SABC to perform its watchdog role, instead of operating as a lapdog of the ANC or politicians from other parties.

THE IMPACT OF USING INTERNAL CONTROL UNDER THE ELECTRONIC OPERATING SYSTEM

Internal control tools constitute one of the modern frameworks approved by the Committee of Sponsoring Organizations (COSO).

The “Boundary” of Technology, Culture, and Digitalization

Human beings use various techniques to change their mode of production and lifeworld. However, modern technology is becoming increasingly self-oriented and is threatening human subjectivity. The digital revolution, with its unprecedented “surpassing” capability, breaks through various boundaries of human social life and, in reality, increasingly escapes from human control. The digital mode of thinking involves both formality and power. When social beings and humanities become products and commodities, and when “artificial humans” such as electronic humans, robots, intelligent humans, and genetic humans can be mass-produced, “natural humans” seem to disappear. The social organizations, lifestyles, ethics, and legal systems that are composed and created by natural beings can no longer be maintained. If humans have always dreamed of enhancing their potential by integrating technology science with social ethics and humanistic values, the building of digital ethics and digital cultural values then becomes a must. And the basis for all of these is to acknowledge and maintain some basic boundaries. The most important one is the boundary between human nature/self and “non-human”—the boundary between human beings and the external world. If human nature resists digitalization, humans will never be “assimilated” by technology. The survival of human beings and the continuation of civilization require a balance among technology, digitalization, humanity, and ethics to secure human subjectivity over technocracy.

Effects of Controlled-release Blended Fertilizer on Crop Yield and Greenhouse Gas Emissions in Wheat-maize Rotation System

The increasing use of nitrogen fertilizers exerts extreme pressure on the environment (e.g., greenhouse gas emissions, GHGs) for winter wheat-summer maize rotation systems in the North China Plain. The application of controlled-release fertilizers is considered as an effective measure to improve crop yield and nitrogen fertilizer utilization efficiency. To explore the impact of one-time fertilization of controlled-release blended fertilizer on crop yield and GHGs of a wheat-maize rotation system, field experiments were carried out in Dezhou Modern Agricultural Science and Technology Park from 2020 to 2022. Five treatments were established for both winter wheat and summer maize, including no nitrogen control (CK), farmers' conventional nitrogen application (FFP), optimized nitrogen application (OPT), CRU1 (the blending ratio of coated urea and traditional urea on winter wheat and summer maize was 5:5 and 3:7, respectively), and CRU2 (the blending ratio of coated urea and traditional urea on winter wheat and summer maize was 7:3 and 5:5, respectively). The differences in yield, nitrogen fertilizer utilization efficiency, fertilization economic benefits, and GHGs among different treatments were compared and analyzed. The results showed that nitrogen application significantly increased the single season and annual crop yields of the wheat-maize rotation system (P < 0.05). Compared with those of FFP, the CRU1 and CRU2 treatments increased the yields of summer maize by 0.4% to 5.6%, winter wheat by -5.4% to 4.1%, and annual yields by -1.1% to 3.9% (P > 0.05). N recovery efficiency (NRE), N agronomic efficiency (NAE), and N partial factor productivity (NPFP) were increased by -8.6%-43.4%, 2.05-6.24 kg·kg-1, and 4.24-10.13 kg·kg-1, respectively. Annual net income increased by 0.2% to 6.3%. Nitrogen application significantly increased the annual emissions of soil N2O and CO2 in the rotation system (P < 0.05) but had no effect on the annual emissions of CH4 (except for in the FFP treatment in the first year). The annual total N2O emissions under the CRU1 and CRU2 treatments were significantly reduced by 23.4% to 30.2% compared to those under the FFP treatment (P < 0.05). Additionally, nitrogen application significantly increased the annual global warming potential (GWP) of the rotation system (P < 0.05), but the intensity of greenhouse gas emissions was reduced due to the increase in crop yields. Compared with that under FFP, the annual GWP under the CRU1 and CRU2 treatments decreased by 9.6% to 11.5% (P < 0.05), and the annual GHGs decreased by 11.2% to 13.8% (P > 0.05). In summary, the one-time application of controlled-release blended fertilizer had a positive role in improving crop yield and economic benefits, reducing nitrogen fertilizer input and labor costs, and GHGs, which is an effective nitrogen fertilizer management measure to promote cleaner production of food crops in the North China Plain.

The synthesis of conventional plastics has increased tremendously in the last decades due to rapid industrialization, population growth, and advancement in the use of modern technologies. However, overuse of these fossil fuel-based plastics has resulted in serious environmental and health hazards by causing pollution, global warming, etc. Therefore, the use of microalgae as a feedstock is a promising, green, and sustainable approach for the production of biobased plastics. Various biopolymers, such as polyhydroxybutyrate, polyurethane, polylactic acid, cellulose-based polymers, starch-based polymers, and protein-based polymers, can be produced from different strains of microalgae under varying culture conditions. Different techniques, including genetic engineering, metabolic engineering, the use of photobioreactors, response surface methodology, and artificial intelligence, are used to alter and improve microalgae stocks for the commercial synthesis of bioplastics at lower costs. In comparison to conventional plastics, these biobased plastics are biodegradable, biocompatible, recyclable, non-toxic, eco-friendly, and sustainable, with robust mechanical and thermoplastic properties. In addition, the bioplastics are suitable for a plethora of applications in the agriculture, construction, healthcare, electrical and electronics, and packaging industries. Thus, this review focuses on techniques for the production of biopolymers and bioplastics from microalgae. In addition, it discusses innovative and efficient strategies for large-scale bioplastic production while also providing insights into the life cycle assessment, end-of-life, and applications of bioplastics. Furthermore, some challenges affecting industrial scale bioplastics production and recommendations for future research are provided.

Photothermal superhydrophobic composite coatings based on n-tetradecane@CaCO3/TiN microcapsules for anti-/deicing

Ice accumulation on equipment and building surfaces is a scientific and modern engineering problem to be solved urgently. Compared to the energy-intensive and expensive active anti-/deicing approaches, passive energy-free technology based on advanced materials and surface engineering has received more attention. Herein, we successfully encapsulated n-tetradecane in calcium carbonate shell by in situ precipitation method, and the microcapsules reveal good energy-storage capability (99.9 %), latent heat (108.1 J g−1), and long-term durability. Combining the microcapsule with low-cost titanium nitride and low-surface-energy PDMS (polydimethylsiloxane) materials, the multifunctional superhydrophobic composite coating has been successfully prepared. The composite coating surface possesses strong absorption in UV–vis-NIR bands with high photothermal conversion and storage capability. The results indicate that the composite coating successfully prolongs the icing time compared to traditional photothermal superhydrophobic surfaces, and accelerates the melting of ice droplets under light illumination, which demonstrates great potential in both anti-icing and deicing applications.
