    The emergence of a new kind of discourse on the world stage called media discourse or media discourse produces the trends of globalization and the development of communication technologies in the world. The article deals with the phenomenon of English-language media discourse as a relatively new linguistic phenomenon. The aim of this research work is a thorough analysis of the concept of English-language media discourse, reflecting the dynamics of modern language and identifying the features of lexical innovations in English-language media discourse. The comparative analysis method, typological method, method of component analysis, and descriptive method of research were used to study the issue of English-language media discourse. Using the comparative analysis method, the saturation of linguistic innovations and their prevalence were determined. Using the typological method, the common qualities of English and Ukrainian in the projection on their variety of linguistic characteristics were established. The method of component analysis helped in the study of the content part of the newly formed linguistic units. Using the descriptive method, the modern state of English-language media discourse was characterized. As a result of the scientific research trends of modern English-language media discourse in content and form have been studied and analyzed, as well as changes in the potential of modern linguistic means through the mechanism of new word formation, which is a prospect for further scientific research in this direction

    Long-term ozone measurements of two background mountain sites, namely the Kislovodsk High Mountain Station in Caucasus, Russia (KHMS, 43.70° N, 42.70° E, 2070 m a.s.l.) and the Jungfraujoch in Switzerland (JFJ, 46.55° N, 7.98° E, 3580 m a.s.l.) are compared. Despite of more than 1.5 km altitude difference ozone mixing ratios are comparable at JFJ an KHMS in the beginning of measurements (1990–1993) while the annually averaged levels at JFJ are around 15 ppb higher than the ones at KHMS for the most recent years (1997–2006). The seasonal cycle of the surface ozone mixing ratios is characterized by a double spring-summer maximum at both sites with a spring one being more pronounced for the air masses with the longest contact with the upper free troposphere and stratosphere. Ozone mixing ratio increased at JFJ but decreased at KHMS for the period 1990–2006. Trends are more pronounced for the 1990s (+0.73±0.20 ppb/year at JFJ and −0.91±0.17 ppb/year at KHMS for the period 1991–2001) in comparison with the later years (+0.04±0.21 ppb/year at JFJ and −0.37±0.14 ppb/year at KHMS for the period 1997–2006). Trends show a distinct seasonality, which is different for the different periods. To investigate possible reasons for this remarkable trends difference 3-D trajectories using LAGRANTO trajectory model are used. Effects of horizontal and vertical transport on ozone trends are considered. No substantial systematic changes in the transport patterns were detected which could lead to strong changes in the trend magnitude between 1991–2001 and 1997–2006. The geographical position of the sites relative to the main topographic features and emission sources as well as distance from the coast are interpreted to be among the main reasons for the opposite surface ozone trends. During the 90s the JFJ trend reflects increase of the ozone in the upper free troposphere/lower stratosphere, while KHMS is not sensitive to this change or even showing the opposite tendency. The analysis provided evidence for a stronger influence of processes in the lower troposphere, in particular the dramatic emission decrease in the earlier 1990s in former USSR and emissions regulations in Western Europe on the surface ozone trend at KHMS.ISSN:1680-7375ISSN:1680-736

    Background: Given the urgency of the problem of clinical and experimental pathology of diabetes mellitus (DM) and the reproductive function disorders and their correction, the direction of research was determined in the following way: to establish the functional state of testicular cells and appendages under experimental hyperglycemia, and to assess future prospects for gold nanoparticles for clinical trials. The aims to evaluate the effect of five times treatment with gold nanocomposites (gold nanoparticles (AuNPs) in the polymer matrix D-g-PAA(PE) on male reproductive function under conditions of experimental hyperglycemia.Methods: Experiments (two series) have been conducted on 120 (60 males and 60 females) Albino white laboratory mice (weighing 25-30 gm). Experimental hyperglycemia, a model of type 2 diabetes mellitus (DM2) was reproduced by administration of nicotinamide and streptozotocin (internally peritoneally). The treatment of substances was carried out in the following way: D-g-PAA (PE) (10.00 mg/kg), D-g-PAA (PE)/AuNPs (9.78 mg/kg) in the tail vein, in 0.3 ml, once a day, five times, 2 weeks after EG induction once a day, five times.Results: it was established for the first time that there is disorder of male reproductive function under conditions of experimental hyperglycemia and five-fold treatment of gold nanocomposites (D-g-PAA(PE)/AuNPs, namely an increase in the number of abnormal sperm and a decrease in spermatids, as well as an increase in preimplantation mortality of embryos (compared to this value under experimental hyperglycemia).Conclusions: Our new data suggest that treatment with such gold nanocomposites (gold nanoparticles in D-g-PAA (PE) polymer matrix) are not critical for therapeutic use (in photodynamic chemotherapy), even in hyperglycemia when there is diabetes

    The Global Atmosphere Watch reactive gases measurement network

    Long-term observations of reactive gases in the troposphere are important for understanding trace gas cycles and the oxidation capacity of the atmosphere, assessing impacts of emission changes, verifying numerical model simulations, and quantifying the interactions between short-lived compounds and climate change. The World Meteorological Organization’s (WMO) Global Atmosphere Watch (GAW) program coordinates a global network of surface stations some of which have measured reactive gases for more than 40 years. Gas species included under this umbrella are ozone, carbon monoxide, nitrogen oxides, and volatile organic compounds (VOCs). There are many challenges involved in setting-up and maintaining such a network over many decades and to ensure that data are of high quality, regularly updated and made easily accessible to users. This overview describes the GAW surface station network of reactive gases, its unique quality management framework, and discusses the data that are available from the central archive. Highlights of data use from the published literature are reviewed, and a brief outlook into the future of GAW is given. This manuscript constitutes the overview of a special feature on GAW reactive gases observations with individual papers reporting on research and data analysis of particular substances being covered by the program. - See more at: http://elementascience.org/article/info:doi/10.12952/journal.elementa.000067#sthash.cHvHu0T6.dpu

    Ship-based contributions to global ocean, weather, and climate observing systems

    The role ships play in atmospheric, oceanic, and biogeochemical observations is described with a focus on measurements made within 100 m of the ocean surface. Ships include merchant and research vessels, cruise liners and ferries, fishing vessels, coast guard, military, and other government-operated ships, yachts, and a growing fleet of automated surface vessels. The present capabilities of ships to measure essential climate/ocean variables and the requirements from a broad community to address operational, commercial, and scientific needs are described. Following the guidance from the OceanObs'19 organizing committee, the authors provide a vision to expand observations needed from ships to understand and forecast the exchanges across the ocean-atmosphere interface. The vision addresses (1) recruiting vessels to improve both spatial and temporal sampling, (2) conducting multi-variate sampling on ships, (3) raising technology readiness levels of automated shipboard sensors and ship-to-shore data communications, (4) advancing quality evaluation of observations, and (5) developing a unified data management approach for observations and metadata that meets the needs of a diverse user community. Recommendations are made focusing on integrating private and autonomous vessels into the observing system, investing in sensor and communications technology development, developing an integrated data management structure that includes all types of ships, and moving towards a quality evaluation process that will result in a subset of ships being defined as mobile reference ships that will support climate studies. We envision a future where commercial, research, and privately-owned vessels are making multivariate observations using a combination of automated and human-observed measurements. All data and metadata will be documented, tracked, evaluated, distributed, and archived to benefit users of marine data. This vision looks at ships as a holistic network, not a set of disparate commercial, research, and/or third-party activities working in isolation, to bring these communities together for the mutual benefit of all
