In the article, the author considers the verification issue of the endurance of the venture elements of steel-reinforced concrete spans of bridges, in particular, flexible dowel crutches («Nelson’s anchors»). According to the existing domestic regulatory framework, the endurance test of the flexible dowel crutches for road bridges is not required; at the same time, the survey’s results of the operated superstructures indicate the presence of problems associated with the insufficient endurance of these elements. The article presents comprehensive (qualitative and quantitative) comparative analysis results of the world’s existing approaches to testing the endurance of the venture elements. At the stage of qualitative analysis, the author considered methods of checking the endurance of elements in general according to the norms of 8 countries and regions (Russia, the European Union, the USA, Ukraine, Australia, Canada, Japan, China) and highlighted a basic set of methods for checking the endurance of the venture elements (Russia, the European Union, USA, Ukraine). The models of the basic set were subjected to a detailed qualitative analysis according to the criteria of the models used and the parameters included in them. The quantitative analysis of the selected basic set techniques, carried out in relation to the existing bridge, included an analysis of the effects of moving loads on the venture elements, direct elements verification using the considered methods, as well as the design damage comparison of the elements obtained by the Palmgren-Miner linear summation hypothesis. Based on the obtained values of design damage, the values of the use of endurance reserves were determined and analyzed for each of the considered methods and the conditional load model. Based on the results of the qualitative and quantitative analysis, the author draws conclusions based on the comparison of various methods and highlights the rational directions for improving the existing domestic methodology.

Ukrainia Remains of huge importance to Russian Strategy because of its Strategic importance. For being a privileged Postion in new Eurasia, without its existence there would be no logical resons for eastward Expansion by European Powers.  As well as in Connection with the progress of Ukrainian is no less important for the USA (VSD, NDI, CIA, or pentagon) and the European Union with all organs, and this is announced by John Kerry. There has always ben Russian Fear and Fear of any move by NATO or USA in the area that it poses a threat to  Russians national Security and its independent role and in funence  on its forces especially the Navy Forces. There for, the Crisis manyement was not Zero sum game, there are gains and offset losses, but Russia does not accept this and want a Zero Sun game because the USA. And European exteance is a Foot hold in Regin Which Russian sees as a threat to its national security and want to monopolize control in the strategic Qirim.

Crataegi folium have been used as medicinal and food materials worldwide due to its pharmacological activities. Although the leaves of Crataegus songorica (CS), Crataegus altaica (CA) and Crataegus kansuensis (CK) have rich resources in Xinjiang, China, they can not provide insights into edible and medicinal aspects. Few reports are available on the qualitative and quantitative analysis of flavonoids compounds of their leaves. Therefore, it is necessary to develop efficient methods to determine qualitative and quantitative flavonoids compounds in leaves of CS, CA and CK. In the study, 28 unique compounds were identified in CS versus CK by qualitative analysis. The validated quantitative method was employed to determine the content of eight flavonoids of the leaves of CS, CA and CK within 6 min. The total content of eight flavonoids was 7.8–15.1 mg/g, 0.1–9.1 mg/g and 4.8–10.7 mg/g in the leaves of CS, CA and CK respectively. Besides, the best harvesting periods of the three species were from 17th to 26th September for CS, from 30th September to 15th October for CA and CK. The validated and time-saving method was successfully implemented for the analysis of the content of eight flavonoids compounds in CS, CA and CK for the first time.

AbstractThe aim of this systematic review was to perform qualitative and quantitative analysis on the toxic effects of chloroquine (CQ) and hydroxychloroquine (HCQ) on skeletal muscles. We designed the study according to PRISMA guidelines. Studies for qualitative and quantitative analyses were selected according to the following inclusion criteria: English language; size of sample (> 5 patients), adult (> age of 18) patients, treated with CQ/HCQ for inflammatory diseases, and presenting and not presenting with toxic effects on skeletal muscles. We collected data published from 1990 to April 2020 using PubMed, Cochrane Library, EMBASE, and SciELO. Risk of bias for observational studies was assessed regarding the ROBIN-I scale. Studies with less than five patients (case reports) were selected for an additional qualitative analysis. We used the software Comprehensive Meta-Analysis at the confidence level of 0.05. We identified 23 studies for qualitative analysis (17 case-reports), and five studies were eligible for quantitative analysis. From case reports, 21 patients presented muscle weakness and confirmatory biopsy for CQ/HCQ induced myopathy. From observational studies, 37 patients out of 1,367 patients from five studies presented muscle weakness related to the use of CQ/HCQ, and 252 patients presented elevated levels of muscle enzymes (aldolase, creatine phosphokinase, and lactate dehydrogenase). Four studies presented data on 34 patients with confirmatory biopsy for drug-induced myopathy. No study presented randomized samples. The chronic use of CQ/HCQ may be a risk for drug-induced myopathy. There is substantiated need for proper randomized trials and controlled prospective studies needed to assess the clinical and subclinical stages of CQ/HCQ -induced muscle myopathy.

The European Union has grown up in terms of influence and size in international politics. The size of its economy and the ever-increasing membership, have seen its ambitions grow meaning that the EU now has an international presence it did not have at its formation. It is easy to say that with the EU being an ambitious actor in international politics, the rise into prominence of climate change naturally came in handy for the EU as it provided an opportunity for the EU to assert itself and prove both its capacity and presence. The 1992 Rio Earth Summit and the withdrawal of the USA from the obligations of the Kyoto came as a blessing in disguise for the Union as it seized the moment to assert itself. Thus, in trying to understand what role the EU has or is playing in international climate change politics, there is need to assess its leadership claims and what it has done to prove these claims. To get there, the paper will navigate through a part of the discipline of International Relations (IR) to understand how it provides for a basis to explain or understand the EU’s limitations and strengths on actorness.

This article examines Russia’s vision of the European Union’s energy diversification projects that focus on their ‘shared neighbourhood’. It argues that although the European Union (EU), unlike the USA, is not yet seen as a serious threat to Russian interests in the area, this situation is rapidly changing, with the Kremlin becoming increasingly sensitive about the EU’s plans to diversify energy supply sources and transportation routes by increasing cooperation with other former Soviet Republics within the Commonwealth of Independent States (CIS). The article highlights how the EU’s energy diversification projects are viewed by Moscow as anti-Russian and details the way in which Russia is responding to this perceived threat, including plans to diversify its own energy exports.

Despite the crisis, the economy of the European Union remains to be the largest in the world. The economic mechanism of the EU is rather differentiated. It has a great historical experience and possesses sufficient evolutionary robustness. Currently, the former relationships between the EU and the USA undergo substantial changes and new forms emerge. For both of them the greatest challenge is presented by China which in recent decades shows the solid rates of GDP growth. Supposedly, Chines economy will become the world largest on in the new future. Under such conditions the Old World has to conduct a persistent search for new sources of its successful macroeconomic growth.
