Authors: VAKULENKO Igor , PROYDAK Svetlana , ASKEROV Hangardas
Published: November 2020

From an analysis of the dependence complex of carbon steel properties on structural parameters, it was found that for an isostructural state, the influence of austenite grain size on impact strength exceeds the dependence on carbon content. As a result of explaining correlation relationships between individual mechanical characteristics, to evaluate critical stress intensity factor, a relationship is proposed based on the use of impact strength. The proportionality coefficient in proposed dependence is determined by ratio of elongation to narrowing at tensile test.
IDENTIFICATION AND RISK ASSESSMENT IN CARSHARING
Authors: HANUSIK Andrzej
Published: November 2020

There are many new concepts for doing business in the modern market. Carsharing is one of such models that are directly related to the sharing economy. The current body of literature shows an absence of reports about risk management in carsharing operators. Further investigation of scientific databases confirms the existence of a research gap in this field. The purpose of this article is for identification of risks in carsharing and their latter assessment in terms of probability of occurrence, impact on customer relationships, the importance of a given category and the cost they generate. A way of aggregating various categories of risks into one synthetic indicator to prioritise them was proposed. The methodology of the process was based on a methodological triangulation which is established on the following studies – analysis and criticism of literature which helps to place discussed research problems on a theoretical basis, qualitative research and observations allowing to identify individual categories of risks and quantitative research enabling the description of given categories of risks by appropriate variables on which further risk modelling is performed. Such research may be a basis for subsequent analysis and an impulse to an academic debate. Besides, it may contribute to the creation of further studies, which deal with the problem of assessment of the risk in concepts related to sharing economy.

Authors: SOATOVA Nodira
Published: November 2020

This article presents the results of the analysis of experimental data on testing of reinforced concrete elements for multiple-repeated loads and field tests of operated span structures. This article proposes dependencies on the definition of deflections during the operation period. Based on the processing of the available experimental data, dependences are proposed for determining deflections under multiple repeated loads, and on this basis, dependences are obtained for predicting the residual life of span elements. The initial data for the calculations are the data on the accumulated residual deflections determined in the process of technical diagnostics.
The role of the hydrocarbon transmission system towards achieving the status of energy superpower in the 21st century
Authors: ŻUKOWSKA Alicja
Published: November 2020

This article aims to introduce the energy policy program assumptions of the Russian Federation. An analysis led to the conclusion that the Russian Federation avails the network of hydrocarbon transmission pipelines to obtain an energy superpower status. The transformation of the energy sector is not restricted to measures aimed at increasing efficiency. It similarly plays a vital role in building the state's potential. More so, it co-creates the crucial instruments of international influence. Through building the network of pipelines, the Kremlin consistently attains its geopolitical aim of being an important player in the international arena. Ineffective endeavours to get out of the Russian domination in that area has allowed Russia to maintain its infrastructure monopoly and dominance of Russian gas on the markets of Central and Eastern Europe.

The prospective of the application of new materials on a polymer base is shown in this work. Given that developed composites can be efficiently used for protection of equipment that is operated at elevated temperatures, the impact of the nature and content of powder mixture, synthesised by high voltage electric discharge, on the thermophysical properties of epoxy composites were studied. Epoxy diane oligomer was chosen as the main component of the binder during the formation of the composites. Polyethylene polyamine hardener was used for cross-linking of epoxy composites, which allows hardening of materials at room temperatures. The selection of powder mixture, synthesised by high voltage electric discharge, for increase of thermophysical properties of developed materials was justified. More so, thermal stability and activation energy of epoxy composites were studied. Permissible limits of the temperature, at which developed materials can be used, were established based on the conducted tests of thermophysical properties of materials, filled by powder mixture, synthesised by high voltage electric discharge.

Essential techniques for fastening loads in road transport
Authors: MACIOSZEK Elżbieta
Published: November 2020

During the transportation of goods, damage and destruction of the transported cargo constitute a very large part of the damage. The most common direct cause of damage is an improper arrangement and securing of the transported load. An improperly secured load may pose a threat to the transporters and bystanders. Incorrectly secured loads can fall from the vehicle, obstruct movement, and cause injury or death. In addition, improperly secured loads can cause injury or death in heavy braking or a collision. The way the load is distributed and secured on the vehicle can negatively affect driving behaviour, making it difficult to control the vehicle. This article presents the conditions related to the transport of loads in road transport, describes both the forces that act on the load during the journey of a vehicle and the most important techniques for securing loads in road transport.

Published: November 2020

Processing performance of hazardous wastes in Indonesia, mainly produced in
mining, energy and mineral industries, is well below target. One suitable technique for
processing such waste is bioremediation which utilize microorganism activities. Waste rice
straw is one potential substrate which carries and supports the bioremediation
microorganisms. Lignin in the straw provides nutrients for bacteria and fungi which enable
the production of enzymes to degrade pollutants in the waste. Lignin can also increase
interfacial surface tension between hydrophobic and hydrophilic fractions in the waste
mixture to facilitate their separation. The objective of this study is to model the kinetic of
bioremediation which represent the relation between bioremediation period and reduction
rate of Total Petroleum Hydrocarbon (TPH). The model utilized characterization results of
retentate from waste filtration in terms of water content and pH. The bioremediation
process involved mixing of waste rice straw and processed liquid waste from a petroleum
refinery plant at 1:20 (m/v) ratio for varied duration of 10, 15, 20, 25, and 30 days. Results
showed that the formation rate of water (measured as moisture content in retentate) which
indicate the reduction rate of TPH follows 1.2 order of reaction at rate constant of 0.594
day-1. Prediction of Michaelis-Menten model was also performed. The pH of retentate was
8, and organoleptic test observed the turning of color from turbid yellow into dark brown as
well as the disappearance of petroleum oil smell, which demonstrated that the processed
waste is safe for the environment.

Published: November 2020

Azo compounds are a very unique class of chemical compounds, drawing
considerations in scientific research. Azo compounds are studied as class of organic colorants
which have at least a conjugated chromophore azo (-N=N-) group in fusion with one or more
aromatic or heterocyclic ring system. Benzimidazole derivatives are privileged intermediates
for the development of molecules of pharmaceutical or biological interest. Benzimidazole
derivatives have gathered wide applications in diverse therapeutic areas such as antiulcer,
anticancer agents, and anthelmintic species to name just a few. Although many azo derivatives
of benzimidazole nucleus has been reported in literature but only few of them have been
evaluated for their biological potencies. This review focuses primarily on those derivatives
which are evaluated as anticancer, antibacterial, antifungal, antitubercular, and other medicinal
agents. This review may be helpful for the investigators on the basis of substitution pattern on
the nucleus with an objective to assist medicinal chemists for developing an SAR on azo
benzimidazoles or similar compounds.

Recurrent Aphthous Stomatitis (RAS) is one of the most common pathological
conditions with ulcers in the oral mucosa. Various conventional medicines are available in the
market for RAS but due to a range of factors people are getting affected by RAS gradually.
More over conventional medicines are all having the side effects so the alternative system for
the treatment of RAS came in to the market. Although herbal medicines are widely used in
India and other countries and multiple studies are conducted in this regard, but still many of
the herbal plants are not utilized though they are having traditional claim. Aim of this is
review is suggesting the herbal plants which are claimed for the treatment of mouth ulcer but
scientifically validated for gastric ulcer by using animal models should also be validated for
mouth ulcer by clinical trials and also which are used traditionally but not yet concentrated can
be evaluated and used for the treatment of RAS.

Hydroxychloroquine And Dexamethasone Are Both Possible
For Treatment Of Covid-19

Published: November 2020

The antimalarial operators chloroquine and hydroxychloroquine have been
utilized generally for the treatment of rheumatoid joint inflammation and fundamental lupus
erythematosus. These mixes lead to progress of clinical and research facility parameters,
however their moderate beginning of activity recognizes them from glucocorticoids and
nonsteroidal mitigating operators. Chloroquine and hydroxychloroquine increment pH inside
intracellular vacuoles and adjust procedures, for example, protein corruption by acidic
hydrolases in the lysosome, get together of macromolecules in the endosomes, and
posttranslation change of proteins in the Golgi mechanical assembly. It is suggested that the
antirheumatic properties of these mixes results from their obstruction with "antigen preparing"
in macrophages and other antigen-introducing cells. Acidic cytoplasmic compartments are
required for the antigenic protein to be processed and for the peptides to collect with the alpha
and beta chains of MHC class II proteins. Thus, antimalarials reduce the arrangement of
peptide-MHC protein edifices required to animate CD4+ T cells and result in down-guideline
of the safe reaction against autoantigenic peptides. Since this system varies from other
antirheumatic drugs, antimalarials are appropriate to supplement these different mixes in blend
medicate treatment[1].

Authors: Hu Xuantao , Chen Xia , Li Tao , Liu Zicheng , Guo Xiaoning , Ouyang Zhengxiao
Published: December 2020

Background: The critical role of arterial infusion chemotherapy in the multimodal treatment of extremity bone cancer has been investigated extensively, but few studies have focused on pelvic osteosarcoma. Therefore, we attempted to evaluate the clinical significance of arterial infusion chemotherapy in the treatment of pelvic osteosarcoma.Methods: We combined a cisplatin arterial infusion regimen with multidrug systematic chemotherapy as a neoadjuvant protocol for the treatment of pelvic osteosarcoma. The course number and dosage of cisplatin arterial infusion were adjusted to achieve a maximal tumor response evaluated by contrast-enhanced MRI per RECIST 1.1. Good responders received the same systematic combination for postoperative chemotherapy, and poor responders received second-line therapy. Twelve patients with nonmetastatic high-grade pelvic osteosarcoma were included. Survival, chemotherapy response and adverse events data were analyzed. Results: The mean follow-up period was 56.1 months. Four patients died of refractory tumor progression, and 1 patient with local recurrence had no evidence of disease for 27 months after receiving secondary amputation and resection. Kaplan-Meier survival analysis demonstrated a 57.8% overall survival and 52.5% event-free survival rate at 5 years. Eight of 12 patients had a >90% tumor necrosis rate according to histopathologic examinations. The rates of local adverse events were lower than those reported for extremity osteosarcoma. Conclusions: Our study initially indicated that the cisplatin arterial infusion regimen was a potential therapy with good tolerance in the treatment of pelvic osteosarcoma.

Six infected fish were observed having eighteen parasites in total with minimum and maximum lengths of 40.23 mm and 51.79 mm, respectively. The prevalence, mean intensity and abundance of infection were assessed as 42.85%, 3 and 1.28 respectively. This study reports the first record of this endoparasite from Anatolian ghizani, a species endemic to South-Western Turkey. This is also the first record of this parasite from Aegean Region that is an evidence of increasing spread of this group in non-infected parts of Turkey mainly through the forced biological invasion.

Authors: TANUR Münüre , YORGANCILAR Mustafa
Published: December 2020

Bu araştırmada, tuz stresine maruz bırakılan kanola (Brassica napus L.) tohumlarına salisilik asit (SA) ve askorbik asit (AsA) ile priming yapılarak çimlenmeye etkilerinin belirlenmesi ve bu uygulamaların optimum konsantrasyonlarının tespit edilmesi amaçlanmıştır. Araştırmada, 5 farklı NaCI konsantrasyonu (kontrol, 50, 100, 150, 200 mM) ile 2 farklı priming uygulaması (SA ve AsA ) ve her priming uygulamasının 5 farklı konsantrasyonu (kontrol, 0.5, 1.0, 1.5, 2.0 mM) ele alınmıştır. Çalışma tesadüf parsellerinde faktöriyel deneme desenine göre dört tekerrürlü olarak yürütülmüştür. Araştırma sonucunda çimlenme oranı (%), ortalama çimlenme süresi (gün) ve çimlenme indeksi (hızı) değerleri incelenmiştir. SA uygulamaları arasında, 0.5 mM SA konsantrasyonunun, artan tuz dozlarında tuz stresinin olumsuz etkisini azaltarak çimlenmeyi hızlandırdığı, ortalama çimlenme süresini kısalttığı ve çimlenme oranını artırdığı tespit edilmiştir. SA konsantrasyonu artıkça (1.5 mM ve 2.0 mM SA) tüm tuz uygulamalarında çimlenmenin olumsuz etkilendiği belirlenmiştir. AsA uygulamaları arasında ise 0.5, 1.0, 1.5 mM konsantrasyonlarının, tuz stresinin olumsuz etkisini büyük ölçüde azaltarak çimlenme oranı ve çimlenme indeksi değerlerine olumlu etkide bulunduğu belirlenirken, ortalama çimlenme süresi üzerine etki etmediği tespit edilmiştir. Kanola tonumlarına çimlenme öncesi uygulanan SA ve AsA ile priming uygulamalarının, tuz stresinin çimlenme engelleyici etkisini önemli ölçüde ortadan kaldırdığı saptanmış olup, 0.5 mM SA/AsA konsantrasyonları optimum doz olarak belirlenmiştir.

Aeromania and Enlightenment: The Politics of Hot Air Balloons in Karamzin's "Letters of a Russian Traveler"
Authors: Baudin Rodolphe
Published: December 2020

This paper focuses on Karamzin’s depiction, in Letters of a Russian Traveler, of Abbé Miolan’s failed hot air balloon flight in Paris in July 1784. After briefly tracing the history of aeromania in late eighteenth-century France and England, as well as its contemporary Russian reception, notably by Catherine the Great, the paper identifies Karamzin’s sources of information on the event and analyses the reasons why the Russian writer mentioned it in his travelogue. It demonstrates that Karamzin’s depiction of a physical experiment embodying European capacity for innovation in the late eighteenth century was not an expression of scientific curiosity. Instead, the young writer used the episode as a metaphor of social and political management, in order to reflect on the questions of social autonomy and the relation of the enlightened public with State power in both France and Russia. By depicting Miolan’s failed flight as a condemnable nuissance to public order, reminiscent of the revolutionary trouble he had witnessed during his journey through France, Karamzin showed his endorsement of Catherine’s conservative conception of the Enlightenment. By depicting how the French public sphere dealt with Miolan and possibly implicitly comparing it with the way Catherine had dealt with Radishchev, he nevertheless showed the superiority of self-regulation over political violence in managing the nobility’s growing longing for autonomy.

BACKGROUND

Psychological problems among children and adolescents have become a public health issue.

OBJECTIVE

This study aimed to investigate associations between screen time (ST), outdoor activity (OA), and emotional and behavioural health problems (EBHPs) among South Chinese children and adolescents

METHODS

Purposive sampling has been adopted from April to May 2019 to conduct a questionnaire survey among 30,188 children and adolescents in grade 1 to 12 from 14 schools in 6 streets in Baoan District of Shenzhen according to the three stages of street - school type - school. EBHPs were measured with the strengths and difficulties questionnaire; OA and ST data were obtained through self-reporting. Descriptive analyses, chi-squared tests, and logistic regressions were performed using SPSS 23.0

RESULTS

In our study, 42.4% students had insufficient OA, 24.2% students had excessive ST, the abnormal of emotional symptoms, conduct problems, peer problems, hyperactivity problems, prosocial behaviour, and total difficulties scales were 18.5%, 6.9%, 6.4%, 13.1%, 10.7% and 8.8%. There were significant associations between ST/PA, independently and through interaction, and EBHPs among children and adolescents. Participants with high exposure to ST were more likely to have EBHPs than those with low exposure; participants with low exposure to PA were also more likely to have EBHPs than those with high exposure. The interactive associations of ST and PA on EBHPs were stronger than those of ST or PA individually.

CONCLUSIONS

Our results show positive associations between ST, OA, and EBHPs. They indicate that interventions should be considered for decreasing ST and increasing OA in children and adolescents.
UJI RESISTENSI GENOTIPE TERPILIH DARI PLASMA NUTFAH IRRDB TERHADAP PENYAKIT GUGUR DAUN CORYNESPORA DENGAN METODE CAKRAM DAUN

Corynespora cassiicola (Berk & Curt) Wei adalah jamur penyebab penyakit gugur daun yang menginfeksi daun muda dan daun tua, dan dapat mengakibatkan daun karet gugur sepanjang tahun, sehingga menyebabkan tertundanya matang sadap, produksi lateks menurun pada tanaman menghasilkan, dan bahkan pada klon yang sangat rentan dapat mematikan tanaman. Seleksi terhadap berbagai genotipe karet sejak awal sangat penting untuk mengetahui tingkat ketahanannya terhadap penyakit. Pada penelitian ini dilakukan uji resistensi 29 genotipe terpilih dari plasma nutfah IRRDB terhadap penyakit gugur daun C. cassiicola, menggunakan Rancangan Acak Lengkap (RAL) faktorial dengan 60 perlakuan kombinasi dan 2 ulangan. Pengujian dilakukan  terhadap isolat dari Sumatera Utara dan Aceh dengan klon PB 260 sebagai pembanding (kontrol). Semua genotipe diinokulasikan pada setiap isolat C. cassiicola dengan menggunakan metode cakram daun dan penilaian intensitas serangan penyakit diklasifikasikan dalam kategori resisten (0–20%), agak resisten (21–40%), moderat (41–60%), agak rentan (61–80%), dan rentan (81–100%). Hasil penelitian menunjukkan bahwa terdapat perbedaan resistensi genotipe plasma nutfah IRRDB terhadap isolat dan kontrol. PB 260 yang merupakan klon yang tergolong resisten terhadap kedua isolat. Genotipe PN 386, PN 398, PN 807, PN 5666, PN 5730, dan PN 5808 tergolong moderat terhadap isolat Sumatera Utara tetapi agak resisten terhadap isolat Aceh. Genotipe PN 803 tergolong agak rentan terhadap isolat Sumatera Utara dan moderat terhadap isolat Aceh sedangkan genotipe lainnya tergolong agak resisten terhadap kedua isolat. Isolat yang berasal dari Sumatera Utara mempunyai tingkat virulensi yang lebih tinggi dibandingkan dengan isolat yang berasal dari Aceh.  How to Cite : Daslin, A., Fairuzah, Z., & Dalimunthe, C. I.

The Role of the Elites in Choosing the Foreign Policy Priorities of the Baltic States
Authors: Smirnov Vadim A.
Published: December 2020

The author analyzed the role of the elites of the Baltic countries in the choice of foreign policy priorities in the period after the declaration of independence. The process of determining the course towards the Euro-Atlantic is inscribed in the sub-regional context, taking into account the current Russian-Baltic political interaction. The study of power groups was carried out on the basis of an examination of large-scale socio-political transformations along with an analysis of individual practices. A comprehensive study of the transformation of the political elites of Baltic states as small countries, involves consideration of both the domestic and foreign policy aspects. The thesis is put forward that, despite a number of differences in the Baltic states, since the 1990s there were similar processes of transformation of political elites. The elite formation was due to the principle of state continuity as continuity with the pre-war regimes of Latvia, Lithuania and Estonia and as a break with the Soviet period, including the EuroAtlantic course as the key priority of the foreign policy. The consolidation of deep divisions in the societies of the Baltic states - ethnic, linguistic, political - was the result of the elite struggle for power in the 1990s. After the implementation of the idea of Back to the West the elites of the Baltic states replaced it with a Russian threat, which made it possible to postpone overcoming internal divisions fraught with weakening of their power.

Reception of V.S. Solovyov's Legacy in Russian Religious and Philosophical Thought: G.V. Florovsky's Case
Authors: Chernyaev Anatoly V.
Published: December 2020

Public interest in the legacy of Russian religious philosophy, and above all in the legacy of V. S. Solovyov, reached its peak at the turn of the 1990s, after which it declined. As indirect evidence of this, we can note the remaining unrealized idea of installing a monument to the philosopher, slowing down the pace of work on the release of a complete collection of his works, and reducing the number of works dedicated to him. The year of the centenary since the death of Solovyov (2000) was symptomatic, when the authoritative representatives of the Russian philosophical community, S.S. Khoruzhiy and P.P. Gaidenko made an ambiguous assessment of Solovyov's ideological heritage and its significance for the subsequent development of Russian socio-philosophical and religious-theological thought. In the article the statement that the genealogy of the critical interpretation of Solovyov's legacy goes back to the works of the philosopher and theologian G.V. Florovsky is substantiated. Florovsky influence in Russian studies, as well as in post-Soviet Russia in general is difficult to overestimate. In this regard, the author draws attention to the ideological evolution of Florovsky, which gives the key to his interpretation of Solovyov's philosophy. The analysis showed that Florovsky's critical reinterpretation of Solovyov's legacy had both a theoretical, theological, and doctrinal character, and was caused by certain socio-psychological factors related to the generational conflict between representatives and heirs of the Russian religious and philosophical Renaissance of the early XX century. It is demonstrated that the reception of Solovyov by Florovsky was very significant, influential and archetypal for Russian religious and philosophical thought, both in Russia and abroad.
