The physico-chemical regularities of polypropylene microfibers obtained via processing polypropylene/copolyamide (PP/CPA) mixture melts filled with nanosilicas have been investigated. It has been shown that the chemical nature of silica functional groups affects the viscosity of PP/CPA melts. In spite of the solid state of additives the filling effect does not occur or reveals weakly. Silicas do not prevent the polypropylene fiber-forming in a copolyamide matrix but improve it. This is explained by the stabilizing action of silica additives on PP liquid streams. Nanofilled polypropylene microfibers with diameters 0.30–0.15 μm have been obtained.

A study of the process of activation of molybdenumboride catalyst in the reaction of epoxidation of octene-1 with tert-butyl hydroperoxide and the effect on this process of the initial concentration of octene-1, tert-butyl hydroperoxide and the amount of catalyst in the reaction mixture. As well as reaction products (tert-butyl alcohol and epoxy). It is shown that over time a new amorphous phase is formed on the surface of Mo2B, which actually catalyzes the epoxidation reaction of octene-1 with tert-butyl hydroperoxide. The formation of this phase is the reason for the acceleration of the rate of consumption of hydroperoxide and the selectivity of the formation of epoxide over time.

Published: November 2020

The influence of synthesis conditions on saturation magnetization and coercive force of NiCo ferrites, which were obtained under the action of low-temperature contact nonequilibrium plasma (PNP), is investigated. The main influencing factors were the initial pH of the solution, the treatment temperature and the duration of plasma treatment. Mathematical equations adequately describe the obtained dependences. The results showed that the pH of the reaction medium is the parameter that most affects the magnetic hysteresis for samples obtained by processing KNP. Increasing the initial pH leads to an increase in coercive force.

K.P. Pobedonostsev and V.V. Rozanov: “Fathers and Sons” of Russian Conservatism
Authors: Polunov Alexander Yu.
Published: November 2020

The article is devoted to the analysis of the relations of two major representatives of Russian conservatism of the 19th–20th centuries, – the Ober-Procurator of the Most Hole Synod K.P. Pobedonostsev and publicist V.V. Rozanov. According to the author of the article, those relations revealed not just the personal specifics of both conservatives who initially sympathized with each other both personally and conceptually, but more the principle separation in the conservative camp that happened at the turn of the 19th and 20th centuries. It reflected both the generational and ideological contradictions in the views. In particular, the young conservatives of the turn of the century challenged the “protective” position of K.P Pobedonostsev demanding more efficient activity of the Church and the State in defending the basics of the existing order. Ideologically the new generation of conservatives believed that under the conditions of the ideological struggle aggravations at the turn of the century the conservative fundamentals need to be more clearly formulated and substantiated, while the Ober-Procurator definitely opposed such steps. In the long run those contradictions resulted in tragic consequences for both the conservatism as social and political trend in Russia, and for the destiny of Russian state system in the 20th century.

The Issue of Human Individual in Contemporary Russian Philosophy
Authors: Rostova Natalya N.
Published: November 2020

The article analyzes the current state of affairs in Russian philosophy in connection with the question «What is a human individual?». While distinguishing the terms “Russian philosophy” and “Russian-language philosophy”, the author points out the primordial metaphorical nature of Russian philosophy, its attempt to discover the ineffable in the language, which is characteristic of Rozanov's style of writing. Today this is expressed in the interest of Russian philosophy to the issue of the “literal” and “clip”. In contrast to the European philosophy that interprets itself as ontology, Russian philosophy perceives itself as anthropology. The apophatic and literal language seems to be the most adequate one for the description of the phenomenon of “the human individual”. While the Western philosophy eliminates today the issue of a human individual and transforms anthropological knowledge into non-human anthropology, the Russian philosophy qualifies the human situation as an anthropological catastrophe. Meeting the challenges of this catastrophe, Russian philosophy formulates a number of anthropological projects, which are analyzed in detail in this article. These projects are united under the title of post-cosmism, which opposes the post-humanistic tendencies of Western philosophy. Post-cosmism sees the truth of the human nature in its extension and exceeding its own bounds. It is not the reduction to the world of things, but the transcendence of self that opens up the true horizon of a human being.

Right-Wing Parties in Odessa in 1904 –1917
Authors: Omeliyanchuk Igor V.
Published: November 2020

The article examines the creation, social structure, quantity, financing and main activity directions of the monarchist organizations in Odessa in 1904 – 1917. Odessa became one of the centers of the monarchist movement in Russia, in the period under consideration there were about ten right-wing organizations in the area, some of them being subsidiaries of the all-Russia parties, and some – independent parties. High degree of the city population politicization was conditioned by sharp interethnic and economic contradictions and became the cause of mass monarchic movement, while mixed social structure and personal conflicts among monarchist leaders promoted the split of active monarchist organizations in Odessa and the appearance of the new ones. Right-wing parties in Odessa played a prominent role in the public and political life of the city, especially in 1906 -1912. Then due to various reasons this influence started to decrease. With the beginning of the First World War the monarchist movement in Odessa experienced certain growth. However, the draft of right-wing activists to the army filed forces, the decrease of monarchist ideas popularity in society, as well as social and economic difficulties of the war time, very soon led to the critical weakening of the right organizations in Odessa, followed by their disappearance from the political arena in February of 1917.
“The Actual Population of Kiev… Stays Neutral”: Russian Monarchists and Bolshevistic-Ukrainian Confrontation (January of 1918)
Authors: Chemakin Anton A.
Published: November 2020

The article is devoted to the viewpoint of Russian monarchists in Kiev who were caught in the crossfire of the Ukrainians and the Bolsheviks fighting with each other. One of the leaders of the “Russian Party” in Kiev V.V. Shulgin tried to enter into a tactical alliance with the Ukrainians in the person of S.V. Petliura in order to resist the advancing Bolshevist forces, but the negotiations collapsed. In the long run the main structures of the Russian movement, as well as the majority of the Russians in Kiev did not participate in the conflict of the Ukrainians and the Bolsheviks. And though the myth of the Black Hundreders participating in the Bolshevistic uprising at “Arsenal” plant was not confirmed, a certain part of the former members of workers’ monarchist unions most probably joined the rebels. The author comes to the conclusion that in the beginning of 1918 in Kiev the political groups that later confronted each other in the Civil War, were not finally formed, so there occurred certain tactical unions that were hardly imaginable in the later years.
Historiosophy of N.E. Markov: the Biblical Foundations and Conceptual Discoveries
Authors: Darenskiy Vitaliy Yu.
Published: November 2020

The article examines the historiosophy of N.E. Markov (1866–1945) in the context of its biblical foundations and its conceptual discoveries, that allow us to reveal the “mechanisms” of the revolutions organization and Christian civilization destruction. It is shown that the return to the biblical and patristic understanding of history makes it possible to conceptualize the main spiritual forces of the world-historical process. The “mechanism” of revolutions organizing consists in creating organizational structures that are parallel to the state structures and are capable of paralyzing their functioning at the proper moment. The basis of the “dark forces” activity in history lies first in the elite consciousness manipulation and then – in the broad masses of population consciousness manipulation, which destroys the Christian worldview. According to N.E. Markov, the revival of Russia is possible only within the framework of real monarchy, since all other forms of government are manipulative forms of the “dark forces” dictatorship.

Authors: Gantsev Sh. Kh. , Yun V. , Zhumagulova A. K. , Arybzhanov D. T. , Tursumetov D. S.
Published: November 2020

Introduction. Kidney cancer remains an urgent problem in modern oncology. More than 200 thousand new cases of kidney cancer are diagnosed globally every year, with about 100 thousand patients dying. 15–17% of patients are diagnosed with stage IV kidney cancer. Arterial tumour embolization and nephrectomy are used as a palliative treatment.

Aim. To evaluate the results of renal artery embolization in combined treatment of stage IV kidney cancer.

Material and methods. The treatment results of 22 patients with stage IV kidney cancer are presented: 6 patients had metastases in the skeletal bones; 15 — metastases in the lungs; 1 — bilateral kidney damage. At the first stage, all patients underwent renal artery embolization. Subsequently, 6 patients received bisphosphonates and radiation therapy for metastases in the skeletal bones, 15 patients underwent operation followed by a targeted therapy with Sunitinib and Sorafenib), 1 patient with bilateral kidney damage underwent operation followed by a 2-year targeted therapy with Sorafenib.

Results and discussion. Renal artery embolization was performed successfully without technical difficulties in all the patients. After embolization, hemostasis was achieved in all patients with hematuria (n = 14). Postembolization syndrome was noted in 13 patients with total renal artery embolization. 6 patients with metastases in the skeletal bones lived for 16.4 ± 2.1 months, the survival time of 15 patients who received renal artery embolization, nephrectomy and targeted therapy was 41.7 ± 15.3 months. Only one patient (bilateral kidney damage) has been under dynamic observation for the period of 10 years.

Conclusion. Renal artery embolization is an effective and minimally invasive technical procedure that should be used in the combined treatment of patients with kidney cancer. The combined use of renal artery embolization and subsequent targeted therapy for kidney cancer provide new opportunities for stage IV combined treatment.

Published: November 2020

Introduction. Hepatocellular carcinoma (HCC) is the most common primary malignant neoplasm of the liver. During the early stages, HCC is asymptomatic, which makes X-ray examination a particularly important diagnostic tool. According to WHO data, the mortality rate from HCC was 782,000 in 2018. HCC is associated with a number of risk factors: a high viral load, liver cirrhosis, detected HBeAg and elevated serum HBsAg levels. Inhibitors of tyrosine kinase receptors increase the overall survival and progression-free survival rates in patients with metastatic HCC. In this article, we conduct an analysis of results of the REFLECT study obtained for Russian patients by the Republican Clinical Oncological Dispensary, Ufa.

Materials and methods. The experimental group included 9 patients (52.9%) receiving Lenvatinib. The control group included 8 patients (47.1%)) underwent therapy with Sorafenib at a dose of 800 mg per day 7 (41.17%) patients had a history of chronic hepatitis, of which hepatitis B and chronic hepatitis C was confirmed in 6 and 1 cases, respectively.

Results and discussion. Over the period from 2017 up to the present, progression-free survival was observed in three patients (17.6%), of which 2 and 1 received Lenvatinib and Sorafenib, respectively. Overall survival was 10.5 months. The median overall survival rate in the experimental and control groups was 9.8 and 11.2 months, respectively. These parameters are considered comparable, provided that the sample was small.

Conclusions. The use of Lenvatinib demonstrated the efficacy comparable to that of Sorafenib in terms of the overall survival rate in patients with inoperable HCC. Lenvatinib allowed statistically and clinically significant improvement in the progression-free survival and time to progression to be achieved.

Published: November 2020

The incidence of skin cancer in Indonesia reaches 6-8%, so the skin needs effective protection. Zinc Oxide (ZnO) is a sunscreen with Sun Protecting Factor (SPF) 50 which is able to reduce exposure to Ultraviolet rays. ZnO is difficult to dissolve in water making an obstacle if dispersed in a hydro gel matrix, so it is formulated into a Self-Nanoemulsifying Drug Delivery System (SNEDDS) preparation. SNEDDS formula was made using tween 80 as surfactant, propylene glycol as a co-surfactant, and olive oil. The optimum proportion of the three components was optimized with the D-Optimal method using Design Expert Stat-Ease 9 Trial software. Software obtained 16 formulas which were tested for physical stability response: transmittance value (%) and pH value. SNEDDS optimum formula was compared with the D-Optimal prediction formula using the student's t-test statistical analysis (p>0.05), the loading dose of ZnO, Particle Size Analysis, and Zeta Potential. The optimum proportion of propylene glycol, tween 80, and olive oil making up SNEDDS were 9.9%: 81%: 9.1% respectively. The result of the percent transmittance response was 92.30% and the pH value was 7.20. Software prediction results: transmittance value was 92.59% and pH value was 7.37. Statistical analysis of one sample t-test showed no difference between observations and D-Optimal predictions. SNEDDS was able to load 2.0 mg ZnO/gram SNEDDS with a particle size of 150.2 nm; polydispersity index of 0.54 and zeta potential of -28.50 mV. The SPF value of SNEDDS ZnO was 16.

Published: November 2020

Nicotine, the active compound in cigarettes, can cause impaired glucose metabolism by increasing insulin resistance as well as decreasing insulin secretion in β cell pancreas. This condition can increase the risk of type 2 diabetes in human. This study aims to evaluate the effect of smoking behaviour, determined by Cigarette per Day (CPD) and smoking duration, on glychohemoglobine (HbA1c) levels of Javanese Indonesian smokers. 30 smokers were studied consisting of 7 smokers with <10 CPD, 19 smokers with 11-20 CPD and 4 smokers with 21-30 CPD. They had been smoking for more than 10 years. The whole blood sample was used to examine the HbA1c levels. The HbA1c levels were tested at Bethesda Hospital's clinic laboratories using Architect 600 instrument. The results showed that CPD and smoking duration significantly influenced HbA1c, in which F count was > F table (370.541> 3.354) with significance < 0.05 (2.35. 10-20 < 0.05) and multiple correlation coefficient (R) of 0.982. Therefore, based on this research finding, it was concluded that longer smoking duration and higher CPD caused higher smokers’ HbA1c level.

Ölçek 23 madde ve 5 faktörlü bir yapıdadır. Elde edilen veriler demografik değişkenler ve teknolojiye erişim ile ilgili belirlenen değişkenler açısından incelenmiştir. Veri analizi sonucunda öğretmen adaylarının dijital vatandaşlık düzeylerinin demografik değişken olarak belirlenen cinsiyet ve öğrenim görülen bölüme göre anlamlı şekilde farklılaştığı ancak sınıf, yaş aralığı ve gelir düzeyine göre anlamlı bir fark-lılık bulunmadığı belirlenmiştir. Öğretmen adaylarının bölüm açısından dijital vatandaşlık düzeylerinin birbirine yakın ve yüksek olması alanyazın açısından önemli bir bulgudur. Öğ-retmen adaylarının dijital vatandaşlık düzeyleri teknolojiye erişim olanakları değişkeni açısından incelendiğinde dijital vatandaşlık düzeylerinin bilgisayar sahibi olma, bilgisayar kullanma süresi (yıl bazında), en sık kullanılan sosyal ağda geçirilen süre, e-devlet şifresi sahibi olma ve etkin bir e-posta adresi kullanma açısından anlamlı şekilde farklılaştığı sonucu-na ulaşılmıştır. Ancak öğretmen adaylarının dijital vatandaşlık düzeylerinin internet kullanma sürelerine göre anlamlı şekilde farklılaşmadığı belirlenmiştir.

The purpose of these study is to determine the effect of active compound from tombili seed extract as a vegetable pesticide in the prevention of soil pest in rice plants. The method of these researches is isolation to obtain pure isolates, characterization by using infrared spectrophotometer (IR) and UV-VIS spectrophotometer then following biological test. The isolates obtained were tested positive for phytochemical containing alkaloid compounds and characterized as amorphous crystals. Identification of IR spectrophotometer generate a functioning -NH wave group of the wavelengths region of 3423.4 cm-1, bend C-N at wave number 1242.1 cm-1, C-H stretch at wave number 2925.8 and 2854.5 cm-1, bend C-H at 1475 wave numbers 1540 cm-1, carbonyl group (C = O) at the 1720.4 cm-1 wave number which is probably an alkaloid compound. The UV-VIS spectrophotometer results in a maximum absorption at 209.9 nm wavelengths indicated the presence of double bonds between the C = O functional group suspected as a result of the successive electronic transitions to n-π * and n-σ *. The result of biological test showed that methanol extracts of tombili seed can be used as a vegetable pesticide in pest prevention on rice plants, the most effective concentration used in this biological test is at 0.1% concentration, with very high effectiveness in eradicating pest on rice plants.
Historical and Legal Analysis of the Institution of Disposal of Property After the
Liquidation of Public Organizations
Authors: Bogolyubov Egor
Published: November 2020

Introduction. The history of public organizations is an actual topic of scientific research. Originated in
ancient times, they have passed a long way of development. Comparative study of the legal status of public
organizations is extremely rare, although such studies would be not only interesting, but also useful for further
improvement of legislation. Purpose. The aim of the study is to identify models of property disposal after the
liquidation of public organizations in Roman law and to trace the reception of these models at different stages
of development of domestic legislation. Methodology. Formal legal, comparative historical and comparative
legal research methods were used in writing the article. Results. It is revealed that in Roman law there were
three variants of disposal of property after liquidation of public organizations. In the domestic legislation these
models were applied in various configurations depending on concrete historical circumstances. The transfer of
property to state ownership was most often used in Soviet law, the direction of property for the implementation
of statutory purposes prevailed in pre-revolutionary legislation. Modern Russian law gives preference to the
latter option, but in rare cases allows the possibility of turning property into state property. Conclusion. The
issues covered in the article will allow to better understand the place and role of public organizations at
different historical stages of the development of the national state. The predominance of one or another option
of disposal of property after the liquidation of public organizations indicates the degree of freedom of the latter
from the state. A comprehensive study of the legal regime of the property of public organizations at different
stages of the development of civil society in Russia is seen as promising in this regard.

Authors: Tikhonov Sergey S.
Published: November 2020

Сonsiders issues related to the organization and conduct of ethno / ethnographic-archaeological works. The existing paradigm of studies of the phenomena of antiquity and the Middle Ages, based on the study of material sources, leads, as a result, to the study of various aspects of archaeological cultures. At the same time, the available opportunities for carrying out work on the study of demography, economics, ethnographic-archaeological “universals”, etc. are not fully used. In the author's opinion, in order to carry out full-scale operations such a plan, it is necessary to shift to changing the basis for conducting research.
