Published: March 2021

Background: Tumor drug resistance remains a primary cause of unsuccessful cancer therapy. The search for biological markers of the sensitivity/resistance of malignant neoplasms to drug therapy is an urgent and important task, the solution of which will increase the effectiveness of anticancer chemotherapy. Aim: To study the relationship between the functional activity (parameters of the phagocytosis and reactive oxygen species (ROS) production) of neutrophils and monocytes in the peripheral blood of rats with transplanted Guerin carcinoma and the degree of its sensitivity to cisplatin (Cpt). Materials and Methods: The original and Cpt-resistant variants of Guerin carcinoma were transplanted to female Wistar rats 2.5 months old. The parameters of the phagocytic activity of circulating neutrophils and monocytes were determined by the degree of ingestion of inactivated and FITC-labeled staphylococci using flow cytometry. The number of ROS-generating cells and the intensity of ROS production by phagocytes were determined by flow cytometry using 2’,7’-dichlorodihydrofluorescein diacetate. Results: The growth of both variants of Guerin carcinoma caused a statistically significant decrease in the intensity of neutrophil phagocytosis by more than 47% with a tendency to the reduction of the intensity of phagocytosis by monocytes. The phagocytic activity of circulating neutrophils and monocytes did not differ significantly between the groups of animals with the original and Cpt-resistant variant of Guerin carcinoma. In contrast, the intensity of ROS generation by both monocytes and neutrophils in the peripheral blood of animals with Cpt-resistant tumor increased by more than 86% as compared to original carcinoma-bearing rats. Conclusion: This study provides evidence that the intensity of ROS production by circulating monocytes and neutrophils may reflect the degree of tumor sensitivity to Cpt. Increased intensity of ROS production could serve as a pretreatment predictor of the formation of tumor drug resistance.

Summary. Prostate cancer (PCa), the most common solid malignant neoplasm in men, is characterized using the Gleason score and diagnosed using prostate-specific antigen (PSA) biomarker. However, Gleason score and PSA-based diagnostics are not universal and have significant limitations. It is supposed that the ornithine decarboxylase activity (AODC) could be a suitable auxiliary biomarker for the PCa diagnosis or monitoring the therapeutic efficacy. Aim: To assess the relation between AODC in PCa tissues and the level of serum PSA with the Gleason score (GS) and the clinical stage. Materials and Methods: 29 patients (48 to 79 years old) with prostate adenocarcinoma of different GS (6 to 10) and clinical stage (T1 to T4) were enrolled in the study. The AODC was analyzed in the PCa tissues by the modified spectrophotometric assay. Results: The patients with PCa were distributed into two groups: with low AODC < 0.3 and high AODC > 0.45. In group with AODC < 0.3, the highest value of AODC was recorded in patients with the lowest GS (= 6), while in group with AODC > 0.45, the highest value of AODC was recorded in the patients with the highest GS (= 9–10). Furthermore, in group with AODC > 0.45, the highest value of AODC was registered in the patients with T1 or T4 stage. The highest levels of serum PSA were detected in T3–T4 cases and in cases with the highest GS. Conclusion: The patterns of AODC and serum PSA can be used as supplementary indices useful for monitoring PCa course.

Published: March 2021

This work presents a mathematical algorithm for modeling the propagation of poroelastic waves. We have shown how the classical Biot equations can be put into Ursin’s form in a plane-layered 3D porous medium. Using this form, we have derived explicit for- mulas that can be used as the basis of an efficient computational algorithm. To validate the algorithm, numerical simulations were performed using both the poroelastic and equivalent elastic models. The results obtained confirmed the proposed algorithm’s reliability, identify- ing the main wave events in both low-frequency and high-frequency regimes in the reservoir and laboratory scales, respectively. We have also illustrated the influence of some physical parameters on the attenuation and dispersion of the slow wave.

Authors:   Bukhara Branch of the Institute of Mathematics at the Academy of Sciences of the Republic of Uzbekistan, Bukhara, Uzbekistan, Durdiev D. K.
Published: March 2021

We study the inverse problem of determining the time depending reaction diffu- sion coefficient in the Cauchy problem for the time-fractional diffusion equation by a single observation at the point x = 0 of the diffusion process. To represent the solution of the direct problem, the fundamental solution of the time-fractional diffusion equation is used and properties of this solution are investigated. The fundamental solution contains the Fox’s H− functions widely used in fractional calculus. In particular, using estimates of the fundamental solution and its derivatives, an estimate for the solution of the direct problem is obtained in terms of the norm of the unknown coefficient which will be used in study inverse problem. The inverse problem is reduced to the equivalent integral equation. For solving this equation the contracted mapping principle is applied. The local existence and global uniqueness results are proven. Also the stability estimate is obtained.

The paper studies the problem of determining the boundary condition in the heat conduction equation for a rod consisting of homogeneous parts with different thermophys- ical properties. We consider the Dirichlet condition at the left end of the rod (at x = 0) corresponding to the heating of this end and the homogeneous condition of the first kind at the right end (at x = 1) corresponding to cooling during interaction with the environment as boundary conditions. At the point of discontinuity of the thermophysical properties (at x = x0), the conditions for the continuity of temperature and heat flux are set. In the inverse problem, the boundary condition at the left end is assumed to be unknown. To find it, the value of the direct problem solution at the point x0, i.e., the point of separation of the rod into two homogeneous sections, is set. In this work, we carried out an analytical study of the direct problem, which allowed us to apply the time Fourier transform to the inverse boundary value problem. The projection-regularization method is used to solve the inverse boundary value problem for the heat equation and obtain error estimates of this solution correct to the order.

Tamora Catfish Company as a Micro, Small and Medium Enterprise (UMKM) which one of the Universitas Sumatera Utara community service partners, used a simple microbubble technology system to increase the dissolved oxygen content in pond water in order to anticipate of the large number of die fish because of the polluted pond water, which impacted in reducing the amount of oxygen. Biofloc application was observed decreasing the ammonia content and generating natural feed. This was analyze by the team that already implemented this simple technology in the first year observation which found its successfully reduce fish mortality and increase the number of catfish. However, the catfish food is expensive because it is depend on pellet feed, so the production process costs are very high. Via a multi-year system, community service team utilizes conventional market waste as a feed in order to replace the use of costly pellet feed. The solution was starting from processing conventional market waste such as vegetables waste. It was considered because it is cheap and it needs simple machine technology to produce the feed. The machine will construct by copper and mixer in order to produce feed that suitable for catfish food. Furthermore, it also impacted to make conventional market cleaner from waste since partners collect and process the waste directly.

Malaria is a mosquito-borne infectious disease of humans and other animals caused by parasitic protozoans (a type of unicellular microorganism) of the genus Plasmodium. Commonly, the disease is transmitted via a bite from an infected female Anopheles mosquito, which introduces the organisms from its saliva into a person’s circulatory system. In the blood, the protists travel to the liver to mature and reproduce. Malaria causes symptoms that typically include fever and headache which in severe cases can progress to coma or death. The disease is widespread in tropical and subtropical regions in a broadband around the equator, including much of Sub-Saharan Africa, Asia, and the Americans Five species of Plasmodium can infect and be transmitted by humans. The vast majority of deaths are caused by Plasmodium falciparum and Plasmodium vivax, while Plasmodium ovale and Plasmodium malariae cause a generally milder form of malaria that is rarely fatal. The result showed that prevalence of typhoid fever in both male and female are 9 (%) and 21 (21%) respectively. The distribution of this result was statistically significant (p<0.05; X2=4.745). The result showed that prevalence of typhoid fever in both male and female are 6 (6%) and 4 (4%) respectively. The distribution of this result was not statistically significant (p>0.05; X2=0.105). The result showed that prevalence of the co-infection in both male and female are 3 (3%) and 2 (2%) respectively. The distribution of this result was not statistically significant (p>0.05; X2=0.205). The result showed that co-infection was negatively correlated with typhoid fever in both male (r=-0.055) and female (r=-0.074) subjects. Also co infection was negatively correlated with malaria for male subjects (r=-0.044) while it is positively correlated with the female subjects (r=0.335). Similarly typhoid fever was negatively correlated with malaria in both male (r=-0.079) and females (r=-0.105) subjects. Conclusively, the results in this study showed that the prevalence of malaria and typhoid co-infections are low which means the no association was found between malaria and typhoid fever infections within the study area. Hence one cannot actually say that malaria may predispose to typhoid fever. Also cross reacting antigens are widely distributed in the microbial world and since there will always be repeated exposures to salmonella species in endemic regions, increased efforts should be made to find a better, more rapid, sensitive and specific clinical and cultural methods.
Effects of Intra-Row Spacing on Yield and Yield Components of Sugarcane (Saccharum spp. hybrid) Varieties at Omo Kuraz, Southern Ethiopia
Authors: Alehegn Wubante , Girma Amare , Khan A. Q.
Published: March 2021

Sugarcane stalk population is a key determinant of cane yield and knowing the right intra-row spacing is a critical factor in sugarcane production for a given environment. Therefore, a field experiment was conducted at Omo Kuraz Sugar Estate during the 2018/ 2019 cropping season to determine the effect of intra-row spacings (5 cm overlapping, end-to-end, 5 cm spacing between setts and 10 cm spacing between setts) on growth, yield, yield components and quality parameters of sugarcane varieties (N14, Mex54/245 and C86/112). The treatments were arranged in a split-plot design with three replications. Varieties were represented as the main plot whereas setts spacing treatments were assigned to sub-plots. Analysis of variance revealed that the intra-row spacing effect didn’t show a significant difference in the number of tillers, plant population, millable cane, cane yield, sugar yield, and Brix percent whereas significant (P<0.05) differences were observed in stalk height, stalk girth, number of internodes and weight per stalk. Therefore, the 10 cm intra-row spacing of three budded setts can be recommended for better productivity and profitability of N14 and Mex54/245 varieties at the Omo Kuraz Sugar factory.

Published: March 2021

A substantial amount of literature has revealed gender gaps in political participation. However, little is known about such gaps when using more comprehensive measures of civic and political participation including online participation. In the present study, we recruited a sample (n = 1792) of young people living in Italy. Controlling for age, majority/minority status, socioeconomic status, respondents’ educational attainment, and parents’ educational attainment, we found that female participants reported higher scores on online and civic participation, while male participants were more likely to report political and activist participation. The effect size for these gender differences was small. In addition, we did not find any gender differences in voting behavior in the last European parliamentary elections, national parliamentary elections, and local elections. These findings highlight the need to move toward a more comprehensive and detailed picture of gender gaps in political engagement and participation including different types of participation.

Published: March 2021

No contexto da pandemia do COVID19, com graves consequências para vida, a saúde pública, o trabalho e rumos da economia, questões relevantes emergem para o diálogo entre Educação e Geografia. Por exemplo, diante da necessidade de distanciamento físico e fechamento das escolas, propaga-se o ensino remoto, usando tecnologias digitais como substituição às aulas presenciais e deslocando da escola para a casa o espaço de docência-discência. Aqui examinamos como conceitos geográficos, a exemplo de espaço, território, territorialidades, des(re)territorializações (MASSEY, HAESBAERT), em interlocução com o pensamento de Paulo Freire sobre dialogicidade e dimensão relacional da Educação, podem contribuir para o estudo de tensões, dimensões políticas, pedagógicas e sociais dessa problemática.

Immigrant Integration and COVID-19
Authors: Rebhun Uzi
Published: March 2021

Covid-19 has thrust millions of people who have recently crossed international borders into unprecedented social and economic havoc. The patterns of immigration and settlement in a new country, on the one hand, and the nature of the virus, on the other hand, have placed immigrants at high risk of infection, possibly generating or accelerating anti-immigration sentiments among the local population. In this viewpoint, I discuss five complementary aspects of the migration-pandemic nexus: immigrants’ legal status, language proficiency, ethnic segregation, religiosity, and economic wellbeing. My concluding remarks carry several implications for policy.
‘Are We An Experiment?’ Informality as Indispensable for Syrians’ Resettlement in the UK
Authors: Blunt Caroline
Published: March 2021

This article unpacks the status and significance of informal social infrastructures within the Syrian Vulnerable Person’s Resettlement Scheme (SVPRS) in one region of the UK to offer a case study exemplifying an enduring and renewed political embeddedness of informalities as an idiosyncratically British way of governing migrant incorporation and producing social order. From the perspective of the scheme’s formal design, this was ‘bottom-up’, ‘community-led’ activity for community or ‘social’ integration. For refugees this was the existence and availability of a quality of sociality productive of a sense of existence and a viable and possible life, in other words, defining – above and beyond discrete domains or material things - what had been hoped for and expected from resettlement. Where this ‘informal social infrastructure’ was available, refugees conveyed an experience of positive processes of life, resonating with discussions of existential movement. Where unavailable refugees conveyed experience of a persistent or even worsened sense of biographical interruption that forced migration has been likened to. The article aims to contribute to informalities scholarship in relation to the imbrication of informal-formal as means of governance and attest to the significance of informalities to the reduction of uncertainty, production of stability.

Introduction: Ackerman’s tumor or Verrucous carcinoma is a distinguished clinic-pathological variant of squamous cell carcinoma, presenting with multiple clinical presentations. This study provides a contemporary survey of morphological presentation of oral verrucous carcinoma (OVC) in the oral cavity with site of predilection and possible etiological factors.

Method: An observational studywas conducted from January 2014 to June 2016.A suspected patient diagnosed clinically and histologically as OVC at the Dhaka Dental College Hospital (DDCH) was enrolled in this study. Results: In this study total 15 number of patients male were 53.3% and female were 47%. The morphological presentation of the study was proliferative and verrucous, each of which comprises 40.0% of cases. The tumor's primary site was the buccal mucosa 46.67% and history ofbetel quid chewing was 46.9%.

Conclusion: The study concluded that it is very difficult to distinguishing clinically between verrucous carcinoma and other exophytic lesions of the oral cavity. OVC presents with different morphological presentation such as proliferative and verrucous types. Buccal mucosa is the site of predilection.

Goal-Setting Model in Multilevel State Strategic Management of Socio-Economic Development
Authors: Pisareva Olga M.
Published: March 2021

In the context of the deployment of transient processes and the exacerbation of crisis phenomena in socio-economic systems of various types, the importance of a reasonable setting and correction of development goals increases. For the current situation in the Russian Federation, when the implemented program of constitutional amendments creates the preconditions for the subsequent reform of public authorities and the mechanism of multi-level strategic planning, it is especially important to conduct research in the field of substantiating scientific approaches to the development of mathematical methods for solving the problem of strategic goal-setting. One of the key points in the modernization of the methodological support of strategic planning in the context of the constitutional transformation of the system of public authorities is consideration of the value foundations of activities in the systems of distributed management of socio-economic development, analysis of the problems of formalizing the setting of goals by the participants in the multi-level strategic planning process and substantiation of the structure of the theoretical model of goal-setting. The article considers the general characteristics of the functioning of the system of state strategic planning in the Russian Federation from the point of view of goal achievement. The institutional and conceptual foundations of goal setting are presented. The relationship between the concepts of “goal”, “target indicator” and “target function” are shown. The interrelation of the tasks of goal-setting and programming of the activity of an economic agent is characterized. An approach to formalizing goal-setting based on a theoretical scheme of mutual development planning tasks is proposed. The general structure of the strategic goal-setting model in the organizational mechanism of multi-level long-term planning determined. A possible approach to the algorithmization of the solution of the linear formulation of the goal-setting problem in the multisubject development control space based on the methods of target programming and multicriteria optimization was proposed. The formation of an operator of iterative management of the potentials and development priorities of interacting economic and social agents on the horizon of strategizing substantiated. To introduce a theoretical model of goal-setting into the practice of strategizing in the context of the formation of a digital platform of public administration, it is necessary to develop appropriate algorithmic support, as well as the formation of a regulatory and information base and the definition of an organizational and technological basis. Further improvement of the analytical and methodological tools for supporting the activities of strategic planning participants at the goal-setting stage is associated with the description and analysis of the corresponding applied tasks of goal setting at various levels and areas of socio-economic development planning.
Development of the Risk Accumulation Method for Calculating the Capitalization Rate
Authors: Trifonov Nikolai Yu.
Published: March 2021

Risk build-up method is the most used for calculating the capitalization rates. With the help of the literature analysis, the origin of this method is considered. The method was based on the relationship between risk and profitability of a stock in exchange trading, proven statistically. Later, when formulating the build-up method, this idea was transferred without any justification to the valuation of enterprises that do not list their securities on stock exchange. In other words, the formulas traditionally used in the application of the build-up method are empirical in nature and not precise.It is more accurate to write them down by analogy with Irwin Fisher's equation of returns. Based on the principle of dependence, one of the main ones for the valuation procedure, the essence of which is that the value of the valuation subject depends on its economic location, a set of four independent risks is given for use in the build-up method in general case: risk-free rate, country risk premium, branch risk premium, and subject risk adjustment. It is noted that the numerical value of these parameters used in the method fundamentally depends on the monetary unit used in the calculation (the valuation currency). Recommendations are given on finding a risk-free rate for various currencies, on calculating country risk premium, branch risk premium, and subject risk adjustment. The article is intended for academics, lecturers, and practitioners in such areas as corporate finance, business microeconomics, valuation, and investment analysis.

Published: March 2021

The preservation of a large and complex museum vessel is often demanding work in building good practices and beneficial networks among specialists, supporters, and the community. The grain elevator “Stadsgraanzuiger 19” that can be visited either at Maritime Museum Rotterdam or Museum aan de Stroom in Antwerp is a case in point. It’s story exemplifies that challenges in museum collections and research work to permanently preserve such a spectacular and massive machine. In this article Richard Velthuizen revisits the history of grain elevators, the socio-technical change at Rotterdam port, and the preservation and cultural heritage efforts in saving this historic elevator. He also unentangles the social process with which the large, floating machine has been preserved.

Pada studi analisa ekonomi digunakan untuk mengetahui kelayakan pembangunan Biodigester dalam menentukan rincian anggaran biaya dan didapatkan harga Rencana anggaran biaya senilai Rp. 2.301.000,- dan investasi dalam jangka 5 tahun ke depan dengan parameter Net Present Value (NPV)= Rp 7.512.000,- (bernilai positif), Probality Indeks (PI)= 3,2 ≥ 1 dalam jangka investasi,  Internal  Rate Of Return (IRR)  pada suku bunga yang berlaku secara umum NPV bernilai positif dan tidak ditemukan IRR dan Payback Periode (PP) = 1,3 Tahun (≤ jangka investasi 5 tahun) usaha kembali modal. Analisa kelayakan lingkungan didapatkan hasil bahwa outer biodigester aman dan bau sedikit menyengat serta berkurangnya limbah cair pabrik tahu, penanganan dari outer tersebut adalah di jalur khusus ke drainase tertutup atau pipa ke tempat pembuangan akhir atau tangki septik tertutup. ABSTRACTThe impact of the tofu processing industry is their liquid waste which mostly causes problems. Tofu liquid waste can be used as biogas. For that, we need a feasibility study for the development of a Biodigester from a technical, economic, and environmental perspective. The process of technical analysis is used to determine the type of digester and the suitable and efficient place, obtained from operational costs, land area, and production capacity. From the technical analysis study, the selected type of reactor installation was obtained, namely the modified Cover Lagoon Anaerobic Reactor (Colar) with a portable model with a capacity of 200 liters. The economic analysis study is used to determine the feasibility of the Biodigester development in determining the detail of cost budget and it reached Rp. 2.301.000.00, - and the investment in the next 5 years with the parameter Net Present Value (NPV) = Rp. 7.512.000.00 (positive value), the probability Index (PI) = 3.2 ≥ 1 in the investment term, the internal Rate Of Return (IRR) is generally positive at the applicable interest rate, and there is no IRR and Payback Period (PP) = 1.3 years (≤ 5 years investment) of the return on investment. The environmental analysis study resulted that the outer biodigester is safe and smells a bit sting to reduce the liquid waste from the tofu factory. Those handling of the outer is located in a special route pipe to the final landfills site or closed septic tank.
