Окислительный стресс, вызванный ишемически-реперфузионным поражением почек, может играть ключевую роль в дисфункции печени. Для снижения поражения печени и почек при ренальном ишемически-реперфузионном поражении в работе использовали экзогенный фермент-антиоксидант пероксиредоксин 6, который способен восстанавливать широкий спектр гидропероксидов и является участником во внутриклеточной и межклеточной передаче сигналов. Крыс подвергали ишемическому поражению почек в течение 45 мин с одновременной левосторонней нефроэктомией и обследовали через 24 и 48 ч реперфузии. Пероксиредоксин 6 вводили внутривенно за 15 мин до ишемии. Повреждение почечной и печеночной тканей определяли гистологическими методами, для оценки функциональности органов измеряли концентрации креатинина, мочевины, аланинаминотрансферазы и аспартатаминотрасферазы в крови. Реперфузия привела к увеличению концентраций креатинина, мочевины, аланинаминотрансферазы и аспартатаминотрасферазы в плазме; нарушению архитектуры почечных нефронов и развитию выраженной сосудистой реакции в печени с очагами дегенеративных изменений. Использование экзогенного пероксиредоксина 6 привело к снижению поражения ренальной и печеночной тканей и нормализации уровня почечных и печеночных метаболитов. Таким образом, пероксиредоксин 6 проявляет как нефро-протекторный эффект при ренальной ишемии-реперфузии, так и уменьшает морфофункциональное повреждение отдаленных органов, в частности печени.

Published: August 2021

Світова тенденція переходу людства до сталого розвитку дуже залежить від безперебійного постачання різних мінералів або матеріалів. У цьому контексті надзвичайно важливим є налагодження співпраці між різними зацікавленими сторонами в керуванні критично важливими матеріалами на всьому глобальному ланцюжку постачання.У статті наведено стислий огляд появи поняття “критична сировина” та траєкторій розвитку національних стратегій щодо критично важливих мінералів в основних зацікавлених регіонах – Китаї, США, Європі, Японії та Австралії. Забезпечення надійного й неупередженого доступу до корисних копалин стає дедалі важливішим чинником конкурентоспроможності, тому країни-імпортери скоординованими діями стимулюють диверсифікацію, тобто збирають дані про виробництво, переробку мінеральних ресурсів і торгівлю ними. Україна, у надрах якої зосереджено широкий спектр корисних копалин, у перспективі може стати одним з надійних партнерів для споживачів критичної мінеральної сировини, зокрема Європейського Союзу.

Determination of the hydrophone phase-frequency response by its amplitude-frequency response
Authors: Isaev Alexander E. , Khatamtaev Bulat I.
Published: August 2021

One of the tasks of the COOMET 786/RU/19 pilot comparisons is to check the correctness of the hydrophone model proposed in VNIIFTRI, consisting of an advance line and a minimum-phase part, including the effect of sound diffraction and resonance properties of the active element. This model makes it possible to use the Hilbert transform to obtain the phase-frequency response from the amplitude-frequency response as well as for inverse operation. The results of measuring experiments performed using facilities of the State Primary Standard GET 55-2017 are presented. For many practical tasks, it is not necessary to obtain the phase-frequency response for an acoustic center of the receiver. It is enough to determine the shape of the phase-frequency response using much less laborious methods. The question of which of the characteristics is expedient to determine during calibration - for an acoustic center, or for a point on the surface of an active element, deserves a discussion among specialists performing acoustic measurements.

Published: August 2021

The KRPL (Sustainable Reserve Food Garden) program is an alternative in realizing food self-sufficiency to achieve food security during the Covid-19 pandemic. This study is to determine the impact of the KRPL program on household food expenditure patterns, food consumption patterns, and consumption levels by using a questionnaire interview method in 8 active KRPL groups in the city of Kediri with a total of 80 respondents. The result of this study indicates that as much as 70% of the harvest in process for the food and nutritional needs of the family, 38.75% think that the yields from their yards can meet their food needs. The yields of each KRPL are different due to several factors, namely, the area of land, the awareness of group members, the weather, and the desire of the members to plant types of plants. From the amount of harvest, it can be seen that the level of success of the KRPL program has a positive impact on household food consumption patterns. A yard or harvest yields are still dominant for household consumption. This condition supports the main concept of the KRPL program, namely to strengthen household food security.

Background: Age-related macular degeneration (AMD) is the leading cause of vision loss in the elderly. Although it has been shown that Y402H polymorphism in the CFH gene was strongly associated with AMD in the Iranian population, there were no data on other single nucleotide polymorphisms (SNPs), which have the most significant association with AMD. This study aimed to investigate hot point regions in exon 10 and intron 9. Materials and Methods: One hundred and sixty-six AMD patients and 69 controls were recruited. Their blood was collected in the tubes containing EDTA. Then, DNA was extracted from the blood, and its quality was evaluated. Primers were designed for intron 9 and exon10 sequencing. A viral polymorphisms analysis software named CEQ was used for the analysis of putative polymorphisms. Results: We noticed three polymorphisms in study cases: rs7535263 and C66379A in intron 9 and rs2274700 in exon 10. Based on the McNamara’s test (rs7535263 and rs2274700) and the Phi and Cramer’s test (C66379A), a significant difference was found between the control and patient groups regarding rs7535263 and rs2274700 polymorphisms. Conclusion: We found a synonymous or silent mutation, A473A, rs2274700 in exon 10 in 85% of patients. From two intronic SNPs, just rs7535263 showed association with the disease in studied patients living in Gilan Province, Iran. Although no significant relationship was found between controls and patients regarding the C66379A allele, it would be important that no other sources have reported C66379A polymorphism in AMD yet.

Seeking efficient management for the judiciary: An agenda under construction?
Authors:   Universidade do Sul de Santa Catarina, Brasil, Salazar Clarissa
Published: August 2021

The purpose of this theoretical essay is to reflect on the current discussion about the management of the Judiciary. We are currently living in a moment of rupture, in a scenario of disproportion between the offer of services and the number of conflicts to be resolved. Co-production has been advocated as an alternative through the participation of users of these services in decision-making. For this discussion, we bring in the New Public Management that proposes reforms based on the same logic of action that governs private companies. And the New Public Service, which defends productivity and efficiency in a larger context of democracy and public interest. We conclude that there is no dichotomous thought in the construction of a management model that is coherent with the difficulties and the complexity of the provision of justice. But there is a rupture with the conservative past, the search for a new identity, without losing its legitimacy and commitment to democratic principles.

Institutional Clashes Beyond the Judicialization of Health: Overlapping Powers in the Case of the Cancer Pill
Authors:   Pontifícia Universidade Católica do Paraná, (PUCPR), Brazil, Godri Luciana , Marcelino Carolina ,   Tribunal de Contas do Estado do Paraná (TCE-PR), Brazil
Published: August 2021

The 1988 Brazilian Federal Constitution institutes the promotion of “universal and equal access” to health care for Brazilian citizens. In this article, we will focus on the use and distribution of medicines as one of the national health system components. The organization responsible for standardizing and regulating the production and consumption of products and services is ANVISA – National Health Surveillance Agency, which works like the FDA (Federal Drug Administration). A unique episode took place in 2015 when a “popular uprising” began to take shape in Brazil around an issue regulated by ANVISA. Cancer patients had started to file lawsuits calling for access and permission to use a drug not authorized by this agency and which, according to the askers, supposedly would cure their disease. This drug is named phosphoethanolamine (popular name, cancer pill). Apart from the efficacy or otherwise of the drug in question, it might be interesting to organizational studies why a government organization may miss legitimation to exercise its legal role due to popular pressure, which strongly diverges from court decisions, especially involving power and legal interpretation. We approach theoretical possibilities about judicialization of health discussing triggers of institutional and social conflicts (a) by surveying studies that deal with judicialization calling for supply or release of medication (b) possible connections already established in the academy with the so-called cancer pill and, finally, (c) relating such situations to the concept of institutional void.

Published: August 2021

This article intends to analyze the decision-making stages of the judicialization of public health policy in Brazil by the highest legal court in the country — the Supreme Federal Court of Justice (STF). Subsequently, we present the most relevant criticisms of the excessive judicialization of health, attempting, to list alternatives in order to discuss a possible program of improvements for public health policy, having as its main element the dialogue between the Brazilian Justice and Health Systems. The methodology used can be characterized as quali-quantitative, considering that data collection was used on the STF website for research and analysis of judicial decisions, as well as a biographically doctrinaire review.

Purpose. To substantiate a rational schedule for the combined dragline-truck operation taking into consideration a coefficient of mining in the context of the pit. Methodology. Mathematical and graphical modeling was involved while determining a coefficient of mining concentration in the pit as well as feasibility analysis to select a rational procedure scheme for dragline operation. Findings. Recommendations for the selection of rational dragline operation, while truck loading in the context of Motronivsko-Annivskyi pit, have been developed taking into consideration mining concentration degree in the pit. It has been determined that bottom dragline unloading into a truck, located in the central part of bench mining width, as well as the dragline position at 0.5 A distance from the bench crest, is the most efficient plan of action for the conditions. Technological scheme to develop Motronivsko-Annivskyi pit has been proposed. Originality. Dependence of the mining concentration in the pit upon the parameters of development system elements according to different technological schemes has been derived. The dependence helps estimate development cost for overburden rocks using draglines with direct unloading into trucks. Practical value. Technological schemes for the combined dragline dump truck operation have been developed. Their use makes it possible to cut the prime cost of overburden activities. Implementation of the proposed solutions helps cut stripping cost by UAH 79.65 million a year if annual overburden volume is Qrozkryvu - Qstripping = 13.5 million m3/year.

Published: August 2021

Purpose. Increasing the jet mill productivity by use of automatic control of the grinding chamber filling level based on the acoustic monitoring results of the jet grinding process. Methodology. Simulation is performed in MATLAB. Acoustic signals of the mill operating zones are used to determine the grinding process parameters. Findings. A simulation model of the automatic jet mill control system is created, which takes into account the inertia of material flows in the grinding chamber and classifier, as well as the main disturbing influences on the process of forming the mill output flow. To analyze the control process, there are three main parts the information component (regulator and technical means of automation), a set of mathematical models that describe the physical processes in the grinding chamber and in the classifier. A study on the automatic control process of the grinding chamber filling is made under the condition of determining the controlled value indirectly through spectral analysis of the acoustic signal in the mill. The insignificant influence of perturbations on the controlled quantity due to very slow filling of the chamber with material in comparison with the period of stream fluctuations at a chamber entrance owing to perturbation action is shown. Originality. For the first time the possibility has been proved of using a relay regulator in control of the grinding chamber filling, determined indirectly through spectral analysis of the acoustic signal in a jet mill. The efficiency of the mill operation at automatic control of the grinding chamber filling according to the relay law is investigated. Practical value. It is shown that with the transition from automated to automatic control of the grinding chamber filling, the mill productivity increases by 1015%. The obtained results are used to build a system of automatic jet mill control.

Purpose. In order to fully exploit the metal and facilitate its method of processing, we need an accurate knowledge of its composition, granular distribution, and association with unimportant and penalizing elements that we would like to get rid of, compared to the distribution of the element to extract by flotation method. Methodology. The present experimental work proposes an approach to the mineralogical, chemical and particle size characterization, several analyzes have been carried out by Scanning Electron Microscopy with Energy Dispersive Spectroscopy (SEM/EDS), X-ray Diffraction (XRD), Optical Microscopy (OM), Particle Size-Fraction Analysis (PSFA), and X-ray Fluorescence (XRF). These analyzes were submitted on samples of lead-zinc of different sizes as well as well-prepared fine powder of this ore; the zinc content of the raw material is about 5% Zn. Findings. The results obtained by the mineralogical characterization and the particle size analysis reveal a very varied and irregular texture of the ore, consisting mainly of sulphides (sphalerite, galena, pyrite, marcasite), associated with carbonate gangue, mainly dolomite and calcite. The theoretical dimensions of the particles found in the fine grain size classes [-1 +0.053] mm.

Due to the continuous development of the building-and-construction industry, it is necessary to design new or modify outmoded industrial equipment. Using jaw crushers with the impact action of crushing plates on material is a perspective line of developing crushing equipment. Purpose. Developing a mathematical model of a vibratory jaw crusher and studying the operational process which is based on the mathematical model in order to design new crushers. Methodology. Definition of the crusher working process is based on the main statements of the theory of mechanical oscillations and the theory of continuous environment. In the motion equations of the crusher the material is taken into account on the basis of a discrete model by a continual parameter. Findings. A physical model is developed on the basis of which motion equations are derived, which include three main conditions of the efficient operation: 1) the elasticity of the second vibrating element must exceed or be equal to crushing force; 2) vibrations of the first and the third vibrating elements must be in phase, and vibrations of the second vibrating element must be in antiphase; 3) the summarized displacement of the second and the third crushing plates must ensure crushing of material. Graphs of the effect of the vibrating elements and elasticity coefficients of elastic systems on the amplitudes of vibrations are plotted and analyzed. On the basis of the motion equations, with consideration for the optimal parameters of the crusher vibrating elements and for the elasticity coefficients of the elastic systems, the amplitude-frequency characteristics of the crusher for different frequency ranges are determined. Set up is an equation describing the displacement of material in the crushing chamber for a time interval required for the crushing plates to be separated. Presented are graphs of dependency of the amplitude of vertical vibrations of the crusher casing on the elasticity of the isolating elastic system, and provided are recommendations for selecting and calculating vibration isolation. Originality. A mathematical model of an experimental vibratory jaw crusher and the characteristics of the experimental crusher are presented, on the basis of which recommendations are given for the selection of energy-efficient operating modes of the crusher. Practical value. Knowledge on the rational values of the frequency ranges for operation of the studied vibratory jaw crusher makes it possible to determine the optimal level of power consumed by the crusher and efficiency in processing materials of different hardness.

Purpose. This research investigates the separation process performed by a magnetic separator. The magnetic separation process is used to isolate ferrous materials from those which are not. Hence, a prototype of a dry magnetic separator is designed. It should be said that this study defines the effect of different parameters (roll speed, magnetic force, and mass of silica sand particle) on separation efficiency. Methodology. The influence of several parameters of the magnetic separator such as magnetic force, centrifugal force, and properties of particle (mass, shape, etc.) were studied theoretically and simulated by SolidWorks software. The optimum conditions of the magnetic separator were obtained, and several trials were performed to find the point that results in a lower effect of roller speed and a higher effect of the magnetic force on the particle in order to achieve higher separating efficiency. Findings. The results show that the centrifugal force are the most important variable influencing separating efficiency. Moreover, it was found that blade angle magnitude of (174) degree with magnetic force between (1.71E-05 to 6.3E-05 N) and roll speed from (84 to 105 rpm) are the optimum separating conditions to reach higher rate of the separating process. Originality. This is the first time that the effect of the gap distance between the magnet and the feeding particles on the magnetic force has been studied. Furthermore, the effect of centrifugal force on magnetic separator force is investigated theoretically and numerically in order to be compared for different parameters. Practical value. The new prototype design of the magnetic separating unit is promising and efficient since the parameters can be varied based on the type and characteristics of materials. It is also revealed that separating time of the materials is reduced. Hence, this type of construction of a magnetic separator is recommended for industrial applications.

longitudinal dynamic stresses and investigate the peculiarities of the propagation of dynamic stresses along the route of material transportation. Methodology. To calculate the value of static and dynamic stresses arising in the conveyor belt, the apparatus of mathematical physics was used. Findings. A wave equation is written that determines the propagation of longitudinal vibrations in a conveyor belt, the material of which corresponds to the Maxwell-element model. An expression is obtained for calculating the speed of propagation of elastic vibrations along the conveyor belt, the frequency of vibrations and their wavelength. The characteristic relaxation time of disturbances is determined. The method of successive approximation was used to solve the wave equation. The estimation of the characteristic time of acceleration of the conveyor belt, at which there is no destruction of the material of the conveyor belt, is given. Originality. PDE-models of conveyor-type transport systems are improved, which are used to design belt speed control systems under restrictions on speed control modes. It is shown that under the modes of acceleration or deceleration of the conveyor belt, the effects associated with the occurrence and propagation of dynamic stresses along the conveyor belt, due to the characteristics of the material corresponding to the Maxwell-element model, are insignificant. Practical value. The results obtained make it possible to determine the limitations on the modes of acceleration or deceleration of the conveyor belt, preventing its damage and increased wear. This opens up prospects for designing effective control systems for the parameters of a conveyor belt, unevenly loaded with material along the transport route.

Purpose. This research aims to promote the assay of iron and reduce the phosphorus grade of the final DRI. Methodology. A high-phosphorus oolitic iron ore from Gara Djebilet deposit underwent the procedure of coal-based direct reduction (coal-based DR) followed by wet low-intensity magnetic separation (WLIMS). The effects of temperature, periods of time and Na2SO4 dosage on phosphorus removal, metallisation degree and iron recovery rate were tried and optimised. Furthermore, phase changes in iron oxides and the distributing features of phosphorus in both reduced and magnetic materials were investigated as well. Findings. The appropriate addition of sodium sulfate improves the Fe-P separation during the coal-based DR of Gara Djebilet mixed pellets. Originality. Using additives of CaO and sodium sulfate during the coal-based DR-magnetic separation of mixed pellets sourced from Gara Djebilet deposit. Practical value. The results reveal that a final direct reduced powder (DRI) assaying 96 wt% Fe and 0.16 wt% P at a recovery rate of 97.72% was obtained when the ore-coal-CaO mixed pellets were reduced in the presence of 5 wt% Na2SO4 at 1250 C for 30 min. Thus, the coal-based DR could be used as an alternative to the blast furnace (BF) route in the steelmaking industry from refractory iron ores.

Purpose. To conduct a systematic analysis of the state environmental policy, to identify threats to ecologization and the necessary directions for improvement of the state environmental policy. Methodology. To perform scientific research there were used: the method of content analysis to assess the scientific achievements and identify unresolved aspects of the problem; method of comparative analysis for evaluation and processing of statistical information; method of analysis and synthesis to form the purpose of the study; methods of abstraction and generalization, formalization for detailed elaboration of various aspects of the problem; system-structural method and the method of convergence from the abstract to the concrete for the formation of conclusions and proposals. Findings. New risks and threats to the state environmental policy have been identified and their impact has been analyzed. The analysis revealed that the state environmental policy does not always extend into regional and sectoral environmental policy. It is established that departmental structures responsible for environmental monitoring do not have proper coordination of their actions, even in time, which complicates integrated information processing. In many areas there is no long-term state forecasting of environmental and economic factors. There is no adequate level of systematization in the formation of structured economic and tax incentives for the introduction of effective environmental technologies and compliance with norms and rules in environmental protection. Originality. A systematic analysis of the state environmental policy has been carried out, the formation of the emergent nature of ecological and economic factors has been indicated. Mechanisms of the state ecological policy have been formulated. Threats for ecologization policy and necessary directions of improvement of the state ecological policy have been detected. Practical value. The results of statistical analysis can be used by scientists and practitioners. To reform environmental and economic policy, the threat of imbalance in economic and tax incentives for greening has been pointed out, which may lead to delays in the development and slowdown of technological renewal of industrial sectors, in particular, the energy sector. It has been pointed out that the state ecological and economic policy should be a systemic tool of social policy, help stabilize the situation and overcome the crisis in all spheres of life. The importance of the role of the civil sector in the ecologization of the country and of the need to form a system for developing the environmental consciousness of society has been indicated.
