Authors: Boujounoui K. , Abidi A. , Baçaoui A. , El Amari K. , Yaacoubi A.
Published: August 2021

SYNOPSIS Response surface methodology (RSM), central composite design (CCD), and desirability functions were used for modelling and optimization of the operating factors in chlorite and talc (collectively termed 'mica') flotation. The influence of pulp pH, cyanide (NaCN) consumption, and particle size was studied with the aim of optimizing ssilicate flotation while minimizing recoveries of galena, chalcopyrite, and sphalerite. Flotation tests were carried out on a representative sample of a complex sulphide ore from Draa Sfar mine (Morocco). The model predictions for the flotation of each of the minerals concerned were found to be in good agreement with experimental values, with R2 values of 0.91, 0.98, 0.99, and 0.90 for mica, galena, chalcopyrite, and sphalerite recoveries, respectively. RSM combined with desirability functions and CCD was successfully applied for the modelling of mica flotation, considering simultaneously the four flotation responses to achieve the maximum recovery of mica and minimal loss of Pb, Cu, and Zn to the flotation concentrate. Keywords: chlorite, talc, flotation, response surface methodology, central composite design, optimization.
Future trends in the international Reporting Codes based on SEC's Regulations SK-1300
Authors: Rupprecht S.M.
Published: August 2021

SYNOPSIS In June 2016, the US Securities and Exchange Commission (SEC) 'proposed a revision to its disclosure requirements-related guidance under the Securities Act and Exchange Act for properties owned or operated by mining companies'. On 31 October 2018, the SEC released its adopted final rules for property disclosures for mining registrants - 'Modernization of Property Disclosures for Mining Registrants'. The amendments are aimed at providing investors with a more comprehensive understanding of a registrant's mining properties, which should help them make more informed investment decisions. The new rules replace the SEC's Industry Guide 7 as of January 1, 2021. This paper investigates how the new subpart 1300 of Regulation S-K may affect future updates to the Committee for Mineral Reserves International Reporting Standards (CRIRSCO) International Reporting Template, as well as international Reporting Codes. Critical changes such as the reporting of Mineral Resources exclusive of Mineral Reserves are discussed, the impact of third-party reporting regarding reducing Section 11 liability is considered, as is the trend of utilizing multiple qualified persons for technical reports. This paper highlights areas in the CRIRSCO and international Reporting Codes that may require consideration by Qualified and Competent Persons providing technical report summaries and Competent Persons Reports (CPRs). Keywords: SEC, 1300 of Regulation S-K, international Reporting Codes, CRIRSCO, Qualified/Competent Person, mineral reporting.
The institutional framework for the public sector of economy at the current stage of its development
Authors: Romaschenko Tatyana D. , Gersonskaya Irina V.
Published: August 2021

Subject. The basic components and the structure of the public sector of economy and its functioning in the current context are subjects of applied research of many international and Russian scientists. However, the majority of significant aspects of the institutional framework for the public sector, the classification of types and forms of state institutions in theoretical economics have not been studied enough and have been debated a lot in scientific literature. One of the most controversial issues in economics is the rationality of the formation of an institutional framework for the public sector. Therefore, the study of issues related to the functioning of the public sector and its development as the main state institution is objectively important for the formation of prerequisites for the sustainable economic and social development. Objectives. The purpose of the research is to study the institutional system of the public sector within the national economy and to consider its basic structural elements and its functioning aimed at improving the public welfare. The article presents a classification of public institutions by hierarchical structures and their main functional features, i.e. public administration, public enterprise, and public social services. Methods. The research was conducted with a help of a set of scientific methods and research techniques: dialectical logic, the cognition of objective reality, scientific abstraction and analysis. Also, an institutional and systemic approaches to the “public sector” category were used. The study involved an assessment of relevant scientific publications in theoretical economics. Conclusions. The conclusion was made about the leading role of public institutions in the social and economic system of the national economy. The public sector institution has a dual nature, since it is both a subject and an object of public administration. It was found that as a subject of administration the public sector acts as the main regulator of social and economic relations in the national economy, and as an object of administration it functions as an economic entity that performs a variety of functions and carries out its activities in accordance with state standards. It is advisable to classify the institutional framework for the public sector of the economy by the types of state activities, which characterise its horizontal structure, i.e. public administration, public enterprise, and public social services. Such structure is also classified by a hierarchic feature and makes up a vertical structure of state institutions: public institutions of a higher, middle, and lower levels. The activities of the public sector institutions are subordinate to the achievement of the established state goals, which take into account public interests and are aimed at the sustainable development of the social and economic system of the national economy.

Registers of Practices as an Evidence-Based Social Policy Mechanism for Child Welfare: An Analysis of International Experience
Authors: Busygina N.P. , Podushkina T.G. , Freik N.V.
Published: August 2021

The article analyses the international experience of establishing evidence-based practice registers. Such registers are considered not as a “container” of once and for all selected “best practices”, but as a permanent mechanism of evidence-based social policy. Using the material of registers developed in the USA and the UK, the analysis of the most important structural components of the registers is carried out, with the main focus on the methodology and procedure of practice selection. The authors question the hierarchy of research methodologies and show that experimental design (randomized controlled trials) can be recognized as the “gold standard” of research only under certain conditions — if a linear, simple theory of change is adopted, while the adoption of a complex theory of change requires other research strategies and methods. Based on the analysis, several priority tasks are formulated that need to be addressed in order for the national register of practices being created in Russia to comply with the principles of evidence-based social policy.

Con el objetivo de determinar la presencia de enterobacterias productoras de betalactamasas (bla) en muestras de efluentes hospitalarios, se realizó un estudio en dos hospitales de nivel II y III de Lima, Perú. Se identificó y caracterizó el perfil de resistencia de las bacterias aisladas mediante el sistema MicroScan para 18 antimicrobianos, y mediante PCR convencional se determinó la presencia de los genes de resistencia a betalactamasas de espectro de extendido (BLEE) (blaCTX-M, blaSHV, blaTEM, blaPER) y carbapenemasas (blaKPC, blaNDM, blaVIM, blaIMP). Se identificó 32 aislados (20 enterobacterias y 12 bacterias gramnegativas). Todas las bacterias aisladas presentaron multirresistencia. Se halló la presencia de genes BLEE (blaTEM) y carbapenemasas (blaKPC e blaIMP) en los hospitales evaluados. La liberación de estos microorganismos a la vía pública y la falta de tratamiento de los efluentes hospitalarios podría ser un importante problema de salud pública.

Objetivo: Describir las características de los pacientes adultos con tuberculosis (TB) y diabetes mellitus (DM) en el Perú, y explorar la asociación de la DM y la mortalidad en personas con TB. Materiales y métodos: Se realizó un análisis secundario de la base de datos del Sistema de Información Gerencial de Tuberculosis de la Dirección de Prevención y Control de Tuberculosis del Ministerio de Salud de Perú. Se incluyeron aquellos pacientes adultos que iniciaron tratamiento con el esquema de TB sensible a los medicamentos los años 2016, 2017 y 2018. Se realizó un análisis descriptivo de los pacientes con TB con DM y un análisis exploratorio para evaluar la asociación de la DM con la mortalidad usando una regresión de Poisson para determinar el riesgo relativo (RR). Resultados: Se registraron 67 524 adultos con TB sensible a los medicamentos, de los cuales se reportaron 6529 (9,7%) personas como TB con DM y 4048 (6,0%) con infección por VIH. De los pacientes reportados con TB con DM, la mayoría eran hombres (60,2%) con una mediana de edad de 53 años. Con relación a la mortalidad, las personas con TB con DM tuvieron una mayor frecuencia de muerte comparado con aquellas personas con TB sin DM (7,2% vs. 5,4%). En el análisis exploratorio de factores asociados a la mortalidad, la DM presentó un RR crudo de 1,32 (IC 95%: 1,20-1,50); sin embargo, esta asociación varió en el modelo ajustado con un RR de 0,93 (IC 95%: 0,84-1,04). Conclusiones: La DM es la comorbilidad más frecuente en pacientes con TB en el Perú, aunque no se encontró asociación con una mayor mortalidad.

Con el objetivo de determinar la frecuencia de aislamientos de Staphylococcus aureus meticilinorresistente adquirido en la comunidad (MRSA-AC) y describir el patrón de resistencia antimicrobiana y de genotipo, se realizó un estudio transversal en el 2017 en el Hospital Nacional Cayetano Heredia en Lima, Perú. De los 115 aislamientos de S. aureus analizados, se determinó una frecuencia de MRSA del 46,1%, la mayoría provenientes de secreciones de diferentes tipos (26,4%) y sangre (18,9%). Se encontró alta corresistencia (75%) a clindamicina, eritromicina, gentamicina y ciprofloxacina entre los aislamientos de MRSA. Según la tipificación de SCCmec, la mayoría correspondían a cepas de MRSA adquirido en un hospital (MRSA-AH) y, solo un pequeño grupo (2,6%) correspondían a MRSA-AC. A pesar de la baja frecuencia descrita con relación a países vecinos (27%), es necesario mantener una adecuada vigilancia epidemiológica local para evitar la propagación local de MRSA-AC.

Authors: SAKHRI N. , MENNI Y. , AMEUR H. , CHAMKHA A.j.
Published: August 2021

Earth to air heat exchanger EAHE is a renewable technique based on a geothermal source. Arid regions are characterised by hard winter and summer weather conditions, which lead to a large thermal discomfort for the big part of the year. In this paper, we study by experiments the performance of stand-alone earth-to-air heat exchanger without external devices (fans, etc.), but only with the local climatic conditions of the region of Bechar (located in the Southwest of Algeria). The EAHE contains a PVC pipe with 66 meters of length and 110 mm of diameter, and it is buried at a depth of 1.5 m in an agriculture zone, where the annual undisturbed sub-soil at 1.5 m is 28°C. The stand-alone EAHE has the capacity to raise the air temperature by 10°C in the heating regime and reduce it by 11.9°C in the cooling regime. Furthermore, the relative humidity is raised by19% in the humidification regime and reduced by 27% in the dehumidification regime. The daily working regime was: 62.5% of heating (from 00h to 08h and from 18h to 23h) and 37.5% of cooling (from 09h to 17h) for the thermal regime, 62.5% of dehumidification (from 00h to 09h and from 18h to 23h) and 37.5% of humidification (from 10h to 17h) for the hygrometric regime. The stand-alone EAHE technique presents a great potential for the pre-heating, pre-cooling, and natural ventilation of dwellings and buildings in arid regions.
A review on effect of various artificial roughness on heat transfer enhancement in a channel flow
Authors: PANDA Sudharani , KUMAR Rakesh
Published: August 2021

Heat transfer improvement plays a vital role in several industrial applications as well as in the transportation sector such as gas turbines, heat exchangers, various cooling devices, and combustor liners. The extensive research to enhance the heat transfer rate in various sectors has been carried out to achieve the objectives such as (i) to increase the system efficiency, (ii) to reduce thermal load, (ii) to reduce consumption of non-renewable energy, (iii) to reduce the production of emission, (iv) to develop new green technologies, (v) to lower energy prices for the consumer. The heat transfer in various sectors has been carried out by adopting three different ways (i) increasing the surface area of the heat transfer systems, (ii) enhancing the fluid properties, (iii) by adding extra surface on the heat transferring surface. This article aims to deliver a comprehensive review of the current research on heat transfer enhancement techniques by using artificial roughness elements such as rib tarbulator, fin, and dimple. It includes various types of rib tarbulators, fins, and dimples used for heat transfer enhancement of gas turbine blades of the power plant, combustion liners as well as solar air heaters. The physical mechanism responsible for heat transfer enhancement in various artificial roughness elements has been discussed and compared. The challenges and difficulties associated with the heat transfer techniques have been discussed. The parameters such as dimple depth, channel height to dimple imprint diameter, pitch, the density of artificial roughness element, arrangement of artificial roughness, relative roughness pitch, relative roughness height, angle of attack on flow, mass flow rate, Reynolds number on thermal performance, thermohydraulic performance, flow structure, friction characteristics have been studied and compared. From the comprehensive review, it may be recommended that the teardrop shape dimple can be used for further enhancement of heat transfer as compared to other artificial roughness elements. In the future, this teardrop may be used to enhance the heat transfer in the solar thermal system and some other relevant thermal systems.
Integration of Knowledge (IoK) Methodological Reasoning of Islamic Economics (IE) as the Wisdom of Humanity: A Heterodox Economic Approach
Authors: Omercic Jasmin
Published: August 2021

The world increasingly needs an alternative approach to economic development. This paper endorses the Integration of Knowledge (IoK) approach as the wisdom of humanity through Islamic Economics (IE). A review of relevant literature through qualitative methodologies of library research, discourse and critical content analysis highlights the civilisational practices of integration, how development of economics diverged from such practices and how heterodox approaches reacted to such divergence. A section on learning the wisdom of humanity from each other emphasizes the inevitable historical civilizational integration (IoK) and exchange of knowledge. It follows with a literature review of the development of mainstream economics, how it abandoned such historical civilizational practice and its sound foundations, namely ontology, epistemology, axiology and methodology. A highlight of heterodox economics (HE) responses reveals the alternatives to the mainstream-focused positivistic approach to economics. The inadequacy of those alternatives led us to demonstrate Muslim responses and the centrality of IE as a comprehensive alternative heterodox economic approach. The analysis shows how IE grew along Islamisation of Knowledge (IOK) as two parallel and major intellectual iṣlaḥ (reform) and tajdīd (renewal) movements. A brief review of the development of each shows the potential of IE’s IoK methodological reasoning to revive the IoK approach in economics as the wisdom of humanity. The sound IE philosophical foundations, namely ontology, epistemology, axiology and methodology, have a major impact in that process. Thus, utilising the core IoK objective within IOK together with IE contributions shape the process of overcoming problems and issues of mainstream economics. Actionable recommendations to practitioners and academics depict how the IE approach to economics could be implemented and sustained along SDGs agenda.
Outcome assessment for pyeloplasty in pediatric age group on the basis of ultrasonography

Published: August 2021

At present, duration and methods of radiographic follow-up after pediatric pyeloplasty are not well defined. We prospectively studied pediatric age group patients to assess outcome for cases of pyeloplasty on the basis of ultrasonography and DTPA scan.

: We assessed all cases of PUJ obstruction in age group 0-18 years, who got admitted in LLR hospital, Kanpur and underwent pyeloplasty. Patients were excluded if cause of pyeloplasty was acquired. Preoperatively patients underwent clinical evaluation with history and examination followed by radiological investigations including Renal USG & DTPA scan. All patients were followed up postoperatively at 3, 6, 9 & 12 months. In USG, renal parenchyma thickness, antero-posterior diameter of renal pelvis was assessed. In DTPA scan, differential renal function was assessed. Data of USG and DTPA scan were statistically compared.

32 patients who underwent pyeloplasty at a median age of 4.2 years were studied. Follow-up was done for 1 year. On the basis of our study, DTPA scan is better than renal USG to assess functional outcome after pyeloplasty in pediatric age group up to 6 months during follow-up. But results are comparable for follow-up during 9 & 12 months postoperatively. The results of our study show that in the first 6 months, renal USG is not as much informative as DTPA scan to assess functional outcome after pyeloplasty but after 6 months, renal USG is equally effective as DTPA scan.

Our study concludes that for poor resource countries, renal USG can be used to assess functional outcome after pyeloplasty in pediatric age group for post-operative follow-up, instead of costly & scarcely available investigation like Renal DTPA scan.

Authors: Singh Neeta
Published: August 2021

The Present study was conducted in the Department of Pediatrics of Lala Lajpat Rai & Associated Hospital GSVM Medical College, Kanpur. All the children aged between 1-5 years, admitted in Department of Pediatrics were asked to participate in this study. Information regarding vaccination, socio-demographic factors was collected from their parents and care takers. Accuracy and validity of information were confirmed by immunization card in possible situation and inspection for BCG scar.

Hospital based descriptive cross-sectional study.

In upper class, 100% of children were completely immunized. In upper middle class, 80.8% children had complete and 19.1% partial immunization status. No one remained unimmunized in upper middle class. In lower middle class, 33.9% of children were completely immunized, 59.6% partially immunized and 6.4% remained unimmunized.Children who were 1stin birth order, had maximum immunization coverage (44.8%). Minimum immunization coverage was in birth order >4 (3.2%). P value is <0.001, indicates the significant relation between birth order and immunization status. As birth order increased, immunization coverage decreased.

In this present hospital based descriptive cross –sectional study, we found that 51.2% children were fully immunized, 45.6% were partially immunized and 3.2% children were unimmunized as per National immunization schedule. Children belonging to upper class were 100% completely immunized. In upper middle class 80.8% children in lower middle class 33.9%, in upper lower class 55.7% and in lower class 50.9% children were completely immunized respectively. In lower class immunization coverage was higher than lower middle class. Droprate for BCG to pentavalent 1 was 10.64%, similarly dropout from BCG to measles was 12.7%. Dropout rate of pentavalent 1 to pentavalent 2 was 1.4%, pentavalent2 to pentavalent3 was 2.6%. It indicates that system is not able to hold the child once registered. Steps for improvement should focus on reducing the drop rate from BCG to pentavalent and measles.

Published: August 2021

The term Big Data has gained popularity in recent years due to technological developments and the accumulation of data from various sources, mobile devices and sensors. Hbase is a distributed open source environment that uses available disk space optimally and efficiently based on data. It organizes data in a very different way from standard relational databases and works with both structured and unstructured data. This article describes our experience and research on how the execution time for inserting datasets and selecting data depends on the size of the data volumes, the locations (nodes of the same or different networks) from which they send or retrieve and what is the effect of the selected data organization (especially RowKey design) on the execution time.

Redox flow battery technology has been known since the 1970s. Their low specific characteristics have been of interest for a long time. Practical interest has arisen in recent decades because of the intensive development of alternative energy (such as solar and wind) and the regulation of peak loads in industrial networks. It turned out that large-scale energy storage systems used for compensation of fluctuations in the generation of energy by the sun and the wind, while producing electric vehicles and power supply systems for large households, are more profitable when they work on flow redox batteries. Firstly, they are easily scalable, and secondly, the energy stored in such batteries is cheap. Since the expansion of the scope of practical use of flow batteries has taken place in recent years, researchers continue to work on increasing the economic efficiency of flow batteries and on the search for more efficient redox systems. One of these areas is the use of cheaper redox systems of organic nature, in particular, quinone, anthraquinone and their analogs. Their high water solubility, well-separated oxidation-reduction potentials, which practically eliminate water splitting, their stability, safety, and low cost on a scale of mass production are the most important characteristics for new aqueous organic electrolytes. So far, organic redox flow batteries are still inferior to vanadium and other inorganic redox batteries in terms of their operational parameters. This drawback hinders their development on industrial scale. However, the results shown in this review can help scientists to improve them and commercialize in the future.

The structure and specific electrochemical characteristics of a mixed cathode material based on ground LiNi1/3Mn1/3Co1/3O2 (NMC111) and highly porous activated carbon YEC-8B were studied. The mixed material containing 35 wt. % NMC111 and 65 wt. % YEC-8B (based on the mass of active materials), has a specific capacity ∼70% higher in comparison with the cathode material based on pure coal YEC-8B. It was shown that while cycling a lithium-ion supercapacitor with a cathode based on this mixed material at high current densities, no significant changes took place in the electrochemical characteristics of the material. It was demonstrated that this type of cathode material has two advantages: at low current densities it displays the charge-discharge properties of the cathode material of a lithium-ion battery with high specific energy, and at high current densities, it functions as a material of a supercapacitor with high specific power.

Transformation of the image of power on the medals of the last Valois during the Religious wars
Authors:   Institute of History and Politics, Moscow Pedagogical State University, Loshchilova Tatiana N.
Published: August 2021

The article is devoted to the study of images of Royal power that were used by the last Valois dynasty’s representatives, reflecting the transformations that occurred in connection with the attempt to strengthen the Royal authority with intensification of secular power and gaining spiritual power. Studying the French Royal medals of the end of the XVI century, it is possible to identify the main trends of changes in the image of the Royal power during the development of religious conflict, demonstrating the increasing role of certain Christian symbols that were used both to indicate their religious position and its presentation to society during the state crisis. The study analyzes the medals of the time of Charles IX, in particular in memory of St. Bartholomew’s night, and the medals of Henry III. Analysis of these images allows us to come to the conclusion about the evolution of ideas about the king and his power from the image of the ancient hero king that was formed at the time of the beginning of religious wars, to the restoration of the idea of the most Christian king and peacemaker king, common in the pre-Renaissance era, and which is most clearly shown in the images of Henry III.
Religious views of Cardinal Gabriele Paleotti on sacred art
Authors:   Moscow Pedagogical State University, Nosova Ekaterina S.
Published: August 2021

Being founded upon the book «Instructions on religious and secular images» (1582), the article examines cardinal Gabriele Paleotti’s views on sacred art. The author explores the issue of perception of painting as a God-pleasing art, exposes the ideological aspect of sacred painting and reveals the cardinal’s complex evidence base on the need for the existence of religious images in churches and their significance in the life of every person. It is concluded that objects of art should be perceived not only as an artistic commentary on the text of Holy Scripture, but also as a prayer image that plays a cohesive role in interlocution with God.

Genus Tremabolites Zittel, 1878 (Porifera, Hexactinellida)
Authors:   Saratov State University, Pervushov Evgeniy M.
Published: August 2021

Tremabolites sponges known among the Middle-Late Cretaceous beds in Europe are reliably identifiable due to the numerous openings against the background of the skeleton smooth upper surface. The ideas of the level of organization in these sponges and of the species characteristics are far from being univocal. The paper deals with the species diversity of Tremabolites common in the Coniacian – Santonian rocks from the Volga Region. Examples of regeneration and budding in the representatives of the group are presented.

Published: August 2021

The article presents the methodology of the representative elementary volume definition for two 1 m long whole core segments. Scientific articles focused on practical methods of representative volume calculations using various physical parameter fluctuations have been studied. Porosity values of every whole core fragment evaluated in two ways using the 7.3 cm diameter core samples in the first approach and the 3 cm diameter core samples in the second one have been compared. Particularities of the scale effect occurring in core samples and depending on core size and porosity type have been analyzed. The cause of porosity increase in big core samples has been determined. The reason due to which porosity changes are explained by fracture porosity occurring in core samples having big volumes has been found. The comparison between neutron log porosity and core porosity has been made. Reasons of similarities or differences of core and log data have been established.

Published: August 2021

The article presents the analysis of the inner structure of the salt-bearing series within the Caspian Depression. Certain salt-bearing complexes of various ages, compositions and plastic properties are distinguished. Their structural relations and the features of salt-tectogenesis manifestation are evaluated. Up to the present no subsalt uplifts have been confirmed in the Russian sector of the Caspian Depression and no HC fields have been discovered. Therefore, any search for additional criteria for predicting the salt-bed structure from the character of salttectogenesis manifestation is conductive to predicting the zones of subsalt structure development over the Caspian Depression area.

The relevance of the study is conditioned by rapid transition to digital forms of education, which is associated with the pandemic. Students have changed the way they interact with teachers and with each other, which constantly leads to transformation of personal meanings, values, rethinking of their purpose and role in the educational process. The purpose of the study, presented in the article, is to investigate unusual characteristics of the semantic sphere regarding male and female students’ academic activity. Hypothesis: semantic content of academic activity differs in male and female students. Participants are first-year full-time students, studying at the Faculty of Psychology, Faculty of Engineering and Economics and Faculty of Human Resources Management (N = 102, aged from 18 to 22 years, 52 participants are female students and 50 participants are male students). The participants were tested using Life-Purpose Orientations Test (D. A. Leontiev) and the Ultimate Meanings Technique (D. A. Leontiev). Based on the latter methodology, the entire sample was divided into five groups depending on the presence of a certain meaning. The conjugation of ultimate meanings and gender was determined using φ-Pearson criterion, while MANOVA criterion helped to investigate differences in life-purpose orientations depending on gender and ultimate meanings. We established differentiation within ultimate meanings in education depending on gender of a student: men are focused on respect and safety, while women are focused on getting pleasure and gaining confidence. We found that women connect getting pleasure and gaining confidence while learning with monitoring their lives, whereas male students connect it with the ultimate meanings of security and respect, satisfaction with their own lives and the feeling of being able to influence their life. The obtained results can help to draw the following conclusion: development of the individual system of life-purpose orientations and its functioning in the educational situation are interconnected with gender as one of the most essential biosocial characteristics of an individual.
