Throughout human history, gold has been the most sought-after and well-known precious metal in the world. It is synonymous with wealth in the financial market and jewellery. However, its use has a wide range of applicability in biomedicine, electronic engineering and other industries. Primary gold resources are limited and have been significantly depleted in recent decades. To cover the current demand, it is necessary to process secondary sources containing gold such as heaps, tailings, lean ores or electrical waste. New and especially more efficient technological procedures are needed for the processing of these secondary sources. From an environmental point of view, a hydrometallurgical process is considered to be more appropriate than a pyrometallurgical process, in which very toxic fumes enter the air. This work investigates the leaching of gold from flotation wastes using thiourea. It is flotation waste that is the target group of materials that are a source of precious metals. An interesting gold content is present in our waste sample (Hodruša Hámre tailings pond), but its evaluation depends on the setting of suitable technological conditions. In this work, thiourea is used as an alternative leaching agent to toxic cyanide, which is banned in Slovakia and many countries around the world due to its high environmental risk. The results of the study are described with respect to the gold recovery under optimized thiourea leaching conditions.

Considers the problem of the Orthodox religious identity from the point of view of the influence of five types of discourse, widely represented in the Orthodox semiotic picture of the world: philosophical, mythological, artistic, political and ideological. Selected types of religious identity: normative, marginalized, and folkloristically, and determined what type of discourse most pragmatically strongly influences the formation of a type of Orthodox identity. The authors come to the conclusion about the existence in the Russian Federation "rural" and "urban" Orthodox discourses. The first leads to the development of social strain in the area of religious identity and is the base of the formation polarisierung religious identity. The second sets the normative Orthodox identity, avoiding archaism and development of the centaur-ideas. This study was conducted in part supported by RFBR, research project No. 18-011-00164 on "Discursive study of religious identity." Designed for a wide range of sociologists, philologists, cultural studies and religious studies, as well as for a wide circle of readers interested in questions of religion.

Entrepreneurship has become one of the vital activities for economic development. It is synonymous with job creation, innovation, improvement in the societal well-being and economic growth in developed and developing countries alike. There is great interest in entrepreneurship globally as well as in Malaysia. Over the past few years, many individuals, as well as families, are actively engaged with the small business. Also, in light of the 2013 GEM study, 12.7% of Americans are effectively occupied with beginning a business or are the proprietor/director of a business that is under three years of age. Simultaneously, the Halal industry, that represents the global Islamic economy, is the fastest-growing market in the world with $2.3 trillion market value. Halal entrepreneurs (Halalpreneurs) are the major contributors to this achievement as they constitute a significant portion of the total establishment in most of the Muslim countries. That is the reason Entrepreneurship has turned into a conventional term that depicts a wide range of practices that include being innovative, devilish and tricky. Entrepreneurship has been defined by many scholars, researchers, industry players, and academicians globally which have also been perceived in the same way by most of the economies around the world. However, the Islamic economy looks at the concept of ‘entrepreneurship’ in a different way and perceives it as ‘Halalpreneurship’. To define entrepreneurship in the halal industry, although, the term ‘Halalpreneurship’ is being used, surprisingly the term has not been defined properly yet. It is essential for the Muslim entrepreneurs to have a proper understanding of Halalpreneurship from Maqasid-al-Shariah perspective. Such point of view is crucial to justify the term in the Halal industry and differentiate from conventional entrepreneurs. On this context, this paper provides concept and definition of Halalpreneurship justifying from the perspective of Maqasid-al-Sharia’h. It also identifies the differences between Halalpreneurs and entrepreneurs using secondary resources available in the forms of literature, research papers, journal papers, articles, conference papers, online publications, etc. The findings of the study will clarify the concept of Halalpreneurship from Maqasid-al-Sharia’h perspective and recognize Halalpreneurs distinguished from conventional entrepreneurs.

Zoonoses caused by diverse etiological agents, are important from public health and economic point of view, and are reported in humans and animals from developing and developed nations of the world. Cryptosporidiosis is an emerging food and waterborne zoonotic protozoan disease that has been detected in both human and animal populations all over the world. The source of infection is exogenous, and the ingestion of contaminated food and water is the principal mode of transmission. The oocysts of Cryptosporidium are abundant and pervasive in ambient water, where they can survive for months. It prefers epithelial cells found in the digestive tracts of a wide range of hosts. Waterborne transmission through drinking water or a swimming pool is common, resulting in outbreaks in several nations throughout the world. The disease can manifest itself in sporadic or epidemic forms. The infection has been recorded in immunocompetent and immunocompromised individuals. The watery diarrhea, abdominal cramps, nausea, anorexia and low grade fever are most commonly observed symptoms. The laboratory help is required to make an unequivocal diagnosis of disease. The preventive strategies include excellent hygienic measures to avoid the contamination of food and water by oocysts of Cryptosporidium. In addition, the role of veterinarian is highly imperative for the management of disease in domestic animals.

The stages of development of the world economy and the peculiarities of the functioning of countries in the world, which are inherent in different time periods, are: changes in trends, emergence and increase of socio-economic and socio-political contradictions, importance of certain key factors for the formation of a policy of managing territorial development under different conditions, all this has led to the emergence of a number of spatial development theories. The authors of theories and models of spatial development considered the development of territories from the point of view of a wide range of factors of influence: geographical, administrative, economic, social, political, innovative, etc., characteristic of different time periods. An effective management of territorial development in modern conditions is becoming relevant in terms of the need not only to solve existing problems, but also to expand opportunities for self-development of territories. The implementation of theoretical provisions of spatial development theories has found a practical reflection in different historical periods of the economy of different countries. Theories of spatial development form the basis of the methodology of public administration, which determines the principles, directions of formation and ways to ensure the functioning of organizational structures and relevant mechanisms, models of development and management, approaches to the use of resources, etc. With the help of spatial theories one explains and anticipates trends, develops models and mechanisms of territorial development, forms instruments for their practical implementation. Due to the importance, complexity and interdependence with a whole range of socio-political, socio-economic, ecological and other processes, the issues of theoretical approaches to the formation and functioning of the optimal model of spatial development constantly remain in the field of view of researchers and practitioners of the world, which further determines the prospects and relevance of studying the defined topic.

An analysis of the various aspects of one of the most significant disasters of the 20th century — the collapse of the USSR for many decades will be of interest to researchers of different scientific fields and schools. Representatives of almost all branches of humanitarian knowledge — historians, sociologists, political scientists, and merely indifferent people whose fate was directly affected by this epoch-making event, seek to comprehend the history of the death of the USSR, to understand the essence of destructive processes, to find answers to the question about the premises, causes, mechanisms and consequences of the collapse of the first socialist state in the world. By now, there are a large number of journalistic materials not burdened by the source research or analytical assessment. Scientific research, as a rule, belongs to the pen of historians, however, even here the analysis of the causes of the death of the largest state on the world stage is primarily affected by the subjective factor, ideological bias, and the involvement of the authors of the works in political events. In an attempt to answer the question, many contradictory theories have been put forward, including conspiracy theories explaining the “secret springs” of the death of the Soviet Union. However, such a multifaceted political event, caused by a wide range of reasons, which marked the beginning of a new round of Russian history and the foundation of our days, is practically not explored from the standpoint of economic analysis, competition, and the struggle for the sales market action. The author does not set as his task a comprehensive study of such a multifaceted problem — the problem of the death of the USSR. The article presents an attempt to identify the economic component and recall the tragic consequences of the death of the Soviet Union. The work substantiates the point of view according to which the problem of the dialectics of the collapse of a state of conscience needs a comprehensive, impartial and versatile study that can help find answers to today’s problematic questions.

At the end of 2019, the world was shaken by the discovery of a new coronavirus strain (SARS-CoV-2), which was identified to be the source of the outbreak that originated in China. The outbreak, which was subsequently named COVID-19, was declared as a pandemic by the World Health Organisation and has adversely affected and impacted upon many countries, not only from the aspects of medical and health care services, but also with respect to economic stability, financial management and social security. The treatment of COVID-19 patients is costly and involves limited resources, particularly in the case of critically ill patients who require mechanical ventilation. Thus, medical practitioners are faced with complex issues in justifying the distribution of health care resources to deserving patients. This article seeks to discuss the concept of justice in the distribution of health care resources from the bioethical and Islamic standpoints. The research employs the qualitative method of doctrinal analysis, which comprises primary and secondary sources relating to the principle of justice in contemporary medical ethics and from the sharīcah point of view. Findings of this study illustrate that there exist similarities between the two perspectives, which among others, include the agreed nexus between the allocation of scarce resources to patients and deliberations on the futility of medical treatment. Abstrak Pada penghujung tahun 2019, dunia digemparkan dengan penemuan strain coronavirus baru (SARS-CoV-2) yang dikenalpasti sebagai punca wabak absah yang bermula di China, yang kemudiannya dinamakan COVID-19. Wabak yang telah diisytiharkan sebagai pandemik oleh Pertubuhan Kesihatan Sedunia ini menjejaskan dan memberi impak yang signifikan terhadap kelangsungan sesebuah negara bukan sahaja dari aspek perkhidmatan perubatan dan penjagaan kesihatan, tetapi juga dari segi kestabilan ekonomi, pengurusan kewangan dan keselamatan sosial. Rawatan pesakit COVID-19 melibatkan kos yang tinggi dan sumber yang terhad, terutamanya pesakit-pesakit kritikal yang memerlukan alat bantuan pernafasan. Oleh itu, pengamal perubatan berhadapan dengan isu-isu yang kompleks tentang kewajaran pengagihan sumber yang terhad kepada pesakit yang berhak. Makalah ini bertujuan untuk mengupas konsep keadilan dalam pengagihan sumber perubatan dari sudut pandangan bioetika dan bagaimana Islam menangani isu tersebut. Kajian ini mengaplikasi metode kualitatif iaitu analisa doktrin yang merujuk kepada sumber-sumber utama dan sekunder berkaitan prinsip keadilan di dalam etika perubatan moden dan dari sudut pandangan sharīcah. Hasil kajian mendapati bahawa terdapat persamaan di antara kedua-dua perspektif tersebut, antaranya justifikasi pengagihan sumber perubatan yang terhad berkait rapat dengan pertimbangan tentang rawatan perubatan yang tidak membawa apa-apa manfaat (futile treatment).

The development of folk crafts in Russia was closely connected with the formation of handicrafts museums that performed complex tasks of preserving, studying and promoting folk art. The study of their history today is one of the problems that have not yet been sufficiently studied in museology. Handicrafts museums were considered by researchers primarily in the general historical context of the influence of state policy and provincial zemstvos on the development of handicraft industry in Russia. However, the phenomenon of handicrafts museums remains insufficiently studied from the point of view of history and the theory of museum work. The type of the handicrafts museum has not yet been singled out as an actual form of the museum institution of the last quarter of the XIX – the first third of the XX centuries, which spread in several provinces of the Russian Empire. The purpose of the article is to review the main activities of the Moscow Handicrafts Museum - an example of the formation of new types of museums in Russia and their influence on the development of folk crafts in the second half of the 19th century – the first third of the 20th centuries. Moscow Handicrafts Museum opened in 1885. His task was to fully promote the development of folk art and the implementation of handicrafts. One of the main features and goals of creating the Handicrafts Museums in the Russian Empire was the formation of an established system of state patronage over the peasants who were freed from serfdom and promotion of their involvement in the new sector of the economy. The museum staff formed the museum collection, actively participated in organizing the training of folk craftsmen, arranging production workshops, became intermediaries in the art market, and was engaged in active exhibition work around the world, especially at large industrial fairs. In the 1890–1910s, the case started in Moscow spread quickly to almost the whole country. Handicrafts museums immediately arose in several provinces of Russia. One of the program documents of that period was the concept of the development of the Handicrafts Museum, proposed in a report of Sergey Morozov in 1910. Thus, at the beginning of the twentieth century in Moscow, the structure of an effective museum was formed, aimed at systematic work with folk crafts and successfully involving a wide range of partners: artists and scientists, merchants and foreign industrialists. Thanks to the assistance of handicrafts museums in Russia in the late XIX – early XX centuries traditional folk crafts were able to survive and be adequately represented throughout the world. The aesthetic significance of folk art has been recognized. The study of folk art has become an important subject of scientific research. All aspects of the multifaceted history of the formation and development of handicrafts museums and their role in the socio-economic and cultural development of Russia are of great scientific interest and require careful further study.

The article is devoted to the image of a woman in the Azerbaijani-Turkic picture of the world. It is noted that this concept is complex and ambiguous. The central concept representing an image of the woman in Azerbaijan-Turkic Paremiology is “woman” which in language consciousness of the people associates with a word arvad. In the Azerbaijan language the word qadın which, however, is not comparable to a lexeme arvad neither from the point of view of common use, nor from the point of view of the associations steadily characterizing a place of concept of a language picture of the world is common also. The connotation of linguistic units serving the verbalization of the concept of “woman” is divided into positive and negative. One would assume that the negative connotation is associated with Islamic influence, but the facts indicate the national character of the ideas. Islamic mentality, on the contrary, gives women a place of honor in the world. Most likely, the concept as a whole is affected by the masculinity of the concept. It should also be noted that in the language the manifestation of the concept “woman” is dynamic, it is represented in a wide range and varies both in the semantic and stylistic terms.

India, one of the emerging economies of the world, is plagued with preva-lence of inadequate and poor sanitation facilities. Unhealthy hygiene practices and menace of open defecation still persist in the country which seeks to be counted as one of the superpowers. While some of the poor countries of the world fare better than India in terms of sanitation, it becomes essential to look beyond economic factors to understand the problem. The problems are manifold and appear in many dimensions. While sixty percent of popula-tion does not have access to toilet facilities, the instances of non-utilisation of existing toilet facilities are also reported. The non-utilisation of existing toilet facilities may range from planning related concerns to attitudinal issues. The planning or policy related concerns stem from problems related to maintenance of toilets, lack of plumbing and drainage facilities, lack of water and sewage systems etc. To understand these problems and the efforts to address them, critical evaluation of sanitation policies is needed. Sanitation policies and perceptions of masses towards sanitation practices can be complementary factors for cost of access to sanitation facilities. This paper seeks to look into the factors affecting inadequate sanitation facilities from a broader point of view focussing on policy and practices. The paper utilises secondary sources and a case study to unravel the factors and their interlinkages.
