A technique has been developed of justification of possibility and expediency of extraction of the reserves left, which were mined more than 40 years ago by chamber system with maintenance in a safe condition of underground mining constructions. The methodology includes the identification by studying the geological and mine surveying documentation of districts with reserves in the mine fields; calculation of volumes and quality indicators of reserves left at these areas; assessment of a condition of mine workings that have direct access to the reserves concerned, and the possibility of their re-use, as well as the possibility of new development workings and ensuring their sustainability and maintenance in a safe condition; establishing the features of geomechanical processes in the rock mass and the presence of dangerous violations in the worked-out zone, the degree of the violation and the nature of the deformation of rigid and pliable pillars in the extraction chambers, including the use of specially conducted  mine openings; development of technological schemes for safety extraction of abandoned minerals. With the use of this technique for the first time the technological opportunities and economic feasibility of mining minerals from the treatment units of the First and Second Mines of JSC Belaruskali, worked out more than 40 years ago, has been estimated. The possibility of excavating abandoned reserves in the sylvinite layer 4 and layers 2, 2–3, 3 in inter-chamber pillars in areas previously worked out by the chamber system with total volumes of more than 57 million tons is shown. The results of surveys of the state of capital and development workings are given, according to which for the re-mining of most of the worked-out blocks, new capital and development workings will be required. The results of visual examinations of panel and block drifts, their conjugations with treatment passages, as well as the state and degree of violation of inter-passage and inter-chamber pillars in the treatment chambers are described. Possible methods for re-mining the reserves of the Third potash horizon with treatment longwalls and a chamber system are proposed, which are distinguished by high technical and economic efficiency and mining safety.

Abstract:The state of the art is summarized showing many efforts but only few results which can serve as demonstration examples for developing countries. Education in health informatics in developing countries is still mainly dealing with the type of health informatics known from the industrialized world. Educational tools or curricula geared to the matter of development are rarely to be found. Some WHO activities suggest that it is time for a collaboration network to derive tools and curricula within the next decade.

What is an underground? Is it possible to embed this particular way of life into any definition? After all, even underground did not have the need to define itself at the beginning. The presented text represents a brief reflection of the development of underground in Czechoslovakia; attention is paid to the impulses from the West, which had a significant influence on the underground. The text focuses on the key events that influenced the underground. For example, the “Hairies (Vlasatci)” Action, which took place in 1966, and the State Security activity in Rudolfov in 1974. The event in Rudolfov was an imaginary landmark and led to the writing of a manifesto that came into history as the “Report on the Third Czech Musical Revival.”

This chapter considers the history of Andaman migration from the institutionalization of a penal colony in 1858 to the present. It unpicks the dynamic relationship between the state and the population by investigating genealogies of power and knowledge. Apart from elaborating on subaltern domination, the chapter also reconstructs subaltern agency in historical processes by re-reading scholarly literature, administrative publications, and media reports as well as by interpreting fieldwork data and oral history accounts. The first part of the chapter defines migration and shows how it applies to the Andamans. The second part concentrates on colonial policies of subaltern population transfer to the islands and on the effects of social engineering processes. The third part analyses the institutionalization of the postcolonial regime in the islands and elaborates on the various types of migration since Indian Independence. The final section considers contemporary political negotiations of migration in the islands.

This essay is in four parts. The first offers a critique of James Elkins and Michael Newman’s book The State of Art Criticism (Routledge, 2008) for what it tells us about art criticism in academia and journalism and feminism; the second considers how a gendered analysis measures the “state” of art and art criticism as a feminist intervention; and the third, how neo-liberal mis-readings of Linda Nochlin and Laura Mulvey in the art world represent feminism in ideas about “greatness” and the “gaze”, whilst avoiding feminist arguments about women artists or their work, particularly on “motherhood”. In the fourth part, against the limits of the first three, the state of feminist art criticism across the last fifty years is reconsidered by highlighting the plurality of feminisms in transnational, transgenerational and progressive alliances.

The Judicial Council and Its Objectives. My assignment is to implement Professor Sunderland's brilliant primer on judicial councils by a more specific presentation utilizing the experiences of the New York State Judicial Council. Of the three elements that enter into a consideration of the judicial branch of government, the first—the substantive law, the law of rights and duties—is not within the province of the judicial council either in New York or elsewhere. The second element—the machinery of justice—is the principal field of the judicial council. If the council does its work well in that field, attention cannot fail to be focused upon the third and most important element—also part of a judicial council's problems—the judicial personnel.

This article places the British material on religion and social policy in a comparative perspective. In order to do so, it introduces a recently completed project on welfare and religion in eight European societies, entitled ‘Welfare and Religion in a European Perspective’. Theoretically it draws on the work of two key thinkers: Gøsta Esping-Andersen and David Martin. The third section elaborates the argument: all West European societies are faced with the same dilemmas regarding the provision of welfare and all of them are considering alternatives to the state for the effective delivery of services. These alternatives include the churches.

ASOCIAL “WE” The problems discussed in the book are revealed by the well-known view of Aristotle that man is a cultural, social and political being: ...And he who by nature and not by mere accident lives outside the state, is either a wretch or superhuman being; he is ‘without lineage, law, hearth,‘ as denoted by Homer, because if someone is such a person by nature, he desires passionately war, being isolated, as a stone excluded from dice. Furthermore, It appears that the state is a creation of nature and most of all concerns the individual because when each person separately is not self-sufficient, he will be placed in the same relation to the state like these and other parts in relation to a whole. However, one who is unable to live in the community, or does not need it at all, being self-sufficient, such a person is not a member of the state, so he must be either a beast or god. Directed by the spirit of contrariness, I will add Friedrich Nietzsche’s comment : “Aristotle says that in order to live alone one must be either an animal or a god. The third alternative is lacking. A man must be both – a philosopher.”

We describe a new species of dull-colored flea-toad, genus Brachycephalus, from the Atlantic Forest of Caparaó mountains in southeastern Brazil. The new species is characterized by its diminutive size, “leptodactyliform” body, brownish color with an inverted V-shaped dark mark on dorsum, skin smooth, hyperossification and dorsal shield absent, linea masculinea absent, Fingers I and IV vestigial, Toe I externally absent, Toe II reduced but functional, Toes III and IV with pointed tips, Toe V vestigial, and ventral color uniformly brown. It is a leaf litter dweller, known only from type locality in the humid forests on the eastern slopes of Parque Nacional do Caparaó mountains, a protected area in the states of Espírito Santo and Minas Gerais, southeastern Brazil. It is the third flea-toad occurring in the state of Espírito Santo recovered as sister to all other Brachycephalus distributed from the state of São Paulo northward in the Atlantic Forest.
