Research Acad. I.P. Pavlov, concerning the study of the functions of the higher parts of the central nervous system, the general results of which are summed up by his recently published book "Twenty Years of Objective Study of the Higher Nervous Activity of Animals," belong to rare and exceptional events in the history of science, area, a strong stream suddenly appears, saturated with the dynamics of a new methodology, a large and sharply outlined boundary is immediately erected, denoting a new era here, and the further development of this area along a new path is predetermined, constantly, as it moves, opening up new and new perspectives and enlivening the work of further by asking questions.

The last few years have inaugurated a new era in the history of the South African diamond deposits, inasmuch as rich bodies of diamantiferous ground have been located at great distances from localities which have previously been worked successfully. The group of which the Premier Mine is the best known member is the most striking example of this extension of area, but the centre of gravity of the diamond-mining industry seems to be gradually shifting northward, and the opening up of the interesting deposit of the Somabula Forest, so far north of any other known occurrence, foreshadows the development of an important branch of the industry in the Cinderella of the South African provinces, as Rhodesia has been not inaptly termed.

Currently, the ongoing paradigm change requires both opening up the main provisions formulated by T. Kuhn and their further development. The article formulates the signs of scientific revolutions and the necessary conditions for their implementation. The history of the new paradigm is given and the periodicity in its emergence is revealed. A conclusion is made about the need to create a new research direction - Parametry. Areas of research are indicated, which scientific results will lead to new scientific revolutions in the foreseeable future.

The aim of the research is a retrospective analysis of the history and stages of development of digital land reclamation in Russia, the definition of «Digital land reclamation» and trends in its further development. In the framework of the retrospective analysis the main stages of melioration formation are determined. To achieve the maximum effect of the «digital reclamation» requires full cooperation of practical experience and scientific potential accumulated throughout the history of the reclamation complex, and the latest achievements of science and technology, which is currently possible only through the full digitalization of reclamation activities. The introduction of «digital reclamation» will achieve greater potential and effect in the modernization of the reclamation industry in the «hightech industry», through the use of innovative developments and optimal management decisions.

It is generally assumed that The Vampyre was published against John Polidori's will. This article brings evidence to support that he played, in fact, an active role in the publication of his tale, perhaps as a response to Frankenstein. In particular, by making use of the tools of textual criticism, it demonstrates how the ‘Extract of a Letter from Geneva’ accompanying The Vampyre in The New Monthly Magazine and in volume editions could not be written without having access to Polidori's Diary. Furthermore, it hypothesizes that the composition of The Vampyre, traditionally located in Geneva in the course of summer 1816, can be postdated to 1818, opening up new possibilities for reading the tale in the context of the relationship between Polidori, Byron, and the Shelleys.

Background: Meningeal melanocytoma is a rare benign tumor, most frequently located in the posterior fossa and spinal canal. Our objective is to illustrate a case of this tumor that originated in the thoracolumbar area of the spine and had an uneventful clinical course after total resection. Case description: We present the case of a 59 years old woman who presented with a medical history of ongoing neurological deterioration due to spastic paresis of the lower extremities. MRI of the thoracolumbar region identified a melanocytic melanoma as the underlying cause. Conclusions: Melanocytic tumors of the central nervous system have a typical appearance on MRI scans, varying with the content and distribution of melanin. However, the differential diagnosis between malignant melanoma and melanocytoma still depends on pathological criteria. Spinal meningeal melanocytoma has a benign course, and it is amenable for gross total resection. The outcome is favorable following complete resection.

The profound changes within the Albanian society, including Albania, Kosovo and Macedonia, before and after they proclaimed independence (in exception of Albania), with the establishment of the parliamentary system resulted in mass spread social negative consequences such as crime, drugs, prostitution, child beggars on the street etc. As a result of these occurred circumstances emerged a substantial need for changes within the legal system in order to meet and achieve the European standards or behaviors and the need for adoption of many laws imported from abroad, but without actually reading the factual situation of the psycho-economic position of the citizens and the consequences of the peoples’ occupations without proper compensation, as a remedy for the victims of war or peace in these countries. The sad truth is that the perpetrators not only weren’t sanctioned, but these regions remained an untouched haven for further development of criminal activities, be it from the public state officials through property privatization or in the private field. The organized crime groups, almost in all cases, are perceived by the human mind as “Mafia” and it is a fact that this cannot be denied easily. The widely spread term “Mafia” is mostly known around the world to define criminal organizations.The Balkan Peninsula is highly involved in these illegal groups of organized crime whose practice of criminal activities is largely extended through the Balkan countries such as Kosovo, Albania, Macedonia, Serbia, Bosnia, Croatia, Montenegro, etc. Many factors contributed to these strategic countries to be part of these types of activities. In general, some of the countries have been affected more specifically, but in all of the abovementioned countries organized crime has affected all areas of life, leaving a black mark in the history of these states.

Studying the current state of cartography and ways of further developing the industry, the role of the map in the future of the society, new methods of promoting cartographic products is impossible without a deep scientific analyzing all the paths, events and factors influencing its formation and development throughout all the historic steps of cartographic production in Russia. In the article, the history of cartographic production in Russia is considered together with the development of private, state and military cartography, since, despite some differences, they have a common technical, technological and production basis. The author describes the stages of originating, formation and growth of industrial cartographic production from the beginning of the XVIII century until now. The connection between the change of political formations and technological structures with the mentioned stages of maps and atlases production is considered. Each stage is studied in detail, a step-by-step analysis was carried out, and the characteristics of each stage are described. All the events and facts are given in chronological order, highlighting especially significant moments influencing the evolution of cartographic production. The data on the volumes of printing and sales of atlases and maps by commercial and state enterprises are presented. The main trends and lines of further development of cartographic production in Russia are studied.
