Resumen: Desde los años setenta del pasado siglo se viene empleando con éxito en todo el mundo una metodología de análisis preliminar de estabilidad de huecos subterráneos basada en el uso de las clasificaciones geomecánicas, siendo las más empleadas el RMR de Bieniawski y el índice Q de Barton. Esta última es la que se empleará en este estudio. Se trata de una aproximación empírica que permite estimar, mediante la asignación de una puntuación, la calidad del macizo rocoso, con el objetivo de conocer su grado de estabilidad ante la ejecución de una excavación subterránea. En la presente investigación se aplica el índice Q al estudio de la estabilidad de galerías y filones de una pequeña mina de oro en el Cantón de Ponce Enríquez, Ecuador. En este trabajo se propone un nuevo gráfico empírico tomando para ello otros anteriores y los resultados de la evaluación de tal manera que pueda determinarse el factor de seguridad y el máximo vano estable que pueda abrirse en minas de este tipo. Una de las principales aportaciones del trabajo es la de validar el índice de Barton a huecos pequeños.Palabras clave: Índice Q, minería artesanal, mina subterránea, máximo vano, oro.Abstract: Rock mass classifications are used throughout the world since the 1970’s. It is a methodology for the prefeasibility assessment of the stability of underground openings. The most used are the Bieniawski’s RMR and the Barton’s Q index. The latter is the one we have used in this study. It is an empirical approach that gives a numerical score to the rock mass quality to determine the degree of stability or reinforcement required. In this research, the Q index is applied to assess the stability of galleries and veins in a small gold mine in Canton Ponce Enriquez, Ecuador. A new empirical chart has been established using previous ones and considering the results of the study. This chart can be used to determine the safety factor and stable maximum span that can be opened in vein-mines of this type. One of the main contributions of the work is to validate the Barton index to small holes.Keywords: Q index, artisanal mining, underground mine, maximum span, gold.

The Mind

The inner-outer dualism, with its associated conception that the mind is a reality isolated from the world, permeates our everyday thinking. This article begins by demonstrating from the philosophy of the twentieth century the unreality of this separation and the stability of internal constructions. Once we isolate the mind in our imagination, we feel authorized to dream of magical shortcuts to overcome the isolation, such as telepathy or, in the psychotic, transparency or the sounding of thoughts, the theft of ideas, the imposition of ideas from the external world. We are not minds, permanent or eternal, inserted in a world that we see passing around us; we are temporary beings. The self is a representation, an internalized metaphor that we turn into a stable but fragile metaphor in the face of a changing reality, which endows us with immortality and consoles us. The psychotic is the one who lives the split because he has not been able to handle the conventionality of that double language, and accept that reality is at the same time fixed and changing, for this reason they need to adhere to permanent objects, with the quality of stable things. The psychotic is the one who believes in the official language at face value, is sick of conventions. If everyone knows the patient's thoughts, in some way this means that the thoughts are not locked in the head, an idea contrary to cultural belief, which produces terror because it is experienced as unnatural, cancels the division of interior and exterior, which means the experience of loss of identity and agency, the lost of control. Delirium is developed as a way of clinging to reality in the face of extreme disavowal of one's perceptions or feelings.

This paper presents the case of psychology from a perspective not widely recognized by the West, namely, the Egyptian, Arab, and Islamic perspective. It discusses the introduction and development of psychology in this part of the world. Whenever such efforts are evaluated, six problems become apparent: (1) the one-way interaction with Western psychology; (2) the intellectual dependency; (3) the remote relationship with national heritage; (4) its irrelevance to cultural and social realities; (5) the inhibition of creativity; and (6) the loss of professional identity. Nevertheless, some major achievements are emphasized, and a four-facet look into the 21st century is proposed.

SummaryIn 4 collaborative trials, involving a varying number of hospital laboratories in the Stockholm area, the coagulation activity of different test materials was estimated with the one-stage prothrombin tests routinely used in the laboratories, viz. Normotest, Simplastin-A and Thrombotest. The test materials included different batches of a lyophilized reference plasma, deep-frozen specimens of diluted and undiluted normal plasmas, and fresh and deep-frozen specimens from patients on long-term oral anticoagulant therapy.Although a close relationship was found between different methods, Simplastin-A gave consistently lower values than Normotest, the difference being proportional to the estimated activity. The discrepancy was of about the same magnitude on all the test materials, and was probably due to a divergence between the manufacturers’ procedures used to set “normal percentage activity”, as well as to a varying ratio of measured activity to plasma concentration. The extent of discrepancy may vary with the batch-to-batch variation of thromboplastin reagents.The close agreement between results obtained on different test materials suggests that the investigated reference plasma could be used to calibrate the examined thromboplastin reagents, and to compare the degree of hypocoagulability estimated by the examined PIVKA-insensitive thromboplastin reagents.The assigned coagulation activity of different batches of the reference plasma agreed closely with experimentally obtained values. The stability of supplied batches was satisfactory as judged from the reproducibility of repeated measurements. The variability of test procedures was approximately the same on different test materials.

The Voice

There are two most inevitable issues on national literature, in this case Indonesian literature. First is the translation and the second is the standard of world literature. Can one speak for the other as a representative? Why is this representation matter? Does translation embody the voice of the represented? Without translation Indonesian literature cannot gain its recognition in world literature, yet, translation conveys the voice of other. In the case of production, publication, or distribution of Indonesian Literature to the world, translation works can be very beneficial. The position of Indonesian literature is as a part of world literature. The concept that the Western world should be the one who represent the subaltern can be overcome as long as the subaltern performs as the active speaker. If the subaltern remains silent then it means it allows the “representation” by the Western.

Abstract The quest for urgent solution to resolve the world liquidity problem has continued to generate enthusiastic debates among political economists, policy makers and the academia. The argument has focused on whether the World Bank Group was established to enhance the stability of international financial system or meant to enrich the developed nations. This study argues that the existing political interest of the World Bank Group in Africa may serve as lesson learned to other ambitious African Monetary Union.

<p></p><p>Interfacial metal-oxide systems with ultrathin oxide layers are of high interest for their use in catalysis. In this study, we present a density functional theory (DFT) investigation of the structure of ultrathin rutile layers (one and two TiO<sub>2</sub> layers) supported on TiN and the stability of water on these interfacial structures. The rutile layers are stabilized on the TiN surface through the formation of interfacial Ti–O bonds. Charge transfer from the TiN substrate leads to the formation of reduced Ti<sup>3+</sup> cations in TiO<sub>2.</sub> The structure of the one-layer oxide slab is strongly distorted at the interface, while the thicker TiO<sub>2</sub> layer preserves the rutile structure. The energy cost for the formation of a single O vacancy in the one-layer oxide slab is only 0.5 eV with respect to the ideal interface. For the two-layer oxide slab, the introduction of several vacancies in an already non-stoichiometric system becomes progressively more favourable, which indicates the stability of the highly non-stoichiometric interfaces. Isolated water molecules dissociate when adsorbed at the TiO<sub>2</sub> layers. At higher coverages the preference is for molecular water adsorption. Our ab initio thermodynamics calculations show the fully water covered stoichiometric models as the most stable structure at typical ambient conditions. Interfacial models with multiple vacancies are most stable at low (reducing) oxygen chemical potential values. A water monolayer adsorbs dissociatively on the highly distorted 2-layer TiO<sub>1.75</sub>-TiN interface, where the Ti<sup>3+</sup> states lying above the top of the valence band contribute to a significant reduction of the energy gap compared to the stoichiometric TiO<sub>2</sub>-TiN model. Our results provide a guide for the design of novel interfacial systems containing ultrathin TiO<sub>2</sub> with potential application as photocatalytic water splitting devices.</p><p></p>

UDC 336.74   Vasylenko Artur, post-graduate student. Mariupol State University. Cryptocurrency Phenomenon in the International Monetary System. The main prerequisites of cryptocurrency emergence in the international monetary system in terms of regionalization of the world economy are defined in the article. Determination of «cryptocurrency» category was analysed from the point of two main approaches to its treatment: on the one hand cryptocurrency is admitted to be the currency equally to the sovereign currency, and on the other hand it is considered as an unrecognized virtual asset. The main consequences which arise in case of widespread use of crypto currency for the country and for the parties that agreed to use cryptocurrency were analysed and systematized. On the basis of the research, given the current trends in the world economy, the author put forward and substantiated the hypothesis to classify the phenomenon of cryptocurrency as the effects of a famous philosophical «Negation of negation law» formulated by G. Hegel at the beginning of the XIX century.   Keywords: cryptocurrency, material money, electronic money, digital currency, regional currency integration, blockchain, mining, capitalization, «Negation of negation law».

The paper provides the framework for embracing multiculturalism as a source of national identity, a political ‘profession de foi’, and an engine for a government to gain positive outcomes, leading to better immigrant integration and economic advantages for any country in the world. Noteworthy, Canadian federal policy of multiculturalism, since its official adoption in 1971, is witnessed to work stunningly and in contrast to developments elsewhere – in Canada, public support for multiculturalism is seeing unprecedented growth. Currently, the diversity of the Canadian populace is increasing faster than at any time in its history; Canada’s ethnic makeup has notably altered over the time due to changing immigration patterns. According to the latest poll findings, 84% of Canadians agree with the statement that ‘Canada’s multicultural makeup is one of the best things about this country’; 61% of Canadians believe multiculturalism ‘strengthens national identity’. Moreover, released data from Environics reveals that 27% of Canadians believe ‘multiculturalism is the one characteristic about Canada that most deserves to be celebrated on its upcoming 150thanniversary. Undeniably, people around the world tend to view Canada as “good”. Importantly, the election of Justin Trudeau is viewed as an excellent opportunity to invigorate brand Canada. Noteworthy, brand Justin Trudeau is currently composed of his belief in and promotion of the values of tolerance, equality and diversity. While recognizing the value for society of the human dignity inherent in each individual, Trudeau’s government aims to push beyond mere tolerance to mutual understanding and respect.
