Promising model range career excavators operating time assessment in real operating conditions
Authors: IVANOV Sergey , IVANOVA Polina , KUVSHINKIN Sergey 
Published: July 2020

The development prospects of the mining industry are closely related to the state and development of modern mining machinery and equipment that meet the technical and quality requirements of mining enterprises. Enterprises are focused on a quantitative assessment – the volume of mineral extraction, depending on the functioning efficiency of a promising series of mining machines, which include modern mining excavators. Downtime and unplanned shutdowns of mining excavators directly depend on the operating conditions of the mining machine, which has negative influence on the machine as a whole and its technical condition, which entails a decrease in the efficiency of using expensive mining equipment and economic losses of the mining enterprise.
The rationale for external factors that affect the operating time and technical condition of mining excavators is given. For a more detailed assessment of the influence of external influences on the efficiency of operation of mining machines, the influencing factors are divided into two groups: ergatic, directly related to human participation, and factors of a natural-technogenic nature, where human participation is minimized. It was revealed that factors of a natural-technogenic nature have the greatest influence. An algorithm is proposed for a comprehensive assessment of the technical condition and forecasting of operating time both in nominal and in real operating conditions, taking into account factors of a natural and technogenic nature.
It is proposed, based on the developed program for planning and evaluating the life of a mining excavator, to adjust the schedules for maintenance and repair (MOT and R) in order to minimize the number of unplanned downtime of a mining excavator and maintain it in good condition.
INDONESIAN ISLAMISM: THE WAR OF ISLAMIC LITERACY FROM MILLENNIALISM TO RADICALISM
Authors: Tambunan Elia 
Published: July 2020

This paper shows another dimension of the phenomenon of Islamism Indonesia. By doing the interpretation of a number of circumstantial historical Islam literacy with traces of the historical aspect as the research methodology, the authors found one important factor that gave birth to Islamism Indonesia is literacy not just ideology as believed by many scholars. The resulting literacy evolved in various forms of media, and thus generated by the Indonesia who settled in the Middle East, Islamic Indonesia elite, and ustad virtual at the estuary of the society in the war on Islam. This paper contributes to the efforts of Islamic Studies scholars from Indonesia to include literacy in Islamic Indonesia as part of the phenomenon of global Islamism manifestation in the development of the study of contemporary Islamist movements.

Miscelânea sobre a paz
Authors: Galtung Johan 
Published: July 2020

O texto colige três pequenos textos do pensador norueguês das relações internacionais Johan Galtung, que abordam seus recidivos temas da paz, da pesquisa sobre a paz e dos direitos humanos. O primeiro texto trata de uma homenagem pelos 20 anos da morte do estadista social-democrata alemão Willy Brandt (1913-1992), por cuja política para com o Leste Europeu no final dos anos 1960 (Ostpolitik), que levara à distensão com aqueles países, e futuramente à unificação alemã, recebera o prêmio Nobel da Paz em 1971. O segundo texto apresenta o projeto Hexágono TRANSCEND, cujo objetivo é estudar a geopolítica hexagonal contemporânea, considerando que os grandes polos geopolíticos do mundo atual seriam os EUA, a UE, a Rússia, a China, a Índia e a OMC, todos os quais possuidores de aspectos negativos e positivos, cujo estudo deverá se basear no método triádico diagnóstico-prognóstico-terapia. O terceiro texto foi escrito para o 6º Fórum Social, dedicado à discussão dos 10 artigos da Declaração das Nações Unidas sobre o Direito ao Desenvolvimento (1986), focado no tema dos direitos humanos. Abstract: This paper group three short texts wrote by the Norwegian international relations thinker Johan Galtung, who brought up the peace theme, researching peace and human rights. The first text is about a tribute to the 20th death anniversary of Willy Brandt (1913-1992), German social-democrat statesman, whose policy for the east Europe in the end of 60s (Ostopolitik), which brought dissention to east European countries, and, in time to come, the German unification, received the Nobel prize in 1971. The second text presents the hexagon project TRANSCEND, whose objective is study the contemporary hexagonal geopolitics, considering that the world's great geopolitics core would be USA, UE, Russia, China, India and the WTO, all bearers of positive and negative aspects, based on diagnoses-prognoses-therapy triadic method. The third text was written to the 6th Social Forum, meeting dedicated to discuss the 10 articles of the United Nations Declaration on the right to development (1986), focusing the human rights theme
História, Instituições e Rentismo: entraves ao desenvolvimento econômico venezuelano / History, institutions and rent-seeking: Venezuelan barriers to economic development
Authors: Lopes Ademil Lucio 
Published: July 2020

O presente artigo tem como objetivo apresentar e discutir os principais entraves enfrentados pela economia venezuelana em superar sua excessiva dependência em relação à renda petroleira. A partir de um enfoque histórico e institucional da sua economia, o artigo mostra que os arranjos institucionais construídos no país ao longo do tempo, essencialmente, incentivaram a lógica rentista dos atores sociais, de empresários a sindicatos. Esse legado institucional do país construído sobre a dependência do petróleo e a lógica rentista permaneceu no governo Chávez. Abstract: This paper aims to present and discuss the main obstacles faced by the Venezuelan economy to overcome its excessive dependence on oil revenues. From a historical and institutional focus of its economy, this article shows that institutionalarrangements built in the country over time essentially encouraged the rentier logic of social actors, from entrepreneurs to unions. This institutional legacy built on the country's dependence on oil and rentier logic remained on the Chavez government.
O genocídio em Ruanda e a inércia da comunidade internacional / Rwanda genocide and the inaction of the international community
Authors: Mendonça Marina Gusmão 
Published: July 2020

Entre abril e julho de 1994, o mundo assistiu impassível ao extermínio de mais de 800.000 pessoas em Ruanda. Tal morticínio é considerado o terceiro maior ocorrido desde 1950, comparável apenas àqueles verificados no Cambodja e em Bangladesh, na década de 1970. Entretanto, no caso de Ruanda, há um dado assustador: por ocasião da matança, a população do país era de aproximadamente 7.500.000 habitantes, sendo 6.300.000 hutus, 1.100.000 tutsis e 100.000 pigmeus. Isto significa que cerca de 11% dos ruandeses e ¾ da população tutsi foram eliminados em apenas um trimestre. A comunidade internacional nada fez para evitar a matança. Pelo contrário: além de não intervir diretamente, a Organização das Nações Unidas (ONU) reduziu drasticamente o contingente da força de paz que mantinha em Ruanda, a despeito das advertências do General Roméo Alain Dallaire, comandante das tropas da UNAMIR, de que a tragédia estava a caminho. Passado o estupor provocado pelo genocídio, restou o problema fundamental da reconstrução do país. A esse respeito, é preciso assinalar as precaríssimas condições econômicas da região, o que é agravado pelo estraçalhamento do tecido social durante a matança. Ademais, não podemos esquecer que, se em 1994, o mundo assistiu passivamente à dilaceração de Ruanda, agora poucos estão preocupados com as dificuldades de reconstrução de um lugar que não tem importância estratégica e não dispõe de grandes riquezas naturais.Os fatores que levaram ao genocídio em Ruanda e a inércia da comunidade internacional para impedir o massacre são os temas deste artigo. Between April and July 1994 the world seemed not affected by the extermination of more than 800.000 people in Rwanda. This is the third largest massacre since 1950 and can only be compared to those occurred in Cambodia and Bangladesh in the1970’s. But in the case of Rwanda there is something truly alarming: at the time of the genocide there were about 7.500.000 inhabitants in the country; 6.300.000 Hutus; 1.100.000 Tutsis; and 100.000 pigmies, what means that about 11% of Rwandans and ¾ of the Tutsi population were killed in a period of three months. The international community did nothing to avoid the massacre, and the United Nations (UN) even reduced its peacekeepers in Rwanda despite Roméo Alain Dallaire, the general commander of the UNAMIR troops in the country, having warned about the tragedy to come.In the aftermath of the world’s astonishment with the genocide the fundamental task is the problem of country’s reconstruction under very difficult economic conditions remained, now exacerbated by the social laceration it provoked. In addition, it cannot be forgotten that if in 1994 the world did nothing to avoid the massacre, nowadays there are still very few people worried about the reconstruction of a place poor in natural resources.The article analyses the conditions that conducted to Rwanda’s genocide and the inaction of the international community to avoid it.

Abstract
Extensive surveys with the Hubble Space Telescope over the past decade, targeting some of the most massive clusters in the sky, have uncovered dozens of galaxy cluster strong lenses. The massive cluster strong-lens scale is typically θ
E ∼ 10″ to ∼30″–35″, with only a handful of clusters known with Einstein radii θ
E ∼ 40″ or above (for z
source = 2, nominally). Here we report another very large cluster lens, RXC J0032.1+1808 (z = 0.3956), the second-richest cluster in the redMapper cluster catalog and the 85th most massive cluster in the Planck Sunyaev–Zel’dovich catalog. With our light-traces-mass and fully parametric approaches, we construct strong-lensing models based on 18 multiple images of five background galaxies newly identified in the Hubble data, mainly from the Reionization Lensing Cluster Survey (RELICS), in addition to a known sextuply imaged system in this cluster. Furthermore, we compare these models to Lenstool and GLAFIC models that were produced independently as part of the RELICS program. All models reveal a large effective Einstein radius of θ
E ≃ 40″ (z
source = 2), owing to the obvious concentration of substructures near the cluster center. Although RXC J0032.1+1808 has a very large critical area and high lensing strength, only three magnified high-redshift candidates are found within the field targeted by RELICS. Nevertheless, we expect many more high-redshift candidates will be seen in wider and deeper observations with Hubble or the James Webb Space Telescope. Finally, the comparison between several algorithms demonstrates that the total error budget is largely dominated by systematic uncertainties.

Abstract
We present a detailed abundance analysis of the three brightest member stars at the top of the giant branch of the ultrafaint dwarf (UFD) galaxy Grus II. All stars exhibit a higher than expected [Mg/Ca] ratio compared to metal-poor stars in other UFD galaxies and in the Milky Way (MW) halo. Nucleosynthesis in high-mass (

20 M
⊙) core-collapse supernovae has been shown to create this signature. The abundances of this small sample (three) stars suggests the chemical enrichment of Grus II could have occurred through substantial high-mass stellar evolution, and is consistent with the framework of a top-heavy initial mass function. However, with only three stars it cannot be ruled out that the abundance pattern is the result of a stochastic chemical enrichment at early times in the galaxy. The most metal-rich of the three stars also possesses a small enhancement in rapid neutron-capture (r-process) elements. The abundance pattern of the r-process elements in this star matches the scaled r-process pattern of the solar system and r-process enhanced stars in other dwarf galaxies and in the MW halo, hinting at a common origin for these elements across a range of environments. All current proposed astrophysical sites of r-process element production are associated with high-mass stars, thus the possible top-heavy initial mass function of Grus II would increase the likelihood of any of these events occurring. The time delay between the α and r-process element enrichment of the galaxy favors a neutron star merger as the origin of the r-process elements in Grus II.
Isotopic Evolution of the Inner Solar System Inferred from Molybdenum Isotopes in Meteorites

Published: July 2020

Abstract
The fundamentally different isotopic compositions of non-carbonaceous (NC) and carbonaceous (CC) meteorites reveal the presence of two distinct reservoirs in the solar protoplanetary disk that were likely separated by Jupiter. However, the extent of material exchange between these reservoirs, and how this affected the composition of the inner disk, are not known. Here we show that NC meteorites display broadly correlated isotopic variations for Mo, Ti, Cr, and Ni, indicating the addition of isotopically distinct material to the inner disk. The added material resembles bulk CC meteorites and Ca–Al-rich inclusions in terms of its enrichment in neutron-rich isotopes, but unlike the latter materials is also enriched in s-process nuclides. The comparison of the isotopic composition of NC meteorites with the accretion ages of their parent bodies reveals that the isotopic variations within the inner disk do not reflect a continuous compositional change through the addition of CC dust, indicating an efficient separation of the NC and CC reservoirs and limited exchange of material between the inner and outer disk. Instead, the isotopic variations among NC meteorites more likely record a rapidly changing composition of the disk during infall from the Sun’s parental molecular cloud, where each planetesimal locks the instant composition of the disk when it forms. A corollary of this model is that late-formed planetesimals in the inner disk predominantly accreted from secondary dust that was produced by collisions among pre-existing NC planetesimals.
Le chemin vers soi-même ou Le Scribe et son ombre.À propos de l’écriture aventurée d’Abdelkébir Khatibi
Authors: Hadji Khalid 
Published: July 2020

En réaction à la culture coloniale et au régime postcolonial, la littérature francophone au Maroc s’est articulée essentiellement autour de la question de l’identité où « soi » est nécessairement amené à se penser en fonction de l’autre. Dans cette perspective, en tant que penseur et qu’écrivain, Abdelkébir Khatibi apparaît comme figure centrale dont l’œuvre interroge en profondeur la problématique de l’altérité à travers les thématiques de l’origine, de l’étranger, de la bi-langue, du « je est un autre » appliqué à la culture, notamment dans le dernier livre Le Scribe et son ombre. La dimension interculturelle traverse l’œuvre de cet auteur en faisant de l’espace littéraire le lieu d’avènement de l’intersigne, ce qui favorise l’émergence d’une territorialité littéraire polyphonique et hybride qui tend vers l’universel.
La construction de l’identité féminine, entre héritage méditerranéen et quête émancipatoire dans trois œuvres romanesques contemporaines
Authors: Navarro Françoise 
Published: July 2020

Comment s’établit l’identité féminine en Méditerranée ? Les œuvres littéraires sont « un excellent terrain d’investigation pour qui veut observer les phénomènes identitaires »1. Car, comme pour les romans de Jeanne Benameur, de Carole Martinez et de Kaoutar Harchi, ils mettent en scène l’état de crise, l’état critique de « crise identitaire »2, ce bouleversement total de la perception de soi. La littérature montre également les opérations fondamentales du travail identitaire et met en évidence le processus de construction de l’identité féminine, qui passe par la quête de l’émancipation féminine.
