Opis:
La fable du Bilboquet de Marivaux donne à imaginer la fureur sociale provoquée par ce jeu à l’époque. Poussé par un ressentiment contre le bilboquet qui distrait sa maîtresse, le narrateur développe comment la Folie a conquis les gens de l’Europe à travers cette frivolité. À travers la mise en scène de la contagion du jeu, on observe comment le plaisir qu’il procure ainsi que le désir mimétique des hommes contribuent au succès du bilboquet. Le désordre social résultant de cette frénésie ludique nous amène à nous interroger sur la nature du jeu : s’agit-il simplement d’une distraction divertissante ou représente-t-il en réalité un danger ? Une telle « bagatelle » peut avoir de graves conséquences, conformément à une logique de réévaluation du « rien » que l’on retrouve dans la plupart des œuvres de Marivaux.
The “Le Bilboquet” of Marivaux illustrates the social frenzy incited by this game at that time. Driven by resentment against the bilboquet, which distracts his mistress, the narrator elaborates on how Madness has conquered the people of Europe through this frivolity. Through the depiction of the contagion of the game, we could observe how the pleasure it brings and the mimetic desire of men contribute to the success of the bilboquet. The social disorder resulting from this ludic frenzy leads us to question the nature of the game: is it merely an entertainment or does it actually represent a danger? Such a trifle could have grave consequences, in line with the logic of reevaluating the “nothingness” that we can find in most of Marivaux’s works.

Opis:
For centuries, women have been victims of social prejudices and discrimination. Literature reveals various ways women have worked to breakthrough from the point(s) where men have relegated them. Their movements are seen as feminist movement. Merging feminism with Christianity, Christian feminism would mean an aspect of feminist theology which seeks to advance and understand the equality of men and women morally, socially, spiritually, and in leadership from a Christian perspective. A few of the 21st century women in Nigeria are seen to be a bit open in terms of sexuality; we see nursing mothers going out to work; women engaged in new industries and professions, and the acceptance that women will work outside the home, have children outside marriage, as well as the right to control their own sexuality. Despite these accomplishments by women, they are still prone to more problems, basically in the Church. Most persons in the Christian religion do not feel that feminism should come in or be exercised by Christian women. From their view of the feminist’s approach to life, these Christians see feminism to preach a woman’s right to have abortion, practice lesbianism as well as marry, be free from traditional roles, and even reject God as the ultimate authority. This is absolutely untrue. Based on the above premise, this paper tried to justify the reason why Christianity as well as the Church desperately needs feminism. The descriptive and the comparative phenomenological methodology were utilised in this paper, with the advantage data so collected to speak for themselves.

Opis:
Sidonie-Gabrielle Colette played a significant role in the development of French literature. Her novels vividly depict independent and self-aware women, thereby reflecting the author herself. Colette's works have captured the attention of researchers and have been the subject of numerous studies. In this proposed research, an interdisciplinary approach combining literary and linguistic perspectives is adopted to explore Colette's literature. The objective of this study is to closely examine the portrayal and circumstances of women and girls in Colette's work, specifically focusing on the nomino-adjectival collocations involving the lexemes femme and fille used by the author in her six novels from the “Claudine” series. These novels serve as prime examples of Colette's reclamation of autonomy through her writing. The research will culminate in a literary analysis, contrasting the results obtained through the linguistic methodology with the insights gained from a literary approach.

Opis:
Flotation tests with intergrown particle liberation were conducted to explore a separation method of difficult-to-separate coking coal from the Tangshan Kailuan mine in China. The particle size distribution, density and coal petrography were investigated. The difficult-to-separate coking coal sample resulted in intergrown particles, such as non-liberated coal and rocks. Thus, intergrown coal particle liberation and re-separation tests were conducted. The results showed that grinding time had a great effect on the flotation performance. Grinding prompted coal to dissociate and improve the surface hydrophobic properties of minerals. However, heterogeneous fine silt covered the surface of coal particles when coal was ground too long. The inorganic mineral particles were over-ground and reduced the contact angle of coal. The results of coal rock dissociation and laboratory re-separation tests showed that clean coal combustible recovery increased through intergrown particle liberation and re-separation.

The article concerns the interrelation between the three soteriological categories: salvation, liberation and healing, in order to better highlight their characteristics and, above all, to show their complementarity. After discussing the initial issues related to etymology and the contemporary spiritual, religious and social context, salvation is presented in the light of the three phenomena present in today’s piety: fatalism, dolorism, and demonism that distort its proper meaning. Then salvation was shown in the perspective of human aspirations for liberation: first in historical approach, bringing out the difficulties what kind of relationship he encountered, especially in the last three centuries, and in the second part – in the theological approach, which the center is the work of Christ, realized in the Holy Spirit. It was supplemented in the last part of the article, where it was proved that liberation and healing always indicate the fullness of salvation of the human being.

Opis:
Rehabilitacja teologii wyzwolenia stała się obecnie możliwa dzięki wytężonej pracy kilku teologów, a w szczególności: Gustavo Gutiérreza – jednego z ojców teologii wyzwolenia w Ameryce Łacińskiej i kardynała Gerharda Ludwiga Müllera – dziś prefekta Kongregacji Nauki Wiary. Impulsem do tych działań mogło być w porę zauważone przez Josepha Ratzingera w instrukcji Libertatis conscientia zaniepokojenie spowodowane traktowaniem przez teologię wyzwolenia ubóstwa tylko w wymiarze materialnym. Gutiérrez i Müller uważają jednak, że ubóstwo jest symbolem wszelkich ograniczeń bytu, a w życiu społecznym uwidacznia to najbardziej ubóstwo materialne i socjalne. Dla teologii wyzwolenia bardzo palącym punktem wyjścia jest więc ubóstwo materialne, ale ubóstwo rozciąga się w efekcie na całość przygodnej egzystencji ludzkiej. „Ubogi” z istoty swej woła do Boga, a Bóg w Starym i Nowym Testamencie szczególnie troszczy się o „ubogiego”. Tak egzystencja ludzka – jako kontyngentna – jest uboga, a więc dotyczy wszystkich, nie tylko materialnie ubogich, lecz również i bogatych. Stąd każdy człowiek potrzebuje wyzwolenia z tej nędzy moralnej, zła, grzechu i śmierci. W ten sposób teologia wyzwolenia nadaje teologii klasycznej realność i właściwe rozumienie wolności, która ma swe źródło jedynie w Bogu. Jezus Chrystus, wcielony Bóg, jest Boskim Wyzwolicielem z nędzy egzystencjalnej każdego człowieka.
Liberation Theology, which began in Latin America in the 1960s, faced constant opposition and objections on the part of classical theology. It has been constantly accused of secularizing and sociologizing the main Christian religious concepts - salvation, freedom and Church, in particular. This is why, in 1984 and 1986, Cardinal Joseph Ratzinger, Prefect of the Congregation for the Doctrine of the Faith, issued the Instruction Libertatis nuntius and Libertatis conscientia. The movement lost its status and developmental impetus, finding itself under sharp criticism of Rome. Nevertheless, thanks to the long-term fruitful cooperation of Professor Gerhard Ludwig Müller, who later became a bishop and a cardinal, with Gutiérrez and other liberation theologians as well as with the Latin American episcopates, the basic conceptual network for Liberation Theology has been developed. It emphasizes classical, universal and evangelical aspects of Liberation Theology to prove that it enriches classical theology with its qualities of social realism, praxeological outlook and its historical and sociological dynamism. As a result, Liberation Theology, whose main objective is to make Gospel real and active in this life rather than in its abstract manifestation alone, seems to be more and more openly accepted as legitimate on behalf of the Vatican and Pope Francis. In this way, it can undergo its revalidation and a second chance for growth.

Opis:
The use of centrifugal gravity concentration in the closed-grinding circuit of a gold-containing massive sulphide ore was tested on classifier underflow and overflow. A continuous Knelson CVD6 was retrofitted to the hydrocyclone underflow for recovery of Au and Pb at a coarser feed size. The objective of treatment of overflow was recovering unliberated Au prior to flotation. The tests were performed in actual operating conditions at Nyrstar’s Myra Falls Mine. The results of the tests on the cyclone underflow revealed that both liberated and unliberated Au and Pb were recovered by the Centrifugal Variable Discharge (CVD) concentrator. Concentrate grades <60g/Mg Au were attainable at a more than 20% recovery. This application also allowed early and increased Pb recovery before it became gravity unrecoverable by over-grinding. Other benefits included capturing middlings for regrinding as well as potential coarser grinding and increase in mill throughput. A coarse grind also corresponds to a reduction in deformation of Au-particles, and is beneficial for increased Au recovery in downstream processing. Treatment of cyclone overflow by the CVD also provided favourable results. The outcomes included capturing unliberated gold prior to flotation and potentially reducing pumping requirements and reagent consumption. A comparison of the metallurgical performances showed that CVD application on classifier underflow was more effective. The CVD was capable of recovering unliberated gold in sulphides and performed better at a coarser particle size. Therefore, when used with the grinding circuit, a coarser grind can be applied and the CVD could be used to reject gangue at a coarser size.

The paper analyses one of the Gellu Naum’s poetic masterpieces, Vasco da Gama. The main aim is to reconstruct Naum’s aesthetic premises that lead him to transform the images to reveal the real nature of the poetic objects. The theoretical background for Naum is created by the André Breton’s essay Crise l’objet (1936). The article presents the crucial imperative in the Romanian Surrealism leader’s Nuca terorizează orasele. Eliberarea obiectului suprarealist în Vasco da Gama de Gellu Naum 219 appeal, the object to be stripped of cretinizing uniforms and liberated by removing from the quotidian context. Rather than an inert object engulfed by the perceiving consciousness, the liberated thing becomes active and devours its observer. The language of permanent and fluid transformations accompanies a promiscuous, perpetual orgy of devouring. The concept of “liberation” is claimed as both “emancipation” and “release”. Disfunctional objects gain a new identity, being anthropomorfized or animated. Vasco da Gama propose a special type of sensibility reclined on an unruly imagination and encourages the reader to discover new relations between the object and the word.

Opis:
This study is an interdisciplinary examination of the relationship between religion and political liberation in an elite-arrested nation-state. The study is situated within the empirical context of the Nigerian socio-political system. The case-study state is accordingly, representative of others, currently under what the work denotes as domestic elite hegemony, which necessitates political liberation. Invariably, the study entails an elite theory analysis of the linkages between the research variables. Hence, a prognosis is occasioned by the analysis. The study finally found the possibility of a fusion of the two major religious persuasions in the country, in attempting to counterbalance the enduring and debilitating elite dominion of the Nigerian nation-state. The study is highly significant in its interdisciplinary methodology. Hence, it has succeeded in touching upon the subject areas of religion, sociology, political science and public administration. Consequently, the study possesses immense theoretical and empirical relevance.

Opis:
The article is a short analysis of the theological teaching of Joseph Ratzinger. It is focused on the idea of the Jesus’ Cross. The first part of the text considers a following subject: if Jesus were to be separated from His Cross, sooner or later such a theology would become a heresy. Such a heterodox consequence can be found in almost every Christological heresy. Cardinal Ratzinger dis-cusses this kind of thinking which he meets in liberation theology, i.e. an ideo-logical movement promoted by Gustavo Gutiérrez mainly in South America and Africa. The second part of the article is concentrated on the theology of liturgy, especially on that of the Eucharist. Joseph Ratzinger seeks to prove that the Eucharist is not a feast, a banquet, or a collective meal. The main sense of the Eucharist can only be found in the Cross where the Eucharist reveals its identity as a Holy Sacrifice of Jesus Christ the Victim-Priest. In the conclusion the au-thor claims that one cannot understand Jesus Christ without His Cross, because it is upon the foundation of the Cross that the Holy Faith of the Church, the creed of the Church, is built.

In recent years, the influence of different crushing systems (compression, impact, attrition) has been receiving more attention due to their significant role on particle liberation and shape of particles. The objective of this study was to investigate the effects of different crushing systems on both liberation degree and shape factors of chromite particles along with their enrichment conditions by shaking table. The tests were conducted on -1+0.5, -0.5+0.212 and -0.212 mm size fractions using the Wilfley type shaking table. The results of these tests showed that concentrates with higher metal contents were obtained by impact crushing of chromite in proportion to higher liberation degree and roundness of particles. Therefore, it was found that selective breakage can well be obtained by impact crushing in all fractions. The results of this study demonstrated the importance of crushing type on the liberation and enrichment processes.

The text also examines “official” forms of remembrance, such as museums and memorials, as well as popular narratives, myths and common tales surrounding the military operation, which are seen in the context of a specific collective identity of the population of the borderland. The article seeks correlations between professional research, political rhetoric and other aspects that created the “popular image” of the offensive. The question of regional memory is understood in the context of nationwide debates about contemporary history.

In the text offered to the reader I made an attempt to re-read the central claim presented in the work of S. de Beauvoir titled The Second Sex through the prism of lessons identified for modern upbringing. The central thesis can be described as follows: the differences between genders are socially and culturally conditioned, yet determined by belonging to biological sex; maternal instinct is culturally shaped; the mother’s attitude towards the child depends on its biological sex; housework is limiting women’s potential and focus on outlook causes fear of old age. The direction of change set by de Beauvoir is the androgynous upbringing of women, changing the model of marriage, conscious motherhood, women’s professional work, and creation of feminine cultural communities.

Opis:
A rougher flotation study has been done to analyze the effects of copper feed mineralogy, air flow rate and impeller radial velocity on metallurgical performance. During the performance testing the trials were exposed to metallurgical examining and computerised mineral analysis to establish a size-by-size mineralogy. The mineralogical and metallurgical information was compared to the material balance for rougher flotation results. These samples showed that copper recovery optimization should focus on the losses of liberated Cu-minerals and how they are associated with fine particles. The result of variable impeller radial velocity for each flotation cell cascade on metallurgical performance has been explored on a known-sized and an unknown-sized base, to gauge the input from the fine particles. An industrial application is discussed in this paper, and it validates that divergence of the impeller radial velocity and air flow has positive influence on the recovery.
W pracy przeprowadzono analizę wpływu składu mineralogicznego nadawy kierowanej do procesu flotacji głównej, wielkości przepływu dozowanego powietrza i prędkości obrotowej wirników na wyniki flotacji miedzi. Produkty procesu zostały poddane analizom chemicznym oraz mineralogicznym z wykorzystaniem systemu MLA. Przeprowadzone analizy wykazały, ze optymalizacja uzysku miedzi flotacji głównej w warunkach przemysłowych, limitowana jest obecnością w nadawie uwolnionych minerałów miedzi w skrajnych klasach ziarnowych. W artykule przedstawiono wyniki eksperymentów realizowanych w warunkach przemysłowych i pozytywny wpływ modyfikacji prędkości obrotowej wirników oraz stopnia napowietrzenia zawiesiny flotacyjnej na uzysk miedzi.
