The paper presents the results of studies on quartzite milling in a ball mill. The milling was conducted in a batch system, for diversified compositions of balls. The milling product was subjected to granulometrical, morphological and strength analyses. On the basis of the developed Reid's theory and using the Austin-Gardner equation, a form of the function circumscribing the specific rate of comminution of selected size fractions was determined. The values of the breakage rate function bi, j for the mill's apparatus conditions were determined. The impact was investigated for a variable number of grinding media contact points on the values of specific rate S and the values of the breakage rate function bi, j. Furthermore, the values of coefficients occurring in the equations circumscribing the specific rate of milling S and breakage parameter bi, j were determined.
This paper intends to present an semantic and cultural analysis of Rabī‛ Jābir’s novel Druzes of Belgrade. Published in 2011, the story deals with a period in Slavic history of the 19th century that parallels the reality of Middle East in the same time. The aim of the contribution is to examine the narrative context of historical events in the hero’s life which are narrated primarily through the juxtaposition of historical facts. Distinctions that are made between the real and the imaginary in the novel are bound to mystify – perhaps even mask – the historical and cultural relationship between Arab and Slavs. The writer is not only involved in producing the story of the mutual Arab – Slavic (co)existence within the Ottoman empire in Lebanon and Balkan as well, but is equally intent on providing the story behind the (hi)story. As a mode of representing reality the analysed literary work isn’ t neutral; it presupposes system of moral values which underlies the Arab Christian hero’s factual statements connected with the powerstructure and power-relations of the Ottoman society the protagonist lives in. Between history and narrative literature exists a relationship of complementarity that can only enrich and deepen reader’s understanding of a given culture and society. The narrative representations of historical facts in the novel Druzes of Belgrade are semantic and philosophical operations and as such can be misrepresentations according to Rabī‛ Jābir’s literary tendency in a specific historical and intellectual setting.
