Fluidised hot melt granulation (FHMG) is a novel technology for granulation process in pharmaceutical industry, which has distinct advantages over other commercial techniques. The aim of this research was to investigate granulation and the effect of process parameters that may affect FHMG process. In this work, ballotini beads were used as the model particles and Lutrol (R) F 68 Poloxamer 188 was used as meltable solid binder. In order to determine the granulation and nucleation mechanism in this co-melt FHMG system, several parameters were investigated, such as binder content, particle size of binder and particle size and hydrophobicity of ballotini. These parameters were correlated to granule size distribution, mean granule size and granule shape. Furthermore, these experimental investigations were designed so that the coalescence model could be applied to the co-melt FHMG system. The analysis indicated that the non-inertial regime extends over a relatively short time period of

Sociological assertions of religious vitality in Euro-American societies have developed a paradigm of spirituality in which, following earlier studies of the New Age, a distinction is drawn between external authority and self-authority. Methodologically and theoretically problematic, this paradigm diverts attention from people’s social practices and interactions, especially in relation to multiple religious authorities. Drawing upon ethnographic fieldwork with an English religious network, and building upon the work of Pierre Bourdieu, this paper considers situations in which multiple authorities tend to relativize each other. Conceptualizing this in terms of nonformativeness - the lack of authorities’ abilities formatively to shape religious identity, habitus, and competition over religious capital - a new understanding of individual secularization emerges that questions assertions of vitality.
