Abstract:

This investigation constitutes an attempt towards(1) understanding issues and problems relating to the notions of one, many, part and whole in Parmenides and Plato; (2) extracting conditions for a successful account of multiplicity and parthood;(3) surveying Deleuzian conceptions and uses of these notions; (4) appraising the extent to which Deleuze’s metaphysics can answer some of these ancient problems concerning the status of multiplicity and the nature of mereological composition, that is, of the relations that pertain between parts and the wholes that they compose.

Abstract:

Hench developed the first bioactive material, Bioglass®, based on a soda-lime phospho-silicate glass. Most materials, elicit a neutral response when implanted into the human body. Bioglass®, however, was seen to create a positive response by depositing the body’s natural bone substance, Hydroxyapatite on its surface. Although it is recognised that compositional modifications effect bioactivity, there is very little comprehension of the composition-structureproperty relationships that result in such bioactivity. The objective of this investigation, therefore, was to study such fundamental relat

Abstract:

This study analyzes the composition and structure of the Jordanian bourgeoisie over the period 1967-1989. Both the study of the structure and composition of the social classes and their role in the political and social change are neglected topics when Jordan is concerned. On this basis, the main argument of this thesis is that the bourgeoisie is an important social class, whose study andanalysis can yield a better understanding of socio-economic structure and change inJordan. This study uses the Marxist paradigm as a theoretical framework to define the bourgeoisie as the social class that has

Abstract:

This research focuses on how capitalising on community pattern, a character of ecological communities, could improve the predictability of community models, thus facilitating research in conservation. Patterns of communities not only depict phenomena but are also useful for predicting potential changes in species composition when patterns are governed by specific mechanisms. Most conventional prediction models do not take community pattern into consideration, despite the fact that incorporating community patterns into conventional models for predicting species richness and composition may enha

Two different data sources are combined to build up a three-dimensional picture of Jupiter's troposphere. The first dataset is from the Cassini VIMS instrument, and was taken during the 2000-2001 J

C-S-H morphology affects the shape of the capillary pores, as the capillary porosity is defined by the outer product C-S-H. Thus, the morphology of C-S-H partially determines transport properties and the durability of cementitious materials. This underlines the importance of u

A recurring theme in biology is the aggregation of mRNA-protein complexes (mRNPs) into higher order assemblies. Often these complexes play important roles in the regulation of gene expression, but the function of the conserved cytoplasmic mRNP assemblies - P bodies and stress granules, is not known. It is believed that the misregulation of granule assembly is related to disorders like Amyotrophic Lateral Sclerosis and Frontotemporal Lobe Degeneration. Determining the complete composition of these granules may hold the key to understanding the function and mechanism of assembly of these granule
