islamic architecture has been a great influence on different parts of the world, even so there are some similar factors, but the aspect of culture will make the polarization between them. upon the vast spread that muslims had in the 7th century (a.d.) islamic culture and belief moved in different continents from the fareast parts of asia to the west of the mediterranean. at the beginning islam ...

This paper explains the procedure and results of an experiment on the relationship between the unconfined compressive strength and percent weight loss due to freeze and thaw durability test of laboratory compacted soil-cement specimens. The tests were carried out on soil cement mixtures of 10 different soil types. It was shown that the percent weight loss due to freeze and thaw durability test ...

This paper reports combined hydrophobicity and mechanical durability through the nanoscale engineering of surfaces in the form of nanorod-polymer composites. Specifically, the hydrophobicity derives from nanoscale features of mechanically hard ZnO nanorods and the mechanical durability derives from the composite structure of a hard ZnO nanorod core and soft polymer shell. Experimental character...

Zero transvalvular pressure fixation is thought to improve porcine bioprosthetic heart valve (BHV) durability by preserving the collagen fiber architecture of the native tissue, and thereby native mechanical properties. However, it is not known if the native mechanical properties are stable during long-term valve operation and thus provide additional durability. To address this question, we exa...

As defined in BS EN 350-1 [1], natural durability is ‘the inherent resistance of wood to attack by wood destroying organisms’. Eaton and Hale [2] defined natural durability or decay resistance as the ability of the Heartwood of any wood species to resist decay. Normally, natural durability is measured by exposing the wood to biological agents such as termites, beetles, fungi and marine borers (...

This paper outlines the process of design and prototyping of a modular housing system aimed at serving the needs of people in the Pacific island nations. Many people in these islands are economically challenged and live in sub-standard housing at low elevations, making them vulnerable to increased tropical storms brought about by climate change. A collaborative team comprised of architecture an...

in ziegler-natta olefin polymerization, the pore architecture of catalysts plays a crucial role in catalyticperformances and polymer properties. while the type of preparation routes (such as chemical reaction andsolution precipitation) greatly affects the catalyst pore architecture as a result of different solidification mechanisms,the modification of the pore architecture within a given route ...

in this paper, an exchange of letters between the philosopher jacques derrida and architect peter eisenman is used as a catalyst to discuss the material qualities of glass and its relationship with the concept of transparency in architecture. in his criticism of an architecture devoid of human qualities, derrida uses glass, defined through walter benjamin’s writings, as a hard and cold material...

This paper presents a fuzzy-logic-based methodology of life extending control (LEC) for robust wide-range operation of fossil power plants including load-following, scheduled shutdown, and hot startup. The objectives of the LEC are performance enhancement and structural durability of both aging and new fossil power plants. The proposed control system has a two-tier architecture, which explores ...
