here, in situ synthesis of nano zinc oxide, along with aminolysis of polyester fabric, has simultaneously been carried out by using triethanol amine (tea) and zinc acetate. the zno nano particles (nps) were formed and stabilized on the fabric surface by amine compound at 130 °c for 1 h. the synthesis of nano zno particles on the polyester fabric were confirmed by x-ray diffraction (xrd) pattern...

in this paper, finite element model of woven fabric target has been investigated which is impacted by a cylindrical projectile. fabrics are impregnated with shear thickening fluid (stf). the effects of the (stf) have been considered as frictional effect. the stf has been made (nano silica and polyethylene glycol (peg)) and then diluted by ethanol proportion of 3:1. yarn pulling out test from in...

introduction one of the critical issues associated with sustainability in the twenty-first century is how cities are growing and developing in the space. rapid urban growth and physical development of cities cause disintegration of the spatial organization of cities and consequently spatial inequality between urban spaces. this phenomenon can be considered as spatial segregation or fragmentatio...

This study examines the impact of globalization on historic urban fabric Mutrah, with a specific focus coastal neighbourhood Sur al Lawatiyah and development souq Mutrah in Muscat, Oman. The city's design reflects its challenging fractured history, marked by fortified walls, towering forts, dense, clustered fabric, particularly during after Portuguese occupation. Additionally, explains how soci...

Technological upgrading in recent decades has allowed, at the urban level, definition of new tools to address issues related climate change. The research focuses on methodologies and technologies that are useful for morphometric classifications (RLCZ, Rome Local Climate Zone) consequent construction specific parametric models fabric historic city, starting from case study city Rome. This is sup...

Historic city centers have undergone urban development during times, which been accompanied by processes of change, so The problem was the historical fabric Najaf and lack knowledge its suitability for elderly pedestrians, especially as it is a center religious tourism. To achieve goal knowing most possible way to walk use in sports well. structure represented introduction review several concep...

Conservation of heritage areas is one the popular topics in many contemporary studies. Historic Cairo teeming with historical monuments and landmarks that bear witness to an abundance wealth evolved, not only as historic capital Islamic world but exquisite, stunning amalgamation ancient human ingenuity, regardless Cairo's international regional importance. It subjected extreme deterioration due...

We have examined the fabric-to-metal surface and fabric-to-fabric frictional characteristics (in both warp and weft directions) of a series of fabrics containing 100% polyester, 100% viscose, and P/C & P/V blends with different blend proportions. It has been observed that the normal load and the frictional force follow a logarithmic relationship for all the fabrics. The nature of fabric frictio...
