The use of composite materials has grown exponentially in transport structures due to their weight reduction advantages, added capability adapt the material properties and internal micro-structure requirements application. This flexibility allows design highly efficient that can reduce environmental impact transport, especially if used composites are bio-based. In order structures, numerical mo...

In this paper, for the first time, we report manufacturing and characterization of large UHTCMCs discs, made a ZrB2/SiC matrix reinforced with PyC-coated PAN-based carbon fibres. This work was result long term collaboration between different institutions shows how it is possible to scale-up production process fabrication components. 150 mm discs were produced by filament winding consolidated sp...

The paper presents a dynamic data-driven mixed reality environment to complement a full-scale bio-terror preparedness exercise. The environment consists of a simulation of the virtual geographic locations involved in the exercise scenario, along with an artificially intelligent agent-based population. The crisis scenario, like the epidemiology of a disease or the plume of a chemical spill or ra...

background : nurses play a crucial role in patient-care. therefore, assessing nurses’ clinical competence is essential to achieve qualified and safe care. the aim of this study was to determine and compare the competence assessments made by head nurses and practicing nurses in a university hospital in iran in 2009. methods : a cross-sectional survey was conducted to make comparisons of both sel...
