purpose headache at altitudes has had an incidence of 25-62% through many related studies. many reasons are identified concerning headache at altitudes such as acute mountain sickness (ams), sinus headache, migraine, tension type headache, and frontal tension headache. this study tried to compare different types of headache among trekkers on mount damavand, a 5671m mountain, iran, to find their...

Composite materials are widely used because of their light weight and high strength properties. They typically made up multi-directional layers fibres, connected by a resin. The manufacturing composite parts is complex, time-consuming prone to errors. This work investigates the use robotics in field material manufacturing, which has not been well investigated date (particularly simulation). Eff...

In the domain of Automated Manufacturing Systems (AMS), Supervisory Control Theory (SCT) is a general modelbased framework, which contributes to the automated development of control systems. Although, SCT delivers important theoretical insights to deal with controllers design, its use in the industry is still weak, because of the discrepancy among its abstract controllers and their physical imp...

The escalating complexity and competitiveness in the market place require firms to constantly review and modify their strategy and the way they operate in order to survive and sustain their market positions. For manufacturing firms, adoption of more advanced manufacturing techniques is necessary for these firms to remain competitive and achieve the desired performance. In this advanced environm...

Macrophage apoptosis and the ability of phagocytes to clear these apoptotic cells are important processes in advanced atherosclerosis. Phagocytic clearance not only disposes of dead cells but usually elicits an anti-inflammatory response. To study this process in a model of advanced lesional macrophage death, macrophages rendered apoptotic by free cholesterol loading (FC-AMs) were incubated bri...
