Silica aerogel possesses an ultra-low thermal conductivity by virtue of its nano-structure. Owing to the fragility monolithic aerogel, development and production aerogel-based insulation materials involve incorporation granular with other form composite materials. In present study, application silica-aerogel-incorporated cement paste as render on roof-top surface is coupled installation a novel...

The goal of the present study was to determine whether Coptotermes formosanus Shiraki workers exposed to boron-treated wood were capable of transferring quantifiable amounts of boron to non-exposed nestmates. This effect is called horizontal transfer. Borates are not repellent to termites, nor do they cause rapid mortality, making them excellent candidates for the study of horizontal transfer. ...

According to agency theory, board of directors plays an important monitoring role in reducing information asymmetry and increasing the transparency of financial statements and social responsibility. This research is concerned with examining board diversity and social responsibility of the firms listed on the Tehran Stock Exchange during the years 2011-2015. To do so, a sample of 98 firms was se...

A flexible printed circuit board (FPCB) is flexible, thin and lightweight; however, FPCBs experience more deflection and stress in the flow environment because of fluid–structure interaction (FSI), which affects their performance. Therefore, the present study focuses to optimize a typical FPCB electronic in order to minimize the deflection and stress induced in the system. In this study, numeri...

Currently, biofibers are used as a reinforcement in polymer composites for structural elements and construction materials instead of the synthetic fibers which cause environmental problems expensive. One chemicals with pH close to neutral that can be potentially modified fiber material is sodium chloride (NaCl). Therefore, this study aims investigate characteristics composite board made from Na...
