car body lightening and crashworthiness are two important objectives of car design. due to their excellent performance, composite materials are extensively used in the car industries. in addition, reducing the weight of vehicle is effective in decreasing the fuel consumption. hat shape energy absorber is used in car’s doors for side impact protection. the aim of these numerical models and exper...

The energy absorption of concrete filled, hollow-steel bracing was analyzed respect to geometric and mechanical parameters including the width-to-thickness section ratio, slenderness level, and strength of the steel and concrete. Local buckling and ductility were also investigated with respect to variation in the cross-section. The infill increased the compression resistance, even after multipl...

bhw = half width of the line broadening, Å Eabs = integrated absorption energy,W=cm Eabs;p = absorption energy per particle, W Eemis = integrated emission energy,W=cm Eemis;p = emission energy per particle, W Eray = energy of a ray, photon bundle, W Fnum = Number of particles represented by a simulated particle i = cell index in the x direction j = cell index in the r direction k = line index k...

Significant production of breath hydrogen has been shown in premature infants, suggesting limited intestinal capacity for digestion of carbohydrate. To evaluate net absorption of carbohydrate 24 three day balance studies were carried out in seven preterm infants fed pasteurised banked human milk and in 17 preterm infants fed a formula containing 75% lactose and 25% glucose polymers. Because car...
