blown bitumen (110/10) was mixed with heavy vacuum slops (h.v.s), 60/70 penetration grade bitumen and recycled isotactic polypropylene (ipp) at different levels. the resulting resins were used to impregnate non-woven poly(ethylene terephthalate) fibers to form composites. the modulus and penetration grade of the resulting bituminous resins were determined. it was found that these bituminous res...
Aim of the research is to show developing legitimacy APUD-system lungs in pre and post ontogenesis. Condition neuroendocrine apparatus on rabbits was studied during fetal embryogenesis inner development after 1-180 days birth. Duration chosen according their changing afterbirth features as physiological function organism; selected periods newborn stage, enlightenment, complication locomotion, p...
A new three-dimensional unit cell model has been developed for modeling three constituent phases including inclusion, interphase and matrix. The total elastic modulus of nano-composite is evaluated. Numerical results are in good agreement with the previous proposed theoretical modeling. Higher matrix and inclusion elastic modulus both can dramatically influence the total elastic modulus.
Consider inviscid uids in a channel f 1 < y < 1g. For the Couette ow ~v0 = (y; 0), the vertical velocity of solutions to the linearized Euler equation at ~v0 decays in time. At the nonlinear level, such inviscid damping is widely open. First, we show that in any (vorticity) H s < 3 2 neighborhood of Couette ow, there exist non-parallel steady ows with arbitrary minimal horizontal period. Th...
handling of endodontic sealers is greatly dependent on their elasticity and flow ability. we compared the viscoelastic properties of three root canal sealers.ah plus (dentsply, de trey, konstanz, germany), endofill (dentsply hero, petrópolis, rio de janeiro, brazil) and ah26 (dentsply, de trey, konstanz, germany) were mixed according to the manufacturers' instructions. the resulted pastes were ...
Weak gravitational lensing has the potential to constrain cosmological parameters to high precision. However, as shown by the Shear Testing Programmes and Gravitational lensing Accuracy Testing challenges, measuring galaxy shears is a non-trivial task: various methods introduce different systematic biases which have to be accounted for. We investigate how pixel noise on the image affects the bi...
Four idealized direct numerical simulations are performed to examine the dynamics arising from the superposition of a monochromatic gravity wave (GW) and sinusoidal linear and rotary fine structure in the velocity field. These simulations are motivated by the ubiquity of such multiscale superpositions throughout the atmosphere. Three simulations explore the effects of linear fine structure alig...
Endoscopy revealed the presence of foreign bodies in the stomach, which was filled with a large volume of food (Figure 1). These foreign bodies were considered to cause intermittent gastric outlet obstruction. We tried to retrieve one of them with a polypectomy snare, but found it difficult because it had become a hard mass. Thus, we forcefully pulled it out of her mouth, causing a deep lacerat...
