this study investigates the strategies native english and persian speakers employ for expressing gratitude in different situations. the strategies of persian efl learners are also compared with english strategies in order to find the differences that may exist between these two languages. social status and size of imposition of the favor are social variables which are investigated in detail for...
the growing interest in using natural fibers as reinforcing agents of polymer-based composites is mainly due to their advantages such as lower cost, lower density, ease of preparation, lower energy requirements for processing, biodegradability, wide availability and relative non-abrasiveness over traditional reinforcing fibers such as glass and carbon. in this study, wood-plastic composite (wpc...
Submitted for the MAR14 Meeting of The American Physical Society A scattering approach for locomotion on heterogeneous granular media1 TINGNAN ZHANG, FEIFEI QIAN, ADAM KAMOR, PREDRAG CVITANOVIC, DANIEL GOLDMAN, Georgia Institute of Technology — Locomotion on homogeneous particulate media has been recently studied using biological and robotic experiment and modeled using multi-particle discrete ...
Tannin is a very versatile industrial material found in many parts of plants such as the bark of Eucalyptus camadulensis (EC). The bark of EC that normally peels off during the dry season has usually served as anxious substrate for pathogens. In the present experiment, tannin was leached from the bark of EC using water as solvent. Tannin produced varied from 5 to 12%. The yield obtained was fou...
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
In this study, the parameters affecting the synthesis of silver nanoparticles were optimized by green chemical reduction method to make a conductive pattern. The raw materials used in this study, include silver nitrate as a source of silver ions, polyvinylpyrrolidone as surface stabilizer, and glucose as the reducing agent. Effective parameters were investigated by Taguchi statistical design,...
The effect of biochar supplementation with different particle size on biogas production in two-stage anaerobic digestion white bread waste was carried out a laboratory scale using 100 mL bioreactor. variations sizes <63 µm, <125 <149 <250 and <500 µm the addition concentration 5 g/L, 15 25 g/L were investigated to obtain optimal concentrations. Mixed cultures incubated at 35 °C f...
particle size, board density and adhesive content are the most important factors, influencing on physical and mechanical properties of particleboard. in this study the effects of density, adhesive content and particle size on withdrawal strength of particleboard made from populus (populus alba) particles have been studied. three levels of density including 0.65, 0.7, and 0.75 g/cm3, three level...
We present a versatile approach to produce macroscopic, substrate-supported arrays of plasmonic nanoparticles with well-defined interparticle spacing and a continuous particle size gradient. The arrays thus present a "plasmonic library" of locally noncoupling plasmonic particles of different sizes, which can serve as a platform for future combinatorial screening of size effects. The structures ...
