The mechanical properties of viscoelastic (VE) dampers directly affect the aseismic performance viscoelastically damped structures; therefore, it is great significance to accurately describe nonlinear characteristics VE in design and analysis structures. However, most existing mathematical models for have been established from a macroscopic perspective, there general lack comprehensive connecti...

pearl millet has tolerance to harsh growing conditions such as drought. it is at least equivalent to maize and generally superior to sorghum in protein content and metabolizable energy levels. thus it is of importance for poultry feeding. amino acid (aa) determination is expensive and time consuming. therefore nutritionists have prompted a search for alternatives to estimate aa levels. traditio...
