We consider classical dynamics of a one-dimensional system of N particles bouncing on an oscillating mirror in the presence of gravitational field.The particles behave like hard balls and they are resonantly driven by the mirror.We identify the manifolds FR Outerwear the particles move on and derive the effective secular Hamiltonian for resonant mo

The term stress is an important but vague Skincare and makeup set term in plant biology.We show situations in which thinking in terms of stress is profitably replaced by quantifying distance from functionally optimal scaling relationships between plant parts.These relationships include, for example, the often-cited one between leaf area and sapwood
