This paper proposes a formulation of dynamic contact problems which enables exact algorithmic conservation of linear momentum, angular momentum, and energy in ΓΏnite element simulations. It is seen that a Lagrange multiplier enforcement of an appropriate contact rate constraint produces these conserv
The possibility of protecting an orchard against cold by enclosing it under a screen cover was studied in a preliminary field test. At the onset of freezing temperatures, water was sprinkled on the screen, forming a continuous sheet of thin ice. The screen and ice cover effectively reduced heat loss
The distinctive relationships between landscape change, habitat fragmentation, and biodiversity conservation are highlighted in this original and useful guide to the theory and practice of ecological landscape design. Using original, ecologically based landscape design principles, the text underscor
