Sprayable biopolymer membranes (SBM) is an emerging mulching alternative to increase horticultural and agricultural productivity by reducing soil erosion evapo­rative losses. The SBM usually applied in liquid form directly the surface where polymer molecules a thin biodegradable film. In order test this technology, experiment was performed greenhouse conditions with goal of quantifying impact o...

The tribological properties of two smooth surfaces in the presence of a thin confined film are investigated with a generic model for the interaction between two surfaces and with computer simulations. It is shown that at large normal contact pressures, an ultra thin film automatically leads to static friction between two flat surfaces-even if the surfaces are incommensurate. Commen-surability i...

Certain commercial entities, equipment, or materials may be identified in this document in order to describe an experimental procedure or concept adequately. Such identification is not intended to imply recommendation or endorsement by the National Institute of Standards and Technology, nor is it intended to imply that the entities, materials, or equipment are necessarily the best available for...

This work presents the absorptance of high-temperature superconducting YBa Cu O 2 3 7 d I 1 ( ) YBCO films, deposited on Si substrates, in the far infrared from 15 to 95 cm ( ) ( wav elength from 667 to 105 m m at temperatures of 100, 200, and 300 K i.e., in the ) normal state . Our experiments show a significant difference in the absorptance for radiation incident on the film side as compared ...

This paper studies the structural robustness of evolutionary models of cooperation, i.e. their sensitivity to small structural changes. To do this, we focus on the Prisoner’s Dilemma game and on the set of stochastic strategies that are conditioned on the last action of the player’s opponent. Strategies such as Tit-For-Tat (TFT) and Always-Defect (ALLD) are particular and classical cases within...

Solutions to the twisted Yang-Baxter equation arising from intertwin-ers for cyclic representations of U q (sl n) are described via two coupled the lattice current algebras.
