Landau Levels and Quantum Group [PDF]
, 1993 We find a quantum group structure in two-dimensional motions of a nonrelativistic electron in a uniform magnetic field and in a periodic potential. The representation basis of the quantum algebra is composed of wavefunctions of the system.

Methodology adjustments for organic acid tolerance studies in oat under hydroponic systems
Brazilian Archives of Biology and Technology, 2009 The occurrence of anaerobic conditions in hydromorphic soils favors the development of anaerobic microorganisms that produce phytotoxic substances representing primarily by organic acids. The selection of promising oat (Avena sativa L.) genotypes for use
