It is shown that the standard sp(n) hybrid orbitals are orthogonal orbitals that minimize the total quadratic spread. This is done in a concise way that may improve the understanding of hybrid orbitals. The fact that ...

Symmetries are ubiquitous in a wide range of nonlinear systems. Particularly in systems whose dynamics is determined by a Lagrangian or Hamiltonian function. For hybrid systems which possess a continuous-time dynamics ...

Sweet corn (Zea mays L.) possesses wide versatility, besides adding value to the product. This corn type has been consumed ‘in natura’ in several countries, in form of cooked ears, or in frozen or canned grains. In Brazil, ...

Routine applications of DNA hybridization biosensors are often restricted by the need for regenerating the single-stranded (ss) probe for subsequent reuse. This note reports on a viable alternative to prolonged thermal or ...

O sucesso nos programas de melhoramento genético de milho depende da identificação de parentais com boa capacidade de combinação para a produção de híbridos. O objetivo deste trabalho foi identificar linhagens com boa ...

The study of adaptability and stability, as well as the predictability of genotypes regarding the study of environments is extremely important in the positioning of corn hybrids, whether they are simple or triple. The ...
