One of the main challenges of environment planning is to identify a model that connects all factors that determine the carbon cycle, that is: ocean-terrestrial ecosystem-anthropogenic emissions-atmosphere. Basic principle ...

[1] It is shown that ion-acoustic waves propagating along an external magnetic field and generated by parametric decays of circularly polarized finite amplitude waves have the properties of ion-acoustic waves observed ...

We performed comparative studies of the pathogenicity of six strains of Paracoccidioides brasiliensis (Bt-9, Bt-4, Pb-9, Pb-18, Bt-7 and B-1183) for young adult male ddY mice and growth rate of each strain under different ...
