Integral equations have been widely used to solve EM scattering problems, including those arising in geophysical prospecting and antenna applications. Hohmann (1971) first discussed the application of integral equations to the simulation of two-dimensional (2D) subsurface geophysical problems. Since then, a number of applications and developments have been reported that include 3D EM scattering...

Riverstrahler is a process-based model of nutrient transfer and biogeochemical functioning of large river systems (Billen et al., 1994; Garnier et al, 1995; Billen & Garnier, 2000) at the seasonal scale. Its essence lies in the coupling of an original representation of the drainage network, partly based on the streamorder classification of Strahler (1957), with a detailed model of biogeochemica...

The expression of genes of biogeochemical interest in calcifying and noncalcifying life stages of the coccolithophore Emiliania huxleyi was investigated. Transcripts potentially involved in calcification were tested through a light-dark cycle. These transcripts were more abundant in calcifying cells and were upregulated in the light. Their application as potential candidates for in situ biogeoc...

Actinobacteria are known to produce various secondary metabolites having antibiotic effects. This study assessed the antimicrobial potential of actinobacteria isolated from the rhizosphere of Caesalpinia pyramidalis Tul. from the Caatinga biome. Sixty-eight actinobacteria isolates were evaluated for antimicrobial activity against different microorganisms by disk diffusion and submerged fermenta...
