TIME DEPENDENT DEFORMATIONS OF A COUPLED BRIDGE: A CASE STUDY
The bridge's span structure comprises a connected beam designed to support a concrete slab poured over parallel steel supports. Simultaneously, segmental construction, shrinkage, and the flow of concrete play a significant role in stress redistribution over time. The span construction is statically indeterminate due to its connections with the abut...

SIGNIFICANCE OF HARVEST RESIDUES IN SUSTAINABLE MANAGEMENT OF ARABLE LAND I. DECOMPOSITION OF HARVEST RESIDUES
Harvest residues are parts of cultivated plants that remain on the plot after harvest or grazing. Decomposition of plant residues by microorganisms involves two simultaneous processes: mineralization and humification of carbon compounds. Decomposition processes depend on the type of plant residues, edaphic factors and residue management factors. Ed...
