The effects of various growing substrates, combinations of soil, silt, sand, press mud (PM) and rice hulls (RH) on plant growth, yield and quality of rose (Rosa hybrida L.) cvs. Kardinal, Anjlique and Gold Medal, were studied to standardize substrates for cut rose production and develop better management and quality production protocol. Plant height, number of leaves branch, leaf area, number o...

Heat flow controls the design and operation of a wide range engineered geosystems. This study uses transient thermal probe measurements to determine evolution conductivity air-dry water-saturated sand–silt mixtures as function effective stress. Results confirm that soils varies with state stress, dry mass density, mineralogy, pore fluid properties highlight effect contact resistance on granular...

The geological effects of rock blasting in silt-rock strata are complex, and the vibrations caused by threaten safety inhabitable areas. Based on measured data for at site dynamic finite element simulations, propagation characteristics were studied. surface, vertical vibration velocities from surface to tunnel, attenuation along tunnel’s axis analyzed. results this study as followings: directio...

Real-time quantitative PCR assays, targeting part of the ammonia-monooxygenase (amoA), nitrous oxide reductase (nosZ), and 16S rRNA genes were coupled with (15)N pool dilution techniques to investigate the effects of long-term agricultural management practices on potential gross N mineralization and nitrification rates, as well as ammonia-oxidizing bacteria (AOB), denitrifier, and total bacteri...
