Anaerobic digestion is a naturally occurring biological process in which large numbers of anaerobic bacteria convert organic matter into methane and carbon dioxide (a mixture called biogas) in the absence of air. It is a widely used biological process for treating wastewater solids. This process stabilizes the organic matter in wastewater solids, reduces pathogens and odors, and reduces the tot...

Rocks and trees are often central to the lives of human communities: their role is far more complex meaningful than supplying resources, status, or symbolism. In a convivial landscape, rocks, trees, people deeply connected, showing elaborate powerful interdependencies. this article I explore idea conviviality through series examples from Archaic early twentieth-century Cyprus. The Acropolis cli...

In this study, the effect of small-scale of both nanostructure and nano-fluid flowing through it on the natural frequency and longitudinal wave propagation are investigated. Here, the stationary and axially moving single-walled carbon nanotube conveying fluid are studied. The boundary conditions for the stationary nanotube is considering clamped-clamped and pined-pined and for the axially movin...
