Combined sewer sediment properties were studied in small-scale laboratory ̄umes. Physical and biological characteristics of freshly remoulded sediment beds and beds undisturbed for 1±4 days were examined. When sediment beds were incubated for 1±2 days, the beds became covered with bio®lm and the bed volumes increased by 20±40% due to the formation of methane-®lled cavities. The bed strength dec...
[1] This study achieves the first high‐spatial‐resolution, layer‐scale, measured stratigraphic column of the Martian north polar layered deposits using a 1m‐posting DEM. The marker beds found throughout the upper North Polar Layered Deposits range in thickness from 1.6 m–16.0 m +/− 1.4 m, and 6 of 13 marker beds are separated by ∼25–35 m. Thin‐layer sets have average layer separations of 1.6 m....
background: one of the important aspects of equity in health is equality in the distribution of resources in this sector. the present study aimed to assess the distribution of hospital beds in shiraz in 2014. methods: in this retrospective cross-sectional study, the population density index and fair distribution of beds were analyzed by lorenz curve and gini coefficient, respectively. descrip...
