environmental noise pollution is among the most urban problems which can be caused due to real sources like traffic, train and virtual sources provided by rigid surfaces. one of the urban structures in which can perform as a virtual noise source are the installed gutters alongside highways. these structures are mostly used to pass the wastewater or the rainfall. in this research, the acoustical...

A ConservativeMethod to Gutter Splint Ingrown Toenails Ingrown toenails can be due to trauma, improper nail cutting, and/or anatomic abnormalities of the nail apparatus. In the setting of normal anatomy, they are usually treated conservatively, but the presence of a sharp edge of the nail in the ulcer may prevent wound healing. Isolation of the nail plate from the ulcer bed using a gutter-shape...

Industrial membranes comprised of a thin selective layer (<100 nm) requires a gutter layer (<100 nm) between the selective layer and the porous support to achieve high permeance for gas separation. The gutter layer materials must be carefully chosen to enhance overall membrane performance, i.e., high permeance and high selectivity. However, the experimental determination of the optimum gutter l...

This study compared quantitatively and qualitatively the DNA extracted from buccal cells collected from the upper or lower gutter areas. Buccal cells were collected from the upper (n=15) and lower gutter (n=15) region from 15 volunteers using a special cytobrush (Gentra), totaling 2 collections from each individual. DNA was extracted from the samples according to the manufacturer's instructions...

Who are the vagrants that we try our best to avoid in the city streets? How have they reached such a state of hopelessness and destitution? Do we care anyway?
