A short series of experiments was conducted with the aim of assessing the possible effect of tunnel blockage on spanwise correlation lengths measured in the near-wake of a circular cylinder. The results indicate that increasing blockage acts to increase spanwise correlation. This finding has important implications for the conduct and reporting of both physical and numerical experiments on bluff...

We describe a novel infection-responsive coating for urinary catheters that provides a clear visual early warning of Proteus mirabilis infection and subsequent blockage. The crystalline biofilms of P. mirabilis can cause serious complications for patients undergoing long-term bladder catheterisation. Healthy urine is around pH 6, bacterial urease increases urine pH leading to the precipitation ...

The involvement of p53 and p21 signal pathway in the G2/M cell cycle progression of zinc-supplemented normal human bronchial epithelial (NHBE) cells was examined using the small interferring RNA (siRNA) approach. Cells were cultured for one passage in a different concentration of zinc: <0.4 microM (ZD) as zinc deficient; 4 microM as normal zinc level (ZN) in culture medium; 16 microM (ZA) as no...

In this paper, the blockage problem of optical link between AGV (autonomous ground vehicles) and AP (access point) in logistics–warehousing VLC (visible light communication) network is analyzed. First, based on random geometric model, a link-blockage model proposed. Given position AGV, obstacle, state can be obtained through model. Then, an AP-placement scheme Under placement, AGVs any have rel...
