background: flow cytometry is a rapid, sensitive, and reliable method for determination of bacterial viability. here we assayed the capability of flow cytometry to detect helicobacter pylori viable cells in both forms of spiral and coccoid. methods: viable bacteria stained with rhodamin 123 and fluoresced with laser beam of 488nm. the rate of rh123 absorption was determined in both forms of bac...

An efficient source of alternative energy has yet to be developed. Solar energy, the most viable and sustainable source of renewable energy, remains less effective due to limitations in absorbing materials to convert direct sunlight into useful solar cell devices. However, this flaw can be circumvented if solar panels had the capability to convert infrared radiation into useable energy. The foc...

Optical remote sensing systems operating on the principle of differential absorption have been employed since the mid-1970s for measuring airborne species. Multiwavelength sensing approaches, such as differential absorption lidar (DIAL) and differential absorption and scattering (DAS), are used for single (or a few) species detection boasting high sensitivity and long path detection capability....

automobile light weight structural composites are subjected to the various loadings in their service lives. honeycombs are increasingly used as core structures in automobile light weight structures as energy absorbers. in this paper the energy absorption of honeycomb panels under impact of cylindrical projectile is numerically and experimentally studied. the effect of the core materials and cro...
