Near Earth''s surface, where ozone comes into direct contact with life forms, it primarily displays a destructive side. Because it reacts strongly with other molecules, large concentrations of ozone near the ground prove toxic to living things. At higher altitudes, where 90 percent of our planet''s ozone resides, it does a remarkable job of absorbing ultraviolet radiation. In the absence of this ...
It is mobile application which helps the user to detect monuments and provide information about that particular monument it can run on both android as well as ios devices. It will be very helpful for foreign tourist that visits India and people fool them by providing false information about the monument so we came up with the idea of building an application whose name is TourBuddy.

Ozone detection In the chemiluminescent detection of nitrogen oxides, a constant source of ozone reacts with a metered air sample containing nitric et al. suggested that this method could also be used for ozone detection by using a constant nitric oxide source for reaction with ozone in the air sample. The ozonenitric oxide reaction is carried out at reduced pressure, to avoid ...
When the antarctic ozone hole does breakup, the ozonedepleted air drifts out into nearby areas. Decreases in the ozone level of up to 10% have been reported in New Zealand in the month following the breakup of the antarctic ozone hole [WMO 1991] [Atkinson et ] [Roy et al. 1990]
A vessel ( 102 ) containing a detector solution ( 101 ) is prepared. The detector solution ( 101 ) is an aqueous solution prepared by dissolving a detector component containing a dye which changes its color when reacting with ozone gas, a humectant, and an ultraviolet absorber having a hydrophilic group. A prepared sheetlike carrier ( 103 ) is dipped in the detector solution ( 101 ) for, ...
