The light trap firstly traps, kills and disperses insects, then collects images of trapped insects and sends each image to the cloud server. Although Albert Einstein predicted BEC for massive particles in 1924, for a long time scientists considered it impossible to create a BEC made of light, because photons have no mass, which is a key requirement for a Bose-Einstein condensate. Another method is to use a plastic bottle with a piece of tape over . Sound, temperature measurements and visual inspection have proven useful to maintenance personnel in checking for malfunctioning steam traps. These findings permitted positive definition for the epidemic vectors of VE in the U.S. Test method A specifies a 30 angle for specular gloss measurement, 28 or 32 for narrow-angle reflection haze measurement and 25 or 35 for wide-angle reflection haze measurement. BOGURA: Farmers in the district are inclined towards using a light trap method to kill harmful pests in their fields to increase crop production.
