This automated method, based on a modified Cantor-dust method, is applied to various artificial and natural 2D patterns.
Powder dusting method was used to visualize latent fingerprints (LFPs) by staining uncoated and coated NP on various porous and non-porous surfaces under UV light.
The most common method implied to disentangle the secrets of latent prints is "Powder Dusting Method".
Powder dusting method is used to develop latent fingerprints in this study.
In the present study, a less expensive, simple and easily accessible household materials such as cumin, Coriander powder, coriander, turmeric, black pepper, etc. have been used to disclose the mysteries of latent fingerprints on an aluminum foil by dusting method which gives good results.
Earlier, powder dusting methods including black powder (Haque et al. 1989), fluorescent powders (Kerr et al. 2013), and other synthetic food and festive colors (gulal) (Kumari et al. 2011), ninhydrin dipping (Crown 1969), iodine fuming (Jasuja et al. 2012) and silver nitrate (Dalrymple et al. 1977) were most commonly employed for the development of such prints.
Dust mask Method There are two approaches to mosaic making: direct (sticking the tile directly on to a surface) and indirect (sticking the tiles face down on paper first, then flipping on to an adhesive-coated surface).
Therefore, a new dry-type filtration dust collection method is put forward to use in the construction of large tunnels, and a dry-type filtration dust collection device is designed.
Foam is used as part of an effective dust suppression method in underground coal mines, but conventional foaming devices severely restrict its popularization and application due to the high cost of foam preparation, poor applicability and high pressure loss.
This week, Schade, 57, stood on a berm in a portion of the dry lake recently tilled to test the effectiveness of the new dust suppression method.
