Background: One of the main water contaminants are Hg, Cd, Pb and As.The chain of contamination of these metals and metalloid follows a cyclical order: Industry, atmosphere, land, water, phytoplankton, zooplankton, fish, and humans.Currently, Hg, Cd, Pb and As researches are of interest because consumption of fish with high toxic metal and metalloi
In this paper, we present a new type of symmetric encryption by converting the classical monoalphabetic affine cipher into arm tray for wheelchair a polyalphabetic cipher.The proposed encryption utilizes the properties of outer-convex dominating set in the corona of graphs to generate random keys from the shared keyword to every character of the me
Many real time problems are based on uncertainity and chaotic environment.To demonstrate this ambiguous suituation more precisely we intend to amalgamate the ideas of chaos theory and neutrosophy.Neutrosophy is a flourishing arena which conceptualizes the notions of true, falsity and indeterminacy attributes of an event.Chaos theory is another bran
There are many sample preparation australis palette methods for heavy metal detection of soil samples, but each has its advantages and disadvantages.Based on the above two pretreatment methods, the detection limit, precision, accuracy and actual soil sample measurement value of mercury detection in soil by atomic fluorescence were compared with ato
