Purpose The current study was aimed to evaluate the bioaccumulation of elements(As,Cd,Cu,Fe,Mn,Se and Zn)in the gills,liver and muscle of three distinct marine fish species,namely Nemipterus japonicas,Upeneus vittatus and Pampus argenteus species were collected from Visakhapatnam to Kakinada coastal *** The fish tissues were analyzed for trace metals using energy-dispersive X-ray fluorescence(EDXRF).To ensure the quality control,reliability of the experimental validation,two certified reference materials(CRMs)procured from National Institute of Standards and Testing(NIST SRM 1577c-Bovine Liver)and European Commission-Joint Research Centre,Institute for Reference Materials and Measurements(ERMBB422-Fish muscle)were analyzed using *** The evaluated estimated daily intake(EDI)values for each metal are below the reference dose levels established by World Health Organisation(WHO).The target hazard quotient(THQ)values of both the locations of the present study are lower than one(1)showing the presence of health *** cancer risk(CR)factor value for arsenic was below the acceptable lifetime carcinogenic risk(10^(–5)).The levels of heavy metals varied significantly among three fish species and *** mean concentrations of As,Cd,Cu,Fe,Mn,Se and Zn were slightly higher than the Ministry of Agriculture,Fisheries and Food(MAFF),Food and Agriculture Organization(FAO),Turkish food codex and Brazilian Legislation standard *** findings of this study revealed that muscles possessed the lowest concentrations mostly of all the metals when compared with liver and *** The study concluded that consumption of the muscle tissue may not pose severe health risk to human health but should be consumed moderately to prevent bioaccumulation of the metals especially As.

Cryptographic Lightweight Encryption Algorithm with Dimensionality Reduction in Edge Computing

Computer Systems Science & Engineering 2022年第9期42卷 1121-1132页

作者： D.Jerusha T.jaya CSI Institute of Technology NagercoilIndia

Edge Computing is one of the radically evolving systems through generations as it is able to effectively meet the data saving standards of consumers,providers and the workers. Requisition for Edge Computing based items havebeen increasing tremendously. Apart from the advantages it holds, there remainlots of objections and restrictions, which hinders it from accomplishing the needof consumers all around the world. Some of the limitations are constraints oncomputing and hardware, functions and accessibility, remote administration andconnectivity. There is also a backlog in security due to its inability to create a trustbetween devices involved in encryption and decryption. This is because securityof data greatly depends upon faster encryption and decryption in order to transferit. In addition, its devices are considerably exposed to side channel attacks,including Power Analysis attacks that are capable of overturning the *** space and the ability of it is one of the most challenging tasks. Toprevail over from this issue we are proposing a Cryptographic LightweightEncryption Algorithm with Dimensionality Reduction in Edge Computing. Thet-Distributed Stochastic Neighbor Embedding is one of the efficient dimensionality reduction technique that greatly decreases the size of the non-linear data. Thethree dimensional image data obtained from the system, which are connected withit, are dimensionally reduced, and then lightweight encryption algorithm isemployed. Hence, the security backlog can be solved effectively using thismethod.
