The antimicrobial and antioxidant effects of different spice extracts in raw chicken meat during storage for 15 days at 4 °C were studied. Raw chicken meat was treated with BHT (positive control), Syzygium aromaticum (SA), Cinnmomum cassia (CC), Origanum vulgare (OV), and Brassica nigra (BN) extracts and the different combinations as well as the results were compared to raw chicken meat without any additive (negative control). The antioxidant and antimicrobial activities of spice extracts were determined. Total phenolic contents and flavonoid contents were ranged from 14.09 ± 0.78 to 24.65 ± 0.83 mg of GAE/g and 7.07 ± 0.15 to 12.13 ± 0.24 mg of quercetin/g, respectively. The pH, instrumental color (CIE L*, a*, b*), total viable counts (TVC), Lactic Acid Bacteria (LAB) counts, Enterobacteriaceae counts, Pseudomonas spp. counts and 2-thiobarbituric acid reactive substances (TBARS) were determined at a gap of 3 days interval for a period of 15 days. The bacterial counts of T-W-SA + T-W-CC + T-W-OV samples were lower than control samples during storage. T-W-SA + T-W-CC + T-W-OV samples maintained significantly (P < 0.05) higher L*, a* and b* values while storing. The TBARS values of T-W-SA + T-W-CC + T-W-OV samples were lowest among the samples. These results show that spice extracts are very effective against microbial growth, lipid oxidation and has potential as a natural antioxidant in raw chicken meats.
CLUSTERING IN WIRELESS SENSOR NETWORKS: A SURVEY
(International Journal of Computer Trends and Technology (IJCTT), 2014) Nithya A; Sasikala M
Wireless Sensor network (WSN) has emerged as a useful supplement to the modern wireless communication networks. Most suitable option of ways for information transfer finally ends up in saving of energy consumption resulting in increase of network lifetime of Wireless device Networks. Many routing, authority board, and information dissemination protocols area unit specifically titled for WSNs where energy awareness is a vital style issue. Routing protocols in WSNs may dissent reckoning on the appliance and specification as there is still no agreement on a tough and quick communication stack for WSN. Newer Routing protocols area unit required to cater to the requirement of present and pervasive computing. In this paper, WSN Routing Protocols has been classified in four ways in which i.e., routing ways establishment, network structure, protocol operation and leader of communications. Further, routing protocols area unit classified on the thought of their homogeneity and non uniformity of device nodes followed by the factors of clustered and non -clustered among every. Information aggregation, support for question and quality of the network of these routing protocols have what is more been.
RECEIVED SIGNAL STRENGTH BASED INDOOR POSITIONING WITH RFID
(IEEE, 2021-10-06) Sasikala M; Athena J; Sheela Rini A
Contextual information of mobile devices is necessary in location based services. This location information is used in extending tracking objects or navigation services from outdoor to indoor. High quality services are provided by GPS in outdoor applications. Since GPS is not providing accurate positioning in indoor many researchers move on to indoor positioning with different technologies like Blue Tooth, UWB, WiFi and RFID. RFID based positioning is preferred due to low cost devices and improved accuracy. This proposed system is focused on Received Signal Strength measured from RFID tags. An experimental result shows better improvement when compared with regression and Gaussian algorithms. It can be used in real time applications for Location identification.
