Now a days, a critical problems are a fundamental component contributing to the overall performance of critical infrastructure in real environment. There is a problem in Harbor protection because of limited capability of sensor nodes. First, need to secure the busy harbor area and the vast near coast from intrusions of third person, particularly pirates smugglers, illegal fisherman, etc… In this paper, an innovative result for Craft Invasion Recognition. For that, evaluate the evaluate the small sensor nodes instead of doing with the large sensor. Then to deploys the three-axis accelerometer sensors to bring the effective actions and also provides privacy and security process, in that way it is used for the private communication from Received Signal Strength (RSS) in Wireless Sensor Networks. © Research India Publications.

Mitigation of xerophilic storage fungi-associated aflatoxin threat in culinary oil will be a new technology advantage to food industries. Groundnut oil isolate Aspergillus flavus MTCC 10680 susceptibility to Allium species (A. sativum L., A. cepa L., and A. cepa var. aggregatum) extracts, composition, and in silico confirmation of extract's phytoconstituent aflatoxin synthesis inhibition were determined. The behavior of seasoning carrier medium groundnut oil in the presence of Allium was also determined. All the Allium species extracts exhibited concentration dependent in vitro inhibition on mycelial biomass, radial growth, and toxin elaboration. The gas chromatography-mass spectrometry revealed the presence of 28, 16, and 9 compounds in the extracts of A. sativum, A. cepa, A. cepa var. aggregatum, respectively. The Allium phytocostituents-like hexadecanoic acid, 5-Octanoyl-2,4,6(1H,3H,5H)-pyrimidinetrione, Guanosine, and so on, showed higher binding energy with aflatoxin synthesis key enzyme ver1. Allium seasoning increased the typical nutty odor of the groundnut oil with sweet aroma note as well as intensification of pale yellow color. Allium seasoning exhibited the highest aflatoxin detoxification and aroma development without any nutritional loss. Culinary oil Allium seasoning has anti-aflatoxin and food additive potential for use in food industries. © 2014 Institute of Food Technologists®. Source

Ultrasonic relaxation studies have been carried out in aqueous solutions of biological surfactants namely bile salts (sodium cholate and sodium deoxy cholate) at 303.15 K in the concentration range 1 to 14 mM and in the frequency range 2-30 MHz. The ultrasonic velocity is determined at 2 MHz using a Digital Ultrasonic velocity meter. The ultrasonic absorption is measured in the frequency range 2-30 MHz using Fallen Instruments and Pulsed Power Oscillator systems. The variation in the ultrasonic absorption is explained on the basis of exchange of a surfactant monomer between the micelles and the surrounding bulk solution. An attempt has also been made to extend the application of Aniansson and Wall and Teubner models to explain the micellar kinetics of biological surfactants which is otherwise applied to explain the kinetics of ordinary surfactants only. Various kinetic parameters such as associative rate constant (k+1), dissociative rate constant (k-1) and the volume change (λV) for the monomer-micelle exchange are estimated and reported in this paper. © 2014 Elsevier B.V.

Apparent molar volume, ultrasonic velocity and absorption studies have been carried out in aqueous solutions of some bile salts namely sodium cholate and sodium deoxycholate containing 10% (v/v) of dioxane, dimethyl sulphoxide, dimethyl formamide, tetrahydrofuran and acetonitrile. These studies are carried out in the bile salt concentration of 1-15. mM at a fixed frequency of 2. MHz and at a fixed temperature of 303.15. K. The variation of apparent molar volume and ultrasonic velocity in aqueous solutions of bile salts containing 10% (v/v) of dioxane, dimethyl sulphoxide, dimethyl formamide, tetrahydrofuran and acetonitrile with bile salt concentration exhibiting break at critical micelle concentration (CMC). The observed absorption increases with increasing bile salt concentration and also exhibiting a break at CMC similar to velocity curve. The results are discussed in terms of formation of bile salt micelles through hydrophobic interaction and hydrogen bonding. The results obtained from apparent molar volume, ultrasonic velocity and apparent molar compressibility studies are confirmed by the equivalent conductance measurements carried out in the solutions of bile salts. © 2013 Elsevier B.V.

Antifungal and antiaflatoxigenic potential of culinary plant Murraya koenigii and its culinary oil food additive potential were reported. Aspergillus sp. obtained were evaluated for their aflatoxigenic xerophilic potential. The fungitoxicity of extracts on highly aflatoxigenic xerophilic A. flavus MTCC10680 isolate was determined using poisoned food technique. The biomass mycelial dry weight and aflatoxin B1 (AFB1) production was also measured. The oil samples were fried with M. koenigii leaves and the changes in aflatoxin reduction, endogenous fatty acid (FA) composition and other quality parameters in artificially contaminated samples were determined. Bioactive component Gas Chromatography Mass Spectroscopy (GC-MS) analyses and its in silico interaction with modeled ver1 protein were also determined. The mean values of quality parameters indicated the conformation of the samples to the prescribed standards. Frying artificially contaminated oil with M. koenigii showed reductions of 72% AFB1 and 73.58% AFB2 with no strategic FA compositional change. All the extracts showed differential phytochemical extraction, varied mycelial as well as aflatoxin inhibitory activity. The methanol extract showed 99.34% AFB1 and 99.6% AFB2 inhibition. 13 bioactive compounds were shown to interact with ver1 protein. Frying oil with M. koenigii could lead to long storage reduction in aflatoxin and frying performance increase without nutritional loss. © 2013 Elsevier Ltd. Source
