Emerging Trend in Mobile Technology for Aged People Monitoring and Parameter Reception Using GSM Technologies

ABSTRACT In recent past, the criminals frequently target mentally and physically challenged people and aged people who live alone. Hence their safety is a matter of serious concern to their relatives. Moreover their health conditions are also of important concern to their relatives who are physically far away from them. Hence it becomes necessary to develop a monitoring system that will indicate the conditions of these aged people to their relatives. Such a monitoring system involves sensors, micro controller and web based Global Systems for Mobile Communication (GSM) services for mobile communication. The project aims at developing such a monitoring system that is to be placed at the aged people premises. The sensors continuously grab the temperature conditions and indicate it to the micro controller. Micro controller activates the corresponding services to the relative's mobile under abnormal conditions. The Ethernet system then communicates to the relative's mobile through serial communication port. The embedded GSM based monitoring system serves as a reliable watchdog for the aged people living alone. In case of any critical situation, the proposed monitoring system provides the information to the relatives through GSM modem. It also helps the relatives to know about the current location of the aged people

SUPPLEMENTATION OF SUGARY PRODUCTS TO THE MULBERRY SILK WORM, BOMBYX MORI TO ENHANCE ECONOMIC CHARACTERISTICS.

The feeding efficiency of mulberry silkworm Bombyx mon was tested by supplementing mulberry leaves coated with three types of sweety products, Palmyrajaggary, Protinex - jaggary and honey - jaggary. The silkworms fed with mulberry leaves that were coated with jaggery and Protinex - jaggary showed a higher feed consumption rate and conversion efficiencies when compared with control. Also the high consumption of mulberry leaves supplemented and that were coated with sugary products increasd the economic parameters of the silkworm. Jaggery and Protinex - jaggary provided worms showed an increase in cocoon weight (18.43%, 16.01%), shell ratio (34.0%, 26.6%) and filament length (15.9%, 40.3%). Also the incidence of.bacterial infection was less in jaggary - Prôtinex trated worms. This observation adds an interesting note that the silkworm B. mon too prefers sugary products like other insects

GREEN SYNTHESIS AND EVALUATION OF BIOLOGICAL IMPACT OF Zn(II), Cd(II) AND Hg(II) COMPLEXES WITH PHENYLACETYLUREA AND BUTANOATE ION LIGANDS

Objective: To prepare Zn(II), Cd(II) and Hg(II) complexes containing Phenylacetyl urea (PAU), and butanoate (but) ligands and to characterize physic-chemical, spectral and biological properties. Methods: All the three metal complexes were prepared by the addition of required mole ratios of phenylacetylurea in methanol and sodium butanoate in ethanol to the methanolic metal nitrate solutions followed by microwave irradiation for ~10 seconds after each addition of ligands. The precipitated complexes were filtered, washed with ethanol and dried. The molecular formulae and probable geometry of the complexes were arrived at from the estimation of metals, electrical conductivities and electronic spectral data. The antimicrobial and anti fungal screening of the complexes against the bacteria, viz., Staphylococcus sp, Escherichia coli, Shigella flexneri, Raoultella planticola, Pseudomonas aeruginosa and fungi, viz., Candida albicans, Aspergillus oryzae, Aspergillus niger, Aspergillus flavus and Aspergillus sojae were carried out by well diffusion method. Antioxidantal activities were carried out by diphenylpicrylhydrazyl (DPPH) free radical scavenging method. Results: The molecular formulae of the three complexes were arrived as [Zn(PAU)(but)2], [Cd(PAU)(but)2] and [Hg(PAU)(but)2]. The antibacterial and anti fungal activities (diameter inhibition) of the complexes were in the range of 25-36 mm at 100 µg/ml concentration and 11-30 mm at 400 µg/ml concentration respectively. The percentage inhibition of DPPH free radical scavenging of Zn(II), Cd(II) and Hg(II) complexes were 44.13, 36.25 and 24.68 respectively. Conclusion: The results indicate that all the three complexes are biologically active and the biological activities are higher than pure PAU and but ligands
