Therefore, their use cannot be stopped. These electronic gadgets emit electromagnetic radiations, which are believed to be hazardous to human health. World Health Organization/International Agency for Research on Cancer has classified radiofrequency electromagnetic fields as possibly carcinogenic to humans (Group B). The Enviro Chip developed by Synergy Environics, India, is a radiation harmonizing chip which when fixed on electronic gadgets at specific locations claims to reduce stress level by reducing the pulse rate of users which may also result in improvement of other health parameters. In this study, we have tested the ability of the Enviro Chip to reduce pulse rate of people who may have developed high pulse rate due to prolonged use of electronic gadgets. This was the double blind crossover study conducted in 205 healthy volunteers having an average pulse rate of above 82 per Minute at Max Healthcare India. The primary objective of the study was to evaluate and compare the change in pulse rate over 14 measurements with the use of both the Enviro Chip and a Dummy chip from average pulse rate at baseline without the Placebo effect. The secondary objective was to evaluate the change in pulse rate gender-wise. Data analysis was done using Wilcoxon Sign Rank test. The study demonstrated statistical significant reduction in pulse rate over 14 measurements with the use of Enviro Chip in both male and female healthy volunteers展开更多

The key to its planning is an ecological integration to make trade-off between economic wealth and environmental health, between material and spiritual civilization, between natural and human eco-cybernetics. Integration, demonstration, citizens’ participation and scientists’ and technician’s catalyzing are the key instruments for the implementation of the ecocity plan. "Clean production" and "ecological industry" are key elements in comprehensive development towards an eco-city. Beyond the technical and management questions, how to interlink production, consumption and reduction at the local and regional level, the spatial and urban dimension should be considered in order to perform an integrative urban eco-space.展开更多
