Global warming and climate change: realities, uncertainties and measures
This paper is an attempt to show that global warming and climate change are real, and are greatly affecting the biosphere. Evidences suggesting that the increasing concentration of atmospheric greenhouse gases due to human activities is mainly responsible for global warming and climate change are presented. Uncertainties about the future course of global warming and climate change centred on the role of two important...

Health impact of climate change due to combustion of fossil fuel
The analysis of temperature data obtained from the National Oceanic and Atmospheric Administration (NOAA) database showed that each of the last 13 years was one of the warmest years for the last several thousand years in the temperature record. In this study, it was observed that the changes in the weather parameters such as temperature, humidity, wind etc., due to increase in greenhouse gases, adversely affect human...

Atmospheric pressure dielectric barrier discharge chemical and biological applications
Recently atmospheric pressure dielectric barrier discharge (APDBD) plays an important role in chemical, industrial and biological applications. It has been used for ozone synthesis, hydrogen production from natural gas, surface treatment including textile and polymer treatment, yeast and bacterial inactivation. The physics and mechanism of atmospheric pressure dielectric barrier discharge will be reviewed. Coaxial and...

Effective electronic waste management and recycling process involving formal and non-formal sectors
Electronics waste is becoming a crisis for the society. Huge accumulation of e-waste and their recycling through primitive means for extraction of precious metals is real concern in the developing countries as e-waste contains hazardous materials. Recycling of e-waste through proper technologies is, however, considered to be a profitable business in developed countries due to the presence of precious metals...

Synthesis and applications: Ten years of experience in monodentate, bidentate, tridentate and macrocycle pyrazole heterocyclic chemistry
Herein we report the development of efficient methods to prepare monodentate, bidentate, tridentate and macrocycle compounds based on pyrazole moieties, with the opportunity to change easily structure, substituents, cavities or all these parameters in the synthesis of huge library compounds. These methods take advantage of the vast number of commercially available starting materials containing functional and aliphatic...
