Statistical analysis of phenol concentration in groundwater of Durgapur, West Bengal, has indicated groundwater pollution by industrial effluents carrying phenolic compounds. A second degree multiple regression expression (with goodness fit of 76%) clearly shows decreasing concentration of phenol away from the potential sources. A smoothing technique called kriging to fit a 3D-scatterplot of phenol concentration by latitude and longitude has been applied to study the pattern of spatial variation of phenol concentration. Contour plot based on successive vertical slices through the surface of kriging, smoother overlaid on the data coded by phenol concentration, depicts high phenol concentration well beyond the WHO (World Health Organisation) specified potable water quality.Keywords

Cutting down the global energy consumption through efficient use of energy is one of the major research challenges among scientists. Replacing the tungsten filament bulb with novel semiconductor-based light emitting diodes (LEDs) has been a major step forward towards energy-efficiency. Organic light emitting diodes (OLEDs), the third-generation lighting systems, are even better in this move. OLEDs are organic molecules or semiconducting organic polymers that can emit light when exposed to an applied electrical current. Owing to their low-cost, low operating voltage, high energy-efficiency and longer lifetime, OLEDs are expected to soon dominate the lighting world. OLEDs can transform more than 80% of the energy into light, where the long-existing tungsten bulb can produce light out of only 1 0 % of the energy and the rest 90% get drained as heat. Apart from the lighting applications, OLEDs are also proven to dominate over their predecessor liquid crystal display (LCD) in the flat panel display technology. Some of the elegant features of OLED displays include flexibility, wider viewing angle, better contrast ratio, high resolution and ultra-thin thickness. This article has been aimed to provide a concise overview of the evolution of OLED technology and their role in energy*efficiency to the modern world.

This study traces the development of watersheds in India based on the governing guidelines of the watershed programmes. We explore the changes and modifications in the watershed guidelines and categorize the developmental changes into six distinct yet interlinked phases. We observed that the watershed guidelines were fine-tuned with emerging challenges of land degradation, livelihood security, gender and social equity, climate change mitigation and adaptations. Recently, the focus of watersheds has shifted from production centric to income-centric by promoting enabling institutional settings. The experiences and learnings from India’s watershed programmes provide insights for other developing countries implementing such programmesFull Text
