was a gas leak incident in India‚ considered one of the world’s worst industrial catastrophes.[1] It occurred on the night of December 2–3‚ 1984 at the Union Carbide India Limited (UCIL) pesticide plant in Bhopal‚ Madhya Pradesh‚ India. A leak of methyl isocyanate gas and other chemicals from the plant resulted in the exposure of hundreds of thousands of people. Estimates vary on the death toll. The official immediate death toll was 2‚259 and the government of Madhya Pradesh has confirmed a total

The modern environmental justice movement began in the mid- 20th century‚ when the country realized that the environment needed help. This movement throughout the last several decades has evolved from protecting woodland areas from deforestation to protection against the gas industry. Hydraulic fracturing is the process by which natural gas is extracted from the earth’s shales. The process begins with drilling through several layers of the earth‚ like the freshwater aquifer. Next‚ water with

In the practical sessions template DNA that had the EZH2 (Enhancer of zeste homolog 2) gene already cloned onto it was firstly amplified by PCR‚ then cloned in the pBluescript plasmid vector. EZH2 is an enzyme which adds methyl groups to the twenty seventh amino acid (Lysine) and is encoded by EZH2‚ the EZH2 gene encodes part of the Polycomb group which make protein complexes that help to maintain genes transcriptional repressive state over successive cell generations. http://www.ncbi.nlm.nih.gov/gene/2146

INTRODUCTION: The word ‘disaster’ is synonymous with ‘emergency’. A disaster is a natural or man-made (or technological) hazard resulting in an event of substantial extent causing significant physical damage or destruction‚ loss of life‚ or drastic change to the environment. A disaster can be defined as any tragic event stemming from events such as earthquakes‚ floods‚ catastrophic accidents‚ fires‚ or explosions. It is a phenomenon that can cause damage to life and property and destroy the economic

Experiment No. ___________________ Date ___________________ NEUTRALIZATION TITRATIONS INTRODUCTION The neutralization of hydronium or hydroxide ion to form water is widely used as the basis for volumetric determinations of acids‚ bases and salts of weak acids. The reaction is characterized by a rapid change in pH near the equivalence point‚ a change that is readily detected by an acid-base indicator or that can be followed electrically by use of a pH meter.

ASSIGNMENT 1 TITLE:BHOPAL DISASTER DATE: 30 NOVEMBER 2009 1. Abstract The night of 3rd December marked an industrial disaster when more than 40 tons of methyl isocyanate gas leaked from a pesticide plant in Bhopal‚ India that instantly led to the death of approximately 3‚800 people and causing permanent injuries for thousands more. The company involved shamelessly tried to avoid its legal responsibility. Nonetheless‚ a sum of $470 million was paid as compensation‚ a considerably small amount in
