But if he had spelled out his new ideas in early 2006, says Mr Chew, "there would have been a lot of scepticism" .

Arun Sarin, Vodafone's chief executive, last month said he was interested in "selective acquisitions" .

It seems fitting that it was the acquisition of an Indian firm that sealed the turnaround in Mr Sarin's fortunes.

It was partly down to luck, but Mr Sarin's survival ultimately proved to be in shareholders' long-term interests.

Nerve agents such as Sarin, Tabun and Soman are parts of organic phosphorus esters to which organophosphorus pesticide belong.

As an inhibitor of the nervous system enzyme acetylcholinesterase, sarin can cause convulsions, stoppage of breathing and death.

Many investors were livid: Vodafone's acquisition spree was supposed to be over, and Mr Sarin was accused of paying far too much for Telsim.

There was infighting on the board worthy of a medieval court, and it ended only when Mr Sarin purged his predecessor's lieutenants.

It was the world's first major chemical attack using sarin, a nerve agent which attacks the respiratory system.

Shareholders, though they staged a revolt against his leadership in 2006, ended up benefiting from Mr. Sarin's time at the helm as well.

The nerve gas sarin is a potent inhibitor of an enzyme important for synaptic transmission in nerve tissue.

Meanwhile, Mr. Sarin didn't go far enough integrating the company's far-flung operations.

Investors also wanted Mr Sarin to sell the company's stake in Verizon Wireless, a big American operator.

Sarin offers a very competitive package including good base salary, social benefits, 5 days working week and extended holidays.

Hundreds of thousands of people have been affected by e. g. the nerve gases Sarin and VX.

Prof. Sarin: Bleeding from gastric varices is a major cause of death in portal hypertension.

Mr Sarin's successor will be his deputy, Vittorio Colao, an Italian who runs Vodafone's European operations.

Mr Sarin's Indian roots were an asset during the fight for Hutchison Essar.

The most common approach with any organic chemical (whether it be paint fumes or a nerve toxin like Sarin) is activated charcoal.

When it was over , more than 5, 000 people had been poisoned by sarin nerve gas , 12 died .

The lethal dose for Sarin is 30 micrograms per kilogram of body weight, so three milligrams would kill most people.

He had studied viruses and genetic engineering at university and helped make the sarin gas.

"His big challenge is to figure out that bit, " says Mr Sarin.

Mr Sarin said WiMax should be harmonised with LTE, adding that Vodafone is planning to roll out 4G networks from 2010.

Prof. Sarin: Sclerotherapy can lead to worsening of portal hypertensive gastropathy because the major drainage vessel is blocked.

Sarin is to be feared because it is invisible, odourless and 500 times more deadly than cyanide.

That attack, which used a nerve-gas called sarin, killed 12 people and severely injured another 50.

The threat of sarin gas is not new.

Cardiac damage detected in sarin-exposed mice at 10 weeks, but not earlier, included.

Some 13 people were killed when the group released sarin gas in the metro.

When Arun Sarin was boss of Vodafone, he sent his top executives to India to learn about its low-cost business model.

The sarin attack on three railway lines in the Japanese capital killed 12 people and injured more than 5, 000 in March 1995.

Do you remember the Japanese sarin gas attack 13 years ago that caused disastrous damage?

This prompted Mr Sarin to take control of several operators in developing countries that still boast rapid growth.

Even some people in the industry, such as Arun Sarin[9], the chief executive of Vodafone[10], have their doubts.
