Don’t communalise, says Army after Owaisi reveals religion of martyred soldiers

New Delhi, Fevb 10: Of the countries most at risk of importing coronavirus cases, India ranks 17th, researchers have found on the basis of a mathematical model for the expected global spread of the virus that originated in China's Wuhan area in December 2019.

So far, India has reported three coronavirus positive cases -- all from Kerala.

Among the airports in India, the Indira Gandhi International Airport in New Delhi is most at risk, followed by airports in Mumbai, Kolkata, Bengaluru, Chennai, Hyderabad and Kochi, according to the model.

The new model for predicting global novel coronavirus cases has been developed by researchers from Humboldt University and Robert Koch Institute in Germany.

"The spread of the virus on an international scale is dominated by air travel," said the study.

"Wuhan, the seventh largest city in China with 11 million residents, was the relevant major domestic air transportation hub with many connecting international flights before the city was effectively quarantined on January 23, 2020, and the Wuhan airport was closed. By then the virus had already spread to other Chinese provinces as well as other countries," it added.

The researchers said that it is possible to estimate how likely it is that the virus spreads to other areas by looking at air travel passenger numbers.

"The busier a flight route, the more probable it is that an infected passenger travels this route. Using these probabilistic concepts, we calculate the relative import risk to other airports. When calculating the import risk, we also take into account connecting flights and travel routes that involve multiple destinations," said the study.

The top 10 countries and regions at risk of importing coronavirus cases are: Thailand, Japan, South Korea, Hong Kong, Taiwan, USA, Vietnam, Malaysia, Singapore and Cambodia, according to the model.

While Thailand's national import risk is 2.1%, it is 0.2% for India, found the research.

The foundation of the model is the worldwide air transportation network (WAN) that connects approximately 4,000 airports with more than 25,000 direct connections.

The model accounts for both, the current distribution of confirmed cases in mainland China as well as airport closures that were implemented as a mitigation strategy.

This network theoretic model is based on the concept of effective distance and is an extension of a model introduced in the 2013 paper "The Hidden Geometry of Complex, Network-Driven Contagion Phenomena" published in the journal Science.

The current outbreak of the 2019-nCoV virus started in Wuhan city, Hubei province, China. While the first cases were reported as early as December 8, 2019, the outbreak gained global attention on December 31, 2019, when the World Health Organization was alerted to "several cases of pneumonia" by an unknown virus.

The new virus was soon identified as a novel coronavirus and named 2019-nCOV. It belongs to the family of viruses that include the common cold and viruses such as SARS and MERS. On January 20, 2020, it was confirmed that the coronavirus can be transmitted between humans, greatly increasing the risk of a global spread.

The death toll due to the novel coronavirus outbreak in China has increased to 811 on Sunday, surpassing that of the Severe Acute Respiratory Syndrome (SARS) epidemic in 2003.

Although about 20 countries have confirmed cases, China has accounted for about 99 per cent of those infected. The first foreign victims of the virus both died on Saturday in Wuhan.

New Delhi, Jan 4: The Supreme Court on Thursday extended till June 12 its earlier order of May 15 asking the government not to take any coercive action against companies and employers for violation of Centre's March 29 circular for payment of full wages to employees for the lockdown period.

A bench of Justices Ashok Bhushan, S K Kaul and M R Shah reserved the verdict on a batch of petitions filed by various companies challenging the circular of the Ministry of Home Affairs issued on March 29 asking the employers to pay full wages to the employees during the nationwide lockdown due to the coronavirus pandemic.

In the proceedings conducted through video conferencing, the top court said there was a concern that workmen should not be left without pay, but there may be a situation where the industry may not have money to pay and hence, the balancing has to be done.

Meanwhile, the apex court asked the parties to file their written submissions in support of their claims.

The top court on May 15 had asked the government not to take any coercive action against the companies and employers who are unable to pay full wages to their employees during the nationwide lockdown due to the coronavirus pandemic.

The Centre also filed an affidavit justifying its March 29 direction saying that the employers claiming incapacity in paying salaries must be directed to furnish their audited balance sheets and accounts in the court.

The government has said that the March 29 directive was a "temporary measure to mitigate the financial hardship" of employees and workers, specially contractual and casual, during the lockdown period and the directions have been revoked by the authority with effect from May 18.

New Delhi, Jun 23: In an unexpected development, the pump price of diesel is all set to surpass the petrol price in the capital, making it the most expensive transport fuel for the first time in a long time.

Globally, diesel is priced slightly above petrol prices due to the very nature of the product that has a higher cost of production. But in India, due to the lopsided taxation structure, diesel attracts lesser of the tax between the two auto fuels keeping its prices lower than petrol for last several years.

Diesel is currently priced at Rs 79.40 a litre in the Capital, just 36 paise short of petrol price that is being retailed at Rs 79.76 a litre. Going by the trend of price movement in the two products for the last few days where diesel prices have consistently increased by 50-60 paise per litre while the daily increase in petrol prices have fallen to just 20 paise on Tuesday, it is set to surpass petrol prices in next few days.

"Diesel price movement is sharper in international market and if oil companies follow the global price trend, diesel prices will surpass that of petrol later this week. It will be after many years that this would happen and is expected to sustain for some time unless government changes the tax structure of the petroleum products again," said an oil sector expert from one of the big four audit and advisory firms asking not to be named.

Interestingly, even in India the base price of diesel is expensive than petrol. According to the Indian Oil Corporation (IOC), while the base price of petrol in Delhi currently comes to Rs 22.11 per litre, the same for diesel is higher at Rs 22.93 per litre (effective from June 16, 2020). This has been the case for a long time, but retail price of petrol can be higher than diesel due to central and state taxes.

What has now brought diesel prices to a whisker of petrol prices in the capital is the Delhi government's decision early May to increase the Value Added Tax on diesel from 16.75 per cent to 30 per cent and on petrol from 27 per cent to 30 per cent. This increased the retail price of diesel and petrol in Delhi by Rs 7.10 and Rs 1.67 a litre respectively. With Central taxes on the two products already reaching identical levels, the Delhi governments move hastened price parity between petrol and diesel.

Currently, the Central excise on petrol is Rs 32.98 a litre while that on diesel it is Rs 31.83 a litre. The VAT on petrol in Delhi is Rs 17.71 a litre and that on diesel is Rs 17.60 a litre.

While the movement of retail pricing is being seen with a sigh of relief by vehicle owners whose cars run on petrol, those buying the relatively expensive diesel cars are now repenting on their decision. The development is also being seen with caution by automobile companies who have spent millions to ramp up their facilities for diesel run vehicles. The expectation is that demand for such cars will now fall, causing more damage to companies where sales are already impacted due to persistent economic slowdown and now the spread of COVID-19 pandemic.

"The pricing development would push automobile companies to strategies being followed by companies in the western markets where diesel run cars are not sold on fuel pricing differential, but on overall make and quality that puts them ahead of petrol run cars," the expert quoted earlier.

Yes, but for commercial vehicle sector the rising price of diesel had not been welcomed. In fact, the commercial transport sector had time an again threatened strike against the move to raise fuel prices.

With petrol and diesel retail prices closing, the case for adultering fuel has also gone down much to the relief of vehicle owners.
