RSS firm on its vision that Bharat is 'Hindu Rashtra': Mohan Bhagwat

New Delhi, Mar 29: The total confirmed coronavirus cases in India rose to 979, including 48 foreigners, according to the Ministry of Health and Family Welfare on Sunday.
There are 867 active cases of the disease as of Sunday, out of the total confirmed cases, while 87 persons have also been cured and discharged or migrated.
The number of deaths due to the infection rose to 25.
Maharashtra and Kerala, with 186 and 182 cases, have two of the highest number of positive cases in the country, with Maharashtra also recording six deaths due to the disease.
The Central government has taken many stringent measures to prevent the further spread of the disease with a 21-day nationwide lockdown being imposed.
The disease which originated from Wuhan, China has so far close to 6 lakh reported cases from around the world with more than 25 thousand deaths being reported due to it, as per World Health Organisation on March 28. 

Washington, Apr 23: Air pollution over northern India has plummeted to a 20-year-low for this time of the year, according to satellite data published by US space agency National Aeronautics and Space Administration (NASA).
The US space agency's satellite sensors observed aerosol levels at a 20-year low post the countrywide lockdown, implemented to slow the spread of the novel coronavirus.

"We knew we would see changes in atmospheric composition in many places during the lockdown," said Pawan Gupta, a Universities Space Research Association (USRA) scientist at NASA''s Marshall Space Flight Center. "But I have never seen aerosol values so low in the Indo-Gangetic Plain at this time of year," added Mr Gupta.

Acting Assistant Secretary of State for South and Central Asia Alice G Wells tweeted, "These images from NASA were taken each spring starting in 2016 and show a 20-year low in airborne particle levels over India. When India and the world are ready to work and travel again, let's not forget that collaborative action can result in cleaner air."

The data published with maps show aerosol optical depth (AOD) in 2020 compared to the average for 2016-2019. Aerosol optical depth is a measure of how light is absorbed or reflected by airborne particles as it travels through the atmosphere.

If aerosols are concentrated near the surface, an optical depth of 1 or above indicates very hazy conditions. An optical depth, or thickness, of less than 0.1 over the entire atmospheric vertical column is considered "clean." The data were retrieved by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite.

In the first few days of the lockdown, it was difficult to observe a change in the pollution signature. "We saw an aerosol decrease in the first week of the shutdown, but that was due to a combination of rain and the lockdown," said Mr Gupta.

Around March 27, heavy rain poured over vast areas of northern India and helped clear the air of aerosols. Aerosol concentrations usually increase again after such heavy precipitation.

"After the rainfall, I was really impressed that aerosol levels did not go up and return to normal. We saw a gradual decrease and things have been staying at the level we might expect without anthropogenic emissions," Mr Gupta said.

On March 25, the Indian government placed its 1.3 billion citizens under a strict lockdown to reduce the spread of COVID-19. The countrywide mandate decreased activity at factories and severely reduced car, bus, truck and airplane traffic. Every year, aerosols from anthropogenic (human-made) sources contribute to unhealthy levels of air pollution in many Indian cities.

Aerosols are tiny solid and liquid particles suspended in the air that reduce visibility and can damage the human lungs and heart.

In southern India though, the story is a little hazier. Satellite data show aerosol levels have not yet decreased to the same extent. In fact, levels seem to be slightly higher than in the past four years. The reasons are unclear but could be related to recent weather patterns, agricultural fires, winds or other factors.

"This a model scientific experiment," Robert Levy, program leader for NASA's MODIS aerosol products, said about the lockdown and its effects on pollution.

"We have a unique opportunity to learn how the atmosphere reacts to sharp and sudden reductions in emissions from certain sectors. This can help us separate how natural and human sources of aerosols affect the atmosphere," Mr Levy added.

New Delhi, Jun 24: A litre of diesel on Wednesday was more expensive than a litre of petrol after the price of the former was hiked by 48 paise on the 18th successive day of fuel price revisions. While petrol price remained unchanged for the first time since June 7, diesel prices maintained upward trajectory to touch new highs.

It is for the first time in Delhi that diesel has become more expensive than petrol. A litre of the fuel now costs ₹79.88 as against ₹79.76 for a litre of petrol, as per a report in news agency ANI.

While surging fuel prices may generate much-needed revenue for governments, it would also have a detrimental impact on household budgets. The spike in diesel prices also has a wider impact on the transport and agricultural sectors which are largely dependent on the fuel.

The widest gap between the prices of the two fuels was on June 18 of 2012 when a litre of petrol was at ₹71.16 in Delhi while diesel was at ₹40.91. On June 28, the gap between the two fuels was 31.17 per litre in Mumbai. Around that time, there was a spurt in sales of diesel passenger vehicles while demand for such vehicles has come down significantly in current times. This has also led many manufacturers to ditch diesel engines completely.

The current trend of fuel price hikes are unlikely to do demand for petrol vehicles much good either.

Daily price revisions of the two fuel had been temporarily halted for 83 days till it was resumed on June 7.

India's demand for fuel doubled in May and has been steadily rising in June with the easing of restrictions. Indian refineries have already scaled up crude processing with Indian Oil Corp, the country's top refiner, looking to operate its plants at about 90% capacity in June.

The rising fuel prices, however, have resulted in political uproar with Congress leading the charge against the central government and accusing it of penalising consumers by imposing high taxes. A demand for including fuel prices under Goods and Services Tax (GST) has also been renewed by many but it is highly unlikely that it would happen. With oil companies looking to cut back on their previous loses and governments - central as well as states - aiming to generate revenue after tumultous weeks of lockdown, fuel price hikes are likely to stay till at least the end of June.
