Goa deputy speaker slams government for failing to check cow vigilantes

New Delhi, Jan 29: The Supreme Court on Wednesday dismissed the plea by Mukesh Kumar Singh, one of the four death row convicts in the Nirbhaya gang rape and murder case, challenging the rejection of his mercy petition by the President.

A three-judge bench headed by Justice R Banumathi said that expeditious disposal of mercy plea by the President doesn't mean non-application of mind by him.

The court also said that alleged sufferings in prison can't be grounds to challenge the rejection of mercy petition.

The bench said all relevant material including judgments pronounced by trial court, high court and Supreme Court were placed before the President when he was considering the mercy plea of the convict.

The bench also comprising justices Ashok Bhushan and A S Bopanna rejected the contentions of the counsel appearing for Singh that entire materials of the case were not placed before the President when he was considering his mercy plea.

The bench, while referring to two files placed before it by the Centre on Tuesday, said that as per the January 15 covering letter which was sent by the Delhi government to the Ministry of Home Affairs, all relevant documents were sent.

The bench noted that detailed judgements of trial court, high court and the Supreme Court, curative petition filed by Singh, his past criminal history and his family background were sent to the Home Ministry by the Delhi government.

"All the documents were taken into consideration by the President while rejecting the mercy petition," the bench said.

The bench also dealt with submissions advanced by the convict's counsel, who had argued that the mercy plea was rejected at "lightning speed".

The bench said that if a mercy petition is expeditiously dealt with, it cannot be assumed that it has been adjudicated upon in a pre-conceived mind.

London, May 20: The current physical distancing guidelines of 6 feet may be insufficient to prevent COVID-19 transmission, according to a study which says a mild cough in low wind speeds can propel saliva droplets by as much as 18 feet.

Researchers, including those from the University of Nicosia in Cyprus, said a good baseline for studying the airborne transmission of viruses, like the one behind the COVID-19 pandemic, is a deeper understanding of how particles travel through the air when people cough.

In the study, published in the journal Physics of Fluids, they said even with a slight breeze of about four kilometres per hour (kph), saliva travels 18 feet in 5 seconds.

"The droplet cloud will affect both adults and children of different heights," said study co-author Dimitris Drikakis from the University of Nicosia.

According to the scientists, shorter adults and children could be at higher risk if they are located within the trajectory of the saliva droplets.

They said saliva is a complex fluid, which travels suspended in a bulk of surrounding air released by a cough, adding that many factors affect how saliva droplets travel in the air.

These factors, the study noted, include the size and number of droplets, how they interact with one another and the surrounding air as they disperse and evaporate, how heat and mass are transferred, and the humidity and temperature of the surrounding air.

In the study, the scientists created a computer simulation to examine the state of every saliva droplet moving through the air in front of a coughing person.

The model considered the effects of humidity, dispersion force, interactions of molecules of saliva and air, and how the droplets change from liquid to vapour and evaporate, along with a grid representing the space in front of a coughing person.

Each grid, the scientists said, holds information about variables like pressure, fluid velocity, temperature, droplet mass, and droplet position.

The study analysed the fates of nearly 1,008 simulated saliva droplets, and solved as many as 3.7 million equations.

"The purpose of the mathematical modelling and simulation is to take into account all the real coupling or interaction mechanisms that may take place between the main bulk fluid flow and the saliva droplets, and between the saliva droplets themselves," explained Talib Dbouk, another co-author of the study.

However, the researchers added that further studies are needed to determine the effect of ground surface temperature on the behaviour of saliva in air.

They also believe that indoor environments, especially ones with air conditioning, may significantly affect the particle movement through air.

This work is important since it concerns safety distance guidelines, and advances the understanding of the transmission of airborne diseases, Drikakis said.

Dubai/Washington, Jan 6: Tens of thousands of Iranians thronged the streets of Tehran on Monday for the funeral of Quds Force commander Qassim Suleimani who was killed in a US air strike last week and his daughter said his death would bring a "dark day" for the United States.

"Crazy Trump, don't think that everything is over with my father's martyrdom," Zeinab Suleimani said in her address broadcast on state television after US President Donald Trump ordered Friday's strike that killed the top Iranian general.

Iran has promised to avenge the killing of Qassim Suleimani, the architect of Iran's drive to extend its influence across the region and a national hero among many Iranians, even many of those who did not consider themselves devoted supporters of the Islamic Republic's clerical rulers.

The scale of the crowds in Tehran shown on television mirrored the masses that gathered in 1989 for the funeral of the founder of the Islamic Republic, Ayatollah Ruhollah Khomeini.

In response to Iran's warnings, Trump has threatened to hit 52 Iranian sites, including cultural targets, if Tehran attacks Americans or US assets, deepening a crisis that has heightened fears of a major Middle East conflagration.

The coffins of the Iranian general and Iraqi militia leader Abu Mahdi al-Muhandis, who was also killed in Friday's attack on Baghdad airport, were passed across the heads of mourners massed in central Tehran, many of them chanting "Death to America".

One of the Islamic Republic's major regional goals, namely to drive US forces out of neighbouring Iraq, came a step closer on Sunday when the Iraqi parliament backed a recommendation by the prime minister for all foreign troops to be ordered out.

"Despite the internal and external difficulties that we might face, it remains best for Iraq on principle and practically," said Iraqi caretaker Prime Minister Adel Abdul Mahdi, who resigned in November amid anti-government protests.

Iraq's rival Shi'ite leaders, including ones opposed to Iranian influence, have united since Friday's attack in calling for the expulsion of US troops.

Esmail Qaani, the new head of the Quds Force, the Revolutionary Guards' unit in charge of activities abroad, said Iran would continue Suleimani's path and said "the only compensation for us would be to remove America from the region."

ALLIES AT FUNERAL

Prayers at Suleimani's funeral in Tehran, which will later move to his southern home city of Kerman, were led by Iran's Supreme Leader Ayatollah Ali Khamenei. Suleimani was widely seen as the second most powerful figure in Iran behind Khamenei.

The funeral was attended by some of Iran's allies in the region, including Ismail Haniyeh, the leader of Palestinian group Hamas who said: "I declare that the martyred commander Suleimani is a martyr of Jerusalem."

Adding to tensions, Iran said it was taking another step back from commitments under a 2015 nuclear deal with six major powers, a pact from which the United States withdrew in 2018.

Washington has since imposed tough sanctions on Iran, describing its policy as "maximum pressure" and saying it wanted to drive down Iranian oil exports - the main source of government revenues - to zero.

Talking to reporters aboard Air Force One on the way to Washington from Florida on Sunday, Trump stood by his remarks to include cultural sites on his list of potential targets, despite drawing criticism from US politicians.

"They're allowed to kill our people. They're allowed to torture and maim our people. They're allowed to use roadside bombs and blow up our people. And we're not allowed to touch their cultural sites? It doesn't work that way," Trump said.

Democratic critics of the Republican president have said Trump was reckless in authorizing the strike, and some said his comments about targeting cultural sites amounted to threats to commit war crimes. Many asked why Soleimani, long seen as a threat by US authorities, had to be killed now.

Republicans in the US Congress have generally backed Trump's move.

Trump also threatened sanctions against Iraq and said that if US troops were required to leave the country, Iraq's government would have to pay Washington for the cost of a "very extraordinarily expensive" air base there.

He said if Iraq asked US forces to leave on an unfriendly basis, "we will charge them sanctions like they've never seen before ever. It'll make Iranian sanctions look somewhat tame."
