Militants attack Muslims in Central African Republic's capital

Islamabad, Feb 26: Islamabad on Tuesday declared former Prime Minister Nawaz Sharif an absconder while simultaneously denying extending bail to him.

The federal cabinet presided over by Prime Minister Imran Khan, cited that Sharif failed to provide required medical reports and has violated the bail terms.

The government has also decided to freeze gas and electricity tariffs for the next four months, The Dawn reported.

"After Nawaz Sharif failed to submit his medical report of any hospital in London, the medical board rejected a medical certificate sent by him and [the government] declared him an absconder. From today, Nawaz Sharif is an absconder according to the law of land and if he does not return to the country he will be declared a proclaimed offender," said Dr Firdous Ashiq Awan, Special Assistant to the Prime Minister on Information, in a press conference.

She further asserted that the Punjab government, which was authorized by the Islamabad High Court (IHC) to decide Sharif's case on medical grounds, had written several letters asking him to submit his medical report from any hospital in London. However, he failed to do so and only sent a certificate that was not accepted by the medical board.

"If he (Nawaz Sharif) is seriously ill then why a comprehensive medical report is not being submitted to the medical board," Firdous added.

Further, she said that the office of the opposition leader was also waiting for his younger brother and Leader of the Opposition in the National Assembly Shahbaz Sharif, who was also staying in London for 'no reason'.

"He is getting a monthly salary and enjoying luxurious offices and other perks and privileges but not performing his duties required by his office and the people. Shahbaz Sahib, return to the country and justify your salary and other benefits being given from taxpayers' money," Firdous added.

On October 29 last year, the IHC granted bail for eight weeks to Sharif, who was convicted and disqualified in corruption cases, on medical grounds.

Sharif left Pakistan for London along with Shahbaz on November 19, 2019, for his medical treatments there.

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.

Moscow, Jan 16: Russia's government resigned in a shock announcement on Wednesday after President Vladimir Putin proposed a series of constitutional reforms.

In a televised meeting with the Russian president, Prime Minister Dmitry Medvedev said the proposals would make significant changes to the country's balance of power and so "the government in its current form has resigned".

"We should provide the president of our country with the possibility to take all the necessary measures" to carry out the changes, Medvedev said.

"All further decisions will be taken by the president." Putin asked Medvedev, his longtime ally, to continue as head of government until a new government has been appointed.

"I want to thank you for everything that has been done, to express satisfaction with the results that have been achieved," Putin said.

"Not everything worked out, but everything never works out." He also proposed creating the post of deputy head of the Security Council, suggesting that Medvedev take on the position.

Earlier Wednesday Putin proposed a referendum on a package of reforms to Russia's constitution that would strengthen the role of parliament.

The changes would include giving parliament the power to choose the prime minister and senior cabinet members, instead of the president as in the current system.
