Demolish Delhi Jama Masjid, hang me if idols are not found: Sakshi Maharaj

New Delhi, Jul 22: With a spike of 37,724 cases and 648 deaths reported in the last 24 hours, the total number of COVID-19 cases in India stands at 11,92,915, according to the Union Ministry of Health and Family Welfare.

The total number of cases includes 4,11,133 active cases, 7,53,050 cured/discharged/migrated and 28,732 deaths, the Health Ministry informed.

Maharashtra remains the worst affected state with 3,27,031 cases and 12,276 deaths.
The second worst-hit state, Tamil Nadu has reported 1,80,643 COVID-19 cases so far while Delhi has reported 1,25,096 cases, according to the Ministry.

Other states that have witnessed a higher number of COVID-19 positive cases include, Andhra Pradesh with 58,668 cases, Karnataka with 71,069 while Telangana has reported 47,705 COVID-19 positive cases.

Meanwhile, as per the information provided by the Indian Council of Medical Research (ICMR), the total number of samples tested up to July 21 is 1,47,24, 546 including 3,43,243 samples tested yesterday.

Jan 27: The Andhra Pradesh Cabinet passed a resolution on Monday setting in motion the process for abolishing the state Legislative Council.

A similar resolution will now be adopted in the Legislative Assembly and sent to the Centre for necessary follow-up action.

With just nine members, the ruling YSR Congress is in minority in the 58-member Legislative Council. The opposition Telugu Desam Party (TDP) has an upper hand with 28 members and the ruling party could get a majority in the House only in 2021 when a number of opposition members will retire at the end of their six-year term.

The move by the Andhra Pradesh cabinet came after the Y S Jaganmohan Reddy government last week failed to pass in the Upper House of the state legislature two crucial Bills related to its plan of having three capitals for the state.

Andhra Pradesh Legislative Council Chairman M A Sharrif on January 22 referred to a select committee the two bills -- AP Decentralisation and Inclusive Development of All Regions Bill, 2020, and the AP Capital Region Development Authority (CRDA) Act (Repeal) Bill -- for deeper examination.

The chairman had said that he was using his discretionary powers under Rule 154 while referring the Bills to the select panel in line with the demand of the TDP.

Following this, the chief minister had told the Assembly, "We need to seriously think whether we need to have such a House which appears to be functioning with only political motives. It is not mandatory to have the Council, which is our own creation, and it is only for our convenience."

"So let us discuss the issue further on Monday and take a decision on whether or not to continue the Council," he had said.

In fact, the YSRC had on December 17 first threatened to abolish the Council when it became clear that the TDP was bent on blocking two Bills related to creation of a separate Commission for SCs and conversion of all government schools into English medium.

As the Legislature was adjourned sine dine on December 17, no further action was taken. But last week, the issue cropped up again as the TDP remained firm on its stand on opposing the three-capitals plan.

The YSRC managed to get two TDP members to its side, but the government failed to get the three capitals Bills passed in the Council.

"What will be the meaning of governance if the House of Elders does not allow good decisions to be taken in the interest of people and block enactment of laws? We need to seriously think about it… Whether we should have such a House or do away with it," the chief minister had said in the Assembly.

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.
