Modi tries to woo Dalits in Karnataka, says he is trying to fulfil Ambedkar’s dream

The current physical distancing guidelines provided by the World Health Organisation (WHO) and by the US Centers for Disease Control and Prevention (CDC) may not be adequate to curb the coronavirus spread, according to a research which says the gas cloud from a cough or sneeze may help virus particles travel up to 8 metres. The research, published in the Journal of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.

Study author, MIT associate professor Lydia Bourouiba, warned that droplets of all sizes can travel 23 to 27 feet, or 7-8 metres, carrying the pathogen.

According to Bourouiba, the current guidelines are based on "arbitrary" assumptions of droplet size, "overly simplified", and "may limit the effectiveness of the proposed interventions" against the deadly pandemic.

 She explained that the old guidelines assume droplets to be one of two categories, small or large, taking short-range semi-ballistic trajectories when a person exhales, coughs, or sneezes.

However based on more recent discoveries, the MIT scientist said, sneezes and coughs are made of a puff cloud that carries ambient air, transporting within it clusters of droplets of a wide range of sizes.

Bourouiba warned that this puff cloud, with ambient air entrapped in it, can offer the droplets moisture and warmth that can prevent it from evaporation in the outer environment.

"The locally moist and warm atmosphere within the turbulent gas cloud allows the contained droplets to evade evaporation for much longer than occurs with isolated droplets," she said.

"Under these conditions, the lifetime of a droplet could be considerably extended by a factor of up to 1000, from a fraction of a second to minutes," the researcher explained in the study.

The MIT scientist, who has researched the dynamics of coughs and sneezes for years, added that these droplets settle along the trajectory of a cough or sneeze contaminating surfaces, with their residues staying suspended in the air for hours.

"Even when maximum containment policies were enforced, the rapid international spread of COVID-19 suggests that using arbitrary droplet size cutoffs may not accurately reflect what actually occurs with respiratory emissions, possibly contributing to the ineffectiveness of some procedures used to limit the spread of respiratory disease," Bourouiba wrote in the study

Riyadh, Apr 22: In an extraordinary initiative, the government of the Kingdom of Saudi Arabia has decided to facilitate the travel of expatriates who have an exit and reentry visa or final exit visa to return to their countries.

This is in line with the order of Custodian of the Two Holy Mosques King Salman, according to the Saudi Press Agency.

According to the initiative, called “Auda” (return), expatriates can apply seeking permission for travel to their countries through the Absher portal of the ministry.

Announcing this, Saudi's Ministry of Interior said that the initiative will be implemented in cooperation with a number of relevant government agencies.

Requests for travel from expatriates will be received and approved in coordination with the relevant authorities to complete their travel procedures on board international flights.

As per the initiative, a text message will be sent to the beneficiary stating the travel date, ticket number and reservation details, and by which the beneficiary can obtain his travel ticket and complete the travel procedures.

Clarifying the procedures for the travel, the ministry said that the applicant shall select the icon (Auda) after visiting the Absher portal and fill the following fields: iqama (residency permit) number, date of birth, mobile number, departure city and airport of arrival.

It is not mandatory for the expatriate to have his own Absher account for availing of the service, the ministry said, adding that this facility is to enable expatriates to benefit from this initiative.

The departure will be through the following airports: King Khalid International Airport in Riyadh, King Abdulaziz International Airport in Jeddah, Prince Muhammad International Airport in Madinah, and King Fahd International Airport in Dammam.

Those expatriates who are outside these cities can benefit from the service through entering airport of departure after completion of their travel procedures in sufficient period of time.

Bengaluru, May 12: Former chief minister and senior Congress leader Siddaramaiah on Tuesday said that the Central and Karnataka government have failed in containing the coronavirus spread despite having enough time for preparations.

"Central and state government failed in properly controlling COVID-19. The first coronavirus case was reported in Kerala on January 30. Lockdown was imposed on March 24. Both Centre and state had enough time for preparations," Siddaramaiah said in a press meet here.

He said that the Central government did not stop the airline services on time.

"Karnataka government might have been able to stop COVID-19 properly. However, both the state and central government are playing politics over the issue and blaming Tablighi Jamaat for the spread, which is a political strategy painted by the RSS," Siddaramaiah said.

"Who gave the licence to Tablighi's international convention? Who gave them permission in Delhi? They didn't control it. Central government is directly responsible for the increasing numbers of COVID-19 cases in India," he added.

Siddaramaiah said that the lockdown was imposed without any preparation, which he said caused huge problems for the migrant workers across the country.

"Now, the government is collecting ticket fare and looting migrant workers. They don't have jobs or food, they don't have money, and they earn every day to survive. How will they pay for the tickets? Why the government is not arranging for free trains?" the Congress leader said.

He said that around Rs 35,000 crore have been credited to PM CARES fund, Rs 3,000 crore of which was credited from Karnataka alone. "Why are they not using that money?" he asked.

Siddaramaiah said that the party is demanding for the Centre to arrange for migrant workers to return to their native places across the country free of cost.

"We asked Chief Minister to call an all party meeting. We gave many suggestions, which this government did not consider. We also took a delegation and gave a memorandum about farmers, daily wage workers, road side vendors, barbers, problems faced by the unorganized sector. But this government didn't consider any of it," he said.

Questioning the Central government's suggestion to States to amend their Agricultural Produce Market Committee (APMC) Acts, Siddaramaiah said that the move is against the federal system of the country and claimed that it harms the interests of small scale farmers.

He said that the BJP-led state government has also decided to postpone the Gram panchayat elections in the state and is trying to nominate their party workers for village panchayat elections.

"The Government must continue with the present members of the Gram panchayat. If BJP tries to nominate their party members to village panchayats, we will take to streets to protest despite the lockdown," Siddaramaiah added.
