Jammu, Jan 18: Prepaid mobile connections were restored in Jammu and Kashmir on Saturday and 2G services resumed in two districts of the valley after being disconnected on August 5 last year. Voice and SMS facilities were restored for all local prepaid mobile phones across the Union territory.

Rohit Kansal, the principal secretary to the administration of Jammu and Kashmir said the order will come into effect from Saturday.

In order to consider giving mobile Internet connectivity on such SIM cards, the telecom service providers will have to verify the credentials of the subscribers, he said.

Internet service providers have been asked to provide fixed line Internet connectivity in all the 10 districts of Jammu region and two districts, Kupwara and Bandipora, in North Kashmir.

Telecom services were shut in the entire Jammu and Kashmir on August 5 when the Centre abrogated special status to the erstwhile state and also bifurcated it into two Union Territories.

However, the Supreme Court came down heavily on the UT administration last week for arbitrarily shutting down the Internet, the facility described as the fundamental right by the apex court.

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.

New Delhi, May 7: Air India has opened bookings for eligible foreign nationals and valid visa holders of the UK, the USA and Singapore for outbound repatriation flights that will be operated between May 7 and May 14 under the Vande Bharat mission, officials said.

Foreign nationals or valid visa holders will be charged the same fare as Indian nationals who want a seat on the inbound repatriation flights, they said.

For all flights between India and the USA under the Vande Bharat mission, Air India is charging a fixed fare of Rs 1 lakh per passenger.

For flights between India and Singapore, the charge is Rs 18,000-20,000 per passenger, and it is Rs 50,000 per person for India-UK flights.

On Tuesday, the Ministry of Home Affairs had clarified that a person who has an Overseas Indian Citizenship (OCI) card, or citizenship of a foreign country, or a valid visa of more than one year of that country, or the green card of that country can travel on repatriation flights leaving India under the Vande Bharat mission.

Air India will be conducting 64 flights to 12 countries between May 7 and May 13 to bring back approximately 15,000 Indians stranded due to the coronavirus-induced lockdown, Civil Aviation Minister Hardeep Singh Puri had announced on Tuesday.

However, some flights have been delayed and therefore, this set of 64 flights will be operated between May 7 and May 14, the airline officials said.

On Wednesday, an Indian businessman and his cook landed at Delhi airport from Lusaka in Zambia in a plane that was supposed to come without any passengers, senior government officials said.

The private chartered aircraft was scheduled to come empty and take around 40 Zambian nationals to Lusaka in a repatriation flight, they added.

"We had not permitted any incoming passengers. We will seek explanation from the airline (private operator) as to how it happened. BOI (Bureau of Immigration) has a very stringent protocol for dealing with such deviations, which must have been acted upon," said a senior official of aviation regulator DGCA.

It is not clear if the businessman and his cook were deported or sent to a quarantine facility within India.

India has been under a lockdown since March 25 to curb the spread of the novel coronavirus. All scheduled commercial passenger flights have been suspended during the lockdown.

However, cargo flights, medical evacuation flights and special flights permitted by Directorate General of Civil Aviation (DGCA) have been allowed to operate during this time.
