'5 to 7 Million People from Airport to Ahmedabad Stadium': Before India Visit, Trump Reveals Modi's Promise

New Delhi, Jan 17: Airports in Srinagar and Jammu are to be “immediately” brought under the security cover of the CISF in view of the arrest of DSP Davinder Singh, a Jammu and Kashmir government order has said.

The two sensitive airports are to be “handed over” to the CISF by January 31, the order of the Jammu and Kashmir Home Department to the Director General of Police (DGP) said.

“This issue (CISF security at Srinagar and Jammu airports) has acquired immediacy in view of the recent developments relating to the arrest of Davinder Singh, DSP airport security, for trying to assist militants to travel to other parts of the country,” the order issued on Wednesday said.

Police had arrested Singh, a deputy superintendent of police, at Mir Bazar in Jammu and Kashmir’s Kulgam district on Saturday, along with Hizbul Mujahideen terrorists Naveed Baba and Altaf, besides a lawyer who was operating as an overground worker for terror outfits.

The two airports are guarded by the CRPF and the J-K Police at present.

The Union government had last year decided that the Central Industrial Security Force (CISF) will be handed over security of these two airports along with the one in Leh in view of their sensitive and strategic location and the threats it faced related to possible terrorist and hijack attempts.

CISF is the national civil aviation security force and at present it guards 61 airports including the ones at Delhi and Mumbai.

News agency had on January 13 reported that the Union home ministry sanctioned about 800 personnel to the CISF in order to take over security duties at the three airports of the newly created Union Territories of Jammu and Kashmir and Ladakh.

As per the original plan, the CISF was to take over Jammu airport by next month and the Srinagar and Leh airports after the spell of severe cold ends.

However, officials said, keeping in mind the arrest of the DSP and his alleged links, the latest order has been issued which also directs the J-K Police to make arrangements for accommodation, transport and other logistical requirements of the armed contingent of the CISF on a quick basis.

Once inducted at the most-sensitive Srinagar airport, the CISF will secure access control at both city and air side (tarmac area) while the CRPF will be responsible for securing the outer periphery. At the Jammu airport, the peripheral security duties will be rendered by the JK Police.

An assortment of surveillance and security gadgets like CCTVs, observation monitors, hand-held metal detectors, bullet-proof patrol vehicles and bomb detection and disposal equipment are also being provided by the airport operator, the Airports Authority of India (AAI), to the CISF.

The Union government sometime back made it clear that CISF will be the only civil airports guarding force and all such facilities in the country will be gradually brought under its command to bolster aviation security and tighten anti-terror and anti-hijack protocols.

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, Feb 16: Aam Aadmi Party (AAP) national convener Arvind Kejriwal was on Sunday sworn-in as the Chief Minister of Delhi for the third time in a row at Ramlila Maidan here, after his party registered a massive victory in the recently concluded Delhi Assembly polls.

Kejriwal was administered the oath of office and secrecy by Delhi Lieutenant Governor Anil Baijal.

The sprawling Ramlila Maidan reverberated with sounds of thousands of people cheering for the AAP leader.

Kejriwal who received a hero's welcome here had extended an invitation to the people of Delhi urging them to attend the swearing-in ceremony to witness "the son of Delhi" taking oath today.

The AAP nearly repeated its 2015 performance in the elections, sweeping the Assembly polls winning 62 seats in the 70-member Assembly, in the face of a high-voltage campaign by the BJP, which fielded a battery of Union Ministers and Chief Ministers in its electioneering spearheaded by Home Minister Amit Shah.
