Faithful begin Hajj pilgrimage under strict Covid-19 measures

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.

New Delhi, Feb 23: Hailing the role of first Prime Minister Jawaharlal Nehru in shaping India a modern nation state, former Prime Minister Manmohan Singh on Saturday hit out at the Narendra Modi-led Central government, saying "nationalism" and the slogan of 'Bharat Mata Ki Jai' are being misused to construct a militant and purely emotional idea of India.

Speaking at the launch of a book on Jawaharlal Nehru's works and speeches, Singh said: "I am extremely happy that this book makes an effort to revisit Pandit Nehru. He had led this country in its volatile, formative days when we adopted democratic way of life, accommodating divergent social and political views."

The former Prime Minister said that Nehru, who was very proud of Indian heritage, "assimilated it", and harmonised them into the needs of a "new modern" India.

"A great visionary, Nehruji laid the foundation for shaping India as a modern nation state," he said.

Highlighting the works of the first Prime Minister, Singh said: "If India is recognized in the comity of nations as a vibrant democracy and, if it is considered as one of the important world powers, it was Nehru, who should be recognised as its main architect."

He said Nehru was not only a statesman of high international standing, but a great historian and literary figure too.

"With an inimitable style, and a multi-linguist, Nehru laid the foundation of the universities, academies and cultural institutions of Modern India. But for Nehru's leadership, Independent India would not have become what it is today," he said.

Taking an apparent dig at the BJP government, he said: "But unfortunately, a section of people who either do not have the patience to read history or would like to be deliberately guided by their prejudices, try their best to picture Nehru in a false light.

"But I am sure, history has a capacity to reject fake and false insinuations and put everything in proper perspective," he said.

He said the book "Who is Bharat Mata" is such an attempt to set the narrative in the right direction.

Singh said that selecting appropriate pieces from Nehruji's works, the book justifies its title "Who is Bharat Mata?"

"As this book contains a timely collection of writings by and on Pandit Jawaharlal Nehru- the leader, who shaped India and the Icon whose legacy is the subject of intense and often angry reaction today.

The book also comprises reminiscences and assessments of Nehru by some of his contemporaries and near contemporaries-among them, including Mahatma Gandhi, Bhagat Singh, Sardar Patel, Maulana Azad, Aruna Asaf Ali, Sheikh Abdullah, Ramdhari Singh Dinkar, Ali Sardar Jafri, Baldev Singh, Martin Luther King Jr, Richard Attenborough, Lee Kuan Yew and Atal Bihari Vajpayee.

"It is a book of particular relevance at a time when nationalism and the slogan of ‘Bharat Mata Ki Jai' are being misused to construct a militant and purely emotional idea of India that excludes millions of residents and citizens," Singh said attacking the BJP government.

The two time Prime Minister further said that in the pages of the carefully complied anthology-which also carries illuminating introductions by the authors Nehru emerges as a "remarkable man of ideas and action", who had an instinctive understanding of India's civilisational spirit and as a visionary with clear commitment to the promotion of scientific temper, who despite the compulsions of politics, remained a true democrat.

"His legacy continues to be of immense significance-perhaps more today than at any other time in our history," he said.

He also warned that "Nehru makes a very significant and time relevant remark on the dangers of leaderships falling into a trap and getting removed far away from the common people whom they are supposed to serve".

"In an atmosphere, when emotions are deliberately get provoked and the gullible are misled by false propaganda, misusing communication technology, this book makes a refreshing break through," Singh added.

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.
