I have lost a valued friend: PM Modi on Jaitley's death

Jerusalem, Jul 23: Merging Israel's technological expertise with India's mass production capabilities, experts from the two countries have joined hands to develop rapid testing for Covid-19 in under 30 seconds.

Israel will soon send a high-level research delegation to India to conduct a series of "final stages of testing" as part of the joint effort to develop the rapid testing kits for Covid-19 .

A high ranking team from the Directorate of Defence Research and Development (DDR&D), in the Ministry of Defense, which has been working with India's DRDO to develop rapid testing for Covid-19 in under 30 seconds, is to leave from Tel Aviv to New Delhi on a special flight in a few days, Israel's Ministry of Defence said in a statement on Thursday.

Israel's Ministry of Foreign Affairs (MFA) and Ministry of Health are also involved in this unprecedented cooperation between the two countries which aims at "merging Israeli technology with Indian development and production capabilities to allow a swift resumption of normal life alongside the virus".

The DDR&D team will conduct a series of "final stages of testing" to determine the effectiveness of a number of rapid diagnostic solutions with their Indian counterparts.

Since the start of the pandemic, the DDR&D has tested dozens of diagnostic technologies. Some of them have matured and passed initial trials in Israel, however in order to complete testing and prove their effectiveness, these must be tested on a wide range of patients, IMoD said.

The four tech systems that will be tested are - voice test, breathalyzer test based on terra-hertz waves, isothermal test, and polyamino acids test.

"What they all have in common is the ability to detect the presence of the virus in the body quickly- usually within minutes. Developing diagnostic capabilities is a goal for the State of Israel and of many additional countries around the world. It is the most effective way to cut off 'chains of infection', prevent prolonged quarantine and enable the reopening of the global economy," the statement said.

"We hope that the research and development led by the DDR&D together with our excellent industries and academic institutions, will lead to a breakthrough that will change the way we diagnose and fight the virus, while giving the boost necessary to 'restart' our economy," Defense Minister Benny Gantz said.

Foreign Minister Gabi Ashkenazi noted that this cooperation provides a unique opportunity for scientific and technological cooperation that can assist Israel, India and the world in coping both with the pandemic and with the economic crisis that came with it.

The cooperation between Israel and India will enable the delegation and its Indian counterparts, to collect tens of thousands of samples in just ten days, and analyze them using computer systems based on artificial intelligence. This massive sampling will shorten processes and advance the approval of effective technology. All tests will be validated using PCR tests.

"The cooperation between India and Israel on Covid-19 is a good example of harnessing the scientific and technological strengths that the two countries have for larger, common good. It will also further deepen our strategic ties,” India's Ambassador Sanjeev Singla told PTI.

The flight will be carrying some breakthrough emerging Israeli technologies for combatting Covid-19, which have been donated by the Israeli foreign ministry and the private sector, in order to bolster India’s response to the virus outbreak.

The plane will also deliver mechanical ventilators which were given special permission by Israel for export to India.

Prime Minister Narendra Modi and his Israeli counterpart Benjamin Netanyahu have held three telephonic conversations since the outbreak of the pandemic and promised mutual assistance in dealing with the virus, committing to joint technological and scientific research between the countries.

The Israeli media widely reported that Modi lifted a ban on the export of Hydroxychloroquine at Netanyahu's request.

"The past few years have cemented the strategic relations between India and Israel and have included two historical visits of the Prime Ministers in Israel and in India," a press statement from the ministry of defence said.

"India seeks to integrate advanced technologies in its hospitals as they prepare to treat massive waves of Covid-19 patients on an Indian scale. The Israeli companies chosen by the MFA, MOD and Israel Defence Forces to be sent to India are potentially given unique access to one of the largest economies in the world to provide monitoring and treatment technologies while significantly reducing contact between the patients and the medical staff," it said.

"By opening the door to India’s market with its development and production capabilities, these Israeli technologies can be mass produced at a lower cost and could in future be jointly exported to third countries," it said.

"The COVID-19 pandemic is a global challenge, so it is only right that the solution be a global scientific cooperation between countries. India and Israel’s military R&D cooperation is well known for its success. I have no doubt the same will be seen in the private sector joined by brilliant scientific minds from both countries to introduce a breakthrough in swift and simple testing procedures,” said Prof. Nati Keller, an infectious diseases specialist from Sheba Medical Center, who is leading the medical side of the delegation.

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, Jun 27: Fuel prices were hiked by the oil marketing companies for the 21st day in a row on Saturday. Petrol and diesel will now cost Rs 80.38/litre and Rs 80.40/litre respectively in the national capital.

The price of petrol is increased by Rs 0.25 per litre while that of diesel by Rs 0.21 per litre.
Rates differ from state to state depending on the incidence of value-added tax (VAT).

Notably, oil marketing companies have been adjusting retail rates in line with costs after an 82-day break from rate revision amidst the COVID-19 pandemic. These firms on June 7 restarted revising prices in line with costs.

The Congress party had called the increase in the price of petrol and diesel 'unjust', 'thoughtless' and demanded from the Central government to roll back increase with immediate effect and pass on the benefit of low oil prices directly to the citizens of this country.
In an official statement, the Congress Working Committee (CWC) had said that no government should levy and impose such unacceptable strain on its people.

Before the nation entered the lockdown, the average price of petrol and diesel in Delhi was Rs 69.60 per litre and Rs 62.30 per litre respectively.
