Search for Malaysian plane may extend to Indian Ocean: US

March 14, 2014

Malaysian_plane_mysteryKuala Lumpur/Washington, Mar 14: A new search area for Malaysia Airlines Flight 370 may be opened in the Indian Ocean, the White House said, significantly broadening the potential location of the plane, which disappeared nearly a week ago with 239 people on board.

Expanding the search area to the Indian Ocean would be consistent with the theory that the Boeing 777 may have detoured to the west about an hour after take-off from the Malaysian capital Kuala Lumpur en route to Beijing.

"It's my understanding that based on some new information that's not necessarily conclusive — but new information — an additional search area may be opened in the Indian Ocean," White House spokesman Jay Carney told reporters in Washington.

Carney did not specify the nature of the new information and Malaysian officials were not immediately available to comment.

The disappearance of the Malaysia Airlines plane is one of the most baffling mysteries in the history of modern aviation. There has been no trace of the plane nor any sign of wreckage despite a search by the navies and military aircraft of more than a dozen countries across Southeast Asia.

Satellites picked up faint electronic pulses from the aircraft after it went missing on Saturday, but the signals gave no information about where the jet was heading and little else about its fate, two sources close to the investigation said on Thursday.

But the "pings" indicated its maintenance troubleshooting systems were switched on and ready to communicate with satellites, showing the aircraft was at least capable of communicating after losing touch with air traffic controllers.

The system transmits such pings about once an hour, according to the sources, who said five or six were heard. However, the pings alone are not proof that the plane was in the air or on the ground, the sources said.

Malaysian authorities have said the last civilian contact occurred as the Boeing 777-200ER flew north into the Gulf of Thailand. They said military radar sightings indicated it may have turned sharply to the west and crossed the Malay Peninsula toward the Andaman Sea.

The new information about signals heard by satellites shed little light on the mystery of what happened to the plane, whether it was a technical failure, a hijacking or another kind of incident on board.

While the troubleshooting systems were functioning, no data links were opened, the sources said, because the companies involved had not subscribed to that level of service from the satellite operator, the sources said.

Boeing and Rolls-Royce, which supplied its Trent engines, declined to comment.

Earlier Malaysian officials denied reports that the aircraft had continued to send technical data and said there was no evidence that it flew for hours after losing contact with air traffic controllers early last Saturday.

"It's extraordinary that with all the technology that we've got that an aircraft can disappear like this," Tony Tyler, the head of the International Air Transport Association that links over 90 percent of the world's airlines, told reporters in London.

MILITARY DEPLOYMENT GROWS

Ships and aircraft are now combing a vast area that had already been widened to cover both sides of the Malay Peninsula and the Andaman Sea.

The US Navy was sending an advanced P-8A Poseidon plane to help search the Strait of Malacca, separating the Malay Peninsula from the Indonesian island of Sumatra. It had already deployed a Navy P-3 Orion aircraft to those waters.

US defense officials told Reuters that the US Navy guided-missile destroyer, USS Kidd, was heading to the Strait of Malacca, answering a request from the Malaysian government. The Kidd had been searching the areas south of the Gulf of Thailand, along with the destroyer USS Pinckney.

India's defence ministry has ordered the deployment of ships, aircraft and helicopters from the remote Andaman and Nicobar Islands, at the juncture of the Bay of Bengal and the Andaman Sea. An Indian P8I Poseidon surveillance plane was sent to the Andaman islands on Thursday.

China, which had more than 150 citizens on board the missing plane, has deployed four warships, four coastguard vessels, eight aircraft and trained 10 satellites on a wide search area. Chinese media have described the ship deployment as the largest Chinese rescue fleet ever assembled.

WRONG IMAGES

On the sixth day of the search, planes scanned an area of sea where Chinese satellite images had shown what could be debris but found no sign of the airliner.

Malaysian transport minister Hishammuddin Hussein told a news conference the images were provided accidentally, saying the Chinese government neither authorized nor endorsed putting them on a website. "The image is not confirmed to be connected to the plane," he said.

It was the latest in a series of contradictory reports, adding to the confusion and agony of the relatives of the passengers.

As frustration mounted over the failure to find any trace of the plane, China heaped pressure on Malaysia to improve coordination in the search.

Premier Li Keqiang, speaking at a news conference in Beijing, demanded that the "relevant party" step up coordination while China's civil aviation chief said he wanted a "smoother" flow of information from Malaysia, which has come under heavy criticism for its handling of the disaster.

Malaysian police have said they were investigating whether any passengers or crew on the plane had personal or psychological problems that might shed light on the mystery, along with the possibility of a hijacking, sabotage or mechanical failure.

The Boeing 777 has one of the best safety records of any commercial aircraft in service. Its only previous fatal crash came on July 6 last year when Asiana Airlines Flight 214 struck a seawall with its undercarriage on landing in San Francisco, killing three people.

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.

Islamabad, Feb 17: Prime Minister Imran Khan on Monday warned that Pakistan may face another refugee crisis if the international community failed to take notice of the current situation in India.

Speaking at the two-day refugee summit in Islamabad on 40 years of hosting Afghan refugees in Pakistan, he said India’s "ultranationalist ideology going unchecked could lead to destruction and the region could become a flashpoint", The Express Tribune quoted him as saying.

Khan said if the international community does not take notice of this situation, it will create another refugee crisis for Pakistan as Muslims of India will move to Pakistan.

"This is not the India of Jawaharlal Nehru and Mahatma Gandhi. The United Nations (UN) must play its role otherwise it will become a very big problem in the future," Duniya News quoted Khan as saying.

He said said that Prime Minister Narendra Modi’s statement that India can destroy Pakistan in 11 days is not a responsible statement by a premier of a nuclear state with a huge population, the paper reported.

Khan made the statement in the presence of visiting UN Secretary General Antonio Guterres, who was also attending the summit.

He said because of the "Hindutva" ideology, Kashmiris have been lockdown for over 200 days. He alleged under the same ideology, the BJP-led government passed two discriminatory nationalistic legislations, targeting 200 million Muslims in India.

Khan was referring to India's Citizenship (Amendment) Act and the revocation of the special status to Jammu and Kashmir.

The new citizenship law passed by the Indian Parliament in December 2019 offers citizenship to non-Muslim persecuted religious minorities from Pakistan, Bangladesh and Afghanistan.

The Indian government has maintained that the CAA is an internal matter of the country and stressed that the goal is to protect the oppressed minorities of neighbouring countries.

India revoked Jammu and Kashmir's special status on August 5. Reacting to India's move, Pakistan downgraded diplomatic ties with New Delhi and expelled the Indian High Commissioner.

India has always maintained that Jammu and Kashmir is its integral part and ruled out any third party mediation, including either from the UN or the US, saying it is a bilateral issue with Pakistan.

Melbourne, Apr 10: Scientists have identified six drug candidates from more than 10,000 compounds that may help treat COVID-19.

The research, published in the journal Nature, tested the efficacy of approved drugs, drug candidates in clinical trials and other compounds.

"Currently there are no targeted therapeutics or effective treatment options for COVID-19," said Professor Luke Guddat from the University of Queensland in Australia.

"In order to rapidly discover lead compounds for clinical use, we initiated a programme of high-throughput drug screening, both in laboratories and also using the latest computer software to predict how different drugs bind to the virus," Guddat said.

The project targeted the main COVID-19 virus enzyme, known as the main protease or Mpro, which plays a pivotal role in mediating viral replication, the researchers said.

This makes it an attractive drug target for this virus, and as people don't naturally have this enzyme, compounds that target it are likely to have low toxicity, they said.

"We add the drugs directly to the enzyme or to cell cultures growing the virus and assess how much of each compound is required to stop the enzyme from working or to kill the virus. If the amount is small, then we have a promising compound for further studies," said Guddat.

After assaying thousands of drugs, researchers found of the six that appear to be effective in inhibiting the enzyme, one is of particular interest.

"We're particularly looking at several leads that have been subjected to clinical trials including for the prevention and treatment of various disorders such as cardiovascular diseases, arthritis, stroke, atherosclerosis and cancer," Guddat said.

Researchers said compounds that are already along the pipeline to drug discovery are preferred, as they can be further tested as antivirals at an accelerated rate compared to new drug leads that would have to go through this process from scratch.

"With continued and up-scaled efforts we are optimistic that new candidates can enter the COVID-19 drug discovery pipeline in the near future," Guddat said.
