N. Korea begins dismantling rocket test site: analysts

Hong Kong, Apr 20: Oil prices collapsed to more than two-decade lows Monday as traders grow concerned that storage facilities are reaching their limits, while equities were mixed, with some support coming from signs that the coronavirus may have peaked in Europe and the United States.

US crude benchmark West Texas Intermediate briefly plunged almost 20 percent to below 15 -- its lowest since 1999 -- as stockpiles continue to build owing to a crash in demand caused by the COVID-19 pandemic.

Analysts said this month's agreement between top producers to slash output by 10 million barrels a day was having little impact on the oil crisis because of lockdowns and travel restrictions that are keeping billions of people at home.

WTI was hit particularly hard as its main US storage facilities in Cushing, Oklahoma, were filling up.

ANZ said "crude oil prices remained under pressure, as projections of weaker demand weigh on sentiment".

"Despite the OPEC+ alliance agreeing to an unprecedented cut in output, the physical market is awash with oil," it said, referring to the Organization of the Petroleum Exporting Countries and non-OPEC partners.

And AxiCorp's Stephen Innes added: "It's a dump at all cost as no one... wants delivery of oil, with Cushing storage facilities filling by the minute.

"It hasn't taken long for the market to recognise that the OPEC+ deal will not, in its present form, be enough to balance oil markets." Stock traders were in slightly more buoyant mood as governments start to consider how and when to ease lockdowns that have crippled the global economy.

Italy, Spain, France and Britain reported drops in daily death tolls and slowing infection rates.

"We are scoring points against the epidemic," said Prime Minister Edouard Philippe, while insisting "we are not out of the health crisis yet".

Meanwhile, in the US, Andrew Cuomo, governor of badly hit New York state, said the disease was "on the descent", though he cautioned it was "no time to get cocky".

Mounting evidence suggests that the lockdowns and social distancing are slowing the spread of the virus.

That has intensified planning in many countries to begin loosening curbs on movement and easing the crushing pressure on national economies.

Adding to the sense of hope was a report indicating promising research on a drug to treat coronavirus.

Hong Kong, Shanghai and Seoul were each up 0.1 percent, while Wellington added 0.4 percent.

However, Tokyo went into the break 0.9 percent lower, while Sydney and Manila dropped one percent apiece. There were also losses in Taipei, Singapore and Jakarta.

"The longer investors have to contemplate future economic issues while they wait for more countries to be on the downward slope of the pandemic curve, the more scope there is of risk assets pricing in a difficult future," Chris Iggo, of AXA Investment Managers UK, said.

Investors are keeping an eye on Washington, where Congress and the White House are working towards a 450 billion economic relief plan for small business to add to the trillions already pledged to support the economy.

Big-name companies including IBM, Netflix and Coca-Cola are due to deliver their earnings reports.

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.

Noida, Jan 6: A fire broke out at the ESIC Hospital in Noida on Thursday morning and firefighting was underway, officials said.

The blaze broke out in the basement of the seven-storey hospital building located in Sector 24, a police official said.

Fire tenders were rushed to the spot after the Fire Department was alerted about it around 8 am, the official said.

After that, a search was done to see if anyone was trapped in the building, he said.

The cooling process is now underway.

He said the fire had engulfed the ground, first and second floors of the building, except the basement.

Police said they received information about fire at Kaveri printing press at 2:45 am, when the manager Yogesh called them. The press owners have been identified as Atul and Anuj Goyal, residents of Sukhdev Vihar, they said.

The man who died in the fire has been identified as Phool Dev, from Bihar, who used to work as a help there. Dev went inside the building in the night to sleep before the fire started and died due to suffocation, the fire department official said.

The body has been kept at Lal Bahadur Shastri Hospital and the post-mortem will be done once the family reaches here, police said.
