BJP IT cell chief tweets Karnataka poll dates before EC announcement, sparks row

The current physical distancing guidelines provided by the World Health Organisation (WHO) and by the US Centers for Disease Control and Prevention (CDC) may not be adequate to curb the coronavirus spread, according to a research which says the gas cloud from a cough or sneeze may help virus particles travel up to 8 metres. The research, published in the Journal of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.

Study author, MIT associate professor Lydia Bourouiba, warned that droplets of all sizes can travel 23 to 27 feet, or 7-8 metres, carrying the pathogen.

According to Bourouiba, the current guidelines are based on "arbitrary" assumptions of droplet size, "overly simplified", and "may limit the effectiveness of the proposed interventions" against the deadly pandemic.

 She explained that the old guidelines assume droplets to be one of two categories, small or large, taking short-range semi-ballistic trajectories when a person exhales, coughs, or sneezes.

However based on more recent discoveries, the MIT scientist said, sneezes and coughs are made of a puff cloud that carries ambient air, transporting within it clusters of droplets of a wide range of sizes.

Bourouiba warned that this puff cloud, with ambient air entrapped in it, can offer the droplets moisture and warmth that can prevent it from evaporation in the outer environment.

"The locally moist and warm atmosphere within the turbulent gas cloud allows the contained droplets to evade evaporation for much longer than occurs with isolated droplets," she said.

"Under these conditions, the lifetime of a droplet could be considerably extended by a factor of up to 1000, from a fraction of a second to minutes," the researcher explained in the study.

The MIT scientist, who has researched the dynamics of coughs and sneezes for years, added that these droplets settle along the trajectory of a cough or sneeze contaminating surfaces, with their residues staying suspended in the air for hours.

"Even when maximum containment policies were enforced, the rapid international spread of COVID-19 suggests that using arbitrary droplet size cutoffs may not accurately reflect what actually occurs with respiratory emissions, possibly contributing to the ineffectiveness of some procedures used to limit the spread of respiratory disease," Bourouiba wrote in the study

Bengaluru, Mar 8: Lieutenant General Milind Hemant Thakur, Director-General of Supply and Transport Corps of the Indian Army, unveiled the renovated Animal Memorial at Agram Grounds in ASC Centre and College here on Saturday.

The animal memorial signifies the contributions of mules and horses of the Indian Army. These animals belonging to the Army Service Corps, who have rendered their services relentlessly during the war in the Himalayas, often paying the highest price of sacrificing their lives in the line of duty have been chronicled in the Memorial.

To ensure that these hoof prints do not get obliterated, on approval by the Government of India, their saga was brought to life in the form of a sculptured monument in the Equestrian Training Area of the ASC Centre and College.

This animal transport memorial has now been extended by constructing two walls supported by Roman pillars on either side.

These walls highlight the role played by the animals in the Indian Army since the British Raj. It gives details of 637 gallantry awards won by the brave muleteers, 49 battle casualties since independence, 14 gallantry awards to mules since independence and 05 military recognitions bestowed by the Chief of the Army Staff and other Army Commanders on AT units, who have been relied upon heavily to fill an important niche in the logistics networks of the Indian Army.

Gen Thakur also declared that 26 September each year has been nominated as the AT Remembrance Day as it was on this day in 1914, that 9th mule Corps, as part of the Indian Expeditionary Force, landed at Marseilles in France, to a most hearty and enthusiastic welcome by the French to support the British and allied armies in World War One.

Dubai, May 9: A flight scheduled to bring back Kannadigas, especially Mangalureans stranded in Dubai on May 14 has been rescheduled to May 12.

The flight will take off from Dubai at 4.10 pm UAE time and reach Mangaluru International Airport at 9.10 pm IST on May 12, announced Union Minister DV Sadananda Gowda in a tweet.

The flight was earlier scheduled for May 12 and then it was postponed to May 14. Now, it has been rescheduled to May 12.

It is said that constant persuasion from NRIs in UAE led to advance the paid evacuation drive.

In fact, Karnataka was missing in the list of states to receive special flights when Ministry of External Affairs arranged them to bring stranded Indians at UAE. Special flights were arranged only to Kerala and Tamil Nadu people stranded at UAE in the first stage.

Thanks to Karnataka NRI Forum of UAE which opened helpline to seek assistance to Kannadigas, nearly 2000 Kannadigas have registered for assistance in which 127 pregnant women, 27 senior citizens, 700 people who have lost jobs aftermath of coronavirus sought assistance from NRI forum.

In the first flight, priority will be given to people with medical emergency and pregnant women. Once the passengers reach Mangaluru, they will be quarantined in their home districts.
