Shiv Sena asks Modi if Yoga will relieve pain of inflation

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

India ranked 77th on a sustainability index that takes into account per capita carbon emissions and ability of children in a nation to live healthy lives and secures 131st spot on a flourishing ranking that measures the best chance at survival and well-being for children, according to a UN-backed report.

The report was released on Wednesday by a commission of over 40 child and adolescent health experts from around the world. It was commissioned by the World Health Organization (WHO), UN Children's Fund (UNICEF) and The Lancet medical journal.

In the report assessing the capacity of 180 countries to ensure that their youngsters can survive and thrive, India ranks 77th on the Sustainability Index and 131 on the Flourishing Index, it said.

Flourishing is the geometric mean of Surviving and Thriving. For Surviving, the authors selected maternal survival, survival in children younger than 5 years old, suicide, access to maternal and child health services, basic hygiene and sanitation, and lack of extreme poverty.

For Thriving, the domains were educational achievement, growth and nutrition, reproductive freedom, and protection from violence.

Under the Sustainability Index, the authors noted that promoting today's national conditions for children to survive and thrive must not come at the cost of eroding future global conditions for children's ability to flourish.

The Sustainability Index ranks countries on excess carbon emissions compared with the 2030 target. This provides a convenient and available proxy for a country's contribution to sustainability in future.

The report noted that under realistic assumptions about possible trajectories towards sustainable greenhouse gas emissions, models predict that global carbon emissions need to be reduced from 39·7 giga­ tonnes to 22·8 gigatonnes per year by 2030 to maintain even a 66 per cent chance of keeping global warming below 1·5°C.

It said that the world's survival depended on children being able to flourish, but no country is doing enough to give them a sustainable future.

"No country in the world is currently providing the conditions we need to support every child to grow up and have a healthy future," said Anthony Costello, Professor of Global Health and Sustainability at University College London, one of the lead authors of the report.

"Especially, they're under immediate threat from climate change and from commercial marketing, which has grown hugely in the last decade," said Costello – former WHO Director of Mother, Child and Adolescent health.

Norway leads the table for survival, health, education and nutrition rates - followed by South Korea and the Netherlands. Central African Republic, Chad and Somalia come at the bottom.

However, when taking into account per capita CO2 emissions, these top countries trail behind, with Norway 156th, the Republic of Korea 166th and the Netherlands 160th.

Each of the three emits 210 per cent more CO2 per capita than their 2030 target, the data shows, while the US, Australia, and Saudi Arabia are among the 10 worst emitters. The lowest emitters are Burundi, Chad and Somalia.

According to the report, the only countries on track to beat CO2 emission per capita targets by 2030, while also performing fairly – within the top 70 – on child flourishing measures are: Albania, Armenia, Grenada, Jordan, Moldova, Sri Lanka, Tunisia, Uruguay and Vietnam.

"More than 2 billion people live in countries where development is hampered by humanitarian crises, conflicts, and natural disasters, problems increasingly linked with climate change," said Minister Awa Coll-Seck from Senegal, Co-Chair of the commission.

The report also highlights the distinct threat posed to children from harmful marketing.

Evidence suggests that children in some countries see as many as 30,000 advertisements on television alone in a single year, while youth exposure to vaping (e-cigarettes) advertisements increased by more than 250 per cent in the US over two years, reaching more than 24 million young people.

Studies in Australia, Canada, Mexico, New Zealand and the US – among many others – have shown that self-regulation has not hampered commercial ability to advertise to children.

Children's exposure to commercial marketing of junk food and sugary beverages is associated with purchase of unhealthy foods and overweight and obesity, linking predatory marketing to the alarming rise in childhood obesity, it said.

The number of obese children and adolescents increased from 11 million in 1975 to 124 million in 2016 – an 11-fold increase, with dire individual and societal costs, the report said.

To protect children, the authors call for a new global movement driven by and for children.

Specific recommendations include stopping CO2 emissions with the utmost urgency, to ensure children have a future on this planet; placing children and adolescents at the centre of global efforts to achieve sustainable development, the report said.

New policies and investment in all sectors to work towards child health and rights; incorporating children's voices into policy decisions and tightening national regulation of harmful commercial marketing, supported by a new Optional Protocol to the UN Convention on the Rights of the Child, it said.

Bengaluru, Jul 16: Former Prime Minister and JDS supremo H D Devegowda on Thursday gave a clarion call to party workers to take steps to strengthen the party from the grossroots level and to 'expose the failures' and 'anti-people' policies of BJP government both at the Centre and State.

In an open letter to the workers here, he alleged that the urgent need is to create awareness among the people about failure of the governments which have brought in policies which are deterrent to the poor and downtrodden.

BJP government headed by Chief Minister B S Yediyurappa in Karnataka has come up with an amendment to the Land Reforms Act,1961, which is 'against' interests of the small and medium farmers as even a non-agriculturist can purchase agriculture land, thus giving an opportunity to the rich people to 'exploit' illiterate farmers and purchase their land and use it for some other purpose after some time.
