Cops avert murder and communal riot by arresting Bajrang Dal leader, associates

Bengaluru, Apr 10: The Karnataka Education Board on Friday further postponed the annual examination for SSLC to May due to extension of lockdown to arrest spread of coronavirus which is spreading like wildfire in the state.

Minister for Primary and Higher Education S Suresh Kumar also announced that the PUC examination were also postponed to May.

"However, depending upon the situation we will announce the date in May and will inform the students one week earlier of the examination date to give time for preparation,"

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Dammam: President of Indian Social Forum, Eastern Province Mr.Wasim Rabbani urged immediate intervention of Indian government to help Non Residential Indians who are in trouble due to corona pandemic in Saudi Arabia.

He said in a press rease that expatriate Indians are in concern  as number of corona infected people and  deaths are increasing in danger level.

Hea said, "the Saudi health minister's statement a few days ago indicates that the situation in Saudi needs to be taken more seriously with precautionary methods. There are concerns among expatriates because the number of people infected with the coronavirus and the number of deaths reported in various provinces are increasing at an alarming rate."

"Saudi Government and Health Ministry are taking excellent precautionary measures, however, in the coming days expect to see the number of cases to increase in Saudi Arabia. The Indian government needs to take diplomatic and immediate intervention to ensure the treatment of Indian expatriates considering the number of effected people increasing", He said.

He also urged that the Embassy and the Government of India should ensure qaurantiane faculty for Indian expatriates and arrange special low cost flights to bring back expatriates who would like to return home country.

" Government of India and Indian embassy need to intervene immediately to ensure that the quarantine system is in place for Indian expatriates as the facilities in the rooms where the residents are staying together are very limited. There should also be a mechanism to organize low-cost flight services for expatriates who are ready to go home. The government system should also be able to accommodate the expatriates in special quarantine areas in hometown as soon they arrive in India", he urged.
