New Mangalore Port rescues Filipino crew of Iran-bound ship

Mangalore, Jan 12: Thieves reportedly stole around 70,000 cash from a MESCOM ATP machine located at Chembugudde in Thokkottu, Police said here on Sunday.

Police said that the theft took place in the MESCOM sub-division office at Chembugudde. It was said that the thieves broke open the room where the MESCOM customers bill payment machine was located and stole 70,000 rupees cash from the ATP machine.

This machine had nine lakh rupees cash. The amount was reported to have been transferred at around 1500 hrs on Saturday.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jun 23: Karnataka Medical Education Minister K Sudhakar's wife and daughter have tested positive for COVID-19, a day after his father was confirmed to have been infected with the virus.

"Test results of our family members have come. Unfortunately, my wife and daughter have tested positive for #Covid19 and are undergoing treatment," the minister tweeted on Tuesday.

He said he and his two sons have tested negative.

Sudhakar's father P N Keshava Reddy tested positive for coronavirus on Monday. He was admitted to the hospital with a cough and fever.

Earlier, the domestic help of the minister had tested coronavirus positive and was admitted to a hospital.

In April, Sudhakar was quarantined along with three other ministers for coming in contact with a journalist who was coronavirus positive.

Karnataka reported 249 new COVID-19 cases and five deaths on Monday taking the total number of cases in the state to 9,399 and the death toll to 142.

Test results of our family members have come. Unfortunately, my wife and daughter have tested positive for #Covid19 and are undergoing treatment. My two sons and myself have tested negative. I am grateful to everyone for their best wishes and prayers.
