‘Due to communication gap’: BSP MLA on his expulsion after not voting in favour of HDK govt

Udupi, Jan 17: Six fishermen were rescued by members of another fishing boat after their boat capsized off Gangolli coast in the District recently.

Police on Friday said that the fishing boat, belonging to Jayalakshmi of Kodi Kanyana, had set sail from Malpe towards Gangolli on the night of January 12. On Wednesday (Jan 15) the vessel’s hull got damaged and water began gushing in.

Bengaluru, Jul 1: The Meteorological Department has issued a yellow alert and forecasted heavy rains for three coastal districts and 12 more in the south interior Karnataka region, an official said on Tuesday afternoon.

"Thunderstorm with lightning is likely to occur at isolated places over south interior Karnataka from Tuesday to Wednesday," said a Met official.

For Bengaluru city, the Met department has forecast a generally cloudy sky with light rain for the next three days.

Coastal Karnataka -- Dakshina Kannada, Udupi and Uttara Kannada districts have been issued a yellow alert for the next two days with thundershowers and gusty winds.

Winds blowing at speed of 40-50 km per hour are expected on the coast and the Met department warned fishermen against venturing into the sea.

Meanwhile, heavy showers on Sunday night in Vijayapura district gave rise to flash floods in the Doni river and Sogali stream.

An overflowing Doni river submerged the Talikote - Hadaginal bridge, a remnant from the colonial era, and also submerged some agricultural lands. Only recently, these agricultural lands were sown with toor dal plants.

Similarly, many SSLC students also struggled to cross the bridge to reach their examination centres on Monday.

Many houses were also flooded due to the rainfall at Nalatwad and Talikote taluk. Muddebihal, Basavana Bagewadi and Sindagi taluks also witnessed heavy rainfall.

A 40-year-old farmer from Dharwad district was washed away in the Tuppari Halla stream, which is prone to flood during the monsoon season.

Likewise, a truck carrying cotton also got washed away in a stream in Yadgir district.

"There is an offshore trough and a circulation, because of which rain will continue in the coastal area. Only Malnad has not got sufficient rain this year. Probably after two days, Malnad may get some rains," Karnataka State Natural Disaster Monitoring Centre (KSNDMC) Director Srinivas Reddy said. Otherwise, entire state got normal rainfall, said Reddy, though it is not active over Malnad.

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
