Kalladka clash: HJV leader Ratnakar Shetty, Khaleel externed from DK for 6 months

Bengaluru, Jan 30: The BJP government of Karnataka has given green signal to the proposal of hiking milk prices by Rs 2 per litre.

The new prices will come into effect from February 1. Seeking revision of prices, the Karnataka Milk Federation (KMF) had submitted a proposal last week to the state government. Alongside the revision of milk prices, the state government has also hiked the prices of curd by Rs 2 per liter.

The sudden hike in the prices of milk, curd is likely to have a cascading effect on the milk related beverages such as coffee, tea, and milkshakes with hoteliers and eateries mulling to increase the prices of coffee and tea following the hike in prices.

Sources in the state government revealed to DH that out of Rs 2, farmers will be getting a lion’s share as their accounts will be credited with Rs 1. Another 40 paise will be given to the farmers towards the insurances of their livestock.

Another 40 paise will go to the milk salesmen in the form of commission. The remaining 20 paise will be distributed among the workforce at the milk cooperative unions as an additional incentive.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Mangaluru, Jun 15: A father and his four-year-old son were killed when their motorcycle was hit by a lorry from behind at Bakampady junction on the outskirts of the city.

The Police said the deceased has been identified as Abdul Bhasheer, a resident of Krishnapura and his son Shayan. 

On Sunday evening, Bahseer was going from Mangaluru to Krishnapura by the motorcycle along with wife and son when a speeding lorry "dashed into the motorcycle from behind and knocked them down''.

The four-year-old son died on the spot while Basher and his wife were rushed to the hospital. However, the husband succumbed to injuries at the hospital on Monday. Local police registered a case in this connection.
