Like Bajrang Dal, many Muslims have sacrificed lives for cow protection: RSS chief

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.

New Delhi, Feb 16: Aam Aadmi Party (AAP) national convener Arvind Kejriwal was on Sunday sworn-in as the Chief Minister of Delhi for the third time in a row at Ramlila Maidan here, after his party registered a massive victory in the recently concluded Delhi Assembly polls.

Kejriwal was administered the oath of office and secrecy by Delhi Lieutenant Governor Anil Baijal.

The sprawling Ramlila Maidan reverberated with sounds of thousands of people cheering for the AAP leader.

Kejriwal who received a hero's welcome here had extended an invitation to the people of Delhi urging them to attend the swearing-in ceremony to witness "the son of Delhi" taking oath today.

The AAP nearly repeated its 2015 performance in the elections, sweeping the Assembly polls winning 62 seats in the 70-member Assembly, in the face of a high-voltage campaign by the BJP, which fielded a battery of Union Ministers and Chief Ministers in its electioneering spearheaded by Home Minister Amit Shah. 

London, May 20: The current physical distancing guidelines of 6 feet may be insufficient to prevent COVID-19 transmission, according to a study which says a mild cough in low wind speeds can propel saliva droplets by as much as 18 feet.

Researchers, including those from the University of Nicosia in Cyprus, said a good baseline for studying the airborne transmission of viruses, like the one behind the COVID-19 pandemic, is a deeper understanding of how particles travel through the air when people cough.

In the study, published in the journal Physics of Fluids, they said even with a slight breeze of about four kilometres per hour (kph), saliva travels 18 feet in 5 seconds.

"The droplet cloud will affect both adults and children of different heights," said study co-author Dimitris Drikakis from the University of Nicosia.

According to the scientists, shorter adults and children could be at higher risk if they are located within the trajectory of the saliva droplets.

They said saliva is a complex fluid, which travels suspended in a bulk of surrounding air released by a cough, adding that many factors affect how saliva droplets travel in the air.

These factors, the study noted, include the size and number of droplets, how they interact with one another and the surrounding air as they disperse and evaporate, how heat and mass are transferred, and the humidity and temperature of the surrounding air.

In the study, the scientists created a computer simulation to examine the state of every saliva droplet moving through the air in front of a coughing person.

The model considered the effects of humidity, dispersion force, interactions of molecules of saliva and air, and how the droplets change from liquid to vapour and evaporate, along with a grid representing the space in front of a coughing person.

Each grid, the scientists said, holds information about variables like pressure, fluid velocity, temperature, droplet mass, and droplet position.

The study analysed the fates of nearly 1,008 simulated saliva droplets, and solved as many as 3.7 million equations.

"The purpose of the mathematical modelling and simulation is to take into account all the real coupling or interaction mechanisms that may take place between the main bulk fluid flow and the saliva droplets, and between the saliva droplets themselves," explained Talib Dbouk, another co-author of the study.

However, the researchers added that further studies are needed to determine the effect of ground surface temperature on the behaviour of saliva in air.

They also believe that indoor environments, especially ones with air conditioning, may significantly affect the particle movement through air.

This work is important since it concerns safety distance guidelines, and advances the understanding of the transmission of airborne diseases, Drikakis said.
