Our prophet and our duty...

New Delhi, Jan 26: Google on Sunday marked India's 71st Republic Day by dedicating a doodle illustrating the country's rich cultural heritage that permeates and unites the diverse nation.

From its world-famous landmarks like the Taj Mahal and India Gate, to the wide array of fauna such as its national bird (the Indian peafowl), to classical arts, textiles, and dances, the doodle, designed by Singapore-based artist Meroo Seth, brings together the rich cultural heritage of the country.

Republic Day marks the completion of India's transition towards becoming an independent republic after its constitution came into effect. The governing document had taken nearly three years of careful deliberation to finalise, and its eventual enactment was joyfully celebrated across the country.

While the Constitution was adopted by the Indian Constituent Assembly on 26 November 1949, it came into effect on January 26 -- a day when Declaration of Indian Independence (Purna Swaraj) was proclaimed by the Indian National Congress back in 1929, as opposed to the Dominion status offered by the British Regime.

Festivities embody the essence of diversity found in one of the world's most populous nations, celebrated over a three-day period with cultural events displaying national pride.

Last year's doodle on Republic Day, designed by artist Reshidev RK, had featured Rashtrapati Bhavan in the background along with a display of the country's iconic monuments and heritage.

Beijing, Jun 18:  Besides washing hands and wearing masks, it is also important to close the toilet lid before flushing to contain the spread of COVID-19, as per a new study.

According to a new study cited by The Washington Post, scientists who simulated toilet water and airflows, have found that flushing a toilet can generate a plume of virus-containing aerosol particles that is widespread and can linger in the air long enough to be inhaled by others. The novel coronavirus has been found in the faeces of COVID-19 patients, but it remains unknown whether such clouds could contain enough virus to infect a person.

"Flushing will lift the virus up from the toilet bowl," co-author Ji-Xiang Wang, who researches fluids at Yangzhou University in Yangzhou, China, said in an email. Wang stressed that bathroom users "need to close the lid first and then trigger the flushing process" and wash hands properly if the closure is not possible. As one flushes the toilet with the lids open, bits of faecal matter swish around so violently that they can be propelled into the air, become aerosolised and then settle on the surroundings.

Experts call it the "toilet plume".Age-old studies have been made to understand the potential for airborne transmission of infectious disease via sewage, and the toilet plume's role. Scientists who have seeded toilet bowls with bacteria and viruses have found contamination of seats, flush handles, bathroom floors and nearby surfaces. This is one reason we are told to wash our hands after visiting the toilet. Public bathrooms are well known to contribute to the spread of viruses that transmit via ingestion, such as the noroviruses that haunt cruise ships. However, their role in the transmission of respiratory viruses has not been established, said Charles P Gerba, a microbiologist at the University of Arizona."The risk is not zero, but how great a risk it is, we do not know. The big unknown is how much virus is infectious in the toilet when you flush it ... and how much virus does it take to cause an infection," said Gerba, who has studied the intersection of toilets and infectious disease for 45 years.

A study published in March in the journal Gastroenterology found significant amounts of coronavirus in the stool of patients and determined that viral RNA lasted in faeces even after the virus cleared from the patients` respiratory tracts. While another study in the journal Lancet found coronavirus in faeces up to a month after the illness had passed.

Scientists around the world are now studying sewage to track the spread of the virus. According to the researchers, the presence of the virus in excrement and the gastrointestinal tract raises the prospect of transmission via toilets, because many COVID-19 patients experience diarrhoea or vomiting.

A study of air samples in two hospitals in Wuhan, China found that although coronavirus aerosols in isolation wards and ventilated patient rooms were very low, "it was higher in the toilet areas used by the patients".The Centers for Disease Control and Prevention (CDC) says it remains "unclear whether the virus found in faeces may be capable of causing COVID-19," and "there has not been any confirmed report of the virus spreading from faeces to a person".For now, the CDC characterises the risk as low based on observations from previous outbreaks of other coronaviruses such as severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome (MERS). Wang decided to use computer models to simulate toilet plumes while isolating at home, as per Chinese government orders and thinking about how a fluids researcher "could contribute to the global fight against the virus".

Published in the journal Physics of Fluids, the study found that flushing of both single-inlet toilets, which push water into the bowl from one port, and annular-inlet toilets, which pour water into the bowl from the rim's surrounding edge with even greater energy, results in "massive upward transport of virus".

Particles can reach heights of more than three feet and float in the air for more than a minute, it found. The paper recommends not just lid-closing and hand-washing, it urges manufacturers to produce toilets that close and self-clean automatically. It also suggests that toilet-users should wipe down the seat. Gerba, however, said seats should not be a major concern.

Research has found that public and household toilet seats are typically the cleanest surfaces in restrooms, he said, probably because so many people already wipe them off before using them. Also, he said of SARS-CoV-2, the virus that causes COVID-19, "I don't think it's butt-borne, so I don`t think you have to worry."Gerba, who has been studying coronavirus transmission for two decades to investigate the role of a toilet flushing in a SARS outbreak stresses "flush and run" when using a public toilet without a lid. Gerba also said that people should wash hands well post-flushing and use hand sanitiser after leaving the restroom. "Choose well-ventilated bathrooms if possible and do not hang around the restroom in any case," added Gerba.

Mumbai, Jan 27: The country's largest car maker Maruti Suzuki India (MSI) on Monday said it has increased prices of select models by up to Rs 10,000 with immediate effect to offset the impact of rising input costs.

The price change varies across models and ranges up to 4.7 per cent (ex-showroom Delhi) and are effective from January, 27 2020, MSI said in a statement.

The price of entry level model Alto range has gone up in the range of Rs 9,000-6,000, S-Presso between Rs 1,500 to 8,000, WagonR between Rs 1,500 and Rs 4,000.

The company has also increased the price of its multi purpose vehicle Ertiga between Rs 4,000-10,000, Baleno by Rs 3,000 to 8,000 and XL6 by up to Rs 5,000 (all prices ex-showroom Delhi).

Currently, the company sells a range of vehicles starting from entry-level small car Alto to premium multi purpose vehicle XL6 with price ranging from Rs 2.89 lakh to Rs 11.47 lakh (ex-showroom Delhi).
