Cong playing caste politics in Karnataka; BJP’s only agenda is development: PM Modi

Mangaluru, Jul 16: Streets in Mangaluru wore a deserted look as the city woke up to the first morning of the seven-day lockdown on Thursday.

The lockdown is being observed after the state government announced it as a necessary step to combat the spread of COVID-19.

The week-long total shutdown came into effect in the Karnataka's Dakshina Kannada district from 8 pm on July 15 till 5 am on July 22.

The state government allowed relaxation between 8am to 11 am for purchasing of essential commodities. A slight rush was observed during the hours of the relaxation.

Karnataka has so far reported 47,253 positive COVID-19 cases, including 27,859 active cases and 18,466 recoveries.

So far, 928 people have lost their lives due to the infectious virus in the state.

Bengaluru, Jun 18: Real estate continues to be a preferred asset class for investors amid the uncertainty emerging out of the pandemic, according to a report by National Real Estate Development Council (NAREDCO) and Housing.com.

Titled 'Concerned yet positive - The Indian Real Estate Consumer (April-May 2020)', the report showed that the real estate consumer remains positive with regard to the economic scenario and income stability for the coming six months.

"Real estate (35 per cent) is still perceived as the preferred mode of investment, followed by gold (28 per cent), fixed deposits (22 per cent), stocks (16 per cent) and homebuyers are likely to slowly return to the market in the coming six months," it said.

Price-points of residential realty have remained muted for the past few years, but are still a key deterrent, with the perception of being still unaffordable, according to nearly half of the potential homebuyers surveyed, who are currently staying in rented accommodation.

A majority of respondents surveyed (73%) comprise 'first time homebuyers', who are looking to buy a 'ready-to-move-in-house' for end-use and are from the age group of 25-45 years. While 60% of respondents opined that for the next six months, they would prefer a ready-to-move-in property, 21% said they were okay with a property with a delivery timeline of maximum one year.

The survey was conducted in April and May 2020, through a random sampling technique for a fair representation across regions. The insights presented in the survey represent the view of more than 3,000 potential homebuyers.

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
