I-T unearths Rs 871 crore scam in Rajkot bank

Mangaluru, Apr 23: An astronomical phenomenon, ‘Zero Shadow Day', will be observed in Mangaluru on April 24 and in Udupi on April 25. 

According to a press release from Poornaprajna Amateur Astronomers’ Club, the wonder will commence and people will see their shadows disappear for a few moments at 12:28 pm.

The phenomenon is called as Zero Shadow Day. If a person takes a candle in a dark room and use it to create a shadow of one’s palm on the wall, the hand will cast shadow on the wall as one moves the hand. But when one places the palm on the wall, there will be no shadow.

In the phenomenon, the sun at these times shines exactly above the heads on these days. In astronomy, this point is called as Zenith. The point in the sky directly above an observer at any given location. So it is quite clear now that on Zero Shadow Day, the sun passes through the Zenith as a result of which, all objects will have minimal or no shadow if they are on the ground.

The reason for this happens on some specific days is concerned with astronomy. The earth spins around on its own axis and causes days and nights. It also revolves around the sun causing a year. But the seasons are caused because the axis is tilted at an angle of 23.5 degrees. It is because of this tilt that the sun rises every day in the east gradually moving towards the north till June 21st and then slowly proceeding towards the south till December 21st every year. “We call these days solstice. This means the sun shines between the Tropic of Cancer and Tropic of Capricorn every day passing by the equator on the days we call equinox,” the release stated.

As the earth moves around the sun and revolves on its own axis, for all the people between Tropic of Cancer and Tropic of Capricorn, the Sun at noon moves father and closer to the zenith passing through zenith twice causing two Zero Shadow Days per year. People at Mangaluru will observe this on April 24 and August 18 every year and People in Udupi will observe this on April 25 and August 17 every year.

Places with same latitudes will observe the same days of Zero Shadow but the time would vary with longitude. For example, people of Bengaluru as they share the latitude with Mangaluru will also observe it on April 24. While the people of Mangaluru will observe their shadows disappear at 12.28pm, people of Bengaluru will observe this at 12:17pm. Places like Moodabidri, Bantwal, Sakleshpur and Hassan will also observe Zero Shadow on April 24.

Places like Brahmavar, Karkala, Sringeri, Kudremukha, Chikkamagaluru will observe the Zero Shadow Day on the same day as Udupi on April 25.

New Delhi, Jan 26: On the occasion of the 71st Republic Day, Karnataka state's tableau depicted the philosophy of Basaveshwara and the concept of Anubhava Mantapa (Centre for Experience), which was the socio-religious centre that existed in the present-day Basava Kalyana of Bidar district in Karnataka.

It is regarded as the first religious parliament in the history of mankind.

This 12th-century centre has a special significance in the history of humanity, as it represents composite culture, philosophy, spirituality, equality among other universal human values.

These values were propagated by the saint and social reformer- Basaveshwara and other sharanas- followers of Basava philosophy of the socio-religious movement.

It is significant that representatives of Anubhava Mantapa were nominated based on their spiritual attainment, regardless of caste, class and sect they belonged and thus discarded the differentiation of human beings as higher or lower, on the basis of birth, occupation and gender.

The front part of the tableau has the replica of Basaveshwara preaching his most cherished value - "Work is Worship".

For Republic Day Parade 2020, a total of 56 tableaux proposals (32 from states/UTs and 24 from Ministries/Departments) were received. Out of these, 22 were shortlisted for participation in the Republic Day Parade 2020.

Bengaluru, May 29: A cost-effective state of the art glove box testing booth for swab collection was inaugurated by Karnataka Medical Education Minister Dr K Sudhakar at Victoria hospital.

Inaugurating the specially designed booth for safer, easier and quicker testing, Medical Education Minister Dr Sudhakar said that the portable booths can be used at border check posts and hot spots.

"The testing method involves the collection of samples from inside a box of aluminium and glass. The suspected corona virus-infected individual, whose samples are being taken, has to walk up to the booth and stand in front of the glass exterior. The healthcare worker inside the kiosk collects the sample and then, follows the sanitisation process before proceeding to take the next sample. The collection process, fully contactless, gets over in five minutes," the Minister said.

Dr Sudhakar also said: "This booth significantly reduces manpower requirement and the need for PPE kits. The main advantages of this procedure are that it needs fewer healthcare workers and strictly adheres to the norms of social distancing. 

The booth is low-cost. Each model costs about Rs 15,000-20,000."
It is also portable and can be mounted on a vehicle and transported to any location.

It can be particularly useful for collecting samples in hot spots and border checkpoints, he added.
