 ANSWER: C

 ANSWER: B

 ANSWER: C

 ANSWER: C

• The world’s first conservation and breeding center for the Asian king vulture is set to open in Uttar Pradesh’s Maharajganj district.
• The center, named Jatayu Conservation and Breeding Centre (JCBC), is spread over 1.5 hectares and is designed to maintain a sustainable population of the species by breeding king vultures in captivity and releasing them into the wild.
• The JCBC, worth approximately Rs 15 crore, features multiple aviaries, including breeding and holding aviaries, nursery aviaries for juveniles, hospital and recovery aviaries, a food processing center, and an incubation center.
• The forest department has partnered with the Bombay Natural History Society for technical guidance.

About Asian King vulture

• It is also called the Red headed vulture or Pondicherry Vulture and was extensively found in India but its numbers drastically reduced after diclofenac poisoning.
• IUCN Status: Critically Endangered
• Wildlife Protection Act, 1972: Schedule 1

 ANSWER: A

• Physicists in Japan discovered a previously unknown isotope of uranium, with atomic number 92 and mass number 241, i.e Uranium-241 and its half-life, according to theoretical calculations, could be 40 minutes.

About Uranium

• Uranium is a naturally occurring chemical element with the symbol U and atomic number 92.
• It is a silvery-grey metal in the actinide series of the periodic table.
• Uranium has several isotopes, which are atoms that have the same number of protons but different numbers of neutrons like U-235 and U-238.
• It is a heavy metal that is radioactive and found in small quantities in rocks and soils worldwide.

Static Information

• Atomic number = No. of Protons = No. of Electrons
• of Neutrons = Atomic mass– Atomic No.

Uranium-241 discovery

• The researchers accelerated uranium-238 nuclei into plutonium-198 nuclei at the KEK Isotope Separation System (KISS).
• In a process called multinucleon transfer, the two isotopes exchanged protons and neutrons.
• The resulting nuclear fragments contained different isotopes.
• This is how the researchers identified uranium-241 and measured the mass of its nucleus by using time-of-flight mass spectrometry.

Magic numbers

• In nuclear physics, a magic number is a number of nucleons (either protons or neutrons, separately) such that they are arranged into complete shells within the atomic nucleus.
• As a result, atomic nuclei with a ‘magic’ number of protons or neutrons are much more stable than other nuclei.
• The heaviest known ‘magic’ nucleus is lead (82 protons).

 ANSWER: B

• The country’s first 3D-printed post office is coming up in Bengaluru.
• It is being implemented by Larsen & Toubro
• It is a 1,100 sqft building which is expected to cost 30-40 per cent less than conventional buildings because of the technological intervention.
• It is being built at a cost of Rs 23 lakh.

About 3D-printing

• 3D printing or additive manufacturing is a process of making three-dimensional solid objects from a digital file.
• In an additive process, an object is created by laying down successive layers of material until the object is created.
• Each of these layers can be seen as a thinly sliced cross-section of the object.

 ANSWER: C

• To tackle climate change and pollution, the Brihanmumbai Municipal Corporation ( BMC) recently started creating a Miyawaki forest at Deonar village in Govandi.
• Miyawaki method is named after Japanese botanist Akira Miyawaki.
• The technique involves planting two to four types of indigenous trees within every square meter.
• Miyawaki forests grow 10x faster, are 30 x denser and contain 100x more biodiversity.
• These trees become self-sustainable and grow to their full length within three years.
• It helps lower temperatures in concrete heat islands, reduce air and noise pollution, attract local birds and insects, and create carbon sinks.

 ANSWER: D

• Dakar Declaration has been adopted in principle by 21 African countries after the first African sub-regional conference on implementing Global Plan for Road Safety.
• It is a guiding document to support the implementation of Decade of Action for road safety 2021–2030.
• It sets the ambitious target of preventing at least 50% of road traffic deaths and injuries by 2030.
• It includes actions to enhance data capture, analysis, sharing and coordination to shape better road safety policies.

Other info

• Dakar is the largest city and capital of Senegal.

 ANSWER: A

• The Andaman and Nicobar Command (ANC) recently concluded a two-month-long joint military exercise named ‘Ex KAVACH.’
• The exercise involved the assets of the Army, Navy, Air Force, and Coast Guard and aimed at fine-tuning joint warfare capabilities and enhancing interoperability and operational synergy between the forces.
• It involved amphibious landing, air-landed operations, heliborne operations, and rapid insertion of the Special Forces on a remote Island of the Andaman and Nicobar Islands.

 ANSWER: A

• NASA’s James Webb telescope reveals never before seen details in Cassiopeia A.
• Cassiopeia A is a remnant of a massive star that exploded about 340 years ago
• It is situated in constellation Cassiopeia.
• It is located nearly 11000 light years away from earth.
• It is one of the strongest sources of radio emission in sky beyond solar system.
• Cassiopeia Constellation ranks as 25th largest Constellation. Constellation resembles an irregularly shaped letter “W”

 ANSWER: C

• The state government is launching the Mukhyamantri Vidyarthi Protsahan Yojana from the current financial year to provide educational loans at one per cent interest rate to underprivileged students to help them pursue higher studies and professional courses.
• The scheme covers a wide range of professional courses such as engineering, medical, management, Ph.D, courses in ITIs, polytechnics, B. Pharma, Nursing, General Nursing and Midwifery (GNM).
• The government has proposed Rs 200 crore for the scheme under which students having family income less than Rs 3 lakh per annum can avail loans from partner financial institutions and banks
