Mangoes from Andhra Pradesh to line US shelves again
The Union government has secured the approval of the United States Department of Agriculture (USDA) for export of Indian mangoes to the USA in the new season. The export of Indian mangoes has been restricted by the USA since 2020 as USDA inspectors were unable to visit India due to the Covid-19 pandemic.
The USDA’s approval would pave the way for exports from traditional mango production belts such as Andhra Pradesh.
According to industry sources, traders export about 10,000 tonnes of mangoes from Andhra Pradesh to various countries every year. But the official estimates put this figure at about 2,000 tonnes. The difference in the numbers stems from the fact that the traders, after procuring mangoes from the state, export them from international flights and ports in other states like Maharashtra, Telangana, Karnataka, etc.
Discovery of New Strange Metal
Scientists have recently discovered a new group of metals. The newly discovered metal group is called as “New Strange group of metals”. The characteristics of metals like copper or iron are predictable. That is, their melting point, reaction nature, malleability, ductility are known to human. The characteristics of this new group of metals are yet to be deciphered. They still remain a puzzle. Thus, these metals have been classified as strange metals.
The strange metals are also called non – Fermi liquids. They do not follow the traditional rules of metals. Their behavior was first discovered in cuprates, that is, copper oxides. These cuprates are high temperature super conductors.
The strange metals do not conduct electricity as that of metals. In metals, the electrical charge is carried by electrons. In strange metals, the electrical charge is carried by “Cooper pairs”. These cooper pairs take the charge in wave like pattern. Electrons belong to fermion. The cooper pairs act as bosons.
Russia: White Swan Strategic Missile Bomber
The Russian defence forces recently unveiled a new Tupolev Tu-160M. It is a missile bomber. It is also known as “White Swan”.
The White Swan can fly at an altitude of 600 metres. The bomber has been designed to carry nuclear war heads. It is one of the most heaviest supersonic miliary aircraft.
The White Swan has been unveiled while Russia – NATO tensions are at the peak due to Ukraine crisis.
It can carry 34 tonnes of load. The bomber can deliver 24 cruise missiles. It can trace 14,000 km without refuelling.
The machine can be in the sky for more than a day during combat duties.
It is capable of delivering largest payload. They have the longest range. The heavy bombers were superseded by the strategic bombers in the latter half of 20th century.
The Government of India is working on creating a digital stack of agricultural data. That is storing data related to farmers. Apart from farmer details, the digital agristack also holds all information about which seeds to buy, weather updates, what manures and fertilizers to use, insurance, best agricultural practices to maximize the yield.
Agristack has unique number for every farmer in the country. This numbered file will hold personal information of the farmer. This includes his financial data as well. Apart from farmer details, agri stack will also hold information about weather, agricultural commodity prices in the country and abroad, new science and research techniques, agricultural regulation and permissions.
Cryogenic Engine Test for Gaganyaan
Indian Space Research Organisation (ISRO) successfully conducted the qualification test of cryogenic engine for Gaganyaan programme on January 12, 2022.
The test was conducted for 720 seconds at ISRO Propulsion Complex, in Mahendragiri, Tamil Nadu.
Performance of the engine met with the test objectives and parameters of the engine closely matched with predictions during entire duration of the test.
This engine will be tested for four more times, for a cumulative duration of 1810 seconds.
Following this, one more engine will undergo two short-duration tests and one long-duration test, in a bid to complete cryogenic engine qualification for GaganyaanProgramme.
Payload under the Gaganyaan mission consists of:
- Crew module– A spacecraft to carry human beings.
- Service module– It is powered by two liquid propellant engines and will be equipped with emergency mission abort and emergency escape.
- Launch– Gaganyaan would be launched aboard the GSLV Mk III, also dubbed as LVM-3 (Launch Vehicle Mark-3)). It is a three-stage heavy lift launch vehicle.
National E-Governance Conference
The Department of Administrative Reforms and Public Grievances (DARPG), State Government of Telangana, and Ministry of Electronics and Information Technology will host the 24th National E-Government Conference.
