 The S-400 system can also additionally include an all-altitude radar (detector) and movable towers for an antenna post, they said. The target detection range of this system is up to 600 kilometres and its tactical ballistic missile destruction range varies from five kilometres to 60 kilometres.Mumbai: Haze envelopes Mumbai as the air quality deteriorated on Saturday after a continuous spell of moderate air quality. The over all air quality index, the indicator of EPTFE sterilization high-efficiency bubble point membrane pollutants in the air soared up to 233, that comes in ‘poor’ category, according to the System of Air quality And weather Forecast And Research (SAFAR).

This is the second consecutive days of hazy air in Mumbai after monsoon this year that the air quality has decreased at such levels where some areas recorded AQI above 300 (very poor).Experts from Indian Meteorological Department (IMD) have attributed the AQI to the spike in both air pollutants and the increased humidity levels. The maximum humidity levels recorded in the last 24 hours since 8.30 am on Friday rose to 95 per cent.”The moisture in the air tends to trap dust particles, which remains suspended for a longer time. The air quality may remain same for next 24 hours after which it will get better,” said an IMD official.

The air quality at Bandra Kurla Complex remained the poorest on Saturday with PM2.5 levels, mostly arising from vehicular emissions, at 330 followed by Andheri (317), Mazagaon (255), Colaba (235), Borivali (225) and Chembur (207). Navi Mumbai too recorded ‘very poor’ levels of pollutants at 331 AQI. The AQI between 200-300 is considered as ‘poor’, while the AQI more than 300 is recorded as ‘very poor’ category.According to Gufran Beig, project director at SAFAR, prolonged exposure to ‘very poor’ air quality could lead to health concerns like coughing or shortness of breath for people sensitive to air pollution and asthmatic patients.

“While we saw this work in Iran, over time countries can adjust to sanctions,” he said.Scientists have created a new material that disintegrates itself at an appointed time, an advance that may pave the way for products like vanishing ink and molecules for drug China Wholesale EPTFE waterproof and breathable composite material delivery. The secret behind self-destructing molecules is that they would require a tiny input of energy to stay in their useful form, without it they disintegrate, researchers said. “A cell constantly needs nutrients and energy. Otherwise, it would just fall apart to its simple building blocks,” said Job Boekhoven, from the Technical University of Munich in Germany.

The molecular structures life forms uses are always “out of equilibrium,” meaning they require a constant influx of energy, such as from food, to keep functioning.Without this energy, the molecules will eventually dissociate on their own and return to a simpler state, Boekhoven said. Applying the same techniques the team created a few different types of materials that require energy input to stay in their current forms, which the scientists call supramolecular molecules. The first material was a simple colloid made of tiny beads, each of which are just one per cent as big as the diameter of a human hair.As fuel is added, the miniature beads assemble like a string of pearls, and they can be tuned to assemble and disassemble in a certain order and at certain times, researchers said.

They envision these materials being used to deliver drugs. For instance, certain drugs need to bypass stomach acid, so if they are timed to disassemble only after they have passed into the gut, they could protect drugs until they reach the desired location. The team also tested a fluffy crystalline material that is normally see-through but becomes cloudy and opaque when a fuel is poured on top of them. As the fuel is used up, dark spots become clear again.The team envisions this material being used as a completely erasable ink, researchers said.”So, you can create a temporary message that erases with a predefined lifetime. A material like that could dramatically reduce the use of ordinary paper in things like bills, tickets and receipts,” said Boekhoven.

 Air Chief Marshal Rakesh Kumar Singh Bhadauria on Friday officially admitted for the first time that an Indian Air Force missile had shot down China EPTFE liquid filtration membrane Suppliers its own Mi-17 helicopter in Kashmir on February 27, calling it a “big mistake”.The incident had resulted in the death of seven people, including six IAF personnel on board the chopper and a civilian on the ground.Earlier media reports that IAF’s air defence missile had shot down Mi-17 helicopter in Budgam in the Kashmir Valley minutes after Pakistan Air Force fighter aircraft had entered Indian air space on February 27 were mostly based on sources.”The helicopter was hit by our own missile. This has been established. This was a mistake, a big mistake. We admit that,” Chief of Air Staff Bhadauria said.The helicopter was hit by the missile when it was approaching the airbase and was in contact with air traffic control (ATC).Air Chief Bhadauria added that the court of inquiry on the incident has just recently been completed.

He said that IAF has taken administrative action against two officers and disciplinary action will also be taken in the future as per process. Air Chief Bhadauria said that those who were killed on the chopper will be treated as battle casualty and awards will be given to the family of those killed.”Necessary steps have been taken that these things are not repeated,” he said.Pakistan Air Force (PAF) had entered the Indian air space near Nowshera to bomb militarily installations in retaliation to airstrikes carried out by IAF at terror camps in Balakot. According to sources, the investigation report said that the “Identification of Friend or Foe” (IFF) system on-board the helicopter was switched off and there was a “vital gap” in communication and co-ordination between the ground staff and the crew of the chopper.

 Despite being in touch with the ATC, the helicopter was hit by missiles as the weapon operators thought it was an unmanned aircraft.The IFF helps air defence radar identify whether an aircraft or helicopter is friendly or hostile. The Mi-17 V-5 chopper had crashed within 10 minutes of taking off, as Pakistan Air Force and IAF aircraft were involved in a dogfight.Speaking about the Mirage 2000 crash in Bengaluru in February, in which two test pilots were killed, the Air Chief said that the court of inquiry is yet to be completed. “It is a priority. We are in full grip of the issue. Something failed and there was an un-commanded movement. We are waiting for some inputs from OEM (Original Equipment Manufacturer),” he added.
