New Delhi, Sept 7: India has successfully flight tested hypersonic technology that will pave the way towards development of missiles travelling at six times the speed of sound.

With this successful demonstration, the country enters an elite club to become a member of the hypersonic regime. This is a step towards manufacture of advanced Hypersonic Vehicles. India became the fourth country after the United States, Russia and China to get this technology.

The Defence Research and Development Organisation (DRDO) successfully demonstrated the Hypersonic air-breathing scramjet technology with the flight test of Hypersonic Technology Demonstration Vehicle (HSTDV) at 11:03 am on Monday from the APJ Abdul Kalam Launch Complex at Wheeler Island, off the coast of Odisha.

Defence Minister Rajnath Singh has appreciated the DRDO for achieving this milestone.

"The Hypersonic cruise vehicle was launched using a proven solid rocket motor, which took it to an altitude of 30 km, where the aerodynamic heat shields were separated at hypersonic Mach number," said the DRDO in a statement.

The cruise vehicle separated from the launch vehicle and the air intake opened as planned. The hypersonic combustion sustained and the cruise vehicle continued on its desired flight path at a velocity of six times the speed of sound.

Critical functions such as fuel injection and auto ignition of scramjet have demonstrated technological maturity. The scramjet engine performed in a textbook manner.

The parameters of launch and cruise vehicle, including scramjet engine, were monitored by multiple tracking radars, electro-optical systems and Telemetry Stations.

The scramjet engine worked at high dynamic pressure and at very high temperature.

A ship was also deployed in the Bay of Bengal to monitor the performance during the cruise phase of hypersonic vehicle.

All the performance parameters have indicated a resounding success of the mission. With this successful demonstration, many critical technologies such as aerodynamic configuration for Hypersonic manoeuvers, use of scramjet propulsion for ignition and sustained combustion at hypersonic flow, thermo-structural characterisation of high temperature materials and separation mechanism at hypersonic velocities can be achieved.

Mangaluru: Dakshina Kannada Zilla Panchayat High School in Harekala, popularly known as Padma Shri awardee Harekala Hajabba’s school, is gearing up to inaugurate its first batch of Pre-University (PU) courses starting June 1. 

The government issued an order to elevate the school established by Padma Shri awardee Harekala Hajabba to the status of a PU College a few months ago.

The School Education and Literacy Department (PU Education) has formally sanctioned the upgrade for the school.

CD Jayanna, the deputy director of PU Education, confirmed that all necessary approvals have been obtained from the government to initiate PU classes.

“Hajabba’s school will kick off PU classes for its inaugural batch on June 1. We have appointed a senior lecturer as the interim principal for the PU college. Presently, the school possesses the essential temporary infrastructure to begin the I PU batch. Plans are underway to enhance the infrastructure for the PU college in the future. Currently, the school boasts adequate classrooms and facilities to commence PU classes,” stated Jayanna.

Harekala Hajabba, an orange vendor, personally erected the school in his native village, New Padpu in Harekala, situated approximately 35 km from Mangaluru. For several years, he has tirelessly petitioned the government for the establishment of a PU college.

Expressing his gratitude, Hajabba mentioned that 19 students who recently completed their SSLC examinations are poised to enroll in the new PU college. He added, “We anticipate enrollment from neighboring villages as well. Both the interim principal and the PU education department have been diligently orchestrating the necessary arrangements to initiate classes.” 

He extended his appreciation to the government, local representatives, and officials for their unwavering support.

AstraZeneca said on Tuesday it had initiated the worldwide withdrawal of its COVID-19 vaccine due to a "surplus of available updated vaccines" since the pandemic.

The company also said it would proceed to withdraw the vaccine Vaxzevria's marketing authorizations within Europe.

"As multiple, variant Covid-19 vaccines have since been developed there is a surplus of available updated vaccines," the company said, adding that this had led to a decline in demand for Vaxzevria, which is no longer being manufactured or supplied.

According to media reports, the Anglo-Swedish drugmaker has previously admitted in court documents that the vaccine causes side-effects such as blood clots and low blood platelet counts.

The firm's application to withdraw the vaccine was made on March 5 and came into effect on May 7, according to the Telegraph, which first reported the development.

London-listed AstraZeneca began moving into respiratory syncytial virus vaccines and obesity drugs through several deals last year after a slowdown in growth as COVID-19 medicine sales declined.

Bengaluru: Karnataka Deputy Chief Minister D K Shivakumar and other state ministers on Saturday rubbished allegations about their role in the circulation of pen drives containing explicit videos involving Hassan MP Prajwal Revanna.

BJP leader and advocate G Devaraje Gowda, who is in custody after being arrested in a sexual abuse case and is also facing charges of video leak, on Friday alleged that Shivakumar and four other ministers are behind the circulation of the pen drives and was being fixed in false cases as he did not agree to be part of their plan.

He has even alleged that he was offered Rs 100 crore by Shivakumar to "bring a bad name" to the BJP and Prime Minister Narendra Modi, and to tarnish the image of JD(S) leader H D Kumaraswamy in Prajwal Revanna's obscene video case.

Speaking to reporters here, Shivakumar said, "Better, let him (Gowda) file a case before Lokayukta or any other agency. I think he has some problems mentally. I'm very sorry, the national and state media shouldn't have picked up such baseless allegations. A person who is in jail, how can he make such allegations? All these are baseless. I don't want to comment." 

Asked if he will be filing any defamation case against Gowda, he said, "I don't want to make any comment or speak on a person who is mentally sick. I appeal to his party people to get him a good treatment." Shivakumar also asserted that his government's commitment to get justice for women victims of the sexual abuse case, and expressed confidence about the Special Investigation Team's (SIT) ongoing probe.

While being taken from court in Hassan, Gowda on Friday spoke to media and alleged that Shivakumar is behind pen drive case, and a team of four Ministers -- N Chaluvarayaswamy, Krishna Byre Gowda, Priyank Kharge and another minister -- was formed to handle this, with an intention to bring bad name to BJP, PM Modi and Kumaraswamy.

He said Shivakumar had asked him to say that Kumaraswamy is behind the distribution of pen drives, but as he did not agree to it, he is being fixed in false cases.

Minister Priyank Kharge said Gowda has alleged that three responsible ministers in the state government were part of a team and that there was a conspiracy. "We will discuss whatever legal course, we will take it." 

"Devaraje Gowda might be doing this to defame Shivakumar and Siddaramaiah. If he had a Rs 100 crore offer, he should have told Amit Shah (Union Home Minister) and get it investigated. He could have got CBI, ED, or IT raids done. Why didn't he do it? Claims have been made that he (Gowda) was sent Rs 5 crore as advance at a club, let them get CCTV footage and see who were all there," Kharge said.

While speaking to reporters here, he further said Gowda is a lawyer. When he was deposed before the Judge he should have told about the documents he has and should have presented to the court.

Minister Chaluvarayaswamy said allegations about the role of Shivakumar and a team of ministers being formed to oversee the circulation of pen drives are 'baseless', and he questioned Gowda's morality to make such accusations.

"If Gowda proves that Chaluvarayaswamy, Priyank Kharge and Krishna Byre Gowda had held a meeting on this case and we as a team were given responsibility and we were involved in this case, I will apologise," he said and alleged that Gowda was being used to mislead and deviate from the main case of sexual abuse.
