Newsroom24x7 Staff

New Delhi: President of India Ram Nath Kovind today said that India will complete 75 years of Independence in the year 2022 and it is our national resolve to attain certain desired milestones for a New India by then.

The President also reminded the nation about the illustrious leaders and the diverse generation that brought freedom to the country. They were men and women who represented all parts of the country and a variety of political and social thought.

The President was addressing the Nation on the eve of India’s 71st Independence Day. From the earliest days of our freedom struggle, we were blessed with a galaxy of revolutionary leaders who guided our country, he said underscoring Mahatma Gandhi’s emphasis on the moral character of India and of the Indian society. Gandhiji spoke of not just political freedom but also principles that are relevant even today.

They spoke of not just political freedom. Mahatma Gandhi emphasised the moral character of India and of Indian society. The principles that Gandhiji spoke about are relevant even today.

The President said:

“Gandhiji was not alone in this nationwide struggle for freedom and reform. Netaji Subhas Chandra Bose exhorted our people, saying: “Give me blood and I will give you freedom”. At his word, millions of Indians joined the freedom movement under his leadership and gave their all.

Nehruji emphasised that India’s age-old heritage and traditions – so dear to us – could co-exist with technology and a quest to modernise our society.

Sardar Patel instilled in us the importance of national unity and integrity. And of a disciplined national character.

Babasaheb Bhim Rao Ambedkar urged upon us the virtues of constitutional governance, of the rule of law – and of the vital need for education.

The government is implementing GST to eliminate multiple taxes and simplify transactions – but it is for each of us to make this an essential part of our everyday transactions and business culture. I am happy that the transition to the GST system has been smooth.

Demonetisation has boosted our efforts to build an honest society. We must sustain this spirit and this momentum.”

Seven defining S&T contributions that have impacted every Indian

Leave a comment

Dinesh C Sharma

New Delhi: As India completes 70 years of its independence, it is time to introspect at the contribution of science and technology to national development. Several scientific and technological developments have touched the lives of common people in the last seven decades, though limelight is often hogged by achievements in fields like space and atomic energy.

In the past seven decades, India has built satellites and sent probes to the moon and Mars, established nuclear power stations, acquired nuclear weapon capability and demonstrated firepower in the form of a range of missiles. Undoubtedly these are all fabulous achievements of Indian scientists and technologists.

At the same time, scientific research – combined with favourable public policies – has made India self-sufficient in production of food, milk, fruits and vegetables, drugs and vaccines. All this has had great social and economic impacts and directly and indirectly touched the lives of ordinary Indians. Developments in communications and information technology have enabled timely forecast of weather and early warning of cyclones, saving thousands of lives.

These are all results of investments made in scientific research soon after the independence and science-politics network built in decades prior to that. Investment in scientific research was 0.1 percent of GNP in 1947. It went up to 0.5 percent in less than a decade. Scientists like Shanti Swarup Bhatnagar, Homi Jehangir Bhabha and Prasanta Chandra Mahalanobis not only built scientific institutions but also helped shape policies.

Here are seven defining contributions of Indian science and technology since 1947:

Green Revolution: In 1947, India produced about 6 million tonnes of wheat which was grossly inadequate to meet the total demand forcing the country to depend on large scale imports. With measures such as land reforms, improvements in irrigation facilities, fertilizer production and Intensive Agriculture District Programme, wheat production rose to 12 million in 1964 – which was still insufficient to feed all Indians. While all this was going on, plant breeder Benjamin Peary Pal at the Indian Agriculture Research Institute was working on improving wheat varieties to achieve disease resistance and yield. The first breakthrough came in 1961 when a dwarf spring wheat variety with the Norin-10 dwarfing gene – developed by Normal Borlaug in Mexico- was grown in IARI. It had reduced height but long panicles. Later semi-dwarf varieties were grown in farmers’ fields, yielding great results. These developments led to launch of the Hugh Yielding Varieties Programme covering not just wheat but rice, maize, sorghum and pearl millet. The All India Coordinated Wheat Research Project under Pal remains an outstanding example of agriculture research. By 1970, wheat production went up to 20 million tonnes and rice production to 42 million tonnes. Thus began the Green Revolution, making India self-sufficient in foodgrain production in the decades to come.

White Revolution: At the time of the independence, India was not only importing foodgrains but also milk products like baby food, butter and cheese. In 1955, India was importing 500 tonnes of butter and 3000 tonnes of baby food from dairy companies in Europe. The dairy movement had started in 1946 with the founding of the Kaira District Cooperative Milk Producers Union Limited under the leadership of Tribhuvandas Patel. In 1949, Verghese Kurien arrived in Anand to fulfil the condition laid down in the bond he had signed with the government at the time of going to America for higher education with government scholarship. He stayed back and became General Manager of the cooperative in 1950. The dairy faced a problem of fluctuating milk production as surplus milk would find no takers. European dairy companies were not willing to part with milk powder technology and were of the view that buffalo milk can’t be converted into milk powder. H M Dalaya, a young diary engineer working with Kurien at Anand, demonstrated with experiments that buffalo milk can be converted into milk powder. Dalaya assembled a device using a spray paint gun and an air heater to make powder from buffalo milk, for the first time in the world. Later he showed that a commercially available machine, Niro Atomizer, could do the same. This laid the foundation for a dairy revolution in India and a national milk grid, making the country self-sufficient.

Satellite and communication revolution: When Vikram Sarabhai, as chairman of the Indian National Committee for Space Research, in mid-1960s envisioned the use of satellite technology for communication, remote sensing and weather prediction, few people believed him because India then did not possess any capability in building a rocket or a satellite. He wanted India to use space technology for education, health and rural development. Within a decade, India not only developed such a capability but demonstrated to the world peaceful use of space technology with the success of the Satellite Instructional Television Experiment (SITE), and the launch of Aryabhata satellite from the Soviet Union. In another decade, Indian scientists launched the landmark INSAT and IRS series of satellites, bringing communication and television services to millions of people across the country. Timely prediction of weather events like cyclones using India-made satellites has helped save lives. Through pioneering use of the VSAT (Very Small Aperture Terminal) technology, banking and other services were revolutionized in the 1980s.

Drugs and vaccines manufacturing: India today is known as ‘pharmacy of the world’ as Indian companies are supplying affordable drugs and vaccines to not only developing but also to developed countries. It has been a long journey from the time when Indian drug industry was dominated by foreign companies whose drugs were prohibitively costly. In order to break the hold of multinational corporations, the central government established Hindustan Antibiotics Limited in 1954 and then the Indian Drugs and Pharmaceuticals Limited (IDPL) with Soviet assistance. These public sector units – along with national laboratories like National Chemicals Laboratory (NCL), Regional Research Laboratory Hyderabad (now known as Indian Institute of Chemical Technology) and Central Drug Research Institute – played a central role in generating necessary knowledge base and human resources needed for Indian industry to grow. The Patent Act of 1970 recognised only process patents, paving the way for Indian companies to make copies of patented drugs using alternative processes. CSIR labs developed processes for a range of drugs – ciprofloxacin, diclofenac, salbutamol, omeprazole, azithromycin etc. – and transferred the technology to private companies. Over next two decades, all this helped develop indigenous capabilities in both R&D and manufacturing.

C-DOT and telecom revolution: Like most other sectors, telecom sector too was dependent on supplies from multinational corporations, and due to high costs as well as shortage of foreign exchange new technology could not come in. The switching technology was considered strategic and only a handful of companies possessed it. The waiting period for a telephone line in India in the 1970s was several years, and connectivity in rural areas was extremely poor. The first attempt to develop an indigenous electronic exchange was initiated at the Telecom Research Centre (TRC) in the 1960s and the first breakthrough was a 100-line electronic switch developed in 1973. Around the same time, scientists at the Tata Institute of Fundamental Research (TIFR), along with those from IIT Bombay, developed a digital Automatic Electronic Switch for the army. These efforts got a boost in 1984 when the government established the Centre for Development of Telematics (C-DOT) by pooling scientific teams from TRC and TIFR under the leadership of Sam Pitroda. The rural telephone exchange developed by Indians could work under harsh conditions and without air conditioning. The technology developed in public sector was transferred for free to private companies, ending the monopoly of multinational giants and rapidly bringing connectivity to rural areas. C-DOT exchange became popular in dozens of developing nations.

IT revolution and railway computerisation: The data processing industry in India during the decades after the independence was dominated by two multinationals – IBM and ICL. The data processing machines of these two firms were in use in the government, public sector, armed forces as well as research institutes. These companies brought old and discarded machines to India and leased them at high rentals. India needed latest computers for applications like National Sample Surveys, nuclear reactor development and other research. In order to break the monopoly of big companies and spur indigenous software and hardware development, the Department of Electronics was established in 1970. Public sector companies like Electronics Corporation of India Limited (ECIL), Computer Maintenance Corporation (CMC) and state electronics development corporations were established. The skills and knowledge thus developed got transferred to private industry. The first major application of information technology was the passenger reservation project of the Railways launched in 1986. It was the largest such project which demonstrated how technology can improve efficiency, cut corruption and touch the lives of millions without the need for them owning a digital gadget.

Blue Revolution: The ‘blue revolution’ refers to adoption of a set of measures to boost production of fish and other marine products. It was formally launched with the establishment of the Fish Farmers’ Development Agency during the Fifth Five-year Plan in 1970. Later on, similar development agencies were set up for brackish water development to boost aquaculture in several states. The objective of all this was to induce new techniques of fish breeding, rearing and marketing, as well as initiate production of other marine products like prawns, oysters, seaweeds, pearls and so on, using new techniques and scientific inputs. Scores of new technologies developed by research institutes under the Indian Council of Agriculture Research (ICAR) have been transferred to fish farmers all over the country. (India Science Wire)

Mega science projects: India poised to join league of global scientific leaders

Leave a comment

Dr T V Venkateswaran

New Delhi: Shedding its hesitant and cautious approach of the past with regard to participating in global mega science projects, India has taken bold steps in recent years to join international scientific quests.

The Science Technology and Innovation policy of 2013 envisages positioning India among the top five global scientific powers by 2020. In addition to home-grown science and engineering projects, the policy advocated participation in global science projects arguing that as a civilised country we must also participate in global mega science projects aiming to find out for example the ultimate structure of matter or the origin of the universe.

Here are some of India’s Big Science initiatives:

Feeling the fabric of space-time: The detection of gravitational waves for the first time in February 2016 after a century of speculation and decades of tenacious attempts to improve sensitivity of instruments to detect these elusive waves, was hailed as the ‘discovery of the century’. Of over 1000 scientists from 15 countries who jointly made this discovery, 39 were from India. Indian scientists made direct contributions – ranging from designing algorithms used to analyse signals registered by detectors to ascertain those from a gravitational wave to working out parameters like estimating energy and power radiated during merger, orbital eccentricity and estimating the mass and spin of the final black hole and so on. Currently there are only two detectors in operation, both in America. Building on their strength, Indian astronomers are proposing to build the third detector somewhere in Maharashtra. Called Indian LIGO (IndiGO), the instrument matching the two LIGO observatories in the US would enable scientists to pinpoint the source of gravitational waves.

Big Bang: India became a full Associate Member of “God particle” fame CERN on January 16, 2017, thereby getting full access to data generated at the world’s largest particle physics laboratory. Currently, CERN has 22 member states. Indian scientists have helped build the Large Hadron Collider (LHC), the most powerful particle collider in the world as well as construction of two significant CERN experiments, CMS and ALICE. Incidentally CMS is one of the two experiments that discovered the Higgs Boson, popularly called as ‘God particle’ and ALICE creates conditions that existed at the time of big bang.

Digging deep: Shivajisagar lake was impounded in the Koyna region in Maharashtra to create an artificial reservoir in 1962. The massive earthquake of magnitude 6.3 that occurred in 1967 brought to light dangers of Reservoir Triggered Seismicity (RTS). Since its construction, the region has witnessed 22 earthquakes exceeding magnitude 5, 200 exceeding magnitude 4 and several thousand smaller earthquakes. Indian geophysicists have drilled a seven-km deep borehole in this earthquake zone and have established an on-the-spot observatory to study earthquakes. The observatory is studying physical and mechanical properties of rocks before, during and after a quake; physical and chemical changes in the earth’s crust that occur during an earthquake; and temperature change that impels melting of rocks. Geologists are hopeful that the knowledge garnered from the web of 15 earthquake sensors and the on-spot data collection, has potential for making earthquake forecasts possible in future.

Making of atoms: India is part of the international Facility for Antiproton and Ion Research (FAIR) coming up at Darmstadt, Germany for studying the building blocks of matter and the evolution of the Universe. This sophisticated accelerator complex will use high-energy, precisely-tailored ion beams to mimic the conditions inside the core of stars and early phase of the universe.

The 1.2-billion euro facility will study the structure of matter and the evolution of the universe since the Big Bang. While the Helium and hydrogen was formed in the early universe, rest of the elements it is postulated were cooked inside the stars. The facility would also shed light on the creation of heavy elements in stars and also the interiors of planets. Indian institutions will be engaged in building NUSTAR (Nuclear Structure, Astrophysics and Reactions), CBM (Compressed Baryonic Matter) and PANDA (Antiproton Annihilation at Darmstadt) in addition to building equipment to be used at the heart of the FAIR accelerator.

Looking back in time: India has joined nine other nations to build the world’s largest and most sensitive radio telescope – Square Kilometre Array (SKA). It will combine signals received from thousands of small parabolic and dipole antennas spread over a distance of several thousand kilometres across Africa and Australia. Karoo desert in South Africa will host the core of the 350 megahertz to 14 gigahertz mid-frequency dish array while the Australian telescope will observe lower-frequency scale, from 50 to 350 megahertz and the total detection area of the receiver dishes would exceed 1 square kilometre. A large number of dipole antennas are capable of receiving very low frequencies while the 3000 odd parabolic antennas operate at higher frequencies. Combining signals from all these thousands of antennas would simulate a single giant radio telescope with extremely high sensitivity. The sensitivity of this radio telescope would be fifty times more than any other radio telescope and it will be able to survey the sky 10,000 times faster enabling astronomers to even capture faint radio signals emitted by cosmic sources billions of light years away from Earth. With such a powerful telescope, astronomers could peer deep into the universe, way back in time when the first stars were emerging.

Shining like Sun: The International-Thermonuclear-Experimental-Reactor (ITER) has embarked upon an ambitious project to build a little bit of Sun in laboratory conduction. While the conventional nuclear reactor breaks a heavy atom like plutonium to gather the binding energy, the fusion reactor will fuse two light elements like say hydrogen into helium to harness the energy. As fusion reactors will not use any radioactive materials, yet generate immense energy, it is considered as a clean-green source of energy. The high temperature in the core of the stars results in light elements becoming highly ionised and attain plasma state. It is in this plasma state that two or more light elements could fuse. If we have to re-create such a condition on Earth, then we need to make a small amount of hydrogen into plasma before we can achieve fusion. One of the challenges is to contain high temperature plasma in a confinement to achieve the fusion. The experimental nuclear fusion reactor being built at Cadarache in south of France hopes to harness fusion reaction to generate energy. European Union, United States, Japan, China, Russia, South Korea and India are jointly building and operating this test facility. Institute for Plasma Research, Ahmedabad is contributing crucial parts of the tokamak reactor’s gigantic cryostat.

Predicting rain: The India Meteorological Department (IMD) is developing a dynamic weather prediction model involving 3D mathematical simulation of the atmosphere on computer and to test variations of dynamic models to ferret out the best ones for operational forecast of rainfall. While the ultimate goal is to get operational weather forecasts at a horizontal resolution of 12 km, by 2019 National Monsoon Mission will provide block level weather forecast. With the improvements in forecast, 24-hour track and intensity forecast error of the tropical cyclones reduced from 141 km to 97 km and ‘landfall error’ from 99 km to 56 km during 2006 to 2015. The accurate forecast of the recent cyclones, Phailin, HudHud and Vardah saved thousands of human lives.

Churning the sea: Using research vessel, Gaveshani, Indian researchers had collected samples of poly metallic nodules from Arabian Sea in 1981 and India was given a pioneer area for exploration of deep sea minerals in the Central Indian Ocean Basin in 1987. Subsequently extensive surveys were carried out leading to allocation of an area of 150,000 sq km with exclusive rights under the UN Law of the sea. India has access to an area of 75,000 sq km with an estimated resource of about 100 million tons of strategic metals such copper, nickel, cobalt besides manganese and iron. As various national institutions have developed technologies for extraction of metals from the minerals, soon India would establish First Generation Mine-site (FGM) with an area of 18,000 sq km and harvest natural resources from the sea-bed. The multi-purpose deep ocean mission would also try to harness deep ocean energy, deep sea fishing along with deep sea mining. Further technologies for sea water desalination to obtain potable water would also be undertaken.

Looking deep: The Thirty Meter Telescope (TMT), world’s advanced ground based telescope, is expected to outsmart all ground-based telescopes once it is operational. Made of 492 individual segments, the telescope mirror would have a reflective diameter of 30 meters and would be 81 times more powerful than any other telescope. It a partnership project involving CalTech, Universities of California, Canada, Japan, China and India. While initial location chosen was Hawaii, Hanle in Ladakh was also considered as an alternative. However, it may perhaps be finally located in Chile. Building of such a massive telescope is a technological challenge. The mirror segments have to be aligned precisely with each other and the adoptive optics proposed would eliminate the twinkling effect caused by atmospheric thermal disturbances. India will develop and manufacture 15% of the mirror segments and assembly.

Reaching for stars: India had dazzled the world by reaching Mars in very first attempt. Indian spacecraft reached the moon before that. Currently AstroSAT a multi wavelength space telescope is operational. ISRO in coming years would add many more deep space missions to its credit. Chandrayan 2- with a lander and rover is proposed to be launched some time inn 2018-19. A mission to study the Sun – Aditya, is in the offing. Building upon the success of the Mars Orbiter Mission, ISRO is planning to send yet another spacecraft to study Mars. Indian space programme in addition to providing telecom, weather, navigational services, would also take a pride of place among the spacefaring nations of the world.

Technological spinoffs of mega projects such as LHC or FAIR are immense. Technology developed in CERN went into making mammograms used for breast cancer detection, while the positron used in particle physics experiments gave us PET (Positron Emission Tomography). The study of fundamental particles is sure to yield newer imaging technologies. That’s why it is important to invest in mega science projects. (India Science Wire)

Acting on a tip-off, Army, Special Operations Group of the Jammu and Kashmir Police, and the CRPF cordoned off Awnira village of Shopian on Satuday night. Encircled by the security forces, the terrorists opened fire injuring 5 Army personnel, two of whom later succumbed to their wounds. The security were that were engaged in several rouns of firing through the night launched a major strike in the morning and all the the three terrorists holed up in the village were killed.

Besides Gaznavi, the two other killed were Irfan, who was the mastermind behind the online propaganda for Hizbul Mujahideen, and Umar, who was personal security man of Ghaznavi.

Itoo, from Budgam district of central Kashmir, had joined Hizbul Mujahideen in 1996. He was one of the main persons behind the prolonged disturbances in Kashmir following the killing of Burhan Wani in 2016. He was also instrumental in a big way in recruiting young men into the terrorist outfit.
