NEW DELHI: G. M. Saxena has spent most time on clocks. As his last project, the physicist who retired from the Time and Frequency Division of the National Physical Laboratory, New Delhi, this year, headed a team that has created the “physics package” – really the critical part – of the Rubidium atomic clock in India. The working of an Rb atomic clock, used most commonly in GPS satellites, is not exactly common knowledge. In fact, very few countries possess the technology and those who do, guard it zealously……

With the kilogram “shedding and gaining” weight over the last 100 years, India has now proposed a new method to maintain its accuracy. At present, India has “artifact-based national standards” for the kilogram. The National Physical Laboratory (NPL-CSIR), Delhi, has proposed instead the “levitated superconductor” approach during the 12th Five-Year Plan to give a new definition to the kilogram….

ELURU: G. Bhavanarayana, Scientist-G of the National Physical Laboratory at New Delhi, on Friday underlined the need for the country to attain energy security by way of exploiting energy through alternative renewable resources with the help of technologies.
Delivering the key-note address at a seminar on “Recent trends in advanced materials” held here under the joint auspices of the departments of Physics and Chemistry of Sir. C.R. Reddy College, he said the country required to generate energy in adequate quantities to put the technologies to use to the hilt. “Our conventional energies resources such as petrol, diesel, coal etc are going to be exhausted soon”, he observed. The impending energy crisis has necessitated the need to shift to the non-conventional energy resources like hydel energy, wind energy, geothermal energy, tidal energy and bio-energy, he added. “Production of hydrogen through water and its storage in a solid form could be another possible alternative”, he said….

VARANASI: At a time when weather experts and environmentalists around the world are worried about the repercussions of climate change due to global warming, a young scientist from National Physical Laboratory (NPL), New Delhi, contrarily believes that the world is gearing to face ice age conditions, may be after 500 years. And, he has strong reasons to justify his stand as he believed that more than natural disasters including climate change, it is the man-made disaster that would bring such conditions sooner than later.
“We are already witnessing one of the coldest April month in the last one decade this year and human interference and its continuous fight with nature is going to bring conditions that would promote situation like an ice age where icy winds would be common, said Alok Mukherjee, young scientist from NPL and scientific secretary, South Asian START committee, Centre on Global Change while talking to TOI on Friday. Ruling out the worries about glacier meltdown across the globe that threatens to increase sea level putting the existence of a number of island nations in the world including Bangladesh under risk, he emphasised that it is not the glacier melting but the tilting of Bangladesh due to continental drift making the sea level to rise from one side……

CHENNAI: Around 3,71,600 tiny vials of the indelible blue ink are stacked up at a paint factory at New Bannimantap Extension in Mysore. It will be used on the fingers of several thousand citizens who cast their votes in the forthcoming assembly elections in Tamil Nadu, West Bengal, Kerala, Assam and Puducherry.
…..Mysore Paints managing director K J Suresh said on Tuesday that by the weekend 1.01 lakh vials will be delivered to Tamil Nadu. Kerala needs 49,200 vials and Assam 57,400 vials.
Voters’ ink or indelible ink has been used since the third general elections in 1962. Developed by the Delhi-based National Physical Laboratory, the ink’s manufacturing has been licensed by the state-run National Research Development Council to Mysore Paints, a 74-year-old company owned by the Karnataka government. The company also dispatched ink to Burkina Faso, the Solomon Islands and Maldives earlier this year. “The PSU has gone hi-tech both in production and packaging. This has resulted in quick service,” Suresh said…..

The Brihadeeswarar temple, Thanjavur, will soon have a sound-and-light show. The plan now is to have two shows each day – one in English and the other in Tamil – and the duration is expected to be about 45 minutes each.
After a long struggle, and coordinated efforts of the Tamil Nadu Tourism department and personal interest of Chief Secretary K.S.Sripathi, the decks have finally been cleared for the show. A Memorandum of Understanding was signed on July 8 between the Director General, Archeological Survey of India and the Managing Director, Tamil Nadu Tourism Development Corporation, signalling the formal completion of procedures ahead of putting up a show.
The temple, dedicated to Lord Shiva and built by Rajaraja Chola (985-1012), is a UNESCO recognised world heritage site. Hence, though the Tourism department had thought of the sound and light show around the same time that it introduced the show at the Tiumalai Nayakar Mahal at Madurai, a series of steps needed to be completed ahead of the commencement of the event.
“The temple is a protected monument. So the ASI wanted acoustic and light effect studies carried out ahead of giving us permission,” said Tourism Secretary V.Irai Anbu.
This took time. The National Physical Laboratory deputed its experts to investigate the effect of “induced vibrations due to acoustic excitation form the sound show” at the temple…….

NEW DELHI: The ball has finally set rolling for erection of a sound-proof steel barrier covering the rail tracks close to Commonwealth Games Village near Akshardham temple here keeping the athletes’ comfort in mind.
The work on the Rs 2 crore project, which got delayed for more than a year due to various reasons, will start from tomorrow.
The sound-proof barrier will cover the tracks for half a km. The stretch is considered one of the busiest in the country emanating noise levels touching 65 decibel.
Since the tracks are near to the Games Village, the sound of passing trains may pose a problem for athletes, especially in the night when the noise level is the maximum.
The concrete steel barrier of three metres height will reduce the noise level to about 25 decibel, a senior DDA official involved in the project said.
“We have awarded the contract to Lloyd Insulations (India) for constructing the 500-metre long sound-proof barrier near Games Village,” he said.
About the delay, he said, the change in design and lack of response to the first tender were the main reasons.
“We had to make some changes in the tendering documents to get suitable bidders. However, now that the project is on track we are expecting to complete the work by September 15,” he said.
DDA is constructing the sound-proof barrier with assistance from the National Physical Laboratory (NPL) and the Central Pollution Control Board (CPCB)………
