Indian
Scientist Develops Solar Vaccine Cooler
|
| |
|
Resurgence of polio in parts of India could
be attributed to faulty storage of vaccines,
but an Indian scientist has invented a solar
vaccine cooler for use in rural parts where
electricity is in short supply. SolarChill,
a vaccine cooler developed by Rajendra Shende
under the United Nations Environment Programme
(UNEP), promises to be viable eco-friendly
solution, which replaces the lead batteries
and the ozone depleting chloro-fluro-carbons
used in conventional refrigerators. Paris-based
Shende, the head of UNEP's OzonAction Branch,
is in the capital to deliver two units of
SolarChill to its first Indian customer
-- President A P J Abdul Kalam, who proposes
to intall them at the clinic in the Rashtrapati
Bhavan complex. "SolarChill does not use
lead batteries or kerosene used in conventional
solar chillers. Instead, we use the sun's
energy to create a thick layer of ice which
helps in maintaining temperature in the
cooler between minus two degrees and eight
degrees celsius," Shende told PTI. Shende
hit upon the idea during his travels in
Burkina Faso in 2000. "I thought that if
we could develop a vaccine cooler that uses
the solar energy so abundant in Burkina
Faso and other developing countries, it
would be a boon for vaccination programmes
implemented there," he said. Shende said
he thought of an affordable, eco-friendly
version of solar coolers as he was already
working with WHO on ozone depletion. "As
the lead batteries are toxic, difficult
to carry, and need replacement every three
to five years, we decided to utilise to
create ice box within the refrigerator that
will provide the required insulation even
during night," Shende said adding in the
absence of the sunshine, SolarChill can
sustain for four to five days. He said the
cooling unit, too, did not use regular freon-based
chemicals, which deplete ozone and add to
global warming. One unit can serve the vaccine
needs of some 50,000 people. The units will
be available for commercial manufacture
by 2007, Shende said. Shende's idea was
jointly taken up by UNEP, UNICEF, WHO, the
Danish Technological Institute, Greenpeace,
GTZ Proklima, and Programs for Appropriate
Technologies in Health (PATH). Refrigeration
companies Vestfrost and Danfoss took part
in the development of SolarChill, which
took place in Senegal, Indonesia and Cuba.

India
does its 1st Cryogenic Rocket Test
|
| |
|
In
a major breakthrough in its space programme,
India on Saturday, successfully conducted
the first test of its indigenously developed
cryogenic rocket engine at a facility at
Mahindragiri in Tamil Nadu. "We had a very
successful first cryogenic stage test at
Mahindragiri at 6:20 pm. It is a major milestone
in the development of rocket systems in
the country," Indian Space Research Organisation
Chairman G Madhavan Nair said. The test
at ISRO's Liquid Propulsion Centre at Mahindragiri
lasted for 50 seconds, he said. "Only developed
countries have this stage. We have also
qualified now," Nair said. "We will go for
one more long duration test in the next
three or four weeks which will make it ready
for flight." The cryogenic rocket engine
that ISRO successfully tested on Saturday,
was equivalent to the "Russian stage" supplied
earlier, Nair said.

Kalam
Backs New Solar-Powered Fridge, an Indian
Brainchild
|
| |
|
An
idea that germinated on the dusty streets
of Ougadougou, the capital of Burkina Faso,
in the mind of a prominent Indian scientist
will finally see fruition this Wednesday
when Indian President APJ Abdul Kalam becomes
the first global citizen to acquire two
refrigerator-cum-vaccine coolers, totally
powered by the sun. The SolarChill uses
a breakthrough technology aimed at making
the process of refrigeration accessible
even to the remotest parts of the world
and hence help several social causes like
the vaccination projects of the World Health
Organisation and the United Nations Children's
Fund (UNICEF). Rajendra Shende, the head
of the OzonAction Unit of the United Nations
Environment Programme and the brain behind
the idea, remembers clearly the moment when
the idea struck him -during a bus ride in
the western African nation of Burkina Faso
in 2000. "Looking out of our bus window
at the children of the rural poor and thinking
about their fragile health, it occurred
to me that plenty of sunshine does not mean
plenty of health. Some children, carrying
their sick younger brothers and sisters,
were looking at us as if we were from other
planets. "I thought that if we could develop
a vaccine cooler that uses the solar energy
so abundant in Burkina Faso and other developing
countries, and if we develop a vaccine cooler
that uses the solar energy so abundantly
available there, and non-CFC (ozone-friendly),
non-HFC (climate-friendly) refrigerants,
it will be an environmentally perfect product,"
Shende said in Paris, just before leaving
for New Delhi for the high-profile acquisition
by the Indian president who has been keeping
a close tab on the breakthrough development.
Shende
says that the president has been keenly
following the progress of the project ever
since he heard about it over a year ago.
"When I informed him about the project,
he was very keen and requested me to keep
him informed on the progress. The president
could see the huge importance of SolarChill
for the developing countries, particularly
in saving the lives of the rural children
and women who do not have access to electricity
and effective vaccines," recalls Shende.
And when the project was finally complete
and the team was looking for high-profile
platforms for the launch of the project,
Kalam was the unanimous choice. "It was
found to be important to get SolarChill
known to the world community. I recalled
my discussions with the president in 2005
and wrote to his office. I was immediately
informed that the president is not only
keen to install and operate two units in
the clinic of the presidential complex (around
Rashtrapati Bhavan) but was very keen to
buy these units and not to get them free,"
says Shende. The first use of the SolarChill
is for facilitating the preservation of
vaccines in far-flung and remote areas that
don't have access to not only electricity
but also other fuels like kerosene. The
vaccine coolers so far being used in immunization
programmes work inefficiently due to non-availability
or inadequate supply of grid electricity.
Even when kerosene is used for the vaccine
cooler, supply of kerosene is not certain
in many areas and moreover kerosene is also
a contributor to global warming and pollution.
The technology has already made waves around
the world, winning the prestigious 2006
Cooling Industry Awards in the category
"Environmental Pioneer" for refrigeration
in London earlier this year. The project
is truly international since it involves
a total of seven international organisations
from all over the world. Besides the UNEP,
the partners in the project include Greenpeace
International, UNICEF, World Health Organisation
(WHO), GTZ Proklima, Programmes for Appropriate
Technologies in Health (PATH) and the Danish
Technological Institute. Shende is obviously
thrilled by the success of the project.
"Receiving the Cooling Industry Awards is
an important statement by industry leaders
in refrigeration and air-conditioning that
they recognize the importance, innovation
and societal benefits of SolarChill. UNEP
and the other partners would like to thank
the organizers and the jury panel members
for this award."
Over
the last six years, the partnership has
developed a versatile refrigeration technology
that operates on solar energy; uses environmentally
safe refrigerants, bypasses the use of lead
batteries, and can also be plugged into
the electricity grid. SolarChill is applicable
for emergency relief in natural or human
made disaster zones. It has been field-tested
in Cuba, Indonesia and Senegal. The SolarChill
technology is publicly owned and will soon
be freely available for any company in the
world interested in producing the units.
Once it receives WHO approval, the Partners
will work with interested refrigerator manufacturers,
ministries of health and environment, foundations
and others to have it commercialised and
deployed across the globe. Shende says that
though solar refrigeration per se is not
a new concept, SolarChill is a real breakthrough.
What the SolarChill partnership was trying
to achieve is to adopt the concept for vaccines
preservation and making it simple for use
in rural, remote and least developed areas
where electricity is not available or where
the electric supply is irregular. Such situation
causes the efficacy of the vaccines to diminish.
Hence even administered vaccination programmes
may not achieve their goals. The partnership
also decided to avoid the need to convert
the direct current (DC) solar electricity
to alternate current (AC) electricity by
designing the DC motor that would run the
compressor. The need for the storage batteries
was also to be done away with by designing
the effective insulation that would maintain
the temperatures to keep the vaccines effective
during the night when solar light is not
available. The product was developed in
four years, through collaborative efforts,
field-tested and is now undergoing WHO approval
process. "The power of partnership has produced
the product that is pro-poor. Power of nature
could be nurtured to improve the way we
make choices for the sustainable development.
For the first time in the history of technology
transfer the partnership of seven international
agencies, and NGOs and technical institutes
has developed a technology that is in public
domain. It would be made available to those
who wish to use it," says Shende.

40
Million Indian Internet Surfers Expected
by March 2007
|
| |
|
The
burgeoning population of Internet users
in the country has opened up a large market
for search engine companies. According to
a recent study conducted jointly by the
Internet and Mobile Association of India
(IAMAI) and IMRB International, a research
organisation, the Internet user base in
India is likely to cross the 40-million
mark by March 2007. "Next to mobile phones,
I think Internet is one of the more accessible
and sticker medium. That is what is going
to drive the use of advertisers of the medium
in the market," said IAMA President Dr Subho
Ray. With the increasing number of internet
users in India, the medium has become yet
another platform for marketing with tremendous
growth potential which is yet to be fully
tapped. "Somebody is looking for information
on car... say, a marketer. I want my results
to be shown when that person is looking
for information of the car, because I am
getting the right person at the right time.
This kind of advertising is called the search
engine advertising. And it's growing tremendously
in the last few years in India," said Pinstorm
Founder and CEO Mahesh Murthy. "Online advertising
has come to about four to five percent of
the entire advertising spent. The Indian
market which is rupees 15,000 crores, the
spent could be Rs 600 crore. It's a 150
million dollar right now and the market
that is growing overtime. So, it's tremendously
large size but its not just market within
India that is really important. The other
important thing is that lots of Indian companies...
Just like world outsourced to India. The
world is beginning to outsource marketing
services to India," added Mahesh Murthy.
According to the study, some of the big
spenders on search engine advertisings aimed
at the Indian audience are Naukri, 99acres,
Jeevansathi, eBay, Monster and JobsAhead
whose total annualised spending amount to
52 million dollars. The study also found
that over one billion searches are made
in a month, with over 300 million searches
with ads on them and with almost five million
clicks on advertisements every month.

Now,
Get Disaster Alerts on your Cell
|
| |
|
India's
remotest villages will now be better prepared
to face another tsunami or any natural calamity.
A Bangalore-based private software company,
Geneva Software Technologies, along with
the ministry of science and technology has
developed the world's first-of-its-kind
multilingual disaster alert system Natural
Disaster Information System (NDIS) that
will transmit tsunami and cyclone warning
through mobile phones in the form of SMS,
within 30 seconds of a weather satellite
or an earthquake observatory giving an alert
signal. The SMS alerts will be sent in over
100 languages, including 14 regional languages
like Tamil, Kannada, Telugu, Bengali, Malayalam,
Hindi and Oriya. The SMS alerts will be
followed by voice alerts on the mobile phones
as well as fixed phones. Till now, all disaster
alert systems have failed because most warnings
are conveyed through TV and radio which
could be switched off, alerts are mostly
in English, multi-lingual disaster alert
systems are complex as it requires GPRS
and high-end Java phones and users need
to subscribe for the service. Interestingly,
with NDIS, the messages will reach any mobile
without the need to download alert applications
and fonts and works on even basic handsets.
The multi-lingual messaging software used
by NDIS is compatible with most types of
cellphones used in Asia and is compact enough
to be stored on a subscriber identity module
(SIM) card. Science and technology ministry
contributed $880,000 to the product's development.
This is how it works: The NDIS server first
receives the warning from the meteorological
department alert system before converting
it into an SMS in two seconds. In the next
19 seconds, the software translates the
alert into multiple languages. In 30 seconds,
the SMS reaches the user. S&T minister Kapil
Sibal said, "This is an amazing technology.
It could help people in the time of disasters
like tsunami. It will take some time before
the SMS alerts facility is made available
to the common man. "The proposal has been
sent to the ministry of home affairs, which
is the nodal ministry for handling disaster
management." Existing text-messaging technology
requires that both sender and receiver have
devices that use Unicode, the standard international
system for representing characters on a
digital screen. But in rural areas of developing
countries, few people can afford Unicode-compliant
handsets.

Sun
in 3-D: a New Frontier in Solar Research
|
| |
|
An
artist's rendition of the STEREO spacecraft
panels suggests its path into orbit. The
twin observatories will fly as mirror images
of each other to obtain unique "stereo"
views of the sun's activities. (Credit:
NASA/Johns Hopkins U. Applied Physics Lab)
NASA's
Solar TErrestrial RElations Observatory
(STEREO) spacecraft - the first mission
designed to capture the sun in 3-D - successfully
launched at 8:52 p.m. EDT on October 25,
2006, aboard a single Delta II vehicle from
Cape Canaveral Air Force Station, FL. The
two nearly identical spacecraft, designed,
built and operated for NASA by the Johns
Hopkins University Applied Physics Laboratory
(APL), in Laurel, MD, separated from the
launch vehicle 25 minutes after lift-off.
After receiving the first signal from the
spacecraft 63 minutes after launch, mission
control personnel at APL confirmed each
observatory's solar arrays successfully
deployed and were providing power to the
spacecraft. The initial radio signals were
forwarded to the APL-based STEREO Mission
Operations Center from NASA's Deep Space
Network antennas in Canberra, Australia.
During a two-year mission, the twin observatories
will explore the origin, evolution and interplanetary
consequences of coronal mass ejections.
These powerful solar eruptions are a major
source of the magnetic disruptions on Earth
and a key component of space weather, which
can greatly affect satellite operations,
communications, power systems, and the lives
of astronauts in space.
Placing
STEREO into Orbit
For the next few weeks, the spacecraft will
fly in an elliptical orbit that extends
from Earth to just beyond the moon. During
this time, mission operations personnel
at APL will place the spacecraft in flight
mode, turn on and check out all instruments
and subsystems, and ensure all systems are
operating nominally in preparation to begin
their data collection efforts. In approximately
two months, mission operations personnel
at APL will synchronize spacecraft orbits
and direct one observatory to its position
ahead of Earth. In approximately three months,
the second observatory will be redirected
to its position trailing Earth. Just as
the slight offset between your eyes provides
you with depth perception, this placement
will allow the STEREO observatories to obtain
3-D images and particle measurements of
the sun. During lunar swingbys, the spacecraft
will use the moon's gravity to redirect
themselves to their appropriate orbits -
something the launch vehicle alone can't
do. This is the first time lunar swingbys
have been used to manipulate orbits of more
than one spacecraft. Each STEREO observatory
is carrying two instruments and two instrument
suites, providing more than a dozen instruments
per observatory. APL designed and built
the spacecraft platform housing the instruments.
When combined with data from observatories
on the ground or in space, STEREO's data
will allow scientists to track the buildup
and liftoff of magnetic energy from the
sun and the trajectory of Earth-bound coronal
mass ejections in 3-D.

NASA
Conducts Mission to Study Sun Eruptions
|
| |
|
Twin
spacecraft known as STEREO, for Solar Terrestrial
Relations Observatory, lifted off on Thursday
on a two-year mission will help them understand
why these eruptions occur, how they form
and what path they take.
Twin
spacecraft blasted off from Cape Canaveral
in Florida early on Thursday, on a mission
to study huge eruptions from the sun that
can damage satellites, disrupt electrical
and communications systems on Earth and
endanger space walking astronauts. The two
spacecraft, known as STEREO, for Solar Terrestrial
Relations Observatory, lifted off on Thursday,
stacked one on top of the other, aboard
a single Delta II rocket. The lift off was
delayed by several minutes after launch
managers became concerned late in the countdown
that winds could blow toxic material over
populated areas should there be an accidental
explosion. However, the winds became acceptable
about 15 minutes before launch, permitting
the rocket to soar off the launch pad with
a roar. Scientists hope the 550 (m) million
US Dollar, two-year mission will help them
understand why these eruptions occur, how
they form and what path they take. The eruptions,
called solar flares, typically blow one
(b) billion tons of the sun's atmosphere
into space at a speed of one (m) million
miles per hour (1.6 million kilometres per
hour). The phenomenon is responsible for
the Northern Lights, or aurora borealis,
the luminous display of lights seen in the
upper latitudes of the Northern Hemisphere.
The two observatories will provide scientists
with the first-ever three-dimensional view
of the sun by working in tandem, like a
set of eyes, in different orbits. NASA hopes
information about the solar flares helps
the astronauts who fly to moon and eventually
Mars in the coming decades. Astronauts exposed
to the eruptions can receive a year's worth
of radiation. The spacecraft's launch was
delayed several times this year because
of technical problems. Scientists plan to
release movies and other images created
by the STEREO spacecraft to the public,
though viewers may need to use the type
of 3-D glasses worn for special movies.

VSNL
to Lead India-Europe Submarine Link Project
|
| |
|
Tata
group seems to be on a roll. Its long-distance
telephony and Internet services firm Videsh
Sanchar Nigam has forged an alliance to
construct a high capacity submarine cable
linking India, West Asia and western Europe.
Expected to be commissioned in mid-2008,
the link will ensure availability of telecom
and Internet bandwidth, demand for which
is growing at an exponential pace. The over
10,000 km cable, connecting Mumbai with
France, will cost the consortium of five
players including VSNL to the tune of $350-400
million. A company source says VSNL will
be the biggest shareholder in the network
with an investment of up to $150 million
over the next 18 months giving it managerial
and operational control. Etisalat, Saudi
Telecom, Telecom Egypt and Telecom Italia
Sparkle and VSNL have signed a memorandum
for the construction of the network. The
move comes at a time when bandwidth requirement
in India is expected to grow at 70% in the
next five years. Bandwidth demand in West
Asia is also growing at 70-80% and there
is a spurt in demand from North Africa on
the back of substantial growth in mobile
telephony. Says a VSNL executive, "The expansion
is to ensure that we are ready with new
capacity when the additional demand comes
in." Industry specialists say despite adequate
capacity available in India, new bandwidth
is necessary as enterprise customers like
telecom and Internet-based businesses buy
up more than one link to build redundancies
in the system. Globally, it is a norm to
have bandwidth capacities of 2.5-3 times
the actual demand because of multiple backup
requirements of customers. There is also
belief that the increasing FDI in and out
of the country will also bring in new demand
for bandwidth from firms. For example, it
is expected that Tata Steel which recently
announced acquisition of Corus will buy
international bandwidth to set up communication
links between India, UK and Netherlands.
The system that will connect India, UAE,
Saudi Arabia, Egypt, Italy and France is
expected to be ready by mid-2008 and the
construction contracts will be awarded in
the next two months. It will have proposed
design capacity of at least 2.56 terabits
per second.

This
gadget has gone from select luxury to mass
necessity in no time. Only to get charged
with ever newer paradoxes.
It
is estimated that India has more than 130
million mobile phone owners today. That
is a 130 million more than there were eleven
years ago, in 1995, when the first mobile
phones were introduced in Delhi.
A
large number of the people who own a mobile
in India today are probably those who have
never had a phone of their own before. For
most of them, the mobile phone is their
first intimate connection with telephony.
It does not sit, like the old bakelite telephones
used to, on something that could almost
be called an altar-in homes, shops or offices,
often placed under protective lock and key.
Instead,
it travels in pockets where it forms suggestive
bulges, or is flashed out of handbags like
an alluring accessory. It sings, it emits
light, it spies, is spied upon, takes pictures
and writes poetry. It offers everything
from sage advice to pornography. It is a
node in a social network, a diary, a music
machine, a shop, a gambler's addiction,
a confessional and a betrayer. It gleams
down at us from illuminated billboards on
flyovers. It drives the plot line of the
latest movie, changes the course of a cricket
match, and transforms political fortunes.
Nowadays, we even measure our days and nights,
as well as our meagre incomes, by 'talk
time'.
Before
the '90s of the last century, the telephone
god was a remote and formidable deity. It
took seven years to bring a phone home,
ten minutes to get to a phone (perhaps to
a neighbourhood phone booth) and five minutes
(or more, depending on the state of the
exchange) to get through to the person you
wanted to speak to. It never took long to
hang up. There is no reason to look back
on those decades of disconnect with anything
remotely resembling nostalgia, if anything
it should prompt us to look at our own more
'connected' time with care and acuity.
The
recent global mobile phone boom is directly
linked to the wars that have devastated
Central Africa, which holds the largest
reserves of coltan, a mineral used in the
manufacture of mobile phones and laptop
computers. The reason why this becomes vital
to think about is the fact that some of
the companies involved in the mobile phone
boom that is currently under way in India
have been named by human rights groups and
UN investigating agencies as having directly
benefited from Central African coltan wars.
A mobile phone isn't just a device a politician
uses to talk to his paramour, it isn't just
the cool new gadget that lets you play a
hundred tunes or snap your dog's pictures-it's
generalised usage within information-hungry
societies such as ours, a provocation for
thinking about many things that one doesn't
automatically associate with the ephemera
of phone calls. These can include the political
economy of technology, ownership and monopoly
issues, the tragic reality of distant and
enduring wars as well as the uncomfortable
proximity of surveillance.
Amongst
the things that the mobile phone made possible
in India was a dramatic increase in all
sorts of formal as well as informal surveillance
processes. Phone tapping had always lurked
as a tool of political control, but the
mobile phone made telephonic surveillance
far more generalised than it had ever been
before. The unsuccessful prosecution case
against S.A.R. Geelani in the December 13
Parliament attack case was entirely based
on the manipulation of transcripts and translations
of illegal mobile phone interceptions made
by the Delhi Police.
If
one reads the court records carefully, it
becomes apparent that the police and other
investigating agencies (and their personnel)
routinely resort to mobile phone surveillance,
with the collusion of the phone companies,
for all sorts of reasons that range from
the flippant and the banal (a little 'freelance'
detective work on the side to satisfy suspicious
husbands about the call records of their
wives) to the paranoic and the bizarre (generally
to do with the chimera otherwise known as
'national security'). The mobile's promise
of an unhindered liberty of conversation
between ordinary people is shadowed by the
lengthening shadow of the nosy-nanny state.
In
fact, thinking about the mobile phone opens
up a series of contemporary paradoxes. The
mobile phone in Indian cities sits across
a strange intersection, where decades of
artificially and arbitrarily maintained
telephone scarcity meet a new consumerist
hysteria, where anxieties about privacy
meet new public intimacies. We see it advertised
both as a status symbol as well as a basic
need. It becomes a measure that protects
young single women in the city who now travel
freely after dark knowing that they can
always call for help if harassed or attacked,
as well as a means with which men attack
and violate women by circulating images
taken with mobile phone cameras without
prior consent.
The
mobile phone and its increasingly ubiquitous
presence in our lives demand that we think
carefully not only about the information
that politicians share with each other on
their mobiles but also about the politics
of information itself. This becomes necessary
because our intimate conversations are no
longer protected from scrutiny, because
our images can travel from hand to hand
without our consent and because our sense
of privacy is constantly violated by the
unwelcome attention of the tele-marketeer,
the phone spammer and the phone stalker.
In these circumstances, the very political
question of who has the authority to speak,
and who has the power to listen in on what
gets said, becomes the very personal question
of what happens when you take a call on
your mobile. Think carefully the next time
you hear an annoying or pleasing ringtone,
or the next time your caller ID flashes
on someone else's phone. Do you want to
take, or make, this call?

DRDO
Must Get its Act Together: Services Brass
|
| |
|
The
armed forces' brass had two specific messages
for PM Manmohan Singh on Wednesday. One,
corruption scandals in defence deals should
not be allowed to derail modernisation plans.
And two, DRDO must get its act together,
instead of delivering too-little, too-late.
Sources said the PM was told during the
combined commanders' conference that long
delays in procurement of desperately-needed
military hardware and software, coupled
with tardy progress in DRDO projects with
unrealistic timeframes, was causing a steady
depletion in the war-waging potential of
the armed forces. Navy chief Admiral Arun
Prakash, for instance, stressed that episodes
like the recent CBI kickbacks case in the
Rs 1,160-crore Barak deal would send the
wrong message that it's better to avoid
taking decisions rather then they coming
back to haunt you later, said sources. Any
paralysis in decision-making would not augur
well for the future of India's defence preparedness,
he said. The Navy, of course, is quite upset
that one of its former chiefs, Admiral Sushil
Kumar, has been named as an accused by CBI
for legitimately favouring the top-notch
Israeli Barak-I anti-missile defence system
in 1999-2000 over the still-unsuccessful
indigenous Trishul system.
IAF
chief Air Chief Marshal S P Tyagi, in turn,
pointed to the long delays in the indigenous
'Tejas' Light Combat Aircraft, as well as
the acquisition process for 126 multi-role
combat aircraft from abroad, to buttress
this point, said sources. Grappling as it
is with a rapidly-depleting fighter strength,
the IAF will lose its long-standing combat
edge over Pakistan in a few years from now,
warned ACM Tyagi Pakistan, as it is, is
on course to get 36 or more advanced F-16s,
apart from upgradation of its existing 32
F-16s, from the US. This will be supplemented
by a large number of JF-17 'Thunder' fighters
jointly developed with China. The PM, on
his part, said the government would ensure
a "balanced development"of the country's
defence capabilities.In pursuing the modernisation
of the armed forces, "we seek the optimal
blend of developing and producing indigenously
and sourcing from elsewhere". "Transparency
in procurement is a desirable objective,
both for good governance and national security.
Reports critical of such processes can demoralise
the Services, where they are untrue, and
must be directly addressed, where they are
true,"he said. The forces certainly need
reassurance that the frequent eruption of
defence scandals will not hit their modernisation
plans.

New
Image Gives Insight into Colliding Galaxies
|
| |
|
A
seemingly violent collision of two galaxies
is in fact a fertile marriage that has birthed
billions of new stars, and an image released
on Tuesday gives astronomers their best
view yet. The new image of the Antennae
galaxies allows astronomers working with
the orbiting Hubble Space Telescope to distinguish
between new stars and the star clusters
that form them. Most of these clusters,
created in the collision of the two galaxies,
will disperse within 10 million years but
about 100 of the largest will grow into
"globular clusters" -- large groups of stars
found in many galaxies, including our own
Milky Way.The Antennae galaxies, 68 million
light years from Earth, began to fuse 500
million years ago.A light year is the distance
light waves travel in one year -- about
6 trillion miles.The image serves as a preview
for the Milky Way's likely collision with
the nearby Andromeda Galaxy, about 6 billion
years from now.

Radar
Helps Locate Meteorite in Kansas
|
| |
|
Scientists
were excited when they pulled a 154-pound
meteorite from deep below a Kansas wheat
field, but what got them most electrified
was the way they unearthed it. The team
Monday uncovered the find 4 feet under a
meteorite-strewn field using new ground-penetrating
radar technology that someday might be used
on Mars.It was that technology which pinpointed
the site and proved for the first time that
it could be used to find objects buried
deep in the ground and to make an accurate
three-dimensional image of them. "It validates
the technique so we can use something similar
to that instrument when we go to Mars,"
said Patricia Reiff, director of the Rice
Space Institute. Such GPR systems had been
used in the past to locate smaller meteorites
through the ice in Antarctica. But until
the Kansas dig, the technology had not been
successfully used for ground detection in
heavy soils - like on Mars - to find meteorites
or water there. The dig was likely the most
documented excavation yet of a meteorite
find, with researchers painstakingly using
brushes and hand tools to preserve evidence
of the impact trail and to date the event
of the meteorite strike. Soil samples also
were bagged and tagged and organic material
preserved for dating purposes. "When we
find a piece of meteorite, each one is a
new sentence we add to the book to understand
the evolution of the solar system," Essam
Heggy, planetary scientist at the Johnson
Space Center's Lunar and Planetary Institute
in Houston. Even before they had the pallasite
meteorite out of the ground, the scientific
experts at the site were able to debunk
prevailing wisdom that the spectacular Brenham
meteorite fall occurred 20,000 years ago.
Its location in the Pleistocene epoch soil
layer puts that date closer to 10,000 years
ago. "We know it is recent," said Carolyn
Sumners, director of Astronomy at the Houston
Museum of Natural Science, as she surveyed
progress on the dig. "Native Americans could
have seen it."
The
expedition was put together by the Houston
Museum of Natural Science and led by meteorite
hunters Steve Arnold and Philip Mani. Johnson
Space Center's Lunar and Planetary Institute,
the Rice Space Institute at Rice University
and George Observatory in Houston also sent
researchers. Fewer than 1 percent of the
meteorites discovered on earth are pallasite
meteorites, known for their crystals embedded
in iron, Mani said. Sophisticated metal
detectors at the site initially detected
what had been thought to be the largest
pallasite meteorite ever discovered. But
ground-penetrating radar showed that the
object was only a steel cable. The Brenham
field was discovered in 1882. Scientists
have since traced pieces of the shower as
far away as Indian mounds in Ohio, indicating
the meteorites were traded as pieces of
jewelry and ceremonial artifacts. The site
was largely forgotten in recent decades
until Arnold and Mani leased eight square
miles of it and began looking deep below
the surface. More than 15,000 pounds of
meteorites have been recovered from the
area. This week's find will end up as part
of a new exhibit on comets, meteors and
asteroids at the Houston Museum of Natural
Science. The museum will pay about $50,000
for it, Sumners said. It is valued at more
than $100,000, she said. Landowner Alan
Binford watched with interest as the scientists
freed the meteorite, bagging clumps of his
rich Kansas farmland around it."I didn't
figure there would be that much scientific
value," he said. "I never thought about
them going to this extent. It is interesting
history."

India
Starts to Prepare Hazard, Risk Maps
|
| |
|
India
has launched a major initiative to prepare
hazard, risk and vulnerability maps at microscale
for early warning and effective disaster
risk reduction and management. The move
to have microscale maps is to make the task
of risk assessment and analysis much more
accurate and fast. This assumes significance,
as natural calamities cause a substantial
loss of GDP in south Asian countries every
year. Studies show 2 to 16 per cent of the
Gross Domestic Product of South Asian countries
is lost every year due to natural disasters.
They also show a dollar spent on mitigating
disasters saves five dollars to be spent
subsequently on relief and rehabilitation.
In such a scenario, countries in the Asia
region, which is considered one of the most
critical disaster hotspots in the globe.
Disaster losses must be prevented or mitigated
and kept at the minimum. Finding it is more
prudent and economical to invest in prevention,
mitigation and preparedness, there has been
a complete shift in the policy of these
countries for dealing with disasters. India
too has decided to mainstream the disaster
risk reduction into the process of development
and not treat it as just a matter of relief
and rehabilitation. This will be pursued
vigorously in the 11th Plan, now under formulation,
the sources said. Realising the importance
of disaster risk reduction, a Saarc disaster
management centre has been opened here recently
to serve member countries by providing policy
advice and facilitating capacity development
provision and exchange of information. As
part of the initiative, the centre will
collect, compile, document and disseminate
data, information, case studies, indigenous
knowledge and good practices relating to
disaster management particularly from the
member countries. It will collaborate with
other centres, particularly Saarc Meteorological
Research Centre, Saarc Coastal Zone Management
Centre and Saarc forestry sector to achieve
synergies in programmes and activities.
According to Union home minister Shivraj
Patil, "Recent advances in the field of
science and technology have opened up enormous
possibilities for developing an efficient
system of disaster risk reduction and management.
It is possible to prepare hazard, risk and
vulnerability maps at micro scale which
can make the task of risk assessment much
more accurate and fast." Mr Patil said it
is possible to track atmospheric depression
and predict weather and climatic conditions
at local levels with reasonable degree of
accuracy.

IITs
Retain Rank as World's Third Best Tech Varsities
|
| |
|
The
prestigious Indian Institutes of Technology
(IITs) have retained their number three
rank among the world's 100 best technology
universities, where the Indian Institutes
of Management (IIMs) also find a place.
The IITs, which were on number three slot
last year also, came next to MIT, Boston,
and California University, Berkeley, both
in the US, according to a survey conducted
by the Times Higher Education Supplement.
It placed Indian Institute of Managements
(IIMs) at number 68, sandwiched between
Hong Kong University and Eindhoven in the
Netherlands. The new technology survey showed
academic opinion about the top places for
science and engineering and puts IIT ahead
of Imperial College, London, which comes
in at number four. However, in last week's
rankings by THES on overall global excellence,
IIT had slid to number 57, seven places
lower than in 2005. According to a spokesman
of the Times Higher Education Supplement,
the latest technology table emerged following
an assessment of 3,703 academics, who had
been asked to rate universities in their
area of specialisation.

Air
India to Emerge as Asia's Airline
|
| |
|
Seventy
five years after the legendary father of
civil aviation J.R.D.Tata flew in a Puss
Moth from Karachi to Mumbai (October 15,
1932) the growth of Air India is synonymous
with the growth of civil aviation. The minister
for civil aviation, Mr Praful Patel, said,
"The platinum jubilee celebrations of Air
India's entry into 75 years of operation
is also a significant achievement for Indian
aviation as its growth can be rightly held
synonymous with Air India's development
and progress." The minister launched the
very elegant Platinum Jub-ilee celebrations
with a specially designed laser show beamed
on the landmark Air India building much
to the delight of the city's people that
were on the roads on a Sunday evening and
were lucky to see the show. A specially
designed emblem was also unveiled to mark
the 75 years. Mr Patel said "Despite increased
competition from other international players
in the country, I firmly believe in the
legacy of the Air India brand to tackle
all challenges and capitalise on opportunities."
Air India's chairman and managing director,
Mr V. Thulasidas recalled J.R.D. Tata's
historic flight and said "it's been a memorable
journey for Air India." He said since then
the airline has never looked back. "With
the acquisition of 68 new state-of-the-art
aircraft we aim to become the largest international
air carrier in Asia." Air India has expanded
its fleet by inducting 22 aircraft on dry
lease during the past three years, pending
delivery of the 68 new aircraft. The preceding
three years has seen phenomenal growth on
the European and US sectors. Air India was
nationalised on August 1, 1953 and bec-ame
the first all-jet airline in 1962. Today
it has grown into India's largest international
airline with a worldwide network of passenger
aircraft and cargo services which includes
Air India Express, India's only international
low cost carrier.

Acupuncture
can Cure 461 Diseases
|
| |
|
A
four-year research by a doctor with the
Chinese Acupuncture Clinic Research Center
in north China's Tianjin city has concluded
that acupuncture can cure 461 diseases.
Du Yuanhao, 43-year-old doctor, came to
this conclusion after finishing his study
on acupuncture functions. According to Du's
findings, acupuncture treatment is mainly
effective against diseases related to the
nervous system, the digestive system, the
genitourinary system, muscles, bones and
skins, such as stroke, diarrhoea, enteritis,
dementia and skin rashes. The points for
acupuncture are in flesh, and that is why
the treatment can be effective to diseases
in muscles and skins, Du said. "Besides,
points are rich in nerves. Thus it can also
cure diseases in the nervous system and
other systems whose functions are directly
controlled by nerves." Although acupuncture
is convenient and with fewer side effects
compared with other forms of medical treatment,
it couldn't cure every disease. As for these
461 diseases, Du noted, its effects are
different. The professor is now working
at classification for the 461 diseases.
"I am going to categorise them into three
levels - those that could be cured solely
by acupuncture, those to which acupuncture
is the major treatment and those with acupuncture
as assisting treatment. Acupuncture is part
of traditional Chinese medicine with a history
of over 2,000 years. It involves insertion
of fine metallic needles on the body to
relieve pain and cure diseases.

Jupiter
Tiny Spot Goes from White to Red
|
| |
|
Just
a little more than a ywear ago, the small
spot on Jupiter was a pale white; now it
matches the reddish hue of its bigger sibling,
the Great Red Spot, and boasts 400 mph winds,
according to new data from the Hubble Space
Telescope.
Top

Both spots are actually fierce storms
in Jupiter's atmosphere. While the red spot
- at three times the size of Earth - is
much more noticeable, strange things are
happening to the smaller spot.Scientists
aren't quite sure what's happening to the
smaller storm, nicknamed the Little Red
Spot or Red Spot Jr. but officially called
"Oval BA." It probably gained strength as
it shrunk slightly, the same way spinning
ice skaters go faster when they move their
arms closer, said
NASA
planetary scientist Amy Simon-Miller. Her
findings from the Hubble data were published
in the astronomical journal Icarus. As the
storm has grown stronger it's probably picked
up red material from lower in the Jupiter
atmosphere, most likely some form of sulfur
which turns red as part of a chemical reaction,
she said. The color change took astronomers
by surprise. And now they figure more surprises
are in store as the solar system's largest
planet goes into hiding from Earth's prying
eyes until January, moving behind the sun.
