Preliminary trials of anti-collision system successful: Mittal

Jammu: Preliminary field trials of Train Collision Avoidance System (TCAS) in South Central Railways have been successful, Chairman Railway Board Vinnay Mittal said on Monday.

"We are experimenting with TCAS in South Central Railways. Preliminary field trials in South Central Railways have been successful," he told reporters after reviewing work on under-construction railway infrastructure in Katra, the base camp of Mata Vaishno Devi Shrine.

Mittal said, "it is GPS based system...We are trying to spread the trials to a distance from 150 to 200 km and cover many more locomotives and establish its efficiency."

"We are also looking into protective warning system which is an European based system," he said, adding it is a cheaper technology.

He was replying to a volley of questions about the collision of trains and accidents and safety measures taken by the railways in this regard.

A safety device designed to prevent train accidents, TCAS is based on a combination of railway signalling data with radio communications, global position, radio frequency identification devices, software and logic.

Field trials were conducted last month in real time on a track near Tandur station. Two TCAS-equipped locomotives operated a series of test runs, simulating scenarios including head-on collisions, rear-end collisions, and SPAD (Signal Passed at Danger).

Decoding 'orphan crop' genomes could save millions of lives in Africa

Howard-Yana Shapiro, a scientist with the Mars confectionery company, will make the information free to boost harvests

The future wellbeing of millions of Africans may rest in the unlikely hands of a vegan hippy scientist working for a sweet company who plans to map and then give away the genetic data of 100 traditional crops.
Howard-Yana Shapiro, the agriculture director of the $36bn US confectionery corporation Mars, led a partnership that sequenced and then published in 2010 the complete genome of the cacao tree from which chocolate is derived. He plans to work with American and Chinese scientists to sequence and make publicly available the genetic makeup of a host of crops such as yam, finger millet, tef, groundnut, cassava and sweet potato.
Dubbed "orphan crops" because they have been ignored by scientists, seed companies and governments, they are staples for up to 250 million smallholder African farmers who depend on them for food security, nutrition and income. However, they are considered of little economic interest to large seed and chemical companies such as Monsanto, Bayer and Syngenta, which concentrate on global crops such as maize, rice and soya.
According to Shapiro, there is huge potential to develop more resilient and higher-yielding varieties of most orphan crops by combining traditional plant breeding methods with new biotech tools such as "genetic marking". This does not involve the altering or insertion of genes that takes place with controversial genetic modification.
"The genetic information will be put on the web and offered free to plant breeders, seed companies and farmers on condition it is not patented. A new African plant-breeding academy will also be set up in Nairobi, Kenya," he said."It's not charity. It's a gift. Its an improvement of African agriculture. These crops will never be worked on by the big five [seed] companies. They don't see them as competition."
Shapiro, a leading plant scientist who founded organic seed company Seeds of Change but sold it to Mars in 1997, now cuts an idiosyncratic figure in the corporate food world, sporting a long beard and listing motorcycles as a favourite pastime. But he said that the culture of the family-owned corporation had advantages. "It took less than a nanosecond to decide not to patent. Ownership was not an issue," he said.
Shapiro is angered by the stunting caused by malnutrition that affects 30% of African children. By improving the crops, he said, the African orphan crop consortium, which includes corporations such as Life Technologies and the conservation group WWF, could eradicate a "plague" that costs Africa $125bn a year. "We will start with genomics, go to analysis, then to plant breeders, then to the field, then the seed companies, and then to the farms," he said.
Open-access publication of the cacao genome in 2010 is now bearing fruit. The genes that determine resistance to fungal infections and yield have been found and a new generation of cacao trees is being grown which should eventually quadruple production. "We haven't changed a single gene. It's inheritability. It's all done with grafting."
But the "improved" seeds expected to come out of the $40m orphan programme could change Africa in unexpected ways. Nearly 80% of all seed used in Africa is selected, saved and exchanged by farmers without money changing hands. The result has been an immense diversity of crops suited to particular localities and cultures. The new, "improved" seeds of the orphan crops may increase yields or disease resistance but could be unaffordable and might oust traditional varieties. It is also possible that the genetic decoding could open the door to genetic modification.

Yam harvests could increase significantly as hardier varieties are developed.
"Anything that keeps the [genetic] information out of proprietary hands is a good thing. But it's important to maintain the traditional varieties that have not been 'improved' and to keep a non-monetised path for the farming economy," said Camilla Toulmin, director of the International Institute for Environment and Development in London. "It's important to recognize improvements in crops are not just about genetics. How plants are managed is equally important."Agricultural investment in Africa will be a key point at the G8 hunger summit in Northern Ireland next weekend. Governments and 45 of the largest agribusiness corporations are expected to unveil initiatives to boost African farming.
West and east African small farmers' groups have joined British charities to say that small-scale family farmers were being excluded from the talks even though they feed 80% of Africans. "It's very important that governments prioritise investment to support family farmers and their more ecological food production," said Patrick Mulvany, chair of the UK Food group.
"Technological advances in food production can be part of the solution to increase yields. But the world already grows enough food yet one in eight people go hungry every day. G8 leaders can begin to tackle the scandal of global hunger by closing the tax loopholes, improving land rights and increasing public investment in developing country agriculture," said Lucy Brinicombe, spokesperson for the If coalition of 200 groups which includes Oxfam and ActionAid.



Tata Power to add 200-250 MW of solar, wind energy

New camera sensor may do away with flash someday soon

Singapore : The camera flash may soon be a thing of the past. A newly developed imaging sensor promises to produce clear and sharp photos even in dim lighting.
 
The sensor made by researchers at Nanyang Technological University (NTU) in Singapore is 1,000 times more sensitive to light than imaging sensors in most modern cameras.
 
"We expect our innovation will have great impact not only on the consumer imaging industry, but also in satellite imaging and communication industries, as well as the mid-infrared applications," tech site Mashable quoted the sensor's inventor Wang Qijie as saying.
 
Wang is an assistant professor at NTU's School of Electrical and Electronic Engineering.
 
He said this is the first time that a broad-spectrum, high photosensitive sensor has been made using pure graphene.
 
Wang said manufacturers will not have problems switching to graphene, saying the camera industry need not change its manufacturing processes - all it has to do is switch the base materials for graphene.
 
If the industry adopts his design, he said we could soon see cheaper, lighter cameras with longer battery lives.
 
For its part, Mashable said the new sensor may have applications not only in point-and-shoot cameras, but also in surveillance and satellite cameras.
 
The new sensor uses "light-trapping" nanostructures that use graphene as a base. The nanostructures hold onto light-generated electron particles much longer than current sensors.
 
"We have shown that it is now possible to create cheap, sensitive and flexile sensors from graphene alone," Wang said.
 
Graphene
 
Graphene, a one atom-thick layer of the mineral graphite, is a strong carbon compound with a honeycomb structure.
 
The structure makes it "as flexible as rubber, more conductive than silicon and which resists heat better than a diamond," Mashable said.
 
With such properties, graphene has been touted as the building material of the future, winning Andre Geim and Konstantin Novoselov the Nobel Prize in physics in 2010 for their work with it.
 
Graphene's properties make for stronger electric signals, which can be processed into an image, compared to the complementary metal-oxide semiconductor used by present cameras.

Nicobar islands declared a world biosphere reserve by Unesco

LONDON: The highly threatened Nicobar islands of India - home to 1,800 animal species and some of the world's most endangered tribes, has now been designated as a world biosphere reserve.

The island is home to the indigenous Shompen people, semi-nomadic hunters living inland and the Nicobarese, who are coastal dwellers dependent on fishing and horticulture.

The Andaman and Nicobar Islands in the Bay of Bengal are an archipelago of approximately 527 islands, islets and rocks. This underwater mountain range manifests itself above water as a chain of emerald islands of exceptional beauty and conservational importance. The islands’ immense biological diversity is a result of ocean boundaries enclosing a wide range of ecosystems - open oceans, shallow seas and reefs, sandy beaches, rocky shores and sea caves, mangroves and wetlands, littoral forests, giant lowland evergreens and hill top forests on this 6000sq km land.
