Childhood cancer survivors 4 times more prone to post-traumatic stress disorder

Washington, May 4 (ANI): Young adult survivors of childhood cancers are four times more likely to develop Post-Traumatic Stress Disorder (PTSD) than their control group siblings, revealed a study.

The Childhood Cancer Survivors Study focused on 6,542 childhood cancer survivors over 18 who were diagnosed with cancer between 1970 and 1986 and 368 of their siblings as a control group.

The study found that 589 survivors, or 9 percent, reported significant functional impairment and clinical distress as well as symptoms consistent with a full diagnosis of PTSD.

On the other hand, eight siblings, or 2 percent, reported impairment, distress and PTSD symptoms.

“Childhood cancer survivors, like others with PTSD, have been exposed to an event that made them feel very frightened or helpless or horrified. This study demonstrates that some of these survivors are suffering many years after successful treatment. Development of PTSD can be quite disabling for cancer survivors. This is treatable and not something they have to just live with,” said Dr. Margaret Stuber, a Jonsson Cancer Center researcher and first author of the study.

Affected survivors reported symptoms such as increased arousal, phobias, startling easily, being hyper vigilant, avoidance of reminders of their cancer diagnosis and treatment, being on edge and suffering extreme anxiety.

They also reported that the symptoms kept them from functioning normally.

Other studies have looked for PTSD in childhood cancer survivors while they”re still children or adolescents, but the percentage reporting symptoms is far less, about 3 percent, Stuber said.

There could be several reasons for the discrepancy—today”s treatment regimens employ less toxic treatments and rely far less on whole head radiation for brain tumours, causing far less trauma to the young patients.

In addition, the improved supportive care available today could lead to fewer physical and cognitive late effects from treatment.

The survivors in Stuber”s study often underwent far harsher treatment regimens commonly used in the 1970s and early 1980s, and within the group studied, those that underwent the more toxic and damaging therapies reported more cases of PTSD.

Another possible reason that more of the young adults reported PTSD symptoms is because they”re facing the stressful situations typical for people at that age – finding a job, getting married, starting a family.

That stress may exacerbate the PTSD, said Stuber.

And because many of the patients in the study underwent harsh therapies, they often suffer from significant late effects – infertility, cognitive impairment, stunted growth. This adds to stress levels as well.

Those that suffer from cognitive impairment may find it impossible to go to college or to land a good job that earns them an adequate income.

Treatment options such as therapy and medication are available to help the survivors manage their symptoms. But addressing the issue will not be simple, said Stuber.

The study is published in the May issue of the journal Pediatrics. (ANI)

Shoppers have a lot to learn from migrating geese

London, Apr 20 (ANI): Even the most effective shoppers can take a lesson or two from ducks and geese in hopping from one shop to another on a busy high street, say scientists.

A study of pedestrian behaviour in a busy high street has shown that shoppers are inefficient.

Unlike more competent species — such as ducks and geese — which form streamlined groups to increase their velocity, humans trundle along in a way that cuts their average speed between stores by about a fifth.

Our problem is that we fall into U or V-shaped formations so we can chat with our companions, but this slows both our progress and that of people coming the other way, according to the Franco-Swiss study.

We are clearly more concerned with chattering than arriving at our destination — however appealing it might seem, said the study.

The findings imply the need for wider pavements and sophisticated urban planning to enable us to keep moving in crowded shopping streets.

A team of scientists from Paul Sabatier University in Toulouse, southwest France, worked with academics from Zurich Polytechnic in Switzerland to analyse two groups of pedestrians—the first was filmed in a French square on a weekday, the second in a shopping street, also in France, on a Saturday.

When the density of the crowd increased, groups of two remained side by side, but in groups of three, the formation changed.

The person in the middle hung back, and those on each side moved inwards to form a V-shape.

In groups of four, the two people in the middle both hung back to make a U-shape. When five or more were walking, they broke into sub-groups.

Dr Guy Theraulaz, director of research at the Centre on Animal Cognition at the university, said the formation was designed to ease conversation and eye contact.

“However, the walking efficiency is considerably affected. The configuration makes it difficult to go forward, and forces people coming the other way to operate big avoidance manoeuvres,” Times Online quoted the study as saying.

Thus, the average speed of a group of four in a crowd is reduced to just 0.9 metres per second.

The group would get to the next shop more quickly by splitting up or copying migrating geese to form an inverse-V — with a leader at the front and followers fanning out behind, said Theraulaz.

“But the main thing for geese is speed. The main thing for humans is communication,” he added. (ANI)

Men and women respond differently when it comes to stress

Washington, March 24 (ANI): A new study on 20-to-64-year-olds has shown that age and gender play a major role in how people respond to stress.

The new research was led by scientists from the Universite de Montreal and the Montreal Heart Institute in collaboration with colleagues from the Université du Quebec a Montréal and McGill University.

“Our findings suggest that women who are more defensive are at increased cardiovascular risk, whereas low defensiveness appears to damage the health of older men,” said Bianca D”Antono, a professor at the Université de Montréal Department of Psychiatry and a Montreal Heart Institute researcher.

Defensiveness is a trait characterized by avoidance, denial or repression of information perceived as threatening.

In women, a strong defensive reaction to judgment from others or a threat to self-esteem will result in high blood pressure and heart rate. Contrarily, older men with low defensive reactions have a higher cardiovascular rates.

The study was conducted on 81 healthy working men and 118 women.

Dr. Jean-Claude Tardif a Université de Montréal professor and Montreal Heart Institute researcher said that the physiological response to stress in women and older men is linked to this desire of maintaining self-esteem and securing social bonds.

“The sense of belonging is a basic human need. Our findings suggest that socialization is innate and that belonging to a group contributed to the survival of our ancestors. Today, it is possible that most people view social exclusion as a threat to their existence. A strong defensive reaction is useful to maintain one”s self-esteem faced with this potential threat,” said D”Antono.

As part of the study, participants completed four tasks of varying stress levels. The first task involved reading a neutral text on Antarctica”s geography before a person of the same sex.

The second and third tasks involved role-playing in which participants followed a script where they were sometimes agreeable and sometimes aggressive. The final task involved a non-scripted debate on abortion.

Heart rate and blood pressure were measured during each of these tasks as was the level of cortisol in saliva. Results showed that women and older men had elevated cardiovascular, autonomic and endocrine responses to stress – all potentially damaging to their health.

However, the researchers warned that more studies are needed to evaluate the long-term effects of defensiveness and its association to stress response patterns in disease development.

European company develops mobile robots that are autonomous and multi-tasking

Madrid (Spain), September 19 (ANI): An European company has developed innovative robots which are mobile, multifunctional, collaborative, autonomous and polyvalent, suitable for a wide range of work from street cleaning and rubbish collection to accompanying elderly people.

According to a report carried out in www.basqueresearch.com, this new generation of robots have been developed by TECNALIA Technological Corporation, and are a part of the European DUSTBOT research project under the remit of the VI European Framework Programme and in which TECNALIA is participating.

These latest generation robots are suitable for the monitoring of large spaces (open and closed), as guides for persons in large shopping areas (indicating to them where a particular shop or product is within a shopping centre), for accompanying elderly people or those with certain disabilities (both at home and outside), thanks to their functions of orientation, navigation, communications with others or tele-assistance centres.

They can also be used as guides in teaching spaces (museums, visitor centres), and for transport, storage and transport and goods deliveries, besides the cleaning of both open and closed surfaces, which have either difficult or easy access.

DUSTBOT has collaborative, multifunctional and autonomous robots that are capable of operating in partially destructured environments/situations based on information provided by a map.

The robots can also facilitate working in large areas, stations, airports and other types of public buildings, without being any obstacle for the activity of these places, given its reduced size, and without being a danger for members of the public, thanks to the novel system for the detection and avoidance of obstacles.

The rail station of the Euskotren company in the Bilbao neighbourhood of Atxuri in Spain was chosen for the public presentation of these devices.

The demonstration of two robot models was undertaken: the DustCart and the DustClean.

The DustCart robot, measuring 1.45 metres high and 70 Kg in weight, has a humanoid form and is designed to interact with the user and for the collection of low demand waste.

The DustClean robot, in the form of a small vehicle and measuring 96 cm high and 250 Kg in weight, cleans streets of dirt and dust. Moreover, both control the quality of air in real time.

“These robots are the solution for cleaning areas of difficult access and for the collection of rubbish at the very front door of, above all, persons who have mobility problems when moving the rubbish to the communal waste containers,” said Inaki Inzunza, Director of the Business Unit at the Tecnalia Technological Corporation.

First round of Indo-Swiss talks on black money to be held in December

New Delhi, Aug. 31 (ANI): The first round of consultations between New Delhi and the Swiss Government on tracing the black money deposited in tax havens in that country will be held in December.

However, there is no guarantee of prosecution of offenders on the basis of information secured from them.

According to Finance Ministry sources, Indian officials will have their first round of discussions with officials of Swiss government to evolve a legal system that will enable India to trace black money.

They said that such a system could be evolved through a Double Taxation Avoidance Treaty (DTAT) with Switzerland on the model of the agreements reached with countries of the Organisation of Economic Cooperation and Development (OECD).

Although, the DTAT could lead to information being secured from Switzerland in specific cases (in which individuals would have violated laws in India), but it cannot guarantee that such persons could also be prosecuted for that offence, they pointed out.

In April, Germany gave information in a case where an individual had violated tax laws and on the information given by the German government tax due from him was also collected.

But Germany gave the information on the specific condition that no prosecution would be launched against the individual and the government had to comply with that condition

Getting information from the Swiss banks was not an easy task, and Indian government will have to become eligible to ask for such information under a proper bilateral treaty.

Recently, the US government successfully tracked some cases of American citizens stashing away their money there. The US could even prosecute them. (ANI)

Boeing set to test unmanned aircraft in Australia

Brisbane, July 12 (ANI): Australian scientists and US aviation giant Boeing are set to test unmanned aircrafts, which would share airspace with piloted passenger planes without causing any collision.

In a non-descript shed in suburban South Park in Seattle, a team of young Boeing engineers are overseeing an experiment that provides a startling glimpse into the future.

Their 30-metre by 15 metre by five-metre-high unmanned aerial vehicle (UAV) “swarming” laboratory looks like a small indoor cricket shed with model rotor aircraft parked on the concrete floor.

Suddenly the UAVs are airborne and swarming around the shed, their pre-determined tracks, altitudes and collision avoidance mechanisms already programmed in using advanced algorithms that could ultimately spell the end of piloted aircraft, The Courier-Mail reports.

The aim of this cutting edge science is to build the mathematical models that will allow uninhabited aircraft to fly safely in controlled airspace.

Boeing’s new Australian research chief Bill Lyons talks about the aim behind the experiment: “To allow (unmanned) systems to operate at least as well as human piloted systems.”

The algorithms developed in the swarm lab will soon be put to the test in the skies above Kingaroy in southern Queensland in the world’s first ever trial of unmanned aircraft inside controlled airspace.

Airspace authorities in both the US and Australia, highly wary of having pilotless drones in potential conflict with airliners carrying hundreds of passengers, will require 100 per cent guarantees before they will allow the two to mix.

Senior Boeing engineer John Vian said the major challenge for unmanned aircraft operating in controlled air space is safety.

“We don’t know how these systems will develop. For these systems to be viable they have to be reliable and totally autonomous. We develop the technology, how it is applied is up the customer,” Dr. Vian said. (ANI)

Few people altered their behaviour in early stages of swine flu outbreak

London, July 7 (ANI): Perceptions of the swine flu outbreak led only few people to alter their behaviour, suggests a study.

Scientists at Institute of Psychiatry King’s College London and the Health Protection Agency carried out the research to assess public perceptions, anxiety, and behaviour change in relation to the outbreak.

Partakers were quizzed about their recent behaviour related to avoidance of places or activities.

The researchers found little behaviour change among members of the public England Scotland and Wales in the wake of intense media coverage and a major government advertising campaign.

Only two per cent of the participants reported high anxiety.

Most people, 72 per cent, reported no changes in the frequency of their hand washing, while 83 per cent said that they had not increased the amount that they cleaned or disinfected things.

Less than five per cent said that they had stayed away from people or places as a result of the outbreak.

The study has been published on the online edition of the British Medical Journal. (ANI)

Like humans, birds too avoid inbreeding

Washington, June 30 (ANI): Scientists have found that a strictly monogamous species of bird has the ability to choose partners with a different genetic profile.

The researchers, led by Richard Wagner from the Konrad Lorenz Institute for Ethology of the Austrian Academy of Sciences, said avoidance of inbreeding is evident among humans, and has been demonstrated in some shorebirds, mice and sand lizards. Now the black-legged kittiwake bird has been added to that list.

The scientists said they tracked 10 genetic markers to investigate whether kittiwakes avoid inbreeding by pairing with genetically distant mates, and whether inbreeding reduces the number of chicks they raised.

They found most pairs avoid inbreeding more often than expected by chance, suggesting kittiwakes can somehow tell who their relatives are in a large anonymous population.

The researchers said their study provides the first evidence of inbreeding avoidance in a strictly monogamous species, in which both parents contribute to rearing offspring.

Wagner conducted the study in collaboration with Etienne Danchin from Paul Sabatier University in Toulouse, France, as well as researchers from the Pierre and Marie Curie University in Parks, the Alaska Science Center and the University of Bern.

The study appears in the journal BMC Evolutionary Biology. (ANI)

How genetics influences mate selection among humans

Washington, May 25 (ANI): Shedding new light on how humans choose their partners, a Brazilian scientist has revealed that people have an inherent tendency to get attracted towards genetically opposite individuals.

Professor Maria da Graca Bicalho, head of the Immunogenetics and Histocompatibility Laboratory at the University of Parana, has said that people with diverse major histocompatibility complexes (MHCs) were more likely to choose each other as mates than those whose MHCs were similar.

And she said that this tendency was likely to be an evolutionary strategy to ensure healthy reproduction.

Previous studies have already shown females’ preference for MHC dissimilar mates in many vertebrate species, including humans, and it is also known that MHC influences mating selection by preferences for particular body odours.

In the current study, the researchers decided to investigate mate selection in the Brazilian population, while trying to uncover the biological significance of MHC diversity.

They studied MHC data from 90 married couples, and compared them with 152 randomly generated control couples.

They also counted the number of MHC dissimilarities among those who were real couples, and compared them with those in the randomly-generated ‘virtual couples’.

“If MHC genes did not influence mate selection, we would have expected to see similar results from both sets of couples. But we found that the real partners had significantly more MHC dissimilarities than we could have expected to find simply by chance,” said Bicalho.

Within MHC-dissimilar couples the partners will be genetically different, and such a pattern of mate choice decreases the danger of endogamy (mating among relatives) and increases the genetic variability of offspring.

It’s known that genetic variability is an advantage for offspring,and scientists said that the MHC effect could be an evolutionary strategy underlying incest avoidance in humans and also improving the efficiency of the immune system.

“Although it may be tempting to think that humans choose their partners because of their similarities. Our research has shown clearly that it is differences that make for successful reproduction, and that the subconscious drive to have healthy children is important when choosing a mate,” said Bicalho.

The scientists believe that the findings will help understanding of conception, fertility and gestational failures.

Bicalho will present the findings at the annual conference of the European Society of Human Genetics. (ANI)

Cutaneous application of nanoparticles may help treat erectile dysfunction

Washington, Apr 27 (ANI): New York scientists have found that cutaneous application of nanoparticles, could offer a new means of delivering drugs to treat erectile dysfunction (ED).

The findings have revealed that topical treatments for ED could provide localized therapeutic results with the benefit of lower dosage and the avoidance of adverse side effects due to systemic absorption.

For the study, the researchers investigated a novel hybrid hydrogel/glass nanoparticle platform.

They developed nanoparticles capable of sustained release of therapeutic levels of nitric oxide (NO), which aids in erection biology and relaxes smooth muscle cells in the penis.

They then applied these nanoparticles to the skin of the penis of seven rats, and measured erectile response by intracorporal pressure/blood pressure (ICP/BP) ratio.

It was found that out of the seven animals treated with NO releasing nanoparticles, five experienced positive effects on the ICP/BC, resulting in a visible erection.

The average time for an erectile response was found to be approximately 65 minutes.

“This is a very interesting concept which has potential to impact treatment of many conditions including erectile dysfunction if it can be translated from the animal lab to clinical practice. It remains to be seen whether the effect of the nanoparticle technology is a local or a systemic effect, ” said Ira D. Sharlip, MD, an AUA spokesman.

The study was presented at the 104th Annual Scientific Meeting of the American Urological Association (AUA). (ANI)

Mutations that hide HIV from immune system weaken its ability to replicate

Washington, Apr 13 (ANI): Scientists at University of Oxford have found that mutations that hide HIV from immune system weaken the virus’ ability to replicate.

According to them, when HIV infects a cell, a complex of human immune proteins called HLA (short for human leukocyte antigen) alert killer T cells by displaying bits of the virus on the surface of the cell, in response to which the T-cells trigger immune attack.

They suggest that individuals who have certain types of HLA proteins control infection better than others.

For instance, in people with HLA-B*5703, the virus multiplies less than in people with some other HLA variants likely because killer T cells in these individuals are quick to attack infected cells. However, HIV is tricky.

To get around HLA-B*5703, the virus mutates three amino acids that T cells need to recognize the infected cells, causing the killers to pass by the infected cell unnoticed.

Thus by mutating, the virus becomes invisible to the immune system.

In the new study, lead researcher Hayley Crawford showed that the triple mutant replicated 20 times slower than normal in cell culture.

During the study, the researchers examined Zambian couples in which one HLA-B*5703-expressing person infected with triple-mutant virus passed the infection to a partner who either did or didn’t have the same HLA variant.

When transmitted to a person without HLAB*5703, the virus changed its mutated amino acids back to their original sequence because the benefit of avoiding killer T cells no longer outweighed the cost of reduced replication.

However, when transmitted to another HLA-B*5703-expressing person, the triple-mutated virus came out on top despite its reduced replication. In these individuals, the avoidance of killer T cells allowed the infection to rapidly proceed to clinical illness.

The study has been published in Journal of Experimental Medicine. (ANI)

Environmental tobacco smoke exposure worsens asthma in kids

Washington, Apr 8 (ANI): Exposure to environmental tobacco smoke (ETS) can worsen asthmatic symptoms in kids, according to a new study.

During the study, research team from University of Alabama followed 240 children with asthma who were either receiving usual care or supervised asthma therapy.

The kids were given 20 minutes of asthma education that incorporated discussion on the avoidance of asthma triggers, including ETS.

The researchers revealed that kids whose ETS exposure decreased reported fewer hospitalizations and ED visits.

Moreover, these children were 48 percent less likely to experience an episode of poor asthma control.

The study is published in journal Chest. (ANI)

US military to boost satellite monitoring programme to avoid space smash-up

London, April 1 (ANI): The US military is planning to boost the number of satellites it routinely monitors for the risk of a smash-up with orbiting debris, like the recent collision between a US communications satellite and a defunct Russian probe.

The US Air Force has catalogued more than 19,000 pieces of space debris larger than 10 centimetres across, General Robert Kehler, Commander of Air Force Space Command, told New Scientist.

But, despite the extensive catalogue, the military does not have the ability to calculate the risk this space junk poses to every operational satellite.

“We keep that catalogue up to date, but we do not watch everything for collision purposes all the time,” Kehler said.

“We’re limited by computing and we’re limited by analytical wherewithal, both of which we are now going to increase in the near-term so that we can expand the population of satellites that we can perform routine collision avoidance assessments on,” he added.

The exact number of satellites the Air Force will aim to routinely screen for the risk of collision is unclear.

“We want to stay away from numbers and specifics right now,” Andy Roake, a spokesperson for Air Force Space Command, told New Scientist.

But, another official has put the target at 800 maneuverable satellites by October 1.

There are no details yet on how the effort would be funded or how much it might cost, according to an Air Force official.

That would put the Air Force close to a complete survey of the risk to space probes.

Some 900 operational satellites currently orbit the Earth, according to data compiled by the Union of Concerned Scientists.

“It’s absolutely a step in the right direction,” said Brian Weeden, a technical consultant for the Secure World Foundation and a former orbital analyst at the US Strategic Command’s Joint Space Operations Center.

“Boosting the number of satellites that are routinely watched may reduce the chance of collisions, but only if satellite operators are notified and given the information they need to determine whether to move the satellite,” he added. (ANI)

Low to moderate drinking, socialization good for your heart

Washington, Mar 20 (ANI): Low-to-moderate drinking and socialization is beneficial for cardiovascular heath, according to a new study.

A Japanese examination of the effects of social support on the relationship between drinking and cardiovascular disease has found that the health benefits of light-to-moderate drinking are more pronounced in men with greater social support.

Hiroyasu Iso, a professor of public health at Osaka University and corresponding author for the study, and his colleagues examined 19,356 men 40 to 69 years of age who were enrolled in the Japan Public Health Center-based Prospective Study.

Their alcohol consumption was classified into seven categories: ever, past, occasional, 1-149, 150-299, 300-449, or 450 grams/week. Measures used were alcohol consumption, risk of cardiovascular disease, and social support.

“We found the reduced risks of total stroke, ischemic stroke, and total cardiovascular disease associated with light-to-moderate drinking were more pronounced in men with high social support, probably due to avoidance of unhealthy behaviours and enhancement of stress buffering,” said Iso.

“In our study, compared with light-to-moderate drinkers with high social support, those with low social support had more unhealthy lifestyles such as physical inactivity, no job and fewer opportunities for medical checkups,” Iso added.

Results will be published in the June issue of Alcoholism: Clinical and Experimental Research and are currently available at Early View. (ANI)

Female birds ‘jam’ their partners’ flirtatious tunes

Washington, Mar 13 (ANI): Female antbirds sing over the songs of their male partners in a bid to prevent their flirtatious messages from reaching single female birds, a new study has found.

The study also found that males respond to that interruption by singing a different tune.

According to researchers, the findings offer the first evidence that such ‘signal jamming’ and ‘jamming avoidance’ occur between mates.

“In human terms, signal jamming is most commonly associated with attempts to scramble information in radio, radar, or cell phone signals,” said Joseph Tobias of the University of Oxford.

“The females in our study try to do a similar thing with the songs of their partner, but the overall situation is more analogous to a wife continually interrupting her husband to stop him from flirting with a single woman,” he added.

In a series of playback experiments, the researchers found that resident pairs of antbirds sing coordinated duets when responding to rival pairs. But under other circumstances, cooperation breaks down, leading to more complex songs.

Specifically, they report that females respond to unpaired sexual rivals by jamming the signals of their own mates, who in turn adjust their signals to avoid the interference.

Tobias said the females’ attempts to jam their partners’ songs are presumably intended to make the males less attractive, or to make it clear that they are ‘taken.’

He added that the results in antbirds may have broad implications for understanding how communal signals have developed over evolutionary time in many animals, and perhaps even in humans.

First, Tobias said, the findings reveal that group signals such as duets and choruses represent a subtle blend of cooperation and conflict. The balance between those two forces depends on the context.

Their study also suggests that if there is some conflict in the system, then multiple singers can combine to produce rhythmic, precisely coordinated, and increasingly complex songs simply by avoiding overlap.

“Most evidence points to vocalizations in early humans having a function in both mate attraction and resource defense, so it seems plausible that ‘signal jamming’ and especially ‘jamming avoidance’ played a role in our evolutionary history. If so, our results may help to explain the first steps towards complex, coordinated group signals in humans, which themselves are the likely forerunners to modern music,” Tobias said.

The study has been published online on March 12th in Current Biology, a Cell Press publication. (ANI)

Raccoon captured on White House grounds

Washington, Feb.26 (ANI): A raccoon has been captured on the grounds of the White House after weeks of stealthy avoidance.

The Washington Post quoted National Park Service, officials as saying that keeping with the interests of national security and animal civil rights, President Obama’s staff released few details of what was described as a “live capture,” in which the raccoon was caught and whisked away to an “undisclosed location.”

Deputy White House Press Secretary Bill Burton said it was “unclear” when the capture took place.

He did say that efforts to lure the animal into a cage using apples, cat food and peanut butter failed. Instead, the White House shifted to salmon for bait. It worked.

Burton could not identify whether the captured raccoon was the large one that had been spotted on the grounds recently, or one of the several medium-sized ones also roaming about.

He did say the raccoon was not harmed, and was released alive.

The Washington Post broke the news of the raccoon hunt earlier this month. Days later, White House press secretary Robert Gibbs said no progress had been made. (ANI)

Delhi National Load Despatch Centre to facilitate exchange of power

New Delhi, Feb 25 (ANI): Union Minister of Power Sushilkumar Shinde today dedicated the National Load Despatch Centre (NLDC) of POWERGRID to the nation here in the presence of Delhi Chief Minister Sheila Dikshit.

Speaking on the occasion, Shinde said that the NLDC would facilitate optimal exchange of power between regions.

” The NLDC in place the grid security at the national level will be considerably improved as it will provide real time information at one centralized location,” he added.

Congratulating the POWERGRID for creating the facility, the Minister said that the PSU today stands tall as one of the largest transmission utility in the world and is well known for its operational excellence and timely execution of transmission projects. He also complimented the POWERGRID team for its commendable achievement of avoiding any major grid disturbance in the country for the last six years.

In her address, Dikshit said that though the NLDC is located in Delhi, as a monitoring and supervising body, it would play a crucial role to ensure smooth and uninterrupted electricity through out the country. She said that it would facilitate avoidance of cascade trippings and maximization of inter-regional energy transfers.

The NLDC is linked with the 5 RLDCs, which in turn are connected to 31 State Load Despatch Centres (SLDCs). The NLDC at Delhi is also having a “back up” facility at ERLDC, Kolkata to take care of any eventualities. Set up at a cost of Rs.45.0 Crores, the NLDC and RLDCs have been provided with state-of-art technology.

The NLDC will be the apex body for ensuring integrated operation of the National Grid and power system in the country. The NLDC will facilitate optimum scheduling and despatch of electricity across Regional boundaries thus ensuring equitable utilization of surplus power countrywide while ensuring economy, efficiency, stability and security of the National Grid.

Establishment of National Grid by POWERGRID is facilitating exchange of surplus power from one part of the country to another thus catering to the demand in deficit states. POWERGRID plans to enhance the capacity of National Grid from 18,700MW to more than 37,000 MW by the end of 11th Plan through strengthening of Regional Grids by building more inter-regional links.

Over a period of 17 years, POWERGRID, a Navratna PSE, has emerged as one of the largest and best managed Transmission Utilities in the world and is playing a strategic role in Indian Power Sector. At present, POWERGRID is operating around 69,500 ckt. kms. of transmission lines and 117 Substations with a transformation capacity of 77,200 MVA. (ANI)

Disabled, ethnic minorities more susceptible to terrorism fears

Washington, January 22 (ANI): People who either suffer from some disability or belong to ethnic minorities, such as African Americans and Latinos, are more susceptible to terrorism-related fears than others, according to a new study.

University of California-Los Angeles (UCLA) researchers have found that such people make more behavioural changes based on terrorism-related fears, such as avoiding certain activities, than others.

Revealing their findings in the American Journal of Public Health, the researchers say that these groups also tend to overestimate the threat of terrorism, perceiving the risk as high even when the U.S. Homeland Security Advisory System’s (HSAS) colour-coded alert system rates it lower.

“Just like natural disasters have been shown to affect certain groups of people more than others, we’re now seeing evidence that terrorism fears are having a disproportionate effect on some of our most vulnerable groups,” said leady study author David P. Eisenman, assistant professor of medicine in the division of general internal medicine and health services research at the David Geffen School of Medicine at UCLA.

“It’s important for the public to know this because it shows that terrorism’s intention to induce fear and change does work – on the most vulnerable. Terrorism affects these groups even when there has not been an event in a long time.

“It also shows,” he added, “that the HSAS color-coding is misjudged by citizens, and the same persons who have the most fear and avoid activities are also misjudging it,” he added.

The researchers came up with these findings after conducting random-digit dial surveys conducted in six languages in Los Angeles County between October 2004 and January 2005.

During the study, the respondents were asked the colour of the country’s alert level at the time, how often they worried about terrorist attacks, and how often they avoided activities because of those fears.

The researchers observed that the mentally ill, the disabled, African Americans, Latinos, Chinese Americans, Korean Americans and non-U.S. citizens were more likely to think that the HSAS alert level was higher than it was, and to worry more and change their behaviour due to those fears.

Eisenman said that the study’s findings went on to suggest that the structure of the HSAS alerts needed to be re-evaluated – in part to ensure that terrorism alerts better reach vulnerable populations.

He further said that vulnerable groups also needed assistance to help reduce their fears and avoidance, so as to ensure that structures could be safely evacuated in the event of a terrorist act, and could help reduce some of the fears among the physically disabled.

“Terrorism-related fears and avoidant behavior can be considered part of the ‘disaster burden’ – the amount of adverse health effects ranging from loss of well-being or security to injury, illness or death caused by a disaster associated with terrorism and national terrorism policies. The disaster burden associated with terrorism and consequent policies may fall disproportionately on the vulnerable groups we studied,” the researchers conclude. (ANI)

The researchers observed that the mentally ill, the disabled, African Americans, Latinos, Chinese Americans, Korean Americans and non-U.S. citizens were more likely to think that the HSAS alert level was higher than it was, and to worry more and change their behaviour due to those fears.

Eisenman said that the study’s findings went on to suggest that the structure of the HSAS alerts needed to be re-evaluated – in part to ensure that terrorism alerts better reach vulnerable populations.

He further said that vulnerable groups also needed assistance to help reduce their fears and avoidance, so as to ensure that structures could be safely evacuated in the event of a terrorist act, and could help reduce some of the fears among the physically disabled.

“Terrorism-related fears and avoidant behavior can be considered part of the ‘disaster burden’ – the amount of adverse health effects ranging from loss of well-being or security to injury, illness or death caused by a disaster associated with terrorism and national terrorism policies. The disaster burden associated with terrorism and consequent policies may fall disproportionately on the vulnerable groups we studied,” the researchers conclude. (ANI)
