Q&A-3: "Does Caste Continbue to Haunt Urban India?"
Eyecatchers-124: "Towards Fuel Efficiency"
1. Drive your car at 40-50 kmph, optimum fuel-efficient speed to give you maximum mileage. You can save up to 20% of petrol against driving at 70 kmph. (I think it is applicable to two-wheelers also and if you are driving a moped like me, 30-40 kmph may be the optimum speed).
2. Clean your car’s air filter regularly – dust causes rapid erosion of engine components and increases fuel consumption.
3. Always ensure that you drive in correct gear for better fuel efficiency.
4. Car-pooling reduces the number of cars plying on the roads, thereby leading to decongestion of traffic and decreasing pollution. It simultaneously leads to lesser greenhouse gas emissions and cuts traveling costs. The system also tackles the problem of inadequate parking space. Car-pooling eases driving stress and helps broaden your social network, increasing productivity and boosting morale.
5. Switching off engines at red lights for over 15 seconds
6. Using the recommended grade of engine oil
7. Periodically checking tyre pressure
8. Regular maintenance of vehicles is imperative
Use these tips from PCRA to make your contribution towards saving fuel and do your bit to tackle climate change.
A mere 2% saving of petroleum products will translate into saving of Rs.10,000 crores per annum!

S&T Watch-38: "New Electric Hybrid Bicycle"
The system harnesses energy from braking when the bike goes downhill, and can add extra power equivalent to double the rider's pedal force for going uphill.
The bike can travel 1.8 times faster than conventional bicycles, thanks to the motor powering its front wheel - AFP.

Health News-9: "World AIDS Day"
From its inception until 2004, UNAIDS spearheaded the World AIDS Day campaign, choosing annual themes in consultation with other global health organizations. In 2005 this responsibility was turned over to World AIDS Campaign (WAC), who chose Stop AIDS: Keep the Promise as the main theme for World AIDS Day observances through 2010, with more specific sub-taglines chosen annually. This theme is not specific to World AIDS Day, but is used year-round in WAC's efforts to highlight HIV/AIDS awareness within the context of other major global events including the G8 Summit. World AIDS Campaign also conducts “in-country” campaigns throughout the world, like the Student Stop AIDS Campaign, an infection-awareness campaign targeting young people throughout the UK.
It is common to hold memorials to honor persons who have died from HIV/AIDS on this day. Government and health officials also observe, often with speeches or forums on the AIDS topics. Since 1995 the President of the United States has made an official proclamation on World AIDS Day. Governments of other nations have followed suit and issued similar announcements.

Eyecatchers-122: "Two Million Books/Articles/Images in Public Domain!"
In the meanwhile some info about the Europeana project.
Europeana is a search platform for a collection of European digital libraries with digitized paintings, books, films and archives. The project was initiated by the European Commission. The Library contains around two million digital items, all of them already in public domain.
I repeat for the sake of bloggers, all the 2 million items are in the PUBLIC DOMAIN, which means you can use, re-use, distribute, re-distribute, excerpt and probably modify also; of course, with ncessary credit/attribution. Sort of bonanza, what you think!
The project aims to have 10 million works by 2010, when Europeana is due to be fully operational.
Grateful thanks to The Hindu and Wikipedia, the free encyclopedia.
Open Access-6: "Open Access and the New Possibilities Offered by Digitization"
In the end, exactly as Origen has taught us, the changes in communication technologies shift our relations to documents and transform the meaning we ascribe to their existence. If this is true, then it is time to go back to fundamentals. Fundamentally, science is open knowledge and its energy flashes out of the shock of ideas. The end result of this fundamentally agonistic activity is a critical edition of sorts, always striving to reach perfection, yet never ended or ending. Seen from on high, science is little more than an endless concatenation of texts that correct or refute each other, topic by topic, argument by argument, fact by fact. One might say, however scandalous this might sound at present, that science is a kind of Wikipedia, but a Wikipedia where attribution is closely monitored and where participation depends on credentials. If this characterization of science succeeds in capturing some of its essence, it becomes legitimate to ask whether the researcher will still be an "author" of "articles" 30 years from now. The author form is a child of print, and authorship is different from attribution. Whether authorship will still be needed in a few decades is a question well worth asking.
The answer is far from certain....But a choice remains before us: will scientists and scholars finally recover the control over the tools needed for their great conversation, or will it increasingly be taken over by commercial interests? This is what open access is all about....
