Scientists at the European Space Agency (ESA) have announced that the ceramic miniaturized gas sensors have a new commercial application, and is not in space. These sensors are used to measure levels of oxygen in spacecraft reentry into the atmosphere. But now a group of experts in space technology has shown that smaller sensors can be used to strengthen control Aerobic exercise with the Bender ball to shape your figure of burning heaters, as well as improve the equipment that analyze the breath of human security and production of fuel cells.
The Institute of Space Systems (IRS) of the University of Stuttgart (Germany) began to develop gas sensors ceramic special fifteen years ago. These sensors are used to measure the distribution of oxygen in the plasma wind tunnel used to test heat shield materials for spacecraft re-entry into Earth's atmosphere in extreme conditions, according to scientists.
"The sensors that there were not suitable for space systems because they were great, quite heavy and consume a lot of thermal power," said Rainer Baumann, a researcher at the Technical University of Dresden (TU Dresden), Fitness Bender ball method muscles and sweat exercises which was part of the project to produce smaller sensors . "Therefore, we had to develop a new type of miniaturized sensor to measure the conditions of re-entry of spacecraft. The sensors had to be very small and capable of measuring the oxygen at high altitudes and during reentry."
Despite its traditional use in space-related activities, the technology transfer program Aerobic exercise with the Bender ball to shape your figure (TTPO) of ESA and MST, its partner in the technology transfer network, demonstrated in a series of presentations that the technology of sensors Gas may have other applications. This idea encouraged researchers from the IRS to further develop the sensor and promote their use and land space in the field of analysis of modern gas.
Mr. Baumann said: "It's very easy to find terrestrial applications for this miniature gas sensor. Reacts very quickly and is very useful in many cases where you need to measure environmental conditions on the ground." The researcher also mentioned the practical possibility of using the sensor for analyzing human breath. "With this sensor can measure oxygen, carbon dioxide and flow of human breath, and get the results right away," he said, adding that "this is impossible with conventional systems."
The miniature sensors can also be used to control the gases produced by heating systems industrial and domestic. "The sensor works well with gas fuels and can be used to optimize industrial boilers and heating systems for homes," said researcher at the TU. "This system can reduce the exhaust gases harmful to the environment and also to ensure that the heating system works best, can help reduce fuel consumption at between 10% and 15%."
From a safety perspective, the sensors can be used to trace leaks of hydrogen in industrial facilities, including those dedicated to the production of fuel cells. "Technology transfer is not a one-way direction," said Frank M. Salzgeber, director of the TTPO. "In the future we will witness other terrestrial technologies applicable to space."
On the other hand, the experts said they also miniaturized sensors are being used to measure the level of gases outside the International Space Station (ISS), specifically in the unit called FIPEX ( "Flux (Phi) Probe Experiment - Time Measurement of Atomic Oxygen resolved ").

Telefonica Will Increase by 0.7% on Average Its Tariffs Next Year
The next year, Telefonica will increase the price of so-called metropolitan, provincial, and international. According to Cope, the rise will be half of 0.7%.
Customers who have contracted services with broadband Internet will face an increase in their bill of 0.2 percent on average in 2009. Those who do not have ADSL or flat rate voice will suffer a rise of 1.3 per cent on your bill with the increase in the price of calls.
According to Telefonica, will not change the price of calls from fixed to mobile nor any of the products of broadband Internet: ADSL, waste, Trios and Imagenio.
The operator has begun to charge services that were once free
Telefonica announced that it would begin to charge 0.58 euros from the month of November by the Caller ID service. It is not the only measure taken by the operator to increase its revenue.
Since the Sept. 15, the period of bonus Call Technical Assistance Center (TAC) after the acquisition of an ADSL service was reduced 15 days before it was free for a month. Last month also began to collect the holder of changes in phone lines when they were previously free.

Blogeale, Microblogging of Bloggers and Blog Readers
Henry Brito maintains contact to present Blogeale, which it describes as the social network of bloggers and blog readers. This is a new microblogging service, which takes a few days running, and whose approach is aimed at allowing our fans access to the latest entries in our blogs through the publication of an extract from them in our timeline.
The operation is similar to other networks microblogging, where we have our network of supporters and people who follow us. In our timeline will have the status messages, which in this form the microposts the network, we deliver messages directly, and may reach up to 180 characters to use, combined with excerpts from the entries, both ours as to persons we continue, as well as notices of activities. We also have a timeline public a list of responses received, and a chronological timeline where only found.
When I talk about timeline, I mean a list whose messages are arranged in order of appearance over time.
When we access to an extract of an entry, we have a series of icons that allow us to access the full content of that entry without leaving Blogeale, translating the entradillas with a specific language, adding that entradillas as favorite valuing both positive and negative, as well as a permanent link.
Any message of state, both microposts as excerpts from our blogs, can be added as favourites. In addition, when adding a blog, which must belong to one of the categories available, it provides us with a line of code that will have to put in it for verification. Users can modify the visual appearance, and developers have an API to build other services in Blogeale Basten.
In short, uses the format microblogging as an aggregator of blogs, but in this case, bloggers and not add RSS links. Let's say it brings a different view to access the content published by bloggers, taking advantage of the latest trends on the Internet, offering a visual ergonomic environment for such activity.
