Introduction to the theoretical basis of the information science
Initially I want to remind you that in my last post in BiblogTecarios: Can knowledge management? Introductory Post is a simple survey with which I analyze what they think, believe, know about the concept of knowledge management, so I would ask the favor of fill out it since then in my next post, I will be presenting the results . On this post, Jesus Tramullas share a comment saying that you can effectively manage and that is something that has been addressed over 10 years ago, think about it yet, “there is much material to cut on” and that definitely the concept is not clear.
overtake I want to be able to read the post on the subject, but at least from the area I’ve been working (knowledge management in the context of the Social Studies of Science, Technology and Innovation), it seems that the concept took a new look and even has been given certain connotations that come awakening new academic debates. For this occasion, I will not say much because I want to make an inquiry about a subject that is still in effect and that continues to generate multiple positions in this respect I speak specifically of the theoretical and epistemological of Library, Archival and Information Science.
The Improvement of Higher Education Technology
In the past decade, college graduates faced a market where industrial employment decreased. The growth in female labor force participation, which coincided with increased age groups entering the labor force, there was a sharp focus on labor demand and labor layoffs in manufacturing. In all sectors, increased productivity showed a reduction of person-hours used. The ability of the economy to provide high-paying jobs were lower supply and education requirements for entry into the study were older generally deteriorated occupational and wage level of workers in the industrial sector.
The orientation and structure of the existing education system, distanced itself from the education and training requirements of the new economic model that is catching on in Mexico, goes through a profound educational improvement. The introduction of new technologies in the industrial sector has questioned the careers and guidance, particularly in secondary education institutions, secondary and higher technical education system, which was introduced in the eighties asymmetrical development momentum of industrialization.
The modernization of higher education has led technological educational improvement covering both the approach to training students as the elements of this new scheme emphasizing education according to the characteristics of the new world order. The speed of technological advance also raises the need for an engineering dynamic and flexible, it can play a greater role in solving the problems related to assimilation, tecnology transfer and innovation.
Recent scientific discoveries
Discovery of water on Mars
The Phoenix mission was launched by NASA in August 2007 and landed on Mars on May 25, 2008, in order to analyze the water on Mars and potential habitability on Mars. The scientist Peter Smith of the University of Arizona’s Lunar and Planetary Laboratory was the one who was in charge of this mission.
The red planet’s surface is generally deserted without the presence of liquid water, however the mission Mars Odyssey Orbiter discovered that at its poles, beneath the surface dust had large amounts of ice. The purpose of Phoenix was digging the Martian soil, in areas where it believed it could be ice underneath. The Phoenix is supplied by solar energy and has a robotic arm which can excavate the surface and reach the ice. The robot, equipped with a laboratory can analyze samples and send the information to the team of scientists on Earth. A few weeks after his fall on the Red Planet of the water extracted solidified in order to analyze its composition, to study its geological history and study the viability of life on this planet.
The oldest hominid
In 1997 they found the fossil remains of the oldest bipedal hominid known to date, in Awash, Ethiopia. However, the paleontologist in charge of the excavations Yohannes Haile-Selassie, believed that these were remains of Ardipithecus ramidus (which inhabited our planet some 4.4 million years).
Robot reaches the NASA Mars
After a long journey of 8 months has landed on the surface of Mars Curiosity robot, sent by NASA for the exploration of its land. The vehicle was launched into space in November 2011 and has taken eight months to arrive. After a great expectation of all equipment in the Mars Science Laboratory (MSL) – Mars Science Laboratory – from NASA, the robot Curiosity could land on the Martian surface. The move was risky because it incorporated a crane to drive the robot to land a ton without suffering damage.
The team of the Mars Science Laboratory (MSL) and is monitoring all movements and sorting all the data obtained by Curiosity on Mars.
President Obama posted a message on his Twitter: “Tonight, on Mars, the United States of America made history. I want to congratulate and thank all the men and women of NASA who made this remarkable achievement a reality.”
Curiosity Mission
Envoy to Mars is one of the most modern astronauts robots created thus far. Is expected to remain for two years in exploring the planet Mars and sending information for analysis, particularly as related to the presence, in the present or the past, mycobacterial primitive life .
Onyx Solar will build the largest U.S. photovoltaic skylight
The Spanish company set up a large skylight PV in East Hanover (New Jersey). 2,457 meters square and will have an installed capacity of 295 kWp.
The Spanish company Onyx Solar will be responsible for constructing the largest photovoltaic skylight to be held in the United States. The project has been selected by Turner Construction, U.S. firm in charge of raising these facilities.
The skylight shall consist of 820 semi-transparent glass photovoltaic properties capable of generating clean, free energy from the sun, and have been tailored to the project.
As an architectural element, the skylight is known for its multiple functions, it not only generates energy but also allows the passage of natural light, thermally and acoustically insulate the building and offers an attractive design and adapted.
The robotic vehicle ‘Curiosity’ lands on Mars
The robotic vehicle ‘Curiosity’ has landed on the surface of Mars at 1.30 am on Monday (7.30 pm in mainland Spain), as reported by NASA through a statement.
The vehicle took off aboard an unmanned rocket Atlas 5 on 26 November, and during these nine months, has traveled about 60 million miles.
Over the next two years, the new NASA mission will consist of a geological expedition to a mysterious place called Gale Crater, located just south of the Martian Ecuador on Mount Sharp. Scientists believe the crater was formed approximately between 3,500 and 3,800 million years ago when Mars, the Earth and other planets of the solar system were bombarded by meteorites on a frequent basis.
Unknown history of Buran, the Soviet space plane
Unknown history of Buran, the Soviet space plane
Russian military consolidated the idea of developing a space plane, after U.S. President Richard Nixon authorized the project to develop the space shuttle (shuttle) in 1972.
In 1976, the Soviet high command again expressed concern about the public presentation of the first shuttle, a test vehicle called Enterprise, this time, the Russian military got approval to undertake a parallel program and make its own space shuttle.
On April 12, 1981, there was the first American shuttle flight, the famous Columbia, in a successful test mission in orbit. This, the Soviet military left more uneasy, thinking that the American shuttle would be used in military missions, a belief that was strengthened in 1983 with the launch of the Strategic Defense Initiative (SDI) or ” Star Wars “-driven President Ronald Reagan.
So, Moscow strategists faced the urgent need for a spacecraft with identical capabilities to those of the shuttle. In response, was enhanced program development and reusable manned space vehicles, strengthening rapidly, the precarious Soviet efforts in this area, undertaken since 1965 (project Spiral)
A powerful rocket is the first
Immediately, Soviet engineers focused on the development of a rocket far superior to those available in capacities since been transported to a space ship heavy, be a vector space completely safe and reusable. Another complexity was that the shuttle would be attached to the side of the rocket, this was a great challenge. While the United States used two solid-fuel rockets to assist take-off, and a large tank of liquid fuel to power the engines of the Shuttle. The Russians used only fuel and the Soviet shuttle would be transported into space as a burden by the rocket. Thus was conceived the vector in ERGY , 60 meters high, comprising a main body with 4 cryogenic engine RD-0120, and four auxiliary rocket Zenit-type, each with an RD-170 engine, one of the most powerful engines and reliable. In 1987 the Energy rocket made a successful maiden flight, putting into orbit a military satellite enormous weight of 80 tons.
Power Pwn, a hidden terminal networks to hack into a power strip
If one day we entered the office and see a strip of this type under the table may not surprise us. But if you look a little something that would attract attention, besides the fact that it uses American-style plug, why do you need other additional ports on the side?
This strip, conventional in appearance, hides a number of transmitters 3G, Bluetooth and WiFi allowing remotely make different safety tests to check whether a network is secure and detect certain vulnerabilities by applying a series of stress tests and exploits of all kinds.
Robot vacuum cleaner
iRobot Roomba 565 Pet has presented a version of its robot vacuum cleaner suitable for homes with pets. It is a tool that will end with the hair left by pets without being aware of it. Roomba 565 Pet has specific carpets to remove dirt and hair and anti-tangle technology to avoid getting stuck.
People who have pets like cats or dogs recognize that a clean home is much more difficult and requires ongoing maintenance effort. It is inevitable that animals are hair loss. For the soil is always clean would be behind them with a broom or vacuum cleaner in hand, in homes where children are also more important to maintain proper hygiene.
Next season: space (startram)
The project promises to bring charges Startram Earth orbit with an approximate cost of $ 40 per kilogram. Assuming that weigh about 80 pounds and want to carry 120 kg of luggage, you could go into space for less than 6,000 €.
It consists of a magnetic levitation train, similar to those used above ground, but moving along superconducting wires suspended in air by magnetic forces. Designed by one of the inventors of the trains used in countries like China and would travel into space in a sealed tube of about 130 miles long.
The project would cost about 60,000 million dollars and could be carrying loads (up to 300,000 tons per trip) to the space within 10 years and passengers in 20. Moreover, the existence of half as cheap space transportation would generate inexpensive solar power in space and exploit the minerals in the asteroids. The system would be capable of accelerating vehicles 30G, reaching a speed of about 8 kilometers per second. One of the creators of Startram, Professor James Powell states.” The resources of our own solar system are enormous.
