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).
System to improve water purification
TecnoConverting, company water treatment sector, in collaboration with the CTM Technology Centre has developed a technology which can improve water treatment systems and water treatment, especially in the secondary settling stage.
The company said the technology called TecnoTec, using the numerical simulation by finite element method to calculate and validate the design of systems with lamellar settling.
“Through computational fluid dynamics calculation with commercial programs, we have determined the distribution of water flow and speed, the presence and location of turbulence and re-circulation zones, identifying areas where sedimentation will be based on the type flake and suspended particles, predicted in the lamellar seals, etc. With this strategy, we evaluate the efficiency of the preliminary design of settling these systems, “say the makers.
