First, gravity is a force that causes objects to attract one another. The simplest way to understand gravity is through Isaac Newton's law of universal gravitation. This law states that every particle in the universe attracts every other particle. The more massive an object is, the more strongly it attracts other objects. The closer objects are, the more strongly they attract each other. An enormous object, like the Earth, easily attracts objects that are close to it, like apples hanging from trees. Scientists haven't decided exactly what causes this attraction, but they believe it exists everywhere in the universe. Second, air is a fluid that behaves essentially the same way liquids do. Like liquids, air is made of microscopic particles that move in relation to one another. Air also moves like water does -- in fact, some aerodynamic tests take place underwater instead of in the air. The particles in gasses, like the ones that make up air, are simply farther apart and move faster than the particles in liquids.|New Mitsubishi Motors Corp.'s concept plug-in hybrid electric vehicle (PHEV) 'PX-MiEV' is displayed during the Tokyo Motor Show at Makuhari Messe in Chiba, Japan. Electric cars are picking up speed -- from compacts to sports and luxury options, they're touted as the next key to saving the environment. Experts anticipate difficulty convincing the majority of Americans that cleaner air is worth the perceived inconveniences of charging and range limitations. Assuming the reserved fuel is occasionally burned, plug-in hybrids aren't as clean, but if they manage to change perceptions, the trade-off might be worthwhile. There are a few factors to consider when evaluating how plug-in hybrid cars will impact the environment. Early adopters to EVs (full electrics and hybrids) are attracted to the environmental benefits but studies show that most drivers perceive the financial aspect to be the primary benefit. A J.D. Power survey of 4,000 respondents indicated that, while new car buyers might be drawn to hybrids (including plug-ins), the low cost-per-mile is the main draw; the environmental benefit is secondary.
Under their fur, giraffes have dark gray skin with no spots at all. But the fur has spots that can be round, oval or blobby, with sharp or smooth edges, and every shape and state of definition in between. They're variable, but the spots remain the same throughout the giraffe's lifetime. Researchers were able to confirm that spot attributes, like sharply defined edges, are passed from mom to baby. In this study, newborns that had larger, more irregular spots were more likely to survive the first few months of life. This new finding is an update of an old hypothesis. Dr. Anne Innis Dagg observed a small zoo population of giraffes and noted that the shape, number, area and color of their spots seemed to be passed down. The latest study used computer imaging. Analysis to compare 11 traits found in the spots of giraffes in the wild. The method could be used for studying other animals patterns too, like cheetah spots or zebra stripes. Dr. Anne Innis Dagg has been called "the Jane Goodall of giraffes" for her groundbreaking early work studying giraffes in the wild. With a $500 prize for biology and personal savings, she left for South Africa in 1955 and studied these leggy beasts, often observing them from her car.
All of these considerations -- and more -- have to be sorted through by each car's crew chief before every single race. We haven't even mentioned the physical changes the track undergoes during the race. If you want to know more, read the next page. Whenever you put 43 cars on a track, all putting out about 750 horsepower apiece and traveling about 150 (241.4 km/h) mph for 500 straight miles (807.6 km), a lot of energy is going to be transferred to the track. As a result, the track can't help but change a bit. While all NASCAR tracks change during a race, the most pronounced changes are seen on asphalt tracks. This is significant because 28 of the 31 official tracks used in NASCAR races are paved with asphalt; the other three are concrete. Technically, the asphalt tracks are concrete as well; the term concrete denotes a mixture of loose gravel (also called aggregate) held together with a binder, typically cement.
There are so many benefits an Indian student take from China's Universities and colleges. These things attract an Indian student. Quite different from Indian colleges. 1. First of all, direct admissions in top universities. 2. Every year thousands of Indian students came to China for studying in MBBS. 3. Educational level is good even better from India. 4. Medical facilities are far better than India. 5. A chance to learn and furnished your skills in MBBS to get allied with top medical hospitals. 6. Study standard is awesome at affordable prices. 7. International medical programs or medical studies are learned in the English language also. 8. After completing MBBS, no need to go India for medical practices. You can continue your medical practices at here in top medical hospitals. 9. No need to worry about the internship program. Because every university has their owned private hospital. So you can go there. Carry forward your internship program.
High precision physics at future colliders as the International Linear Collider (ILC) require unprecedented high precision in the determination of the energy of final state particles. The needed precision will be achieved thanks to the Particle Flow algorithms (PF) which require highly granular and hermetic calorimeters systems. The physical proof of concept of the PF was performed in the previous campaign of beam tests of physic prototypes within the CALICE collaboration. One of these prototypes was the physics prototype of the Silicon-Tungsten Electromagnetic Calorimeter (SiW-ECAL) for the ILC. In this document we present the latest news on R&D of the next generation prototype, the technological prototype with fully embedded very front-end (VFE) electronics, of the SiW-ECAL. Special emphasis is given to the presentation. 250 GeV - 1 TeV. ILC requires unprecedented precision in the energy determination of final states. These techniques rely on single particle separation in the full detector volume to choose the best information available to measure the energy of the final state objects (i.e. measuring the charged particles momentum at tracking devices better than in the calorimeters). Therefore, PF algorithms require highly granular and compact calorimeter systems featuring minimum dead material (high hermeticity).
