For†¯additional info, just keep reading – we also have some excellent suggestions for you. What Is a Coral Reef? When you write about coral reefs, you should have a clear understanding of what is a coral reef ecosystem, and what is a coral. We all saw corals on photos, videos or even live. But what exactly are corals? Are they plants or animals? Let's find out! Corals neither are plants, nor a quaint stone, but living marine polyps that have a unique limestone skeleton structure growing about 15 mm every year. Corals are the lower coelenterate multicellular creatures in the world's oceans. Imagine a solid lime cylinder, surrounded from the inside and outside by a soft tissue of cells. In its center is the "mouth" of the coral and then it turns into the abdominal cavity. The coral feeds on plankton, capturing small marine organisms with its tentacles around the mouth, which have mucus that paralyzes the prey. Corals in their structure are very different. Some corals have a solid skeleton (which is called madrepores), some don’t have it, and some have mixed type of skeleton, like tubular coral. There are both solitary and colonial corals, which together form a complete barrier, shore reefs or atolls. Old corals die, and new living corals grow on top of them.

Official NASA portrait of astronaut Dr. Judith A. Resnik. NASA   Education Judith (Judy) Resnik went to Firestone High School, graduating as valedictorian of her class. She actually had a place waiting for her at Juilliard School of Music in New York but elected instead to study mathematics at Carnegie Mellon University. While there, she began studying electrical engineering. She did her masters degree work at the University of Maryland. Eventually, she went on to get a Ph.D. in the subject in 1977. While pursuing her graduate studies, Resnik worked at RCA on missile and radar projects for the military. Her research into integrated circuitry caught NASAs attention and played a role in her acceptance as an astronaut. She also did research into biomedical engineering at the National Institutes of Health, with a particular interest in vision systems. During her graduate studies, Resnik also qualified as a professional aircraft pilot, ultimately piloting NASA T-38 Talon aircraft. During the years before her eventual acceptance at NASA, she worked in California, getting ready for the application and tryout process. NASA Career NASAs first class of female astronauts: Shannon W. Lucid, Margaret Rhea Seddon, Kathryn D. Sullivan, Judith A. Resnik, Anna L. Fisher, and Sally K. Ride.   NASA In 1978, Judy Resnik became a NASA astronaut at the age of 29. She was one of six women accepted into the program and went through its rigorous years of training. She often cited the actress Nichelle Nichols (from Star Trek) as an influence on her decision to join NASA. In her training, Resnik focused on all the systems astronauts were required to know, and paid particular attention to robotic arm operations, as well as the deployment of orbiting experiments and solar array systems. Her work on the ground focused on tethered satellite systems, spacecraft manual control systems, and software applications for the remote manipulator systems.   Astronaut Judith Resnik during egress training at NASA. NASA   Resniks first flight took place aboard the space shuttle Discovery. It was also the maiden voyage for the spacecraft. With that mission, she became the second American to fly, following the first woman, Sally Ride. Many viewers of the IMAX film The Dream is Alive first saw her as the astronaut with long, flowing hair, fast asleep on orbit during one of the scenes.  Ã‚   Astronaut Judith Resnik (left) and crewmates aboard space shuttle Discovery in 1984.   NASA Resniks second (and last flight) was aboard the space shuttle Challenger, which was to carry the first teacher to space, Christa McAuliffe. It broke up 73 seconds into launch on January 26, 1986. Had that mission been successful, she would have been one of the mission specialists, working on a variety of experiments. In her short 37-year lifespan, she logged 144 hours and 57 minutes on orbit, worked toward two degrees in science, and pursued both her work and her hobbies (cooking and car racing) with equal intensity.   Personal Life Judith Resnik was briefly married to engineer Michael Oldak. They had no children, and both were engineering students when they met. They divorced in 1975.   Memorial plaque at the Astrononaut Memorial wall in Florida.

Building the Boeing 787 Case Study Essay Example | Topics and Well Written Essays - 2500 words

Building the Boeing 787 Case Study - Essay Example It manufactures commercial aeroplanes, military jets, space shuttles and rockets. It has over the years produced a series of planes among them the latest project; the Boeing 787. This project was referred to as the 7E7 before being renamed the 787 in 2005. The plane has a similar size to the 767 with the overriding advantage over the former being its fuel consumption which is at 20% less. In addition to fuel efficiency, the 787 is credited with features like smooth nose shape, noise reducing chevrons and a four-panel windshield which are streamlined to reduce air resistance when airborne (Turner, 2010). This 787 project has not gone smoothly without operational hiccups; when the engineers came up with the first design, the plane said to have been overweight to the tune of 2,300kgs above the specified weight. This was however not all; there were 7 delays in the project process among them being an in flight fire on the Rolls Royce engine during testing. That not enough, just in the mon th of January 2012, the company reported numerous problems on some 787 fuselages. The effort and capital that was employed to come up with this latest machine is outrageous. Once the airline companies and other clients found the products offered by this company faulty, they claimed compensation which resulted in a dip in Boeing’s margins. Boeing’s corporate profile In terms of turnover, the company is among the largest in designing, assembly, selling and after-sales maintenance of aircrafts and other defence equipment. There are other companies within the European Union for instance the European Aeronautic Defence and Space Company (EADS) and French owned Dassault, who collectively share this global aircraft manufacturing business with Boeing. It is placed third, according to the latest estimations, in supply of defence systems and aerospace equipment with the biggest client being the American government. America continues to have interest in the management of the comp any because of the place it occupies in being part of its future ambitions in space exploration and general protection of the citizenry. The company, listed in the Dow Jones bourse, is America’s sixth largest exporter by product value. Good share prices at the listing helps it get more operational capital to finance its expansion strategies which is vital in an increasingly competitive market with new entrants like Embraer from Brazil. To add insult to injury, the year 2001 bombing of Twin Towers in New York dented the company’s revenue streams as the markets were down because of weak American economy. Such terrorist activities and general insecurity causes a fall in the number of airline passengers and increases fuel prices which are the two main problems associated with airline industry. Boeing global business model focuses on mass production of these plane components and defence equipment. It has a strong and well funded research and development department that look s into new technologies to tackle global communication problems. Its vitality as a producer of these important gadgets to the American government makes it look like a partner to the administration which funds some of its processes. In 2007, it partnered with NASA which is fully funded by the government to produce special parts of the Space Shuttle. By the year 2008, it topped the list of companies with the highest value
