Using robotics developed by the space program‚ scientists constructed a mechanical exoskeleton that allows paraplegics to walk (right). These people have spent their lives without being able to walk due to paralysis from the waist down‚ and thanks to NASA they can now! “Overcoming the challenges of working in space has led to many technological

The Introduction As the entertainment industry continues to grow‚ many interesting and exceptional developments are being made to further the desire to produce fluid‚ life like‚ realistic animations. As a result of the increases in computational technology the quest to develop these techniques has accelerated within the past 10 to 15 years. Perhaps the newest realization has been the development of a process called motion capture. Motion capture has been around since the late 1970s‚ where it

created a very innovative new chair that was designed for people who constantly use office chairs‚ like business executives and other office workers. It wasn’t leather or big and black like most executive chairs‚ but small‚ wrapped with mesh over an exoskeleton‚ and with a new age look.

Insects are the most successful animal group. They are extremely diverse and abundant. They are present in the sea‚ in freshwater‚ on land and in the air. They occupy every ecological niche. Arthropods are not only extremely diverse but are also numerous as individuals. There are approximately 200 million insects for every human being on the Earth.(1) They have a huge impact on humans and our activities. They are pests of both food and animals‚ and are responsible for disease transmission. They also

Summary of Carbohydrates: Monosaccharides‚ Disaccharides‚ Polysaccharides Carbohydrates are molecules that are synthesized from carbon‚ oxygen‚ and hydrogen atoms. Some types of carbohydrates consist of a single unit consisting of a few atoms‚ while other carbohydrates consists of thousands of units linked together through chemical bonds. Glucose‚ maltose‚ and glycogen are three carbohydrates that are similar‚ but structurally different. Carbohydrates have the general molecular formula CH2O. Starch

The Burgess Shale Jared Yeargan EES 112 02-32318-2123 May 9th Spring 2012 As scientists seeking clues to the Earth’s and Mankind’s past; expeditions spanning the globe are often launched in search of fossils. Soft-shelled fossils are extremely rare due to their inherent fragility and rarity of necessary conditions to preserve such specimens. The Burgess Shale formation located in British Columbia contains some of the best-preserved and most abundant collections of soft-shelled fossils

INVESTIGATING THE ECOLOGICAL NICHE OF THE CRAB USING A FAIR TEST INTRODUCTION: The ecological niche of the crab Hemigrapsus edwardsi. The crab is a member of the Crustacea phylum and is in the family Grapsidae. This crab species is found only in New Zealand on rocky shores. The rocky shore‚ where the crabs studied in this investigation were found is quite exposed. There is a large rock platform that provides small crevices and small rocks which help to protect them from wave action and predators

and live in almost every habitat except for polar regions or the ocean. Beetles are usually around habitats that are especially dry. They got their name Coleoptera from the Greek words ‘koleos’ which means sheath or shield because of their hard exoskeleton and ‘ptera’ which means wings. The order Coleoptera can be distinguished by a variety of things. One key point that all other insects do not have is a hardened forewings called Elytra. The mouthparts of Coleoptera are mandibulate and used for biting
