Bone is a specialised, strong, flexible connective tissue and is the main component of the adult skeleton. Unlike hyaline and fibrocartilage, bone is supplied with nerves and blood vessels. Epiphyseal veins carry the blood away from the long bones of the body and periosteal arteries, which are also accompanied by nerves, carry blood to the bones. It provides support and gives the structural framework to the body, it acts as a protective cover for internal organs such as the heart, brain and lungs, it provides sites of attachment for muscles, it stores minerals such as calcium and phosphate and it contains cavities where bone marrow produces blood cells. Bone is made up of two main components, cells and the bone matrix. There are four different types of cells in the bone; osteogenic, osteocytes, osteoblasts and osteoclasts of which…
Boyan Slat is a Dutch entrepreneur and founder and the CEO of The Ocean Cleanup project. This invention consists of a V-shaped boom that is situated in a gyre. This will allow the ocean to clean itself when the water circulates into the boom. Attached to the boom is a non-permeable net. It does not allow anything to pass through and will capture all the plastic that floats to the top of the water. It lets sea life swim under it and does not prevent proper water flow. In the center of the V there is a platform that takes in all the plastic and holds it until it is picked up by humans. While this technology does work for retrieving all plastic that floats to the top of the water, we still need to worry about that water below that level. Also, this technology is great in the sense that the ocean can clean itself but we also have to clean other areas of water that have been polluted by trash such as lakes and rivers because someday that trash will be apart of the GPGP and we need to prevent it before this…
Beginning in the southeastern Vic city of Torquay and stretching a full 244 kilometres to the city of Allansford near Warrnambool, lies what has been labeled by many as the greatest example of scenic coastal road engineering that exists: The Great Ocean Road (TGOR).…
Up early, the surface of the water was like glass, I unloaded the fly rod and headed back to the water with the dogs. Knowing that the prolific Utah Chub was a major food source in the reservoir, I tied a bunch of white and gold streamers in the weeks leading up to departure. I tied one on and made a couple casts, still targeting stumps and their roots. Just as the fly neared shore, a cutthroat shot out from under the stump and grabbed my fly. Unfortunately, it was a short lived flight as the fish shook its head and gained its freedom.…

Norwalk has a long and storied history. It has faced many changes and challenges over the years since its founding in 1651.…
Could you imagine the city of Chicago being an agricultural place, without the huge towers and buildings there today? The I&M Canal made Chicago the city it is today by creating a greater opportunity for trade. How did the I&M Canal affect people before and after it was built? The I&M Canal attracted many immigrants, and improved imports and exports.…
In the short stories the "Open Boat" written by Stephen Crane and "Cathedral" written by Raymond Carver, tell a tale about different groups of people who go through life changing experiences and come out in the end as a stronger community. Everywhere we look communities surround us all. From our families and friends to the people we go to school with. Communities make up the essence of our everyday life.…
It'd been a long time since he'd been there, but since the book was based in Charm City, it made perfect sense that his editor sent him back for a book signing.…
Running through the city of Cleveland and other neighboring towns, the Cuyahoga once filled these cities with not only clean water but also a tremendous view. It was beautiful place to be. However, when industrialization took hold in the late 1800’s and early- to mid-1900’s, the Cuyahoga River soon became the dumping ground for waste materials and debris created by the factories, steel mills, and other businesses that built up along the banks of the river.…
Global Issue / Community Issue - The Chesapeake Bay is a known body of water if you live in Maryland. During the summer it is a common hang out spot, it is even home to many animals and plant life. But what many people don’t realize is how serious of a problem we will have if we don’t start to clean it up.…
During the late eighteenth and early nineteenth centuries, the new nation known as the United States of America began to develop plans to improve transportation into the interior and beyond the great physical barrier of the Appalachian Mountains. A major goal was to link Lake Erie and the other Great Lakes with the Atlantic Coast through a canal.…
The international waterway known as the Panama Canal allows ships to cut voyages by thousands of miles. Not having to go all the way around the southern tip of South America cuts about 8000 miles from a trip, from Matt Rosenburg, “Geographyabout.com” http://geography.about.com/od/specificplacesofinterest/a/panamacanal.htm accesed 1/2/13. The Panama Canal is obviously a very important perk for any country wanted to trade goods around that area, it was very hard to maintain but well worth it. Many people know that the United States succeeded in opening the canal in 1914 but what people actually don’t know is that England tried to open it originally and failed. Around 22,000 people died during the process of building the canal, it was somewhat worth it though because voyaging all the way around the continent wasn't exactly safe.…
The Erie Canal finished in 1825 went from Lake Erie to the Hudson River and the Atlantic Ocean. It was built in the search for a better way of transportation from the Old Northwest to the East Coast. The Erie Canal seemed impossible to build by many but it was eventually built overcoming some challenges along the way. The Erie Canal had many positive effects on America but had a few negative consequences. The difficulty in the transportation of goods from Old Northwest to the East Coast lead to the construction of the Erie canal which seemed impossible but is completed successfully and impacted America in many ways.…
Hama in Syria is famous for these water wheels, initially built by the Romans in what must be one of the most impressive engineering feats ever seen in a while. The current turns the wheels which contain small buckets which fill up with water and then spill out over to the aqueduct to its side... basically how to pump water from the river without using a pump. Apparently the wheels are all a-spin in the summer when there's more water.…
