Earth and Environmental Science Environmental Impact Statement By Byron Smith Actual Development “Hume Coal Mine “ In the Berrima area located in the NSW southern highlands there has been a proposed coal mine. This coal mine will consist of large stockpile near Berrima (town centre), train loading facilities, a train line and an underground mine. The Hume coal mine is too “extract 3.5 million tonnes of coal… in the next 19 years”. The public have protested about this proposed mine as…

“If you look at the evolution and leap forward to 11 years from now, I think we will be using all the knowledge in molecular biology, and cancer biology combined with imaging, It will be images, combined with genes, tumor markers and patient data.” (Liselotte Hojgaard, MD, professor of medicine and technology at the University of Copenhagen) The science of radioactivity has existed for many decades since it’s discovery. While often perceived as a risky and dangerous practice, artificial…

2.4.1 Magnesium Properties Magnesium is the essential to human body and naturally it is found in bone and it is the fourth cation in human body. Magnesium is a lightweight metal with a density of 1.74 g/cm3. The fracture toughness of magnesium are greater than the ceramic materials such as hydroxyapatite. Elastic modulus and compressive yield strength of magnesium are similarly to human bone. The disadvantages of magnesium is it has low corrosion resistance and stimulatory effects on the growth…

waste product from nuclear weapons plants and nuclear power plants) to create highly charged radioactive beams. A new technique, developed by the Titan Corporation, uses conventional electricity and an electronic accelerator instead of radioactive isotopes. Titan devised its SureBeam irradiation technology during the 1980s, while conducting research for the Star Wars antimissile…

When we think of the ancient classical civilization of the Romans, what comes to mind? Perhaps it’s the amazing architectural feats, or rather the advanced forms of government that we still use to this very day? I submit that neither is as spectacular as the ancient underground catacombs that hold the mass graves of around 2000 skeletons. After watching the NOVA program (titled Roman Catacomb Mystery) on this specific catacomb, I found several interesting aspects of the graves that include, the…

We know that radiation is harmful to us, even the sun’s UV waves are know to cause skin cancer. Than why, you may ask, do you think radiation is so good for us when it is so bad for our health? Well, for starters the two biggest types of power right now are Nuclear and Coal. If you have been keeping up with the environmental status coal is not helping the climate. People want to enjoy technology, but that costs power, which comes from coal. How do we balance these two, protecting the…

facilities and committees were created because of the need for nuclear power research. The National Defense Research Committee, the NDRC, was created in 1940 to fund and influence nuclear research. Much research was done in university labs and focused on isotope separation. Following the NDRC the Office of Scientific Research and Development, the OSRD, was established and branched into the Uranium committee. Among the many, these committees furthered the research devoted to nuclear energy which…

The 20th century saw some of the bloodiest battles ever fought along with, It saw a huge surge in world population and introduced us too technology that was only previously dreamt of. In the 20th century, we went from communicating via mail to communicating instantly across the world using wireless phones. We went from hands on fighting, using single fire rifles to creating huge bombs that can wipe out cities Life expectancy skyrocketed about 60 percent in Canada in just one century, it went…

In the period following World War II, Britain’s position in the world changes drastically as it not only lost its status as a great imperial power, but itt also experienced a number of social and political changes. Fears and anxieties regarding the decline of Britain’s global significance following the end of the war are revealed in literature that examines and critiques the responses to decline. In John Christopher’s The Death of Grass, the destruction of all grasses by a virus removes the…

“Studies of the skeleton, dubbed the Amesbury Archer for the archery gear that accompanied his remains, showed he had lost one knee, and infection had entered his bones. And intriguingly, analyses of his tooth chemistry revealed a blend of strontium isotopes that suggested his original home was far away in the Alps… the Amesbury Archer was one of a stream of visitors hoping to find relief at Stonehenge.”. This is a perfect example of…
