The Environment Is Going To Hell
Number of Words: 285 / Number of Pages: 2
... 2000
species per weak, 300 per day, 10 per hour, another dead species every 6 minutes.
We're trashing the planet, washing away the topsoil, paving over our farmlands,
systematically deforesting our wildernesses, decimating the biota, and
ultimately killing ourselves.
The world is getting progressively poorer, and it's all because of populating,
or more precisely, over-population. There's a finite store of resources on our
pale blue dot, spaceship Earth, our small and fragile tiny planet, and we're
fast apporaching it's ultimate carrying capacity. The limits to growth are
finally upon us, and we' ...

Alternative Fuel Source
Number of Words: 349 / Number of Pages: 2
... capable of making America energy independent.
There is only one catch: the federal government prohibited the growth of hemp in 1938. There were also theories that the major energy industries of the late 30s collaborated to ensure a petroleum-based energy market. Regardless of laws, let us consider hypotheticals. Farmers would be practically guaranteed profit if they could grow hemp for biomass. It also would not take long for a measly 6% of the American landmass to start cultivating hemp – enough to replace our economy’s dependence on fossil fuels. As this energy crop grew, it would take CO2 ...

Cancer 3
Number of Words: 1345 / Number of Pages: 5
... which is also known as degenerative joint disease because it is characterized by joint degeneration and loss of cartilage. Cartilage is the shock absorbing material between joints. The weight-bearing joints such as the knees, hips, and spine, as well as the hands, are the joints most often affected by osteoarthritis. These joints are under much greater stress because of additional weight and continuous use (lifting, sports, support, movement). The concern that too much physical activity may lead to osteoarthritis is on the rise (2). Too much physical activity can lead to osteoarthritis si ...

Aspirin A Brief History
Number of Words: 607 / Number of Pages: 3
... ingredient, acetylsalicylic acid (ASA), is the commercially synthesized form of a naturally occurring compound whose uses can be traced back 2,000 years. The compound, called salicin, is found in the white willow tree. Around 200 B.C., Hippocrates, the Greek physician, discovered that chewing on willow bark could relieve pain and fever.
Although ASA was a proven pain reliever, no one really knew how it worked until more than 70 years after Hoffmann's discovery. In 1971, British pharmacologist John Vane discovered that the anti-inflammatory properties of ASA result from its ability to inhibit the ...

Plate Tectonics
Number of Words: 516 / Number of Pages: 2
... there was no way the continents could move through the rigid ocean floor.
During WWII, people started to explore the ocean floor and discovered evidence that would prove Wegener's ideas about land movement. The most interesting feature of the ocean was the ridges running along the ocean floor. It was discovered that earthquakes were abundant along the ridges that let magma flow from them. The magma would flow out these ridges and push the Earth away from it. This sea floor spreading was how the continents had moved over millions of years. The earth's crust is in mobile sections called plates, m ...

David Levinson: Seasons' Of A Man's Life
Number of Words: 4195 / Number of Pages: 16
... (the men's socio-cultural world,
their participation in their world and various aspects of themselves) is the
major component in Levinson's theory. The life structure for each person
evolves through the developmental stages as people's age.
Two key concepts in Levinson's model are the stable period and the
transitional period in a person's development. The stable period is the time
when a person makes crucial choices in life, builds a life structure around the
choices and seeks goals within the structure. The transitional period is the
end of a person's stage and the beginning of a new sta ...

Continental Drift
Number of Words: 726 / Number of Pages: 3
... history, and dynamics of the earth's crust. The earth's crust is formed of 13 continental plates. The boundaries of the zones are where tectonic activities occur, and where earthquakes and volcanic eruptions tend to happen. The plate tectonics theory was thought up in the 1960s and 1970s, with ideas taken from Wegener’s earlier thoughts. Earlier, Wegener and other scientists had noted that continental crust grows by additions and that a ridge in the middle of the ocean runs almost all the way around the world. It was also noted that continental plates tear apart, drift apart, and collide with each ...

... an it is no longer supported by the release of nuclear energy. If the star is particularly massive, then its core will collapse and in so doing will release a huge amount of energy. This will cause a blast waver that ejects the stars envelope into interstellar space. The result of the collapse may be, in some cases, a rapidly rotating neutron start that can be observed many years later as a radio pulsar. As a result of gravitational forces acting against the nuclear structure of the core of a fuel depleted star, tremendous shock wavers are generated which cause the outside layers of the star to be ...

Early Intervention And

... It manifests itself in varying degrees of severity, from profound to mild. Dr. Temple Grandin is an assistant professor at Colorado State University who was diagnosed as autistic at a young age, yet with proper help, she continued through school and earned a Ph.D.
Autism is usually diagnosed in the first three years of life. Early indication of autism may be seen in one or more ways. First, there is a lack of response to other people. This can be as simple as not acknowledging a mothers touch, or extreme distress at the touch of another. There are problems in speech and communication, such as echolal ...
