Every time one watches T.V. one cannot avoid hearing the commercials for “asbestos” and its dangers. “Have you been diagnosed with Mesothelioma?” the ad asks. This paper discuss what asbestos is and its applications in commercial industries. We will first define “asbestos”, describe the minerals defined, talk about its use in our economy and speak in depth about the serpentine mineral chrysolite.
The confusion over asbestos health risks is due to the term does not refer to a single mineral. Asbestos is an industry term that covers six different naturally occurring minerals. These minerals or “asbestiforms” all have a fibrous habit that is strong and flexible. The fibers are soft like fabric and can be spun into yarn or made into felts. This makes them useful as a fireproofing and insulation material.
The dolomite problem is a problem in how the formation of massive dolomite beds occurred. Dolomite is CaMg [CO3] 2 that differs from limestone in that magnesium substitutes for half the calcium. The problem is dolomite only forms in lagoons or extreme environments in smaller quantities today, the formation of dolomite beds is a mystery. It is hypothesized that these dolomites resulted from extra-terrestrial planting.
The aragonite problem is that aragonite is its more soluble than calcite. It would make sense that aragonite which is formed biologically in seashells not be formed at all. According to the one article I found the aragonite forms in magnesium rich seas. As magnesium increases the amount of calcite decreases until all that is formed is the more soluble aragonite.

Recently the North American Continent and Caribbean Islands was ravaged by a series of violent hurricanes. The hurricanes that hit the U.S. typically start off as severe storms on the west coast of Africa. As the storm hits the ocean, it will gather strength by feeding off the warmth and moisture of the ocean. Then, thanks to the Coriolis Effect, it gains rotation.
The Coriolis Effect is a phenomenon that causes fluids and air to curve over the earth’s surface. This occurs because the earth is rotating on its axis from west to east and it spins faster where the sphere bulges, the equator. As the hurricane spins an area of high pressure is created up top and low pressure on the bottom. The whole thing rotates around the eye of the storm.
I took a long time to realize what defined the perfect love. I picked many wrong people to love in the past. I thought love was defined on looks or who was popular. I thought those who were the right ones for me would be “strong enough” to control me, that I must date the bad guy to be cool. I was wrong.
I learned through trial and error what defined the perfect life partner. In fact, I know now I have that perfect life partner, my loving husband. Aaron is strong in character. He is open-minded and yet firm when defending those against wrongs. He is a good parent and a loving husband.
President John F. Kennedy was elected president in November 8 1960 against the then Vice President, Richard Nixon. Kennedy was the first Catholic and the youngest presidential candidate in history. At the time of his bid for presidency “anti-Catholicism was alive and well”, (Champion, Owen F) and for many Americans there was serious concern over having a Catholic president. He overcame this with his charisma during televised debates and beat Nixon in a landslide and on January 20th 1961. It was during his inaugural address he told Americans those famous words “Ask not what your country can do for you but what you can do for your country.” (The 6th Street Museum, Dallas)
President Kennedy was poised to begin his “New Frontier” policies. On March 1 1961 he formed the Peace Corps fulfilling for Americans a way for them to “do for their country,” and the world. He was a cultured president who held art viewings and socialites in the white house. He was also human and prone to err like the rest of us. During April 17 1961 the bay of pig invasion was launched. A thousand exiled Cubans attacked Cuba in a failed bid to overthrow Dictator Fidel Castro. (JFK Assassination Timeline) Kennedy bravely and publicly accepted the failure. In response to this disaster Kennedy created The Situation Room to filter military intelligence he would receive. This showed he was willing to act on his failing. Soon after Kennedy authorizes 400 U.S. Soldiers to go to Vietnam.
When King Cyrus of Persia conquered Babylon around 538 BCE, he wrote a decree that is often described as the first decree of human rights. The document describes the release of captives of Babylon and returning of them to their homeland. The second part of the reading is a document written by the Jews on their perspective of gaining freedom and the benevolence of the Persian king.
