Asbestos
What is asbestos you ask? Well asbestos is the name for a group of naturally occurring silicate minerals that can be separated into fibers. The fibers are strong, durable, and resistant to heat and fire. They are also long, thin, and flexible, so that they can even be woven into cloth. Because of these qualities, asbestos has been used in thousands if consumer, industrial, maritime, automotive, scientific and building products. During the twentieth century, some 30 million tons of asbestos were used in industrial sites, homes, schools, shipyards and commercial buildings in the United States.
There are several types of asbestos fibers, of which three have been used for commercial applications: (1) Chrysotile, or white asbestos, comes mainly from Canada, and has been very widely used in the US. It is white-gray in color and found in serpentine rock. (2) Amosite, or brown asbestos, comes from southern Africa. (3) Crocidolite, or blue asbestos, comes from southern Africa or Australia. Amosite and crocidolite are called amphiboles. This term refers to the nature of their geologic formation. Other asbestos fibers that have not been used commercially are tremolite, actinolite and anthophyllite, although they are sometimes contaminants in asbestos-containing products.
What are asbestos containing products? What is common to many asbestos-containing products is that they were used to contain heat (i.e. thermal insulation). It is impossible to list all of the products that have, at one time or another, contained asbestos. Some of the more common asbestos-containing products are pipe-covering, insulating cement, insulating block, asbestos cloth, gaskets, patching materials, thermal seals, refractory and boiler insulation material, transit board. Some more materials are asbestos cement pipe, fireproofing spray, joint compound, vinyl floor tile, ceiling tile, mastics, adhesives, coatings, acoustical textures, duct installation for heating, ventilation and air conditioning systems, roofing products, insulated electrical wire and panels, and brake and cloth assemblies. Some of these products contained a very high proportion of asbestos, while others contained small amounts.
Some people may ask why is asbestos still a problem. Well asbestos is still a problem. It’s because a great deal of it has been used In the United States and elsewhere. Also because man...

...s fiber. It is important that you not release fibers into the air or onto yourself when taking samples. Only you should be in the room when sampling is accomplished.
Repairing asbestos. Where and how to repair asbestos is different is all places. Pipe, furnace, and boiler insulation: when the insulation material will move at the touch of the hand or cover no longer feels firm and tight, the insulation is probably too deteriorated for repair. For material in this condition, call a professional. Repair by the homeowner should only be attempted, if at all, where the insulation is firm and cover tight, and there should be a minimum of holes or tears in the insulation (for example, no more than a one inch diameter opening in four lineal feet of pipe covering). For minor damaged areas such as this, you can obtain commercial products designed to fill holes and seal damaged areas in asbestos pipe insulation. These products area available from safety store suppliers.
In conclusion, asbestos is not something you want to mess with. It is very dangerous to your health and life. If you have asbestos, do not mess with it; always contact a professional who knows what they are dealing with.
Black Boy by Richard Wright and Separate Pasts: Growing up White in the Segregated South by Melton McLaurin are autobiographies based on segregation in the south in the early twentieth century. They are set in different times and different perspectives. Black Boy begins when the main character, Richard Wright, is four years old in the 1910’s. He grows up in Jackson Mississippi and moves north later in his life. In Separate Pasts the author is white and grows up in Wade, North Carolina in the 1950’s. Black Boy revolves around the experiences of Richard Wright as he grows in an extremely segregated city. Both blacks and whites accept the way things are. The more Wright grows up, the more he despises the way life is for Blacks in the south. When
“I would hurl words into this darkness and wait for an echo, and if an echo sounded, no matter how faintly, I would send other words to tell, to march, to fight, to create a sense of the hunger for life that gnaws in us all, to keep alive in our hearts a sense of the inexpressibly human.” (Richard Wright) In 1945 an intelligent black boy named Richard Wright made the brave decision to write and publish an autobiography illustrating the struggles, trials, and tribulations of being a Negro in the Jim Crow South. Ever since Wright wrote about his life in Black Boy many African American writers have been influenced by Wright to do the same. Wright found the motivation and inspiration to write Black Boy through the relationships he had with his family and friends, the influence of folk art and famous authors of the early 1900s, and mistreatment of blacks in the South and uncomfortable racial barriers.
In Richard Wright’s novel, Black Boy, Richard is struggling to survive in a racist environment in the South. In his youth, Richard is vaguely aware of the differences between blacks and whites. He scarcely notices if a person is black or white, and views all people equally. As Richard grows older, he becomes more and more aware of how whites treat blacks, the social differences between the races, and how he is expected to act when in the presence of white people. Richard, with a rebellious nature, finds that he is torn between his need to be treated respectfully, with dignity and as an individual with value and his need to conform to the white rules of society for survival and acceptance.
Frank L. Baum begins The Wonderful Wizard of Oz in Kansas, a land devoid of color and life, to show Dorothy’s dismal world. Her Aunt Em, who had once been a beautiful woman, has become as colorless as the gray and dried vegetation on her farm. When Dorothy is caught in a cyclone, she is transported to a colorful and lively world, but she desperately tries to return to the colorless farm. Inherently Dorothy knows that home is where one’s loved ones live not some beautiful illusion. However, on her journey home Dorothy becomes enticed by the illusion of the prosperous Emerald City and the Wizard of Oz. Dorothy, along with the friends who join her, willingly follow the Great and Terrible Wizard rather than looking within themselves to find their
them? Then do not be too eager to deal out death in judgement.”-J.R.R. Tolkien. Throughout history punishment for committing a crime is handed down by governing officials and depending on the type of defiance of the law can determine the severity of punishment handed to the criminal. Society looks at the unlawfully premeditated killing of one human being by another momentous in regard of crime. This act of lawbreaking has endured great debates on wether the current state of capital punishment is a moral and justified way of handling criminals being convicted of murder. Capital punishment by definition is the death penalty or execution is punishment by death.
Over six million African Americans moved from the South to the North in aspiration of seeking a better life and a fresh start. Black Boy, by Richard Wright, is the story of a young black boy, Richard, that is piloting himself through the Jim Crow South. Richard grew up in a primarily black community with his mom, Ella, and his younger brother, Alan. When he is finally introduced to the white population he is surprised to see how the blacks and whites interact. Due to his skin color, Richard is treated unfairly which makes it harder for him to thrive. As Richard comes of age, he is left to support his family. With no help or advice from his father, Richard labors many jobs in hopes of obtaining enough money to move himself and his family to
Exploring of Asbestos Asbestos (Greek a-, "not"; sbestos, "extinguishable") is a group of fibrous metamorphic minerals. The name is derived for its historical use in lamp wicks; the resistance of asbestos to fire has long been exploited for a variety of purposes. It was used in fabrics such as Egyptian burial cloths and Charlemagne's tablecloth, which, according to legend, he threw in a fire to clean. When asbestos is used for its resistance to fire or heat, the fibres are typically mixed with cement or woven into fabric or mats. It was used in brake shoes and gaskets for its heat resistance, on electric oven and hotplate wiring for its electrical insulation at elevated temperature, and in buildings for its flame-retardant and insulating properties, its tensile strength, flexibility, and resistance to chemicals.
...y comes from the Balcones Escarpment. Larger crushed rock from this area is used as a base layer for roads and buildings, to protect them from the shifting soils. Very pure limestone is procesed into lime, wich is then used in a wide variety of agricultural, industrial, and construction activities. Other rocks crushed for building materials include basalt, used for railroad track beds, and marble, used for fancy terrazzo floors.
Pulmonary Fibrosis is a condition where the lung tissue becomes thick and scarred. The thickening and scarring of the lungs makes it hard for the oxygen supply to be delivered throughout the body. The scarring can be caused by many different factors, but it is hard for doctors to figure out exactly what caused the onset of this disease. The damage caused by this disease cannot be repaired. Pulmonary Fibrosis usually affects the age group of forty to seventy years old. Men are more likely to develop this disease, but women can also get this disease. Pulmonary Fibrosis is not a transmittable disease. Little is actually known about how the disease develops. There seems to be a genetic connection and environmental factors that cause the disease to develop.
Frank Baum accurately presented ideas of occult symbolism in The Wizard of Oz, through aspects of illumination, enlightenment, and self-realization. This was accomplished by depicting multiple characters’ desires and needs, and others as guides to enlightenment. Baum would agree with the quote above, saying that The Wizard of Oz does focus on occult symbolism, and a journey to self-understanding. Everything one has experienced in life leads to self-realization and further, wisdom. Furthermore, the quote “Real power, for good or ill, lies with the women” (DATABASE) states that women have power as much as men do. The young heroine displays this by saving her male companions along her journey and completing her
The Death Penalty should be discontinued to the families, human rights, and statistics. The families of the victim and the family of the one, who committed the crime, have no closure at all. The death penalty is killing a human for being convicted of a terrible crime one family may think its right but both suffer by their lost ones. “Although true closure is never really possible for the families, studies have shown that the continual process, along with the returning to court for many years, force families to confront the gruesome details of the crime many times over, making it impossible to get on with their lives. As difficult as that is the question is weather the victims needs are met effectively by killing someone else and causing another family grief and pain as well as adding to the cycle of violence.” (Progress) As both families do not want to see each other because they all have pain and hate for one another. They both relive the last memories of their loved one and they can’t help but cry and stare at the pictures they were once happy in. The families both have sadness when its their loved ones birthday. If the victim is married or have kids, their kids suffer and the husband/wife suffer as well. Although the families will never get there loved one back they still suffer on what had happen. Both families blame one another for having to take flowers, to their dead family member or visit their family member in a cemetery because of what happen. None of them is truly happy that they lost a family member. The families miss the person who seemed so happy, and also know that they are in a better place watching over them. Although the families aren’t happy about losing them, but are relieved to know that nothing else can hurt them. As one family feels sorry for the other family, there could be the family that doesn’t care what happens but wants everyone to suffer the way they are suffering about the tragic death of one family member.
He believes that the way in which sexuality is expressed, by different philosophers, is the wrong way to think of sexuality. Through his philosophy his main goal is to question sexuality itself and for society to question the idea of the sexuality options given. Foucault has participated in many revolution such as women and gay revolutions and in the movements pertaining to the solitary prisoners faced in the 70’s. Foucault believed in observing and participating in social movements. He believed that in order to understand the present ies, history needed to be explained and observed. Being able to see historical movements, in a linear matter, gives us the ability to see the problems in the present day. When describing his books, Foucault often referred to them as the history of the present. Foucault ultimately believed that in order to understand the present time one must look at past events. The example of expressing the past in order to understand the future can be further explained in his book, History of sexuality. History of Sexuality is also used by Foucault to further explain sexuality and his critique of the repressive hypothesis. In Foucault’s book he speaks on many historical events, as well as the politics of truth, the origination of confession and lastly the explosion of sexuality in a form of
...farm, mowing the grass, feeding the animals, and harvesting the garden. The only real value of the farm, the close contact with nature, can be had for no cost. Thoreau found more freedom in his small hut by the pond where he was truly free from the trivial life of living in a village. He was free from the commercial rat race and was able to let himself be roused by nature.
For a long time in history, racism has played an important role. In America, racism practically shaped our nation how it is today. Richard Wright wrote two novels about how racism was portrayed back in the early twentieth century. These novels, Black Boy and Native Son both explore the racism that African Americans experienced. How two of the protagonists experienced racism firsthand, how society viewed racism and Wright's own views on racism in the North are explored in this essay.
