Miranda vs. Arizon essays

Miranda vs. Arizon essays Ernesto Miranda, a 23 year old truck driver was arrested and charged for kidnapping, robbery and rape, in the year of 1966. Throughout the 1930s police were using force and not reading people their rights as we are used to in this day in age. Force was not as bad as it had been in the past but was still there and was conflicting with peoples rights. In a 5-4 decision the Supreme Court overturned Mirandas conviction. His conviction was overthrown because it was not right that prosecutors used statements made by defendants while in police custody, unless the police had already advised them of their rights; thus it was called the Miranda Rights. This case was later re-tried, and Miranda was convicted on the basis of other evidence, having nothing to do with his earlier trial. In the end, he served 11 years in prison. Since this case, the Supreme Court determined that criminal suspects cannot be arrested without being advised of their constitutional rights and what their responsibilities are. Police, before questioning, must warn the suspect or suspects that they have a right to remain silent. Also, any statement that they make can and probably will be used against them in a court of law. When being questioned they have the right to have an attorney present with them, and if the defendant cant afford an attorney one will be appointed to them without charge. In conclusion, the Miranda versus Arizona case made a significant difference in the police and court system in the United States. To think of it, if you are not read your rights, you could confess, but your confession would be meaningless because your rights were not read. Thus, even if you did the crime you could get away with it because you were not read your rights. ...

Why Christmas Trees Smell So Good

Why Christmas Trees Smell So Good Is there anything more wonderful than the smell of a Christmas tree? Of course, Im talking about a real Christmas tree rather than an artificial tree. The fake tree may have an odor, but its not coming from a healthy mix of chemicals. Artificial trees release residues from flame retardants and plasticizers. Contrast this with the aroma of a freshly cut tree, which may not be all that healthy either, but certainly smells nice. Curious about the chemical composition of Christmas tree aroma? Here are some of the key molecules responsible for the smell: -Pinene and -Pinene Pinene (C10H16) occurs in two enantiomers, which are molecules that are mirror images of each other. Pinene belongs to a class of hydrocarbons known as terpenes. Terpenes are released by all trees, although conifers are particularly rich in pinene. ÃŽ ²-pinene has a fresh, woody fragrance, while ÃŽ ±-pinene smells a bit more like turpentine. Both forms of the molecule are flammable, which is part of why Christmas trees are incredibly easy to burn. These molecules are volatile liquids at room temperature, releasing most of the characteristic Christmas tree smell. An interesting side note about pinene and other terpenes is that plants partially control their environment using these chemicals. The compounds react with air to produce aerosols that act as nucleation points or seeds for water, promoting cloud formation and conferring a cooling effect. The aerosols are visible. Have you ever wondered why the Smoky Mountains actually appear smoky? Its from the living trees, not campfires! The presence of terpenes from trees also affects weather and cloud formation over other forests and around lakes and rivers. Bornyl Acetate Bornyl acetate (C12H20O2) is sometimes called heart of pine because it produces a rich odor, described as balsamic or camphorous. The compound is an ester found in pine and fir trees. Balsam firs and silver pines are two types of fragrant species rich in bornyl acetate that are often used for Christmas trees. Other Chemicals in Christmas Tree Smell The cocktail of chemicals that produces Christmas tree smell depends on the species of tree, but many conifers used for Christmas trees also waft odors from limonene (a citrus scent), myrcene (a terpene partly responsible for the aroma of hops, thyme, and cannabis), camphene (a camphor smell), and ÃŽ ±-phellandrene (peppermint and citrus-smelling monoterpene). Why Doesnt My Christmas Tree Smell? Just having a real tree doesnt guarantee your Christmas tree will smell Christmas-y! The fragrance of the tree depends primarily on two factors. The first is the health and hydration level of the tree. A freshly cut tree is typically more fragrant than one that was cut some time ago. If the tree isnt taking up water, its sap wont be moving, so very little scent will be released. Ambient temperature matters, too, so a tree outdoors in the cold wont be as fragrant as one at room temperature. The second factor is the species of tree. Different types of tree produce different scents, plus some kinds of tree retain their fragrance after being cut better than others. Pine, cedar, and hemlock all retain a strong, pleasing smell after they have been cut. A fir or spruce tree may not have as strong a smell or may lose its scent more quickly. In fact, some people strongly dislike the odor of spruce. Others are downright allergic to the oils from cedar trees. If youre able to select the species of your Christmas tree and the smell of the tree is important, you might want to review tree descriptions by the National Christmas Tree Association, which includes characteristics such as odor. If you have a living (potted) Christmas tree, it wont produce a strong smell. Less odor is released because the tree has an undamaged trunk and branches. You can spritz the room with Christmas tree fragrance if you want to add that special aroma to your holiday celebration.
