Using Bicycles as an Alternative to Automobiles Essay Abstract: This paper basically shows the reasons to use the bicycle as an alternative mode of transportation. It will points out the benefits of the use of a bicycle. It will also show what is being done to get rid of the negative aspects of using a bicycle for transportation. Bicycling is one of the fastest growing forms of recreation. People are drawn to it for many reasons, being out in the fresh air, the thrill of speed, the physical challenge, along with many other things. But there can be many more uses for the bicycle. The use that this paper will focus on is transportation. The use of bicycles can greatly improve the economy of a nation. A comparison between the efficiency of the transportation systems of the United Stated and Japan points this out. In 1990 Americans spent 17. 9 percent of the GNP on transportation, whereas the Japanese spent only 10. 79 percent on transportation. This difference of nearly 7 percent, gives the Japanese economy much more money for investing in their future. Our Economy is not the only thing we should worry about, and it is also not the only thing that can be improved by the use of bicycles. There are several major problems that could be drastically reduced by the increased use of bicycles. Traffic would be a lot lighter due to the extremely small size of bicycles. It would also greatly reduce the wear and tear on our roads and highways, and therefore reduce government expenditure. But one of the most serious problems it would reduce is that of pollution and smog in out larger cities. There are more benefits to biking, though. There are benefits that come at a more personal level. Biking greatly improves ones health. It can be a way to exercise without taking much times out of ones schedule. The time one would spend biking to work serves two important purposes. One, getting to work, but also as a great form of exercise. Improved mobility in crowded situations. In downtown areas, biking to work may actually save time. Cars crawl through congested traffic, while bicyclists ride around it. The time it takes to park a car could also be factored in. Finding a parking space takes time and may be far away, while bikes are easy to lock and can be locked close to any destination. Personal economics are also important. Cars are expensive to own and operate. On top of the high prices for new cars, one must also pay for insurance, fuel, and maintenance. Not only is the price of a new bicycle much lower, they cost almost nothing to operate. Still with all of these benefits, many people choose not to consider a bicycle as a viable form for transportation. People feel that it is to time consuming, to inconvenient, and to dangerous. But there are things that can be done to change these facts. How a city is designed will play a large part in whether or not people choose to use bicycle as a form of transportation. Many of Americas large cities are not very friendly to the bicycle commuter. City streets should be wide enough to have room for a safe sized bike path that is separate from automobiles and pedestrians. This would improve the safety of bicycling. Another method that can be used is traffic calming. Traffic calming is a term that has emerged in Europe to describe a full range of methods to slow cars, but not necessarily ban them, as they move through commercial areas and residential neighborhoods. Traffic calming exists in certain downtown areas as a natural outcome of design initiatives to accommodate sizable special populations. Some the best examples of traffic calming are not in the United States. Traffic calming was originally introduced in the Netherlands and Germany, but is now being put to use in Denmark, Sweden, and the United Kingdom. In 1981, Germany set up six traffic-calming demonstration projects in various places with varying density. The initial reports showed that there was a reduction of speed from 23 mph to 12. The traffic volume remained constant, but there was a 60 percent decrease in injuries, and a 43 to 53 percent reduction in fatalities. In a recent survey, most people showed that if conditions where improved, more people use bicycles to commute. Things are being done to make things better. Private organizations are offering incentives and promotions, and our government is also making legislation to improve things. The need for bicycle and pedestrian provisions to be fully integrated into state and local plans and transportation policy documents has assumed even greater significance due to the ISTEA and the Clean Air Act Amendments of 1990. States were not required to have long-range transportation plans until ISTEA was passed, and Metropolitan Planning Organizations have had little or no control over project selection until now. Because of this fact, in the past, State highway agencies have dominated the spending of highway and transportation dollars. Plans developed at the city level would often contain many worthy transit and non-motorized projects. ISTEA makes a number of important changes. Both levels of government are now required to produce annual transportation improvement programs and long range transportation plans. These plans shall provide for the development of transportation facilities (including pedestrian walkways and bicycle transportation facilities) which will function as an intermodal transportation system. (Section 1024 (a) and 1025 (a)) State long-range plans are required to have consider strategies for incorporating bicycle transportation facilities and pedestrian walkways in projects where appropriate throughout the state. (Section 1025 (c)(3)) State long-range plans are also required to have a long-range plan for bicycle transportation facilities and pedestrian walkways for appropriate areas of the State, which shall be incorporated into the long-range transportation plan. People need to realize what the over use of automobiles is doing to our country. Our nations wealth is probably the greatest contributor to this problem. Americans generally feel that a car is a necessity and not a luxury. We are also spoiled with some of the lowest gasoline prices in the world. Some suggest an increase in gasoline taxes to drive people towards the use of alternative modes of transportation. Surveys shows that it would influence more people to not drive as frequently. But economists feel when the government imposes an intentional price floor on a common product, it can only hurt the economy. All of these things will help influence people to use alternative modes of transportation. But when it comes down to it, everyone must make a personal choice. Bicycles will probably never be as convenient as automobiles, and in this writers opinion, they shouldnt be. Commuting on a bike is a sacrifice in some ways, but we need to set our priorities straight. No legislation will do that for us. Boulder is probably one of the best place to get into the habit of frequently using a bicycle. In this community bikes are generally a lot more convenient than cars, in pretty much every aspect. Probably more than half of the time, I can get to wherever I want to in less time on a bike than in a car. Not to mention the time saved by not having to find a parking spot. This is accomplished by the use of good bike routes, underpasses, and having the right of way over cars. I use my bike almost daily, whereas I would probably use a car about once a week. It is also a lot more economical to ride a bike than to drive a car, especially on campus. As I already mentioned cars require several expenses, whereas bikes require almost none. Also on campus, if you have a car, you must pay for a parking permit. I plan to use a bicycle whenever and where ever possible. I think that everyone should own a bicycle and a least use it occasionally. I would like to inform other people of how easy it is to use a bicycle for transportation. References 1.

The Dark Side of Humanity Exposed in Robert Frosts Poetry Essay

The Dark Side of Humanity Exposed in Robert Frost's Poetry Robert Frost is often referred to as a poet of nature. Words and phrases such as fire and ice, flowers in bloom, apple orchards and rolling hills, are all important elements of Frost's work. These ‘benign' objects provide an alternative way to look at the world and are often used as metaphors to describe a darker view of nature and humans. In Frost's poetry, the depth is as important as the surface. The darker aspects of Frost's poetry are often portrayed through the use of symbolism, vivid imagery, and selective word choice. Frost's poems appear to be simple on the surface, yet upon further scrutiny the poems reveal themselves as elusive. Frost utilizes ordinary objects to create a deeper meaning. For example, the poem "Mending Wall", appears to be about the differences between two neighbors and their ideas on rebuilding a wall. On the other hand, the wall may be viewed, in a more general sense, as a symbol to represent all the antagonistic or mistrustful barriers that divide man from man. "The gaps I mean / No one has seen them made or heard them made / But at spring mending-time we find them there" (lines 9-11), illustrates the point that people become separated without even realizing it because we become so caught up in what is happening in our own lives. The darkness, held within the afore mentioned quotation, is the feeling of sadness. The fact that we do not take notice of one another creates a place that becomes more and more divided by differences. Likewise, the poem "Nothing Gold Can Stay" seems to represent the change of seasons. But further analysis reveals that the speaker is also paralleling the cycles of life with the change in seasons. "So dawn... ... light to the darker side of humanity in an extremely subtle way. Dark complexities are not obvious on the surface, however they are hidden throughout his poems in the form of symbols, imagery, and careful word choice. Frost's poetry acts as a metaphor for life. Upon first glance things look nice and orderly, but once the surface has been scratched the darker side becomes more apparent. Works Cited: Frost, Robert. "Mending Wall."

Medical diagnosis and treatment: Used to tag chemicals that accumulate in the body Phosphorous in bones, inject a tracer isotope. PET scanner produces an image of where the radiation collects, Shimmers patient. Deposits of plaque in the brain beta-myeloid show up on PET.This test allows researchers to monitor the effectiveness of new drugs on people. Orbital- 1. Each ring can only have 2 electrons, 2. 2nd and 3rd ring: four orbital, Outer ring can hold 8 3. Number of electrons increases from left to right per. Table Valence Shell- Number of electrons on outermost ring. Determines an atoms. Chemical properties. Valence number; number of additional electrons needed to fill the threshold, bonding capacity Chemical Bonds: two atoms with incomplete tortoiseshells react and donate electrons to complete their outer shells.Covalent Bond; two atoms share one or more pairs of outer shells. TWO or more atoms that share this bond are called Molecule. Electronegative- an toms attraction for shared electrons. Unpopular covalent bonds- electrons shared evenly between atoms. When atoms of a molecule equally pull on electrons. Happens in molecules of same elements. Methane also has a unpopular bond because carbon and hydrogen atoms rant that different. 02, H2O Polar covalent bonds- Molecules with different electromagnetisms attract.The unequal sharing of electrons, pulling shared negatively charges closer to a the more electronegative atom. H2O 0 Oxygen is slightly negative and Hydrogen slightly positive. Unequal sharing of electrons. Polar Molecule- polar covalent bond and V shape molecule. Slightly unequal distribution of charges. Slightly negative points at the V.

An Hydrogen Bond- a weaker bond that holds together briefly than separates. The charged regions in each water molecule are attracted to opposite lay charged regions on neighbor molecules. Because the positively charged region in this bond is always a hydrogen atom it gets its name. Each hydrogen of a water molecule can form a hydrogen bond with a nearby partial negative oxygen of another water molecule. Can bond to as many as 4 partners. Heat absorbed when they break, heat is released when they form. When it cools) Overarching Theme: The structures of atoms and molecules determines the way they behave. Reactant- Starting materials to the left of the arrow Product- to the right , results from chemical reaction. Cohesion-the tendency for molecules of the same kid to stick together. The evaporation of water is an upward force on the water within a leaf. Adhesion- the clinging of one substance to another. Counters the downward pull of gravity, water sticking to the veins of a plant.

The partial negative Oxygen in H2O is attracted to the slightly positive An+ sodium ions and the slightly positive hydrogen ions are attracted to the slightly negative chloride CLC- Dissociate-break apart into ions.Hydrogen ions H+ and Hydroxide OH- re very reactive. Some chemicals contribute H=, some remove. A impound that donates H+ to solutions is Acid- has a higher concentration of H+ them from a solution. More basic solution has higher hydroxide OH- and lower hydrogen H+. PH scale- potential odd hydrogen. O most acidic, 14 most basic. Each unit represents a lox times change. PH 2 has lox more H+ than pH 3. 7 is equal. PH of blood plasma is about 7. 4 Buffers-biological substances that minimize changes in PH. Blood buffers acid more than water. Acid Rain- precipitation with pH lower than 5. Ocean acidification- dissolving CA in seawater lowers oceans PH. CA reacts with water to create carbonic acid. Calcification, how some organism produce shells. Heat- the amount of energy associated with the movement of atoms and molecules in a body of water. Temperature- measures the intensity of the heat. The average speed of molecul es rather than the total amount of heat. Chapter 3. The molecules of cells (crabs, lipids, proteins, nucleic acid) Variety of polymers makes up for uniqueness of species. Living organisms built from the same 20 amino acids.Small molecules common to all are ordered into large molecules which vary from species to species. Carbon is attached to almost all molecules a cell makes and is unparalleled in its ability to form large and complex molecules. Organic Compounds- carbon-based compounds, Carbon has 4 electrons on the valence shell that holds 8, room for 4 covalent bonds. A great connecting point to line up 4 different directions. Hydrocarbons- compounds composed of only hydrogen and carbon. Methane, and propane are hydrocarbon fuels. Carbon skeleton- chain of carbon atoms in an organic molecule.Can be branched or unbranded May include double bonds and some are in rings. Isomers- Compounds with the same formula but different structural arrangements. Some molecules can have the same n umber of atoms, but have different three emotional shapes because of the location of the double bond. Sometimes harmful effects. One isomer of methamphetamine is the addictive illegal drug. The other is medicine for sinus congestion. The shape of a molecule determines the it functions in the body. Different shapes of isomers result in unique properties and greatly add to diversity of organic molecules.Hydrophilic- water loving, soluble in water. The first 5 functional groups act this way. Hydroxyl, carbonyl, carbonyl, amino, phosphate. Groups, hydroxyl, amino, and phosphate don't contain Carbon 1 . Hydroxyl- hydrogen atom bonded to oxygen, then binned to carbon skeleton. Alcohols. 2. Carbonyl- carbon atom linked with double bond to oxygen. If carbonyl group is at the end of a carbon skeleton its an allayed. If its within the chain it is called a ketene. 3. Carbonyl- carbon double bond to an oxygen atom and also a hydroxyl group.Carboxylic acids. Acetic acid like vinegar. 4. Amino gr oup-nitrogen bonded to two hydrogen and the carbon skeleton. Iconic compounds with an amino group are called Amines. The building blocks of proteins are called amino acids. They contain an amino and carbonyl group. 5. Phosphate group- phosphorous bonded to 4 oxygen atoms. Compounds with hostage groups are called organic phosphates- involved in energy transfer TAP. 6. Methyl group- Consists of a carbon bonded to three hydrogen. Compounds with methyl groups are called mentholated compounds.Macromolecules- crabs, proteins, nucleic acids might be gigantic, thousands of atoms. Polymers- Chains of smaller molecules. Consists of many identical or similar building blocks. Dehydration Reaction, a reaction that removes a molecule of water. Cells link monomers to make polymers this way. Links two monomers together Hydrolysis- the breaking down of macromolecules, digesting polymers to make monomers available. In digestion, the proteins are broken down into amino acids by hydrolysis, new protein s are formed in your body cells from these monomers in dehydration reactions.Both dehydration and hydrolysis require enzymes- specialized macromolecules that speed of the chemical reaction in cells. Proteins- are built of only 20 amino acids, DNA is built from Just 4 kinds of monomers called Nucleotides Carbohydrate- a class of molecules ranging from small sugar macroeconomics, to large polysaccharide Crab monomers are monsoons ( single sugars) glucose and fructose Disaccharide- cells construct one of these from two incarcerations by dehydration action. Sucrose most common, (glucose linked to fructose) from sugarcane and sugar beets.Maltose also common, beer, malted milk, High fructose corn syrup- the missionaries of sucrose Polysaccharide- are macromolecules, thousands of monomaniacs linked together by dehydration reactions. Glycogen, and cellulose. Starch- Storage polysaccharide in plants of all glucose monomers. Bans from which plant cells gather glucose for energy. Glycogen- ani mals store glucose this way, a different polysaccharide. Stored in your liver and muscle cells. Cellulose- tough walls that surround the cell, most abundant compound.Not a nutrient for humans because animals can't hydrology the linkages. The cellulose that phosphorous the body unchanged is called insoluble fiber. Bath tools are mostly cellulose, very hydrophilic absorbs water because of hydroxyl groups. Chitin- another polysaccharide used by insects and crustaceans to build their cells, Both starch and cellulose and polymers of glucose but have different shaped bonds. Starch is for sugar storage, cellulose is a structural polysaccharide that is the main material of the plant cell wall.Lipids- diverse compounds grouped together because of one trait: they don't mix ell in water. Hydrogen and carbon linked by unpopular covalent bonds. Lipids are Hydrophobic- water fearing Fat- a large lipid made up of smaller molecules: glycerol and fatty acids. Glycerol an local with three carbons, ea ch with a hydroxyl group (OH-). + a hydrocarbon chain (16-18 carbon atoms in Engel) the unpopular hydrocarbon is why fats are hydrophobic. Unsaturated fatty acid- has one fewer hydrogen atom on each carbon of the double bond.Saturated Fatty acids- Fatty acids with no double bonds in their hydrocarbon chain that have the maximum number of hydrogen atoms. Corn Oil, Olive oil, vegetable oil. Trans Fats- When you see hydrogenated vegetable oil, unsaturated fats have been converted to saturated fats by adding hydrogen. Health risks, contribute to cardiovascular disease plaque, Omega-3 acids protect A monounsaturated fat has fatty acid with a single double bond in its carbon chain. A Polyunsaturated fat has a fatty acid with several double bonds.Phosphoric- major component of cell membranes. Contain only two fatty acids attached to glycerol instead of three. Hydrophilic phosphate on one end and hydrophobic fatty acids on the other trap water inside, the membrane. Steroids- are lipids with four fused carbon skeleton rings. Cholesterol- common in animal cell membranes, starting material for making steroids and sex hormones. Proteins-a polymer arrangement of 20 amino acids 20 amino monomers. Amino Acids- all have an amino group and a carbonyl group, which makes it acid.Peptide Bond- Cells Join amino acids together In a dehydration reaction that that links the carbonyl group of one amino acid to the amino group of the next amino acid as a water molecule is removed. Both depicted and disaccharide the monomers are Joined by dehydration reactions. Denomination- polypeptide chains unravel loosing their specific shape and function The function of each protein is a consequence of its specific shape, which is lost when protein denatures. A proteins shape depends on four levels of structure Primary Structure- is its unique sequence of amino acids Secondary- Coiling of a polypeptide into local patterns..Cooling of the polypeptide chain in a secondary structure called an ALPHA HE LIX, leads to a BETA PLEATED SHEATH. Tertiary- the overall three dimensional shape of a polypeptide, determines the function of a protein. Quaternary structure- two or more polypeptide chains one macromolecule. Collagen, a fibrous protein with three helical polypeptides intertwined into a larger ripple helix. Incorrectly folded proteins = alchemies and Parkinson. If a genetic mutation changes the primary structure of a protein, how might this destroy the protein functions?The amino acid sequence affects the secondary structure, which affects the tertiary, then the quarterly, Thus the primary structure determines the shape of a protein, its function depends on shape. A chaos could eliminate function. Nucleic Acids Gene- the amino acid sequence of a polypeptide is programmed by a discrete unit of reticence. DNA- Deoxyribonucleic acid, one of the two polymers called nucleic acid. One of the too polymers called Nucleic acid. Provided direction for its own replication, as a cell divides its genetic instructions are passed to each daughter cell.RNA- ribonucleic acid, illustrates the main roles of the SE two types of nucleic acids the production of proteins. A gene directs the synthesis of an RNA molecule. RNA cell. Translates nucleic acid language into protein language Nucleic acids are polymers of nucleotides Nucleotides- the monomers that make up nucleic acids. Each contain 3 parts, At the center a five carbon sugar, negatively charged phosphate group, nitrogenous base. Each DNA nucleotide has one of four nitrogenous bases, Adenine, Thymine, Cytosine, ND Guanine. RNA contains, GAG U racial instead of thymine.

Special Education For School Leaders - 2294 Words

EDL 853 Special Education for School Leaders Case Study: â€Å"A Problem With Inclusion† Kevin L. Splichal Fort Hays State University Problem Identification and Analysis For this particular case, there are many issues which will cause problems for the school leader. All of which will need to be addressed in order for this student to feel welcomed and to also feel that he is getting the same educational opportunities as the other students in the building. This case presents many challenges, however, for the building leader. There are three key issues which are the basis for my resolution to the problem. First, it has been clearly identified that some of the instructors in the building have had a history of not accepting special†¦show more content†¦Namely, an American Sign Interpreter will be required for this student. Further, the student will need to feel accepted by his peers. This can be quite challenging for the building principal to facilitate, even for a building full of regular education students. Also, the teachers will need to be accepting of having this student in their classes, along with the interpreter. Finally, this case presents a challenging issue with the parents of the child as well. It will be critical for the parents to know that their child’s needs will be met through the IEP and that the building leader is in support of the IEP so that it is enforced. This is absolutely critical for the building leader because if the IEP is not constructed properly and if the IEP is not being followed, then legal ramifications could cause issues for me as the building leader. At any rate, the problem for me in this case is found in the three areas mentioned previously. One is the mindset of the teachers. Two is the mindset of the student. Three is the satisfaction of the parents. While these issues do not solely rest on my shoulders, it is my leadership which will determine how successful this inclusion will be for the student. Plan of Action The proposed plan of action to promote a resolution to this case is three-fold. First I will remedy the trouble with the instructors in my building by setting goals. It is apparent that many teachers are reluctant to accept special education
