Also had pedal on front wheel which gave it movement. 1885 Over a twenty-year span, the British brought the bicycle to its present form, thanks mainly to James Starley of the Coventry Sewing Machine Company. In 1885 the Starley Rover safety bike was born Early 1770 The unknown inventor accomplished dry land skating by nailing wooden spools to strips of wood and attaching them to his shoes. 'Skeelers' was the nickname given to the new dry-land skaters The late 70's through mid 80' - A second big skating boom occurred with the marriage of disco and roller-skating. Over 4,000 roller-discos were in operation and Hollywood began making roller-movies. 1979 - Scott Olson and Brennan Olson, brothers and hockey players who lived in Minneapolis, Minnesota, found an antique pair of roller skates. It was one of the early skates that used the 'in-line' wheels rather than the four-wheeled parallel design of George Plimpton. Intrigued by the in-line design, the brothers began redesigning roller skates, taking design elements from the found skates and using modern materials. They used polyurethane wheels, attached the skates to ice hockey boots, and added a rubber toe-brake to their new design. ...

Microbiology - Lab Report Example Thus, bacterial identification is the foremost step to accomplish further investigation procedures. The three preliminary steps for the analysis procedure comprise principal isolation, staining and biochemical reactions as the sample may contain diverse microorganism belonging to different species. Identification is based on the kind of Gram reaction shown by the organism. This is the most significant staining, also called differential staining performed to categorize microbial population into two groups the Gram positive and Gram negative organisms. The reaction displays the characteristic of the cell wall of the bacterial species. If the bacterial species possess thick peptidoglycan layer, it displays Gm +ve differential staining and if the microorganism possesses thin or single layer of peptidoglycan, it takes up the counter stain Safranin of the Gram reaction. Counter stain Safranin is added to the reaction after washing the Gram stain with alcohol. Since, Gram positive organisms possessing thick peptidoglycan retains the stain while Gram negative organisms possess thin peptidoglycan cell wall becomes colorless and therefore takes up the counter stain when stained with Safranin. The given sample displayed Gm-ve character of the organism. The cellular morphology is rod shaped (â€Å"Analytical solution for laboratories†; â€Å"Antimicrobial Therapy†; William, 2000). Part 2 MAC plate- Pink Color is observed on the culture plate, indicating that the unknown organism is lactose fermenting. Triple sugar iron agar test (TSI)- TSI contains glucose, sucrose and lactose together with iron and phenyl red as a pH indicator. On fermentation of sugar, the pH of the medium changes indicated by the color change from red to yellow. Sodium thiosulfate present in the medium is reduced to H2S which in turn reacts with the ferric ions to give sulfide of iron which turns the medium black. In the present condition the isolate is capable of fermenting Lactose and al so produces H2S (William, 2000). Imvic test TSI test is followed by Imvic test, to test the ability of the strain to produce enzyme tryptophanase. Unknown culture is unable to produce the enzyme typtophanase (William, 2000). Hydrogen sulfide test The unknown sample is able to produce H2S. Urease test Urease enzyme is responsible for the hydrolysis of urea to generate CO2 and ammonia. The unknown culture shows the presence of urease enzyme as indicated by the pink color (William, 2000). Motility indole ornithine (MIO) test MIO is a semisolid medium which is used to test the motility of the given organism. The medium contains indole and ornithine. No change in color was observed as the medium remained yellow indicating negative indole test. On the other hand, deep purple color was obtained indicating positive test for ornithine. Further, diffused growth was observed, which extended from the stab line forming cloudiness displaying the motile behavior of the organism (William, 2000). Ci trate test The unknown culture was grown on sodium citrate medium containing ammonium salts as the nitrogen source and bromothymol blue as the pH indicator. The test displays the ability to generate citritase enzyme, responsible for the breakdown of citrate into oxaloacetate and acetate. Sodium bicarbonate and ammonia are produced during the process which changes the pH of the medium, indicated through the change in color from green (neutral) color to blue (alkaline) (â€Å"

My city should enact an ordinance prohibiting businesses from distributing plastic shopping bags with retail sales - Essay Example c. Environmental degradation This section will highlight how plastic paper bags contribute to environmental degradation and what can be done by authorities to reduce the effects of plastic bags on the environment. d. Dangers to human life. This section will discuss how plastic bags endanger human life. The section will also provide examples of situations whereby human life is endangered by plastic bags. e. Summary This part will give a summary of what is contained in the paper. The section will also give a few suggestions on how to end the hazards caused by plastic bags. f. Works Cited This section will list all the sources that were used and consulted during this research. Introduction Non biodegradable substances are used in the manufacture of plastic bags. Therefore, they do not decompose and are quite durable, during which time they separate into toxic particles which contaminate waterways and the soil. Plastics are large molecules that consist of units known as monomers. In plas tic bags, the units of monomers are known as ethylene. Plastic bags have been shown to pose a hazard to marine life, human life and contribute to environmental degradations. ... Manufacturing a new plastic shopping bag is cheaper than recycling, the reason why more and more bags are being manufactured as people shop. This increases dependency on foreign oil, which is used in the manufacture of plastic bags. Natural resources are depleted as the earth is extracted and destroyed in order to mine oil to manufacture plastic bags that are used, on average, for 10 minutes then dumped. Traditionally, plastic bags are made from polyethylene. Polyethylene is in turn, made up of monomer ethylene chains derived from petroleum and natural gas. Petroleum and natural gases are non renewable natural resources. Therefore, their products are getting costlier or diminishing every day with increased mining (Stillwell 63). Petroleum and natural gases are vital for everyday lifestyles as they are used in lighting, heating, transport and as raw materials in factories. With the current circumstances without a viable option for energy sources, petroleum and natural gas supplies sho uld be controlled to avoid a situation where industries would grind to a halt. It has been documented that the number of barrels of oil used globally are between 60 to 100 million annually in the manufacture of plastic bags (Stillwell 63). This oil could be put to better use. Therefore, what was a short-lived convenience for shoppers soon becomes an ecological hazard to all in habitants of the earth. Hazards Faced by Marine Life Due to Plastic Bags More than one million marine reptiles, birds and mammals succumb to plastic bag-related deaths each year (Brown 1). Some get entangled in them, losing limbs or life, while others ingest them. Sea turtles, for instance, consume plenty of jelly fish in their

James Joyces Dubliners - Adolescent Initiation Portrayed in Araby Essa

Adolescent Initiation Portrayed in Araby  Ã‚  Ã‚  Ã‚   "Araby" tells the story of an adolescent boy's initiation into adulthood. The story is narrated by a mature man reflecting upon his adolescence and the events that forced him to face the disillusioning realities of adulthood. The minor charac ­ters play a pivotal role in this initiation process. The boy observes the hypocrisy of adults in the priest and Mrs. Mercer; and his vain, self-centered uncle introduces him to another disillusioning aspect of adulthood. The boy's infatuation with the girl ultimately ends in disillusion ­ment, and Joyce uses the specific example of the boy's disillusionment with love as a metaphor for disillusionment with life itself. From the beginning, the boy deludes him ­self about his relationship with Mangan's sister. At Araby, he realizes the parallel between his own self-delusion and the hypocrisy and vanity of the adult world. From the beginning, the boy's infatuation with Mangan's sister draws him away from childhood toward adulthood. He breaks his ties with his childhood friends and lux ­uriates in his isolation. He can think of nothing but his love for her: "From the front window I saw my companions playing below in the street. Their cries reached me weak ­ened and indistinct and, leaning my forehead against the cool glass, I looked over at the dark house where she lived." The friends' cries are weak and indistinct because they are distant emotionally as well as spatially. Like an adult on a quest, he imagines he carries his love as if it were a sacred object, a chalice: "Her image accompanied me even in places the most hostile to romance†¦. I imagined that I bore my chalice safely through a throng of foes." Even in the active, distracting market... ...se and that he was someone else. His disillusionment with love is then extended to life in general. Seeing the last rays of hope fading from the top floors of Araby, the boy cries: "I saw myself as a crea ­ture driven and derided by vanity; and my eyes burned with anguish and anger." At last he makes the connection—by deluding himself, he has been hypocritical and vain like the adults in his life. Before these realizations he believed that he was driven by something of value (such as purity of love), but now he realizes that his quest has been in vain because honesty, truth, and purity are only childish illusions and he can never return to the innocence of childhood.

Death of naturalist Essay -- English Literature

Death of naturalist This poem is a fertile mixture of imagery, sounds and an impression created by nature on people’s mind. Heaney sensualises an outstanding fear of the physical wonders of the world. He vividly describes his childhood experience that precipitates his change as a boy from the receptive and protected innocence of childhood to the fear and uncertainty of adolescence. As he wonders along the pathways of salient discovery, Heaney’s imagination bursts into life. The title of the poem is amusingly ironic – by a naturalist we would normally think of someone with expert scientific knowledge of living things and ecology. The poem ‘Death of a naturalist’ has quite a lot of emotional images because it’s the poet’s memory and he is reminiscing. There are a number of poetic devices to create an image. Firstly, the poet uses the metaphor ‘in the heart of the town land’ to add interest to the poem. He also uses languages like ‘sweltered’ and ‘punishing sun’ to convey to the reader the hot summers day Heaney remembers. Nature is also brought up in the poem by ...
