A Short History of the Ball of Goo Called Silly Putty

A Short History of the Ball of Goo Called Silly Putty Silly Putty, one of the most popular toys of the 20th century, was invented accidentally. Find out what a war, an indebted advertising consultant, and a ball of goo have in common. Rationing Rubber One of the most important resources needed for World War II war production was rubber. It was essential for tires (which kept the trucks moving) and boots (which kept the soldiers moving). It was also important for gas masks, life rafts, and even bombers. Beginning early in the war, the Japanese attacked many of the rubber-producing countries in Asia, drastically affecting the supply route. To conserve rubber, civilians in the United States were asked to donate old rubber tires, rubber raincoats, rubber boots, and anything else that consisted at least in part of rubber. Rations were placed on gasoline to hinder people from driving their cars. Propaganda posters instructed people in the importance of carpooling and showed them how to care for their household rubber products so they would last the duration of the war. Inventing a Synthetic Rubber Even with this home-front effort, the rubber shortage threatened war production. The government decided to ask U.S. companies to invent a synthetic rubber that had similar properties but that could be made with non-restricted ingredients. In 1943, engineer James Wright was attempting to discover a synthetic rubber while working in General Electrics laboratory in New Haven, Connecticut when he discovered something unusual. In a test tube, Wright had combined boric acid and silicone oil, producing an interesting gob of goo. Wright conducted a multitude of tests on the substance and discovered it could bounce when dropped, stretch farther than regular rubber, didnt collect mold, and had a very high melting temperature. Unfortunately, though it was a fascinating substance, it didnt contain the properties needed to replace rubber. Still, Wright assumed there had to be some practical use for the interesting putty. Unable to come up with an idea himself, Wright sent samples of the putty to scientists around the world. However, none of them found a use for the substance either. An Entertaining Substance Though perhaps not practical, the substance continued to be entertaining. The nutty putty began to be passed around to family and friends and even taken to parties to be dropped, stretched, and molded to the delight of many. In 1949, the ball of goo found its way to Ruth Fallgatter, an owner of a toy store who regularly produced a catalog of toys. Advertising consultant Peter Hodgson convinced Fallgatter to place globs of the goo in plastic cases and add it to her catalog. Selling for $2 each, the bouncing putty outsold everything else in the catalog except for a set of 50-cent Crayola crayons. After a year of strong sales, Fallgatter decided to drop the bouncing putty from her catalog. The Goo Becomes Silly Putty Hodgson saw an opportunity. Already $12,000 in debt, Hodgson borrowed another $147 and bought a large quantity of the putty in 1950. He then had Yale students separate the putty into one-ounce balls and place them inside red plastic eggs. Since bouncing putty didnt describe all of the puttys unusual and entertaining attributes, Hodgson thought hard about what to call the substance. After much contemplation and numerous options suggested, he decided to name the goo Silly Putty and to sell each egg for $1. In February 1950, Hodgson took Silly Putty to the International Toy Fair in New York, but most people there did not see the potential for the new toy. Luckily, Hodgson did manage to get Silly Putty stocked at both Nieman-Marcus and Doubleday bookstores. A few months later, a reporter for The New Yorker stumbled across Silly Putty at a Doubleday bookstore and took home an egg. Fascinated, the writer wrote an article in the Talk of the Town section that appeared on August 26, 1950. Immediately, orders for Silly Putty started pouring in. Adults First, Then Children Silly Putty, marked as The Real Solid Liquid, was at first considered a novelty item (i.e. a toy for adults). However, by 1955 the market shifted and the toy became a huge success with children. Added to bouncing, stretching, and molding, kids could spend hours using the putty to copy images from comics and then distort the images by bending and stretching. In 1957, kids could watch Silly Putty T.V. commercials that were strategically placed during The Howdy Doody Show and Captain Kangaroo. From there, there was no end to the popularity of Silly Putty. Children continue to play with the simple gob of goo often referred to as the toy with one moving part. Did You Know... Did you know that astronauts on the 1968 Apollo 8 mission took Silly Putty with them to the moon?Did you know that the Smithsonian Institution included Silly Putty in its exhibit on the 1950s?Did you know that Binney Smith, the makers of Crayola, bought the rights to Silly Putty in 1977 (after Peter Hodgson passed away)?Did you know that you can no longer copy images onto Silly Putty from the comics because of the change in the inking process?Did you know that people did finally discover numerous practical uses for Silly Putty, including as a balance for a wobbly piece of furniture, lint remover, hole stopper, and a stress reliever?

Definition of Salon

Definition of Salon Salon, derived from the French word salon (a living room or parlor), means a conversational gathering. Usually, this is a select group of intellectuals, artists, and politicians who meet in the private residence of a socially influential (and often wealthy) person. Pronunciation: sal ·on The Gertrude Stein   Numerous wealthy women have presided over salons in France and England since the 17th century. The American novelist and playwright Gertrude Stein (1874-1946) was known for her salon at 27 rue de Fleurus in Paris, where Picasso, Matisse, and other creative people would meet to discuss art, literature, politics and, no doubt, themselves. (noun) - Alternately, the Salon (always with a capital S) was the official art exhibition sponsored by the Acadà ©mie des Beaux-Arts in Paris. The Acadà ©mie was begun by Cardinal Mazarin in 1648 under the royal patronage of Louis XIV. The royal Acadà ©mie exhibition took place in the Salon dApollon in the Louvre in 1667 and was meant for only members of the Academy. In 1737 the exhibition was opened to the public and held annually, then biannually (during odd years). In 1748, a jury system was introduced. The jurors were members of the Academy and previous winners of Salon medals. The French Revolution After the French Revolution in 1789, the exhibition was opened to all French artists and became an annual event again. In 1849, medals were introduced. In 1863, the Academy exhibited the rejected artists in the Salon des Refusà ©s, which took place in a separate venue. Similar to our annual Academy Awards for Motion Pictures, the artists who made the cut for that years Salon counted on this affirmation by their peers to advance their careers. There was no other way to become a successful artist in France until the Impressionists courageously organized their own exhibition outside the authority of the Salon system. Salon art, or academic art, refers to the official style that the juries for the official Salon deemed acceptable. During the 19th century, the prevailing taste favored the finished surface inspired by Jacques-Louis David (1748-1825), a Neoclassical painter. In 1881, the French government withdrew its sponsorship and Socià ©tà © des Artistes Franà §ais took over the administration of the exhibition. These artists had been elected by artists who had already participated in the previous Salons. Therefore, the Salon continued to represent the established taste in France and resist the avant-garde. In 1889, the Socià ©tà © Nationale des Beaux-Arts broke away from the Artistes Franà §ais and founded their own salon. Here Are Other Breakaway Salons Salon des Aquarellistes (Watercolorists Salon), begun 1878Salon de lUnion des Femmes Peintres et Sculpteurs (Women Painters and Sculptors Union Salon), begun 1881Salon des Indà ©pendants, begun 1884Salon des Graveurs (Printmakers Salon), begun 1900Salon dautomne (Fall Salon), begun 1903Salon de lÉcole Franà §aise (French School Salon), begun 1903Salon dHiver (Winter Salon), founded in 1897, first exhibition 1904Salon des Arts Dà ©coratifs, begun 1905Salon de la Comà ©die Humaine, begun 1906Salon des Humeuristes begun 1908

Principle of Management - Essay Example etent leader conducts internal analyses, reviews the external market and competitive environments and also considers the current state of human capital in the employee population. This report highlights a series of specific tasks which can lead to the identification of problems in the construction business unit as well as the tasks necessary to move the business forward and build profit and a better retention model. The issues which are leading to rather flat growth and improvement must be identified in order to give the construction unit a competitive edge in its industry. Competitors have managed to perform better in relation to profit increases and maintaining a contented workforce who are not as apt to seek other job opportunities. This means that the construction industry, as a whole, provides opportunities for advancement in areas of profit and turnover if these issues can be successfully identified. The first task necessary in this goal is to conduct an analysis of the company’s strengths and weaknesses in areas of human resources, the internal use of finances, marketing, and job design. This can be accomplished using the SWOT analysis template, designed to review the internal and external business environment in order to give the manager a snapshot of what is occurring at the business and employee level. â€Å"SWOT analysis remains a major strategic tool for listing the strengths and weaknesses of the organisational unit and can translate them into value† (Coman and Ronen, 2009, p.5677). For example, it is necessary to review all functional and inter-related departments to essentially audit how they are interacting at the interpersonal and business levels. Administrative groups may not be providing the necessary support or encouragement needed for lower-level employees within the organisation, thus reducing morale. The SWOT analysis would identify poorly-function ing business units as a weakness and give the manager a guideline by which to make internal

Business - Affirmative Action Research Paper Example | Topics and Well Written Essays - 1750 words

Business - Affirmative Action - Research Paper Example It is an act to increase the representation of minority by giving them preference on the basis of gender, color, origin, sexual orientation etc. Moreover, this act is also done to increase the participation of the under representative part of the society to showcase what they are capable of. Historical Background: General Background History The term ‘affirmative action’ was first used in 1935 in a National Labor Relations Act (29 U.S.C.  §Ã‚ §151–169). The usage for it was not for race but to provide remedy for employers to avoid discrimination of union members. However, in books the origin of this term was mentioned to root from the United States. During the presidency of John F. Kennedy, it first appeared in Executive Order 10925 and it was signed by the President on March 6th 1961 (Jain and Ratnam). It was used to refer to methods used to achieve non-discrimination policy implementation. In 1965, Executive Order 11246 was issued by the President Lyndon Johnso n which stated that federal contractors should use affirmative action to avoid discrimination while employing a person. Hiring should be made irrespective of race, religion and national origin. The 1964 Civil Rights Act implemented this clause that no race discrimination by statute should be carried at the workplace. Title II of 1964 act stopped places which were public, such as restaurants or hotels from discriminating on the basis of race. Gradually in 1968, gender was also added to the list. Purpose of Affirmative Action Since the Civil Rights Movement, much has been changed in a positive manner and a great contribution to it was the introduction of Affirmative action. This attempt was to achieve a better and more equal society. It was started as a ‘Corrective measure for societal and governmental discriminations against groups that have been at a disadvantage and subject to prejudices’. However, much has changed since its inception. Supporters of Affirmative Actionà ‚   There are many people, organizations and societies supporting the inherent goodness of affirmative action. Some of them are given below: According to a report published in 2007 by Pew Research Center, support for affirmative action in the American public has increased to 70% in 2007 compared to 58% in 1995. The US Military is another endorser of affirmative action. In 2003, many high ranking officers of Army, Navy, Air force and Marine Corps planned a rally in support of affirmative action for a Supreme Court case Grutter v. Bollinger. The fortune 500 companies have been a popular endorser of affirmative action. More than 60 leading companies in fortune 500 which encompasses 3M, GE, HP, Kraft Foods, Coca-Cola came out for the support of affirmative action in 2003. Universities have been a popular supporter of affirmative action. Harvard University, University of Chicago, University of Pennsylvania, Yale University and Dartmouth College provided their support for race-conscious a dmission programs. They wanted to promote diversity in all forms and, therefore, in 2003 they showed their popular support for it. Popular athletes are endorsers of affirmative action. Many of the Michigan’s leading sports athlete including Tom Izzo (Michigan State University), Joanne P. McCallie (Michigan State University), Tommy Amaker (University of Michigan) and Ernie Zeigler (Central Michigan University) spoke about the importance of affirmative ac

Pre-1914 prose study Essay Example for Free

Pre-1914 prose study Essay It reminds the reader that it is a gothic story. The last story called, The Superstitious Mans Story isnt what is described to be typically gothic, however, and it does include gothic elements. This story isnt typically gothic because it doesnt definitely have murders or doppelgangers; the story just persuades the reader to assume that those things are the solution to the story. This is clear because in the story when the villagers say that they had seen the man, they could have been mistaken. Thomas Hardy only uses one technique in the story which is a simile. The simile is, sleeping as sound as a rock. He uses this simile to show that there was no sign as movement so there is no real proof he was there. In The Red Room, H. G Wells uses the techniques repetition to convince the reader that there is something significant of that room. He uses personification, for example when he describes the shadow to be mocking the characters action so that the reader can imagine that in the room it feels like youre being followed. He uses an effective setting in the red room with dark, daunting colours. Finally he uses metaphors and similes to help the reader picture the room as he describes it. In Confession Found in a Prison, Charles Dickens uses similes and metaphors to emphasise the mans feelings, he used personification to describe his feelings of guilt and regret when he says that the wind that passes whispers murder to him. He also uses an effective setting when he describes the dungeon that the character is present in when he was writing the story. In Thomas Hardys A Superstitious Mans Story, Hardy uses just a simile to prove to the reader that there is a possibility that the man might not have been there because there was no sign that the man was there. In my opinion, I found The red Room the most effective story because the techniques used such as the similes and metaphors really helped me imagine the picture and the scene the story was describing. Also it used many other techniques like the setting described and personification that made me feel suspense and exhilaration whilst reading the story. It also had the best storyline because it had a secret history of murders and deaths that were not exposed; they were just hinted when the old people were warning him of the red room and its effects it has on people. It also has two sides to the story; it has a supernatural side because of the history and noises and shadows that couldnt be explained. The second side is the realistic side when he gets out of the castle and he realises that it wasnt ghosts or spirits in the room that were making him uncomfortable but it was just his mind playing tricks on him.

Free Grapes of Wrath Essays: Steinbecks Style :: Grapes Wrath essays

Analysis of Style of The Grapes Of Wrath  Ã‚  Ã‚     John Steinbeck’s The Grapes Of Wrath is a moving novel, full of richly metaphorical language.   His writing style often evokes deep emotions, as it does in the passage reprinted below, by creating a clear picture in your mind of what he’s trying to say.   In this selection, he enforces a strong image in the reader’s mind: you cannot escape your past, which will be with you no matter where you go or what you do.   This message is enforced through a combination of wit and style in his writing that is rarely found among literary works.       But you can’t start.   Only a baby can start.   You and me—why, we’re all that’s been.   That anger of a moment, the thousand pictures, that’s us.   This land, this red land, is us; and the flood years and the drought years are us.   We can’t start again.   The bitterness we sold to the junk man—he got it all right, but we have it still.   And when the owner man told us to go, that’s us; and when the tractor hit the house, that’s us until we’re dead.   To California or any place—every one a drum major leading a parade of hurts, marching with our bitterness.   And some day—the armies of bitterness will all be going the same way.   And they’ll all walk together and there’ll be a dead terror from it.  Ã‚  Ã‚   (ch. 9, p. 11)    An important point that Steinbeck tries to deliver is the significance of memory.   â€Å"The bitterness we sold to the junk man—he got it all right, but we have it still.†Ã‚   Despite having rid themselves of the physical presence of reminders of past woes, the mental image and pain still remain.   Just because there isn’t anything around to provide evidence of something happening doesn’t mean that it will go away.   â€Å"You and me—why, we’re all that’s been,† he wrote—people are defined by their experiences as memories, not by what is around them.   One’s character is shaped from within, by his mind and his thoughts, not what he surrounds himself with in the external world. Steinbeck’s word choice has a very significant impact on the effectiveness of his writing.   By using words and phrases like â€Å"junk man,† â€Å"dead terror,† and the repetition of the words â€Å"bitterness† and â€Å"dead,† he drives his point home in a very matter-of-fact sort of way.

The destructive results of Insomnia

Insomnia is one of widely-spread sleep disorders which as a result of worries, fears, anxiety and bad brain patterns function make a person unable to maintain his/her sleep. The people suffering from insomnia become irritable the next day and often worry about the coming night when they will have to fight for sleep.As a result during the day people may meet unexpected desire to fall asleep what completely ruins the course of the day and leads to stress and depression. A person with Insomnia may also suffer from other sleep disorder such as sleep apnea, narcolepsy, and restless legs syndrome.The destructive results of Insomnia make us to think of it as a serous mental disease, however it is only a symptom caused by medications, psychological condition, inappropriate sleeping habits or by other stressful events. Among the medications that may greatly contribute to the progression of Insomnia are caffeine, tobacco, alcohol, antidepressants, amphetamines, diuretics, appetite suppressants and different drug products including cocaine and marijuana.The extent to which a person can be imposed to Insomnia has two levels of difficulty. The primary Insomnia defines a person who is having sleep problems are not directly connected with any other health states or problems. Secondary Insomnia means that a person’s inconveniences with sleep are associated with inherent health conditions such as depression, cancer, heartburn, asthma or others. Because of their pain and medications they are taking they start to have other health problems which are connected by the chain of successive conditions.Sleep disorder in its primary level can be easily treated if a person take make a habit from the following activities: ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Regularity of sleep times; ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Comfortable conditions for sleep (bed, temperature and lightening); ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Prevention from accepting the stimulants (e.g. coffee or ciga rettes); ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Practice of relaxation methods; ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Avoidance from taking naps during the day.  Medicines interference into Insomnia treatment is not required as it can be treated with setting new sleeping habits. However for short-term Insomnia one can use over-the-counter sleeping drugs. It is important not to use them regularly as there may appear dependence upon them and create the situation of good sleep impossibility unless the drug is used.Treatment for long term Insomnia requires more complex procedure. First it is needed to conduct a first treating of any underlying conditions or health problems that are determined to cause Insomnia. If Insomnia progresses one can chose either to go through the behavioral therapy or start to accept medications. The first method helps people to replace their ways of living and focus on achieving of specific goals while gaining more control over their lives.Professionals in the fi eld of advancement of Behavior Therapy identify some common goals of behavior therapy. The Insomnia persons should follow this goal which requires for them to use only one bedroom for sleep (Acting), try to understand how his/her stresses influence the sleep (Feeling), to realize that at least 7 hours of sleep is a must for everyone (Thinking), to integrate diet and exercise to encourage the sleep (Dealing), and to train himself/herself in self-management skills (Coping). Medical therapy by contrast with Behavioral therapy has side effects and must be used with caution.Bibliography:1. Fogel J (2003). Behavioral treatments for insomnia in primary care settings.

Dickens present as the perfect gentleman Essay

One of the most important themes in â€Å"Great Expectations† is the idea of what makes the perfect gentleman. Dickens presents this idea through the adventures of Pip and how he develops his idea of what a true gentleman is. His first image of a gentleman is purely based on what their appearance is, such as Cousin Raymond and Jaggers on Miss Havisham’s birthday, and then he calls Herbert â€Å"the pale young gentleman†. These presumptions are not based on personality, yet towards the end of the book, he does not respect Herbert or Magwitch due to their appearance, but because he has realised that a true gentleman has many more qualities than just a good outward appearance. However, Pip’s initial impressions of a gentleman are of a person who is wealthy and affluent. When Pip first meets a gentleman, Cousin Raymond at Satis House on Miss Havisham’s birthday, he describes him and three other ladies as â€Å"toadies and humbugs†. Here, Dickens presents them as very unpleasant characters and makes the reader hate them from the start. This effect is created by how he first presents them as boring (â€Å"the ladies had to speak quite rigidly to repress a yawn†), and then they look down at Pip (â€Å"they all looked at me with the utmost contempt†). Here Dickens seemed to be sending out the message that not all so-called â€Å"gentlemen† are necessarily polite or well-mannered. Furthermore, Pip’s next meeting with a gentleman is not pleasant either. When Pip first meets Jaggers, on the same day, Pip does not take a liking to him either. Dickens presents him as a bossy type of person, suggested by the language which Jaggers uses whilst talking to Pip. He first asks him â€Å"Boy of the neighbourhood? † This implies that Jaggers thinks less of Pip; as inferior to him. This is incredibly rude of Jaggers, who also suggests that he is like an object, by referring to him by a bad â€Å"set† of fellows. Jaggers would definitely be considered a gentleman by the Victorians at that time. As he himself mentions, he is â€Å"pretty well known† and is very wealthy. Here Dickens presents him as a snob who is simply showing off. However, Jaggers would simply not be considered a gentleman in a more modern society as he is definitely not caring or loving or even slightly kind. This is shown by the way in which he only wants a yes or no answer and that when someone doesn’t, he very rudely interrupts and asks them again. For example, when he is talking to his clients, he asks one of them if they have paid Wemmick yet. When that person doesn’t answer yes or no, Jaggers tells them that â€Å"I don’t ask you when you have made it up†¦ Have you paid Wemmick? † This instantly shows the true character of Jaggers as a selfish person who always gets what he wants.

The Pelican Brief Essays

The Pelican Brief Essays The Pelican Brief Paper The Pelican Brief Paper The pelican brief. „The pelican brief† is the 3rd novel written by John Grisham in 1992. Most of his novels are about lawyers and so is this one. I could say that this book is definitely the one with most action in it, because the storyline is based on major government cover-up. One aspect of this book is its theme. The main theme of this novel is large-scale conspiracies in America. The author shows us the dark side of political and economical impact and its importance in the same time. The story starts out with two Supreme Court Justices murdered for no apparent reason. The main character is a young law student, named Darby who gets drawn apart in the deeps of political conspiracies by writing a brief in witch she reveals her theory of conspiracy. It was a shot in the dark for Darby, a brilliant guess, which appeared to be true and that’s the main reason why she becomes a target for a big business and political giant- Victor Mattiece, who murders Darby’s friend Thomas Callahan and Gavin while the young student tries to run to earth the evidence against Victor Matice. Darby have to deal face to face with the political corruption, trying to get evidence against the persons involved in these crimes. Throughout the novel her struggle with guilt and pain is blowing up , as well as her fear. The author shows how hard it is to be alone against all system of bureaucratie. To some this may seem ironic that a young female law student can so easily write a brief, that turns out to be the only document that can cover up such a large-scale corruption, but that is not the point. The idea is to show political system problems in general. In my opinion the author ties to show us that they are more interested in golf than a major government crisis, and choose to let others worry about it. Step by step the young law student and her friend Gray debunks a shifty cover-up, made by the most prestigious men in the country. In the end of the book Darby lies in the beach feeling slightly free from all troubles she have lived thought. The second aspect of â€Å"The Pelican brief† is it’s style . The author’s language is quite pleasant, he writes in the 3rd person. The interest aroused quite quickly, because of the unexpected turn in the very beginning . I could say that it is hard to follow the storyline if you have missed some events, because the story is fast mooving. The final aspect of â€Å"The Pelican brief is its value. The story has an influence on reader it made me think about who you can and cant trust, and also showed some skills of being sharp. I think John Grishams goal while writing this novel was to strike suspense, fear, happiness, and enjoyment into the reader in the same time.

Green Ash Tree Facts, Identification, and Management

Green Ash Tree Facts, Identification, and Management Green ash will reach a height of about 60 feet with a spread of 45 feet. Upright main branches bear twigs which droop toward the ground then bend upward at their tips much like Basswood. The glossy dark green foliage will turn yellow in the fall, but the color is often muted in the south. There is a good seed-set annually on female trees which are used by many birds but some consider the seeds to be messy. This fast-growing tree will adapt to many different landscape conditions and can be grown on wet or dry sites, preferring moist. Some cities have over-planted green ash. Specifics of the Green Ash Scientific name: Fraxinus pennsylvanicaPronunciation: FRACK-sih-nus pen-sill-VAN-ih-kuhCommon name(s): Green AshFamily: OleaceaeUSDA hardiness zones: 3 through 9AOrigin: Native to North AmericaUses: Large parking lot islands; wide tree lawns; recommended for buffer strips around parking lots or for median strip plantings in the highway; reclamation plant; shade tree;Availability: Generally available in many areas within its hardiness range. Native Range Green ash extends from Cape Breton Island and Nova Scotia west to southeastern Alberta; south through central Montana, northeastern Wyoming, to southeastern Texas; and east to northwestern Florida and Georgia. Description Leaf: Opposite, pinnately compound with 7 to 9 serrate leaflets that are lanceolate to elliptical in shape, entire leaf is 6 to 9 inches long, green above and glabrous to silky-pubescent below. Crown uniformity: Symmetrical canopy with a regular (or smooth) outline, and individuals have more or less identical crown forms. Trunk/bark/branches:  Grow mostly upright and will not droop; not particularly showy; should be grown with a single leader; no thorns. Breakage:  Susceptible to breakage either at the crotch due to poor collar formation, or the wood itself is weak and tends to break. Flower and Fruit Flower: Dioecious; light green to purplish, both sexes lacking petals, females occurring in loose panicles, males in tighter clusters, appear after the leaves unfold. Fruit: A single-winged, dry, flattened samara with a slender, thin seed cavity, maturing in autumn and dispersing over winter. Special Uses Green ash wood, because of its strength, hardness, high shock resistance, and excellent bending qualities is used in specialty items such as tool handles and baseball bats but is not as desirable as white ash. It is also a favorite tree used in city and yard landscapes. Several Green Ash Hybrids ‘Marshall Seedless’- some seeds, yellow fall color, fewer insect problems,; ‘Patmore’ - excellent street tree, straight trunk, good yellow fall color, seedless; ‘Summit’ - female, yellow fall color, straight trunk but pruning required to develop strong structure, abundant seeds, and flower galls can be a nuisance; ‘Cimmaron’ is a new plant (USDA hardiness zone 3) reported to have a strong trunk, good lateral branching habit, and tolerance to salt. Damaging Pests Borers: Common on Ash and they can kill trees. The most common borers infesting Ash are Ash borer, lilac borer, and carpenterworm. Ash borer bores into the trunk at or near the soil line causing tree dieback. Anthracnose: also called leaf scorch and leaf spot. Infected parts of the leaves turn brown, especially along the margins. Infected leaves fall prematurely. Rake up and destroy infected leaves. Chemical controls are not practical or economical on large trees. Trees in the south can be severely affected. The Most Widely Distributed   Green ash (Fraxinus pennsylvanica), also called red ash, swamp ash, and water ash  is the most widely distributed of all the American ashes. Naturally a moist bottomland or stream bank tree, it is hardy to climatic extremes and has been widely planted in the Plains States and Canada. The commercial supply is mostly in the South. Green ash is similar in property to white ash and they are marketed together as white ash. The large seed crops provide food to many kinds of wildlife. Due to its good form and resistance to insects and disease, it is a very popular ornamental tree.

Interactions of hazardous materials Essay Example | Topics and Well Written Essays - 500 words

Interactions of hazardous materials - Essay Example According to the given incident, the ‘class 8’ label on the tanker shows that the liquid is corrosive (like sulphuric acid, hydrochloric acid, Sodium hydroxide or potassium hydroxide). The NFPA diamond with a 0 at 12 o'clock, shows that the liquid will not catch fire, a 2 at 3 o'clock shows that the liquid will undergo violent chemical change under normal conditions, a 4 at 9 o'clock shows that the liquid is deadly and it should not be inhaled or allowed to touch a body part under any condition. A slashed W at 6 o'clock depicts that the no water should be allowed to make contact with the chemical under any condition. The chemical will behave violently in contact with water. thus, it is clear from the label that the dripping liquid will nor catch fire but there is a need to maintain a distance between the dripping liquid, as the dripping liquid is vaporizing at normal temperature and pressure and may penetrate into the body through nasal passages and may harm the internal organs like lungs and throat (â€Å"NFPA Labeling Guide†). After viewing the labels and information available on the truck, it is quite clear that the chemical is lethal and probably has an acidic nature. The UN number 1836 identifies that the chemical is ‘Thionyl Chloride’, which is harsh chemical and reacts vigorously in contact with water and alkaline chemicals.
