Canned Air Isnt Air (Chemical Composition)

Canned Air Isnt Air (Chemical Composition) Canned air isnt air, though it is canned. Its not even filled with a gas you normally find in air. Canned air or gas duster is a product that uses compressed gas to clean surfaces. Its nice for blasting out keyboard chow and dust bunnies in the cooling vents of computers and other electronic devices. You may have heard about people dying from purposely inhaling canned air, presumably trying to get high off of it. There are two ways you can die from this practice. One is from anoxia or simply not getting enough oxygen. The other is from the toxicity of the gases used in the product. The usual gases found in canned air are difluoroethane, trifluoroethane, tetrafluoroethane, or butane. Butane is an interesting choice because its flammable, so using canned air to cool hot electronics may not be a wise decision (see my burning bubbles project if you need convincing about potential flammability). Incidentally, burning the fluorocarbons tends to produce extra-nasty chemicals such as hydrofluoric acid and carbonyl fluoride. My laptop would suffocate and overheat without a little help from canned air every now and then. Its a useful product to have around. Just dont go thinking its a harmless household chemical, because its not.

Word Choice Which vs. Witch - Proofeds Writing Tips

Word Choice Which vs. Witch - Proofeds Writing Tips Word Choice: Which vs. Witch There are up to a million words in the English language. We probably shouldn’t be surprised, then, that some of these words sound similar to one another, such as â€Å"which† and â€Å"witch.† But although â€Å"which† and â€Å"witch† sound alike, they have very different meanings. So to avoid errors in your written work, check out our guide below on how they should be used! Which (Relative Pronoun and Asking Questions) In American English, â€Å"which† is mainly used when introducing a non-restrictive relative clause. This is a clause given after a comma to add extra information about something. For example: I’m going to the see the movie, which my brother directed. Here, â€Å"which† introduces a clause that provides extra information about the movie (i.e., that my brother directed it). Be careful only to use â€Å"which† with non-restrictive clauses, as â€Å"that† is typically used for restrictive clauses (i.e., clauses that help identify something) in American English. Another use of â€Å"which† is to ask questions. In particular, we use it to ask for information that specifies one or more people or things from a group or collection. For instance: Which movie are you going to see today? In this case, we’re asking which among all of the movies currently showing someone is going to see. Witch (Woman with Magic Powers) Traditionally, a â€Å"witch† was a woman thought to have magic powers. The standard image we have of a witch these days, for instance, is an evil old woman with a pointy hat and a broomstick: My daughter dressed up as a witch for trick-or-treating last year. Most people don’t believe in â€Å"evil† witches anymore. However, there are some who follow the Wicca religion who refer to themselves as â€Å"witches.† They don’t all wear pointy hats, though. Please refrain from Salem-like panic if there is a Wiccan in your neighborhood. Which or Witch? These words are very different in practice, so it is important not to mix them up! One way to tell them apart is to think of â€Å"which† as a question word. This can help because it starts with â€Å"wh-,† just like other words we use to ask questions, such as â€Å"what,† â€Å"why† and â€Å"where.† Even if you are introducing a relative clause, this technique can still remind you which word is correct. â€Å"Witch,† meanwhile, typically refers to a female magic user. Remember: Which = Relative pronoun or asking questions Witch = Woman with magic powers

UK Smoking legislation Essay Example | Topics and Well Written Essays - 1000 words

UK Smoking legislation - Essay Example However, the practice is allowed in a private house. If and when individuals contravene the specifications of this legislation, they can be fined  £50-1000. The persons who occupy or are responsible for the management of a smoking free zone have a duty to ensure that there are no-smoking signs in positions which are visible to all visitors, employees and customers. The sign must be size A5 or larger. The correct wording on the signage should be: â€Å"No Smoking. It is against the law to smoke in these premises† (Hughes and Ferrett, 2009). The words â€Å"these premises† can be replaced by the specific name of the premises, such as â€Å"this hotel†. Another obligation is for the public transport which includes trains, taxis and buses, as well as business vehicles which carry more than one employee to display a smoking prohibition sign that has to be at least 70 mm in diameter. The sign must appear in every compartment that is designated for passengers (Great Britain Health Committee, 2005). There are some considerations (Hughes and Ferrett, 2009) that smoke free premises should look into: Tower Hamlets has a high rate of poor health and low life expectancy as compared to other parts of the country. Smoking happens to be the single biggest cause of death among the borough’s residents. Smoking is the reason for the wide gap in life expectancy between Tower Hamlets and the rest of UK. At least one person dies in the borough due to smoking. The London Borough of Tower Hamlet council supports the no-smoking policy. The council has innovated a scheme that is aimed at creating a healthier society, protected from the effects of second hand smoke. In 2009, the council, under the Tobacco Control Alliance umbrella, introduced the Smokefree Business Award as a step to enforce the smoke ban introduced in the country in 2007 (Tower Hamlets Council, 2010). The program involves ensuring

Why I wish to become an osteopathic physician and why I think Ohio Essay

Why I wish to become an osteopathic physician and why I think Ohio University College of Osteopathic Medicine is a good choice f - Essay Example However, it is my conviction that an osteopathic physician is a bit different if not way apart from an allopathic physician in the sense that osteopathy is a more pragmatic, realistic and hands on approach towards physical maladies. Administering medicine or surgery does have their importance and relevance in the curing of disease, but more important and practical in any therapeutic approach is to exploit the body’s innate capacity to heal and cure itself. Human body inevitably has a quintessential and undeniable mechanical aspect associated with it and the body’s structures and functions are intimately related to each other. So, being an osteopathic physician offers to me the best of both worlds. To begin with, it allows me to approach a patient’s malady with a more noninvasive approach, using her and if required, aiding her intrinsic healing ability through osteopathic manipulation and approach. At the same time, it extends to me the confidence and reassurance that if the things get drastic and require a more imminent line of therapy, I can always resort to the allopathic and surgical aspects of my training to gain control. Osteopathy is an approach towards healing that is perfectly in consonance with my personal philosophy and beliefs about illness and healing.

Stanleys Control in A Streetcar Named Desire Essay -- Control A Stree

Stanley's Control in A Streetcar Named Desire Remember what Huey Long said – Every Man is a King! - Explain how Stanley had his control, how he has had his kingship challenged and how he is trying to re-establish his control. â€Å"Remember what Huey Long said – â€Å"Every Man is a King!† Explain how Stanley had his control, how he has had his kingship challenged and how he is trying to re-establish his control. In the opening of â€Å"A Street Car Named Desire† by Tennessee Williams, we are presented with a stereotypical presentation of a husband and wife. However, during the duration of the play, we see how Stanley changes from being in control, to loosing his control and using desperate measures to regain a higher status. In Scene 1 the impression the audience gets about Stanley is that he is in control over his wife. The first time the audience sees him, he â€Å"bellows† at Stella and Stella â€Å"mildly† talks back to him, showing Stanley’s higher status. Stanley also â€Å"hurls† a meaty package at Stella, showing his masculine power that he possesses. Stella, in contrast, is the one that waits for Stanley. The first time we see Stella and Stanley together, Stanley has gone to find Stella rather than the other way round. This gives the audience the impression that Stella is almost a stay at home wife to Stanley. When Blanche and Stanley first meet, it is easy to see that Stanley feels as if he has control. He â€Å"starts to remove his shirt† in front of Blanche when he has first met her, indicating his confidence and his high status attitude. A small indication that Stanley’s â€Å"kingship† is being challenged is show in the start of Scene 2. In Scene 2, Stella takes Blanche out to a show and supper, while Stanley has ... ... then chooses Stanley, leaving Blanche to be taken away by a Doctor to a mental hospital. In the beginning of the play it is clear to see how Stanley has higher status than Stella, shown through a combination of stage directions and speech. Stanley realises that his status has been lost fairly early on in the play, and firstly believes that he must show his masculine power by hitting Stella. This is obviously the way he has solved any previous issues to do with his masculinity, as Stella says about how â€Å"Stanley’s always smashed things†. Stanley realises how this usual solution won’t work this time, so he puts his efforts into driving Blanche away. He succeeds in doing this, but it shows the audience a terrible side to Stanley. His last action to regain masculinity is an awful act with risky consequences, as Stella could have easily turned against him.

The Portrayal of Lady Brett Ashley as the Modern Woman of...

Women of the 1920’s compared to women today are seen as very passive and were usually domestic wives whose main responsibility was to take care of the house and children. But throughout this decade, women were starting to slowly modernize and become more independent. In The Sun Also Rises by Ernest Hemingway, Lady Brett Ashley is somewhat portrayed as â€Å"the admirable new woman† of the 1920’s-the woman who openly flaunts accepted conventions of the passive, dependent female role in society and emerges as a positive, inspiring, and risk-taking figure in Paris, Pamplona, and Madrid among the male expatriate artists. In the novel, we see Brett as a modern and somewhat inspiring woman through characterization and the analysis of specific moments†¦show more content†¦This is admirable and inspiring because it gives a role model to other women during these years. There were probably many women who felt bored with their life in the shadow and who wanted to l ive the same life as Brett but were too afraid of other people’s reactions. But although Brett may have set a role model for other women, she still had her flaws, one of them being that she was very promiscuous and had several affairs, leading men on to think that she cared for them, for so to ditch them for someone else. One very good example of this is her relationship with Jake. She cared deeply for Jake, but kept on hurting him, not necessarily intentionally, by her not wanting to be in a relationship with him due to his impotents. After Jake and Brett depart in Pamplona, Jake goes to San Sebastian, but quickly after his arrival, he receives a telegram from Brett who was in trouble, and needed Jakes help. The telegram said: â€Å"Can you come to hotel Montana Madrid, am rather in trouble, Brett† (Hemingway 209). The reason Brett is contacting Jake to help her is because she has decided to leave Romero, her 19 year old lover whom she left to Madrid wit. Brett knows how strongly Jake feels about her, and knows that he will always be there for her wh en she is in trouble, something that is proven when Jake says: â€Å"Well, that means San Sebastian all shot to hell. I suppose, vaguely, I had expected something of
