Sulfur Hexafluoride, the Anti-Helium

Sulfur Hexafluoride, the Anti-Helium Sulfur hexafluoride is a non-toxic, invisible gas that you can use to perform interesting chemistry demonstrations. Breathe it in and make your voice much deeper when you talk. Pour it into a container and float an airplane or a ship on nothing. In a way, it is like the anti-helium gas, because while helium is about six times lighter than air, sulfur hexafluoride is six times heavier. Sulfur Hexafluoride Facts Inorganic compound with a chemical formula SF6Non-polar gasNon-toxic, odorless, colorlessnNn-flammable at room temperature and pressureOctahedral geometryPoorly soluble in water; soluble in nonpolar organic solventsDensity of 6.13 g/L at sea level Fun Things to Try with Sulfur Hexafluoride Float Your Boat: Pour sulfur hexafluoride into an aquarium or large beaker. It is heavier than air, so it will sink. You can float light objects on the invisible gas, such as a paper airplane or a boat made from aluminum foil. If you use a cup to scoop up some of the sulfur hexafluoride and dump it into a foil boat, you can sink it.Talk or Sing with a Deep Voice: Sulfur hexafluoride is denser than air, so sound travels through it more slowly. If you breathe in a lungful of sulfur hexafluoride, your voice will become much deeper. Even though sulfur hexafluoride is non-toxic, you need to use care when performing this demonstration to avoid hypoxia and fainting (the same caution applies to helium). Dont breathe the gas for prolonged periods of time. Where You Can Get Sulfur Hexafluoride Sulfur hexafluoride is a specialty gas, used in medicine for eye surgery and ultrasound imaging; in industry as a tracer gas, dielectric, and as an etchant; and mixed with argon as an insulator between layers of windows.

The first sale doctrine Essay Example | Topics and Well Written Essays - 1250 words

The first sale doctrine - Essay Example Moreover, FSD serves to promote public access to information and culture since it functions as a vital limit on the copyright owner’s right to control the disposition of a work that is copyrighted. People can easily share digital copyrighted works. The FSD preserves and makes available works which are off the market; this is especially amplified within the library context. It also keeps prices low. When publishers realize that they are no longer economically beneficial to keep on producing particular works, the publication of those works will cease. Without the FSD, preservation as well as circulation of those works would also come to an end. Nonetheless, with thrift shops, museums, libraries along with other 3rd parties able to purchase, sell, store and have possession of these works, they are preserved for posterity (Frankel & Harvey, 2011). With this principle and the digitization of media, content has become more available to the public. FSD basically serves to provide a m eans for works to remain in circulation after they are no longer printed, or after the owner of the copyright has withdrawn them from the marketplace. This is a particularly vital function for institutions such as libraries. In the digital marketplace, these benefits are experienced to a considerably large extent. For instance, a book in digital form and copied page by page could be easily reproduced and accessed at one time and easily by everyone. Such physical copies cannot be easily copied in real space. The FSD has allowed buyers of copyrighted materials such as ebooks, music/film DVDs, CDs to resell or utilize the work in several ways with no permission from the holder of the copyright and has made things such as eBay and video rental stores legal (Perzanowski & Schultz, 2010). Question 8: To what extent does the online market today provide opportunities to engage in actions made possible by the first sale doctrine in the analog world, such as sharing favorite books with friend s, or enabling the availability of less-than-full-price versions to students? The marketplace presently does not provide such opportunities primarily because of license terms. The doctrine was established during a period of permanent physical reproductions of books, and the doctrine might be losing its relevance in today’s digital age (Small & Roberts, 2012). In the current era characterized by licenses, people are more and more acquiring films, music and software through downloads which incorporate license terms. This has prevented people from owning copies; rather, they are simply licensees and have no right to re-sell. The FSD was meant to protect purchasers of copies of works that are copyrighted who want to resell their copies by preventing copyright holders from asserting that such re-sales breach their exclusive right of distributing and selling reproductions of the works. Consequently, FSD led to a robust rental and re-sale market for music CDs, films, video games, bo oks among other copyrighted materials with the exception of software (McSherry, 2012). Nonetheless, with the advent of the digital age, FSD presented challenges to some holders of copyright who want to control the re-sale market for their works. FSD is only applicable after the sale of the copyrighted mater

Religious Opposition To Modern States Essay Example | Topics and Well Written Essays - 2000 words

Religious Opposition To Modern States - Essay Example Several deadly terrorist attacks by radical Islamic fundamentalists have targeted American citizens and interests. But the hatred reached a new intensity with the Sept. 11 attacks on the World Trade Center and the Pentagon, killing nearly 5,000 people and demolishing global symbols of American economic might. Now, even as the United States and its allies seek to destroy Osama bin Laden's terrorist network, critics are questioning America's sensitivity to the concerns of the Islamic world and beyond. In his article, Juergensmeyer continued to cite about how politics have come to become inclined to subsume religious issues:Insofar as the US public and its leaders embraced the image of war following the September 11 attacks, the US view of the war was also prone to religionization. "God Bless America" became the country's unofficial national anthem. US President George Bush spoke of defending America's "righteous cause" and of the "absolute evil" of its enemies. However, the US military engagement in the months following September 11 was primarily a secular commitment to a definable goal and largely restricted to objectives in which civil liberties and moral rules of engagement still applied.   In purely religious battles waged in divine time and with heavenly rewards, there is no need to compromise goals. There is also no need to contend with society's laws and limitations when one is obeying a higher authority. In spiritualizing violence, religion gives the act of violence remarkable power.
