Answer to Common Hot Ice Questions

Answer to Common Hot Ice Questions Several of you have written in asking for help with your homemade hot ice or sodium acetate. Here are the answers to the most common hot ice questions as well as advice on how to fix the usual problems making hot ice. What Is hot ice? Hot ice is a common name for sodium acetate trihydrate. How Do I Make Hot Ice? You can make hot ice yourself from baking soda and clear vinegar. Ive got written instructions and a video tutorial to show you how to do it. In the lab, you could make hot ice from sodium bicarbonate and weak acetic acid (1 L 6% acetic acid, 84 grams sodium bicarbonate) or from acetic acid and sodium hydroxide (dangerous! 60 ml water, 60 ml glacial acetic acid, 40 g sodium hydroxide). The mixture is boiled down and prepared the same as the homemade version. You can also buy sodium acetate (or sodium acetate anhydrous) and sodium acetate trihydrate. Sodium acetate trihydrate can be melted and used as-is. Convert sodium acetate anhydrous to sodium acetate trihydrate by dissolving it in water and cooking it down to remove the excess water. Can I Substitute Baking Powder for the Baking Soda? No. Baking powder contains other chemicals which would act as impurities in this procedure and prevent the hot ice from working. Can I Use Another Type of Vinegar? No. There are impurities in other types of vinegar which would prevent the hot ice from crystallizing. You could use dilute acetic acid instead of vinegar. I Cant Get the Hot Ice to Solidify. What Can I Do? You dont have to start from scratch! Take your failed hot ice solution (wont solidify or else is mushy) and add some vinegar to it. Heat the hot ice solution until the crystal skin forms, immediately remove it from heat, cool it at least down to room temperature, and initiate crystallization by adding a small quantity of the crystals that formed on the side of your pan (sodium acetate anhydrous). Another way to initiate crystallization is to add a small amount of baking soda, but if you do that you will contaminate your hot ice with sodium bicarbonate. Its still a handy way to cause crystallization if you dont have any sodium acetate crystals handy, plus you can remedy the contamination by adding a small volume of vinegar afterward. Can I Re-Use the Hot Ice? Yes, you can re-use hot ice. You can melt it on the stove to use it again or you can microwave the hot ice. Can I Eat Hot Ice? Technically you can, but I wouldnt recommend it. It is not toxic, but it is not edible. You Show Glass and Metal Containers. Can I Use Plastic? Yes, you can. I used metal and glass because I melted the hot ice on the stove. You could melt the hot ice in a microwave using a plastic container. Are Containers Used to Make Hot Ice Safe to Use for Food? Yes. Wash the containers and they will be perfectly safe to use for food. My Hot Ice Is Yellow or Brown. How Do I Get Clear/White Hot Ice? Yellow or brown hot ice works... it just doesnt look that much like ice. The discoloration has two causes. One is overheating your hot ice solution. You can prevent this type of discoloration by lowering the temperature when you heated the hot ice to remove the excess water. The other cause of discoloration is the presence of impurities. Improving the quality of your baking soda (sodium bicarbonate) and acetic acid (from the vinegar) will help prevent discoloration. I made my hot ice using the least expensive baking soda and vinegar I could buy and managed to get white hot ice, but only after I lowered my heating temperature, so its possible to get decent purity with kitchen ingredients.

16 Misquoted Quotations

16 Misquoted Quotations 16 Misquoted Quotations 16 Misquoted Quotations By Mark Nichol Many quotations attributed to famous people are at best paraphrases though often superior to the original. Others might be subtly altered in the retelling, sometimes with little impact on their effect, at other times irresponsibly changing the meaning. Here is a selection of well-known sayings or writings that aren’t quite accurate (followed by a couple that are but are mistakenly identified as erroneous): 1. â€Å"Be the change you wish to see in the world.† This quotation attributed to Gandhi is a later invention by an unknown person, likely inspired by the following passage: â€Å"As a man changes his own nature, so does the attitude of the world change towards him. . . . We need not wait to see what others do.† 2. â€Å"First they ignore you. Then they laugh at you. Then they attack you. Then you win.† Gandhi was also credited with this pithy progression, but something like it was actually uttered in a speech at a union meeting in the United States in 1914: â€Å"First they ignore you. Then they ridicule you. And then they attack you and want to burn you. And then they build monuments to you.† 3. â€Å"Hell hath no fury like a woman scorned.† This is an amended version of a line by playwright William Congreve, who flourished around the turn of the eighteenth century. The actual comment is â€Å"Heaven has no rage like love to hatred turned / Nor hell a fury like a woman scorned.† 4. â€Å"I disapprove of what you say, but I will defend to the death your right to say it.† As with many of these lines, the person to whom it is attributed in this case, Voltaire, perhaps would have wished he had been so eloquent. This ringing pronouncement, however, derives not from the French philosopher’s own pen, but from an early-twentieth-century biography of him. 5. â€Å"Methinks the lady doth protest too much.† This is a slightly recast alteration of Queen Gertrude’s response to Hamlet’s query about how his mother likes the play he has, unbeknownst to her, scripted to prompt a guilty reaction from her and King Claudius, who Hamlet believes conspired to murder his father. She is saying that the character of the queen is trying too hard to appear innocent. The original, no better or worse merely measured differently is â€Å"The lady doth protest too much, methinks.† 6. â€Å"Money is the root of all evil.† This alteration of a biblical verse, by omitting a vital element of the original, changes the meaning significantly. The verse actually reads, â€Å"For the love of money is the root of all evil.† 7. â€Å"Power corrupts; absolute power corrupts absolutely.† This misquotation lacks the equivocation of British historian Lord Action’s actual statement, â€Å"Power tends to corrupt; absolute power corrupts absolutely† and omits the blunt next sentence: â€Å"Great men are almost always bad men.† 8. â€Å"Music hath charms to soothe the savage beast.† The actual quote, from the same play from which the line in the third entry above is taken, is â€Å"Music hath charms to soothe a savage breast.† The next line, elaborating on the theme, is â€Å"To soften Rocks, or bend a knotted Oak.† 9. â€Å"Nice guys finish last.† Legendary baseball manager Leo Durocher wasn’t making a blanket statement when he uttered these four words. They are a contracted repetition of his assessment of a baseball team’s prospects for the season. The entire quotation is â€Å"All nice guys. They’ll finish last. Nice guys finish last.† 10. â€Å"No rest for the wicked.† This line, uttered jocularly by a busy person, perhaps as an excuse for departing, is probably inspired by the biblical verse â€Å"There is no peace, saith my God, to the wicked.† 11. â€Å"Now is the winter of our discontent.† These first few words of Shakespeare’s Richard III are often expressed to mean â€Å"The present time is the winter of our discontent.† What the titular character means, however, is made clear by including the second part of the statement, which demonstrates that the phrase is merely a preface to the counterpoint of a reference to better times: â€Å"Now is the winter of our discontent / Made glorious summer by this sun of York.† 12. â€Å"Pride comes before a fall.† This is a contracted version of the biblical verse â€Å"Pride goeth before destruction, and an haughty spirit before a fall.† 13. â€Å"Reports of my death have been greatly exaggerated.† Mark Twain’s actual comment is more straightforward: â€Å"The report of my death is an exaggeration.† In addition, the statement is in reference not to a prematurely printed obituary but to a reporter’s inquiry about his health. 14. â€Å"The only thing necessary for the triumph of evil is for good men to do nothing.† This quotation is a vast improvement over this vaguely similar statement by Irish-born British statesman Edmund Burke: â€Å"When bad men combine, the good must associate; else they will fall one by one, an unpitied sacrifice in a contemptible struggle.† 15. â€Å"Theirs but to do or die.† The legendary phrase from Alfred, Lord Tennyson’s â€Å"The Charge Of The Light Brigade† has a subtly but significantly different penultimate word. The entire line reads, â€Å"Theirs not to reason why / Theirs but to do and die.† 16. â€Å"Water, water everywhere, and not a drop to drink.† The line from Samuel Taylor Coleridge’s â€Å"Rime of the Ancient Mariner† has been tidied up a bit. The original is â€Å"Water, water, every where, / Nor any drop to drink.† Two other well-known statements considered to be misquotes are actually later versions of lesser-known comments. Winston Churchill’s phrase â€Å"Blood, sweat, and tears,† widely believed to be an erroneous version of â€Å"I have nothing to offer but blood, toil, tears, and sweat,† is actually a more concise and euphonious update of the more extended form. By the same token, â€Å"I laughed all the way to the bank† is an alleged misquotation (and misunderstanding of Liberace’s quip â€Å"I cried all the way to the bank,† but he actually did use laughed in response to a poor review of a financially successful concert of his. When he later won a lawsuit with compensation stemming from a newspaper’s veiled contention that he was gay (the nerve!), he altered the earlier utterance with a change of verb to reply to a query about whether the accusation made him distraught.

The Olmec Royal Compound at La Venta

The Olmec Royal Compound at La Venta The Olmec Royal Compound at La Venta: La Venta was a great Olmec city which thrived in the present-day Mexican State of Tabasco from around 1000 to 400 B.C. The city was built on a ridge, and on top of that ridge are several important buildings and complexes. Taken together, these make up the â€Å"Royal Compound† of La Venta, an extremely important ceremonial site. The Olmec Civilization: The Olmec culture is the earliest of the great Mesoamerican civilizations and is considered by many to be the mother culture of later peoples such as the Maya and the Aztecs. The Olmecs are associated with several archaeological sites, but two of their cities are considered more important than the others: San Lorenzo and La Venta. Both of these city names are modern, as the original names of these cities have been lost. The Olmecs had a complex cosmos and religion.a including a pantheon of several gods. They also had long-distance trade routes and were extremely talented artists and sculptors. With the fall of La Venta around 400 B.C. the Olmec culture collapsed, succeeded by the epi-Olmec. La Venta: La Venta was the greatest city of its day. Although there were other cultures in Mesoamerica at the time La Venta was at its apex, no other city could compare in size, influence or grandeur. A powerful ruling class could command thousands of workers for public works tasks, such as bringing huge blocks of stone many miles to be carved at Olmec workshops in the city. Priests managed the communications between this world and the supernatural planes of the gods and many thousands of common people labored in the farms and rivers to feed the growing empire. At its height, La Venta was home to thousands of people and directly controlled an area of around 200 hectares – its influence reached much further. The Great Pyramid – Complex C: La Venta is dominated by Complex C, also called the Great Pyramid. Complex C is a conical construction, made of clay, which was once a more clearly defined pyramid. It stands about 30 meters (100 feet) high and has a diameter of about 120 meters (400 feet) It is man-made of nearly 100,000 cubic meters (3.5 million cubic feet) of earth, which must have taken thousands of man-hours to accomplish, and it is the highest point of La Venta. Unfortunately, part of the top of the mound was destroyed by nearby oil operations in the 1960’s. The Olmec considered mountains sacred, and since there are no mountains nearby, it is thought by some researchers that Complex C was created to stand-in for a sacred mountain in religious ceremonies. Four stelae located at the base of the mound, with â€Å"mountain faces† on them, seem to bear out this theory (Grove). Complex A: Complex A, located at the base of the Great Pyramid to the north, is one of the most important Olmec sites ever discovered. Complex A was a religious and ceremonial complex and served as a royal necropolis as well. Complex A is home to a series of small mounds and walls, but it is what is underground that is most interesting. Five massive offerings have been found in Complex A: these are large pits which were dug out and then filled with stones, colored clay and mosaics. Many smaller offerings have been found as well, including figurines, celts, masks, jewelry and other Olmec treasures given to the gods. Five tombs have been found in the complex, and although the bodies of the occupants decomposed long ago, important objects have been found there. To the north, Complex A was guarded by three colossal heads, and several sculptures and stelae of note have been found in the complex. Complex B: To the south of the Great Pyramid, Complex B is a large plaza (referred to as Plaza B) and a series of four smaller mounds. This airy, open area was most likely a place for the Olmec people to gather to witness ceremonies that took place on or near the pyramid. Several noteworthy sculptures were found in Complex B, including a colossal head and three Olmec-style sculpted thrones. The Stirling Acropolis: The Stirling Acropolis is a massive earthen platform which dominates the eastern side of Complex B. On top are two small, circular mounds and two long, parallel mounds that some believe may be an early ballcourt. Many fragments of broken statues and monuments as well as a drainage system and basalt columns have been found in the acropolis, leading to speculation that it may have once been the royal palace where the ruler of La Venta and his family resided. It is named for American archaeologist Matthew Stirling (1896-1975) who did a great deal of important work at La Venta. Importance of the La Venta Royal Compound: The Royal Compound of La Venta is the most important section of one of the four most important Olmec sites located and excavated to date. The discoveries made there - in particular at Complex A - have changed the way we see the Ancient Olmec culture. The Olmec civilization, in turn, is very important to the study of Mesoamerican cultures. The Olmec civilization is important in that it developed independently: in the region, there are no major cultures that came before them to influence their religion, culture, etc. Societies like the Olmec, which developed on their own, are referred to as pristine civilizations and there are very few of them. There may yet be even more discoveries to make in the royal compound. Magnetometer readings of Complex C indicate there is something in there, but it has not yet been excavated. Other digs in the area may reveal more sculptures or offerings. The royal compound may yet have secrets to divulge. Sources: Coe, Michael D and Rex Koontz.

Save students money - Assignment Example The author believes that such a change, if brought about would be potentially disastrous as it would lead to printed textbooks becoming obsolete. In my opinion, such a change is unfavorable for students as using e-books would be inconvenient for them and for some, would be more expensive then purchasing textbooks. The proponents of introduction of e-books as required reading in colleges and universities include the college officials and some important textbook companies such as McGraw Hill and John Wiley and sons, amongst others, as Jeffrey Young points out in this article. These parties propose including a fixed mandatory fee per course in the tuition fee for providing the e-books to the students. Some of the colleges such the Daytona State College have already adopted this change while others like Indiana University are still in the experimental phase. The college officials believe that e-books would be cheaper for the students, if they are purchased in bulk by the college and prov ided to the students at a subsidized rate. Moreover, the publishing industry believes that such a change would help in reducing the rates of digital piracy. Thus, such a collaboration is thought to benefit all parties, viz. the students, the colleges and the publishing companies.

Data Security - Essay Example In case, the server is online, it transmits that signal straight back to the computer, letting us enjoy secure communications. Both the computer and the server send out heartbeats during regular intervals to ensure that both the user and the server i.e. the service aren’t offline (Kerner 2014). Heartbleed exploits this â€Å"heartbeat† by sending out, a kind of heartbeat signal to servers that is malicious in nature. That malicious heartbeat more or less tricks the server into sending a random amount of its memory to the user who sent the malicious heartbeat. A random collection of email addresses, usernames and passwords can be enclosed in that memory. Some of those records troublingly, could belong to the company running that server. This affords hackers with a method of infiltrating and exploiting information across the Internet. The Shellshock issue is a sample of ACE (arbitrary code execution) vulnerability. Classically, ACE vulnerability attacks are carried out on running programs and entail an extremely advanced understanding of the internals of assembly language, code execution and memory layout—the kind of attack that calls for an expert, to be concise (Sampathkumar, Balasubramani 2014). The attacker employed an ACE vulnerability to run a program granting them an easy way of dominating the targeted machine. This is accomplished by means of running a "shell". A shell is a command-line where commands can be executed or entered. The Shellshock vulnerability is a big concern since it eliminates the necessity for specialized knowledge and in turn offers a simple (unfortunately, very basic) means of taking control of another computer or even a web server to make it run code. The attack seemingly looked to have been triggered by a malicious computer code referred to as malware, according to people familiar with such matters. Some people suggested, a probable Russian or

Industrial hazards include fire and explosion, biologic hazards, ionizing radiation, heat stress, chemical exposure, electrical hazards, oxygen deficiency, noise, safety hazards, and cold exposure. These hazards among other incidents or situations in the contemporary industrial sector require the skill of an industrial hygienist. Furthermore, events such as the anthrax scares, terrorist attacks, and the potential use of â€Å"dirty bombs† enhance the importance for the awareness on the principles of industrial hygiene. The framework or main principles of industrial hygiene and toxicology include recognition, anticipation, control, and evaluation of workplace hazards. As such, an industrial hygienist must take into consideration these principles to ensure safety and health in the workplace. This paper will discuss ionizing radiation, a physical agent in industria l work environment. It will also discuss its effects on exposure, control, principles, and regulations. Ionizing radiation constitutes particles that hold sufficient energy to free an electron from a molecule or atom, thus ionizing it. This radiation is produced through nuclear reactions, natural or artificial, and by extremely high temperature. Ionizing radiation is also generated through high-energy particle production using particle accelerators, nuclear decay, or charged particles acceleration through electromagnetic fields created by innate processes such as supernova explosions and lighting (Wilson para.10). As such, natural sources of ionizing radiation include the supernova explosions, lightning, the sun, and artificial sources that include x-ray tubes, particle accelerators and nuclear reactors. Ionizing radiations includes x-rays, gamma, beta, alpha, and cosmic rays. There are three harmful radiation emitted by radioactive materials, which

Non-Sovereign small islands in the international economy Essay

Non-Sovereign small islands in the international economy - Essay Example Generally speaking, the OFCs were accused in undermining the stability and inviolability of the global financial system. To manage the situation, a group of initiatives were taken by the Financial Stability Forum, the International Monetary Fund, the Organisation for Economic Co-operation and Development (OECD), the European Union and the Financial Action Task Force (Woodward 686). In addition to the development of small islands as offshore financial centres, there are some other examples of cases when many small islands have exceeded in small-scale, high-value service and product-niching in various fields of economic activities, including: finance and banking, brokerage, tourism and hospitality (Baldacchino 254). This paper is focused on the research the small islands, performing an important role in the international economy and on the global arena. The more detailed analysis is carried out for the British Isle’s Crown dependencies: the Isle of Man, and the Channel Islands o f Jersey and Guernsey, as well the Prince Edward Island. The Financial Services Sector: the Isle of man, the Channel Islands and New "Havens"Among Developing Small Islands There are many various definitions of the offshore, which is the evidence of the challenges which many scholars and economists face in attempt to explain this concept precisely. For example, Palan defines the offshore as a â€Å"special territorial or juridical enclave†, in which regulation or taxation in the state is either partially or fully withheld (cited by Payne 627-628). While significant stress in the definition of the offshore falls on the territorial dimension, juridical properties is what really matters. Richard Woodward clarifies this view by the statement: â€Å"offshore is a legal as well as physical domain; where an activity takes place is secondary to the rules under which it takes place† (cited by Payne 628). Even though there are some slight variations in definitions, offshore finan cial centres have a set of common characteristics. The offshore financial centers can be characterized by the following attributes: minimal taxes or tax free; bank anonymity and secrecy laws at a high level, a high number of financial institutions, which serve mainly non-residents; flexibility of use of various company structures, the proportions of financial systems are exceeding needs of the domestic economy, light financial regulation (Levin 2), protection of the secrecy of transactions and few or no restrictions of financial transactions (Palan 155). The most successful OFCs are characterized also by stable economic and political climate, support from of a large international financial market, money laundering or drug money scandals free, availability of agreements for avoiding double-taxation with major countries, and are easily reached due to established information-exchange facilities (Palan 156). Referring back to the last item, many OFCs are developing laws and investing in telecommunications for attracting e-commerce providers (Levin 5). Obviously, telecommunications and IT is a very important factor that enables OFCs to respond to the needs of their customers and operatively react to external changes. Financial centres can be distinguished by many different ways. Thus, for example, International Monetary Fund (n.p.) has developed its own way of differentiation of the financial centers by splitting those into three categories: 1. International financial centres (IFCs) – are large internation
