The Facts About Dry Ice

Dry ice is the solid form of solid carbon dioxide, CO2. Some of the following facts about dry ice that will help keep you safe when working with it—and others are just fun to know. Dry Ice Facts Dry ice, sometimes called cardice, is solid carbon dioxide.Dry ice is extremely cold (-109.3 °F or -78.5 °C). At this temperature, dry ice sublimates from a solid state into a gaseous state or undergoes deposition from gas to solid. Dry ice must be placed in a high-pressure environment in order to form liquid carbon dioxide.The first published observation of dry ice was in 1835 by French chemist Charles Thilorier, who noted the formation of dry ice when a container of liquid carbon dioxide was opened.Dry ice resembles snow or water ice.  Its usually sold as chunks or pellets, which appear white because water vapor from the air readily freezes onto the surface. While it looks somewhat like ordinary water ice, its referred to as dry because theres no intermediate liquid phase.Dry ice density usually ranges between 1.2 and 1.6 kg/dm3.The molecular weight of dry ice is 44.01 g/mole.Dry ice is nonpolar, with a dipole moment of zero. It has low thermal and electrical conductivity.The specific gravity of dry ice is 1.56 (water 1). Dry ice sinks in water and to the bottom of drinks.While the white vapor released when dry ice sublimates does contain some carbon dioxide, its mostly water fog produced when the cool gas condenses water from the air.When dry ice is added to food—as when making ice cream or freezing fruit—the carbon dioxide carbonates the liquid and can react with water to form dilute carbonic acid which adds an acidic or sour flavor.When dry ice sublimates, some of the carbon dioxide gas immediately mixes with air, but some of the cold dense gas sinks. Carbon dioxide concentrations increase near the floor of a room in which a lot of dry ice is being used. Dry Ice Safety Contact with dry ice can result in frostbite and cold burns. Avoid allowing any direct contact between dry ice and the skin, eyes, or mouth.Always use properly insulated gloves when handling dry ice.Always use dry ice in a well-ventilated area. Although dry ice and carbon dioxide are nontoxic, since it can sink and displace air near the ground the use of dry ice may present a respiratory hazard. Also, when it mixes with the air, theres more carbon dioxide (less oxygen) in each breath. Do not eat or swallow dry ice.Never seal dry ice in glass jars or other closed containers. The pressure buildup may result in breakage or bursting.

Kurtzs Affect on Other Characters in Heart of Darkness...

We are always taught to appreciate the little things in life; the things that don’t seem to have much of significance at first but end up meaning the world to us. These small things have a value so great but so hidden that they are usually taken a granted for. In The Heart of Darkness by Joseph Conrad, there are a few characters that aren’t present in the book for a large amount of time but have a great affect on the story. Kurtz is one of these characters. Kurtz is introduced towards the end of the story but he has an affect on the action, the theme and the other characters development even when he isn’t present. Kurtz is a power hungry man who achieved his power by getting into the ivory business and using shady techniques. He also†¦show more content†¦Darkness is a major theme in The Heart of Darkness. Kurtz is unaware of his own darkness which leads to his downfall. He cannot see what kind of person he has become and how the darkness of the jungle ha s completely taken over him. The jungle is so secluded and mysterious that it actually influences Kurtz’s bad behavior. Kurtz becomes greedy and powerful but never realizes that this behavior is bringing him down until he is on the verge of death. Kurtz last words, â€Å"The horror! The horror!†(63) show Kurtz’s realization that the darkness had consumed him. Kurtz himself is one of the biggest examples of darkness in this book. The final thing Kurtz had an affect on was the other characters development; specifically Marlow’s. Marlow spent his journey on the Congo listening to so many stories about Kurtz that he becomes obsessed with meeting him. At one point in the story, Marlow finds out there is a possibility that Kurtz is dead and he admits that, â€Å"For the moment that was the dominant thought. There was a sense of extreme disappointment, as though I had found out I had been striving after something altogether without a substance† (41). When Marlow finally meets Kurtz he is a little disappointed. He finds out that Kurtz actually isn’t as amazing as he expected. Marlow is thrown a back but doesn’t give up complete hope.

Marketing Strategy in ecommerce industry Free Essays

Introduction Technological development has led to formulation of quite a number of strategies aimed at elevating marketing in line with the current electronic age. Amazon and eBay provide us with a perfect example to the extent to which e-commerce can help in the continued growth of business. In the traditional marketing strategy, the model used is the Four P’s model. We will write a custom essay sample on Marketing Strategy in ecommerce industry or any similar topic only for you Order Now That is, there has to be product, place, price and promotion. The commodity offered on the market to attract attention or intended to be offered for acquisition is the product. When you have your product you must also have the platform which will act as the venue of meeting between the targeted client and the product in question. The value attached to the product and which is the target channel to the generation of revenue is the price. The price attached or tagged on the product need not necessarily be the price at which it is sold. This is because the process of selling is subject to many constraints, bargaining being one of them. Customers or targeted customers need information about the product, its characteristics and distinguishing features in order to make their purchases. Promoting the product therefore helps in ensuring that this role is played. It ensures awareness of the product by the potential customers. It is done in several ways. Advertising is one of the ways through which this promotional activity is carried out. The model applied in e-commerce strategy is more complex than what we have discussed above. However,   Ã‚  it is good to also note that it is very essential; that both traditional model and this advanced model be fused together in order to create a smooth transition without leaving a hanging gap. According to Allen and Fjermestad, integrating the new strategic frameworks with the traditional marketing model a more thorough framework can be developed. Due to great expansion that has been seen in the area of internet use, which means that the number of internet users has immensely increased, there is need to come up with a model that can serve the needs of all these customers so that businesses do not lose the goodwill of the very customers whose satisfaction the existence of the business depends on. If the satisfaction of the customers is not assured then the business can be sure to lose their confidence yet it is fundamental that the business reassures every customer of satisfaction. In fact, information apart from providing awareness, it is a product on its own.   It is therefore important to examine the problems that the e-commerce faces by critically looking at the marketing mix. In addition the four P’s do not lose meaning but rather the gain meaning. Data required As we have indicated above, data is a product on itself in addition to being a means of creating awareness to the benefit of a given product offered by a company. The product can either be a service or a good. Companies in need of obtaining data through quick online connection need to license eBay Market Data. After licensing eBay Market Data, they can access AERS (Advanced Economic Research Systems) data services online. Companies can get online quickly with time tested search technologies that produce correct analysis using the most efficient techniques possible. Before we look into the kind of data a company would need it is good to understand the setting in which the data will be situated. Allen and Fjerstand go ahead to state that the development in technology has allowed the information about the product or service to be separated from the product or service itself (Allen and Fjerstand). This, they say, has three elements: content, context and infrastructure. Content is what is being sold and could be information, service or a physical product. Context is how the product is presented for exchange. This method of presentation is vital to winning the consumer loyalty. Once the consumer loyalty is won, there is assurance of large and similar transactions taking place. Infrastructure on the other hand is the way in which the buyer and the seller are brought together in order for the transaction to be executed. There is need to understand that mentioning marketing we must have two kinds of information. We must have consumer information and product information. Therefore the data required falls under the two categories of information. The consumer has to be equipped with the full information about the product before making good the urge to purchase. In addition, the fact that the whole process internet selling is quite intangible increases the risk involved. The seller also needs to have information about the buyers. It is important that the seller understands the location of the customer, preferences and tastes. The customer will also need to know about shipping, physical features of the product on offer. Location of the data Advanced Economic Research Systems provide a wide range of data systems which in turn provide location for access of data. The following are some of the data systems that can act as location for data. eBay Category Structure Lookups eBay Smart Search Technology eBay Demographics Data Systems eBay Market Research (Customized Reporting) eBay Shipping Data Systems The method used to inquire about the information is just a click on the mouse and the navigator takes you to the required center. Analysis of the data It is vital that correct information is gathered concerning the customer or the product. If this is not done, there is possibility of collecting the wrong information thereby either buying the wrong product or providing buyers with the wrong product. Coming up with a comprehensive marketing is a challenge which has several advantages that give a strong of go on. It allows reduced warehousing by the companies thereby reducing storage costs and holding costs and reduced inventory costs due to automation. Internet selling is just to all companies big and small since any company is able to operate internet. There is possibility for companies to reach customers who are far away and who the company would otherwise not have the ability to sell to in their localities. Internet has enabled a one to one marketing in addition to creating room for 24-hour operation. Lastly, it provides a unique form of market research for information about the market. The internet has also its own demerits. The rapid growth in internet use has made it difficult for the companies to cope with high demand and manage distribution. Secondly, it is possible for transactions to take to long before being executed. This is because it is easier for buyers to forget after making an order due to dalliance. Lastly, apart from the fact that it could hard to find some sites, there is a barrier created between the buyer and the company since the products can’t be seen in person. Achievement of any framework developed should be measured in terms of customer satisfaction such that its failure would be seen through its failure to satisfy the targeted customers.  In conclusion, we ca say that there has been an enormous increase in the demand for information which can be justified by the increase in internet connectivity. This means that there is need to be developed a strategy that will ensure effective management and sustained distribution to customers. Reference: Checking out. (2000, March- April).

Public Health in 1665 Essay Example For Students

Public Health in 1665 Essay Ring around a roses, A pocket full of Poses, A tissue! A tissue! We all fall down! Even today, children innocently chant this old nursery rhyme, bringing the old saying into reality, Ignorance is Bliss. Its eerie, to think that this old rhyme in fact gives a perfect description of one of Europes worst nightmares, the Great Plague. Many people forget the horrors of the Plague, and when they do remember and think about it, Public heath is rarely a factor that plays a big part when people start to think things through. There were quite a few public health measures in 1665 the time of the plague. However, how many of these measures worked? An important fact to remember is that in those times, opinions and actions were either based on or blamed on religion and superstition. For example, people started marching across the country, punishing themselves on the basis that the plague was the result of all of mans sin, whilst trying to persuade people of their cause. Also, charms were used by some cultures, such as the Abra Kadabra charm, which was either carved, or worn as protective jewellery to ward off the evil spirits causing the plague. It looked similar to the image below. A B R A K A D A B R A B R A K A D A B R R A K A D A B A K A D A K A D A One measure they had was that of the red cross. This is where they would paint a red cross on the doors of people who were diagnosed with the plague. I think this would have worked because it would let people know who had the plague, so that they could avoid falling ill themselves. A law was made, saying that once someone was ill with the plague they were to stay in their house. Anyone who happened to live in the same house as the unfortunate soul was also locked in, with fear that they could spread the disease. Beggars were not allowed to wonder the streets at anytime, and were executed immediately for doing so without a given reason. All of these, although sensible ideas (apart from the execution..) would not contribute towards public health, as the disease was not contagious in the human community. It was in fact passed on from fleas living on black rats, but this knowledge had not yet been developed. If someone was bitten by this flea, then their life expectancy from that moment would be between 23-29 days. Examiners were appointed by people of high medical authority. It would be their task of travelling around England, checking to see who had the plague, and ensuring that the correct orders were being fulfilled by the town. I think that this would have helped to make things more organized, which on the whole would make a big difference, because people would be aware of which towns to avoid. However negative my views on the Public Health situation in 1665 might sound, I would hate for anybody to get the idea that the medical procedures and scientific methods were completely useless. Although very strict with laws, crime and punishment, the government took pride in being organized. They took this to the point of searching bodies, apparently to ensure everyone was dead before burial. One conspiracy is that they were in actual fact looking for valuables that could be useful, or else sold for a great profit. Despite their unintentional propaganda, many citizens were buried alive, simply because there was no known cure for the disease. Now, in the process of this, the corpses were counted, and accurate records were taken of the plague victims. This was effective in positive ways, because it encouraged the government to be more efficient when it came to statistics. .u6619944b86afb9b4ebf5dbb3e66ac879 , .u6619944b86afb9b4ebf5dbb3e66ac879 .postImageUrl , .u6619944b86afb9b4ebf5dbb3e66ac879 .centered-text-area { min-height: 80px; position: relative; } .u6619944b86afb9b4ebf5dbb3e66ac879 , .u6619944b86afb9b4ebf5dbb3e66ac879:hover , .u6619944b86afb9b4ebf5dbb3e66ac879:visited , .u6619944b86afb9b4ebf5dbb3e66ac879:active { border:0!important; } .u6619944b86afb9b4ebf5dbb3e66ac879 .clearfix:after { content: ""; display: table; clear: both; } .u6619944b86afb9b4ebf5dbb3e66ac879 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u6619944b86afb9b4ebf5dbb3e66ac879:active , .u6619944b86afb9b4ebf5dbb3e66ac879:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u6619944b86afb9b4ebf5dbb3e66ac879 .centered-text-area { width: 100%; position: relative ; } .u6619944b86afb9b4ebf5dbb3e66ac879 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u6619944b86afb9b4ebf5dbb3e66ac879 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u6619944b86afb9b4ebf5dbb3e66ac879 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u6619944b86afb9b4ebf5dbb3e66ac879:hover .ctaButton { background-color: #34495E!important; } .u6619944b86afb9b4ebf5dbb3e66ac879 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u6619944b86afb9b4ebf5dbb3e66ac879 .u6619944b86afb9b4ebf5dbb3e66ac879-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u6619944b86afb9b4ebf5dbb3e66ac879:after { content: ""; display: block; clear: both; } READ: True Brand Loyalty EssayAll in all, the public health measures in action throughout the plague did indeed work, and were effective in both positive and negative ways. .
