Discussion/Conclusion: In this chromatography lab, we separated food coloring into their component dyes using chromatography paper. When we put the piece of chromatography paper in the solvent, the paper absorbs that liquid due to capillary action. The basic colors of the ink spot will separate out into bands, and you can see the different colors that are in the ink to produce that specific color. The smallest molecules will travel basically at the same rate the solvent travels up the chromatography paper. The larger molecules will travel slowly and will stay near the bottom. Our results of our experiment were a little different then the other groups. We all matched only a couple of the Rf values, but some of our distances were a little different. We probably took our chromatography paper out before or a little later then some people, because not all of our colors were had the same measurement. It would be interesting to try using a different kind of solvent to see how much of a difference it makes when the colors separate, because our blue never really separated into the different colors that make it. It would be cool to see either if you need to use a difference solvent or leave the chromatography paper in the solvent longer then weShow MoreRelatedLab Report On Chromatography And Lab1206 Words   |  5 PagesColumn Chromatography and TLC of Spinach Group Experiment 3 – Individual Lab Report (Save as pdf and submit, due by 12:00 NOON one week after experiment) Last Name: Wang First Name: Zoey Lab Partner(s): Sue Wang TA Name: Sosthene Date Lab Performed: Nov. 12, 2015 Date Lab Submitted: Nov. 12, 2015 Group A, B, or C: B Comments for Grading TA: (Please indicate if you performed the lab on a day other than your regularly scheduled day and/or with a TA other than your regular TA).

The current suppliers may be replaced with overseas or domestic suppliers as well. If Harley wants to ensure total control and quality for its customers it could also choose in-house production. Since Harley relies on brand recognition, the buyers of Harley-Davidson motorcycles have great influence over production decisions. The threat of substitute products for Harley motorcycles is average because of the brand recognition that Harley enjoys. If riders are not looking for the Harley-Davidson image and want a cheaper motorcycle, they may look at other brands. Rivalry in the industry is high with low-priced competitors such as Honda, Yamaha, and Suzuki. However, Harley-Davidson is an American icon with a strong image of quality and freedom on the open road over the years. MarketingStrategy One of the largest marketing strategies for Harley-Davidson was the creation of HOG (Harley Owners Group). This allows owners to share experiences and network through rides, rallies, and other events. Another successful marketing strategy Harley created in 2000 is Riders Edge which provides lessons for basic and advanced motorcycling skills. About 35% of the students in Riders Edge are young adults and 37%o enrolled are women (2009 Harley-Davidson Annual Report).

Drowling Mountain free essay sample

It was August 2011 and Martin Cartier, senior board member of Drowling Mountain, was beginning to feel the pressure of Drowling Mountain Ski Resort’s 2010 general meeting that was coming up in two months. Drowling Mountain had historically been the ski resort of choice for the local residents of Syracuse, New York. However, the company had recorded losses for the past two years. At last year’s annual general meeting, Cartier explicitly stated that he would bring the company to sustainable operations. He felt personally responsible for the company’s struggles, since he was the longest-serving member on the board. Management had been keen on developing a new marketing plan focused on new pricing schemes and increasing sales, but Cartier thought an advance meeting to discuss the plan with select board members would be advantageous. He held significant influence in the forthcoming meeting in October, and any recommendations that he made were likely to determine the future success of the company.

Internet Censorship Essays - Internet Memes,

Internet Censorship Mr. Speaker, distinguished members of the house, The opposition concedes that proctecting children and to enable adults to avoid material which offends their personal Having said that, we must find realistic and practical solutions in order to address this issue. Is regulating the internet the answer? Before answering this question, there are many factors to be considered. As the member of the opposition has stated, no single set of standards is appropriate to all users, how can we regulate and deem what's appropriate for one, everyone is different. What one may find offensive on the net, others may not. By restricting the flow of information on the internet, the public will not be able to obtain every possible information which is available to them. Although there will always be certain sites which emits offensive material, it gives us a true balance of our society. By making the internet a perfect world will mislead the public's perception of our true society. Mr. Speaker, the public should have the right to choose which kind of information he or she would like to view. The users should be given the responsibility of private censorship. Like in other cases, adults must provide children with a safe and supportive environment in which to play and learn in. This can be done by subscribing to a filtered Internet Service Provider or by installing a filtering software, it should not be required as the Honorable Prime Minister is proposing. Self-censorship should be decided by the users themselves and not regulated by the government. The Prime Minister has also maintained that there needs to be a rating authority for websites on the internet. Mr. Speaker, although this may seem appropriate, it would be almost impossible to implement. We must remember that unlike print media, one of the advantages of having the internet is to let individuals who have no access or who cannot afford a publisher, the opportunity to be heard. With the amount of information uploaded every second onto the internet, it would be very hard for a rating authority to anaylize these uploads. If a suitable rating must be given before any information is to be displayed on the internet, webmasters would have to wait a considerable amount of time before their work can be viewed over the internet. Mr. Speaker, as my member of opposition as stated, by banning or blocking out certain websites will result in a high social cost, this can be controlled locally, but not on a global scale. The effect would be minimal if not noticeable, and the cost of implementing this would be very high. There are no practical ways of restricting the users, in an era of extreme information fluidity in which every barrier to information can be by passed in several ways will make it very hard for the government to make such a restriction on the internet. Any knowledgeable user can log online and use a different proxy server to by pass these barriers. The Minister of the Crown has expressed there are harmful informations available on the internet which should be regulated. Getting information, such as instructions to build a bomb can certainly cause harm to the public if it is in the wrong hands. However we must realize that by taking such information off the internet will not be the answer. These harmful information can be obtained through many other mediums. Mr. Speaker, information of how to build a bomb can be obtained at your local library, banning certain information on the internet will not be the solution. Stopping and capturing individuals who present harm to the society should be the issue, it would be ignorant to name the Internet as the scapegoat. As for regulating copyright materials on the internet, the government has not proposed any practical and realistic ways to go about this. Problems for the protection of the rights of the different industries, be it music, print and so on, should be addressed. But once again, The Crown presents a false image to the public, regulating the internet to uphold copyright will not solve the problem at hand. Mr. Speaker, the internet presents a minicul porportion of
