that Fits the Tipping Point After finished the majority part of Tipping Point‚ which Gladwell talks about the three key factors that determine whether a particular trend will tip into a social epidemic‚ I built up a better understanding to how social phenomenon appears . It is very thought provoking and useful‚ especially for our business student which will struggle in “tipping” our service or product into popular fad. It is hard not to be convincing by Gladwall’s point of view. It is really

Point of sale software gives business owners a convenient way of checking out customers and of recording sales. It can keep a record of the store inventory‚ updating it when an order is processed. It can also print out receipts‚ carry out credit card processing‚ track customers‚ etc. Point of sale software eases the flow at checkout terminals‚ while recording all the information that can help you make better business decisions. Point of sale software allows users to input via keyboard or mouse‚

software and were very limited in function and communications capability. In August 1973 IBM announced the IBM 3650 and 3660 Store Systems that were‚ in essence‚ a mainframe computer packaged as a store controller that could control 128 IBM 3653/3663 point of sale registers. This system was the first commercial use of client-server technology‚ peer to peer communications‚ Local Area Network (LAN) simultaneous backup and remote initialization. By mid-1974‚ it was installed in Pathmark Stores in New Jersey

Title: Separating the components of “Panacetin” Name: Ip‚ Wing Chung (Vincent) Lab Partner: Ma‚ Siyin Date: 2/3/2013 Introduction: The purpose of this experiment is to investigate the composition of compounds in Panacetin. Generally‚ it is made up of sucrose‚ aspirin and an unknown component‚ either acetanilide or phenacetin. SinceBy using different techniques‚ such as filtration‚ extraction‚ and evaporation‚ those three components have been isolated out‚ which is based on varies solubility

The crude naphthalene had a melting point range of 85°-90° C while the 35.4% yield of pure naphthalene had a melting point range of 70°-76° C. Recrystallization was used to purify the salicylic acid. Recrystallization is the process of dissolving the original solid in a hot solvent and then allowing the solution to cool to let the solid crystallize again. The crude salicylic acid had a melting point range of 150°-153° C while the pure salicylic acid had a melting point range of 155°-158° C. (Percent

Aim: To investigate the difference between the melting point of dark and milk chocolate. Hypothesis: If both chocolate is heated then dark chocolate will melt faster because milk chocolate has more fats Variables (i) Independent: Two substances will be tested dark chocolate and milk chocolate. (ii) Dependent: The temperature at which each substance melts

identify what analgesic Jasper was given we took samples of the different analgesics and crushed them. We used a melting point apparatus to find out what the melting point was and matched it with acetaminophen‚ aspirin‚ or ibuprofen. Then we used the Infrared Spectroscopy to determine the function group of the molecules to help us identify which analgesic was used. Between the symptoms‚ melting point‚ and results of the infrared spectroscopy we were able to identify what analgesic Jasper ingested. Results:

Preparation and melting point of Aspirin Aspirin is a painkilling drug and is produced worldwide to reduce and stop pain. Aspirin is made up of ehtanoylation of 2-hydroxbenzenecarboxylic acid in a presence of phosphoric acid. AIM: The aim of the experiment is to prepare and produce aspirin as pure as possible. I will do this threw preparing the aspirin and purifying the product threw recrystallization. I will then obtain a melting point of my product to get an estimate of its purity. By the end

The literature value for the melting point range for Trans-9-(2-phenylethenyl)anthracene is 130-133 oC. The obtained range was lower than that at 120.3 to 123.8 oC. Because it is lower than the known value‚ this means the obtain product is not completely pure. Impurities in the compound can result in a decrease in the compounds melting point‚ which is observed here. The impurities could be 1-propanol due to an insufficient drying. If the experiment was performed again‚ the product would need to be
