falls‚ making you liable for injuries. So most people rely on deicers such as salt because it does a great job melting ice‚ but it also damages concrete surfaces over time. How does salt damage concrete surfaces? Salt lowers the pH balance in the concrete. Because it is acidic‚ it weakens the strength of the concrete and increases the sizes of the pores. This allows water and other elements to penetrate the surface. Salt also attracts and retains water‚ absorbing 10% more water into the concrete.

Section II: Case Study II - The Salt Lake Organising Committee: 2002 Olympics Our analysis of the case study had the following objectives: 1. To focus on the role of the new management in redesigning the organization to ensure successful execution of the 2002 Winter Olympics; 2. To identify the practices involved in the various stages of the project life cycle; 3. To discover how testing and validation reduce risk and uncertainty when planning a one-time event such as the Olympics. The bribery

How rain came to be In the beginning salt water and regular water got along. They all lived in the same ocean and each droplet would live in harmony. They shared the undersea environment with all the fish and sea plants. Some plants and animals needed salt water more than fresh water and some needed fresh water more than salt water. This is where the problem all started. The fresh water began to become jealous because the salt water was mocking the fresh water about them being the best type of

Last Friday in class‚ we wrote a CTA about Emily Dickinson’s poem and had an ORB discussion. For the ORB project‚ our group read Salt to the Sea by Ruta Sepetys. The book is about four characters‚ who are the refugees from the World War II‚ and how they interact with each other. To be honest‚ in class‚ I did not raise any deep‚ philosophical question about what I was doing. I simply followed what I was asked to do. However‚ when I went back home‚ sitting in front of my green desk‚ having a document

Describing the appearance of bacterial colonies has been an important tool for microbiologists. On solid media‚ a colony is theoretically derived from a single cell. If well separated from other colonies‚ a colony will have a characteristic shape (both in elevation and margin)‚ size‚ color‚ and consistency. Usually‚ observation is made with the naked eye‚ but dissecting microscopes are also used. The characteristics defined by a colony’s morphology may be used at a superficial level to distinguish

Investigating Stoichiometry with Carbonic Acid Salts Problem: Testing the actual yield versus the theoretical yield of NaCl when HCl is titrated into Na2CO3 and NaHCO3. When 0.15g of both NaHCO3 and Na2CO3 are titrated with HCl‚ then 0.165g of NaCl should form from the NaHCO3‚ and 0.104g of NaCl should form from the 0.15g of Na2CO3. Procedure: Weigh 2 samples of 0.15g of dried unknown each‚ and dissolve each into 50mL of distilled water. Add 0.5 to 1mL of bromocresol green indicator until the

Case #9 1. Is it proper to multiply the average order size‚ $42.33‚ by the number of addresses (1‚300‚000) in the target mailing? a. No‚ there is far too much variability in responses‚ including a massive outlier‚ to have any confidence in this average. The response rate is very low‚ one would be concerned as to why the rate of response was only 9.2%. The question would therefore be whether the remaining 90.8% will follow the same pattern or will they buy anything at all. There is also

Conclusion I believe that the human life journey is a journey that should never be taken for granted. There are many different stages in the life journey‚ and every stage that you start and finish affects the next stage. The first stage in one’s life is one that they are unable to control. The heredity and Prenatal Development occurs when the child is inside of their mother’s womb. Although the unborn child is unable to control what happens in this stage‚ it is very critical that the mother takes
