Preferences are how a consumer chooses a certain product. Whether you drink Coke or Pepsi usually depends on which you prefer. Personally I prefer to drink Coke. Some people argue though that markets are becoming homogenized such as Dr. Levitt. He argues that since the world preferences are becoming more the same‚ companies should standardized their products. This help to drive prices down and push the quality of a product up. (D. Theodore Levitt). There are others who argue another point

The project Retrofit Standardization Initiative tries to reach the goals that reduce energy consumption‚ and foster a more sustainable for residential buildings. In order to reach the goals‚ there are five energy efficiency measures are required to able to be implemented in hundreds of thousands of similar small homes. Also‚ these five measures need to minimizes the cost and time. Buildings have a life span that can lasts for 50 to 100 years. So the task is that the measures that design for the

fostering individuality and personal achievement. Teachers are teaching to the tests and students are not learning. While the US ranks high among other nations‚ it not part of even the top 15 education providers in the world. For these reasons standardization is not the answer for increased educational performance. An opposition of this statement is that national standards would provide clear instructions

Experiment #5: Acid Burn!!! Introduction The goal of this lab was to correctly prepare a 0.2M solution of NaOH‚ identify highly acidic household cleaning chemicals‚ and determine their concentration (molarity) through titrations using the previously prepared 0.2M NaOH solution. Experimental First‚ to create 0.5L of 0.2M solution of NaOH‚ standard 3M NaOH solution was obtained. Next‚ calculations were performed to determine the amount 3M NaOH necessary to create 0.5L of the 0.2M solution and‚ as

1.2.4.4 Sub-criteria standardization The standardization process consisted in conversing cell values of the sub-criteria layers into a common [0-1] scale. The minimum 0 corresponds to the less desirable condition with regards to aquifer recharge with reclaimed water and 1 the most desirable condition. The cell values of all continuous numerical sub-criteria (e.g. slope‚ soil salinity and unsaturated zone depth) were rescaled using fuzzy linear membership functions. For categorical layers (e.g. soil

Gives best results when 1o alkyl halides are used. Mechanism is SN2. Alkoxides may be prepared by reacting an alcohol with NaH or by reacting an alcohol with Na metal. Phenoxides may be prepared by reaction of phenols with NaOH ROH + NaH ROH + Na ArOH + NaOH RO Na - - + + H2 RO Na + + 1/2 H2 + ArO Na - + H2O When 3o alkyl halides are reacted with alkoxide or phenoxide ions‚ elimination is the major reaction‚ not substitution When 2o alkyl halides
