JUST IN TIME PHILOSOPHY A philosophy for maintaining a competitive advantage based on the concept of continuous improvement and elimination of waste. Just-in-time is a management philosophy that originated and was applied in manufacturing organizations in Japan since the early 1970’s. In its early stages‚ JIT was utilized as a means to meet customer demand and minimize delays. The emphasis of JIT referred to a process where the production of goods met customer needs for quality and

NaOH Standardization and Titration of an Unknown Organic Acid Overview: Methods for counting the number of molecules in a sample is a major emphasis of laboratory work. In this experiment we will use the method of titration to count the number of acid molecules in a solution. Measuring mass is a relatively easy procedure to do in the lab (although a balance is expensive). Counting the number of particles requires more effort. Molecular counting can be done by setting an unknown amount of a substance

Chemistry Lab Report on standardization of acid and bases. Purpose: To prepare standardize solution of sodium hydroxide and to determine the concentration of unknown sulfuric acid solution. Data and Calculations: This experiment is divided into two parts (Part A and Part B). In the first part of experiment‚ the standardize solution of sodium hydroxide is prepared by titrating it with base Potassium hydrogen phthalate (KHP). The indicator Phenolphthalein is used to determine that whether titration

Great Religions and Philosophies. : Greek Philosophy. In the 6th century B.C‚ there began a dualism in Greek Philosophy. The development of Greek Philosophy became a compromise between Greek monistic and oriental influences‚ in other words‚ a combination of intellectualism and mysticism. Thus began the pre-Socratic philosophy. The interests of pre- Socratic philosophers were centered on the world that surrounds man‚ the Cosmos. This was during the time of great internal and external disturbances
