Why demand analysis of caustic soda? 2.1 CAUSTIC SODA Sodium hydroxide‚ also known as caustic soda‚ or lye‚ is an inorganic compound with the chemical formula NaOH. It is a white solid and highly caustic metallic base and alkali salt which is available in pellets‚ flakes‚ granules‚ and as prepared solutions at a number of different concentrations. Sodium hydroxide forms an approximately 50% (by weight) saturated solution with water. Sodium hydroxide is soluble in water‚ ethanol and methanol. This

Chapter 4. Dimension Reduction In this chapter we describe the important step of dimension reduction. The dimension of a dataset‚ which is the number of variables‚ must be reduced for the data mining algorithms to operate efficiently. We present and discuss several dimension reduction approaches: (1) Incorporating domain knowledge to remove or combine categories‚ (2) using data summaries to detect information overlap between variables (and remove or combine redundant variables or categories)

Partner: Stephan Villavicencio Thurs. Section Lab date: March 19‚ 1998 Report date: April 6‚ 1998 Abstract: The equilibrium between acids and bases during a titration can be used to determine several characteristics of the acid or the base. Sodium hydroxide was standardized to 0.1035 M in three acid-base titrations of potassium hydrogen phthalate (KHP). This standardized NaOH solution was then used in a series of other titrations with acids in order to gain information about those acids. The

post-harvest Tilapia aquaculture was developed. This project (PartII) is focused on product standardization and verification analysis to answer the world’s food security/global sustainability problems. This innovative technology helped address the in-breeding concerns on Tilapia production‚ as well as the problems brought by climate change to aquaculture fishes. The developed product has undergone standardization procedures using single group experimental design. Analysis of Variance (ANOVA) was used
