In evaluating the relevance of a programme or a project it is useful to consider the following questions To what extent are the objectives of the programme still valid Are the activities and outputs of the programme consistent with the overall goal Rola. M. . Shadid. , BDS, . MSc. The denture base supports the artificial teeth and consequently receives the functional forces from occlusion & transfers functional forces to supporting oral structures. Sodium hydroxide. Preferred IUPAC . name. Sodium hydroxide. Systematic . name. Sodium . oxidanide. Other . names. Caustic soda. Lye. Graphics Source: Wikipedia. Acid/Base Definitions. Arrhenius Model. Dr. Lam. TECM 4180. Objective. Students . wil. be able to define knowledge base. Students will know how a KB differs from a print manual. What is a knowledge base?. “a . special kind of database for knowledge management. A knowledge base provides a means for information to be . 1. What are . acids. and how do they taste like?. What . acids. or . acidic . solutions. do you know?. What are . acids. and how do they taste like?. Taste: . sour, tart, tangy. What are . bases. . The taste of lemons and lime, the bite of sourdough bread, and the tang of a tomato are all caused by acids. Acids may be defined as substances that produce H. +. ions in solution. Citric acid, acetic acid, and tartaric acid are shown here.. Acid and Base Notes. I can distinguish between an acid and a base.. I can list the characteristics of an acid and a base.. I can name acids.. I can name bases.. What do you think an acid is?. Give an example of an acid.. Chapter 8.1. Objectives. Describe the ionization of strong acids in water and the dissociation of strong bases in water.. Distinguish between solutions of weak acids or bases and solutions of strong acids or bases.. A special solution. Acids and bases are ALWAYS in a water solution.. Your body has water in it so they are always dangerous to living things.. Bases are just as dangerous as acids.. In low . concentrations. An introduction to the properties of acids, bases, and the pH scale. Complete the following table. Element. Atomic. #. Mass #. Protons. Electrons. Neutrons.
