BASE ISOLATED BUILDINGS What is base isolation? When a building is built away (isolated) from the ground‚ resting on flexible bearings or pads known as base isolators. It is of the most popular means of protecting a structure against earthquake forces. HISTORY The first evidence of architects using the principle of base isolation for earthquake protection was discovered in Pasargadae. One of the world’s first base-isolated structures – the William Clayton building Base Isolation

Title: Acids‚ Bases & Buffers Objectives: 1. To understand the acid-base chemistry. 2. To prepare and evaluate a buffer system 3. To measure the buffering capacity of two types of isotonic drinks. Introduction: There are acid-forming‚ basic forming and neutral food‚ however the acid or alkaline properties of a food is unable to judge by the actual acidity of the food itself. For example‚ citrus fruits such as lemon are acidic‚ but they are alkaline-forming when we consume and digest it. Therefore
