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

The acid-base titration curves help to find the pKa‚ Ka‚ and pH at equivalent point. At the beginning pH for HCl is 1.90 which is lower than the 3.28 for acetic acid; thus‚ strong acid (HCl) means lower pH and weak acid (acetic acid) means higher pH. Then at the equivalent point for the titration HCl-NaOH the pH is 7‚ which mans that is neutral‚ in other words there are enough NaOH mmol to neutralize the HCl mmol present; also‚ the solution contains only water and NaCl the salt derived from the titration

What is the care value base? The care value base is a range of standards for health and social care. It is designed to guide the practice of professionals working in this area. The aim of the standards is to improve clients’ quality of life‚ by ensuring that each person gets the care that is most appropriate for them as an individual. The care value base offers guidance‚ and sets standards‚ in three main areas of health and social care: ➢ Fostering equality and diversity ➢ Fostering people’s
