This is the practical part of this series on happiness. It’s quite long‚ and not necessary to read through it all. The only essential part is “The Happiness Formula” – after that feel free to bookmark or skim‚ if you prefer not to read the whole thing. This article is different to the other “how to be happier” articles I found on the internet. The other stuff seemed to be more inspirational and uplifting rather than practical. I found advice like ‘smile more’‚ ‘be myself’‚ and ‘get a cat’. This article

Introduction This experiment aimed to study the forced damped transverse vibration of a beam and verify Dunkerley’s empirical formula. According to Dunkerley’s empirical formula‚ 1f2=1fb2+1fω2 where f referring to the natural frequency of heavy beam with central load fb referring to the natural frequency of heavy beam only fω referring to the natural frequency of light beam with central load M By using the results of light damping‚ Dunkerley’s empirical formula would be studied and

Photocatalytic degradation of methylene blue using TiO2 nanoparticles Nupur Mittal Chemical Engineering‚ IIT (BHU) Varanasi. Abstract: The aim of this research is to reduce the pollution caused by methylene blue dye in waste water coming from textile industries. For this purpose‚ TiO2 nanoparticles are made as they show good photocatalytic activity in degradation of dyes into harmless products. Synthesis is done using titanium butoxide and 2-propanol. The particles formed were a little larger

The Synthesis and Determination of Empirical Formula for Magnesium Oxide Aim: To determine the empirical formula for magnesium oxide. Data Collection: Table 1 Mass of empty crucible‚ crucible + Mg (roughly 1cm pieces of a 15-cm piece of magnesium ribbon)‚ and crucible +MgxOy. (mass measured with an analytical balance). The mass of crucible + MgxOy was obtained after a continuous process of heating‚ letting cool‚ heating with water enough to immerse the content and letting cool of the Mg. Mass

EXPERIMENT 5 REDOX TITRATION: TITRATION USING SODIUM THIOSULPHATE Objectives 1. 2. To prepare a standard solution of potassium iodate for use to determine the concentration of sodium thiosulphate solution accurately. To acquire the proper techniques of carrying out a titration. Introduction Redox titrations using sodium thiosulphate as a reducing agent is known as iodometric titration since it is used specifically to titrate iodine. The reaction involved is: I2 + 2Na2S2O3 I2 + 2S2O322NaI + Na2S4O6

The Hubbart Formula Where would a hotel manager start in determining the fair price for a guest room? What is a fair value? This question has daunted innkeepers from the beginning. Charge rates too high‚ and no one will stay with you. Setting rates too low‚ and the owner makes less money. For many years in the beginning of the modern hotel era‚ hotel managers simply guessed. As unscientific as this approach sounds‚ it did work to an extent. After a hotel has been in business
