1. TEXTILE PRINTING 1.1. INTRODUCTION Textile printing is the process of applying color to fabric in definite patterns or designs. In properly printed fabrics the color is bonded with the fiber‚ so as to resist washing and friction. Textile printing is related to dyeing but‚ whereas in dyeing the whole fabric is uniformly covered with one color‚ in printing one or more colors are applied to it in certain parts only‚ and in sharply defined patterns. In printing‚ wooden blocks‚ stencils

EXPERIMENT 5 GAS DIFFUSION COEFFICIENT OBJECTIVES: Determine the gas diffusion coefficient of acetone using the established Winkelmann’s method KEYWORDS Diffusivity‚ Gas Diffusion Coefficient‚ Winkelmann’s method OVERVIEW The knowledge of physical and chemical properties of certain materials is important because very often process engineering deal with the transformation and distribution of these materials in bulk. One such property is diffusivity. Mass transfer by diffusion takes

DYING DECLARATION “Truth sits on the lips of a person who is about to die” Introduction A Dying Declaration means the statement of a person who has died explaining the circumstances of his death. It can be said to be a statement made by a mortally injured person‚ indicating who has injured them and/or the circumstances surrounding their injury. The injured is aware that he/she is about to die and while the declaration is hearsay‚ it is admissible since it is believed that the dying person does not

Is PVC an acceptable vent material for flue gases? Installing a new water heater or furnace can be tricky for the novice HVAC technician. There are many checks that need to be done and codes that need to be followed. While not being complete with the internals can lead to a harmful situation‚ one of the most important decisions that you will have to make is what material you should make the flue out of. Most furnace flues are made out of a metal material which is a proper decision do the high

Recycling has many advantages. It can tackle environmental problems‚ save energy while reduce waste and turn the wastes into treasures. Above everything else‚ recycling can tackle environmental problems. A winning invention which is a solar water heater making by plastic bottles and milk cartons is cheap‚ simple and widely used. It not only solves the problems in Brazil but also has benefits for people. The inventor‚ Jose Alano‚ only want to reuse the waste and make contributions to the environment

The effect of different temperature on the cell respiration. Introduction： Cell respiration is the controlled release of energy from organic compounds in cells to form ATP‚and then release waste products. The process of cell respiration can take place in the presence or absence of oxygen. In either case‚the first stage of cell respiration is glycolysis.The effect of temperature on cell respiration mainly depends on the effect of temperature on of enzyme activity.Generally speaking in a certain

A voltage ΔV is applied across the ends of a nichrome heater wire having a cross-sectional area A and length L. The same voltage is applied across the ends of a second heater wire having a cross-sectional area A and length 2L. Which wire gets hotter? (a) the shorter wire‚ (b) the longer wire‚ or (c) more information is needed. 6. Two resistors‚ A and B‚ are

The proper temperature in a saltwater fish tank‚ no matter how many gallons it is‚ is 77 degrees. This is because that probably the temperature the fish and coral were kept at‚ when they were at the fish store you purchased them from. If you have a larger fish tank‚ you should have at least two heaters. Lighting is very important in your saltwater fish tank. Not only
