and focal point are principles of art that draw attention to specific locations in a work. Emphasis is the principle by which an artist draws attention to particular content. A focal point is a specific place of visual emphasis in a work of art or design. Most works of art have at least one area of emphasis and multiple focal points. Those few artworks that do not have areas of emphasis or focal points usually have little or no variation. An artist can emphasize focal points through the use of line

mixture‚ and (c) the density of the mixture. 3 2. A piston–cylinder device contains 0.85 kg of refrigerant-134a at 10°C. The piston that is free to move has a mass of 12 kg and a diameter of 25 cm. The local atmospheric pressure is 88 kPa. Now‚ heat is transferred to refrigerant-134a until the temperature is 15°C. Determine (a) the final pressure‚ (b) the change in the volume of the cylinder‚ and (c) the change in the enthalpy of the refrigerant-134a. 3. Determine the specific volume of superheated

demonstrate the working principles of industrial heat exchangers ii. To investigate the efficiency of the heat exchanger in parallel and counter flow arrangements 1.0 INTRODUCTION A heat exchanger is equipment in which heat exchange takes place between 2 fluids that enter and exit at different temperatures. The main function of heat exchanger is to either remove heat from a hot fluid or to add heat to the cold fluid. The direction of fluid motion inside the heat exchanger can normally categorised as

The Effects of Using the Heat Shock Treatment to Deliver a Vector in Genetic Transformation Introduction: In this experiment we are testing what is required for E. coli to successfully grow on LB (Luria Broth) plates with ampicillin and determining if any genetic transformation has occurred. By combining +pGLO LB and ampicillin we should get an ampicillin resistant gene and by using –pGLO we should create a non-genetic resistant bacteria. The pGLO plasmid has the GFP (green fluorescent protein)

In explosive atmospheres and in undersea applications‚ special connectors must be used. This paper describes a technique‚ the contactless energy transfer system (CETS)‚ by which electrical energy may be transmitted‚ without electrical connection or physical contact‚ through nonmagnetic media of low conductivity. The CETS‚ which has been used to transfer up to 5 kW across a 10-mm gap‚ employs high-frequency magnetic coupling and enables plug-in power connections to be made in wet or hazardous environmental

Title: Specific Heat Capacities of Metals Experiment Date: 3/28/2012 Report Date: 4/4/2012 Purpose: The purpose of the lab is to measure the specific heat capacities of aluminum‚ steel and brass. Theory: The amount of heat (ΔQ) required to change the temperature of an object is proportional to the mass (m) of the object and the temperature change (ΔT) of the object. ΔQ= cmΔT where c is called as the specific heat capacity of the material. In the calorie units system the unit of quantity

Extra Credit Assignment Energy Transfer in living systems Energy is the capacity to do work. All living organisms require energy for carrying on their vital metabolic activities. The primary source of energy for living system is solar radiation. The radiant energy of sunlight cannot be utilized directly by all living organisms. This ability rests only with the green plants. All the other organisms have to meet their energy requirement only through the green plants. Energy that flows in the living
