study is to evaluate the effects of different levels of education and literacy on the incidence of poverty in Pakistan. Our results suggest that poverty alleviation process would be accelerated if resources are targeted at education sector especially in higher education. Pakistan presents a paradoxical situation. Until the late 1980s Pakistan had achieved a spectacular record of economic growth and reduced incidence of poverty remarkably‚ but the country had horrible social indicators. However when

Problems and Solutions in Elementary Physics by C. Bond The following sections include solutions to a number of my favorite problems in elementary physics. Some of the solutions bear aspects resembling that of a magician pulling a rabbit out of a hat. Others simply demonstrate the remarkable power of a few seminal concepts to reveal the inner workings of the real world. Most of the problems yield to solution strategies other than the ones shown‚ but these represent my own preference. At some point

DEN 302 Applied Aerodynamics SURFACE PRESSURE MEASUREMENTS ON AN AEROFOIL IN TRANSONIC FLOW Abstract The objective of this exercise is to measure the pressure distribution across the surface on an aerofoil in a wind tunnel. The aerofoil is tested under several different Mach numbers from subsonic to supercritical. The purpose of measuring the pressure distributions is to assess the validity of the Prandtl-Glauert law and to discuss the changing chracteristics of the flow as the Mach number increases

Ideas about the solar system Our understanding of the solar system has changed over many centuries. Scientists such as Ptolemy‚ Copernicus and Galileo added their ideas to our changing understanding. We observe the universe using a variety of equipment‚ from telescopes to orbiters and landers. Models of the solar system The planets and the Sun orbit the Earth in Ptolemy’s model. Our understanding of the universe has changed over time. Different civilisations have created different models to

ABSTRACT Airfoil is the main part of the airplane which contributes the lift required by the airplane to fly in the air. By varying the wing’s area and the angle of attack‚ different lift can be created and can be used to fly the airplane. This program named XFLR5 is used for determining the airfoil characteristics. It will help them to save a lot of time on computing the equations and on the trial and error

Biology 100 – Section 005 November 4‚ 2013 ACL Tears in Female Athletes ACL TEARS IN FEMALE ATHLETES The Anterior Cruciate Ligament (ACL) found in the knee connects the femur (thigh bone) to the tibia (shin) and provides stability to the knee. The ACL prevents the tibia from shifting too far forward and from rotating too far inward under the femur. The recent increase of this injury has parents‚ athletes‚ doctors‚ and coaches in fear. Athletes and parents fear the injury to due the expensive
