Electron Microscopy Electron microscopy is used to examine specimens which require greater detail than can be seen when using the light microscope. In comparison to light microscopes electron microscopes provide a clearer picture‚ greater magnification and greater resolution. There are two types of electron microscope; the scanning electron microscope and the transmission electron microscope. Electron microscopes use electromagnetic and electrostatic lenses and some are able to magnify the specimen

Not many people understand the vast difference between video art‚ and film‚ but when you actually begin to understand the different genres‚ it becomes apparent that they just are not the same thing. On a base level‚ the objectives of both are generally different‚ initially‚ video art is more about experimental expressive freedom‚ and film is more centered on entertainment‚ though there are some instances when they do overlap‚ where the film makers decide to push the boundaries‚ and experiment‚ or

To What Extent does the Sugar Concentration of Water Affects Its Refractive Index? 1. Introduction 1.1 Background Why do object when placed in a bucket of water bend? This is not magic but it is a property of light known as refraction. The bending of light when it travels from one medium to another is known as refraction. Different mediums have different densities and density is defined as the amount of mass per unit volume. The higher the density‚ the higher is the

The microscope has been one of the greatest inventions in the history of science and has had the most impact on the course of science. Ever since the first microscope was invented in 1590‚ they have improved our knowledge in basic biology and biomedical research‚ as well as many other things‚ all of which are important. The smallest object a human can see with the naked eye is 0.2 mm‚ for example‚ algae cells. The light microscope‚ however‚ allows us to see things almost 1000 times smaller that what

1. Nature of Psychology Role of a psychologist – Psychology is the scientific study of behaviour and mental process in humans. Psychologists seek to understand thoughts‚ feelings and behaviour and the factors that underlie their development and influence them. What does behaviour and mental processes mean? Term behaviour refers to any observable action made by a living person. The term mental processes refers to an individual’s thoughts and feelings that are personal and cannot be directly observed

Problem 1: What are the enabling technologies need to be developed for this system? The system‚ because it should be usable from home‚ needs to be built to work over the internet. The infrastructure needed to implement to such a system would be: Fiber-to-the-x for the last mile in the telecommunication network for high-speed access to the system. This would give users of the system fast and reliable access to the application for the instant public referendum. Internet enabled devices must exist

1. What happened to the orientation of the letter? Draw the letter “e” look under the 4X objective. 2. When you move the slide to you right‚ in which direction does the image move. 3. What happened to the size of the field as you switched from the 4X to the 10X to the 40X objectives? 4. What happened to the brightness of the object as you switched from the 4X to the 10X to the 40X objectives? a. As we increased the magnification power of the microscope‚ the brightness diminished. 5.

4.4 Quadrature phase shift keying (QPSK) Quadrature phase shift keying (QPSK) has twice the bandwidth efficiency of BPSK since two bits are transmitted in a single modulation symbol. In the phase of the carrier takes on one of four equally spaced values‚ such as 0‚ π/2‚π and 3π/2‚ where each value of phase corresponds to a unique pair of message bits. The Quadrature phase shift keying (QPSK) signal for this set of symbol states may be defined as s_QPSK (t) =√(〖2E〗_s/T_s ) cos[〖2πf〗_c t +(i-1)π/2]
