Visual Fields in Glaucoma Evaluation of the field of vision is the mainstay of the diagnosis and management of glaucoma. The use of manual perimetry for defining glaucomatous defects is an art that is highly dependent on the perimetrist’s skill. With the advent of computers and automation‚ perimetry has changed from an art to a more quantitative science. Understanding glaucomatous abnormalities detected with both manual and automated techniques requires a thorough understanding of the

The kinetic energy of an object attached to a horizontal ideal spring is denoted by KE and the elastic potential energy by PE. For the simple harmonic motion of this object the maximum kinetic energy and the maximum elastic potential energy during an oscillation cycle are KEmax and PEmax ‚ respectively. In the absence of friction‚ air resistance‚ and any other nonconservative forces‚ which of the following equations

Properties of paper Physical Properties Basis Weight or Grammage The basis weight‚ substance or grammage is obviously most fundamental property of paper and paperboard. The Basis weight of paper is the weight per unit area. This can be expressed as the weight in grams per square meter (GSM or g/M2)‚ pounds per 1000 sq. ft. or weight in Kgs or pounds per ream (500 sheets) of a specific size. Paper is sold by weight but the buyer is interested in area of paper. The basis weight is what

If the linear momentum of a body is increased by 50%‚its kinetic energy is increased by what %? 5. A mass m covers a certain distance s under the action of a constant force‚starting from rest. The kinetic energy acquired by it depends on what power of its mass? 6. At time t=0‚a particle starts moving along the x-axis. If its kinetic energy increases uniformly with time

Application of Energy ------------------------------------------------- Forms of energy Main article: Forms of energy Energy exists in many forms: Heat‚ a form of energy‚ is partly potential energy and partly kinetic energy. In the context of physical sciences‚ several forms of energy have been defined. These include: * Thermal energy‚ thermal energy in transit is called heat * Chemical energy * Electric energy * Radiant energy‚ the energy of electromagnetic radiation *

Chapter 1 Introduction The notion of going green is not strictly a new technological concept‚ and any naturally occurring and theoretically inexhaustible energy such as wind‚ biomass‚ and solar‚ tidal‚ wave‚ hydroelectric power that is not derived from fossil or nuclear fuel is referred to as renewable energy. The relevance of these emerging fields became more pronounced when the need to produce clean‚ safe and efficient energy devices without trading off environmental friendliness arise. The current
