the size of a firm and its growth rate are independent.[1] The law of proportionate growth gives rise to a distribution that is log-normal.[2] Gibrat’s law is also applied to cities size and growth rate‚ where proportionate growth process may give rise to a distribution of city sizes that is log-normal‚ as predicted by Gibrat’s law. While the city size distribution is often associated with Zipf’s law‚ this holds only in the upper tail‚ because empirically the tail of a log-normal distribution cannot

Two types of grinding machines In materials processing a grinder is a machine for producing fine particle size reduction through attrition and compressive forces at the grain size level. See also crusher for mechanisms producing larger particles. In general‚ grinding processes require a relatively large amount of energy; for this reason‚ an experimental method to measure the energy used locally during milling with different machines was recently proposed. Ball mill A typical type of fine grinder

What are particle accelerators used for? A particle accelerator is a device that uses electric fields to propel electrically charged particles in a vacuum‚ which approach the speed of light‚ towards each other and collide. The result hopefully being that the kinetic energy in the particles and other energy converted into subatomic particles or various types of nuclear radiation. There is more than one type of particle accelerator; they come in two basic types: • Linear • Circular Linear

"What is the God particle?" Answer: The "God particle" is the nickname of a subatomic particle called the Higgs boson. In layman’s terms‚ different subatomic particles are responsible for giving matter different properties. One of the most mysterious and important properties is mass. Some particles‚ like protons and neutrons‚ have mass. Others‚ like photons‚ do not. The Higgs boson‚ or “God particle‚” is believed to be the particle which gives mass to matter. The “God particle” nickname grew out

Magnetic particle inspection (MPI) - Is a non-destructive testing (NDT) process for detecting surface and slightly subsurface discontinuities in ferroelectric materials such as iron‚ nickel‚ cobalt‚ and some of their alloys. The process puts a magnetic field into the part. The piece can be magnetized by direct or indirect magnetization. Direct magnetization occurs when the electric current is passed through the test object and a magnetic field is formed in the material. Indirect magnetization occurs

Karla Alvarez Chemistry Period One Subatomic Particle The electron is extremely small compared to all the other parts of the atom. It is negatively charged. The negative charge balances out the positive charge of the protons in the atom. Electrons are found in the electron cloud that surrounds the nucleus of an atom. The clouds are generally organized into shells. Electrons move at a quick pace‚ so you never really know where they are specifically. But after years of doing experiments‚ scientists
