MULTIPLIER AND ACCELERATOR THEORY The Keynesians‚ have offered a demand side explanation of the business cycle. According to them‚ the fluctuations in output and employment in the country are caused by fluctuations in aggregate demand. The ups and downs in aggregate demand are caused by changes in the volume of investment. The volume of investment is directly related to the marginal efficiency of capital. The investment increases in response to higher marginal efficiency of capital and decreases

1. The tying factor between the two scientists of The New Accelerator and The Man Who Evolved is logic-stopping passion. They are both incredibly passionate about their work until it consumes them‚ Pollard being "the man who evolved" (Edward Hamilton) and Gibberne being the "Chemist of considerable eminence" (H. G. Wells). One perishes due to this passion‚ the other does not. Before we the reader‚ personified into the stories by rather reserved first-person narrators‚ are allowed to observe the

Sub Atomic Particles and the New Large Hadron Collider Many non-scientists still believe that the atom is the smallest element in this world. Also most scientists use to believe that. However‚ since the 1960’s‚ scientists discovered that the theory is not true. They succeeded at finding that there is smaller particles than the atom using early colliders. Scientist used to use older and smaller machines to find smaller particles than the atom‚ and most of the older colliders are still in use

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

Premium Carbon Raman spectroscopy Spectroscopy
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

Vibratory screen also commonly referred to as gyratory separators or screening machines‚ are a traditional part of processing dry bulk powders. They classify materials by separating them by particle size through a screen mesh. Using a combination of horizontal and vertical movements‚ they spread the material over a screen in controlled flow patterns and stratify the product. For many years‚ the majority of vibratory separators had a rectangular or square design and employed a simple reciprocating

Introduction- The purpose of this experiment is to obtain isolation of individual species of particles from the mixed culture. This is completed through the isolation technique of streak plate. The objective of this experiment is to replicate the technique of streak plate but on a much larger scale. Because it is on a larger scale the particles are able to be visually observed as they are isolated using the streaking technique as the experiment is conducted. The benefits of the streaking technique
