1. Review the anatomy of the brain. Which portion is responsible for keeping you awake‚ controlling thought‚ speech‚ emotions and behavior‚ maintaining balance and posture? Emotions and behavior are controlled by the hypothalamus (p.455) The cerebellum is responsible for maintaining balance and posture (p.455) The reticular formation is essential for maintaining wakefulness and in conjunction with the cerebral cortex is referred to as the reticular activating system (p.450) The Broca speech

Steam engines were the first engine type to see widespread use. They were first invented by Thomas Newcomen in 1705‚ and James Watt (who we remember each time we talk about "60-watt light bulbs" and the such) made big improvements to steam engines in 1769. Steam engines ¬powered all early locomotives‚ steam boats and factories‚ and therefore acted as the foundation of the Industrial Revolution. In this article‚ we’ll learn exactly how steam engines work.74 Steam Engine Operation The

should be exposed to more attenuation than Path 2. Also‚ as a consequence of being in the back of the forest‚ the human following Path 1 will be in the forward scattering zone of more trees than the human in Path 2. This is expected to result in more coupling e®ects from the trunks. We investigate the di®erent spectrograms for these paths in Figure 13. The same human starts with the same position and moves at the same speed for the two cases. The ¯rst step is taken with the left foot. We observe that

FREE ELECTRON THEORY Classical free electron theory of metals This theory was developed by Drude and Lorentz and hence is also known as Drude-Lorentz theory. According to this theory‚ a metal consists of electrons which are free to move about in the crystal like molecules of a gas in a container. Mutual repulsion between electrons is ignored and hence potential energy is taken as zero. Therefore the total energy of the electron is equal to its kinetic energy. Drift velocity If no electric

Effects of Diet on the Development of Cholesterol Gallstones Hannah Matich BIO 392 Dijkstra Thurs 6PM Lab 3/29/17 1 Gallbladder disease is one of the most common gastrointestinal disorders in developed countries. Gallbladder disease is typically manifested in the form of gallstones or gallbladder cancer. Gallstones affect 10-15% of people in developing countries‚ meaning 20-25 million Americans have or will have gallstones (Stinton and Shaffer‚ 2012). Though mortality rate is low;

Table of Contents INTRODUCTION 3 MATLAB SIMULATION 4 DISCUSSION 8 REFERENCE 10 INTRODUCTION Synchronous generators or alternators are synchronous machines used to convert mechanical power to ac electric power. Nowadays‚ an isolated synchronous generator supplying its own load independently of other generators is very rare. Such a situation is found in only a few out-of-the-way applications such as emergency generators. For all usual generator applications‚ there is more than one generator

Dynamic contraction Dynamic contraction refers to a contraction where movement is involved. An example is lifting of a dumbbell from either side to the shoulder. Static contraction‚ on the other hand‚ refers to a contraction where no movement is involved. Concentric and Eccentric A concentric contraction is a way of using the body’s muscles for physical tasks. A concentricmuscle contraction is a very common kind of muscle contraction. It is part of many basic physical exercises and everyday
