OBJECTIVE: 1. To demonstrate the isentropic expansion process. INTRODUCTION: In thermodynamics‚ an isentropic process is one in which for purposes of engineering analysis and calculation‚ one may assume that the process takes place from initiation to completion without an increase or decrease in the entropy of the system .If a compression or expansion of a gas takes place with no flow of heat energy either into or out of the gas - the process is said to be isentropic or adiabatic. The isentropic

Introduction The activities 3‚ 4 and 7 have been experimented. In inhibiting a Nerve Impulse‚ numerous physical factors and chemical agents can impair the ability of nerve fibers to function. In these activities they show this exactly. In these experiments‚ it showed the effects of various agents to nerve transmission. In testing the effects of ether‚ there will be a nerve that will be stimulated. The experiment is to see if ether has any permanent alteration in neural response of the nerve. I believe

Chapter 9 IMPULSE AND MOMENTUM COLLISION PROBLEMS A tennis ball and racket collision: a microscopic view COLLISION: FORCE VS TIME GRAPH A large force exerted during a small interval of time is called an impulsive force. LINEAR MOMENTUM The product of the particle’s mass and velocity is called the linear momentum p = mv As a vector quantity‚ the momentum can be represented in terms of its components: px= mvx py= mvy ALTERNATIVE FORM OF NEWTON’S SECOND LAW F = ma = m(dv/dt) =

The nerve impulse The information is transmitted by polarity changes in the membranes of cells due to the presence of neurotransmitters that alter the ionic concentration inside the cell. Moreover‚ inside the neuron proteins and ions are negatively charged . This difference in ion concentration also produces a potential difference between the outer membrane and within the cell . The value reached is about -70 millivolts (negative inside with respect to the value of positive charges outside

RUNNING HEAD: IMPULSE CONTROL DISORDER Impulse-Control Disorder Impulse-Control Disorders Impulse-Control Disorder (ICD) is a repeated impulsive action that results in negative consequences. The DSM-IV distinguish five particular impulse-Control Disorder such as: kleptomania‚ pyromania‚ pathological‚ trichotillomania‚ and intermittent explosive disorder. The DSM-IV-TR named these five disorders “Not Elsewhere Classified” and names them separately

Faber‚ University of Minnesota ABSTRACT - Much of the work on impulse buying has been concerned with defining and measuring the concept. Less effort has been directed toward determining the factors that underlie the tendency to buy impulsively. This study looks at the relationship between impulse buying tendencies and three general personality

Session 9: The Nervous System - Assignment #2 PhysioEx Assignment : Exercise 3 Neurophysiology of Nerve Impulses Activity 1: The Resting Membrane Potential 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. Increasing the extracellular K+ causes the membrane potential to change to a less negative value because when K+ ions diffuse out across the membrane they are leaving behind a net negative charge. 2. Explain

Name: _________________________________ EXERCISE 3 Neurophysiology of Nerve Impulses Laboratory Report Answer the following questions. (3 points each). 1. What is the difference between membrane irritability and membrane conductivity? Membrane irritability is the ability to respond to a stimuli and convert it in to nerve impulses. Membrane conductivity is the ability to transmit that impulse that is created by membrane irritability. 2. If you were to spend a lot of time
