ABSTRACT A Fruit battery is a device used in experiments proposed in many science textbooks around the world. It is made by inserting two different metallic objects‚ for example a galvanized nail and a copper coin‚ into an ion bridge (for example a lemon‚ a potato or paper soaked in salt water or acid). The copper coin serves as the positive electrode or cathode and the galvanized nail as the electron-producing negative electrode or anode. These two objects work as electrodes‚ causing anelectrochemical

using more and more household batteries. The average person owns about two button batteries‚ ten normal (A‚ AA‚ AAA‚ C‚ D‚ 9V‚ etc.) batteries‚ and throws out about eight household batteries per year. A battery is an electrochemical device with the ability to convert chemical energy to electrical energy to provide power to electronic devices. Batteries contain heavy metals such as mercury‚ lead‚ cadmium‚ and nickel‚ which can contaminate the environment when batteries are improperly disposed of. When

Introduction In the context of criminal law‚ "assault and battery" are typically components of a single offense. In tort law‚ "assault" and "battery" are separate‚ with an assault being an act which creates fear of an imminent battery‚ and the battery being an unlawful touching. Assault and battery are intentional torts‚ meaning that the defendant actually intends to put the plaintiff in fear of being battered‚ or intends to wrongfully touch the plaintiff. The wrongful touching need not inflict

SIMULATION • WHAT is Simulation ? • WHY is Simulation required ? • HOW is Simulation applied ? • WHERE is Simulation used ? DEFINITION • Simulation is a representation of reality through the use of model or other device‚ which will react in the same manner as reality under a given set of conditions. • Simulation is the use of system model that has the designed characteristic of reality in order to produce the essence of actual operation. • According to Donald G. Malcolm‚ simulation

This simulation game was developed by Sisk (1976). Basically‚ there are ten imaginary countries (Shima‚ Myna‚ Ila‚ Usa‚ Pam‚ Bonay‚ Shivey‚ Lani‚ Ranu and Bili) and each of these countries has three key elements to be considered: defense‚ resources and demography. The main purpose of this game‚ understanding the importance of negotiation and interdependence between countries. I would like to make some changes in the game for my class. Every student or group will choose their imaginary country.

there were batteries slim‚ flexible and also powerful enough to run the gadgets. The batteries‚ it turns out‚ are the main barrier to modern electronics design. But in a small‚ brightly lit lab in an office park behind the Oakland Airport in Alameda‚ Calif.‚ a young startup called Imprint Energy‚ is using research created at the University of California‚ Berkeley to develop just such a battery that could free gadget makers from the constraints of the standard lithium ion battery. Well‚ that’s
