Theory CONDUCTORS‚ INSULATORS AND CONDUCTIVITY Conduction of electricity in electric circuits takes place due to the presence of excess electrons in materials called conductors. Electrons move in the direction in which the potential has been applied. The ability of a conductor to conduct electricity is directly proportional to the material’s area of cross section and inversely proportional to its length. Where‚ G is conductance σ is conductivity A is area of cross section

Heat energy is transferred from homes by conduction through the walls‚ floor‚ roof and windows. It is also transferred from homes by convection. For example‚ cold air can enter the house through gaps in doors and windows‚ and convection currents can transfer heat energy in the loft to the roof tiles. Heat energy also leaves the house by radiation through the walls‚ roof and windows. http://www.bbc.co.uk/schools/gcsebitesize/science/ocr_gateway_pre_2011/energy_home/1_keeping_homes_warm2.shtml Visited

Exercise 3 Neurophysiology of Nerve Impulses Activity 1 1. What happens to the resting membrane potential when extracellular K+ concentration is increased? -The resting membrane potential will become more positive when K+ concentration is increased. 2. Explain why the resting membrane potential had the same value in the cell body and in the axon. -The resting membrane potential has the same value in the cell body and the axon because the typical resting membrane potential is the same throughout

activates the muscle fibers that were innervated by the motor neuron. This study aimed to view how the muscles electrical activity changed with voluntary contractions‚ and evoked stimulation of the abductor pollicis brevis muscle‚ and measure nerve conduction velocity and the affect of coactivation. Research in the use of electromyography is important for helping those with impaired muscle

Transparent electronics is a emerging technology‚ which is satisfying the requirements of everything invisible or multi-purpose objects. Before going further let me give an example: You are travelling in a car and you want to watch a movie or video play. Now the glass shields ie window panels will turn into a tv screen and this is possible with this technology. This is helpful when the driver can’t take away his eyes from road but still want to watch out a map of route. Then front window panel

Introduction At the conclusion of this case study‚ the learner will be able to: Identify two common treatment modalities for Second degree heart block Identify a list of uses of‚ doses and contraindications for giving Beta Blockers. Recognise a Mobitz II heart block rhythm. Over the path of the paper‚ a definition of Mobitz II heart block will be given a long with what can happen to the rhythm if beta blocker medications are taken at the same time and its treatment.

How do muscles move the skeleton? Contract How may possible gametes with A/A? one What process is blocked by operons/prokaryotes? Transcription What is the least involved in translation? DNA In the picture of muscle contraction‚ know what bands decrease in size and which ones stay the same. When the muscle contracts the sarcomere gets smaller and the area between myosin filaments. What are the net products of glycolysis? ATP‚ NADH‚ Pyruvic Acid What are the net products of cellular respiration
