is non-zero‚ unlike an insulator‚ yet still several magnitudes smaller than that of a conductor. There exists a significant energy gap between the filled valence – highest range of electron energies normally present at absolute zero – and empty conduction bands – range of energies which are enough to unbind the electron from the atom and allow it to move freely within the atomic lattice – in a semiconductor‚ unlike a conductor which has very small or no band gaps and/or an insulator which has very

Heat: a form of energy Heat In physics and chemistry‚ heat is energy transferred from one body to another by thermal interactions.[1][2] The transfer of energy can occur in a variety of ways‚ among them conduction‚[3] radiation‚[4] and convection. Heat is not a property of a system or body‚ but instead is always associated with a process of some kind‚ and is synonymous with heat flow and heat transfer. Heat flow from hotter to colder systems occurs spontaneously‚ and is always accompanied by an

Magnetism Assignment # 2 Due Date: 15 November 2013 1. a) Write brief notes on the Hall effect. Show on a diagram the polarity of the Hall Voltage‚ together with a given current and magnetic field direction‚ assuming the charge carriers to be conduction electrons. [5] b) Define electric dipole and the electric dipole moment. Write down an expression‚ in vector form‚ and show graphically the electric field intensity at point P on the normal to the axis of the dipole.

short-distances within that cell. General Introduction. The nervous system is made up of two types of cell‚ neurones (nerve cells) and glia. Neurones generate electrical signals and transmit them to other nerve cells or to muscle / endocrine cells. They communicate with one another at synaptic junctions‚ usually via the release of a chemical messenger known as a neurotransmitter. Some nerve cells have a sensory role – they can detect for e.g. pressure‚ heat or light and generate an electrical signal

this case study‚ the underlying arrhythmia for the patient was determined to be atrial fibrillation (AF). Patient’s last BP measure was 80/50. Will this new diagnosis improve the patient’s BP? Not really. While adenosine may slow the electrical conduction rate of the heart‚ the pathophysiology of AF still creates a problem for a normal BP. AF occurs when multiple irritable foci‚ potentially hundreds‚ from different locations across the atrium‚ all fire at the same time. As a result‚ instead of the

At the microscopic level‚ we find two kinds of cells: the neurons and the glia i. Neurons send messages to each other and also to muscles and glands. They have changing sizes‚ shape and functions. ii. Glia- which are most of the time smaller than neurons have many
