Tethered cord syndrome Tethered cord syndrome is a stretch-induced functional disorder associated with the fixation (tethering) effect of inelastic tissue on the caudal spinal cord‚ limiting its movement. This abnormal attachment is associated with progressive stretching and increased tension of the spinal cord as a child ages‚ potentially resulting in a variety of neurological and other symptoms. Due to the variation of the growth rate of the spinal cord and the spinal column‚ the progression of

The movie Man on Wire gave me this type of experience‚ helping me to re-discover the adventurous part of me that I hide deep inside of my soul. Man on Wire is a documentary directed by James March about a Philippe Petit and his journey to walk across in the middle of the World Trade Center on a wire back in 1974. What made me interested in the film in a point of view of student who is freshly leaning elements

affects the resistance of a piece of wire. Wire is made up of atoms. Electric current is a flow of electrons‚ and it is these electrons that collide with the nucleus of the atoms. Every time this happens‚ it causes resistance. The build up of friction is what produces the heat. There are many variables that could affect the resistance of the piece of wire: Length Potential difference Tension Temperature Diameter Shape Material of the wire I have chosen to do length because

investigate how the resistance of a wire is affected by the length of the wire. Theory What is resistance? Resistance is a force which opposes the flow of an electric current around a circuit so that energy is required to push the charged particles around the circuit. The circuit itself can resist the flow of particles if the wires are either very thin or very long. e.g. The filament across an electric light bulb. How is it measured? The resistance of a length of wire is calculated by measuring

resistance of a wire Introduction: Resistance is a force‚ which opposes the flow of an electric current around a circuit. Resistance is measured in Ohms. George Ohm discovered that a circuit sometimes resists the flow of electricity. He called this ’RESISTANCE.’ He even came up with a rule for working out the resistance of a circuit‚ which was: R= V ÷ I V- Volts I- Current R- Resistance Ohms law says the more resistance means more energy is needed for the current to pass through the wire.

Hirschi’s Social Bond Theory Describes D’Angelo Barksdale in The Wire Travis Hirschi’s dissertation‚ which eventually became a well-respected and commonly used book in criminology‚ had within it one of the most influential theories of crime that was tested with data and supported with results. The dissertation became known as Causes of Delinquency and was published in 1969 (Kozey‚ 2012). The general theory states that delinquency takes place when a person’s bonds to society are weakened or broken

Scientists at the University of California‚ LA used non-invasive spinal cord stimulation to provide a completely paralyzed man‚ the ability to step out in a bionic device. Breakthrough for paralysis patients Mark Pollock‚ a 39 year-old man who was paralyzed from the waist down for four years prior to the study‚ was able to voluntarily control a robotic exoskeleton to take a few thousand steps. This is the first time that a person with paralysis was able to voluntarily control his muscles and work
