Red wires marks the beginning of The Economist talking to people who might not yet consider themselves to be Economist readers through its marketing and advertising. It was sparked by research undertaken by the magazine last year which discovered that‚ because of the rise in the number of people going on to university‚ there are now over 3 million people in the UK whose interest in world affairs‚ travel‚ news and politics suggests an unconscious affinity with what The Economist reports on every week

Cord Blood Cells. Today medicine has reached great success in the treatment and prevention of many illnesses. Currently‚ scientists and doctors are paying more attention to technology of cells. Cord blood is the blood that remains in a newborn’s umbilical cord after birth. Cord blood‚ like bone marrow‚ is an invaluable source of a type of stem cell that can be used in a variety of medical treatments. New parents now have the option of taking an active role in treating future illness much like a

traumatic spinal cord injuries in their lifetimes that leave them paralyzed. Many people wonder if these spinal cord injuries are reversible‚ and hope to someday walk again. Although the complete reversal of paralysis is in the minority viewpoint‚ encouragement by others in similar situations has been shown to help motivate paraplegics to maintain a rehabilitation process. There are many researches about the restoration of spinal cord injuries to give hope to those affected by spinal cord injuries‚ as

Bird on the Wire by Cohen Leonard is a personal song that talks about the great challenges of humanity. The poem first starts off saying that people are very free but still confined by comparing us to birds on a wire. Then the song talks about making mistakes and hurting people but always trying make it up. I believe that this is a sad song about feeling out of luck and down‚ and always trying to find yourself from within. I personally really enjoyed the message the second verse was trying

Practical Investigation Resistance in Wire Aim: To investigate if the length of wire affects its resistance and find out how the resistance changes when the length of wire increases. Hypothesis: My prediction is that as the length of wire increases‚ the resistance will also increase. This is because current is the flow of electrons in a circuit and voltage makes the electrons flow through the circuit. The electrons have to collide with the atoms in the wire‚ which makes the electrons harder to

because the electrons would bump into more atoms‚ the longer the wire which is like using up its fuel. Material – different materials inherent resistances as they have more or less atoms in them already. Thickness – Thickness affects resistance because the thicker the wire the more paths the electrons have to avoid the atoms. Therefore the cross sectional area is larger so there is less resistance. Temperature – The hotter the wire is the more energy the electrons have to flow faster. Why do we

affects the resistance of a wire. Reworded: I am going to investigate if changing the length of a wire changes its resistance. I predict that the longer the wire‚ the more resistance it has. Planning and Preparation Independent Variable: The variable I changed was length (cm). Dependent Variable: The variable I measured was resistance (Ω). Fixed Variables: The variables I kept constant to make it a fair test; were‚ the type of wire (nichrome)‚ the thickness of the wire‚ and the temperature of the

Problem Does temperature affect the resistivity of different sized copper wires? Hypothesis I think that the resistivity will increase with higher temperatures because with higher temperature‚ resistivity is higher due to the fact the atomic lattice structure increases. Background Electrical resistivity is the measurement of how a material opposes the flow of an electrical current. On the other hand‚ electrical conductivity () is the inverse of resistivity. It is the measurement

Three different general types of spinal cord models consist of contusion‚ compression and transection \cite{rosenzweig2004}. Each model contains the different advantages and disadvantages depending on the observing study. When a blunt force exposes to the spinal cord without the destruction of the dura‚ it develops the contusion model which is the most general case in human \cite{jackson2004‚calancie2005}. The impactor is the confined tool to induce the contusion model with repeatability
