I usually start with the definition of work: Work = force * distance so... Force = work / distance Distance = work / force So, no. You had it backwards.
Work for what?
efficiency
work out everything within the brackets first. then work out rest of equation.
If a machine has 100 percent efficiency, the output work = the input work. That's actually basically what the efficiency of a machine is - output work / input work * 100.
Headache is a common complication of myelography
Myelography may be used when a tumor is suspected
A myelogram is a radiographic study of the spinal cord using contrast medium. The process is known as myelography.
An x ray of the spine
Yes
Some good books about myelography include "Myelography" by J.M. Taveras and R.M. Woodcock, "Neuroradiology: A Core Review" by Varand Ghazikhanian and "Neuroimaging: Anatomy Meets Function" by Johnathan D. Sprinkle. It's also recommended to refer to academic journals and online resources for the most up-to-date information on myelography.
Yes
Headache is a common complication of myelography. It may begin several hours to several days after the examination. The cause is thought to be changes in cerebrospinal fluid pressure, not a reaction to the dye.
CT myelography (a test in which dye is injected into the spine) may demonstrate the cerebrospinal fluid flow between the spinal subarachnoid area and the cyst.
myelography
In most cases, myelography is used after other studies, such as magnetic resonance imaging (MRI) or a computed tomography scan (CT), have not provided enough information to be certain of the diagnosis.
The record of a study of the spinal cord using contrast medium is a myelogram. The process of making the record is known as myelography.
