Is intestinal metaplasia dangerous?
diagnosis ulcerated gastric hyperplastic poly with focal intestinal metaplasia with lymphoplasmactic infiltrate also gastric oxyntic-type mucosa with lymphoid aggregate what does this mean
Why is concave lens called a negative lens?
Concave lens is called a negative lens because it has a negative focal length.
What is a calibrated focal length?
A calibrated focal length is an adjusted value of the equivalent focal length on a camera, so as to equalize the positive and negative values of distortion over a field.
The distance between a mirror and its focal point is called the?
Focal length, positive number with a concave mirror, negative for a convex mirror.
Length of a lens is the distance from the center of the lens to its principal focus?
It is called the focal length. It is equal to 1/2 times r, and is positive on concave mirrors and negative on convex mirrors.
What is the positive lens is the same as?
The focal point F and focal length f of a positive (convex) lens, a negative (concave) lens, a concave mirror, and a convex mirror. The focal length of an optical system is a measure of how strongly the system converges or diverges light.
How do you find the power of lenses using focal lengths?
Power (F)= 1/focal length (f) focal length f, is measured in meters the power, F, is in dioptres (D) In converging or convex lenses the power is positive In diverging or concave lenses, the power is negative :)
Should adults with cortical dysplasia not have children?
Although Cortical Dysplasias can cause Epilepsy in some, it doesn't cause it in everyone. The brain has an amazing ability to re-wire itself after injury. It is possible that the brain can function without misfiring and having seizures. I have a 15 year old son with Focal Cortical Dysplasia and so far he has not had a seizure, he is above average intelligence, wrestles, plays guite, draws, bikes, plays full contact Karate. I think there is much more to the brain that needs to be studied. Also, many people don't get MRI's so how do we know if more people don't have this condition? Unless an MRI is done or an autopsy, we will never know how many people have Focal Cortical Dysplasia without symptom,s or seizures.
What is the difference between the focus of concave and convex mirror?
the focal point of a concave mirror is positive while a convex is negative
What are diverging and converging lenses?
Lenses enable individuals to view objects. A Converging lens has a positive focal length, which facilitates the convergence of the exiting rays. While, diverging lenses have a negative focal length, which facilitates the divergence of the exiting rays.
What is a negative lens is the same as?
If the lens equation yields a negative image distance, then the image is a virtual image on the same side of the lens as the object. If it yields a negative focal length, then the lens is a diverging lens rather than the converging lens in the illustration.
What is the prefix for focal?
the prefix for focal is infocals
