Durham rule  a definition of criminal responsibility from a federal appeals court case, Durham vs. United States, holding that “an accused is not criminally responsible if his unlawful act was the product of mental disease or mental defect.” In 1972 the same court reversed itself and adopted the American Law Institute Formulation.

M'Naghten rule  a definition of criminal responsibility formulated in 1843 by English judges questioned by the House of Lords as a result of the acquittal of Daniel M'Naghten on grounds of insanity. It holds that “to establish a defense on the ground of insanity, it must be clearly proved that at the time of committing the act the party accused was laboring under such a defect of reason from disease of the mind as not to know the nature and quality of the act he was doing, or, if he did know it, that he did not know that what he was doing was wrong.”

Nägele's rule  (for predicting day of labor) subtract three months from the first day of the last menstruation and add seven days.

rule of nines  a method of estimating the extent of body surface that has been burned in an adult, dividing the body into sections of 9 per cent or multiples of 9 per cent.

Rule of nines.

van't Hoff's rule  the velocity of chemical reactions is increased twofold or more for each rise of 10°C in temperature; generally true only when temperatures approximate those normal for the reaction.

rule (rl)

n.

1. A usual, customary, or generalized course of action or behavior.

2. A generalized statement that describes what is true in most or all cases; a standard.

rule,

a guide for conduct or action.

rule 

1. A guiding principle governing an action or a procedure.

2. A rigid, graduated rod for measuring length.
Javal's rule A relationship that relates corneal astigmatism to the total astigmatism of the eye. It states that

A_t = 1.25A_c − 0.50 axis 90º

where A_t and A_c are the total and corneal astigmatism, respectively. This relationship is relatively accurate in predicting the total astigmatism of the eye when corneal astigmatism is greater than 2D. For smaller amounts of corneal astigmatism, a more appropriate version of Javal's rule is

A_t = 1.0A_c − 0.50 axis 90º

Kestenbaum's rule A procedure designed to estimate the power of the addition needed to read ordinary newsprint (about Jaeger 5 or N7-8) in low vision patients. It consists of dividing the denominator of the Snellen visual acuity fraction by its numer-ator (i.e. 1/Snellen visual acuity). Example: if the Snellen visual acuity is 6/60 (20/200) the power of the add will be +10D, which corresponds to a magnification of 10/4 = 2.5✕. Syn. Kestenbaum's formula.
Knapp's rule See Knapp's law.
Kollner's rule Lesions of the outer retinal layers and changes in the ocular media produce a blue-yellow colour vision defect, whereas lesions of the inner retinal layers, the optic nerve and the visual pathway produce a red-green defect. Examples: age-related maculopathy causes a blue-yellow defect; optic neuritis causes a red-green defect. There are exceptions to this rule, particularly during the evolution of a disease. Syn. Kollner's law.
near point rule A device for measuring the near points of accommodation and convergence. The RAF rule consists of a graduated four-sided bar on which is mounted a movable target holder which can be moved in the median plane of the head. The bar is calibrated in centimetres and dioptres (Fig. R15). See push-up method.
PD rule A ruler calibrated in millimetres used for measuring the interpupillary distance. Some have the zero point in the middle and the gradations on each side to measure two half-distances thus taking into account facial asymmetry. Many PD rules also have facilities for measuring frames (Fig. R16). Syn. pupillometer (although it is an incorrect use of this term, it is frequently used as a synonym).
Prentice's rule See Prentice's law.
Prince's rule A device for determining the location of the near point of accommodation and the amplitude of accommodation. It consists of a ruler scaled in dioptres on one side and in millimetres on the other. One end of the ruler is held against the face and a test card is moved along the ruler towards the eye until a blur is noticed. The amplitude of accommodation in dioptres represents either the ocular accommodation (if the reference point is the cornea) or the spectacle accommodation (if the reference point is the spectacle plane).

Fig. R15 The RAF near point rule

Fig. R16 PD rule. Measurement of the interpupillary distance is made by measuring the distance A between the two corneal images, or B between the edges of the pupils (if both pupils are of the same size), or C between the edges of the limbus

Patient discussion about ruled.

Q. Please tell me what possible changes in body should I look for, as an indication for a positive sign? I had done my home pregnancy test and found it to be negative and I know they are not much reliable….…….soon I will meet doctor. Please tell me what possible changes in body should I look for, as an indication for a positive sign?

A. i think that pregnancy tests are one of the most reliable test there is...it is considered a 99.99% accurate. and you can also do 2-3 tests from different brands in order to minimize that chance also.

Q. Has anyone had any positive weight loss or maintenance from drinking milk?

A. I’m not sure where you got the idea that milk is a diet helper… maybe because drinking a lot of it will give you diarrhea? Milk itself has calories and actually it is highly recommended by alternative Dr. to reduce the amount of milk you eat everyday. And from a good reason. Billion Chinese don’t eat milk and live happy, thin and long life!

Q. The HIV test came back POSITIVE! My very close friend 'Demonte'. One day in December as he was returning from a business trip, his wife met him at the airport with terrible news. During a routine pregnancy check up, her doctor had administered an HIV test along with other blood-work. The HIV test came back POSITIVE! The doctor wanted to begin administering drugs immediately but the cost of these drugs here when compared to their family income was prohibitive. I helped him with some of my savings. He already sold his favorite sentimental car to save his precious wife. Now i want to know is there any NATURAL medicine to cure this? Hope it costs less and available.

A. there are no effective natural remedy for HIV. the medications are very hard ones that try to control the virus from spreading (cannot eliminate it though). no herbal remedy or nutrition change will do that.
