polarization

 [po″lar-ĭ-za´shun]
1. the presence or absence of polarity.
2. the production of that condition in light in which its vibrations are parallel to each other in one plane or in circles and ellipses.
3. the separation of electric charge so that there is directionality of flow, as in a body, cell, atom, or molecule.

po·lar·i·za·tion

(pō'lăr-i-zā'shŭn),
1. In electricity, coating of an electrode with a thick layer of hydrogen bubbles, with the result that the flow of current is weakened or arrested.
2. A change effected in a ray of light passing through certain media, whereby the transverse vibrations occur in one plane only, instead of in all planes as in an ordinary light ray.
3. Development of differences in potential between two points in living tissues, as between the inside and outside of a cell wall.

polarization

/po·lar·iza·tion/ (po″lar-ĭ-za´shun)
1. the presence or establishment of polarity.
2. the production of that condition in light in which its vibrations take place all in one plane, or in circles and ellipses.
3. the process of producing a relative separation of positive and negative charges, such as in a body, cell, molecule, or atom.

polarization

[pō′lərīzā′shən]
Etymology: L, polus + Gk, izein, to cause
the concentration, within a population or group, of members' interests, beliefs, and allegiances around two conflicting positions.

polarization

Cardiac pacing The condition of an electrode in which its electrical potential differs from an equilibrium potential–ie, no current flow

polarization

the act of changing an ordinary light beam consisting of billions of wavetrains each vibrating in a different direction, to a beam in which only those wavetrains vibrating in a particular plane are allowed to continue in the beam which is then less bright.

Light from the sun is scattered by molecules in the upper atmosphere in such a way as to result in light arriving at the earth's surface being partially polarized. The extent of polarization at any point depends on the position of the sun, so there is a pattern of polarization of the sky for any particular position of the sun. Bees, and probably many other arthropods, are capable of navigating by this pattern when the sun is obscured, so long as some blue sky can be seen (see NAVIGATION). Polarization can be brought about by naturally occurring crystals such as calcite, or by Polaroid sheets.

polarization,

n a process wherein the direction of electromagnetic radiation or light is limited to a particular plane.

polarization

the production of that condition in light in which its vibrations are parallel to each other in one plane, or in circles and ellipses.

Patient discussion about polarization

Q. Can bi-polar be treated with acupuncture and Chinese medicine? Any help would be appreciated. I am a bipolar. I always get side effects from the meds being prescribed by my psychiatrist. I feel better one day but the very next day I feel moody and have outbursts even on meds as if I am not after them. I wish to follow a different system of treatment. Can bi-polar be treated with acupuncture and Chinese medicine? Any help would be appreciated.

A. Do a lot of research before coming off your meds. You should consult your doctor about how to come off your meds safely. First arm yourself with information about what the effective treatments are and how to get those treatments.

Q. My brother-in-law named Jacob has bi-polar schizophrenia; please help us by giving some solution for this… My brother-in-law named Jacob has bi-polar schizophrenia; he is currently on his medication and takes them faithfully in a positive mood. We have a hard time communicating with each other and it's destroying our marriage, please help us by giving some solution for this…

Q. Is spending money irresponsibely a sign of impending manic attack? My 32 years-old husband is known to have bi-polar disorder, but for the last ten years he has been on lithium treatment and had no attacks. Last week he bought some very expensive things to our home, without asking me (we usually discuss these things before we do anything). Does this mean he’s getting a new manic attack? Other than that purchase everything else is normal, and he appears and behaves as usual. I don’t want to take him for the psychiatrist just for spending some money.

A. Spending money is not a unique character of bi-polar people... Maybe it was a bit less calculated action. If he has manic attack, usually there'll be more things that would tell you about it.
