plz describe 'the crystal in urine'?
462786
The crystal in urine can appear because of many factors, such as: over-saturated concentration of its parts, pH, crystallization inhibitors etc.\nThere are a lot of crystal types:\n1. of uric acid (in acid urine, it helps convert uric salts, soluble, in uric acid, insoluble); with a rhomboid shape, they could appear in patients with gout.\n2. of calcium phosphate or calcium oxide: the calcium oxide ones don't depend on the urine pH, meanwhile the calcium phosphate crystals grow in an alkaline urine. Risk factors: low ingest of liquids and calcium, high ingest of salt and proteins.\n3. crystals of magnesium phosphate: when the urine's pH increases, the solubility of the phosphate reduces

The chalky-white paste called urate (made of uric-acid crystals) is a byproduct of bird kidneys. What you actually see is the color of the whitish crystals. Swimming in urate is a chunk of stool (solid waste). This piece is usually hard and worm-like, and gets its color from the bird's diet. Hues range from greenish for birds who feed on plant seeds and green vegetables, to brownish for brown birdseed, and reddish for strawberries. For shrimp-eating seabirds, it's pink!\nTo top it all off, bird poop contains a tiny sprinkle of urine. Why so little? "Aside from the ostrich, birds don't have bladders and can't carry a lot of water around. They'd be too heavy to fly," explains ornithologist (bird expert) Jerome Jackson at Florida Gulf Coast University. (By the way, the ostrich can't fly.)\n\nThink bird poop is just waste? Think again. Veterinarians see it as an indicator of bird health. Abnormal colors like red urine and urate may be signs of internal bleeding. Brown urate may signal lead poisoning, and green or yellow urate may mean liver disease. Colorful indeed!

hard to say. i found lots of things in the desert. my husband is a geologist. if you mail me a picture, i will have him look at it.\nthere is lot of crystal stuff in egyptian deserts, most are worthless unless you enjoy it as decoration in your house. does it has a greenish tone in the bottom of the crystals? i have lots of them. it depends also where you found it. if it was near a roman settlement, it could be ancient glass, but if it scratch glass now, i doubt it. i found lots of this, but not this big of a piece, that would be uncommon. tell me more about it, maybe i can help you.\n\nsend me a picture...susuegypt@hotmail.com

The question is not clear.  Are you asking what a crystal is?  Are you asking what the different crystal structures are?  Are you asking for the characteristics of crystals in general?

Speed is a slang word for amphetamines.  On the street crystal meth refers to a highly refined meth-amphetamine, where as "crank" is usually dirty and gross.  Real crystal meth looks like broken glass, where as "crank" is a white or yellowish (sometimes even brownish) powder.\n\nThis is the worst drug in the history of man, stop using it now.  Very very bad stuff, all of it from crystal to the yucky brown stuff!\n\nHow could you use this drug for 4 years and not know the difference, or what you were doing?

Piss shiver, aka post-micturition convulsion syndrome.\nYes, it even has a scientific name!\n\nStraight Dope deals with most theories (which are all silly, sick or both):\nhttp://www.straightdope.com/classics/a4_225.html\n\nThis is the best answer I found so far:\nhttp://www.madsci.org/posts/archives/jan2000/947350899.An.r.html\nDr. Swanson rules!\n\nIn essence, keeping it in requires adrenaline, which you feel as shivering after letting it go.

Every quarter, I run a urine lab in my introductory Human biology course.\nAfter everyone gets over feeling uncomfortable by having others see their\nurine, it turns out to be one of the most popular labs we do.\nInterestingly, I usually get at least one female asking me the same\nquestion--quite confidentially. "Why is it that male urine seems to have\nmore bubbles that female urine?"\n\nMy off-the-top-of-my-head response has always been in the method of\ncollection. I suggest that males, perhaps because of greater force, or\ndistance, are able to "blast" the sample and thus create more froth. A\nlogical hypothesis, I thought, but never tested.\n\nI could not think of a very accurate way to test the hypothesis, and still\nmaintain the high standards of our institution and still retain my job. But\nlast week, I figured out a way.\n\nWhen the student returned to the lab with their samples in hand, I asked\nthree males and three females, if I might have a third of a test tube of\ntheir finest for a test I was going to run. They agreed, and the only\nidentifying marks were the classic male and female symbols on the test\ntubes. Each test tube was covered with parafilm, and then each was shaken\n(not stirred) for five times (or 5 "shakes").\n\nAll three of the male samples created 2-4 cm. "heads," while all three\nfemale samples could only muster about 0.5 cm. worth of effort. After\nstanding for 1 hour, the male samples still had about 1 cm. of foam, while\nthe female samples were entirely bubbleless.\n\nObviously, the bubble factor of urine is not due to the method of\ncollection, but shows a definite dimorphic difference. I realize that the\nsample size was small and the experiment lacked the proper elegance to be\nrecorded in a journal. Still, while trying hard not to appear sexist, it\ndoes appear that males are better bubble-makers than females.

Urine is normally clear. [A special test] determines the cloudiness of urine, also called opacity or turbidity. Bacteria, blood, sperm, crystals, or mucus can make urine appear cloudy\n\nMake sure to drink plenty of water and if you're still concerned, see your doctor just to be on the safe side.

It is a method used to separate a solid organic substance from other solid impurities.\n-The impure solid is dissolved in a suitable hot solvent (to dissolve only the organic solid, not the impurites)\n-The impurities that did not dissolve in the solvent are removed by filtration.\n-The filtrate is left to cool, whereby any soluble impurities remain in the solution and the pure product crystallizes out.\n-The crystals formed are filtered using a vaccum filtration apparatus to help them to dry out quickly.\n-The crystals are washed with the cold solvent to remove impurities on the surface of the crystals.\n-Final drying of the crystals is carried out in a desicator at low pressure.

The yellow is from the breakdown of old blood cells.  It is a compound called urobilirubin and your kidneys pee it out.  If your urine is clear, it is not necessarily a sign that you are well hydrated, but a sign that there is not much urobilirubin in the urine.  Most of the time it's because the urine is dilute by a lot of water, though.
