Where shall I get resources on X-ray diffraction characteristic pattern of urinary calculi?
Q. I wana analyse urinary stone as part of my research. The laboratory where I want to analyse the stones has no software to decipher the x-ray diffration patterns to their equvalent chemical composition of the common urinary calculi/uroliths. Any body who can help in providing how to intepret x-ray diffraction pattern of common urinary stones

Can rice causes renal calculi?
Q. My question about rice's chemical properties, some of my friends says that rice contains only sugar while other says that it contains sugar and some salts as well. My uncle has renal calculi, He usually takes rice in his food, so my question is about rice whether its harmful for my uncle or not. Thanks In Advance

Calculi of the tonsils?
Q. I know that this is a somewhat common problem... but I get calculi of the tonsils, which is when little food particles get trapped in the back of my mouth in the deep crevices of my tonsils. It causes bad breath and it is very uncomfortable. Anyone else suffer from this have any tips on how to deal with the problem or remove the debris? So far for me it's been a small flashlight and a Q-tip.
Asked by Nicole H - Thu Nov 8 06:40:42 2007 - - 2 Answers - 0 Comments
A. I get this, it is horrible and uncomfortable. I found the best thing to do is to gargle soluble aspirin repeatedly until it gets dislodged. (Aspirin also has anti-inflammatory properties so this may help too), failing that I would try gargling with mouthwash (at least it'll help the breath!!) Another thing that has helped is eating coarse food like crisps. I can't tolerate the Q tip down the throat method - makes me gag!!

What is a good Multivariable calculus textbook at the university level?
Q. Right now, my multivariable calculus class uses "Vector Calculus" by Marsden and Tromba but I really dislike how this textbook is written. It is obscure, is not good at explaining it's examples and often times I feel like it isn't comprehensive enough. Could you guys recommend to me a very good Multivariable Calculus textbook that I could read and then understand this material? Thanks in advance!

A. Calculus, per se, is NOT a prerequisite for either entry into or completion of the US Naval Flight Officer program. HOWEVER...depending on your friend's desires, a familiarity with calculus will certainly make easier the basic mathematics that ARE required for completion of the program...AND...if he/she wishes, after flight school, to go to Test Pilot School or become an Aeronautical Engineer and then enter the astronaut program, then yes, I would say certainly take as much math, including calculus, that you can fit into your program, because Test Pilot School is practically ALL advanced mathematics and the competition to enter the Astronaut program is very intense, and a familiarity with advanced mathematics is pretty much a requirement.

I would go to the doc for pain meds, so to not sugar coat things, you will be needing pain killers. To avoid future stones you will need to change your diet and drink a lot more water for hydration. Restrict your oxalate intake. Good luck i commend you on going through this as this is a very painful dilemma.

A. Well... as for your GPA that is really bad. Adjusted GPA's are not counted anywhere. Meaning, even if you retake the course and get a C, you will always carry that D with you, everywhere. Best of luck. Also, Look at your curriculum guide. A grade of a D is usually not a passing grade to advance in your degree plan at some schools. Some or Most require C's or better.

A. At least an 83. Im halfway through calc 3, myself, and Im managing without a calculator at all. I rent an 83 from the school whenever I have a test. Edima, below, is right. You dont really need a calculator for higher calculus. Most of calculus is conceptual. And manipulation of symbols on paper. There is very little computational work that cant be done on paper, in the head. The only time you truly need a calculator is to evaluate trig functions or logarithms; and more than likely, the answers will "coincidentally" be trivial to evaluate, something you should know in the head anyway.

A. Depends on what you're doing with your bachelors in psychology. If you wish to pursue a masters or doctorate degree, working in math will be pretty critical because you'll be dealing with statistics and probability and population samples and you have to show you can do it all to get into graduate school. Mostly you'll be working with statistics though more than calculus in psychology. But calculus doesn't hurt and rounds out the education a bit if you wish to. A piece of free advice? Take your statistics early on and REALLY pay attention to it - it really changes how you process your information as you pursue your psyche degree and analyze and assess info you'll be working with.

A. I taught Calculus A, B and C, each for one term, in a UC campus. AP Calculus AB = Calculus A AP Calculus BC = Calculus B Many of my students in Calculus C passed AP Calculus BC in high school.
