What is the difference between D'alemberts ratio test,raabe's and logarthmic tests?

The series vn converges if vn+1/vn <= r, where r < 1 for all sufficiently large n. \nThis test is known as d'Alembert's test. The corresponding divergence test that S vn diverges, if vn+1/vn >= r, where r >=1 for all sufficiently large n, is trivial. Please see Sl. No 6 in http://kr.cs.ait.ac.th/~radok/math/mat11/chap8.htm#8.181\n\nRaabe's test: http://mathworld.wolfram.com/RaabesTest.html\n\nLogarithmic test is used to test functions like E(1/nlogn)which tend to zero more rapidly than n^(-1), but less rapidly than any power n^(-1-a). Please visit: http://kr.cs.ait.ac.th/~radok/math/mat11/chap9a.htm\n\nI hope u figured the difference.

There was a time when all good civil engineers had to know how to operate a slide rule (which used sliding logarithmic scales to add logs (multiply) and subtract logs (divide), etc.  Civil engineers must be familiar with the fundamentals of all engineering disciplines and would know that the pH of acids and alkalies are logarithmic, the dB of sound decibels are logarithmic and the rickter scale used to measure earthquakes (and to design structures to withstand them) is logarithmic.  They must know the significance (and use) of logs to base 10 and natural logs to base e to work with advanced formulas and calculations.

A normal INR is 1...now every test has a certain error in it, so 1.1 and 1 usually mean the same\n\nIf you are on coumadin, then your INR increases...\n\ntarget INR depends on the medical condition for which your are anticoagulated for. Atrial fibrilation is usually treated with a lower INR than a metal valve

Yong's modulus is a measure of stiffnes = tensile stress / tensile strain\n\n"Poisson's ratio is the ratio of the relative contraction strain, or transverse strain (normal to the applied load), divided by the relative extension strain (in the direction of the applied load)." (wiki)\n\n"Datum geometry is geometry that exists only for reference purposes and has no mass, no color, no material properties"\n( http://216.118.118.21/dbbp/cadbikes/howto_1.htm )

If you have a quantitative dependent variable and a nominal independent variable, then the one-way ANOVA test is appropriate.\n\nIf you have nominal dependent and independent variables, then a chi-square test for independence is appropriate.

Would you like to know the disadvantages or the differences? Ok I'll try to explain a little on both.\n\nDIFFERENCE:\n\nThe Richter scale defines an earthquake's "magnitude". It is a measure of how strong an earthquake is - depending on the energy released at its source, called the focus, where the initial break or slippage in the rocks occurs. Hence this is a scientific and objective measure, calculated from amplitudes of seismic waves.\n\nThe Mercalli scale describes the "intensity". It is based on an earthquake's effect on people, structures, etc. It measures the damage on society - in other words, how intense it was for a particular area. This means it is not concerned about the earthquake source, simply on the area that is being described, and is therefore a subjective measure.\n\nDISADVANTAGES:\n\nWell, there aren't REAL disadvantages in using either scale, in fact, both should be used in order to evaluate a certain earthquake. The disadvantages lie in using only one of these, or not knowing which is which! But if you're reading the news, they're easy to distinguish: Richter is in Hindu-Arabic numerals (normal numbers) so you get 7 or 8.5, etc. Mercalli is denoted in Roman numerals, like VII, and no decimals of course.\n\nJust bear in mind that the Richter Magnitude is about the earthquake source itself, and the Mercalli Intensity depending on the area being considered. For example, a very strong earthquake in the middle of an uninhabited wasteland would register high on the Richter but low on the Mercalli, simply because there were no people or structures to affect. If a weak earthquake occured right in an area with many people having unstable houses, then this would cause a lot of damage or death and therefore register high on the Mercalli, although low on the Richter.\n\nHope this helps :)

The sial has a lighter density (2700 - 2800 kg/m3) than the sima, which is due to increased amounts of aluminium, and decreased amounts of iron and magnesium. At the base of the sial it grades into the basalts of the sima. The dividing line, called the Conrad discontinuity, has been arbitrarily set at a mean density of 2800 kg/m3.

Yes there are different versians of it. Its the same test but they have a questionaire bank of about 200 questions I believe. Try going to this website to find out more. \n\nhttp://usmilitary.about.com/cs/joiningup/a/dlab_2.htm\n\nHope it helps.

First of all you should give us more info, like what exactly is the elimination test, concentrations, conditions and if you know the pH of the final solution or the final concentration of acetic acid.\n\nA very rough explanation based on the limited info, would be that HF is a much stronger acid than HPO4-2, so in an acidic environment it manages to dissociate much better, giving the conjugate base or if you prefer the conjugate base F- is much weaker than PO4-3 so PO4-3 will steal away the H+ from the acetic acid. Thus it is possible that in the acidified medium you have most of the phosphate in the form of HPO4-2, and the concentration of PO4-3 is too low to lead to precipitation.\nOn the other hand, although CaF2 is much more soluble, most of F- will remain as such and thus its concentration might be high enough to promote precipitation.

A hydrostatic test is the normal way in which a gas pressure vessel such as a gas cylinder or a boiler is checked for leaks or flaws. Testing is very important because such containers can explode if they fail when containing compressed gas. Hydrostatic testing is also a way in which leaks can be found in lower pressure vessels such as pipelines and plumbing.\n\nThe vessel is filled with a nearly incompressible liquid - usually water or oil - and examined for leaks or permanent changes in shape. The test pressure is always considerably more than the operating pressure to give a margin for safety, typically 150% of the operating pressure. Water is commonly used because it is almost incompressible, so will only expand by a very small amount should the vessel split.

I hope you didn't use the other answer for your homework because those are not density values. They are mass values for a specific volume. There is a big difference. \n\nThe density of gneiss is:  2.6 - 2.9

Are you trying to perform a destructive or a non-destructive test. The formulas for both are different, and it would be difficult to advise without knowing...

arithematic is related to more of your mathematical skills.whereas quant. aptitude is related to check your sharpness of mind and application of knowledge as well.

Here is one of the tests you are talking about.  I hope this helps.
