Determining a " country of origin " is thus much more difficult than determining other aspects of a gem ( such as cut, clarity etc.

Determining the presence of both parts of this definition is not always straightforward, as hypoglycemic symptoms and effects are vague and can be produced by other conditions ; people with recurrently low glucose levels can lose their threshold symptoms so that severe neuroglycopenic impairment can occur without much warning, and many measurement methods ( especially glucose meters ) are imprecise at low levels.

Determining how many people died in these massacres overall is difficult.

Determining a precise value for a particular knot is difficult because many factors can affect a knot efficiency test: the type of fiber, the style of rope, the size of rope, whether it is wet or dry, how the knot is dressed before loading, how rapidly it is loaded, whether the knot is repeatedly loaded, and so on.

Determining whether a particular event or proceeding constitutes the commencement of adversarial criminal proceedings requires both an examination of the rules of criminal procedure for the jurisdiction in which the crime is charged and the Supreme Courts cases dealing with the issue of when formal prosecution begins.

Determining the distances to astronomical objects is crucial to understanding them, but the vast majority of objects are too far away for their distances to be directly determined.

Determining if the customer is likely to return to reclaim an item is a subjective decision, and wily customers may attempt to persuade the pawnshop owner that the item in question is important to them (" that necklace belonged to my grandmother, so I will certainly return for it "), and they will claim that they will return to recover it.

Determining the grazing angle with respect to a planar surface is trivial, but the computation for almost any other surface is significantly more difficult.

Determining the agent is especially important because women may have more than one infection, or have symptoms that overlap those of another infection, which dictates different treatment processes to cure the infection.

Determining mass is even more difficult, because little evidence of soft tissues survives in the fossil record.

Determining a suitable classifier for a given problem is however still more an art than a science.

Determining whether socioeconomic or political factors are more important in explaining government action is a familiar theme.

Determining the appropriate treatment for noncyclical breast pain is more difficult, not only because it is hard to pinpoint where the pain is coming from, but also because the pain may not have hormonal causes and very often does not respond to hormonal treatment.

Determining the prime factors of a number is an example of a problem frequently used to ensure cryptographic security in encryption systems ; this problem is believed to require super-polynomial time in the number of digits-it is relatively easy to construct a problem that would take longer than the known age of the Universe to solve on current computers using current algorithms.

Determining the achromatic number is NP-hard ; determining if it is greater than a given number is NP-complete, as shown by Yannakakis and Gavril in 1978 by transformation from the minimum maximal matching problem.

Determining the new territory too large to administer as one unit, Britain divided its new southeastern acquisitions into two new colonies separated by the Apalachicola River: East Florida, with its capital in the old Spanish city of St. Augustine, and West Florida, with its capital at Pensacola.

Determining whether there is an isomorphism between two graphs is also an important problem in computational complexity theory ; see graph isomorphism problem.

Determining which amino acid forms the N-terminus of a peptide chain is useful for two reasons: to aid the ordering of individual peptide fragments ' sequences into a whole chain, and because the first round of Edman degradation is often contaminated by impurities and therefore does not give an accurate determination of the N-terminal amino acid.

Determining a precise location in the sky was complicated by the fact that the Big Ear telescope used two feed horns to search for signals, each pointing to a slightly different direction in the sky following Earth's rotation ; the Wow!

Determining your location in 2D space requires two measurements or angle or range-two angle measurements, two distance measurements, or one angle and one distance.

Determining which two cast members will be sent into the elimination round frequently leads to drama and contestants playing the game dirty.

Determining that a risk has been reduced to ALARP involves an assessment of the risk to be avoided, of the sacrifice ( in money, time and trouble ) involved in taking measures to avoid that risk, and a comparison of the two.

Determining the strain energy within a molecule requires knowledge of the expected internal energy without the strain.

Now we consider the set of all normal sets, R. Determining whether R is normal or abnormal is impossible: If R were a normal set, it would be contained in the set of normal sets ( itself ), and therefore be abnormal ; and if R were abnormal, it would not be contained in the set of all normal sets ( itself ), and therefore be normal.

Determining precisely how many people died is next to impossible as accurate records were not kept.
