In addition, the backbone of carbohydrate molecules is covered by many copies of the same functional group, a hydroxyl (OH) group, which made it difficult to attach different groups at specific positions along the ring.
Very frequently, power and velocity assessed during the F-V curves are measured by means of linear transducers attached to the bar, making it difficult to identify if athletes applied more force at altitude or if the results are produced by lower resistance to movement.
It works on the same part of the brain as opiate receptors, but instead of attaching onto these receptors, they bounce off, she claims, making it difficult to get physically addicted.
EDC coupling can sometimes give intermediates which easily aggregate and can also make it difficult to control the number of molecules attached to the surface of a single QD.
In the case of odontocetes, the thin bony membrane and the attached malleus could be expected to vibrate, even though its complexity makes it difficult to envision without vibrational analysis.
