Answer version1 (read the comments, I leave v1 for the those who can make the same assumptions in the future) To answer the question we should clarify some general concepts and processes mentioned it the clause: EMG is performed by means of direct placement of the electrode (the are two types here - surface-EMG and needle-EMG) on/into the skeletal ...

Birds, like amphibians, have a third eyelid (the nicitating membrane) that helps them keeps their eyes moistened and allows them to better visualize at high speeds (or, for amphibians, underwater). The glands in birds' eyes allow them to secrete a fluid that is more resistant to evaporation than tears. The membrane also acts as a 'windshield wiper,' with ...

Very basically, what they've done in the paper was incubate different DNA sequences with histone octamers which were then separated on a gel. From this they could measure the ratio between nucleosomal and free DNA, which represents an equilibrium constant. This can then be expressed as a change in free energy ($\Delta G=-RTln(K)$), which is what the table ...

Birds have a body part known as the nicitating membrane otherwise known as the "third eyelid". This part has become vestigial in humans, where it remains as the plica semilunaris. This image of a masked lapwing clearly shows its nicitating membrane in action, where it covers the eye in a horizontal motion. This is analogous to blinking in humans, and the ...

Citing your source would help to answer. In order to test an elastic modulus, you need to apply some non-zero strain. If the strain is infinitesimal, then compression and stretch modulus will be equal. But if it is finite, then there can be a difference due to the structure of the material. In bone, I believe porosity will provide most of the dissymetry ...

One important notion in DNA topology is the linking number ($Lk$) which is the sum of right-handed twisting # and left-handed writhing # ($Tw+Wr$). Say the $Lk = x$ for relaxed DNA. If $Lk<x$ then you have negative supercoiling while positive supercoiling happens when $Lk>x$. The higher the $Lk$ value the higher the helical energy of the DNA and the ...
