  2. Hydrodynamical helicity - Wikipedia

    en.wikipedia.org/wiki/Hydrodynamical_helicity

    Helicity is a pseudo-scalar quantity: it changes sign under change from a right-handed to a left-handed frame of reference; it can be considered as a measure of the handedness (or chirality) of the flow. Helicity is one of the four known integral invariants of the Euler equations; the other three are energy, momentum and angular momentum.

  3. Phosphatidylethanol - Wikipedia

    en.wikipedia.org/wiki/Phosphatidylethanol

    [5] [6] An increase of alcohol intake by ~20 g ethanol/day will raise the PEth 16:0/18:1 concentration by ~0.10 μmol/L, and vice versa if the alcohol consumption has decreased. However, it has been demonstrated that there can be significant inter-personal variation, leading to potential misclassification between moderate and heavy drinkers. [ 7 ]

    Many people with the disorder find themselves experiencing difficulties with fulfilling work, caregiving and daily life responsibilities due to their alcohol intake.

  5. Pharmacology of ethanol - Wikipedia

    en.wikipedia.org/wiki/Pharmacology_of_ethanol

    The reinforcing effects of alcohol consumption are mediated by acetaldehyde generated by catalase and other oxidizing enzymes such as cytochrome P-4502E1 in the brain. [60] Although acetaldehyde has been associated with some of the adverse and toxic effects of ethanol, it appears to play a central role in the activation of the mesolimbic ...

    The results of this study compared patterns of alcohol use from 2012-2013 to use in 2001-2002 and found that the rate of alcohol use rose more than 11%; the rate of high-risk drinking increased ...

  7. Helicity (particle physics) - Wikipedia

    en.wikipedia.org/wiki/Helicity_(particle_physics)

    The helicity of a particle is positive (" right-handed") if the direction of its spin is the same as the direction of its motion and negative ("left-handed") if opposite. Helicity is conserved. [1] That is, the helicity commutes with the Hamiltonian, and thus, in the absence of external forces, is time-invariant. It is also rotationally ...

  8. Flow distribution in manifolds - Wikipedia

    en.wikipedia.org/wiki/Flow_distribution_in_manifolds

    Thus the velocities should be equal in two outlets or the flow rates should be equal according to the assumptions. Obviously this disobeys our observations. Our observations show that the greater the velocity (or momentum), the more fluid fraction through the straight direction. Only under very slow laminar flow, Q 2 may be equal to Q 3. Fig. 3.

  9. Beer measurement - Wikipedia

    en.wikipedia.org/wiki/Beer_measurement

    A basic formula [4] to calculate beer strength based on the difference between the original and final SG is: A B V = 131.25 ( O G − F G ) {\displaystyle ABV=131.25(OG-FG)} The formula below [ 5 ] is an alternate equation which provides more accurate estimates at higher alcohol percentages (it is typically used for beers above 6 or 7%).
