Variables that determine the price of one yard of concrete include preparing the subbase, grading, reinforcing, forms and finishing, and the concrete itself, as of 2015. The average price for ready-mix concrete was $93 per cubic yard nationwide in 2013.
From Wikipedia, the free encyclopedia. 12-Hydroxyeicosatetraenoic acid (12-HETE) is a derivative of the 20 carbon polyunsaturated fatty acid, arachidonic acid, containing a Hydroxyl residue at carbon 12 and a 5 Z, 8Z ,10 E ,14 Z Cisâtrans isomerism configuration (Z=cis, E=trans) in its four double bonds.n humans, Arachidonate 12-lipoxygenase (12-LO, 12-LOX, ALO12, or platelet type 12-lipoxygenase) is encoded by the ALOX12 gene and expressed primarily in platelets and skin.
Lactic acid is an organic compound with the formula CH3CH(OH)CO2H. In its solid state, it is white and water-soluble. In its liquid state, it is clear. It is produced both naturally and synthetically. With a hydroxyl group adjacent to the carboxyl group, lactic acid is classified as an alpha-hydroxy acid (AHA). In the form of its conjugate base called lactate, it plays a role in several biochemical processes. In solution, it can ionize a proton from the carboxyl group, producing the lactate ion CH. 3CH(OH)COâ. 2. Compared to acetic acid, its pKa is 1 unit less, meaning lactic acid deprotonates ten times more easily than acetic acid does.
