Chelsea P.T.O.s are designed and built to match a vehicle’s transmission. The gears of a P.T.O. are of the same quality as the transmission’s gears. Nasara aiki ya dogara dace jaddadawa da kafuwa.

The anomeric effect of a heterospiral ring means that two electron-positive atoms or lone pairs of electrons in the conformation are in the opposite direction to reduce the dipole moment of the molecule and reduce the intramolecular energy. In 1968, the Descotes research team first proposed an anomeric effect. When they studied the bicyclic acetal, they found that the two compounds in the figure below contained 57% of the cis isomer and 43% of the trans isomer in the equilibrium mixture at 80 C. The cis isomer ratio trans The isomer was stable with an energy difference of 0.71 kJ/mol. Because of the anomeric effect of the cis isomer, the trans isomer has no such effect.
