When the first stage of the reaction (addition of the electrophile) is rate-determining, the rate responds powerfully to electron release to the reaction centre, and this factor determines selectively the orientation of initial attack with respect to the double bond.
These variations in electronegativity for aromatic compounds can interfere with the orientation of hydroxyl radical attack, which is electrophilic in nature [ 29].
In RNase T1, correct orientation of the substrate for inline attack is achieved by "sandwiching" of the guanine base between Y42 and Y45, similar to the stacking of Y87 of RelE with the second base of the A site codon.
This maximal pressure force shifted towards hand's leading edge; this is when the swimmer altered orientation of the hand, that is, the angle of attack and sweepback angle.
It had been made clear by Ms. Allred beforehand there were subjects they would not discuss: Ms. Martin's recent relationship with her husband, the question of Ms. Martin's sexual orientation, the attack.
Four design variables are used in the optimization process to control the fluid flow angle of attack, as well as position and orientation of a leading-edge slat.
The algorithm is applied to the design of a multi-element trawl-door, involving four design variables controlling the angle of attack and the slat position and orientation.
The orientation of the wounds hints that the attack most likely came from below; in the paper, Zammit and Kear hypothesize that the wound might represent a "restraining bite" left when the other ichthyosaur "attempted to neutralize the threat of a counter attack by clamping onto and forcing aside [the victim's] elongated jaws".
"This is a reminder that attacks on any American — regardless of race, religion, or sexual orientation — is an attack on all of us and on the fundamental values of equality and dignity that help us as a country".
"This is a sobering reminder that attacks on any American, regardless of race, ethnicity, religion or sexual orientation, is an attack on all of us, and the fundamental values of equality and dignity that define us as a country," he said.
A super PAC trying to draft Milwaukee County Sheriff David Clarke for a Senate bid is attacking the sexual orientation of Sen. Tammy Baldwin (D-Wis)., who is up for reelection in 2018.
