Push-Pull Electronic Effects in Charge-Transfer Complexes: The Case of N-H and N-Me Lactams. Equilibrium constants and Gibbs free energy changes for 1:1 charge-transfer complexes between I2 or ICl and lactams (N-H and N-Me) were determined in solut... E Firdoussi,Esseffar,Bouab,... ...
mechanical calculations of the rotational barriers in the prototype push-pull ethylene 1,1-diamino-2,2-dicyanoethylene (DADCE) and its non-push-pull analogues diaminofumaronitrile (DAFN) and diaminomaleonitrile (DAMN) have been used quantitatively to assess the influence of the push-pull effect. ...
The meaning of PUSH-PULL is relating to or being an arrangement of two electronic circuit elements (such as transistors) such that an alternating input causes them to send current through a load alternately. How to use push-pull in a sentence.
Similarly, MRP can also be set up as a pull system using electronic kanban or similar methods. Hence, it is entirely feasible to implement pull using MRP. What Is Really the Difference between Push and Pull? All of the definitions above fail to capture the true essence of a pull system....
A push-pull switch employs a coil spring contained in an internal chamber in a housing and surrounding a reduced central portion on a stem passing through the chamber. The spring is interposed between a pair of washers slidably receiving the central portion of the stem for urging the washers ...
