Why Buy a Category B+ Driving License? You'll need an endorsement for Class B in order to drive a vehicle with a trailer that weighs more than 26,000 pounds. It is possible to add an endorsement the CDL class you already hold by taking a new understanding and skills test.

This is only applicable to

Roles of internal salicylate donors (SID) in enhancing activity and stereoselectivity of Ziegler-Natta catalyzed propylene (PP) polymerization were examined using DFT calculations. Five salicylate donors were studied. The chelate mode is the preferred adsorption mode. The linear relationship (R2 = 0.96) between calculated adsorption energies (Eads) of five SIDs and the experimental PP activities was observed. Thus, the SID with the strongest adsorption energy will provide the highest activity in agreement with our previous st
