theoretical study of the electronic structure, and nonlinear optical properties (nlo) analysis of 12-crown-4were done using density functional theory (dft) evaluations at the b3lyp/6-311g (d,p) level of theory. the optimized structure is nonlinear compound as indicated from the dihedral angles were presented. the calculated ehomo and elumo energies of 12-crown-4 (12cn4) can be used to explain t...

conclusions the use of variable-angle locking plates in treating unstable distal end radius fractures is associated with excellent to good functional outcomes with minimal complications. objectives this study aimed to evaluate the functional and radiological outcomes in unstable distal end radius fractures treated with variable-angle locking plates. patients and methods we reviewed 23 unstable ...
