While psychotherapy is generally effective, outcomes can vary significantly across patients, even when treated by the same therapist. This study employed a mixed-methods design to examine early indicators of treatment success by analyzing contrasting outcomes within individual therapists’ caseloads....

High-performance liquid chromatography (HPLC) was employed to determine drug release rates based on emamectin benzoate concentrations in the medium. Release kinetics equations were used to fit the drug release behavior. The effects of particle size and release medium pH on the release rate were also...

Conventional bolts frequently fail under large deformations due to stress concentration in soft rock tunnels. In contrast, yielding bolts incorporate energy-absorbing mechanisms to sustain controlled plastic deformation. This study employed FLAC3D to numerically investigate the pull-out, shear, and...
