Reverse hammering is the method applied during nailing of transverse long bone fracture to decrease gap between ends ensure healing. This study aims asses effectiveness reverse on union in as well possible complications this method. Seventy six patients with (femur, tibia, & humerus) treated close reduction and internal fixation interlocking were enrolled a prospective conducted at departme...

This paper describes the visualization of defect regions in a structure via hammering test that employs level set type topology optimization based on concept phase-field method. In this study, residual between calculated displacement and observed is defined as performance function, with identification problem being formulated adjoint variable finite element methods. Numerical experiments were p...

Monopile foundations contain welding residual stresses and are widely used in industry to support offshore wind turbines (OWTs). The monopiles subjected hammering loads during installation cyclic operation, therefore the influence of stress redistribution as a result fatigue cycles must be evaluated these structures. existing empirical models predict presence loading conditions strongly depende...

It is extremely unusual for primary pulmonary lymphoma, an uncommon occurrence in any form, to be of T-cell origin and manifest as endobronchial lesion. Each these characteristics rare individually, so cases that combine them are exceptional. We report a patient whom anaplastic large cell neoplasm, presented with obstruction the left upper lobe bronchus, resulting atelectasis creating radiograp...

In this study, experiments were conducted to provide validation data for numerical simulations. Model tests in a 2D wave flume at the Korea Research Institute of Ships and Ocean Engineering (KRISO). A series hammering two flat plates with different lengths under dry partially wet conditions performed investigate vibrating frequencies each mode. Thereafter, breaking using focusing method. Repeti...
