a three day old neonate was referred to our department with a problem of a sternal cleft. sternal clefts are often associated with a myriad of other abnormalities ranging from mild to severe. we present our experience with such a problem, and review the current literature concerning it.

Conventional metal curtain walls have used aluminum frames to support the fireproof boards of spandrels. Since melts at about 660°C, board may fall off in event a fire, causing fire spread upper floors. Therefore, we developed wall supported by frame, and confirmed its performance (prevention falling off) for 2 hours experiments. We also composite insulated steel beams columns using these board...

Introduction: Reconstruction of chest wall defects remains a very challenging issue and often requires prosthetic repair to prevent flail chest and paradoxical breathing. Case Report: We report a case of chest wall reconstruction following resection of a long standing, massive, well differentiated, primary chondrosarcoma of the sternum which was involving the entire body of sternum and adjoinin...

We derive the equations of motionof a domain wall in a thin-film magnet coupled to the surface states of a topological insulator, in the presence of both an electric field along the domain wall and a magnetic field perpendicular to the junction. We show how the electric field acts as a chirality stabilizer holding off the appearance of Walker breakdown and enhancing the terminal velocity of the...

We investigate the scattering of fermions off walls in the presence of a magnetic field. We consider both the bubble wall and the kink domain wall. By solving the Dirac equation for fermions in the presence of a domain wall in an external magnetic field, we investigate the dependence on the magnetic field of the transmission and reflection coefficients. In the case of kink domain wall, we also ...
