Theory and applications of the Doppler effect
, 1993 This paper describes the manner in which sound and electromagnetic waves are affected by the Doppler principle. The discovery of the Doppler effect is discussed, the mathematical basis for the Doppler phenomenon as it applies to the one-dimensional wave ...

Arthroscopy Techniques, EarlyView.Abstract Recurrent lateral patellar instability poses a technical challenge to orthopaedic surgeons. Isolated soft‐tissue procedures through medial patellofemoral ligament reconstruction or lateral release show unacceptably high failure rates. Lateral opening wedge distal femoral osteotomy addresses underlying bony malalignment and reinforces the soft ...

Tensions of Sustainability Logics: Performance of a Company Utilizing a Sustainable Business Model
Business Strategy and the Environment, EarlyView.ABSTRACT In recent years, companies have used sustainable business models to gain a competitive advantage. However, there are tensions due to the inconsistency between social, environmental, and economic logic in sustainable business models, making it difficult for companies to change. To understand the existing tensions and interactions between logics,

Maximizing Neurovascular Outcomes of Facial Transplantation: A Comprehensive Review
Clinical Anatomy, EarlyView.ABSTRACT Facial transplantation is a division of reconstructive surgery which aims to improve the function and appearance of a face that has endured severe disfigurement. Currently, the face transplant procedure uses allogenic tissue, harvested from a brain‐dead donor, to replace damaged facial components.
