Bilateral Asymmetrical Hip Dislocation in a 70-year-old Female: A Rare Case Report

Journal of Orthopedics, Traumatology and Rehabilitation
Traumatic dislocation of the hip joint is a rare injury representing 2%–5% of all dislocations while bilateral hip dislocation accounts for 1.25% of all hip dislocations.

Impact of Various Rotary Friction Welding Process Parameters on the Mechanical Properties of a Steel–Aluminum Joint

Advanced Engineering Materials, EarlyView.
Rotary friction welding of steel E355 and the aluminum alloy EN AW‐6082 can lead to the formation of brittle intermetallic phases. The primary process parameters are varied in order to determine their influence on this intermetallic phase formation and the resulting mechanical properties.

Two Approaches to Dislocation Nucleation in the Supported Heteroepitaxial Equilibrium Islanding Phenomenon

, 2008
We study the dislocation formation in 2D nanoscopic islands with two methods, the Molecular Static method and the Phase Field Crystal method. It is found that both methods indicate the same qualitative stages of the nucleation process.

Mobility of Dislocations in Aluminum [PDF]

, 1969
The velocities of individual dislocations of edge and mixed types in pure aluminum single crystals were determined as a function of applied‐resolved shear stress and temperature.

Ultrahigh Piezoelectricity in Truss‐Based Ferroelectric Ceramics Metamaterials

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
By leveraging the unique combination of polarization direction and loading state, ultrahigh piezoelectricity is achieved through careful tuning of the relative density and scaling ratio in truss‐based ferroelectric metamaterials. This approach enables the simultaneous realization of extremely high piezoelectric constants and ultralow dielectric ...

Surgical versus non-surgical interventions for treating patellar dislocation [PDF]

, 2015
Background: Patellar dislocation occurs when the patella disengages completely from the trochlear (femoral) groove. Following reduction of the dislocation, conservative (non-surgical) rehabilitation with physiotherapy may be used.

Gate‐Tunable Hole Transport in In‐Plane Ge Nanowires by V‐Groove Confined Selective Epitaxy

Advanced Functional Materials, EarlyView.
Ge nanowires are promising for hole spin‐based quantum processors, requiring direct integration onto Si wafers. This work introduces V‐groove‐confined selective epitaxy for in‐plane nanowire growth on Si. Structural and low‐temperature transport measurements confirm their high crystalline quality, gate‐tunable hole densities, and mobility.

Topological indices, defects and Majorana fermion in chiral superconductors

, 2012
We study theoretically the role of topological invariants to protect the Majorana fermions in a model of two-dimensional chiral superconductors which belong to class D of topological periodic table. A rich phase diagram is revealed.

Temporomandibular joint dislocation in Nairobi

East African Medical Journal, 2010
Despite the diverse conservative and surgical modalities for the management of temporomandibular joint (TMJ) dislocation and the controversy that surrounds them, very little has been done within the East-African setup in terms of highlighting and provoking greater interest in the epidemiology and management of TMJ dislocation.To audit the pattern of ...

Intraoral Drug Delivery: Bridging the Gap Between Academic Research and Industrial Innovations

Advanced Functional Materials, EarlyView.
Intraoral drug delivery offers a promising route for systemic and localized therapies, yet challenges such as enzymatic degradation, limited permeability, and microbial interactions hinder efficacy. This figure highlights innovative strategies—mucoadhesive materials, enzyme inhibitors, and permeation enhancers—to overcome these barriers.
