Treatment of neglected elbow dislocations with the help of hinged external fixator: Report of two cases [PDF]

open access: yes, 2014
Elbow dislocations are cases that have to be treated in emergency conditions. Neglected elbow dislocations are seen very rarely and the treatment of such cases are more complicated than acute cases.

Melt Grafting of Geometry‐Tailored Voltage Stabilizers for High‐Performance Polypropylene Insulation

open access: yesAdvanced Functional Materials, EarlyView.
A scalable one‐step melt grafting strategy is developed to enhance the dielectric properties of isotactic polypropylene by covalently incorporating thermally stable aromatic voltage stabilizers. This solvent‐free approach improves volume resistivity and DC breakdown strength through deep trap formation and charge localization, offering a sustainable ...

Retrospective analysis of surgical treatments of sternoclavicular joint dislocation: literature review

open access: yesГений oртопедии, 2018
Traumatic injuries to the sternoclavicular joint (SCJ) dislocations account for less than 3% of all joint dislocations. However, instrumentation fixation is frequently associated with high-risk complications that lead to disability. The authors sought to

Towards the grain boundary phonon scattering problem: an evidence for a low-temperature crossover

open access: yes, 1998
The problem of phonon scattering by grain boundaries is studied within the wedge disclination dipole (WDD) model. It is shown that a specific q-dependence of the phonon mean free path for biaxial WDD results in a low-temperature crossover of the thermal ...

Microstructural and Corrosion Properties of Cold Rolled Laser Welded UNS S32750 Duplex Stainless Steel [PDF]

open access: yes, 2018
The main goal of this work was to study the effect of plastic deformation on weldability of duplex stainless steel (DSS). It is well known that plastic deformation prior to thermal cycles can enhance secondary phase precipitation in DSS which can lead to

Atomic‐Level Dual‐Cation Engineering Enables High‐Performance Na4VMn(PO4)3 Cathodes for Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Dual‐cation site engineering unlocks stable and fast sodium storage in Na4VMn(PO4)3 cathodes. Li+ at Na2 suppresses Jahn‐Teller distortion, while K+ at Na1 expands ion channels, enabling synchronized V/Mn redox and quasi‐single‐phase kinetics. This atomic‐level strategy achieves ultralong cycling stability, high‐rate capability, and full cell viability

Surgical treatment options for AC joint dislocation: Comparison of clinical outcomes of TightRope and hook plate methods

open access: yesMedicine Science
Acromioclavicular (AC) joint dislocations frequently occur in young and active individuals, resulting in pain, restricted movement, and functional limitations. Among surgical treatments, TightRope and hook plate methods are commonly used.

Eenvoudige elleboogluxaties in Nederland: Wat doen Nederlandse chirurgen? [PDF]

open access: yes, 2009
: Er is weinig evidence voor de optimale behandeling van eenvoudige elleboogluxaties. Hoewel er aanwijzingen zijn dat eenvoudige elleboogluxaties niet te lang moeten worden geïmmobiliseerd en functioneel kunnen worden nabehandeld.
