Comparison by using torsional forces of different fixation techniques in the supracondylar fracture of humerus An anatomic and biomechanical study in the cadaver model

open access: yesActa Orthopaedica et Traumatologica Turcica, 2021
In this study, we performed supracondylar fractures of humerus using adult human cadaver and measured distal fragment resistance to torsional forces by applying five different fixation techniques.

Circular‐Polarization‐Sensitive Organic Photodetectors with a Chiral Nanopatterned Electrode Inverse‐Designed by Genetic Algorithm

open access: yesAdvanced Functional Materials, EarlyView.
A chiral photodetector capable of selectively distinguishing left‐ and right‐handed circularly polarized light is experimentally demonstrated. The device, which features a nanopatterned electrode inverse‐designed by a genetic algorithm within a metal–dielectric–metal nanocavity that incorporates a vacuum‐deposited small‐molecule multilayer, exhibits ...

INFLUENCE OF SOIL STRENGTH PARAMETERS ON THE LATERAL PILE RESPONSE

open access: yesDiyala Journal of Engineering Sciences, 2010
A three-dimensional finite element technique has been used to analyze the single pile lateral under pure lateral load. The main objective of this study is to assess the influence of soil strength parameters (c, ) on the lateral behavior of single pile.

Production-Ready Decomposition of Series Resistance Into Lateral and Fixed Components

open access: yesSiliconPV Conference Proceedings
The series resistance (Rs) of a solar cell is commonly treated as a constant, but this is a very poor approximation: in modern cells, Rs can vary by a factor of 4 depending on illumination, bias voltage, and temperature.

Cross-bidge Kelvin resistor (CBKR) structures for measurement of low contact resistances [PDF]

open access: yes, 2007
A convenient test structure for measurement of the specific contact resistance (ρc) of metal-semiconductor junctions is the CBKR structure. During last few decades the parasitic factors which may strongly affect the measurements accuracy for ρc < 10-6 Ω •

Impact Resistance of Laterized Concrete

open access: yesJournal of Science and Technology (Ghana), 2004
Resistance to impact and other suddenly applied loads Is now recognized as one of the significant properties of normal concrete. Result of test on normal concrete have shown that the introduction of steel or fiber reinforcement into the Lenient matrix has a significant effect on the impact resistance of the concrete.
