Introduction . Keywords, reflecting the main content of article, play an extremely important role in search for scientific papers databases. Together with title and abstract, keywords provide primary information about study. Selecting extracting effective is a time-consuming process, so its optimization requires further studying. Purpose. The article aimed at acquainting authors journal methods...

Acta Academica is an accredited, open access South African journal dedicated to scholarship in the humanities. The publishes independently refereed research articles It promotes perspectives of critical social theory and engagements with postcolonial post-developmental debates special references (Southern) Africa. thereby support scholarly work that examines how humanities twenty-first century ...

A critical issue concerning the deterioration of ageing road infrastructure all around the world is the need to rapidly and cost-effectively evaluate the present condition of pavement infrastructure. Non-Destructive Test (NDT) and evaluation methods are well-suited for characterizing materials and determining structural integrity of pavement systems. The Falling Weight Deflectometer (FWD) is a ...

conclusions there is clinical utility in knowing the relative deflection of various needle tips. when a procedure requires a needle to be steered around obstacles, or along non-collinear targets, the predictable and large amount of deflection obtained through use of a beveled spinal needle may prove beneficial. materials and methods six needles commonly used in spinal procedures (quincke, short...

Unlike well-investigated polymer-based soft actuators such as gel, Ionic Polymer-Metal Composite, conducting polymer, a CFRP-based polymeric laminate possesses quite distinguished properties. It was previously reported that a CFRP-PVC laminate exhibited two-way deflection in accordance with environmental temperature, but it could not exhibit symmetric deflection because of its asymmetric struct...

OBJECTIVES The aim of this study was to assess and compare the characteristics of commonly used initial archwires by their load deflection graphs. MATERIALS AND METHODS This study tested three wire designs namely copper nickel titanium (CNT), nickel titanium (NiTi), and multi-strand NiTi (MSNT) archwires engaged in passive self-ligating (PSL) brackets, active self-ligating (ASL) brackets or c...

An optically thin resonator suspended over a substrate and illuminated with a laser forms an interference field that couples deflection of the resonator to absorption within it. For high enough laser powers, such resonators have been shown to be interferometrically transduced to stable oscillations due to the feedback between heating and deflection. The coupling between thermal stresses, deflec...

Robot-assisted surgery is of growing interest in the surgical and engineering communities. The use of robots allows surgery to be performed with precision using smaller instruments and incisions, resulting in shorter healing times. However, using current technology, an operator cannot directly feel the operation because the surgeon-instrument and instrument-tissue interaction force feedbacks ar...

At electrophysiologic study in a patient with the Wolff-Parkinson-White syndrome, intracardiac catheter recordings demonstrated a deflection that occurred 30 ms before ventricular activation. The rapid deflection was present during ventricular preexcitation but not during normal atrioventricular conduction. All QRS complexes were preexcited to varying degrees during atrial fibrillation, yet the...
