A Comparative Study on Drill Tool Effect on Vibration and Delamination Characteristics of FRPs

Journal of Natural Fibers, 2022
Drilling is an inevitable process for component assembly which need appropriate control aiming damage reduction. To study such drill-induced damages, Glass and Natural fiber composites with unidirectional (11) and cross-ply lay-up (12) were drilled using

Voice and Speech in Atypical Parkinsonian Disorders

Movement Disorders Clinical Practice, EarlyView.
Background Motor speech disorders are early, common, and functionally limiting features of atypical parkinsonian disorders (APDs) such as progressive supranuclear palsy (PSP), corticobasal syndrome (CBS), and multiple system atrophy (MSA). These impairments are underrecognized and undertreated in neurology clinics.

Modeling n‐Butyl Acrylate Polymerization using Complementary Modeling Techniques

Macromolecular Reaction Engineering, EarlyView.
Two different simulation methods are used for the radical polymerization of nBA: deterministic in Predici and stochastic with mcPolymer. It has been successfully implemented across a wide temperature range. It turns out that the partially different implementation of chain‐length‐dependent termination and β‐scission are important for obtaining ...

Effect of Externally Bonded Strips of Polymer Fiber (frp) on the Shear Strength of R.C Beam [PDF]

Kirkuk Journal of Science, 2010
This research includes the findings of a workable study investigation for topic of externally strengthening by polymer fiber strips (FRP) of shear span and its impact on the behavior of reinforced concrete beams. The study was carried out by casting (18)

Nonlinear Vibration Characteristic Analysis of Electric Vehicle–Road Coupling System

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In‐wheel motor drive is the developing direction of automobile electrification and intelligence. However, the increased unsprung mass in in‐wheel motor‐driven electric vehicles (IWMEVs) leads to higher dynamic tire loads, thereby intensifying vehicle–road coupling interactions. To address this problem, an 11‐degree‐of‐freedom nonlinear dynamic

Reinstatement and generic reassignment of Phyllanthus asteranthos Croizat (Phyllanthaceae) based on living plant observations and specimen analysis

Nordic Journal of Botany, EarlyView.
Phyllanthus asteranthos Croizat has been treated as a synonym of P. pulcher Wall. ex Müll. Arg. (syn. Nymphanthus glaucescens (Miq.) R.W.Bouman) since 1987. Through detailed morphological observations of living plants and critical examinations of type materials and additional specimens, this study revealed that the two taxa are morphologically very ...

Examination of influential factors on shear strength of externally bonded FRP reinforcement in RC beams

Journal of Materials and Engineering Structures, 2020
The fiber-reinforced polymer (FRP) retrofitting technique has been increasingly created to enhance the capacity of the existing concrete members. In this study, the shear contribution of the external FRP strengthening system in the reinforced concrete ...

Damage-Based Seismic Retrofitting Approach for Nonductile Reinforced Concrete Structures Using FRP Composite Wraps

Advances in Civil Engineering, 2020
Applying similar amount of fibre reinforced polymer (FRP) for all plastic hinge locations in a structure is not an ideal approach as damage occurring at these critical locations may vary considerably.

Global analysis of annual survival among shorebirds reveals a negative effect of migration distance and a decline in recent decades

Oikos, EarlyView.
Annual survival is a key demographic parameter driving population trends in wildlife populations. However, despite numerous species‐specific or regional studies, global reviews of the factors affecting the survival of declining taxa remain scarce. Here, we investigated annual survival of fledged immature and adult shorebirds, a globally‐distributed and
