Isogeometric Resolution of the Brinkman-Forchheimer-Darcy [PDF]

open access: yesJournal of Applied and Computational Mechanics
In this paper, we employ the finite element method based on non-uniform rational B-splines function approximation to solve the nonlinear Brinkman-Forcheimer-Darcy equation in a simply connected and bounded Lipschitz domain Ω.

The Influence of Preload on the Work of Angular Contact Ball Bearings

open access: yesArchive of Mechanical Engineering, 2016
Optimum values of preload can be achieved in well-tried constructions and then applied in similar structures. For new structures, it is recommended to calculate the preload force and to test the correctness of calculation by means of experiments.

Correction: Vascular regression precedes motor neuron loss in the FUS (1-359) ALS mouse model

open access: yesDisease Models & Mechanisms, 2019
Amyotrophic lateral sclerosis (ALS) presents a poorly understood pathogenesis. Evidence from patients and mutant SOD1 mouse models suggests vascular damage may precede or aggravate motor dysfunction in ALS.

Stem cell therapy and FUS[1‐359]‐transgenic mice: A recent study highlighting a promising ALS model and a promising therapy

open access: yesCNS Neuroscience & Therapeutics, 2020
Amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, is a motor neuron disease (MND), that were first described in 1869 by French neurologist Jean-Martin Charcot.1 This fatal neurodegenerative disorder affects motor neurons and other neuronal ...

Microplastic sources, formation, toxicity and remediation: a review

open access: yesEnvironmental Chemistry Letters, 2023
Microplastic pollution is becoming a major issue for human health due to the recent discovery of microplastics in most ecosystems. Here, we review the sources, formation, occurrence, toxicity and remediation methods of microplastics. We distinguish ocean-

Primary Shoulder Hemiarthroplasty: What Can Be Learned From 359 Cases That Were Surgically Revised?

open access: yesClinical Orthopaedics and Related Research, 2018
Background Primary shoulder hemiarthroplasty is used to address a range of glenohumeral disorders, including fracture, arthritis, avascular necrosis, and capsulorrhaphy arthropathy; some patients with hemiarthroplasties undergo revision surgery for ...

Stabilization of a nonlinear Euler-Bernoulli viscoelastic beam subjected to a neutral delay [PDF]

open access: yesTheoretical and Applied Mechanics
An approach is implemented in this article to analyze the decay rate of nonlinear beams according to the Euler–Bernoulli equation in the context of rheological viscoelastic damping deformations taking into account the neutral type delay.
