The concept of cranial Primary Respiratory Mechanism (MRP) is used by osteopathic practitioners to explain the perceptual characteristics arising from the clinical palpation approach of the human skull. The theoretical apparatus and the same MRP existence is always element of controversy among the scientific community. The results arising from this study highlight the intrinsic capability of ...

O presente estudo visou a avaliação, por meio do método dos elementos finitos, das tensões geradas em um arco ortodôntico chamado de Arco de Retração Dupla Chave, também conhecido como DKL. Para isso foram modeladas as geometrias do arco DKL, dos bráquets e das coroas dentais, no software COMSOL Multiphysics®. O modelo criado tem como objetivo a substituição dos métodos tradicionais de ...

Successive studies on graphene, reactive-edge graphene, and pore functionalized graphene were conducted throughout the use of the extended capabilities of COMSOL Multiphysics® modules, modeling and simulating the activation of functionalized building-blocks made of graphene and C- allotrope nanostructures or biostructures (protein). The interdisciplinary approach requested on these studies ...

The NovaSure Endometrial Ablation System® is designed to remove the endometrial lining in the uterine cavity of women who suffer from menorrhagia. The NovaSure disposable device consists of a 2-pole, 4 electrode array that is inserted into the uterine cavity and deployed. We have developed a COMSOL Multiphysics model of the NovaSure ablation process. The model utilized COMSOL Multiphysics ...
Modeling of the Impact of Blood Vessels Flow on the Temperature Distribution During Focused Ultrasound Exposure

Focused ultrasound systems guided by magnetic resonance imaging (MRI) and thermometry have recently made possible the non-invasive thermal ablation of benign tumors such as uterine fibroids in clinical practice. Much more work is however required in order to make this technology available for the treatment of other forms of cancer. One of the major difficulties is associated with the presence of ...
Search for a Suitable Numerical Model for Electrical Stimulation: from the Electric Double Layer to Electrokinetics, Confrontation with Impedance Measurements

Electrical Stimulation is widely used today for Deep Brain Stimulation treatments and retinal prostheses. The Electrical Double Layer formed at the interface between the electrode surface and the extracellular medium is considered thru the linear Helmholtz model and the nonlinear more realistic modified Poisson Boltzmann model. These different models, solved using COMSOL Multiphysics, are ...

MRI offers many advantages over other modalities and its lack of ionizing radiation is important for children, but can be limited by the radio-frequency (RF) coils available. This work calculates Specific Absorption Rate (SAR) and homogeneity of the RF transmit field (B1+) when imaging infants in adult coils. Two birdcage-type coils were loaded by a tissue model and their B1+ homogeneities ...

Implant devices are assistive devices surgically placed in the human body to restore the functionality of organs and tissues. Metallic implants are often used for load bearing applications including the hip and knee joints. To allow maximum flexibility during surgery for surgeons to pick and choose different combinations of parts (say, head, neck and stem, in the case of total hip replacement), ...

The ear doesn’t solely listen but it also speaks. Sounds formed in the inner ear which are measurable in the outer ear are called Otoacoustic emissions (OAEs). Some claim these are produced by the outer hair cells (OHCs), the amplifiers in the inner ear. Our hypothesis is that the OHCs only amplify distortion products (DPs) but do not produce them.

Silk is one of the longest used and most recognizable textiles that we, as a society, use regularly. We see it as a luxury good, worn as an indicator of success and value. However, despite mankind having domesticated and farmed silkworms for millennia, we still know relatively little about the manufacturing process which converts the liquid silk into the fibers we are so familiar with. Increased ...
