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 ...

Sleep apnea is a type of sleep disorder characterized by pauses in breathing or instances of shallow or infrequent breathing during sleep. There is a need to diagnose sleep apnea since it leads to fluctuations in the oxygen level that in turn affect the heart rate and blood pressure. In order to detect this disorder, a Micro Electro Mechanical System (MEMS) based piezoelectric pressure sensor ...

Metal reed valves are used for flow rectification in electrohydraulic pumps driven by smart materials at high frequencies but it is difficult to predict their behavior when the surrounding fluid has considerable inertia and viscosity. Simulation of this phenomenon involves modeling the fluid-structure-interaction between the bending of the reed and the flow past the valve. In this model, we use ...

All-solid-state batteries are among the next generation battery concepts that are currently being envisaged among both the international research community and industrial electronic vehicle producers. In addition to a long lifetime of more than several thousand cycles and intrinsic safety, applying solid electrolytes offers a high energy density due to larger electrochemical windows. Aluminum is ...

A obtenção de polpa celulósica antecede a produção de papel e envolve a separação das fibras da madeira mediante a utilização de energia mecânica, térmica, química ou a combinação desses processos. Esta operação é realizada em um reator, tubular, cilíndrico e vertical (tipicamente 6 m de diâmetro e 50 m de altura), denominado genericamente de digestor. A madeira é alimentada pelo topo na forma ...

We have developed a piezoelectrically controlled MEMS drug delivery device for on-demand release of defined quantities of drug. A drug-loaded micro reservoir (∅6mm×550µm) is sealed by A membrane placed over the drug reservoir on which the piezoelectric material is deposited. On application of voltage across this piezoelectric material , the membrane deflects allowing the fluid to fill into the ...

A simulation of an electrodynamic planar loudspeaker (EDPL) has been developed in this study with the COMSOL Multiphysics® software. Using the simulated model, effect of different parts has been studied to improve the performance. The locations of the coil and magnets have been obtained using the magnetic flux density. Then, the sound pressure level and directivity index have been obtained.

Seismic evaluation of existing dams is a major issue that has been even more highlighted by the recent events in Italy. In this regard, researchers and engineers need a reliable and quick tool to assess the complex behaviour of the structure – fluid – soil system. In this paper the soil-structure interaction for concrete gravity dams is considered, investigating its effect on the dynamic ...

Small-scale plasma jets in atmospheric air can produce regions of highly reactive chemistry coincident with temperatures approaching room temperature allowing his type of cold plasma jet to be used for decontamination of surfaces and sterilization of living tissue. In the device under consideration in this work, atmospheric pressure air is forced through a hollow anode and cathode. Immediately ...

The Levitron offers an interesting demonstration of natural magnetic levitation using permanent magnets. It is composed by a small magnetized top and a circular magnetized base with a hole on its center. The top is placed in an area where magnetic field configuration and gyroscopic torques allow the existence of a locus of stable equilibrium. In this paper, we intend to dimension and realize a ...
