Fluid and solute flux between the pleural and peritoneal cavities, although never documented under physiological conditions, might play a relevant role in pathological conditions associated with the development of ascitis and pleural effusion and/or in the processes of tumor dissemination. To verify whether a pleuroperitoneal flux might take place through the diaphragmatic lymphatic network, th...

This work examines the influence of a kerosene flame on residual mechanical tensile properties composite laminates manufactured by thermo-consolidation process from unidirectional (UD) carbon fibers and Polyether Ketone (PEKK) thermoplastic. Considering with two stacking sequences (orthotropic or quasi-isotropic - QI), exposure (116 kW/m2 1100 °C) composites structural integrity was examined as...

Machine learning has been used to accelerate studies in the dynamics of optical pulses. In this study, we use machine investigate optimal design supercontinuum-generating hollow-core antiresonant fibers (HC-ARFs) pressurized and filled with methane. Artificial neural networks (ANNs) are trained replace numerical solvers, simulation fibers, provide a more rapid fiber procedure. We first an analy...

Physical and mechanical performance of natural fiber composites can be tailored by hybridizing with synthetic fibers. Jute fibers are promising highly available at a low cost in some countries, they have been used several applications, the extra benefit helping socially depressed people who commonly explore this plant. This work investigates effect hybridization on properties jute/glass jute/ca...

This work focuses on the assessment of oil palm mesocarp fibers as reinforcement in a composite material with an unsaturated polyester matrix. Several volume ratios OPMF (0 to 15%) were used, being distributed randomly. The resulting was characterized physical and mechanical aspects. Physically, true apparent densities determined well porosity rate. It appears that addition further lightens inc...

Nanoparticles with unique catalytic, electronic, magnetic, optical and optoelectronic properties provide functional building blocks for organization into spatially well-defined assemblies, allowing for the possible extension of desirable properties of these nanoscale entities to the macroscopic level and the realization of complex devices. In the past decade, ‘bricksand-mortar’ assembly strateg...

Ideal implant-cement or implant-bone interfaces are required for implant fixation and the filling of tissue defects created by disease. Micron- to nanosize osseointegrated features, such as surface roughness, fibers, porosity, and particles, have been fused with implants for improving the osseointegration of an implant with the host tissue in orthopedics and dentistry. The effects of fibers and...

Natural-fiber-reinforced composites are seen as a good alternative to traditional synthetic-fiber composites. However, successfully implement these materials in engineering applications, along with demonstrating satisfactory load-bearing capacity, it is necessary provide engineers effective material properties, well calculation methods that take into account the distinctive features of natural ...

The CardioFit vagal stimulation system has been developed as a proposed therapy for congestive heart failure (CHF). CardioFit is to be implanted in several hundred CHF patients enrolled in the INOVATE-HF clinical trial, an FDA approved study. The CardioFit stimulation lead (CSL), which is a cuff electrode that delivers stimulation pulses to the right cervical vagus, was designed to recruit effe...

In this work, artichoke fibers were used for the first time to prepare poly(lactic acid) (PLA)-based biocomposites. In particular, two PLA/artichoke composites with the same fiber loading (10% w/w) were prepared by the film-stacking method: the first one (UNID) reinforced with unidirectional long artichoke fibers, the second one (RANDOM) reinforced by randomly-oriented long artichoke fibers. Bo...
