Nickel-cerium (Ni-Ce) alloys of different compositions were fabricated and evaluated as electrodes for hydrogen evolution reaction (HER) in alkaline media. HER at Ni-Ce electrodes was studied in 8 M KOH solution for temperatures ranging from 25 to 85°C. Polarization curves were recorded using both Ni-Ce alloys and pure Ni electrode, and further analyzed enabling determination of main kinetic parameters. The parameters determined, namely Tafel coefficients, charge transfer coefficients, exchange current ...

The aim of this study was to analyse the prevalence of barriers to physical activity (PA) among adults according to the gender and socioeconomic status (SES). A total of 2236 subjects (927 men, 1309 women) aged between 30 and 50 y (M = 42±5 y) participated in the study. The data was collected through a questionnaire. Qui-square tests were performed to analyse the differences between genders and SES on perceived barriers. Significance level was p <0.05. Only 31% (32% male, 31% female) achieved the current ...

In this work, we present a derivation for the lattice-Boltzmann equation directly from the linearized Boltzmann equation, combining the following main features: multiple relaxation times and thermodynamic consistency in the description of non isothermal compressible flows. The method presented here is based on the discretization of increasingly order kinetic models of the Boltzmann equation. Following a Gross-Jackson procedure, the linearized collision term is developed in Hermite polynomial tensors ...

In the field of rehabilitation of separate sanitary sewer systems, a large number of technical, environmental, and economic aspects are often relevant in the decision-making process, which may be modelled as a multi-objective optimization problem. Examples are those related with the operation and assessment of networks, optimization of structural, hydraulic, sanitary, and environmental performance, rehabilitation programmes, and execution works. In particular, the cost of investment, operation and ...

ABSTRACT Reconstituted wood panels are widely used in various branches of the wood industry, such as in the furniture sectors and various segments of urban and rural construction. In Brazil, agricultural and forestry residues are abundantly generated, making feasible the study, development and application of alternative and sustainable materials, produced from the use of these wastes. The aim of this study was to produce high-density homogenous panels with wood residues of Pinus elliottii and oat ...

In the last few decades, many studies have revealed the potential role of arthropod bacterial endosymbionts in shaping the host range of generalist herbivores and their performance on different host plants, which, in turn, might affect endosymbiont distribution in herbivore populations. We tested this by measuring the prevalence of endosymbionts in natural populations of the generalist spider mite Tetranychus urticae on different host plants. Focusing on Wolbachia, we then analysed how symbionts ...

Abstract In fluid mechanics, multicomponent fluid systems are generally treated either as homogeneous solutions or as completely immiscible parts of a multiphasic system. In immiscible systems, the main task in numerical simulations is to find the location of the interface evolving over time, driven by normal and tangential surface forces. The lattice-Boltzmann method (LBM), on the other hand, is based on a mesoscopic description of the multicomponent fluid systems, and appears to be a promising ...

Nickel–dysprosium (Ni–Dy) and nickel–samarium (Ni–Sm) alloys with 5 and 10 at% of rare earth metal were prepared by arc melting and by induction furnace melting, respectively. The alloys microstructure, morphology and chemical composition were inspected by scanning electron microscopy and energy dispersive X-ray analysis; phases crystal structure and lattice parameters were confirmed by X-ray diffraction analysis. The alloys were used for fabrication of electrodes for hydrogen evolution reaction (HER) ...

Abstract Low‐cost molybdenum carbide (Mo 2 C) nanoparticles supported on carbon nanotubes (CNTs) and on carbon xerogel (CXG) were prepared and their activity for the hydrogen evolution reaction (HER) was evaluated in 8 m KOH aqueous electrolyte at 25–85 °C. Measurements of the HER by linear scan voltammetry allowed us to determine Tafel slopes of 71 and 74 mV dec −1 at 25 °C for Mo 2 C/CNT and Mo 2 C/CXG, respectively. Stability tests were also performed, which showed the steady performance of the two ...

Periodontal disease (PD) is one of the most frequent and widespread inflammatory diseases in dogs. The onset of PD pathogenesis is prompted by the dental microbial biofilm combined with the animal immune-inflammatory response. Along with local effects, systemic consequences can occur secondary to dental plaque-associated bacteraemia, affecting distant tissues and organs. The main goal of this retrospective study was to access and evaluate the association between PD and systemic consequences (renal, ...
