Context. Runaway stars with peculiar high velocities can generate stellar bow shocks. Only a few bow shocks show clear radio emission. Aims. Our goal is to identify and characterize new stellar bow shocks around O and Be...

Owing to weak light-matter interactions in natural materials, it is difficult to dynamically tune and switch emission polarization states of plasmonic emitters (or antennas) at nanometer scales. Here, by using a control ...

Issues that arise in the practical implementation of the Phillips et al. (2011) and Phillips et al. (2015a) recursive procedures for identifying and dating explosive episodes in time series are considered. It is argued t...

Abstract This research aims at studying the stable flow of the viscous thin membranes in a two-dimensional system in a declined way, neglecting the inertia powers. The equation that controls the flow was found by means o...

Nonlinear optical processes are vital for fields including telecommunications, signal processing, data storage, spectroscopy, sensing and imaging. As an independent research area, nonlinear optics began with the inventio...

Abstract Cavitation generation methods have been used in multifarious directions because of their diversity, and numerous studies and discussions have been conducted on cavitation generation methods. This study aims to e...

The COVID-19 pandemic has hit the transportation sector hard; particularly air transportation, as a major mode of long-distance transportation, has been affected tremendously. Since the dawn of COVID-19, politicians and ...

Estudou-se a ontogênese da Teoria da Mente (atribuição de pensamentos e conteúdos mentais a outros indivíduos) por meio da representação gráfica de “balões de pensamento”, examinando-se indicadores de difere...

The interaction between a stellar wind and its surrounding ISM can create H I cavities or bubbles. In particular, WR 6 shows a very large ovoidal H I bubble around it, whose shape cannot be explained in terms of the stan...

The gassy soil containing entrapped gas bubbles is a special type of unsaturated soils, and the compressibility of air-water mixture in gassy soils cannot be ignored. Based on the conceptual model for small bubbles, the ...

Abstract The spherical valve plate/cylinder block pair has the advantages of strong overturning resistance and large bearing area. However, the configurations of the unloading and pre-boosting triangular grooves on the s...

We directly characterize nanoscale spatiotemporal inhomogeneities of multi-layered molybdenum diselenide (MoSe2) in real space and time – the nanometre–femtosecond scale, attributing to local mechanical structures su...

This paper is about the development of a system that purifies contaminated water with micro-bubbles for solutions of water pollutions such as industrial waste water, rivers, lakes, dams, ground water and ocean. The syste...

Chemosynthetic ecosystems host unique geological, biogeochemical, microbial and faunistic settings, which provide key ecosystem services for human wellbeing. In the Argentine continental margin, the existence of chemosyn...

Abstract The water-lubricated bearings are usually the state of turbulent cavitating flow under high-speed conditions. And the distribution of cavitation bubbles and the interface effect between the two phases have not b...

The porous electrodes used in the EC treatment of emulsified oil wastewater were designed, and a study of the synergistic electro-flotation mechanism in this process was conducted using COMSOL Multiphysics simulation sof...

ABSTRACT To analyze the effects of variables on venous blood specimens from dogs intended for blood gas analysis, four samples were collected from the jugular veins of 30 animals. Two were obtained using a commercial 3mL...

Abstract In order to resist on the cavitation erosion, many researchers try to change the solidity and tenacity of the coatings, but ignore the influence of surface characteristics of materials on cavitation flow and the...

The electrolytic desaturation method, as an innovative mitigation of soil liquefaction, is proposed in recent years. Liquefaction resistance can be improved by the air bubbles produced by electrolysis of the pore water i...

Abstract Cavitation inside a torque converter induces noise, vibration and even failure, and these effects have been disregarded in previous torque converter design processes. However, modern torque converter application...

Multiphase flows are very common in industrial operations. In offshore oil and gas production, transient processes in long pipelines can lead to water accumulation, which must be removed using gas–oil mixtures. The slu...

Fused deposition modeling is an additive manufacturing technique that enables complex structures to be fabricated layer by layer using thermoplastic filaments. The most common usage is based on the fact that polylactic a...

Are surface nanobubbles transient or thermodynamically stable structures? This question remained controversial until recently, when the stability of gas nanobubbles at solid−liquid interfaces was demonstrated from ther...

Understanding shielding cross-effects is a prerequisite for maximal power-specific nanosecond laser ablation in liquids (LAL). However, discrimination between cavitation bubble (CB), nanoparticle (NP), and shielding, e.g...
