Abstract Industrial washing is essential in manufacturing and many other technological fields. Nowadays, steam the most common technique. However, it involves chemical solvents which are potentially noxious for environment difficult to be disposed of. Therefore, there a growing demand alternative techniques that would ensure low operating costs, extensive productivity, high efficiency, environm...

With the development of world economies and continuous improvement living standards, pharmaceutical personal care products (PPCPs) have attracted significant attention because their widespread detection in wastewater natural environment. Their biological toxicity, environmental persistence, other hazardous characteristics might pose a threat to ecological environment human health. How treat sou...

Magnetic artificial cilia (MAC) are small actuators inspired by biological found in nature. In microfluidic chips, MAC can generate flow and remove microparticles, with applications anti-fouling. However, the used for anti-fouling current literature has dimensions of several hundred micrometers length, which limits application to relatively large length scales. Here, biologically-sized magnetic...

While technical debt grows in absolute numbers as software systems evolve over time, the density of (technical divided by lines code) is reduced some cases. This can be explained either application refactorings or development new artifacts with limited Technical Debt. In this paper we explore second explanation, investigating relation between amount Debt code and evolution system. To end, compa...

The removal of necrotic and vital pulp substrates microorganisms their toxins from the root canal system (RCS) has been found to be basis for a successful endodontic treatment. In this study, our aim was evaluate effect passive ultrasonic irrigation (PUI) on elimination organic remnant tissue infected, narrow curved mandibular canals during instrumentation. For purpose, mesiobuccal first molars...

Abstract Precise radial velocity (PRV) surveys are important for the search Earth analogs around nearby bright stars, which induce a small stellar reflex motion with an RV amplitude of ∼10 cm s −1 . Detecting such signal poses challenges to instrumentation, data analysis, and precision astrophysical models mitigate jitter. In this work, we investigate component in PRV error budget—the spectral ...

Walkability has become a research topic of great concern for preserving public health, especially in the era COVID-19 outbreak. Today more than ever, urban and transport policies, constrained by social distancing measures travel restrictions, must be conceptualized implemented with particular emphasis on sustainable walkability. Most walkability models apply observation subjective methods to me...

Natural gas hydrate (NGH) is widely considered as an alternative energy source due to its tremendous reserves, cleanness and high density. During the exploitation process, discharging gas-liquid phase surface for separation not only affects pump performance but also increases space requirements of offshore platform. Taking NGH production test data in South China Sea example, a downhole spiral s...
