the fringes areas interposed between metropolis and territorial ecosystems constitute a new sort of geography of urban sprawl. the difference between urban areas and their surroundings is at present unrecognisable.from this new context, that represent a new life environment for a large part of human population, new perceptive dynamics and new relationships emerge. various social manifestations ...

We have previously developed an adsorption-limited model to describe the exchange of lung surfactant and its fractions to and from an air-liquid interface in oscillatory surfactometers. Here we extend this model to allow for diffusion in the liquid phase. Use of the model in conjunction with experimental data in the literature shows that diffusion-limited transport i.s important for characteriz...

We consider a model mixing sharp and diffuse interface approach for the seawater intrusion phenomenon in confined aquifers. The aim of this work is to introduce analyze new mixed formulation, obtained by writing problem into matrix form, introducing variable σ = R ( u )∇ representing flux tensor primal h , Φ f ) T . Here, represents depth salt/freshwater interface, hydraulic head freshwater, R(u...

Perpendicular magnetic anisotropy (PMA) has recently been shown to emerge at interfaces of 3d and 5d transition-metal oxides (TMOs). However, strategies systematically stabilize such interface-driven PMA still remains elusive, hindering further applications this design approach. Here, tuning crystal symmetry is be an effective means engineer interfacial phenomenon. The evolution strength as a f...

A finite-difference hybrid numerical method for the solution of isothermal fluctuating hydrodynamic equations is proposed. The primary focus to ensure positivity-preserving property scheme, which critical its functionality and reliability especially when simulating vapour systems. Both cases single- two-phase flows are considered by exploiting van der Waals' square-gradient approximation model ...

Experimental investigation was conducted to explore the formation conditions and provide new insights into mechanisms of unexplained intermixing phenomenon observed at substrate-coatings interface cold sprayed materials. The results indicate that significantly depends on extent plastic deformation coating-substrate interface, with severe creating favorable for interface. Two factors have been i...

At their worst, fires at the rural–urban or wildland–urban interface cause tragic loss of human lives and homes, but mitigating these fire effects through management elicits many social and scientific challenges. This paper addresses four interconnected management challenges posed by socially disastrous landscape fires. The issues concern various assets (particularly houses, human life and biod...

A gas-liquid interface involves complex physics along with unknown phenomena related to thermodynamics, electromagnetics, hydrodynamics, and heat and mass transfer. Each phenomenon has various characteristic time and space scales, which makes detailed understanding of the interfacial phenomena very complex. Therefore, modeling the gasliquid interface is a key issue for numerical research on mul...
