Relaxation of surface tension in the free-surface boundary layers of simple Lennard-Jones liquids

In this paper we use molecular dynamics to answer a classical question: how does the surface tension on a liquid/gas interface appear? After defining surface tension from the first principles and performing several consistency checks, we perform a dynamic experiment with a single simple liquid nanodroplet. At time zero, we remove all molecules of the interfacial layer of molecules, creating a fresh bare interface with the bulk arrangement of molecules. After that the system evolves towards equilibrium, and the expected surface tension is re-established. We found that the system relaxation consists of three distinct stages. First, the mechanical balance is quickly re-established. During this process the notion of surface tension is meaningless. In the second stage, the surface tension equilibrates, and the density profile broadens to a value which we call “intrinsic” interfacial width. During the third stage, the density profile continues to broaden due to capillary wave excitations, which does not however affect the surface tension.We have observed this scenario for monatomic Lennard-Jones (LJ) liquid as well as for binary LJ mixtures at different temperatures, monitoring a wide range of physical observables.

Provincialism and the modern diaspora: T.S. Eliot and David Jones

This article considers how T. S. Eliot's promotion of the work of the Anglo-Welsh poet David Jones after the Second World War further involved him in a process of considering the resonances of the local and familiar as operative within the displacements of modernity. This promotion therefore retrospectively prioritized an aspect of Eliot's poetics which had been present, but occluded, all along. Conversely, the article considers how similar resonances in Jones's own work were enhanced by his encounter with Eliot's translation of the Francophone Caribbean poet St-John Perse's Anabase, an encounter which enabled Jones to establish an idiom responsive to the divergent cultural affinities inherent in ‘our situation’.

Relaxation of surface tension in the liquid-solid interfaces of Lennard-Jones liquids

We have established the surface tension relaxation time in the liquid-solid interfaces of Lennard-Jones (LJ) liquids by means of direct measurements in molecular dynamics (MD) simulations. The main result is that the relaxation time is found to be almost independent of the molecular structures and viscosity of the liquids (at seventy-fold change) used in our study and lies in such a range that in slow hydrodynamic motion the interfaces are expected to be at equilibrium. The implications of our results for the modelling of dynamic wetting processes and interpretation of dynamic contact angle data are discussed.

Have You Met Miss Jones? : Identity Construction of a Chick Lit Heroine

Take a random woman in her mid-twenties, with a crazy mother, a lousy job and no sex life, add some insecurity and a lot of alcohol and wrap her up in pink, and congratulations, you have just created your own chick lit heroine.The question is whether a chick lit heroine is this simplistic, or if she carries an important message to the readers. The most important traits in a chick lit novel are the complicated mother-daughter relationship, the career and the love life.Thus, this essay will outline to what extent the postfeminist features are depicted in theidentity of Bridget Jones, as an epitome of later chick lit heroines.

Women of Substance : The Aspect of Education, Career and Female Identity in Pride and Prejudice and Bridget Jones's Diary

Although two hundred years separate Jane Austen and Helen Fielding and, subsequently, also their portrayals of society, the similarities outweigh the differences. When juxtaposing Pride and Prejudice and Bridget Jones’s Diary in the light of feminism it is evident that both books provide clear examples of the prevailing situation of women in each time and place. The aspects of the study, which are especially important today, show both the development and some degree of stagnation of women’s rights and identities.

Jones -v- Bartlett: landlords` liability to tenants and members of their household in negligence

According to the latest available statistics, in 1997-98, of the total of seven million Australian households, two million were renting their dwelling from a State housing authority or private landlords.Therefore, the decision on the scope of landlords' liability to tenants, members of their households, and guests in the right of the tenant handed down by the High Court of Australia in November 2000 was not only of legal, but also of social and economic significance. This note will discuss the Jones v Bartlett case in the context of the traditional common law approach to landlords' liability and the ground-breaking, if flawed, case of Northern Sandblasting Pty Ltd v Harris.
