Las columnas de Juan José Millás.

Se describe los artículos periodísticos de opinión que realiza Juan José Millás en el periódico El País. Se expone una de sus columnas llamada Oraciones, y junto a ella un comentario explicativo de la misma. Esta columna está basada en la construcción de una frase, con la que se demuestra la necesidad de la competencia lingüística y del estructuralismo lingüístico. Se compara la construcción de una frase con el recorrido de un jugador de fútbol hasta la portería contraria y también se compara con los huesos de las articulaciones los cuáles no pueden vivir unos sin otros. Se refleja en gran medida el componente irónico que utiliza Millás en sus artículos con el fin de divulgar sus conocimientos y pensamientos.

Satanic Mills? An illustration of Victorian external environmental accounting

The paper evaluates a Victorian environmental account of the pollution of the River Wandle. This account was produced during a period of social and environmental crisis, when there were no significant industrial environmental regulations. This problematising external environmental account provides valuable insights into the historical development of social and environmental accounting. Our analysis located this account within an institutional reform programme to create systems of governance to mitigate the damage arising from unfettered industrial growth. We argue that problematising external environmental accounting has a longer tradition than previously recognised in the literature and predates corporate social and environmental reporting.

Use of Primary Sludge from Pulp and Paper Mills for Nanocomposites

Cellulose nanocrystals have been evaluated as reinforcement material in polymeric matrices due to their potential to improve the mechanical, optical, and dielectric properties of these matrixes. This work describes how high pressure defibrillation and chemical purification affect the sludge fiber morphology from micro to nanoscale. Microscopy techniques and X-ray diffraction were used to study the structure and properties of the prepared nanofibers and composites. Microscopic studies showed that the used individualization processes lead to a unique morphology of interconnected web-like structure of sludge fibers. The nanofibers are bundles of cellulose fibers having widths (5 to 30 nm) and estimated lengths of several micrometers.

Infrared degrees of freedom of Yang-Mills theory in the Schrodinger representation

We set up a new calculational framework for the Yang-Mills vacuum transition amplitude in the Schrodinger representation. After integrating out hard-mode contributions perturbatively and performing a gauge-invariant gradient expansion of the ensuing soft-mode action, a manageable saddle-point expansion for the vacuum overlap can be formulated. In combination with the squeezed approximation to the vacuum wave functional this allows for an essentially analytical treatment of physical amplitudes. Moreover, it leads to the identification of dominant and gauge-invariant classes of gauge field orbits which play the role of gluonic infrared (IR) degrees of freedom. The latter emerge as a diverse set of saddle-point solutions and are represented by unitary matrix fields. We discuss their scale stability, the associated virial theorem and other general properties including topological quantum numbers and action bounds. We then find important saddle-point solutions (most of them solitons) explicitly and examine their physical impact. While some are related to tunneling solutions of the classical Yang-Mills equation, i.e. to instantons and merons, others appear to play unprecedented roles. A remarkable new class of IR degrees of freedom consists of Faddeev-Niemi type link and knot solutions, potentially related to glueballs.
