Copenhagen consensus statement 2019: physical activity and ageing

2019

From 19th to 22nd November 2018, 26 researchers representing nine countries and a variety of academic disciplines met in Snekkersten, Denmark, to reach evidence-based consensus about physical activity and older adults. It was recognised that the term ‘older adults’ represents a highly heterogeneous population. It encompasses those that remain highly active and healthy throughout the life-course with a high intrinsic capacity to the very old and frail with low intrinsic capacity. The consensus is drawn from a wide range of research methodologies within epidemiology, medicine, physiology, neuroscience, psychology and sociology, recognising the strength and limitations of each of the methods. …

DIRECT NUMERICAL SIMULATION OF MOTION OF FERROMAGNETIC PARTICLES IN MAGNETORHEOLOGICAL SUSPENSION

2008

ABSTRACT Results simulation of magnetorheological suspension at particle level are reported. The present approach accounts for a better description of hydrodynamic interaction between close spheres. Development of lamellar structures similar to those obtained by other researchers in Poiseuille flow is observed in shear flow. Studies of single layer lamellar structures reveal presence of short chains and more complex aggregates.

Comparison of Dissipative Particle Dynamics and Langevin thermostats for out-of-equilibrium simulations of polymeric systems

2007

In this work we compare and characterize the behavior of Langevin and Dissipative Particle Dynamics (DPD) thermostats in a broad range of non-equilibrium simulations of polymeric systems. Polymer brushes in relative sliding motion, polymeric liquids in Poiseuille and Couette flows, and brush-melt interfaces are used as model systems to analyze the efficiency and limitations of different Langevin and DPD thermostat implementations. Widely used coarse-grained bead-spring models under good and poor solvent conditions are employed to assess the effects of the thermostats. We considered equilibrium, transient, and steady state examples for testing the ability of the thermostats to maintain const…

Między spotkaniem a mijaniem. Rahel Varnhagen, Hannah Arendt, Judith Butler

2020

The article is an attempt at capturing the relationship between the lives and creative attitudes of Rahel Varnhagen, Hannah Arendt and Judith Butler. Starting with Varnhagen’s biography written by Arendt, the essay’s author wonders about the philosopher’s writing strategy. Instead of a classic reconstruction of life, the biographer offers a collage of excerpts from Rahel’s letters with extensive commentary. This form encourages one to read Rahel Varnhagen as a narration about the author and her own struggle with Jewish and female identity. The second relationship analysed in the essay is the impact of Hannah Arendt’s texts on Judith Butler’s writings. Despite the criticism of the philosophe…

Contexto editorial, cultural y socio-político de la edición príncipe de la «Historia de la doncella Teodor» (Toledo: Pedro Hagenbach, 1500-1501)

2021

The material analysis of the only surviving copy of the editio princeps of the Historia de la doncella Teodor allows us to date it back to the incunabula era and to attribute its printing to Pedro Hagenbach’s workshop. The close relationship amongst Hagenbach’s workshop, the reformist project of Archbishop Cisneros, and the interests of the Catholic Monarchs sets an editorial and cultural context that supports the adaptation of Teodor to the printing press. This work perfectly agreed with the thematic and ideological guidelines for the renewal of Christian customs and values. The forceful religious and intellectual imposition of the young and learned slave, turned into a “fijadalgo” in the …

Challenges in EU External Climate Change Policy-Making in the Early Post-Lisbon Era: The UNFCCC Copenhagen Negotiations

2011

The 15th United Nations Framework Convention on Climate Change (UNFCCC) Conference of the Parties (COP) meeting held in Copenhagen from 7 to 18 December 2009, which took place one week after the entry into force of the Treaty of Lisbon on 1 December 2009, has brought about rather disappointing outcomes from the perspective of the European Union (EU), which had previously displayed substantial leadership within the UN climate regime. Contrary to the EU’s objectives for the COP15 meeting, no legally binding agreement was reached to succeed the Kyoto Protocol after 2012 and the final Copenhagen Accord contained disappointingly few ambitious targets. This chapter tries to explain how this resul…

Statistical Modeling for the Flow of Short Fibers Composites

1994

Numerical results are given for the flow of fiber composites modelled as suspensions of non spherical particles. In this framework, because the many particles rotate, their state of orientation is described with a statistical approach. We used these methods to compute coupled solutions in which the orientation of the particles is affected by the flow and the flow itself depends on the orientation of the particles. The computation methods involve an augmented lagrangian approach and a streamline upwind petrov galerkin formulation to solve the convective orientation equation.

Self-assembly of colloidal micelles in microfluidic channels.

2016

The self-assembly of amphiphilic Janus colloids in microfluidic channels is studied using hybrid molecular dynamics simulations with fully resolved hydrodynamic interactions incorporated through the multi-particle collision dynamics algorithm. The simulations are conducted at a density and temperature where the Janus particles spontaneously self-assemble into spherical micelles to minimize the interface between the solvophobic caps and the surrounding solvent. In confined systems, this contact area can also be reduced by aggregation at the channel walls. Indeed, a sizable fraction of free particles and small clusters with three and four members are found at the walls when the microfluidic c…
