No full textUsing plant-level data on Chilean manufacturing firms for the 1980-2001 period, we estimate and characterize disaggregate total factor productivity. We use these estimates to study the microeconomic sources of aggregate efficiency, a fundamental part of aPlant dynamics, total factor productivity, growth, chilean manufacturing
Mathematical Models of Vitreous Humour Dynamics and Retinal Detachment
No full textThe vitreous humour is a gel-like substance, which fills the vitreous chamber at the posterior part of the eye. It is a clear transparent material that can be mechanically characterised as a visco-elastic fluid. The vitreous has the important role of holding the retina in contact with the retinal pigment epithelium. During vitreous motion vitreoretinal tractions are generated and this might potentially lead to retinal detachment (RD). Studying the vitreous mechanical behaviour is thus relevant for understanding the physiology and pathophysiology of the eye. Mathematical modelling has provided significant contributions into understanding vitreous dynamics and the role it has on the occurence of vitreoretinal pathologies. In this chapter we first discuss works addressing vitreous motion induced by eye rotations and the possible generation of large mechanical stresses on the retina. Secondly we discuss models associated with RD, focusing on the progression of rhegmatogenous RD and the formation of exudative RD
"Non di sola CEDU ..." La fecondazione assistita e il diritto alla salute in Italia e in Europa
No full textIn recent years, the right to health granted by Art. 32 of the Italian Constitution has undergone a significant shift. Along with the increasing process of Europeanization of fundamental rights, which was boosted in 2007 in relation to the ECHR, both the individual and the social tenets of the right to health seem to have been progressively blurring. A powerful example of this trend is that concerning assisted reproductive technology (ART). A law passed in 2004 has regulated ART in Italy for the first time ever, albeit with a highly restrictive approach. Many claims over time have challenged the constitutionality of the law and, among them, those affecting the bans on preimplantation genetic diagnosis and on heterologous assisted reproduction remain unanswered to date. The inaction of the Constitutional Court and the unresponsiveness of the legislative branch have therefore pushed the affected couples to apply to the European Court of Human Rights, whose decisions have partially satisfied those claims, albeit with the effect of jeopardizing the centrality of the constitutional right to health and its multi-faceted potentialities. The right to respect for private and family life (Art. 8 ECHR) is indeed focused on the individual side of health issues and mainly lacks any social attitude, with the consequence that 'reproductive' rights (i.e. the right to have a child) are often overestimated with regard to woman's health rights. The inability of this approach to call into question the most critical aspects of the Italian legislation on ART has been demonstrated by the latest decisions of both the judiciary and the Constitutional Court, that have made wide reference to ECHR case law without being able to solve the most debated problems. Given this situation, the author suggests that a preferable solution would be renewed focus on the full fledged enhancement of both individual and social attitudes concerning the right to health
From species diffusion to poroelasticity and the modeling of lamina cribrosa
No full textThe Lamina Cribrosa is a part of the optic nerve head acting as a scaffold for collecting the retinal ganglion cell axons. It can be modeled as a poroelastic material where the saturated porosity stands for the capillary network running inside the collagen beams. Our aim is to study the interaction between tissue porosity, deformation and hemodynamics. To this end we first focus on the derivation of a poroelastic model in a rather general case, using as a prototype a model of species diffusion in an elastic material. Then we outline the clinical significance of the mechanical behavior of the Lamina Cribrosa and show, through numerical simulations, how an increased intraocular pressure results in a deformation affecting porosity and blood perfusion. We emphasize how the model behavior relies on the free energy expression
