Smith, Marshall and Young on division of labour and economic growth
2003
The aim of this paper is to reconstruct the theory of division of labour and economic growth proposed by Adam Smith and developed by Alfred Marshall and Allyn Young. In their approach division of labour is the main engine of growth and plays a central role in capital accumulation and technological progress. We suggest that, according to their theory: 1) economic growth is endogenous; 2) it has the nature of a cumulative, pathdependent process; and 3) it can be described as a disequilibrium process, supported by competitive forces. We argue that these aspects make the contributions of Smith, Marshall and Young still insightful for the development of growth theory, even in the light of the mo…
Estimación de la mortalidad atribuible a enfermedades laborales en España, 2004
2007
Ana M. García García (anagar@uv.es) El registro de enfermedades profesionales en España resulta insuficiente para valorar el impacto de las enfermedades de origen laboral en nuestro país. En el presente estudio se estima la mortalidad por enfermedades laborales y sus costes en base a riesgos atribuibles estimados en la literatura internacional.Métodos: Se aplican estimaciones de riesgo atribuible para la mortalidad de origen laboral calculadas por Nurminen y Karjalainen (Finlandia, 2001) al total de muertes por las enfermedades y grupos de edad relevantes en España y por comunidades autónomas en 2004. Se calculan los años potenciales de vida y de vida laboral perdidos. A partir de estos últ…

Ophthalmic: Laboratorio virtual para el diseño de nuevas lentes oftálmicas
2013
This work presents a new virtual laboratory, OPHTALMIC, developed with MATLAB GUI for using in Optics and Optometry courses as a computer tool for studying the focusing properties of multifocal diffractive both on unconventional structures both periodic and aperiodic. This virtual laboratory enables students to quickly and easily analyze the influence of the different parameters of construction and find the best solution for a user.
Dimensional analysis and stage-discharge relationship for weirs: a review
2017
Deducing the weir flow stage-discharge relationship is a classical hydraulic problem. In this regard Buckingham’s theorem of dimensional analysis can be used to find simple and accurate formulas to obtain the rating curves of different weir types. At first, in this review paper the rectangular weir that is a very common hydraulic structure is studied. It is indicated that the crest shape, approach channel width, obliquity (angle between the weir crest and the direction normal to the flow motion) and vertical inclination (pivot weir) are the key-parameters affecting the flow over the rectangular weirs. The flow over the triangular, labyrinth, parabolic, circular, elliptical, and W-weirs are …
An eco-label for the airline industry?
2017
Abstract Air travel plays a vital role in today's life because it makes remote destinations accessible and short getaways possible. Despite its benefits, air transportation contributes heavily to climate change. Behavioral change is seen as a key driver in mitigating the environmental impacts of air travel. One way to encourage behavioral change is to use eco-labels. This study explores how an eco-label could be developed for the airline industry to function as a potential driver for behavioral change. 12 interviews with airline industry experts were conducted and thematically analyzed. Empirical results were then combined with prior research and the following five criteria essential for th…
Experimental Study of Cross-flow Micro-turbines for Aqueduct Energy Recovery
2014
An important component of the management cost of aqueducts is given by the energy costs. Part of these costs can be recovered by transforming some of the many existing energy dissipations in electric energy by means of economic turbines. In this study an experimental work has been carried out: 1) to test the performance of an economic Cross-Flow turbine which maintains high efficiency within a large range of water discharges, and 2) to validate a new approximated formula relating main inlet velocity to inlet pressure. It is proved that the proposed formula, according to some simplifying assumption, exactly links inlet velocity to inlet pressure according to any possible geometry of the Cros…
The links between smart specialisation strategy, the quintuple helix model and living labs
2018
This paper analyzes how the Living Labs can be designed as tools for a more effective implementation of the Smart Specialisation Strategy (S3) within the Quintuple Helix Model. Above all, the Quintuple Helix espouses the formation of a constructive situation encompassing ecology, knowledge and innovation, and creating extensive synergy between economy, society, and democracy. In this paper, we shall be focusing on the Quintuple Helix and Living Labs geared towards creating a shared arena in which services, processes and new ways of working via technology can be developed and tested with user representatives and researchers. Since the Living Lab is a rather new research area, the number of s…
Industrial Microreactor Process Development up to Production
2008
This chapter is about industrial applications of microprocess technology. Industry is not very active in publishing not only because of confidentiality reasons but also because of the absence of direct need for a corresponding profile. Thus, one cannot expect that the ongoing developments can be shown with a similar degree of completeness, clarity and detailedness, as this is possible for reviewing scientific contributions from academy with a wealth of peer-reviewed papers. Especially, the information of major interest of what has been transferred to production and how do the companies make profit with the new technology is usually kept secret. Thus, it has to be accepted that some informat…
Agrigento Cathedral
2015
At present Agrigento Cathedral is affected by extensive damage that seems to be mainly due to partial slumping of the foundation soil. The chapter deals with the state of damage that affects the cathedral and the investigation carried out for the mechanical characterization of the construction, the formulation of an FE model and the assessment of the safety level with respect to the service loads and with respect to exceptional loads like seismic ones. In the chapter the details of the above investigation are discussed, consideration also being given to the monitoring carried out in order to understand whether the phenomenon affecting the cathedral is ongoing. The results of the monitoring …
