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…
Absorption And Transferring Of The Coghlear Fluids
1968
The perilymph is absorbed in the loose connective tissue of the modio-lum, the endolymph is absorbed in the planum limbi and the interstitial liquid of the organ of Corti in the inner spiral sulcus. The basin of the vein of the aqueduct of the cochlea in a fetal phase transfers almost only perilymph. When fully developed, many veins of the above-said basin are obliterated and the remaining ones transfer more blood than perilymph. From the interstitial spaces of the limbus the endolymph flows into the capillaries towards the inner auditory veins and the interstitial liquid of the organ of Corti flows towards the same veins by means of short lymphatic vessels.

Quantum computing algorithms and peat extracts, a Chinese dictionary and skin stem cells, carbon nanowire switches and a catalogue of stars – the research results produced by the University of Latvia scientists are as varied as the directions of studies at the University of Latvia. Our goal is to provide science-based higher education in the key areas of consequence for Latvia’s people, economy, nature and public health, to make Latvia known in the world through our achievements in science and innovation. Over the past few years the research of the UL scientists has been extremely productive, largely due to the European Union funds to support graduate and doctoral students, new research gro…
Optimization on ports activation towards energy efficient data center networks
2018
Nowadays, Internet of thing including network support (i.e. checking social media, sending emails, video conferencing) requires smart and efficient data centers to support these services. Hence, data centers become more important and must be able to respond to ever changing service requirements and application demands. However, data centers are classified as one of the largest consumers of energy in the world. Existing topologies such as ScalNet improves the data center scalability while leading to enormous amounts of energy consumption. In this paper, we present a new energy efficient algorithm for ScalNet called Green ScalNet. The proposed topology strikes a compromise between maximizing …
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…

La aceptación tecnológica de las Apps y su influencia en la co-creación, el engagement y la calidad de la relación: crear valor para el cliente en el…
2022
Impulsada por la acelerada proliferación de las tecnologías de la información y la comunicación, la economía colaborativa ha surgido como una tendencia emergente en el comportamiento del consumidor que cambia la forma en que se proporcionan y consumen los productos y servicios. El propósito de este estudio fue crear y probar un modelo holístico que explique las intención de uso y de co-creación de los usuarios de aplicaciones de entrega de comida a domicilio – FDA en Colombia a partir del contexto de la economía colaborativa. Sobre la base de varios enfoques académicos, este estudio se propuso a partir del Modelo de Aceptación Tecnológica – TAM, la lógica dominante del servicio, la teoría d…
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.
COMPARISON OF THE COURSE SYLLABUS OF THE THEORY SUBJECT "CHEMISTRY" IN CHEMISTRY GRADE AND IN ENGINEERING STUDIES
2016
Comunicació presentada a INTED2016, 10th International Technology, Education and Development Conference. (March 7-9, 2016, Valencia, Spain). The aim of the chemistry-related subjects, taught in the first academic year of several grades at the University Jaume I, is to provide a broad overview about general chemistry. However, these defined subjects are adapted to the structure, objectives and curricula of each grade. In this paper, a comparison of the course syllabus of the Chemistry subjects taught in the "Chemistry grade" and in several "Engineering grades" (Agricultural, Mechanical, Electrical, Industrial Technology and Chemical) is detailed. The differences and similarities of the subje…
Online optimization of a multi-conversion-level DC home microgrid for system efficiency enhancement
2017
In this paper, an on-line management system for the optimal efficiency operation of a multi-bus DC home distribution system is proposed. The operation of the system is discussed with reference to a distribution system with two conversion stages and three voltage levels. In each of the conversion stages, three paralleled DC/DC converters are implemented. A Genetic Algorithm performs the on-line optimization of the DC network’s global efficiency, generating the optimal current sharing ratios of the concurrent power converters. The overall DC/DC conversion system including the optimization section is modelled using MATLAB/Simulink. Thanks to the implemented online algorithm, considering …
