Le cadre de sante entre logiques d'utilité économique et logiques de soins hospitaliers
2010
The public hospital first line manager has to organize the activity of his care unit on the basis of arbitrations between two systems of logic that come more and more frequently in conflict: - The market logic / the public hospital logic - The care process logic / the patient's path logic - The function logic / the professional logic - The managerial logic / the logic "bureaucratic"
Impact COVID-19 pandemic on implementation industry 4.0 in enterprises and supply chains
2021
Purpose: The aim of this study is to discuss the impact COVID-19 pandemic on implementation 4.0 technologies in enterprises and supply chains. Design/methodology/approach: The study performs review of literature to identify key aspects of Industry 4.0, the COVID-19 pandemic in the economy. Findings: The paper explained the changes in the functioning of enterprises and supply chains and their transformation towards Industry 4.0. The authors defined the impact of the COVID-19 pandemic in the context of applying technology trends of the Industry 4.0 by enterprises and supply chains. We claim that in the enterprises and supply chains will be the need to invest in new technologies for the long t…
Current transformers effects on the measurement of harmonic active power in LV and MV networks
2011
The harmonic active power is used to determine the location of polluting loads, the direction of harmonic power flow and to estimate how consequential a certain current harmonic source is. The highest uncertainties, when measuring harmonic active power, are introduced by the current and voltage transducers. This paper presents experimental results which show the impact of current transformers (CTs) on the accuracy of the harmonic power measurements. An expression for the evaluation of the power error in distorted conditions was developed which can be easily utilized in the case of linear current transducers. It is shown how CTs cannot be considered linear transducers and how the higher the …
Free school meals as an opportunity to target social equality, healthy eating, and school functioning: experiences from students and teachers in Norw…
2021
Background There are no national arrangements for free school meals provision in Norway despite this being an important opportunity to improve children's and adolescents' nutritional status and ultimately their physical and cognitive development. During a one academic year (2014-2015), a group of Norwegian sixth graders were served a free healthy school meal in a project called 'The School Meal Project'. Objective To explore students' and teachers' experiences of receiving free school meals after the free school meal in 2015 and 5 years later. Design In-depth, semi-structured interviews with separate groups in 2015 and in 2020 were conducted face to face or via telephone or digital platform…
Combined Analysis of the Effects of Exposure to Blue Light in Ducks Reveals a Reduction in Cholesterol Accumulation Through Changes in Methionine Met…
2021
Monochromatic light is widely used in industry, medical treatment, and animal husbandry. Green-blue light has been found to stimulate the proliferation of satellite cells and the results of studies on the effects of blue light on poultry vary widely. It would be worthwhile to study the effect of blue light on poultry growth and how exposure to blue light affects metabolism and the intestinal microbiota. In this study, we irradiated Cherry Valley ducks with 460 nm wavelength light (blue light) for 3 weeks to explore the effects of blue light in comparison to those of white light (combined wavelength light) on animal growth and development. Our results showed that, under exposure to blue ligh…
A multi objective approach to short food supply chain management
2017
Conventional supply chains, involving several stages and various intermediaries, are affected by some well- known forms of inefficiencies and drawbacks. Besides the increase of market price consequent to multiple marginalization, such supply chains generally suffer of significant post-harvest losses and product waste. In this context, short food supply chains have been recently proposed as different systems capable of delivering higher quality products while promoting sustainability and efficiency. Across the EU, a growing number of consumers choose to buy food products on local farmers' markets, associating local products with higher quality standards (freshness, nutritional value), health…
The possibilities of energy storage in bulk materials
2018
The increased demand for energy from renewable sources entails the development of storage systems. The purpose of these systems is to supply energy on demand during periods which may not be concurrent with the time of the most efficient production of this energy. Various systems are being developed for storing energy in various forms and over various lengths of time.This paper presents selected projects and the results of studies into thermal energy storage. The results of the present author's own research into the transport of thermal energy in granular beds are also presented. The curves of temperature distribution have been determined; they are essential for the design of the thermal sto…
Climate and extreme rainfall events in the Mono river basin (West Africa): investigating future changes with Regional Climate Models.
2020
This study characterizes the future changes in extreme rainfall and air temperature in the Mono river basin where the main economic activity is weather dependent and local populations are highly vulnerable to natural hazards, including flood inundations. Daily precipitation and temperature from observational datasets and Regional Climate Models (RCMs) output from REMO, RegCM, HadRM3, and RCA were used to analyze climatic variations in space and time, and fit a GEV model to investigate the extreme rainfalls and their return periods. The results indicate that the realism of the simulated climate in this domain is mainly controlled by the choice of the RCMs. These RCMs projected a 1 to 1.5 °
Tsunami Propagation and Flooding in Sicilian Coastal Areas by Means of a Weakly Dispersive Boussinesq Model
2020
This paper addresses the tsunami propagation and subsequent coastal areas flooding by means of a depth-integrated numerical model. Such an approach is fundamental in order to assess the inundation hazard in coastal areas generated by seismogenic tsunami. In this study we adopted, an interdisciplinary approach, in order to consider the tsunami propagation, relates both to geomorphological characteristics of the coast and the bathymetry. In order to validate the numerical model, comparisons with results of other studies were performed. This manuscript presents first applicative results achieved using the weakly dispersive Boussinesq model in the field of tsunami propagation and coastal inunda…
