Productive Efficiency of Decanters with Short and Variable Dynamic Pressure Cones

2003

Abstract This paper presents the results of experimental trials carried out on third-generation, variable dynamic pressure cone decanters to assess machine performance and adjust the process parameters for optimum extraction yield. The results obtained led to the following conclusions: the regulation of the differential velocity screw/bowl allows a better performance of the decanter at low dilutions of the olive paste; it is possible to obtain high efficiency at a low dilution of the olive paste achieving a higher minor compounds content and the more advanced system of regulation leads to better results according to the variations of the ratio between liquid and solid phases, thus optimisin…

ICT demand behaviour: An international comparison

2009

This study aims to provide some empirical explanations for the gaps in ICT diffusion between industrialized countries, especially European countries vis-à-vis the United States. The panel data cover eleven OECD countries: Austria, Denmark, Finland, France, Germany, Italy, Japan, the Netherlands, Spain, the United Kingdom and the United States. These annual macroeconomic data span the 1981-2005 period.The analysis provides some original results: (i) the impact on ICT diffusion of the level of education and market rigidities has changed over time. The correlation of ICT diffusion, positive with the level of education and negative with market rigidities, increased over time (in absolute terms)…

Amor y misoginia. A propósito de "amor fou" de Marta Sanz

2019

En este breve texto abordamos una aproximación a las relaciones amorosas, la misoginia romántica y su vinculación con las relaciones asimétricas de género en sociedades occidentales contemporáneas, a partir del análisis discursivo de la novela Amor Fou de la escritora Marta Sanz (2018). Todo discurso narrativo imaginado es, simultáneamente, producto de la realidad social e histórica en la que se inscribe y productor de las representaciones simbólicas hegemónicas que sustentan relaciones instituidas de desigualdad entre los distintos agentes sociales. Desde esta perspectiva, el análisis que proponemos de esta ficción narrativa se inscribe en el cruce de algunas renovaciones epistemológicas y…

Institutional perspectives in transition : research groups’ profiles and embeddedness in organisational and national context

2019

Research into differentiation and profiling of knowledge producing institutions through the lenses of institutional logics and field embeddedness have proliferated in recent years. By discussing this process in the context of research groups, as those basic units in which knowledge production epistemically and practically takes place, this article offers a contribution to the theoretical discussion on organisational differentiation. Based on a small-N comparative case study of research groups operating in different national and organisational contexts on a single, highly competitive and interdisciplinary applied sciences field, nanosciences, the article proposes research group profiles as h…

Fuzzy logic-decision-making system dedicated to evaluation of logistics project effectiveness

2016

Background: Project effectiveness is synonymous with project success. It is measured or assessed in terms of the degree to which project objectives are achieved. This paper presents an approach to evaluating the effectiveness of logistics projects. The starting point is the analysis of the current state of knowledge in the area of assessing project effectiveness, including logistics projects. The purpose of the study was to identify the critical factors determining the success of logistics projects and develop a model of logistics project effectiveness. Methods: The paper is based on the available recent scientific-theoretical research and publications and on practical studies in 25 enterpr…

Chemical Variability and Pharmacological Potential of Propolis as a Source for the Development of New Pharmaceutical Products

2022

This review aims to analyze propolis as a potential raw material for the development and manufacture of new health-promoting products. Many scientific publications were retrieved from the Scopus, PubMed, and Google Scholar databases via searching the word "propolis". The different extraction procedures, key biologically active compounds, biological properties, and therapeutic potential of propolis were analyzed. It was concluded that propolis possesses a variety of biological properties because of a very complex chemical composition that mainly depends on the plant species visited by bees and species of bees. Numerous studies found versatile pharmacological activities of propolis: antimicro…

Does oral health affect food comfortability and bolus properties during consumption of dairy products in elderly population?

2017

The elderly population is growing increasingly. In 2030, 1/3 of the population will be over 60 years old. However this population has specific nutritional needs and often, oral impairments such as loss of tooth and/or decrease of salivary flow. Therefore it is necessary to develop foods adapted for the elderly, in terms of organoleptic properties and nutritional composition. In this context, the purpose of this work is to study the impact of oral impairments of elderly persons on food comfortability and bolus properties during the consumption of dairy products.76 elderly persons (ages 66 to 88, 42 women and 34 men), with or without oral health problems in terms of dental and/or salivary sta…

Configuration of Strawberry Yield, Nutritional and Functional Traits in Response to LPE Application in a Two-Year Study

2023

Lysophosphatidylethanolamine (LPE) is a promising natural lysophospholipid which can be employed as a growth regulator for horticultural purposes. The present research was accomplished to investigate the effects of LPE (0 or 10 ppm) on the yield and quality of “Savana” strawberry plants grown during two consecutive cultivation cycles (I (2020–2021); II (2021–2022)). Plants cultivated in year I and treated with LPE revealed the highest total yield (838.3 g plant−1), marketable yield (735.4 g plant−1) and average marketable fruit weight (39.8 g plant−1). Fruits from year II plants treated with LPE had the highest total phenolics concentration (491.4 m…

Centrality Dependence of the Charged-Particle Multiplicity Density at Midrapidity in Pb-Pb Collisions at √sNN = 5.02 TeV

2016

The pseudorapidity density of charged particles, dNch=dη, at midrapidity in Pb-Pb collisions has been measured at a center-of-mass energy per nucleon pair of √sNN=5.02 TeV. For the 5% most central collisions, we measure a value of 1943±54. The rise in dNch=dη as a function of √sNN is steeper than that observed in proton-proton collisions and follows the trend established by measurements at lower energy. The increase of dNch=dη as a function of the average number of participant nucleons, hNparti, calculated in a Glauber model, is compared with the previous measurement at √sNN=2.76 TeV. A constant factor of about 1.2 describes the increase in dNch=dη from √sNN=2,76 to 5.02 TeV for all central…
