Rapid Evaluation of Oxidized Fatty Acid Concentration in Virgin Olive Oils Using Metal Oxide Semiconductor Sensors and Multiple Linear Regression

2009

This works aims to set up a rapid and nondestructive method to evaluate the advanced oxidation of virgin olive oils (VOOs). An electronic nose based on an array of six metal oxide semiconductor sensors was used, jointly with multiple linear regression (MLR), to predict the oxidized fatty acid (OFA) concentration in VOO samples characterized by different oxidative status. An MLR model constructed using five predictors was able to predict OFA concentration with an average validation error of 9%.

ESTIMATION OF AN EXTENDED SAM WITH HOUSEHOLD PRODUCTION FOR SPAIN 1995

2005

This paper implements the conceptual framework sketched by Pyatt (1990) to construct an extended Social Accounting Matrix for Spain in 1995 (ESAM-95) to consider, in addition to the market economy, the production of services provided by households through unpaid work. In doing so, the ESAM-95 integrates the accounts related to market activities (ESA accounts) with non-market activities (non-ESA accounts) in a consistent way. Additional classifications are introduced in both ESA and non-ESA accounts in order to disaggregate the institutional accounts by household type and those of production factors by educational level and gender. The extended SAM is useful to calibrate CGE models in which …

Fiscal sustainability in the EU: From the short-term risk to the long-term challenge

2015

Abstract The paper analyses fiscal sustainability of public debt using a dynamic computable general equilibrium model. First, we identify the short-term risk for fiscal stress at country level; second, we investigate the assumption of convergence towards the government debt threshold (medium-term challenge); and, third, the requirement that debt projections do not show unsustainable trends (long-term challenge). The empirical implementation includes 18 EU Member States. Our findings show that the constant tax rate that stabilizes the public debt converges to 50 percentage of GDP for all the sample countries and tax revenues are the main driving forces for fiscal sustainability. Also our fin…

Effects of different cellulose derivatives on drug release mechanism studied at a preformulation stage

2003

As a matter of fact, in vitro dissolution is well known to be the method of choice for the pharmaceutical industry to develop effective medicines. However, many experiments must be performed all along a new product life and they represent an overcharge of work for researchers. The purpose of this paper was to assess the relevance of new parameters obtained during preformulation stage by Nuclear Magnetic Resonance (NMR) experiments to better understand drug release mechanism. This study was carried out with three cellulose derivatives currently used as carrier matrices (Microcrystalline cellulose (MCC), Hydroxypropylmethyl cellulose (HPMC) and Ethyl cellulose (EC)). Granules and tablets were…

An overview of the methods used in the characterisation of natural organic matter (NOM) in relation to drinking water treatment

2010

Natural organic matter (NOM) is found in all surface, ground and soil waters. During recent decades, reports worldwide show a continuing increase in the color and NOM of the surface water, which has an adverse affect on drinking water purification. For several practical and hygienic reasons, the presence of NOM is undesirable in drinking water. Various technologies have been proposed for NOM removal with varying degrees of success. The properties and amount of NOM, however, can significantly affect the process efficiency. In order to improve and optimise these processes, the characterisation and quantification of NOM at different purification and treatment processes stages is important. It …

Search for Magnetic Monopoles with the MoEDAL Forward Trapping Detector in 13 TeV Proton-Proton Collisions at the LHC

2017

MoEDAL is designed to identify new physics in the form of long-lived highly-ionising particles produced in high-energy LHC collisions. Its arrays of plastic nuclear-track detectors and aluminium trapping volumes provide two independent passive detection techniques. We present here the results of a first search for magnetic monopole production in 13 TeV proton-proton collisions using the trapping technique, extending a previous publication with 8 TeV data during LHC run-1. A total of 222 kg of MoEDAL trapping detector samples was exposed in the forward region and analysed by searching for induced persistent currents after passage through a superconducting magnetometer. Magnetic charges excee…

Coevolution of parental investment and sexually selected traits drives sex-role divergence

2016

Sex-role evolution theory attempts to explain the origin and direction of male–female differences. A fundamental question is why anisogamy, the difference in gamete size that defines the sexes, has repeatedly led to large differences in subsequent parental care. Here we construct models to confirm predictions that individuals benefit less from caring when they face stronger sexual selection and/or lower certainty of parentage. However, we overturn the widely cited claim that a negative feedback between the operational sex ratio and the opportunity cost of care selects for egalitarian sex roles. We further argue that our model does not predict any effect of the adult sex ratio (ASR) that is …

The wild taxa utilized as vegetables in Sicily (Italy): a traditional component of the Mediterranean diet

2018

Background: Wild vegetables in the Mediterranean Basin are still often consumed as a part of the diet and, in particular, there is a great tradition regarding their use in Sicily.In this study, an ethnobotanical field investigation was carried out to (a) identify the wild native taxa traditionally gathered and consumed as vegetables in Sicily, comparing the collected ethnobotanical data with those of other countries that have nominated the Mediterranean diet for inclusion in the UNESCO Representative List of the Intangible Cultural Heritage of Humanity and (b) highlight new culinary uses of these plants.Methods: Interviews were carried out in 187 towns and villages in Sicily between 2005 an…

Environmental stress affects the expression of a carotenoid-based sexual trait in male zebra finches.

2007

SUMMARY Abiotic factors including thermal stress are suggested to exert constrains on sexual ornaments through trade-offs between sexual displays and physiological functions related to self-maintenance. Given the health properties of carotenoid pigments, carotenoid-based ornaments offer a relevant context in which to investigate the effect of environmental stress, such as ambient temperature, on the production and maintenance of secondary sexual traits and, also, to explore the proximate mechanisms shaping their expression. In this study, we exposed male zebra finches (Taeniopygia guttata) to environmental stress by exposing them to two temperature regimes (6 and 26°C) over a 4 week period.…
