Nuevas perspectivas de análisis para entender la migración cualificada del sur de Europa hacia México

2018

This article focuses on skilled migration flows from Southern Europe into Mexico. From semi-structured interviews with Spanish and Italian immigrants living in four Mexican cities of Mexico, it addresses both reasons for immigration and labour incorporation in Mexican labour markets. Specifically, it explores: i) the role of the economic crisis and the lack of good employment in the countries of origin as a key factor when deciding an international migration; ii) the employment opportunities offered in Mexican labour markets for the highly-skilled immigrants, and iii) the role played by the Mexican state and its current immigration law when channelling this group into the labour market

Effect of kinematic viscosity over the dynamic properties of an extra-virgin olive oil

2011

Previous studies 1,2 have shown that kinematic viscosity values of food oils depend on the presence of added solvents and on the nature of the oil under investigation (e.g., geographical origin and treatments prior to oil production). However, to the best of our knowledge, only one paper 3 dealt with the correlation between viscosity values and relaxation times of simple pure alkyl compounds. Up to now, no papers have been found in literature dealing with viscosity of complex mixtures and their relaxometric properties. In this study, we intended to investigate the effect of kinematic viscosity over the dynamic properties of an extra-virgin olive oil which is known as a very complex mixture …

Influence of Distance from the Host on Parasitisation by

2019

The olive fruit fly, Bactrocera oleae, is considered the main olive pest worldwide, and has been the target of biological control programmes through the release of the braconid parasitoid Psyttalia concolor. Laboratory tests were performed to evaluate the influence of distance from the host on parasitisation, placing larvae of the substitute host Ceratitis capitata at seven distances (0, 0.5, 1, 1.5, 2, 2.5, 3 mm) and four different time periods (7, 15, 30, 60 min). Moreover, field collected olives of Ogliarola Barese cultivar infested by B. oleae were exposed to P. concolor females to confirm its ability to parasitise B. oleae in small olives. Psyttalia concolor oviposition was inhibited a…

Influence of O2 on extra virgin olive oil fatty acids composition during malaxation

2017

Many variables are related to extra virgin olive oil (EVOO) quality and, therefore, to its polyphenols content and fatty acids composition including the steps that lead to EVOO extraction, considering that it is mainly contained in the vacuoles of the fruit mesocarp. The main steps of EVOO production are: harvest, crushing, malaxation, centrifugation, storage and filtration. Considering the olive oil extraction procedures, many studies have been conducted in recent years on oil mill plant and processes for improving EVOO quality. Malaxer is the most studied machine among all; it is responsible for malaxation, which represents a very important and critical step in the EVOO extraction process…

Application of EMI and FDR Sensors to Assess the Fraction of Transpirable Soil Water over an Olive Grove

2018

Accurate soil water status measurements across spatial and temporal scales are still a challenging task, specifically at intermediate spatial (0.1–10 ha) and temporal (minutes to days) scales. Consequently, a gap in knowledge limits our understanding of the reliability of the spatial measurements and its practical applicability in agricultural water management. This paper compares the cumulative EM38 (Geonics Ltd., Mississauga, ON, Canada) response collected by placing the sensor above ground with the corresponding soil water content obtained by integrating the values measured with an FDR (frequency domain reflectometry) sensor. In two field areas, characterized by different soil clay conte…

The author analyses the parallel components of the brevity parameter between the written and the film narrative, and, at the same time, the languages autonomy that each one involves, starting from the specific performance option in two versions of the tale Redacció (‘Composition’) by Quim Monzó.

Bioactivity of Carlina acaulis essential oil and its main component to the olive fruit fly, Bactrocera oleae: ingestion toxicity, electrophysiologica…

2021

In recent years, botanical insecticides based on essential oils (EOs), or their main components, have received much attention as promising tools for Integrated Pest Management, due to their environmental safety and low side effects on non-target organisms. In this study, Carlina acaulis EO and its main component, carlina oxide, recently proven to be effective larvicidal and adulticidal agents against some insect pests, were analyzed for their toxicity, electroantennographic (EAG), and behavioral responses to adult olive fruit fly (Bactrocera oleae). The C. acaulis EO was more toxic to the tephritid than the carlina oxide, and both were more toxic to the same insect pest than EOs from other …

Controlling the atmosphere in the malaxation machine headspace in order to improve the quality of Sicilian extra virgin olive oils

2012

During the mechanical extraction process of Virgin Olive Oil (VOO) some important physical phenomena and enzymatic transformations occur influencing the final product quality. The control of process parameters is crucial to ensure the quality of VOO, therefore process monitoring and control is a fundamental requirement in the modern VOO processing industry. The present work proposes a research performed in order to develop a system for the oxygen continuous monitoring inside the malaxation machine to enhance the Sicilian extra virgin olive oil typicality and to establish a correlation with the quality of the final product. The results showed that the use of oxygen during malaxation, allowed…
